Description

FIELD OF THE INVENTION

The present invention relates generally to telecommunications connectors and to methods for assembling telecommunications connectors.

BACKGROUND OF THE INVENTION

Modular connectors such as modular plugs and modular jacks are commonly used in the telecommunications industry. FIG. 1 illustrates an exemplary modular connector 20 (e.g., an RJ45 connector). The connector 20 includes eight spring contacts numbered from one to eight. The eight contacts form four separate circuits or pairs for conveying twisted pair (e.g., tip and ring) signals. FIG. 1 shows a conventional pairing configuration in which springs 4 and 5 form a first circuit, springs 3 and 6 form a second circuit, springs 1 and 2 form a third circuit, and springs 7 and 8 form a fourth circuit.

Crosstalk can be a significant source of interference in telecommunications systems. Crosstalk is typically caused by the unintentional transfer of energy from one signal pair to another. Commonly, the transfer of energy is caused by inductive or capacitive coupling between the conductors of different circuits. Crosstalk is particularly problematic in modular connectors because of the close spacing of the contact springs. The most severe crosstalk frequently occurs between the two inside circuits of a modular connector (i.e., the circuits formed by contact springs 4, 5 and 3, 6).

To reduce crosstalk, a variety of different spring configurations have been developed. Often, the spring shapes are quite complicated and the springs can be difficult to assemble and maintain in the desired orientations suitable for reducing crosstalk. What is needed is an improved method for assembling contact springs in a telecommunications connector.

SUMMARY OF THE INVENTION

One aspect of the present invention relates to an electrical connector including a spring mounting body having a clip receiving structure. A plurality of contact springs are mounted on the spring mounting body. A clip is inserted within the clip receiving structure to stabilize the contact springs. Portions of the contact springs are captured between the clip and the spring mounting body.

A method for mounting telecommunication connector springs including providing a dielectric spring mounting body, and positioning a plurality of contact springs at desired locations on the spring mounting body. The method also includes stabilizing the contact springs by capturing portions of the contact springs between the spring mounting body and a dielectric clip. The method further includes connecting the clip to the spring mounting body with the captured portions of the contact springs remaining captured after the clip has been connected to the spring mounting body.

A variety of advantages of the invention will be set forth in part in the description that follows, and in part will be apparent from the description, or may be learned by practicing the invention. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention as claimed.

DETAILED DESCRIPTION

Reference will now be made in detail to exemplary aspects of the present invention that are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

FIGS. 2A and 2B illustrate a modular jack 30 constructed in accordance with the principles of the present invention. The modular jack 30 includes a housing 32 and an insert assembly 34 adapted to snap fit within the housing 32. The insert assembly 34 includes an insert body 36, a circuit board 42, a spring retaining clip 230 and a plurality of contact springs 44 (e.g., eight contact springs). insulation displacement connectors 38 are provided on a top side of the insert body 36. The springs 44 are secured to the insert body 36 by the retaining clip 230. When assembled, the circuit board 42 mounts to a bottom side of the insert body 36, and the contact springs 44 extend above the top side of the insert body 36. Tracings (not shown) on the circuit board 42 provide electrical connections between the contact springs 44 and respective ones of the insulation displacement connectors 38. Details relating to a circuit board tracing configuration suitable for use with the present invention are disclosed in U.S. Pat. No. 6,089,923 issued Jul. 18, 2000, which is hereby incorporated by reference.

To mount the insert assembly 34 in the housing 32, the insert assembly 34 is placed in a channel 41 of the housing 32. The insert assembly 34 is then slid toward the front of the housing 32 until resilient locking tabs 46 of the insert body 36 snap fit within corresponding openings 48 defined by the housing 32. When the insert assembly 34 is snap fit within the housing 32, the springs 44 of the insert assembly 34 are separated by a divider 39 positioned within the housing 32.

FIG. 3 shows a modular plug 50 inserted within a port 52 defined by a front side 54 of the housing 32. The plug 50 includes eight contacts 56 that provide electrical connections with the contact springs 44 of the modular jack 30 when the plug 50 is inserted within the port 52. For example, FIG. 4 shows one of the contacts 56 in electrical contact with one of the contact springs 44. As shown in FIG. 4, the contact springs 44 have been pushed into a deflected orientation by the contacts 56. For the purpose of this application, the phrase “deflected orientation” is intended to mean the orientation of the contact springs 44 when the plug 50 is inserted within the port 52. For clarity, the insert body 36 is not shown in FIG. 4.

Electrical contact between the contacts 56 and the contact springs 44 is preferably made along a simple line of contact 58. The line of contact 58 is best shown schematically at FIG. 5A. For clarity purposes, the plug 50 is not shown in FIG. 5A such that the springs 44 are more clearly visible.

FIGS. 5A-5C illustrate the circuit board 42 and the contact springs 44 in isolation from the remainder of the modular jacks 30. In all of FIGS. 5A-5C, the contact springs 44 have been depicted in the deflected orientation of FIG. 4.

Referring now to FIG. 5B, the contact springs 44 are located at eight separate spring positions numbered 1-8. Similar to the prior art pin assignment of FIG. 1, the contact springs at positions 4 and 5 preferably form a first pair, the contact springs at positions 3 and 6 preferably perform a second pair, the contact springs at positions 1 and 2 preferably form a third pair, and the contact springs at positions 7 and 8 preferably form a fourth pair. Other pairings can also be used.

The contact springs 44 preferably include springs having three different geometric configurations. For example, the contact springs 44 are shown including four front springs 60, two middle springs 62 and two rear springs 64. Preferably, the front springs 60 are located at spring positions 2, 4, 6 and 8; the middle springs 62 are located at spring positions 1 and 7; and the rear springs 64 are located at spring positions 3 and 5. As will be described later in the specification, the front and middle springs 60 and 62 preferably comprise rearwardly extending springs, and the rear springs 64 preferably comprise forwardly extending springs.

Referring again to FIG. 5B, the front, middle and rear springs 60, 62 and 64 respectively include terminal ends 66, 68 and 70 (i.e., posts) that terminate within the circuit board 42. The terminal ends 66 of the front springs 60 are aligned along a front reference line 72, the terminal ends 68 of the middle springs 62 are aligned along a middle reference line 74, and the terminal ends 70 of the rear springs 64 are aligned along a rear reference line 76. The middle reference line 74 is positioned between the front and rear reference lines 72 and 76. Preferably, the reference lines 72, 74 and 76 are substantially parallel. The spacing between the reference lines 72, 74 and 76 provide staggering between the terminal ends 66, 68 and 70. This staggering is advantageous because additional space is provided for terminating the spacings 44 at the circuit board 42 (e.g., clearance for solder pads is provided). Clearance is also provided for allowing transmission lines to be passed between the springs 44.

FIG. 6 shows one of the front springs 60 in both a deflected orientation 78 and in a non-deflected orientation 80. The terminal end 66 of the front spring 60 is shown extending through the circuit board 42. The circuit board 42 includes a front end 82 adapted to be positioned at the front side 54 of the housing 32 and a rear end 84 adapted to be positioned at the rear side 31 of the housing 32.

Referring still to FIG. 6, the terminal end 66 of the front spring 60 extends vertically upward from the circuit board 42. A forward extension 86 extends in a forward direction from the terminal end 66. A first bend 88 (e.g., a bend of about 90 degrees) interconnects the terminal end 66 and the forward extension 86. The forward extension 86 preferably extends slightly upward as it extends in the forward direction. A second bend 90 reverses the direction in which the forward extension 86 extends. For example, the second bend reverses the direction of the spring 60 from a forward direction at the forward extension 86, to a rearward direction at a proximal portion 92 of the front spring 60.

The proximal portion 92 extends from the second bend 90 to a contact region 94 that corresponds to the line of contact 58 at which the spring 60 will contact its respective contact 56 of the plug 50. The spring 50 further includes a distal portion 96 that extends from the contact region 94 toward the rear end 84 of the circuit board 42. Preferably, the proximal and distal portions 92 and 96 are aligned along a single straight line 98.

The front spring 60 can be referred to as a rearwardly extending spring because the distal portion 96 extends from the contact region 94 toward the rear end 84 of the circuit board 42. The proximal and distal portions 92 and 96 cooperate to form an upper resilient cantilever 89 having a base at the second bend 90. When moving between the deflected and non-deflected orientations 78 and 80, the cantilever 89 flexes primarily it's base (e.g., at the second bend 90).

FIG. 7 illustrates one of the middle springs 62 in both a deflected orientation 100 in a non-deflected orientation 102. The terminal end 68 of the middle spring 62 extends vertically upward from the circuit board 42. A forward extension 104 extends in a forward direction from the terminal end 68. At first bend 106 (e.g., approximately a 90 degree bond) provides a transition between the terminal end 68 and the forward extension 104. A second bend 108 reverses the direction of extension of the forward extension 104. From the second bend 108, a proximal portion 110 of the middle spring 62 extends in a rearward direction to a contact region 112 that corresponds to the line of contact 58 at which the spring 62 will contact its respective contact 56 of the plug 50.

A distal portion 114 of the contact spring 62 extends from the contact region 112 in a rearward direction toward the rear end 84 of the circuit board 42. Preferably, the proximal portion 110 and the distal portion 114 are aligned along a single straight line 116 and form an upper cantilever 115 having a base end at the second bend 108. When moving between the deflected and non-deflected orientation 100 and 102, the cantilever 115 flexes primarily at the second bend 108. The spring 62 can be referred to as a rearwardly extending spring because the distal portion 114 extends in a rearward direction from the contact region 112.

FIG. 8 illustrates one of the rear springs 64 in both a deflected orientation 118 and a non-deflected orientation 120. The terminal end 70 of the rear spring 64 extends perpendicularly from the circuit board 42. A rearward extension 122 extends in a rearward direction from the terminal end 70. A first bend 124 (e.g., about a 90° bend) provides a transition between the terminal end 70 and the rearward extension 122. A second bend 126 reverses the direction of extension of the rearward extension 122. A proximal portion 130 extends from the second bend 126 in a forward direction to a contact region 132 of the spring 64. The contact region 132 corresponds to the line of contact 58 at which the spring 64 will electrically contact one of the contacts 56 of the plug 50. A distal portion 134 of the rear spring 64 preferably extends in a forward direction from the contact region 132 toward the front end 82 of the circuit board 42.

The distal and proximal portions 134 and 130 are not aligned along a common straight line. Instead, the proximal and distal portions 130 and 134 are preferably aligned at an obtuse angle relative to one another. The contact region 132 is located at an apex between the proximal and distal portions 130 and 134, and the proximal and distal portions 130 and 134 extend away from the contact region 132 in a direction generally toward the circuit board 42. The proximal and distal portions 130 and 134 form a cantilever 135 having a base end at the second bend 126. When moving between the deflected and non-deflected orientations 118 and 120, the cantilever 135 flexes primarily at the second bend 126. The spring 64 can be referred to as a forwardly facing spring because the distal portion 134 extends in a forward direction from the contact region 132.

Referring to FIG. 5C, the contact spring 44 are shown in a deflected orientation. As illustrated, the distal portions 96 of the front springs 60 (i.e., the rearwardly facing contact springs) define an angle θ₁ relative to the proximal portions 130 of the rear springs 64 (i.e., the forwardly facing contact springs) that is preferably greater than 10°. In other embodiments, the angle θ₁ is greater than 15°, 20°, 25°, 30°, or 35°. In one particular embodiment of the present invention, the angle θis about 38.5°.

Referring still to FIG. 5C, proximal portions 92 of the front springs 60 (i.e., the rearwardly facing contact springs) define an angle θ₂ relative to the distal portions 134 of the rear springs 64 (i.e., the forwardly facing contact springs) that is preferably greater than 10°. In certain embodiments of the present invention, the angle θ₂ is greater than 15°, 20° or 25°. In one particular embodiment of the present invention, the angle θ₂ is about 26.6°.

To further reduce crosstalk, it is also noted that the distal portions 114 of the middle springs 62 are arranged in a non-parallel relationship with respect to the distal portions 96 of the front springs 60. Additionally, the proximal portions 110 of the middle springs 62 are arranged in a non-parallel relationship with respect to the proximal portions 92 of the front springs 60.

The above-described configurations assist in reducing crosstalk between the springs located at positions 3-6 because the distal portions 96 of the front springs 60 relatively quickly diverge from a parallel relationship with respect to the proximal portions 130 of the rear springs 64, and the proximal portions 92 of the front springs 60 relatively quickly diverge from a parallel relationship with respect to the distal portions 134 of the rear springs 64. The divergence preferably initiates as the springs 60, 64 extend away from the line of contact 58. Therefore, significant portions of the springs 60 and 64 are spaced relatively far apart thereby reducing the intensity of capacitive coupling.

As shown in FIG. 5B, the front springs 60 are shown at positions 3 and 5. It will be appreciated that this positioning could be reversed such that the front springs 60 are located at positions 3 and 5, and the rear springs 64 are located at positions 4 and 6. Also, in other embodiments, forwardly extending springs can be used at positions 1, 2, 7 and 8; and forwardly and rearwardly extending contacts can be alternated at positions 3-6. In still another embodiment, forwardly extending contacts and rearwardly extending contacts can be alternated throughout positions 1-8.

The insert body 36 of the jack 30 is preferably made of a dielectric material such as polycarbonate. The insert body 36 includes a top side 200 (shown in FIG. 9A) and a bottom side 202 (shown in FIG. 9B). The insert body also includes a front end 204 (i.e., a spring supporting end) positioned opposite from a rear end 206. The front end 204 is preferably configured to assist in holding the springs 44 in the configuration of FIGS. 5A-5C. For example, as best shown in FIG. 9A, the front end 104 of the insert body 36 includes four front spring bend guides 208 and two middle spring bend guides 210. As shown in FIG. 10, the front spring bend guides 208 are preferably radiused (i.e. curved) to complement and support the second bends 90 of the front springs 60. As shown in FIG. 11, the middle spring bend guides 210 are preferably radiused to complement and support the second bends 108 of the middle springs 62. The middle spring bend guides 210 are preferably rearwardly and downwardly offset relative to the front spring bend guides 208.

Referring to FIG. 9B, the bottom of the insert body 36 also includes structure for maintaining the springs 44 in the configurations of FIGS. 5A-5C. For example, the bottom side 202 includes four front spring channels 212 for receiving the forward extensions 86 of the front springs 60. FIG. 10 shows the forward extension 86 of one of the front springs 60 positioned in one of the front spring slot 212. As also shown in FIG. 10, rear side ends 213 of the front spring slots 212 are radiused to match the curvatures of the first bends 88 of the front springs 60.

The bottom side 202 also defines two middle spring channels 214 for receiving the forward extension 104 of the middle springs 62. FIG. 11 shows the forward extension 104 of one of the middle springs 62 positioned in one of the middle spring channels 214. As shown in FIG. 11, rear ends 215 of the middle spring channels 214 are radiused to match the curvatures of the first bends 106 of the middle springs 62. The middle spring channels 214 are preferably adapted to position the forward extension 104 of the middle springs 62 at a lower elevation than the forward extension 86 of the front springs 60.

The insert body 36 further defines two rear spring slots 216 for receiving the contact regions 132 of the rear springs 64. As shown in FIG. 12, the rear spring slots 216 extend completely through the inner body 36 such that the contact regions 132 of the rear springs 64 can extend from the bottom side 202 of the insert body to the top side 200 of the insert body 36.

The springs 44 are secured (i.e., fastened, retained, otherwise held in place) to the insert body 36 by the retaining clip 230. The clip 230 also stabilizes the springs 44 (i.e., the clip 230 resists movement of at least portions of the springs 44). The term “clip” will be understood to mean a number that is manufactured as a separate piece from the insert body 36 and, that is engageable with the insert body 36. The clip is preferably made of a dielectric material such as polycarbonate.

To assemble the springs on the insert body 36, the springs 44 are mounted within their respective spring retaining structure defined on the insert body 36. For example, the second bends 90 of the front springs 60 are inserted over the bend guides 208 (see FIG. 10). As so inserted, the forward extensions 86 of the front springs 60 fit within the front spring channels 212 beneath the insert body 36 and the cantilever portions 89 extend above the top side 200 of the insert body 36. Similarly, the second bends 108 of the middle springs 62 are inserted over the middle spring bend guides 210 (see FIG. 11). As so inserted, the forward extension 104 of the middle springs 62 fit within the middle spring channels 214 and the cantilever portions 115 project above the top side 200 of the insert body 36. The rear springs 64 are positioned such that the contact portions 132 extend through the slots 216 defined by the insert body 36 (see FIG. 12).

FIG. 13 shows the springs 44 positioned on the insert body 36 as described above. As shown in FIG. 13, the termination posts 66, 68 and 70 of the springs 44 project outwardly from the bottom side 202 of the insert body 36. During the assembly process, the clip 230 is used to retain the springs 44 in the position of FIG. 13. To secure the springs 44 with the clip 230, the clip is inserted in a rearward direction into a clip receiving structure 231 defined by the insert body 236. The clip receiving structure 231 includes shoulders 232 that interlock with tabs 234 of the clip 230 to prevent the clip 230 from being forwardly dislodged from the clip retaining structure 231. The tabs 234 are positioned on the end of flexible arms 235 that flex inwardly as the retaining clip 230 is inserted into the clip retaining structure 231. Specifically, during insertion of the clip 230, the tabs 234 engage ramped surfaces 236 of the shoulders 232 causing the arms 235 to flex inwardly. Once the tabs 234 pass the shoulders 232, the arms 235 snap outwardly to provide a snap fit connection.

With the retaining clip 230 inserted within the clip receiving structure 231, portions of the springs 44 are captured between the clip 230 and the bottom side 202 of the insert body. The clip 230 is prevented from being downwardly displaced from the clip receiving structure 231 by side wedges 237 that fit within the notches 238 of the insert body 36 when the retaining clip 230 is fully inserted within the clip retaining structure 231. FIG. 15 shows one of the side wedges 237 inserted within one of the notches 238.

FIGS. 14 and 15 show the clip 230 fully inserted within the insert body 36. As shown in FIGS. 14 and 15, the retaining clip 230 includes a handle 240. The handle 240 facilitates inserting the clip 230 within the clip receiving structure 231. After insertion, the handle can be removed from the remainder of the retaining clip 230 by conventional techniques such as cutting or otherwise breaking the handle 230 from the retaining clip 230.

Referring to FIGS. 16D and 16E, the retaining clip 230 includes a plurality of post retainers for precisely maintaining the position of the termination posts 66, 68 and 70 of the springs 44. For example, the post retainers include four front post retainers 242 adapted to engage and position the terminal posts 66 of the front springs 60 (see FIG. 10). Still referring to FIGS. 16D and 16E, the clip 230 also includes two middle post retainers 244 and two rear post retainers 246. The middle post retainers 244 are adapted to engage and position the terminal posts 68 of the middle springs 62 (see FIG. 11). The rear post retainers 246 are adapted to engage and position the terminal posts 70 of the rear springs 64 (see FIG. 12). All of the post retainers 242, 244 and 246 include structure for receiving or cradling the terminal end posts 66, 68, and 70. For example, as shown, the post retainers 42, 44 and 46 each have a concave, notched configuration. However, any type of notch or other structure could also be used.

The retaining clip 230 also includes structures for trapping or pressing portions of the springs 44 against the bottom side 202 of the insert body 36. For example, as shown in FIGS. 16A-16C, the clip 230 includes four front spring supports 250 for capturing the front springs 60, two middle spring supports 260 for capturing the middle springs 62, and two rear springs supports 270 for capturing the rear springs 64.

The front spring supports 250 are positioned in alignment with the front post retainers 242. As shown in FIG. 10, the front spring supports 250 include inclined planar portions 251 for pressing the forward extensions 86 of the forward springs 60 upwardly into their corresponding front spring channels 212 defined beneath the insert body 36. The front spring supports 250 also include front curvatures 253 for supporting the second bends 90 of the front springs 60, and rear curvatures 255 corresponding to the first bends 88 of the front springs 60.

The middle springs supports 260 are positioned in alignment with the middle post retainers 244. As shown in FIG. 11, the middle spring supports 260 include planar support surfaces 262 that press the forward extension 104 of the middle springs 62 into their corresponding middle spring channels 214 defined beneath the insert body 36. Rear ends of the middle spring support structures 260 are tapered to accommodate the second bends 106 of the middle springs 62. The planar support surfaces 261 are preferably positioned lower than the planar support surfaces 251 of the front spring supports 250.

The rear spring supports 270 are positioned in alignment with the rear post retainers 246. As shown in FIG. 12, the rear spring supports 270 include rounded noses 272 for supporting the second bends 126 of the rear springs 64. Planar support surfaces 271 of the rear spring supports 270 are preferably positioned higher than the planar support surfaces 251 of the front spring supports 250. The spring supports 270 press portions of the rear springs 64 against the underside of the insert body 36, and prevent the distal tips of the rear springs 64 from contacting the circuit board 44.

The retaining clip 230 further includes a front flange or lip 280 that covers and protects the second bends 90 and 108 of the front and middle springs 60 and 62 when the clip 230 is fully inserted within the clip receiving structure 231 of the insert body 36. The lip 280 projects upwardly from the spring supports 250, 260 and 270. Notches 282 are defined at a top edge of the lip 280 for providing clearance for the front springs 60.

FIG. 17 shows the clip 230 fully inserted within the clip retaining structure 231 of the insert body 36. As so inserted, the retaining clip 230 retains all of the terminal posts 66, 68 and 70 in positioned locations that correspond to the locations of through-holes 290 defined by the printed circuit board 44. Similarly, insulation displacement connector contacts 293 are also positioned in alignment with through-holes 292 defined by the printed circuit board 44. Therefore, the printed circuit board can be readily connected to the insert body 36 by pressing the two pieces together such that the terminal posts 66, 68 and 70 fit within their corresponding through-holes 290 and the insulation displacement connectors fit within their corresponding through-holes 292. Preferably, a supplemental fixture is also used to maintain alignment of the posts 66, 68 and 70. In certain embodiments, the posts 66 and 68 (shown in FIGS. 10 and 11) can be fabricated so as to be angled slightly forward prior to insertion in the circuit board 42.
