Then, the electric circuit module 7 is pushed along a horizontal direction (the direction of the x-axis), such that the pressing portions 253 moves above the second portions B of the fixing holes 711, such that the pressing portions 253 protrudes over and presses the top face of the circuit board 71 (as shown in FIG. 6), such that the electric circuit module 7 cannot move in the direction of the z-axis (up and down) and a part of the connection portion 252 is fixed in the second portion B of the fixing hole 711 such that the electric circuit module 7 cannot move in the direction of the y-axis (left and right).

When the first housing 1 and the second housing 2 of the present disclosure are to be assembled, as shown in FIG. 4A and FIG. 4B, first, the two first bolts 3 protruding on the inner face of the inner boards 12 of the first housing 1 are passed through the first openings 513 of the two first guiding grooves 51 of the two first guiding rails 5 at two sides of the bottom board 21 of the second housing 2, and move upward to the first vertical sections 511. The first bolt 3 can pass through the first vertical section 511 and continue to move upward, such that the first bolt 3 temporarily stops at the junction between the first vertical section 511 and the first horizontal section 512. The first bolt 3 can act as a pivot at this location, such that the first housing 1 is pivotally connected to the second housing and the first housing 1 can pivot about the first bolts 3 to turn downward to cover the second housing (referring to FIG. 1, according to the location of the pivot, rotate about the y-axis).

The first housing 1 rotates downward to cover the second housing according to the above description. As shown in FIG. 5A and FIG. 5B, the two second bolts 4 protruding on the inner face of the side boards 12 of the first housing 1 are passed through the second openings 613 of the two second guiding grooves 61 of the two second guiding rails 6 at two sides of the second board 21 of the second housing 2, and move downward to the second vertical sections 611. The second bolt 4 then pass through the second vertical section 611 and continues to move downward, such that the second bolt 4 temporarily stops at the junction between the second vertical section 611 and the second horizontal section 612. Referring to FIG. 4C and FIG. 5C, the first housing 1 is then pushed forward, such that the first bolt 3 passes through the first horizontal section 512 and moves to the first fixing node 514, and the second bolt 4 passes through the second horizontal section 612 and moves to the second fixing node 614, such that the first housing 1 and the second housing 2 are joined together (as shown in FIG. 7). The first connector 72 and the second connectors 73 are respectively aligned with the first through hole 14 and the second through holes 23, for plugging to other connectors.

At this moment, the snap bodies 242 of the elastic snaps 24 can snap into the two snap holes 15, such that the first housing 1 and the second housing 2 cannot move in the direction of the x-axis (forward and backward) with respect to each other. The two first bolts 3 and the two second bolts 4 are respectively fixed at the two first fixing nodes 514 and the two second fixing nodes 614, such that the first housing 1 and the second housing 2 cannot move in the direction of the z-axis (upward and downward) with respect to each other. The first head portions 32 of the two first bolts 3 abut the inner faces of the two first guiding rails 5, and the second head portions 42 of the two second bolts 4 abut the inner faces of the two second guiding rails 6, such that each of the two first guiding rails 5 is sandwiched between one of the two side boards 12 and the first head portion 32 of one of the two first bolts 3, each of the two second guiding rails 6 is sandwiched between one of the two side boards 12 and the second head portion 42 of one of the two second bolts 4, such that the housing 1 and the housing 2 cannot move in the direction of the y-axis (left and right) with respect to each other.

Additionally, the rear board 13 of the first housing 1 abuts one end (e.g. the rear end) of the circuit board 71, such that the electric circuit module 7 cannot move in the direction of the x-axis (forward and backward), such that the circuit board 71 is securely fixed on the protruding domes 25. When a user presses the two elastic snaps, the snap bodies 242 detach from the snap holes 25 such that the first housing 1 and the second housing 2 can be separated.

Additionally, the present disclosure can further include at least one flexible body 8. The flexible body 8 can be made of rubber or sponge. The flexible body 8 can be rectangular or other shapes. The flexible body 8 is disposed between the bottom face of the front end of the top board 11 of the first housing 1 and the upper face of the front board 22 of the second housing 2. The elasticity of the flexible body 8 can be utilized to abut between the top board 11 of the first housing 1 and the front board 22 of the second housing, so as to eliminate the gap between the first housing 1 and the second housing 2, such that the first housing 1 and the second housing 2 are tightly sealed therebetween and an upward elastic force is provided to the first housing 1, such that when the first housing 1 and the second housing 2 are to be separated, the first housing 1 can automatically spring upward to be retrieved.

The present disclosure has the following advantages. The housing assembly of the present disclosure is screw-less. Two first bolts and two second bolts are disposed on the first housing, and two first guiding rails and two second guiding rails are disposed on the second housing. Then, using the engagements between the first bolts and the first guiding rails, and the engagements between the second bolts and the second guiding rails, the first housing and the second housing become mutually cooperating components.
