I claim the ornamental design for an electrical connector, as shown and described.
FIG. 1 is an outside elevational view of an electrical connector, after bending, showing my new design;
FIG. 2 is an end perspective view of the electrical connector after bending;
FIG. 3 is an inside perspective view of the right electrical connector, after bending;
FIG. 4 is a right outside perspective view of the electrical connector before bending of tabs;
FIG. 5 is a left outside perspective view of the electrical connector before bending;
FIG. 6 is a top left perspective view of the electrical connector before bending; and,
FIG. 7 is a top right perspective view of a electrical connector before bending.
The broken lines in FIGS. 1-3 are included for the purpose of showing the environment of the electrical connector, and form no part of the claimed design.
