An electrical connector is disclosed and includes a body and a cover. The body has a first through hole and an area for conducting and accommodating solder between the first through hole and the edges of the body. The cover is movably disposed on the body. The color of the cover is lighter than that of the body. The cover has a second through hole and an area for accommodating pins between the second through hole and the edges of the cover. The second through hole corresponds to the first through hole. The second through hole has a first rim, a second rim, a third rim, and a fourth rim. The third rim and the fourth rim are parallel to a movement direction of the cover. When the cover is at an open state on the body, the area for accommodating pins and the area for conducting and accommodating solder are disengaged, the projection of the first rim and the second rim of the second through hole vertically on the body does not lie in the first through hole. It solves the problem of making mistakes in inspection.
