Electrical connector

An electrical connector comprising:

• an insulative housing defining a plurality of passageways extending therethrough in a front-to-back direction;
• a plurality of contacts disposed in the corresponding passageways, respectively, each of said contacts unitarily defining a rear crimping section located in a rear portion of the corresponding passageway for securing to a corresponding wires and a front mating section located in a front portion of the corresponding passageway, the front mating section defines a U-shaped configuration in a side view with a first arm adjacent to the rear crimping section and a second arm relative farther from the rear crimping section and a bight connected between the first arm and the second arm along a longitudinal extension direction of said U-shaped configuration, and a slot extending along said longitudinal extension direction and through the front mating section in thereof a thickness direction perpendicular to said longitudinal extension direction so as to form two spaced strips in a transverse direction perpendicular to both said longitudinal direction and said thickness direction under condition that free ends of said two spaced strips on the second arm are joined together;
• wherein
• the joined free ends further extend into a recess of the housing for restraint consideration so as to prevent improper deformation of the mating section during mating.
