Abstract:
1. An electrical connector, comprising: a dielectric housing having a connecting end, a mating end opposite to the connecting end for allowing insertion of a mating connector, a plurality of slots arranged in the dielectric housing and passing through the connecting end and the mating end, and a plurality of stop grooves formed adjacent to the connecting end and respectively adjoining and communicating with the corresponding slots; and a plurality of terminals mounted in the corresponding slots, each of the terminals including a body, a first contact arm and a second contact arm both disposed at one side of the body and being opposite to each other, the first contact arm and the second contact arm cooperatively defining a clamping area therebetween, a retention arm being formed on a substantially middle of the body and bending outwards of the body in an opposite direction with respect to the clamping area and towards the connecting end of the dielectric housing, and a plurality of interference portions protruding outwards from opposite sides of the body and being spaced away from each other; wherein the retention arm is held against the stop groove so as to prevent the terminals from being loosened out of the slots by an excessive insertion force from the mating connector; wherein the body of the terminal has a hollow portion thereon, one end of the retention arm is integrally formed with an inner wall of the hollow portion, and the other end of the retention arm is held against the stop groove by bending the retention arm outwards of the body in a direction, which is perpendicular to a direction defined along the insertion of the mating connector.
