ABSTRACT:
An electric connector comprising a dielectric housing with front and rear surfaces and a plurality of cavities extending longitudinally between the surfaces, each cavity having a pair of oppositely oriented guide ledges frontwardly disposed in the cavity and laterally extending inwardly from diagonally opposite side portions of the cavity, and a plurality of electrical contacts mounted in the housing, each contact including a pair of opposed spring arms with frontwardly disposed, inwardly bowed engagement portions for receiving a mating contact and a rearwardly disposed tail portion for receiving a conductive element, the engagement portions further including a pair of laterally offset tabs arranged for abutting engagement with the ledges to individually position and limit inward movement of each engagement portion without restricting outward movement of the engagement portion. In one embodiment, the guide ledges extend rearwardly to rear cam surfaces outwardly inclined to engage the tabs and guide the spring arms during insertion from the rear into each cavity. The embodiment also includes a rear base for supporting an upper body portion with the cavities and with rectangular openings through which the contact tail portions extend and are restricted in rotation.
