Electrical connector with contact anti-overstress means

摘要

An anti-overstress system is provided in an electrical connector which includes a dielectric housing having a contact-receiving cavity with a slot communicating the cavity with a mating surface on the outside of the housing. A contact is received in the cavity and includes a cantilevered spring contact arm disposed in the slot. The arm has a contacting portion projecting beyond the mating surface of the housing for engagement with a complementary contact of the mating connector. The spring contact arm flexes in the slot upon engagement of the contacting portion by the complementary contact. The anti-overstress system is provided between the contact and the housing and includes a pair of wings projecting from opposite sides of the spring contact arm engageable with a pair of ledges formed in opposite sides of the slot after a given amount of flexing of the spring contact arm.
