  • Patent number: 5676555
    Abstract: Disclosed is a card edge connector which has a pivoting latching mechanism that has a pair of parallel fingers that direct inward transverse forces on the opposed sides of the printed wiring board to secure it in the connector. The connector also includes a plate on each of the contact elements which prevents overstressing of the arcuate element of the contact. The plate also includes a longitudinal projection and an opposed longitudinal recess so that the contact elements resist axial forces.

  • Patent number: 5516304
    Abstract: An electrical connector comprises a housing having latch members at both ends of the housing and a pair of metal fasteners capable of clamping on the latch members. The housing has a longitudinal groove for receiving a daughter board. The metal fastener includes a fixing section and a spring section which substantially extends uprightly therefrom. The fixing section clamps on the housing. The spring section is provided with a restriction leg and a slot which are formed by punching, and the restriction leg is substantially vertical to the surface of the spring section. When the metal fastener clamps on the housing, a rib provided at the end portion of the latch member fits the slot of the spring section so as to prevent the side shifting of the metal fastener.
