A self-sacrificing latching system for a pair of intermatable electrical connectors, such as a plug and receptacle, which incorporates a mechanism for unlatching same by the application of a maximum predetermined separating force, such as may be the result of an accident to the plug and receptacle. A first electrical connector includes a pair of flexible arms projecting axially therefrom, where the free end includes a bifurcated portion, while the second electrical connector includes a forward ramp surface against which the flexible arms initially ride to effect mating of the connectors. Further, there is a rearward surface slightly angled, i.e. on the order of about 4.degree. to 10.degree., from a base toward the ramp surface, and a metal spring arm mounted within the second electrical connector in close proximity to the base of the rearward surface. To effect unmating under a maximum predetermined separating force, the bifurcated end will deform or separate allowing the respective connectors to freely unmate.

Self sacrificing latching system

This invention relates to a latching system for a pair of intermatable electrical connectors, such as a plug and receptacle, which incorporates a mechanism for unlatching same by the application of a maximum predetermined separating force, such as may be the result of an accident, to the plug and receptacle. The system comprises a first electrical connector having a pair of flexible arms projecting axially therefrom, where the free ends of the arms include slot means for engaging complementary arms within the second electrical connector. The second electrical connector includes a forward ramp surface against which the flexible arms initially ride to effect mating of the connectors, a rearward surface slightly angled, i.e. on the order of about 4.degree. to 10.degree., from a base toward the ramp surface, and a metal spring arm mounted within the second electrical connector in close proximity to the base of the rearward surface. In the mated condition the spring arm engages the slot means. While a manually operated mechanism is provided to effect unmating, a safety system is included to prevent damage due to forces being applied thereto. For example, to effect unmating a maximum predetermined separating force may be applied therebetween causing the spring arm to flex to a position near the rearward surface at a critical release angle to thereby release the free end from its respective spring arm.
