Socket for turn-and-lock multipin electrical device

Abstract

An electrical device having a base from which extend two parallel connector pins each having a small-diameter shank and a large-diameter head is fittable with a socket having a housing formed with a transverse wall having front and back faces and having between the faces a predetermined thickness substantially less than a distance between an end face of the device and the heads. The wall is formed with a pair of throughgoing slots each having a wide end through which a respective one of the heads can pass and an opposite narrow end so that the device can be fitted to the housing by passing the heads of the pins through the wide ends until the device end face engages the wall front face followed by turning of the device to displace the heads toward the narrow ends of the respective slots. A respective ramp at each of slots adjacent the respective narrow end is engageable with an underside of the respective head and is angled such that, on movement of the respective pin toward the respective narrow end, the respective head is cammed backward away from the wall back face and the device end face is pressed against the wall front face. Respective electrical contacts on the housing at the slots engage the heads of the respective pins when same are at the narrow slot ends.
