CONNECTOR OF ELECTRICAL CIRCUITS Russian patent published in 1999 - IPC

FIELD: power production, in particular, commutation equipment for vehicles and ground power supply stations. SUBSTANCE: device has plug and socket, which have housings, insulators, contact pins and sockets respectively. In addition device has device for relative orientation of guiding pins and respective guiding channels. Said device for relative orientation has contact indication unit, which has adjustment screws which are spring-loaded with flexible members, and are connected to indication equipment, which are connected to power supply through switch. One screw contacts guiding pin and is passed through current-conducting washer, which is also connected to indication equipment. Second screw is spaced with respect to another grounded guiding pin. Current-conducting sleeves of socket contain current-conducting plates, one of which is grounded. This conforms to condition of difference in lengths of guiding pins and contact pins. EFFECT: increased reliability of automatic connection. 2 dwg
