Title: Electrical connector short circuiting arrangements
Inventor: MINNIS ALAN JAMES
IPC: H01R13/52
Filed: 1991-05-10
Abstract: A bi-partite electrical connector (26) comprises a pin header part (30) and a receptacle part (32) comprising a receptacle housing (62) having rows of cavities therein each receiving an electrical receptacle terminal (64) crimped to an electrical lead (66). Pairs of the terminals (64) located in respective spaced pairs of the cavities have their leads (66) connected to electrically fired actuators of air bags of an automotive air bag system. The terminals (64) of each of these pairs of cavities are normally short circuited by means of a resilient short circuiting link (70) secured in a socket (82) between the cavities of each pair. This protects the air bag actuators against accidental firing as a result of spurious energisation of their leads (66), until the pin header part (30) and the receptacle part (32) have been substantially fully mated. As the pin header part (30) and the receptacle part (32) are moved together proximate to their fully mated position, actuator pins (38) projecting from the pin header part (30) depress the short circuiting links (70) to disengage them from the terminals engaged thereby, whereby the air bag actuators are connected in circuit. <IMAGE>
