Abstract

PROBLEM TO BE SOLVED: To miniaturize an electric connector with short-circuiting terminal, and minimize a short circuit releasing member insert hole by housing a short- circuiting terminal having a pair of back-to-back contact arms within a short- circuiting terminal housing cavity. SOLUTION: An electric connector 2 has a plurality of contact housing cavities 10 and a short-circuiting terminal housing cavity 18 for housing a short- circuiting terminal 20. The terminal 20 has a pair of back-to-back contact arms 22, 24 differed in elastic characteristic, so that an elastic contact state is held to upper and lower contacts 14 in the non-fitting of a partner contactor 4, and the contact arm 24 is separated form the contact 14 by a short circuit releasing member 48 in fitting with the partner contactor 4. Thus, the short circuit releasing member insert hole of the cavity 18 can be minimized to prevent the short-circuiting terminal from being twisted by the penetration of a tool, and the electric connector can be miniaturized.

By the way, the conventional short-circuiting terminal is provided with a pair of contact arms extending in parallel from the plate-like base, and the pair of contact arms is provided by the short-circuit releasing member provided on the mating connector when the mating connector is fitted. The contact arms of the same were simultaneously pulled away from the electrical contacts, thereby releasing the short circuit. Therefore, a large space for accommodating the short-circuit terminal is required in the connector housing, which has been an obstacle to miniaturization of the electrical connector with the short-circuit terminal.

Further, since the pair of contact arms of the short-circuit terminal are arranged back to back, one of the contact arms is always in contact with the electrical contact regardless of the mating or non-mating with the mating connector. The contact arm on the other side is formed as a large one with a large amount of bending, which is suitable for being displaced by the short-circuit release member provided on the mating connector. It is also possible to expect further improvement in the characteristics of the short-circuit terminal and miniaturization of the electrical connector with the short-circuit terminal.
