Guide post of electrical connector

摘要

A guide post (80) is adapted to be mounted to a first electrical connector for being received in a receptacle hole defined in a mating second connector to guide the mating operation of the connectors. The guide post has a threaded rear section (101) threadingly engaging with an inner-threaded hole defined in the first connector and a front section (102) extending beyond the first connector and insertable into the receptacle hole of the second connector. A hexagonal intermediate section (104) is formed between the rear section and the front section. A helical spring (20) having a first end supported on the intermediate section surrounds the front section and is retained thereon by a washer (30) which is movably fit over the front section and engages with a second end of the spring. A cap (40) is fixed to a free end of the front section to retain the washer thereon. The washer has a size greater than the receptacle hole thereby abutting against the second connector for compressing the spring, which in turn provides a buffering force between the two connectors.
