Spring lock type connector

Abstract

A spring lock connector has a male connector (M) with a cylindrical front receptacle (52) and a female connector (F) with a terminal accommodating portion (12) to be fit into the front receptacle (52) and on an outer peripheral side of the front receptacle (52). A spring (40) is mounted on the female connector (F) and spreads as the female connector (F) is connected to the male connector (M). The spring (40) includes engaging portions (43) arranged in an entrance path for the front receptacle (52). Guides (57) are provided on an opening edge of the front receptacle (52) and move onto the engaging portions (43) if a connecting operation is performed in proper connecting postures. Parts of the opening edge of the front receptacle (52) other than the guides (57) contact the engaging portions (43) to prevent connection if the connecting operation is performed in improper connecting postures.
