Abstract

PURPOSE:To allow quick coupling and locking of connector by inserting a male connector into a female connector and fitting in place. CONSTITUTION:When the conductive contact rod 2a of a male connector 2 is inserted into the conduction hole 1a of a female connector 1, a metal sleeve 3 advances to push a slide sleeve 5 which then presses a spring 6. When the groove 4 in the metal sleeve 3 comes under a steel ball 9 fitted in a metal sleeve 7, the steel ball 9 drops into the groove 4 to release a cap nut 11. Consequently, the cap nut 11 is shifted to the position of a stopper 7b by means of a spring 8 and the steel ball 9 restricts the metal sleeve 3. At the same time, a lock metal 10 and the cap nut 11 are disengaged and the lock metal 10 is lifted by the repellency of the spring 13 thus locking the cap nut 11. This mechanism allows locking of the male and female connectors 2, 1 simultaneously with the electrical coupling thereof.
