Abstract
Abstract A plug-receptacle electrical connector is disclosed incorporating a positive-engagement coupling with a locking apparatus. The plug includes a body with an integral transversely-extending strap which is folded to a hinging position along a surface of the body to receive a latch bar on the receptacle, for a positive engagement. A coil helper spring is mounted under the hinge strap, for maintaining engagement with the latch bar and additionally to support a locking cam which may be rotated to lock the hinge strap in a raised position of engagement with the latch bar.
