Abstract

An electrical connector device has a slot or opening therein for receiving an end portion of an electric current carrying line such as a conductor cable, wire or bus bar and, on such insertion, engage and push-back a slidable, piston-like, slidable control valve element against forwardly pressing spring-loading thereon to apply fluid pressure to and activate a clamping plunger-like latching element. The latching element engages and clamps the conductor end portion against a wall portion of the device in an efficient, electrical connecting relation within the device. Fluid, such as air under pressure may be applied continuously to the device and may, in accordance with one aspect of the invention, be continuously exhausted until an electric line is inserted for connection therein. A push-in element or plunger enables a quick release of fluid pressure and a corresponding quick release of the electric line when it is to be detached from a tight, electrically-efficient, clamping connection within the device.
