Abstract
A high voltage electrical cable separable connector module comprises an internal gas flow-restricting gasket to restrict an undesirable flow of ionized arc-generated gases from the module upon live disconnection of the module from an electrical circuit. By restricting the flow of ionized gas in the module, its arc interrupting capability is enhanced, and at the same time, the risk of an arc restrike upon disconnection is appreciably reduced.
Claims10
A separable connector module for connecting electrical power distribution cable, the module being of the type including:
- an insulating housing having an open contact-receiving passageway therein extending from a first end of said housing a predetermined distance into said housing and terminating in a gas expansion chamber;
- a hollow, cylindrical, bore sleeve telescopingly fit inside said passageway of said housing;
- an electrical contact member inside said passageway and rigidly fixed to said bore sleeve, and a gas activated piston for moving said bore sleeve along said passageway, said piston being disposed in said chamber and having an opening through which gases generated in said passageway by arcing from said contact member can pass from said passageway into said chamber,
- wherein the improvement comprises a resilient gasket in the space between the bore sleeve and the inside wall of said passageway for preventing escape of arc-generated gases to the outside through that space.
