An outer cable plug sleeve has a sealing ridge with a notch in it to allow interfacial air to escape during insertion and enter during extraction of the cable plug. A cable plug receptacle has a mating sealing groove which receives the sealing ridge covering the notch. A series of mutually engaging overlapping sleeves creates multiple air seals and a long path between an internal pin/contact electrical connection and an external shield plate ground on the plug. A split metal coupling nut slips over the cable and engages the shield plate and screws onto a threaded receptacle cylinder securing the previously coupled cable plug and receptacle together.

[ What is claimed is:] [1.] A high-voltage cable plug and plug receptacle device with a vented seal therebetween for electrically connecting a high voltage cable to a piece of high voltage equipment, wherein the device comprises:a high-voltage cable plug at an end of the high voltage cable, the cable plug having a first electrical connecting means and an outer sleeve having an air venting means in a first air sealing means;a high-voltage cable plug receptacle electrically connectable to the piece of high voltage equipment by an electrical equipment connection means, the plug receptacle having a second electrical connecting means for removably mating with the first electrical connecting means and a second air sealing means for mating with the first air sealing means and sealing the air venting means, so that air passes through the air venting means during insertion of the cable plug into the cable plug receptacle, thereby removing interfacial air between the cable plug and the cable plug receptacle, and air passes through the air venting means during disconnection of the cable plug from the plug receptacle, admitting air therebetween to make the disconnection easier, and when the cable plug and plug receptacle are fully connected a first air-tight seal is created between the first and second air sealing means and no air passes through the air venting means, the first and second air sealing means comprising a protruding sealing ridge and a mating sealing groove, positioned with one on the cable plug and the other on the receptacle so that when the cable plug and receptacle are fully connected, the sealing groove engages and covers the sealing ridge and covers the air venting means, and the air venting means comprises the sealing ridge provided with a notch therein, which said notch is covered by the sealing groove when the sealing ridge and sealing groove are mutually engaged.
