The connector device comprises a male plug and a female receptacle, each of which has a housing with a central tubular component and a cavity extending therethrough and adapted to receive an end of an electrical conduit. Both the plug and receptacle include means for aligning the electrical pathways therein and for sealing the conduits, plug and receptacle against elevated temperature and corrosive gases, etc. The central tubular components are electrically insulated. The male plug has a plurality of spaced parallel connector pins extending forwardly from the front end of the plug's tubular component and spaced inwardly of a plug sleeve. The receptacle tubular member is disposed within a sleeve and carries a pin receiver on the front end thereof, which receiver bears a plurality of spaced parallel passageways extending longitudinally of the tubular member and containing electrical connectors therein for interconnection with an electrical conduit at the rear of the female receptacle. The male plug sleeve is receivable within the female sleeve and sealing means in the male plug and female receptacle include spaced O-rings or equivalent graphite seals to provide double hermetic sealing protection. Moreover, the male plug connector pins sealingly engage the female receptacle passageways. Critical seal dimensions are obviated because the telescoping of the sleeves provides dynamic sealing of the device. Locking means are also provided to help hold the male and female components together. The device is simple, inexpensive, durable and effective.

Weatherproof hermetically sealed connector device

To prevent possible misalignment of the various parts of a plug and receptacle connector, if the coupling ring is inadvertently rotated before the receptacle is in full position, there is provided an interlock sleeve. This sleeve is spring-loaded and positioned between the coupling ring and the plug outer surface. Internal and external keys incorporated within the sleeve prevent inadvertent rotation of the coupling ring until the receptacle has made entry into the plug sufficiently to key both the coupling ring and plug shell.

Heavy-duty electrical connector

The invention is directed to a protective cover for the open face of the receptacle section of a multi contact electrical connector when the receptacle section and the plug section are not mated. The protective cover comprises a barrel and a cover plate closing one end of the barrel. Inside the barrel there is positioned a spring means so located that a disc placed over the spring means can be controllably moved longitudinally in said barrel to contact the end of said receptacle open face. At the outer end of said barrel are indexing means for polarized alignment with indexing means on said receptacle and locking means, for locked retainment of said cover to said receptacle socket.

Protective cover for electrical connector receptacle open end, providing

Connector for tow cable which carries tow tension and electrical circuits permits release of both the tension and the circuits. Electrical connectors in high current circuits are arranged so that the male connector is pulled out of the female electric socket, and the arc between them is elongated, but the arc chamber is closed until the arc is extinguished.
