ABSTRACT:
An electrical plug connector of the quick disconnect type for high-voltage applications. The plug connector is matable with a receptacle connector having a tubular-shaped outer wall, a central cavity, and an electrical contact extending into the cavity from the base of the receptacle connector. The plug connector comprises an elastomeric, dielectric connector body which includes an inner central body portion and an integral, tubular-shaped, outer body portion spaced from and coaxially extending therealong defining an axially extending annular cavity therebetween. When the plug and receptacle connectors are mated, the tubular-shaped outer wall of the receptacle connector extends into and fills the annular cavity of the plug connector entering into an elastic gripping condition with at least said outer body portion and preferably with the inner body portion as well, forming broad outer and inner bands of air-free sealing engagement and causing air to be displaced from the annular cavity and creating a vacuum in the annular cavity. The vacuum and elastic gripping are sufficient to prevent inadvertent separation of the connectors, yet permits the connectors to be easily separated when desired by simply pulling them apart. The connector also provides an improved electrical seal by providing a voltage leakage path of increased length at the interface between the mated connectors. In one embodiment of the invention, the plug connector comprises a "dummy" connector usable as a seal plug for unused receptacle connectors and having a blind pin-receiving opening extending thereinto.
