Abstract: A novel male connector for an electrical connector assembly comprises an elastic housing which includes a recess for receiving the end of a female connector. When the male and female connectors are connected, a cavity is formed between the female connector and the recess of the male connector. Along the length of the recess, a rigid member is provided in the male connector which prevents the recess from stretching substantially when the male connector is disconnected from the female connector. Because the recess is prevented from stretching, the air pressure in the cavity between the male connector and the female connector remains relatively high during disconnection. The dielectric strength of the air in the cavity, which is a function of pressure, also remains high, so that the possibility of flashover is substantially eliminated.

Abstract: Improved insulator configurations are provided for retarding corrosion of the central conductor pin of a coaxial cable connector. In a first embodiment of the invention, the distal end of the dielectric which surrounds the pin is provided with a domed protuberance which deflects liquid away from the pin.

In a second embodiment, the dielectric is provided with a tubular extension portion which forms an insulator sheath around the central conductor pin, thus preventing bridging even when the connector is oriented vertically and the distal end of the outer body is submerged in liquid.
