ABSTRACT:
A separable electric connector for use "downhole" in the oil industry or else where when large pressure changes are encountered comprises a socket part which, prior to the assembly of the part, can be filled with a viscous insulating fluid. The corresponding plug part has a tubular member which is closed at one end and surrounds the socket part with a clearance when the connector is assembled. A male member which forms or carries contacts is upstanding from the closed end of the tubular member to enter the socket part and make the required contact or contacts. A passage is provided to allow flow of the fluid from the socket member into the space within the tubular member. A sleeve member subsequently enters the tubular member, whereupon the fluid flows mainly between the sleeve member and the tubular member until a seal is formed, for instance by a sealing ring. An escape path is formed, as between the socket member and the sleeve member, to allow the subsequent escape of excess fluid. In this way air is reliably purged from the spaces between the parts of the connector.
