1. An electrical connector comprising:
- mating first and second connector members;
said first connector member being provided with at least one electrically conducting pin extending therefrom;
said second connector member having means defining a cavity therein said cavity defining means including a movable element;
an electrical socket in said second connector member extending into one end of said cavity and being engageable with said pin when said connector members are mated;
a diaphragm closing the other end of said cavity, said diaphragm being penetrable by said pin during mating of said first and second connector members;
said cavity being filled with a semi-mobile nonelectrically-conducting compound; and
pressurizing means exposed to said cavity for automatically reducing the volume of said cavity to compensate for any loss of said compound from said cavity during normal usage of the connector, said pressurizing means including said movable element and resilient means biasing said movable element toward said cavity, said pressurizing means comprising a cylinder in said second connector member, said cylinder opening into said cavity, said movable element comprising a piston slidable in said cylinder; and
said resilient means biasing said piston in said cylinder toward said cavity.

Abstract
An electrical connector which can be safely used under water. The conductor pins of one-half of the connector are engageable with sockets in the other half of the connector. The sockets are disposed in a cavity filled with a semi-mobile compound. The pins pass through a self-sealing diaphragm before entering the cavity and engaging the sockets. Pressurizing means is provided in the cavity to compensate for any loss of the compound during usage of the connector.
