ABSTRACT:
An underwater electrical connector of the plug and receptacle type intended for use in environments characterized in having high or variable pressures, including a fluid-filled bladder that contains the receptacle and has a single port or a plurality of ports for receiving electrical probes. The chamber has a movable dielectric stopper and the ports comprise a seal having radially constricting force that forms a pressure-tight seal on the stopper. The probe is inserted into the seal, pushing the stopper to a retracted position with the seal forming a pressure-tight seal on the probe. The chamber has a plurality of innerconnecting dielectric bath chambers with a wiping seal positioned therebetween, for bathing and wiping the stopper and the probe as the probe moves against the stopper to the electrical contact position. This also provides a single chamber with two wipers. The bath chambers comprise a single chamber with fluid flow therethrough to replenish and condition the dielectric fluid in the respective bath chambers. This fluid flow is around the stopper or through channels within the stopper. An electrical connection of more than two circuits is provided by a single probe in a manner that insures the integrity of the electrical connection while reducing or eliminating damage to seals and the receptacle connectors through movement of a multiple contact probe.
