Abstract:
An improved pressure compensated electrical plug connector having a socket part for receiving at least one contact pin of a plug part, the socket part including a casing having at least one female contact and a front plate mounted to the casing, the front plate having at least one opening formed therein in axial alignment with the at least one female contact, a number of the at least one contact pin corresponding to a number of the at least one opening and the at least one female contact, each at least one contact pin inserting through each at least one opening in the front plate and into each at least one female contact, the casing having at least one pressure compensating bore for compensating a pressure between an inner space of the casing and an environment in which the plug connector is located, the casing further having a membrane separating the inner space from an outer space, the outer space communicating with the at least one pressure compensating bore, the inner space filled with a non-conducting fluid and surrounding the at least one female contact, the at least one female contact having a sealing sleeve and a front contact support, the at least one female contact enclosing a sliding piston displaceable within a space defined by the at least one female contact, a diameter of the at least one female contact corresponding to a diameter of the at least one contact pin, the improved pressure compensated electrical plug connector further having a spring mounted within the space defined by the at least one female contact for moving the sliding piston in a direction towards the at least one opening when the spring is in a non-compressed state, the improvement comprising:a) an outlet valve positioned intermediate the sealing sleeve and the front contact support for closing off the space defined by the at least one female contact from the inner space filled with the non-conductive fluid when the improved pressure compensated electrical plug connector is in an unplugged state; b) the outlet valve opening the space defined by the at least one female contact to the inner space filled with the non-conductive fluid when the improved pressure compensated electrical plug connector is receiving the at least one contact pin; c) an inlet valve positioned in a distal area of the at least one female contact providing an opening to the inner space filled with the non-conductive fluid from the space defined by the at least one female contact when extracting the at least one contact pin from the at least one female contact thereby allowing an afterflow of fluid into the space defined by the at least one female contact; and d) a separating system located intermediate the inner space of the casing and the inlet valve.
