Double-layer oil bag type deep sea pluggable electric connector

The invention discloses a double-layer oil bag type deep sea pluggable electric connector, comprising the fact that a double-layer oil bag is fixed by a jack assembly through a front end shaft sleeve and a rear end shaft sleeve; two sealing interfaces are formed by a sealing piston rod and the double-layer oil bag, so sea water is prevented from entering a jack cavity, water body isolation and electrical insulation effects are realized, moreover, the internal and external pressure difference is reduced, a sealing demand is reduced, and a product is guaranteed to work in a deep sea environment for a long time; when a pin assembly matches the jack assembly, a pin conductor resists against the sealing piston rod and pushes the piston rod together with the pin conductor into an oil cavity until the pin conductor and a jack conductor are switched on; and in a matching process, a front side external oil cavity composed of the front end shaft sleeve and a filter ring is used for absorbing and holding foreign matters. The double-layer oil bag type deep sea pluggable electric connector is reliable in sealing, simple in operation and relatively low in plugging force; the oil bag is prevented from being eroded and destroyed by impurities such as sand grains through adoption of a special sand storage cavity, the service life is greatly prolonged, and deep sea plugging and conduction functions are realized.
