Abstract

A single core cable shielding type separable connector comprises a connector body and a stress cone. A main cable channel and an auxiliary cable channel which are communicated with each other are formed on the connector body. The connector body comprises a voltage sharing layer, an insulating layer and an outer shielding layer which are integrated from inside to outside. The stress cone sleeves the exposed part of a cable connecting end and mounted in the auxiliary cable channel. A cable protecting layer protector is connected with the exposed part of a cable. The stress cone is disposed in the inner wall of the insulating layer and insulated from the outer shielding layer. The single core cable shielding type separable connector has the advantages that by modifying the structure of the outer shielding layer or the stress cone, the outer shielding layer of the connector body is allowed not to be connected and communicated with a cable shielding layer; strong overvoltage or inductive voltage is evacuated by the outer shielding layer of the connector body and the cable protecting layer protector, burning and punch-through are avoided, grounding fault is avoided, normal operation and high safety and stability of a power system can be guaranteed, and the like.
