More specifically, an inboard fixedly sleeved conductive metal pipe of described Plug Division, an end of described conductive metal pipe are socketed in the inside semiconductive layer with described back plug device, and the other end also connects with the inside semiconductive layer of described preceding plug device.Described conductive metal pipe is the induction field of shielded type cable terminal generation further, and be connected the inside that makes described back plug device and preceding plug device with described inner semiconductive layer and realize shielding fully, further improve shield effectiveness, make to the utlity model has higher fail safe.
Further, described conductive metal pipe is aluminum pipe.Utilize described aluminum pipe to make shield effectiveness of the present utility model better.
Particularly, described outside semiconductive layer stretches out in the end face of described first socket part.When described first socket part was pegged graft into other jockeys, the outside semiconductive layer that stretches out the described first socket part end face can be coated on other jockeys, thereby further improves fail safe of the present utility model.
Preferably, plug device and back plug device are the silicon rubber material and make before described.Utilized the silicon rubber material to make can to guarantee first socket part, the second socket part interference fit precisely, after connection, make inside be in sealing state, the utlity model has good waterproof and flood control results thereby make.
Because the utility model by preceding plug device and back plug device are set, pegs graft described preceding plug device and back plug device separably, make the utlity model has and install and dismantle fast, easy advantage, thus the convenient for maintaining personnel keep in repair wiring equipment fast; In addition, because the inwall middle part of plug device and back plug device all is coated with an inner semiconductive layer before described, the outer wall of plug device and back plug device all is coated with an outside semiconductive layer fully before described, therefore, two semi-conductive layers have the good shield effectiveness of generation, improved the plug-in device of prior art effectively when loop-network switch cabinet is worked, the surface produces the situation of charge inducing, thereby when recovery cable, the utility model can be extracted from loop-network switch cabinet chargedly or inserted, make things convenient for breakdown maintenance, also improved electrical safety simultaneously.
Description of drawings
