Described bonding conductor one end is socketed on in the inside semiconductive layer of described rear plug device, and the inside semiconductive layer of the other end and described front plug device also connects.
Described front and back plug device is made up of liquid silicon rubber material, adopts liquid silicon rubber material, has excellent anti-flammability, explosion-proof, resistance to soiling, uvioresistant, ageing resistance and sealing, substantially increase safety in utilization.
Because the utility model is by arranging front plug device and rear plug device, make described front plug device and the grafting separably of rear plug device, the utility model is had and installs and dismantle quick, easy advantage, convenient for maintaining personnel carry out Fast-Maintenance wiring equipment; In addition, owing to being all coated with an inner semiconductive layer in the middle part of the inwall of described front plug device and rear plug device, the outer wall of described front plug device and rear plug device is coated with an outside semiconductive layer all completely, and stress cone is formed on front plug device and rear plug device inside cavity in advance, this structure improves the plug-in device of prior art when loop-network switch cabinet works, surface produces the situation of charge inducing, when recovery cable, the utility model can be extracted neatly from loop-network switch cabinet or insert, facilitate breakdown maintenance, also improve electrical safety simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of separable connector described in the utility model.
Fig. 2 is the structural representation of the front plug device of the utility model plug-in and rear plug device.
Embodiment
For describing technology contents of the present utility model, structural feature, the effect that realizes in detail, below in conjunction with execution mode
And coordinate accompanying drawing to further illustrate.
As Fig. 1, a kind of separable connector shown in Fig. 2, primarily of front plug device 1, rear plug device 2, bonding conductor 3, stress cone 4 is formed, described front plug device 1 and rear plug device 2 are the T-shaped cavity of hollow, rear plug device 2 is plugged in front plug device 1 cavity, front plug device 1 and rear plug device 2 are by internal layer, middle level and outer totally three layers of different silastic material is prefabricated forms, described bonding conductor 3 is located in the horizontal cavity of rear plug device 2, bonding conductor 3 two ends are provided with connector and are fixedly connected with front plug device 1 and rear plug device 2, described stress cone 4 is formed on front plug device 1 and rear plug device 2 inside cavity in advance.Described front plug device 1 and rear plug device 2 are silastic material and make, and utilize silastic material to make and can ensure the accurate cooperation of coupling part and make its inside be in sealing state, thus have excellent waterproof and anti-static effect.Described stress cone 4 is formed on front plug device 1 and rear plug device 2 inside cavity with front plug device 1 and rear plug device 2 in advance by injection moulding integrated molding, structure is simple, can uniform electric field stress effectively, be convenient to install and dismounting, improve the operating efficiency of in-site installation and maintenance.
