Technical field
The utility model belongs to cable plug part security technology area, and what be specifically related to is a kind of integral type power cable plug part.
Background technology
In electric power distribution engineering, the connection of cable end piece all will use plugging member, power cable end is needed to be connected prefabricated shaping with plug part, existing plugging member connects with cable all will have stress cone to do middle transition and mating reaction, as shown in Figure 1, 2, stress cone 1 is made up of stress cone insulating barrier 1-1 and stress cone conductive layer 1-2, plugging member 2, stress cone 1, crimp type terminal 3, cable are assembled complete in actual applications, connect and indirect component stress cone, easily occur packing problem owing to there is second time; The application of stress cone in power cable plug part, can increase the volume of plug part, and the length of plug part all can increase with the diameter matched; In actual production, accessory product is many, and the production cycle is long, can increase labour intensity, increases adult; Secondary installing also can reduce the fail safe of electric power system in actual motion, and these problems still await technological innovation and solve.
Summary of the invention
In order to solve the problem, the utility model provides a kind of integral type power cable plug part.
The technical scheme that the utility model provides is: integral type power cable plug part, comprise a T-shaped hollow insulation threeway, insulation threeway is formed by the vertical cylinder that insulate is crossing with in the middle part of insulation straight tube, it is characterized in that insulation threeway has been nested with a hollow conductive threeway, by conducting electricity, vertical cylinder is crossing with in the middle part of conduction straight tube to be formed in conduction threeway, this conduction cylinder that hangs down is a flat hole parallel with straight tube port surface with conduction straight tube crossing endoporus of holding, along concordant with insulation straight tube inner face in conduction straight tube two ends, the conduction threeway cylinder internal diameter that hangs down is equal with the vertical cylinder internal diameter of insulation, the vertical cylinder free end external diameter of insulation reduces the tapered termination of formation one gradually, conduction cylinder free end and the insulation cylinder external diameter that hangs down that hangs down starts to reduce and locates radial direction and maintain spacing, screen is provided with outside insulation threeway, screen forms the internal diameter annular canister equal with the vertical cylinder internal diameter of insulation outside being hung down in the tapered termination of cylinder in insulation, screen is externally connected with earth terminal, a crimp type terminal is provided with in the vertical cylinder of insulation, conduction straight tube is inserted in crimp type terminal one end, other end crimping lead wire.
Further, described insulation straight tube internal diameter by middle part to two ends gradually expanding formed horn-like.
Further, described screen is connected with test point.
Further, described screen wall thickness thickeies gradually to the vertical tapered termination of cylinder of insulation.
Further, described insulation straight tube one end is provided with insulating plug.
The technical program stress cone is one-body molded on plugging member, need not produce stress cone separately, reduce workload reduce cost, also can avoid secondary assemble produce along face creepage phenomenon; Applied stress cone can not make this plug part volume less, and it is more convenient to install, and it is larger that insulation hangs down that the insulation thickness of cylinder can do, coefficient of safety higher guarantee system effective long time operation, the utility model is simple for structure, reasonable, is suitable for applying.
