A kind of hard conductor unjacked cable of single with termination, including cable, termination, which is characterized in that The cable includes single conductor, which, which successively drapes over one's shoulders, insulating layer, braiding layer, protective layer, and the insulating layer includes Layer of silica gel, polyvinyl chloride layer, the protective layer include flame-retardant layer, waterproof rubber layer, and the termination includes wiring cylinder, should The inside of wiring cylinder is successively arranged conductor bores, insulating layer hole, braiding layer hole, protective layer hole, the conductor bores, insulating layer hole, Braiding layer hole, protective layer hole central axis uniformly the wiring cylinder central axis be overlapped, the aperture of the conductor bores with The diameter of the hard conductor of single is adapted, the insulating layer hole, braiding layer hole, protective layer hole aperture respectively with the insulation Diameter when layer, braiding layer, protective layer are draped over one's shoulders by the hard conductor of the single is adapted, the conductor bores, insulating layer hole, braiding Layer hole, protective layer hole are sequentially connected logical, and it is equal that the binding post corresponds to the insulating layer hole, braiding layer hole, the section in protective layer hole Annular groove is offered, ball grooves are offered on the annular groove, ball is equipped in the ball grooves, is arranged with pressure on the annular groove Fixed ring, the annular groove are equipped with limiting section close to the section of the ball grooves, are arranged with holddown spring on the annular groove, institute Compression lantern ring is stated to abut against with the holddown spring.

In the present invention, the outside wall surface that the wiring cylinder corresponds to the conductor bores is equipped with fixed plate, this is fixed Plate is equipped with threaded hole.

In the present invention, the bottom face that the annular groove and the holddown spring abut against is equipped with raised brim.

In the present invention, insulation sleeve is arranged in the conductor bores.

Implement the hard conductor unjacked cable of this single with termination in the utility model, has beneficial below Effect: the penetralia of cable is layer of silica gel, and layer of silica gel not only has preferable insulation effect, it may have good heat resistance, it can The difference variation of appropriate cable；Braiding layer has good stretch resistance energy, and protective layer outermost layer the most can protect cable Not by erosion by wind and rain；Termination is adapted with the hierarchical structure of cable, using wiring cylinder as stress cylinder, successively adds insulation Layer, braiding layer, protective layer, by the tenesmus stress that cable generates when hanging allow it is each drape over one's shoulders tegillum and respectively undertake, avoid stress from concentrating In a certain level, cause the level damaged.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe.

The hard conductor unjacked cable of this single with termination as shown in Fig. 1 to Fig. 8, including cable 100, wiring Device 200, cable 100 include single conductor 1, which, which successively drapes over one's shoulders, insulating layer 11, braiding layer 12, protective layer 13, Insulating layer 11 includes layer of silica gel 111, polyvinyl chloride layer 112, and protective layer 12 includes flame-retardant layer 121, waterproof rubber layer 122, wiring Device 200 include wiring cylinder 2, the inside of the wiring cylinder 2 be successively arranged conductor bores 21, insulating layer hole 22, braiding layer hole 23, Protective layer hole 24, wherein conductor bores 21, insulating layer hole 22, braiding layer hole 23, protective layer hole 24 the uniform binding post of central axis The central axis of body 2 is overlapped, and the aperture of conductor bores 21 is adapted with the diameter of the hard conductor 1 of single, insulating layer hole 22, braiding layer hole 23, straight when the aperture in protective layer hole 24 is draped over one's shoulders with insulating layer 11, braiding layer 12, protective layer 13 by the hard conductor 1 of single respectively Diameter is adapted.

Conductor bores 21, insulating layer hole 22, braiding layer hole 23, protective layer hole 24 are sequentially connected logical, form stairstepping to each other Formula is connected, the corresponding insulating layer hole 22 of wiring cylinder 2, braiding layer hole 23, protective layer hole 24 section offer annular groove 25, should Ball grooves 26 are offered on annular groove 25, and ball is equipped in ball grooves 26, is arranged on annular groove 25 and compresses lantern ring 27, annular groove 25 are equipped with limiting section 28 close to the sections of ball grooves 26, and holddown spring 29 is arranged on annular groove 25, lantern ring 27 is compressed and compresses Spring 29 abuts against.

In the above-mentioned this cable of application, only each tegillum that drapes over one's shoulders of cable head-end need to successively be stripped out and each layer of hole phase The length of adaptation so that cable head-end be integrally formed with termination inside it is compatible step-like, then will compress lantern ring under Pressure protrudes into cable easily in binding post body, then pushes back lantern ring is compressed on position corresponding with ball grooves, Under the pressing force of ball, so that the every aspect of cable tightens together with wiring cylinder；With existing cable interconnection technique It compares, what such cable type of attachment can allow other than internal lead body each drape over one's shoulders tegillum and respectively undertake under cable Stress is fallen, conductor thread core is avoided to go to undertake stress.

The outside wall surface of the corresponding conductor bores 21 of wiring cylinder 2 is equipped with fixed plate 30, which is equipped with threaded hole 31.When After wire core connects, fixed plate is fixed in equipment by screw, wiring cylinder can be fastened, avoid binding post Body loosens.

The bottom face that annular groove 25 and holddown spring 29 abut against is equipped with raised brim 32.It is arranged in conductor bores 21 absolutely Edge set 33.The setting of raised brim 32 can preferably constrain the compression of holddown spring, and being equipped with insulation sleeve in conductor bores can keep away Exempt from conducting wire and drain conditions are generated by wiring cylinder.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, made any modification, equivalent replacement and improvement etc. should be included in the utility model Protection scope within.
