Abstract
The utility model provides a cable joint, which comprises a hollow joint main body and an outer semiconductor shielding layer, wherein the outer semiconductor shielding layer is formed on the outer surface of the joint main body; and the two ends of the joint main body are provided with stress cones. The utility model has the beneficial effects that: an outer semiconductor shielding layer 2 is formed for realizing outer shielding, so that air gap discharge between insulating layers is avoided, and the outer semiconductor shielding layer 2 is taken as a low-voltage electrode; the cable joint is arranged in a prefabricated way without firing or expanding operation, so that easiness and practicability are achieved; the phenomenon of expanding mark on the inner wall of the main body during expanding is avoided, and the electric performance of the main body is not influenced; and meanwhile, a main body part is made of an elastic material, so that the cable joint can adapt to cables of different inner diameters, and has a good sealing effect.
Description
Technical field
The utility model relates to electric cable fitting, relates in particular to a kind of cable joint.
Background technology
Current, electric energy has become energy form main among social production and the human lives.The transmission of electric energy be unable to do without power cable, simultaneously, the electric cable accessories supporting with it, its effect also can't neglect.As the insulating joint of one of annex, undertaking the vital task that connects the two ends power cable, its quality that connects effect directly influences the efficient of electric energy transmitting.
But insulating joint field fabrication; its process relates to cutting, cleaning, the crimping of core; the baking installation of heat-shrinkable T bushs such as stress control tube, inside and outside insulated tube, semiconductive pipe and the installation of copper shield net; and the winding of protective material, welding etc., complex procedures and require very high to construction level.
Therefore, need simple, the widely applicable insulating joint of a kind of installation process.
Summary of the invention
In order to solve the problems of the prior art, the utility model provides a kind of cable joint.
The utility model provides a kind of cable joint, and described cable joint comprises the hollow joint main body, partly leads screen outward, describedly outer partly leads the outer surface that screen is arranged on described adapter body, and described adapter body two ends are provided with stress cone.
As further improvement of the utility model, described stress cone and described adapter body design for integral type.
As further improvement of the utility model, the stage casing of described adapter body is provided with the shielded-plate tube around its hollow space.
As further improvement of the utility model, described shielded-plate tube and described adapter body design for integral type.
As further improvement of the utility model, also comprise metal screen layer, described metal screen layer is overlying on the described outer appearance of partly leading screen.
The beneficial effects of the utility model are: external shield has increased the outer screen 2 of partly leading, and no breath discharge between assurance and the insulating barrier is as low-field electrode.This cable joint adopts the prefabricated mounting means when mounted, and whole process need not to get angry and carries out dilation procedure, and is simple.Main body inner wall does not produce and expands the trace phenomenon in the time of so can not having expansion yet, can not have influence on the electric property of main body.Simultaneously, because main part adopts elastomeric material, therefore can adapt to the cable of different inner diameters, and have good sealing effectiveness.
Description of drawings
Fig. 1 is the structural representation after a kind of cable joint of the utility model and cable are connected.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is further specified.
As shown in Figure 1, a kind of cable joint, described cable joint comprises hollow joint main body 1, partly leads screen 2 outward, describedly outer partly leads the outer surface that screen 2 is arranged on described adapter body 1, described adapter body 1 two ends are provided with stress cone 3,4.Described stress cone and described adapter body 1 design for integral type.The stage casing of described adapter body 1 is provided with the shielded-plate tube around its hollow space, and described shielded-plate tube 5 designs for integral type with described adapter body 1.Also comprise metal screen layer 6, described metal screen layer 6 is overlying on the described outer appearance of partly leading screen 2.
Described adapter body is made through high temperature vulcanized by liquid silastic.Described stress cone is made by the liquid silastic cooling.Described adapter body manufacture craft is to lead partly outward earlier that to be contained in together behind screen and stress cone, the stress control tube sulfidization molding in the die cavity with the electrically insulating silicone rubber sulfidization molding be one.This technology can be increased work efficiency greatly, and the stability of product is also better, and is more safe and reliable.
In addition, this cable joint also comprises: long copper sheathing 11, coaxial cable 12, short copper sheathing 13, semi-conductive tape 14, self-adhesion insulating tape 15, ward off plumbous 16, adhesive waterproof tape 17, glass fibre reinforced plastics casing 18 and pyrocondensation protecting pipe 19.
In installation process, at first will need the core 7 of two crosslinked cables connecting and 8 one of them (for example 7) to penetrate the utility model conductor connecting tube 9; Again with after the core 7 and 8 crimping of two crosslinked cables and installing conductor connecting tube 9, radome 10 is covered on outside the conductor connecting tube 9, the utility model full chilling shrink crosslinked cable insulation joint is moved to radome 10 places according to anchor point, and shielded-plate tube 5 is surrounded radome 10 fully.Joint produces powerful radial pressure like this, two cores 7 and 8 is packed tightly, and packed tightly by the radome 10 of shielded-plate tube 5 with core, guarantees to be connected with the effective of joint shielded-plate tube, and guarantees equipotential, also has good sealing effectiveness.
The utility model full chilling shrink crosslinked cable insulation joint adopts the prefabricated mounting means when mounted, and whole process need not to get angry and carries out dilation procedure, and is simple.Main body inner wall does not produce and expands the trace phenomenon in the time of so can not having expansion yet, can not have influence on the electric property of main body.Simultaneously, because main part adopts elastomeric material, therefore can adapt to the cable of different inner diameters, and can produce good sealing effectiveness.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
