Abstract
The utility model relates to a cold-retracting plug-in type cable connecting terminal which comprises an outer sleeve and a stress body, wherein the outer sleeve forms an inverse T shape, the upper part of the outer sleeve is provided with a cylindrical end matched with the stress body, and the inner wall of the end is provided with supporting strips of a cylindrical rotary disc; the stress body forms a cylindrical shape, and the inner wall of the stress body is also provided with supporting strips of the cylindrical rotary disc. The interface performance of the utility model is greatly improved through the elasticity of silicon rubber, the expansion functions of the supporting strips and the fit of the outer sleeve and the stress body so that the utility model has more convenient installation, and the fit of the cable connecting terminal and the cable is a wide-aperture fit; the cable connecting terminal with one specification can be applied to a plurality of sections of one voltage level so that the manufacture and maintenance cost of a mould is saved, and the labor productivity is enhanced.
Description
Technical field
The utility model relates to a kind of cable connecting terminal, especially a kind of cold retracting plug-in type cable connecting terminal that is widely used in 10KV ring main unit switch cubicle turnover line.
Technical background
Traditional plug-in cable connectors is prefabricated plug-in cable connectors, it is the insulator with cable termination, inner shield and external shield are made into a complete prefabricated component cable connectors in advance in factory, its advantage is that the cable conductor junction has an inner shield structure, the problem of intractable such as conductor junction electric field distortion and cable insulation axial shrinkage and cutting cable reagency awl has all been avoided, its weak point is that the prefabricated cable connector is one to one with cooperating of cable basically, promptly specification product only is applicable to a cross section cable of an electric pressure, therefore specification is many, mfg. moulding die is also many, insulating barrier outside dimension to cable requires high simultaneously, the common magnitude of interference is at 2-5mm, also be the diameter of bore 2-5mm that the cable insulation external diameter is greater than cable connectors, the magnitude of interference is too small, cable connectors will break down, and the magnitude of interference is excessive, and the connection of cable is difficulty very, easily produce air gap in addition, various electric accidents take place.
Summary of the invention
The purpose of this utility model provides a kind of being fit to the multiple line of a kind of electric pressure footpath cable, the cold retracting plug-in type cable connecting terminal that need not special-purpose thermal source and instrument simple in structure, easy for installation.
For realizing above purpose, cold retracting plug-in type cable connecting terminal of the present utility model comprises overcoat and stress solid, described overcoat is shape, to be the columnar end that cooperates with stress solid with the place of connection between the bottom be provided with on its top is used for cylindrical ends, the end inwall is provided with the support bar that cylindric dish changes, stress solid is cylindrical, and its inwall also is provided with the support bar that cylindric dish changes.
Be that the support bar that described cylindric dish changes is that the plastic strip dish commentaries on classics welding back that will extrude forms cylindric.
Described stress solid internal face is embedded with the stress cone that an end stretches to the stress solid outside wall surface.
The utility model utilizes the elasticity of silicon rubber and the dilating effect of support bar, and the cooperation of overcoat and stress solid, the interface capability of product is greatly improved, make its installation more convenient, and it is that wide aperture cooperates with cooperating of cable, the product of a specification has been saved the manufacturing and the maintenance cost of mould applicable to a plurality of cross sections of an electric pressure, has improved labor productivity.
Description of drawings

Fig. 2 is the structural representation of stress solid in the utility model.
Embodiment
As shown in the figure, cold retracting plug-in type cable connecting terminal of the present utility model comprises overcoat 1 and stress solid 2, overcoat 1 shown in Figure 1 is shape, its top is cylindrical ends 1-1, the bottom is columnar bottom 1-2, the end is provided with the place of connection between the bottom and is used for the bayonet socket 1-3 that the metal connector patches, the skin of overcoat 1 is that the rubber-like silastic-layer is made up of electrically insulating silicone rubber layer 1-4 and conductive silicon rubber layer 1-5, the inwall of overcoat end 1-1 is provided with the support bar 1-6 that outer silicon rubber expansion is come, and described support bar 1-6 is that the strip plastics that will extrude are welded into cylindric through ultrasonic wave or infrared ray coiling.Stress solid 2 shown in Figure 2 cooperates with the end 1-1 of overcoat 1, stress solid 2 is cylindric, cylindrical shell 2-1 also is a rubber-like silicon rubber, it is the stress cone 2-2 of material that its cylinder inboard wall face is embedded with the conductive silicon rubber, the end of stress cone 2-2 extends to the outer wall of cylindrical shell, and the stress solid inwall also is provided with the cylindric support bar 2-3 that the silicon rubber expansion is come.When installing and using, earlier cable and metal connector are entangled with stress solid 2, spur support bar 2-3 then, stress solid 2 shrinks just can be fastening with both, they inserted the end 1-1 of overcoat again, pulls out the support bar 1-6 of overcoat end, installs promptly to accuse and finish.
Cold retracting plug-in type cable connecting terminal of the present utility model can be at no-voltage, have voltage zero load and have voltage to have load to plug operation under three kinds of situations.It also can be widely used in the loading amount of 10KV ring main unit switch cubicle turnover line terminal, cable distribution box and box-type substation etc.
