Fig. 3 is the sleeve structure cutaway view of a kind of plug-in cable termination of the utility model Stress Control body.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As shown in Figure 1-Figure 3, a kind of plug-in cable termination Stress Control body mainly is made up of conical section and sleeve portion, is cavity structure in the middle of cone and the sleeve pipe.Described conical section comprises high-tension shielding layer 1, insulating body 3 and the low pressure screen 2 that is fixedly connected sequentially together; Described sleeve portion comprises ground shield 4 and the insulator 5 that is fixedly connected sequentially together; Cavity in the middle of the described cone is a conical cavity.
As a specific embodiment, the ground shield 4 of the high-tension shielding layer 1 of above-mentioned conical section, low pressure screen 2 and sleeve portion is conductive rubber material and makes, and above-mentioned cone insulating body 3 and sleeve insulator 5 are the electro-insulating rubber material and make; Be fixed together by the sulfuration process combination between described high-tension shielding layer 1, low pressure screen 2 and insulating body 3 these three parts, also be fixed together between described sleeve pipe ground shield 4 and insulator 5 two parts by the sulfuration process combination.The profile of insulating body 3 is a pyramidal structure, and itself and high-tension shielding layer 1 adjacent part are small end, is to hold greatly with low pressure screen 2 adjacent parts, forms a step in insulating body 3 and low pressure screen 2 junctions.Low pressure screen 2 is arranged to beveled end and is fixedlyed connected with insulating body 3 bottoms in the part of cone cavity, is provided with the step that cooperatively interacts with described ground shield 4 at low pressure screen 2 inner chambers.Fixedly connected with insulator 5 by an oblique angle in the upper end of described ground shield 4, the step that cooperatively interacts with described low pressure screen 2 is arranged in ground shield 4 outer setting.When cable termination Stress Control body is installed, can determine whether installation puts in place by these steps.
The utility model in actual applications, its installation method is: at first, sleeve pipe is inserted in to power transmission cable, and then conical section is inserted in to sleeve body, last, single piece is loaded in other access device parts.After the Stress Control body was in place, the lower surface that sleeve insulator 5 upper surfaces surpass cone high-tension shielding layer 1 is 2mm at least, to guarantee better electric field shielding effect.Sleeve pipe ground shield 4 upper surfaces can not surpass the linea angulata that rises of cone low pressure screen 2 beveled end, and the beveled end upper surface of described sleeve pipe ground shield 4 and the rising between the linea angulata bottom of cone low pressure screen 2 beveled end that cooperatively interacts are left the distance of 2mm at least, to prevent that electric field from strange the change being taken place in the cooperation place, influences the electric field shielding effect of product integral body.
After the utility model adopts said structure, because the cavity in the middle of the cone is a conical cavity, both having helped cable plugs easily, the cable access that can guarantee this cable termination Stress Control body adaptation different cross section specification again also matches with it, increased the versatility of Stress Control body, thereby reduced the mfg. moulding die kind of the cable termination Stress Control body product correspondence of manufacturing enterprise, and reduced finished product stock quantity in stock, stock cost and production cost have been reduced, and reliable in structure is installed simple, convenient.
