Abstract
The utility model relates to a high tension cable joint, which consists of pins, a metal pipe, a rubber core, a cable wire and a shell. The center of the rubber core is a needle groove; the rear of the pin is arranged in the needle groove of the rubber core; the core wire of the cable wire is welded with the rear of the pin; the ground wire of the cable wire is welded with the metal pipe; the shell is sleeved on the rubber core and the metal pipe; the rear of the pin has anti-rotary positioning face and the needle groove of the rubber core has a step corresponding to the rotary positioning face; the two sides of the welding of the metal pipe and the ground wire of the cable wire has an opening groove, and the external surface of the rubber core has a groove corresponding to the welding. The utility model has the advantages of convenient assembly and maintenance, and good insulation and voltage resistance performance.
Description
The utility model relates to a kind of cable joint, particularly a kind of high-tension cable joint.
Cable joint on the market generally adopts the method for injection moulding to make now, glue core and shell are injection molded into one, during maintenance, be difficult to take apart, thereby maintenance is inconvenient, in a single day shell is just pulled down and can not be re-used, in addition, pressure is arranged during injection moulding, also the distance of the weld of the heart yearn of cable and contact pin, ground wire and metal tube can be become near, thereby influence the insulation and the withstand voltage properties of cable joint.
The purpose of this utility model provides a kind of dismounting, easy to maintenance, insulation, the high-tension cable joint that withstand voltage properties is good.
The technical scheme that realizes above-mentioned purpose is: a kind of high-tension cable joint, form by contact pin, metal tube, glue core, cable and shell, the center of glue core is a needle tray, also have a fairlead that is communicated with needle tray on the glue core, metal tube is sleeved on the glue core, and the rear portion of contact pin is installed in the needle tray of glue core, cable is installed in the other end of needle tray, the heart yearn of cable and the welding of contact pin afterbody, the ground wire of cable and metal tube welding, outer cover suit is on glue core and metal tube; The afterbody of contact pin has anti-rotation locating surface, and has the step corresponding with the positioning of rotating face in the needle tray of glue core; The both sides of the weld of the ground wire of metal tube and cable have open slot, and have on the outer surface of glue core and above-mentioned weld corresponding groove.
After adopting technique scheme, outer cover suit is on glue core and metal tube, metal tube is sleeved on the glue core, thereby can be easily with shell and glue core and metal tube separately, be convenient to install and partition, easy to maintenance, shell can be reused, and can single replacing contact pin, glue core or metal tube, saved maintenance cost.In addition, the distance of the heart yearn of cable, the weld of ground wire can be not close because of injection moulding, thereby insulation, withstand voltage properties are good.The afterbody of contact pin has anti-rotation locating surface, and has the step corresponding with the positioning of rotating face in the needle tray of glue core, adopts this structure, can prevent relatively rotating between contact pin and the glue core.Again because the both sides of the weld of the ground wire of metal tube and cable have open slot, and have on the outer surface of glue core and this weld corresponding groove, during installation, the metal of this weld can be pressed in groove, the protuberance that prevents weld makes the shell protuberance, thereby can keep the smooth and attractive in appearance of case surface.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is an internal structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of contact pin among Fig. 1;
Fig. 3 is the right view of Fig. 2;
Fig. 4 is the structural representation of glue core among Fig. 1;
Fig. 5 is the vertical view of Fig. 4;
Fig. 6 is the structural representation of metal tube among Fig. 1;
Fig. 7 is the A-A cutaway view of Fig. 6;
Fig. 8 is the upward view of Fig. 6.
As shown in Figure 1, a kind of high-tension cable joint, be made up of contact pin 1, metal tube 8, glue core 3, cable and shell 5, the center of glue core 3 is a needle tray 4, also has a fairlead 6 that is communicated with needle tray 4 on the glue core 3, metal tube 8 is sleeved on the glue core 3, the rear portion of contact pin 1 is installed in the needle tray 4 of glue core 3, and cable is installed in the other end of needle tray 4, the heart yearn 2 of cable and the welding of contact pin 1 afterbody, the ground wire 7 of cable and metallic sheath 8 welding, shell 5 is sleeved on glue core 3 and the metal tube 8; The afterbody of contact pin 1 has anti-rotation locating surface 1-1, and has the step 3-1 corresponding with positioning of rotating face 1-1 in the needle tray 4 of glue core 3; Metal tube 8 has open slot 11 with the both sides of the weld 8-1 of the ground wire 7 of cable, and has on the outer surface of glue core 3 and above-mentioned weld 8-1 corresponding groove 9.Metal tube 8 can adopt nickel plated copper pipe, because the electric conductivity of copper is relatively good.
As shown in Figure 2, have the projection 8-2 that stretches out to the tubular axis heart from tube wall on the inwall of metal tube 8, and on the outer surface of glue core 3, have and this projection 8-2 corresponding groove 10.When metal tube 8 cover installed on the glue core 3, above-mentioned projection 8-2 can snap in the groove 10 on glue core 3 outer surfaces, thereby can avoid metal tube 8 to come off from glue core 3, also can prevent relatively rotating between metal tube 8 and the glue core 3, makes installation more reliable.
Installation steps of the present utility model are as follows: 1, elder generation is welded to the heart yearn 2 of cable on the solder side of contact pin 1; 2, the rear portion with contact pin 1 places in the needle tray 4 of glue core 3, and the ground wire with cable passes fairlead 6 simultaneously; 3, metal tube 8 cover is installed on the glue core 3, and the projection 8-2 on the bobbin inwall is cooperated with groove 10 on the glue core 3; 4, the ground wire of cable is welded to the weld 8-1 of metal tube 8; 5, shell 5 covers are installed on glue core 3 and the metal tube 8.
