Abstract
The utility model relates to a high voltage cable connector, which is composed of a bus bar and a casing tube, wherein, one end of the metallic connecting body of the bus bar is provided with input ports, and the other end is provided with a welding groove; an outer stud is inserted in the welding groove to be welded and fixed; the periphery of the metallic connecting body of the bus bar is provided with a rubber insulating layer; one end of the metallic body of the casing tube is provided with internal threads, and the other end is provided with an output interface of the casing tube; the periphery of the matallic body of the casing tube is provided with a rubber insulating layer; the bus bar and the casing tube are screwed into a whole. The utility model has the characteristics that the creepage distance is extended; the water resisting property is good; when big current passes, the utility model can not heat; meanwhile, the utility model has other characteristics. The utility model has the advantages of novel design and reasonable conception. Meanwhile, the utility model can meets the requirements of domestic users and the product is practical enough to be popularized for use.
Description
The utility model belongs to the high-tension cable connector.
At present external and domestic American series or European series all do not have the sleeve pipe busbar, and domestic ring main unit, switch cubicle, distribution box wish that all this series products is arranged.
The purpose of this utility model provides a kind of good waterproof performance, prolong creepage distance and big electric current by the time high-tension cable sleeve pipe busbar that can not generate heat.
The purpose of this utility model can realize by following measure:
The utility model is made up of busbar A, sleeve pipe B, and busbar A is connected with sleeve pipe B's, screws with sleeve pipe B internal thread by the external double-screw bolt of busbar to engage, and this connects, and to insert by the hexagon wrench that inner hexagonal hole screws be an integral body; Above-mentioned described busbar A is the busbar input port that three symmetries are set in an end center of busbar metal connected body, the other end is provided with welding groove, it is fixing that one end of the external double-screw bolt of busbar embeds the welding groove welding, in the external double-screw bolt of busbar periphery the output interface ring seat is set, busbar metal connected body periphery is provided with insulating barrier, in the peripheral part of insulating barrier conductive layer is set; Above-mentioned described sleeve pipe B is provided with internal thread in sleeve pipe metallic object one end center, and the other end is provided with the sleeve pipe output interface, and interface the inner is provided with hexagon ring.In sleeve pipe metallic object periphery insulating barrier is set.
The utility model adopts interference fit, good waterproof performance; Size lengthening in electro-insulating rubber loop has prolonged creepage distance, and the external double-screw bolt of busbar embeds welding groove and fixes, make big electric current by the time do not generate heat yet.
The accompanying drawing drawing is described as follows:
Fig. 1 is the utility model structure chart;
Fig. 2 is the utility model busbar left view;
Fig. 3 is the utility model sleeve pipe right view.
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):
With reference to accompanying drawing 1-3, the utility model is made up of busbar A, sleeve pipe B, and busbar A is connected with sleeve pipe B's, screws with sleeve pipe B internal thread 12 by the external double-screw bolt 2 of busbar A to engage, and this connects, and to insert by the hexagon wrench that inner hexagonal hole 10 screws be an integral body; Above-mentioned described busbar A is by busbar metal connected body 1, the external double-screw bolt 2 of busbar, output interface ring seat 3, welding groove 4, busbar input interface 5, conductive layer 6, insulating barrier 7 is formed, the busbar input port 5 of three symmetries is set in an end center of busbar metal connected body 1, the other end is provided with welding groove 4, it is fixing that one end of the external double-screw bolt 2 of busbar embeds welding groove 4 welding, reduce contact resistance, make big electric current by the time do not generate heat yet, in the external double-screw bolt of busbar 2 peripheries output interface ring seat 3 is set, busbar metal connected body 1 periphery is provided with rubber insulation 3, at the peripheral local semi-conductive rubber that adopts of rubber insulation conductive layer 5 is set; Above-mentioned described sleeve pipe B is made up of sleeve pipe metallic object 8, sleeve pipe output interface 9, inner hexagonal hole 10, sealing lengthening insulator 11, internal thread 12, insulating barrier 13, in sleeve pipe metallic object 8 one end centers internal thread 12 is set, the other end is provided with sleeve pipe output interface 9, interface 9 the inners are provided with hexagon ring 10, in sleeve pipe metallic object 8 peripheries rubber insulation 13 are set; Sealing lengthening electro-insulating rubber ring on busbar output interface ring seat 4 and the sleeve pipe adopts interference fit, and sealing is strong, has solved the problem of waterproof, and prolongs creepage distance.When sleeve pipe busbar input interface access bus, electric current passes through metal connector, the external double-screw bolt of busbar, sleeve pipe metallic object, sleeve pipe output interface on ring main unit or terminal equipment.Insulating barrier parcel busbar and sleeve surface, to guarantee leakproof under the high pressure conditions, conductive layer discharges the electro-insulating rubber laminar surface because of the electrostatic charge ground connection that high pressure generates, avoid electric charge to gather.
The external double-screw bolt of abnormity busbar can connect normal sleeve as required.Special-shaped casing tube and umbrella shape sleeve pipe etc.
