Abstract
A connector of high voltage power cable comprises a fixer with a C-shaped cross section and a wedge-shaped member which is arranged in the fixer, wherein an electric wire clamp groove is left between two ends of the wedge-shaped member and the fixer, and the wedge-shaped member is formed by the connection of two elements which are concave-convex embedded with each other and are rotated in a certain angle, then a screw bolt is fixed on a hole site which is opened on the wedge-shaped member and the fixer separately. The wedge-shaped member formed by the connection of two elements which are movingly concave-convex embedded with each other is arranged in the C-shaped fixer, further the high voltage power cable is excessively clamped by the wedge-shaped member leading to the imbalance of tensile force of the power cable, and thereby the problem is solved by the utility model effectively. The contacting area of the wedge-shaped member to the power cable is the same as the contacting area of the electric ware clamp groove of two ends of the power cable to the power cable, and a screw bolt connecting mode is adopted by the connection of the wedge-shaped member and the fixer, thereby the moving angle of the two elements of the wedge-shaped member is controlled effectively, and a special tool which is used to fix the connection of the wedge-shaped member and the fixer is saved, then the cost is reduced effectively, further the assembling and disassembling are convenient.
Description
Technical field
The utility model relates to high-tension cable parts manufacturing technology field, is the used power cable connector of a kind of high-tension electricity transmission specifically.
Background technology
At present, in high-tension electricity transmission industry, because the voltage that high voltage power cable transmitted is extra-high pressure, thereby the design of power cable connector is even more important.Existing high voltage power cable connector all is the holders that adopt C type or other V-arrangements, device has the wedge shape part of tape cable clip slot in holder, but this wedge shape part generally is whole integral structure, and need specific purpose tool that wedge shape part and holder are fixed up, trouble is installed, also need uses the specific purpose tool dismounting during dismounting.Because the wedge shape part is integrated, when the tension force of thermal expansion can appear during because of tension clamping cable in a certain end of the cable clip slot of wedge shape part two ends, cause two cable tension imbalance phenomenons easily, when serious even cause burning cable conductor.
The utility model content
The purpose of this utility model is the shortcoming that overcomes above-mentioned prior art, provides a kind of simple in structure, and easy installation and removal can effectively keep the high voltage power cable connector of cable equalization of strain.
The utility model can be achieved through the following technical solutions:
A kind of high voltage power cable connector, comprise that the cross section is the holder of C type and places the interior wedge shape part of holder, on two end positions of wedge shape part and leave the electric wire clip slot between the holder, described wedge shape part is formed by connecting by two parts uneven and that can rotate at an angle, one is bolted on the position, hole that wedge shape part and holder offer separately, the Kong Weijun that wedge shape part and holder are offered separately is the oval shape, can certainly be the position, hole of strip, two parts that help the wedge shape part are like this opened appropriate exercise under the long effect at cable.
Described wedge shape part is formed by parts with recess and parts phase embedding with protuberance, and two parts can rotate at an angle around concavo-convex connecting portion, and this angle is between 0 to 20 degree.
The holder that electric wire clip slot that leaves on two end positions of wedge shape part and cross section are the C type forms the cable folder hole.
Cable is contained in the electric wire clip slot that leaves on wedge shape part two end positions, then the wedge shape part is inserted in the holder of C shape, the bolt of packing on the position, hole by holder and wedge shape part is also fixing, if during a certain electric wire clip slot tension clamping cable of wedge shape part two ends, the tension force that this moment, high-tension cable was produced when transferring high voltage electric power can be to the electric wire clip slot applied thrust of the wedge shape part other end, two parts of stressed wedge shape part can be to doing suitable rotation (scope that certain wedge shape part two parts rotate is accepted the tightness of bolt and controlled), the two ends stress balance of so effective maintenance wedge shape part two parts, the tension imbalance phenomenon that tension force occurred that can occur thermal expansion when avoiding electric wire clip slot tension clamping cable guarantees that wedge shape part two ends and cable contact area balance each other.
The utility model compared with prior art has following advantage:
Two uneven parts of the utility model employing activity are formed the wedge shape part and are placed in the C clamp seat, efficiently solve high-tension cable by the tension imbalance phenomenon that wedge shape part tension clamping cable occurs, guaranteed that the wedge shape part is identical with the cable contact area with cable two end electric wire clip slots; And the connected mode of this wedge shape part and holder adopts bolt connecting mode, effectively controls the angle of two parts activities of wedge shape part, reduces and uses specific purpose tool to fix being connected between wedge shape part and the holder, effectively reduces cost and easy installation and removal.

Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the holder structural representation;
Accompanying drawing 3 is wedge shape part two a parts assembling schematic cross-section;
Accompanying drawing 5 is subjected to the tension structure schematic diagram for the utility model wedge shape part two parts.
Embodiment
Come the utility model is further described below in conjunction with Figure of description:
As accompanying drawing 1, accompanying drawing 2, shown in the accompanying drawing 3, a kind of high voltage power cable connector, comprise that the cross section is the holder 1 of C type and places wedge shape part 2 in the holder 1, on two end positions of wedge shape part 2 and leave electric wire clip slot 3 between the holder, described wedge shape part is formed by connecting by two parts uneven and that can rotate at an angle, there is a bolt 4 to be fixed on the position, hole 31 that wedge shape part 2 and holder are offered separately, on 32, the Kong Weijun that wedge shape part and holder are offered separately is the oval shape, can certainly be the position, hole of strip, two parts that help the wedge shape part are like this opened appropriate exercise under the long effect at cable.
Described wedge shape part is formed by parts with recess and parts 21,22 phase embeddings with protuberance, two parts can around concavo-convex connecting portion at an angle a rotate, this angle a is between 0 to 20 degree.
The holder that electric wire clip slot 3 and the cross section of leaving on two end positions of wedge shape part 2 is the C type forms the cable folder hole.
Cable is contained in the electric wire clip slot 3 that leaves on wedge shape part 2 two end positions, then the wedge shape part is inserted in the holder 1 of C shape, the bolt 4 and fixing of packing on the position, hole by holder and wedge shape part, as shown in Figure 4; If during a certain electric wire clip slot of wedge shape part two ends 3 tension clamping cables 7, the tension force that this moment, high-tension cable was produced when transferring high voltage electric power can be to the electric wire clip slot applied thrust of the wedge shape part other end, two parts of stressed wedge shape part can be to doing suitable rotation and moving to the loose other end, as shown in Figure 5, certain wedge shape part two parts 21,22 scopes of rotating are accepted the tightness of bolt 4 and are controlled, the two ends stress balance of so effective maintenance wedge shape part two parts, the tension imbalance phenomenon that tension force occurred that can occur thermal expansion when avoiding electric wire clip slot tension clamping cable guarantees that wedge shape part two ends and cable contact area balance each other.
