Abstract
The utility model relates to a core-bunched strain clamp comprising an upper wedge core, a middle wedge core and a lower wedge core in wedge-shaped fit, and pulling plates respectively arranged on the outer surfaces of the upper wedge core and lower wedge core, wherein the upper wedge core, the middle wedge core, the lower wedge core and the pulling plates are fixed by fixing bolts; and compression springs are further arranged between the upper wedge core and middle wedge core and between the middle wedge core and lower wedge core. The utility model has the beneficial effects that the nuts on the fixing bolts can be unscrewed during the installation and use, so that the upper wedge core, the middle wedge core and the lower wedge core can be automatically popped to the required position of the insulated conductor, thus achieving the effects of convenient installation and high reliability.
Description
Technical field
The utility model relates to a kind of boundling strain clamp that is used for overhead transmission line.
Background technology
In power circuit, the clustering insulation strain clamp is applicable to bundle assembled aerial cable terminal or strain section two ends, play the effect of fixed strain clustering insulation cable, product adopts core number minute four-core, two cores of pressing cable, need not divest insulating barrier during installation, boundling strain clamp in using at present generally comprises arm-tie, goes up wedge core, middle wedge core, hyposphene core, and by bolt, because the strain clamp of this kind setting needs manually to draw back the installation site that the hyposphene core is adjusted required insulated conductor in installing and using, installation inconvenience and reliability are low.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, provides a kind of easy installation and reliable property high boundling strain clamp.
For achieving the above object, the utility model adopts a kind of clustering insulation strain clamp, comprise the last wedge core that is wedge-like engagement, middle wedge core, hyposphene core and be separately positioned on the wedge core and the arm-tie of hyposphene core lateral surface, wherein saidly go up wedge core, middle wedge core and hyposphene core and arm-tie is fixed by set bolt, between the last wedge core and middle wedge core of described boundling strain clamp, be provided with the compression spring between middle wedge core and the hyposphene core.
As preferably, the installation site of described compression spring is on set bolt and axially concentric with this set bolt.
In installing and using process, owing to be provided with the compression spring, when unclamping bolt and nut, just elastic force will be gone up the wedge core to this compression spring and the hyposphene core flicks certain position from employing, the distance that flicks is regulated by described bolt, at last wedge core and hyposphene core bullet to suitable distance, cable is fixedly mounted, avoided original usefulness manually to draw back the action of wedge core and hyposphene core, and the strain clamp of this wedge-like engagement is by after being provided with the compression spring, and its grip force also promotes greatly, compared to original boundling strain clamp, easy for installation, the reliability height.

Embodiment
Shown in Fig. 1-9, specific embodiment of the utility model is a kind of four-core centralized strain clamp, as shown in Figure 1, the strain clamp of the utility model embodiment comprises two arm-ties (4,4 '), two identical last wedge core 1 and hyposphene cores 1 ', middle wedge core 3, six compression springs 2 and three bolt components 5, wherein each bolt component comprises a set bolt 51, nut 52, a spring washer 53 and a plain washer 54; As shown in Figure 6, the both sides, upper end of last wedge core 1 and hyposphene core 1 ' respectively have a semicircle cell body, the both sides of the upper and lower side of middle as shown in Figure 8 wedge core 3 respectively have one with the described corresponding semicircle cell body of going up on wedge core 1 and the hyposphene core 1 ' of semicircle cell body, and at upper and lower wedge core (1,1 ') with after middle wedge core 3 wedge-like engagement constitute four trunking bodies jointly, described two arm-ties (4,4 ') be separately positioned on the lateral surface of wedge core 1 and hyposphene core 1 ', and the upper, middle and lower wedge core of described arm-tie and wedge-like engagement is fixing by bolt component 5; As shown in Figure 1, wherein the set bolt 51 of each bolt component 5 pass respectively be arranged between wedge core 1 and the middle wedge core 3, two compression springs 2 between middle wedge core 3 and the hyposphene core 1 ', in the use, the nut 52 that only need unclamp on the bolt component 5 just can automatically spring open wedge core 1 and hyposphene core 1 ' by the elastic force of compression spring 2, adjusts the position that cable is installed.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to execution mode of the present utility model.For those of ordinary skill in the field; can also make other changes in different forms on the basis of the above description, and these belong to conspicuous variation or the change that spirit of the present utility model amplified out and still are among the protection range of the present utility model.
Claims (2)
1. boundling strain clamp, comprise the last wedge core that is wedge-like engagement, middle wedge core, hyposphene core and be separately positioned on the wedge core and the arm-tie of hyposphene core lateral surface, wherein saidly go up wedge core, middle wedge core and hyposphene core and arm-tie is fixed by set bolt, it is characterized in that: between the last wedge core and middle wedge core of described boundling strain clamp, be provided with the compression spring between middle wedge core and the hyposphene core.
