Abstract

The utility model discloses a strain clamp, including fastener main part and drainage plate, be equipped with mutual lapped connection face between fastener main part and the drainage plate and through bolted connection, be equipped with the location arch and the positioning groove that mutually support on the connection face between fastener main part and drainage plate respectively, the location is protruding stupefied including round confined rectangle, and is protruding stupefied along the bar that transversely and vertically is equipped with a plurality of mutually perpendicular in protruding stupefied enclose regional of rectangle, the bolt is located in the protruding stupefied region of enclosing of rectangle. The beneficial effects are that: owing to be equipped with location arch and the positioning groove who mutually supports on the connection face between fastener main part and drainage plate respectively, not only make the connection more firm, avoided mutual emergence rotatory, increased the contact surface area between fastener main part and the drainage plate in addition, make resistance reduce, can avoid corona and electric discharge phenomena to take place, save the electric energy.

Description

A kind of strain clamp

Technical field

This utility model is related to a kind of electric armour clamp, more particularly to a kind of strain clamp.

Background technology

Strain clamp is used for for wire or lightning conducter being fixed on non-rectilinear shaft tower strain insulator string, plays anchoring and conductive work With also for fixing the bracing wire of bracing wire shaft tower.

Existing strain clamp is mainly formed by wire clip body and drainage plate assembly connection, and wire clip body and drainage plate are flat Face contact connection, and fastened by securing member.During product use in the presence of high-tension current, strain clamp can produce heat Swollen shrinkage, causes wire clip body gap occur with the contact surface of drainage plate, and contact surface corrosion and the mutually phenomenon such as rotation occurs, Cause resistance to increase, corona and electric discharge phenomena occur, so as to waste electric energy.

The content of the invention

Technical problem to be solved in the utility model is to provide a kind of simple structure, is connected firmly, and can avoid corona And electric discharge phenomena occur, the strain clamp of electric energy is saved.

To solve the above problems, this utility model is adopted the following technical scheme that：

A kind of strain clamp, including wire clip body and drainage plate, are provided with mutual overlap joint between wire clip body and drainage plate Joint face is simultaneously bolted, and it is characterized in that：Phase is respectively equipped with joint face between wire clip body and drainage plate The positioning convex for mutually coordinating and detent, the positioning convex includes that the rectangle of a circle closing is convex stupefied, stupefied surrounds rectangle is convex Region in be transversely provided with that multiple orthogonal bar shapeds are convex stupefied with longitudinal direction, the bolt is located at that the rectangle is convex stupefied to be surrounded In region.

Used as further preferred, the positioning convex is arranged on the joint face of wire clip body, and the detent is located at On the joint face of drainage plate.

Used as further preferred, the rectangle is convex stupefied and the convex stupefied cross section of bar shaped is triangle.

Used as further preferred, the convex stupefied longitudinally arranged quantity of the bar shaped is two.

Used as further preferred, the bolt is two and is distributed in the convex stupefied region for surrounding of the rectangle.

As further preferred, wire clamp steel anchor is plugged with the jack of wire clip body upper end, for by the strain clamp It is fixed on shaft tower.

The beneficial effects of the utility model are：Due to being respectively equipped with phase on the joint face between wire clip body and drainage plate The positioning convex for mutually coordinating and detent, not only make connection more firm, it is to avoid mutually rotates, and increases line Contact surface area between clip main body and drainage plate, reduces resistance, and corona and electric discharge phenomena can be avoided to occur, and saves electricity Energy.

Specific embodiment

As depicted in figs. 1 and 2, a kind of strain clamp that this utility model is related to, including wire clip body 1 and the drain of aluminum Plate 2, is provided with the joint face of mutual overlap joint and is connected by bolt 4 between wire clip body 1 and drainage plate 2, the wire clip body 1 is L-type and the longer horizontal segment of its length are hollow-core construction, grafting and clamping have wire clamp steel anchor in the jack of the upper end of wire clip body 1 3, the outer end of wire clamp steel anchor 3 is the single-unit iron chains shape of closing, for the strain clamp to be fixed on into shaft tower.

As shown in Figure 3 and Figure 4, determining of cooperating is respectively equipped with the joint face between wire clip body 1 and drainage plate 2 Position raised 5 and detent 6, the positioning convex 5 includes the rectangle convex stupefied 501 of a circle closing, surrounds in rectangle convex stupefied 501 Transversely with longitudinal direction multiple orthogonal bar shapeds convex stupefied 502 are provided with region, the convex stupefied 502 longitudinally arranged number of the bar shaped Amount is preferably two.The bolt 4 is two and is distributed in convex stupefied 501 region for surrounding of the rectangle, in the He of wire clip body 1 Corresponding through hole 7 is respectively equipped with correspondence bolt 4 on joint face between drainage plate 2, bolt 4 is through wire clip body 1 and drain It is locked by nut after plate 2.

Preferably, the positioning convex 5 is arranged on the joint face of wire clip body 1, the detent 6 is located at drain On the joint face of plate 2.The rectangle convex stupefied 501 and convex stupefied 502 cross section of bar shaped are triangle.

Although embodiment of the present utility model is disclosed as above, it is not restricted in description and embodiment Listed utilization, it can be applied to completely various suitable fields of the present utility model, for those skilled in the art, Other modification is easily achieved, therefore under the general concept limited without departing substantially from claim and equivalency range, this reality Specific details is not limited to new and shown here as the legend with description.
