Abstract
The utility model discloses a tension string shield ring which is an annular body provided with at least one opening. A plurality of support leg connecting parts respectively detachably connected with a support leg each are convexly arranged on the inner edge of the shield ring. Since the opening is arranged on the annular body of the tension string shield ring, the tension string shield ring can be annularly arranged around a divided conductor or the tension string so as to reach good shielding effect. A plurality of the support legs of the shield ring can be detachably fixed on the inner edge of the annular body, so the support legs can not hinder the installation of the shield ring when installing the shield ring. Compared with the existing shield rings, the tension string shield ring has the advantage that the support legs are shorter, thus being capable of supporting stably.

The utility model content
The purpose of this utility model is to provide a kind of strain insulator-string shading ring, and this shading ring can be located on around lead or the strain insulator-string, to reach good shield effectiveness.
Another purpose of the present utility model is to provide a kind of strain insulator-string shading ring, and the supporting leg on this shading ring is short and can dismantle, and makes shading ring easy for installation and can improve stability.
The purpose of this utility model is to realize like this, a kind of strain insulator-string shading ring, described shading ring convexes with a plurality of supporting leg connecting portions for being provided with the ring bodies of an opening at least on the inner edge of this shading ring, described each supporting leg connecting portion is connected with a supporting leg respectively removedly.
In a better embodiment of the present utility model, described supporting leg connecting portion is connected with cover type nut by snap bolt with corresponding supporting leg link.
In a better embodiment of the present utility model, the other end of described each supporting leg is fixedly connected on respectively on conductor spacer or the strain insulator-string gold utensil.
In a better embodiment of the present utility model, described shading ring is annular, oval ring or the straight-flanked ring that has big fillet.
In a better embodiment of the present utility model, described shading ring is provided with two openings, and this shading ring is made of two relative semicircular bodies.
In a better embodiment of the present utility model, described shading ring is made by the aluminum pipe bending.
In a better embodiment of the present utility model, the end that is positioned at the ring bodies of described opening both sides is provided with the cup head body isometrical with described aluminum pipe.
From the above mentioned, because its ring bodies of strain insulator-string shading ring of the present utility model is provided with an opening, it can encircle establishes (that is: sheathed) around bundle conductor or strain insulator-string, to reach good shield effectiveness; Because a plurality of supporting legs of shading ring removably are fixed on the inner edge of this ring bodies, therefore, described supporting leg can not hinder the in place of shading ring when this shading ring was installed; Further, owing in the utility model a plurality of described shading rings can be installed near strain insulator-string, therefore, reaching under the situation of same shield effectiveness, the physical dimension that can avoid shading ring is excessive and cause the long defective of its supporting leg, existing relatively shading ring, it is shorter that shading ring of the present utility model props up leg length, can realize stable support preferably.

Embodiment
Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast description of drawings embodiment of the present utility model.
Shown in Figure 1A and Figure 1B, a kind of strain insulator-string shading ring, described shading ring 1 convexes with a plurality of supporting leg connecting portions 12 for being provided with the ring bodies of an opening 11 on the inner edge of this shading ring 1, and described each supporting leg connecting portion 12 is connected with a supporting leg 2 respectively removedly.
From the above mentioned, because its ring bodies of strain insulator-string shading ring of the present utility model is provided with an opening, it can encircle establishes (that is: sheathed) around bundle conductor or strain insulator-string (shown in Fig. 4 A and Fig. 4 B), to reach good shield effectiveness; Because a plurality of supporting legs of shading ring removably are fixed on the inner edge of this ring bodies, therefore, described supporting leg can not hinder the in place of shading ring when this shading ring was installed; Further, owing to a plurality of described shading rings can be installed (shown in Fig. 4 A and Fig. 4 B in the utility model near strain insulator-string, three shading rings all are installed), therefore, reaching under the situation of same shield effectiveness, the utility model can avoid the physical dimension of existing structure shading ring excessive and cause the long defective of its supporting leg, existing relatively shading ring, it is shorter that shading ring of the present utility model props up leg length, can realize stable support preferably.
