Abstract

The utility model is a pulling connection structure of hollow expanded conductor and pressure strain clamp, which comprises a clamp aluminum pipe of the pressure strain clamp, a filling bar, an inner sleeve, and a steel anchor of pressure strain clamp. One end of the steel anchor is provided with an extending strain bar, and the conductor's connection end to be pulled has a section of stranded wires to make the conductor pull through the clamp aluminum, and the filling bar is combined with the strain bar at one end of the steel anchor, and then inserted into the inner sleeve, and further into the hollow aluminum of the inner layer of conductor. The stranded wires of the connection end to be pulled wrap the strain bar so as to implement the first shrinkage processing on the inner sleeve, and then move the clamp aluminum pipe to the suitable position of the inner sleeve. And then, the secondary shrinkage processing comes to finish the pulling connection of hollow expanded conductor and pressure strain clamp.

Summary of the invention

The purpose of this utility model is to provide the drawing syndeton of a kind of hollow expanded conductor and crimping and tension-resisting clip, making hollow expanded conductor and crimping and tension-resisting clip carry out drawing is connected when making up, its drawing assemble very simple and easy fast, and drawing connects very firm of effect.

The purpose of this utility model is to realize like this, the drawing syndeton of a kind of hollow expanded conductor and crimping and tension-resisting clip, it comprises that wire clamp aluminum pipe, a filler rod, an inner sleeve of a crimping and tension-resisting clip, the steel anchor and of a crimping and tension-resisting clip have the hollow expanded conductor for the treatment of the drawing link;

Described hollow expanded conductor will treat that in advance the aluminium hollow parts and the aluminium stranded conductor of drawing link all separated, and only keep more than one section steel strand wire;

The wire clamp aluminum pipe of described crimping and tension-resisting clip is an adaptive body that is placed on the hollow expanded conductor;

Filler rod is a real barred body of filling, the aluminium hollow parts of the adaptive insertion hollow of its diameter expanded conductor internal layer, and an end has a thread segment;

The steel anchor of crimping and tension-resisting clip is a solid rod iron, and steel anchor one end and have the solid shape strain insulator rod that one is extended, and offers one in this strain insulator rod one end and can establish the screw of combination for the thread segment lock of filler rod;

Inner sleeve is one can be placed on the body of strain insulator rod, and forms one treat the czermak space that the steel strand wire of drawing link are implanted for the hollow expanded conductor between inner sleeve and strain insulator rod;

By above-mentioned member, the hollow expanded conductor runs through by the wire clamp aluminum pipe, the filler rod lock is established the strain insulator rod that is incorporated into steel anchor one end, be inserted in inner sleeve again, filler rod inserts the aluminium hollow parts of lead internal layer, this lead treats that the steel strand wire of drawing link are implanted described czermak space and bag is put the strain insulator rod, the wire clamp aluminum pipe is moved to the appropriate location of inner sleeve.

The wire clamp aluminum pipe of this crimping and tension-resisting clip is to adopt aluminium to make a body.

One end of the wire clamp aluminum pipe of this crimping and tension-resisting clip has a drainage plate.

This filler rod is to adopt steel to make.

This inner sleeve is to adopt steel to make a body.

The strain insulator rod outer surface of this crimping and tension-resisting clip one end is integrally formed with most bulge loops.

In sum, the drawing syndeton of hollow expanded conductor of the present utility model and crimping and tension-resisting clip, it is specially adapted to the hollow expanded conductor and is connected combination with the drawing of crimping and tension-resisting clip, integral body connects to form not only fast convenient, and it is very firm, there is not the anxiety that comes off, the stability and security that helps electric power to carry.

Embodiment

Extremely shown in Figure 7 as Fig. 2, the drawing syndeton of hollow expanded conductor of the present utility model and crimping and tension-resisting clip, it steel anchor 4 that comprises wire clamp aluminum pipe 1, a filler rod 2, an inner sleeve 3 and a crimping and tension-resisting clip of a crimping and tension-resisting clip is formed, be connected combination for hollow expanded conductor 100 with the drawing of crimping and tension-resisting clip, wherein:

The wire clamp aluminum pipe 1 of crimping and tension-resisting clip can be adopted aluminium matter and make a body, be nested with a hollow expanded conductor 100 for adaptive, and wire clamp aluminum pipe 1 one ends has a drainage plate 11, for the junction surface that is incorporated into a drainage tube (not shown);

Filler rod 2 is to adopt steel to make a real barred body of filling with designated length, the aluminium hollow parts 10 of the adaptive insertion hollow of its diameter expanded conductor 100 internal layers, and an end has a thread segment 21;

Inner sleeve 3 is to adopt steel to make a body, for being placed on following strain insulator rod 41, and forms a czermak space a at this inner sleeve 3 and strain insulator rod 41, implants with the steel strand wire 20 that provide hollow expanded conductor 100 to treat the drawing link;
