In the process of using at strain clamp, need carry out the centre gripping to the high-voltage line, and then can reach the fixed action to the high-voltage line, but because the direction adopts all be steel-cored aluminum strand wires, consequently when strain clamp clamping, all be outside aluminum strand wires are at the atress, because the material problem of aluminum strand wires, lead to the aluminum strand wires of fixed position to warp easily after the time is long, influence life, when serious, can produce the harm that steel-cored aluminum strand wires drop.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems in the background art, the present invention provides a crimping type strain clamp, which solves the above problems.

The technical scheme is that the compression joint type strain clamp is used for fixing a steel-cored aluminum strand; the drainage wire clamp comprises a main body, a steel anchor and a drainage wire clamp; the main body includes: the steel anchor is inserted into the threading pipe; the steel anchor comprises: the pull rod comprises a crimping pipe and a pull rod with a pull ring, wherein the crimping pipe is connected with one end far away from the pull rod with the pull ring, and the diameter of the crimping pipe is smaller than that of the pull rod with the pull ring.

Further, the main body and the steel anchor are of an integrated structure.

Furthermore, a plurality of crimping grooves are formed in the end part of the pull rod with the pull ring.

Further, the drainage clamp includes: the wire clamp comprises a wire clamp connecting plate and a wire pressing pipe, wherein the wire clamp connecting plate is arranged at the end part of the wire pressing pipe.

Furthermore, an included angle of 140 degrees and 180 degrees is formed between the wire clamp connecting plate and the wire pressing pipe.

Compared with the prior art, the utility model discloses a crimping type strain clamp, which has the following specific beneficial effects:

(1) the steel anchor is directly pressed with the steel-cored aluminum strand together, so that the steel core bears most stress when the steel-cored aluminum strand is erected, the stress of the aluminum strand outside the steel-cored aluminum strand is reduced, the service life of the aluminum strand is prolonged, and the damage is reduced;

(2) the threading pipe and the outside crimping of steel-cored aluminum strand through the main part, one make prevent that aluminum strand from droing or taking place the phenomenon of returning and contracting, guarantee the effectual use of steel-cored aluminum strand, can reduce the atress of steel core simultaneously, further improve its life.
