An iron core post clip tie

Abstract

The utility model relates to a cable tie with clamping head of an iron core column, which belongs to the technical field of transformer production, and comprises a cable tie, a cushion layer and a clamping head. The cable tie includes a ring strap, a hanging ear and an end ear. The ring strap is in the shape of an open strip, which can be enclosed in a circle. There are hanging lugs on the outer side of the endless belt close to the free end, and a plurality of hanging ears are evenly distributed on the outer side of the endless belt close to the free end. One end of the underlayment is glued to the inside of the ring strap end ear, and the other end remains free when the cable tie is tied. The chuck includes a tie rod, a cylindrical head, a bolt and a small nut. The tie rod has a pair. The pair of tie rods are inserted into the end ear and the hanging ear respectively. Both ends of the tie rod have cylindrical heads. The cylindrical head is installed eccentrically. The outside sides are flush. Bolt has a pair, and a pair of bolt is installed in the cylindrical head of upper and lower sides respectively, and small nut also has a pair, and small nut is on the bolt, locks chuck.

Description

technical field [0001] The invention belongs to the technical field of transformer production, and in particular relates to an iron core column clip tie. Background technique [0002] In the manufacturing process of the transformer core, the binding of the core column is a very important process. The binding method of the iron core column, the binding material and the quality of the binding directly affect the mechanical strength, loss and noise of the transformer core. In particular, the requirements for binding materials are relatively strict, requiring high tensile force, small elasticity, and good thermal stability. The binding tapes used for binding iron cores are generally resin-impregnated glass fiber binding tapes, and sometimes PET polyester Ties. When binding the iron core with glass fiber straps, it is generally necessary to use specially made fastening clips on the strapping straps for fastening. However, most of the clips at this time are of metal structure, an...

Problems solved by technology

When binding the iron core with fiberglass strapping, it is generally necessary to use specially made fastening clips on the strapping straps for fastening. However, most of the clips at this time are of metal structure, and the shape of the metal clips is very easy to squeeze Damage to the iron core. Moreover, the current common binding straps are not adaptable to iron cores of different diameters. The length of the binding strap is fixed, and the adjustment device is only at the bolt of the metal chuck. It is mainly used to adjust the binding strength. Very limited ability to adjust
