Abstract

The utility model discloses an anti-exposure wire SR structure, which comprises an outer die and an inner die, wherein the outer die is sleeved with an inner die, one end of the inner die is provided with a first wire buckle, one end of the inner die, which is far away from the first wire buckle, is provided with a second wire buckle, the first wire buckle and the second wire buckle are abutted with the outer die, and the first wire buckle and the second wire buckle are abutted with the outer die to realize the supporting effect of the first wire buckle and the second wire buckle on the two ends of the outer die, so that the reduction of the yield caused by exposure of the die can be reduced, and the cost is reduced.

Description

Anti-exposure SR structure for wire

Technical Field

The utility model relates to the technical field of wire pairing structures, in particular to an anti-dew wire SR structure.

Background

SR is STRAIN RELIEF's abbreviation for eliminate the stress of wire rod, prevent the heart yearn fracture of wire rod junction, adopt rubber or other materials, intensity is different, in order to be used for different wire rods, market shaping centre form + external mold length at present exceeds more than 20mm and prevents that it all needs to add the thimble to handle to reveal the centre form badly, if SR surface has LOGO not to allow to carry the needle to handle, because do the external mold behind the shaping centre form and do not have the needle to support, it is bad just to have very high exposure centre form just to flow into at the glue, need to arrange personnel's rework.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides an anti-dew wire SR structure which can effectively solve the problems in the background art.

The technical scheme adopted by the utility model for solving the technical problems is as follows:

the utility model provides a prevent wire rod SR structure of dew, includes external mold and centre form, the external mold cup joints with the inner membrance, inner membrance one end is equipped with first line and buckles, the inner membrance is equipped with the second line in the one end of keeping away from first line and buckles and the external mold butt is buckled with the second line to first line.

Preferably, the first thread extends outwardly through the outer die.

Preferably, the second thread button extends outwards through the outer die.

Preferably, the number of the second fasteners is two.

Compared with the prior art, the utility model has the beneficial effects that:

the first wire buckle and the second wire buckle are arranged to abut against the outer die, so that the first wire buckle and the second wire buckle can support the two ends of the outer die, the yield reduction caused by die exposure can be reduced, and the cost is reduced.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 and 2, an anti-exposure SR structure for wire rods comprises an outer die 1 and an inner die 2, the outer die 1 is sleeved with the inner die 2, one end of the inner die 2 is provided with a first wire buckle 21, one end of the inner die 2 far away from the first wire buckle 21 is provided with a second wire buckle 22, the first wire buckle 21 and the second wire buckle 22 are abutted to the outer die 1, the first wire buckle 21 penetrates through the outer die 1 to extend outwards, the second wire buckle 22 penetrates through the outer die 1 to extend outwards, the number of the second wire buckles 22 is two, the supporting effect of the first wire buckle 21 and the second wire buckle 22 on two ends of the outer die 1 can be achieved by arranging the first wire buckle 21 and the second wire buckle 22 to be abutted to the outer die 1, therefore, the yield reduction and the cost reduction caused by the exposure of the die can be reduced, the outer die 1 can adopt softer rubber materials, the inner die 2 can use harder rubber materials, and the first wire buckle 21 and the second wire buckle 22 support the outer die 1 without making additional supporting and the inner die 2 And the connection reduces the production cost and improves the yield.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
