The utility model has the advantages that: the positioning piece is connected with the electric wire through riveting, the test piece is integrally formed, the structure is simple, the use is convenient, materials are saved, and the defect that the electric wire is easy to break is overcome.

Description

Small-size electric leakage circuit breaker test piece

Technical Field

The utility model relates to an electrical accessories, especially a small-size electric leakage circuit breaker test piece.

Background

The test piece group is an important component accessory of the small-sized leakage circuit breaker. At present, the wire is connected to the generally adoption welding technique of test piece subassembly, and this not only need consume soldering tin and power consumption is big, has also partly used the riveting technique to realize connecting, but often in order to guarantee that the electric wire does not appear disconnected touching or the bad contact condition with the test piece full contact, can be with partly naked the leaking of electric wire outside usually. Since the wire is easily broken by repeated bending, the service life of the test strip is short and the material is wasted.

Disclosure of Invention

Technical problem to be solved

In order to solve the problem, the utility model provides a simple structure uses two spacers to fix a position respectively and has solved the small-size earth leakage circuit breaker test piece of drawbacks such as contact failure and easy rupture.

(II) technical scheme

The utility model provides a small-size residual current circuit breaker test piece, includes spacer and shell fragment, the spacer below is equipped with the constant head tank, the spacer includes first spacer and second spacer, be equipped with the location nail on the first spacer.

Further, the test piece is a good conductive metal piece so that the lead wire is still conductive after being connected to the test piece.

Furthermore, the angle between the positioning piece and the elastic piece is 90 degrees, so that the equipment can be connected conveniently.

Furthermore, the locating plate and the elastic sheet are both of semicircular structures which are formed by directly bending metal into cavities, the middle of the locating plate is not closed and is provided with a pressing seam, so that poor contact or other error conditions caused by serious deformation can be avoided when the locating plate and the elastic sheet are pressed.

Further, the positioning nail penetrates from the outer surface to the inner surface of the first positioning sheet, and the design is to fix the position of the lead and prevent the lead from being bent frequently and damaged.

Furthermore, a folding opening is formed between the first positioning piece and the second positioning piece, and a folding opening is formed between the second positioning piece and the elastic piece, so that the metal sheet can be conveniently formed when being bent, and other parts cannot be easily deformed.

(III) advantageous effects

Compared with the prior art, the utility model, it has following beneficial effect: the utility model discloses be connected through the riveting between spacer and the wire, simple structure is reasonable, convenient to use, integrated into one piece, save material and overcome the drawback that the electric wire breaks easily.

Detailed Description

Preferred embodiments according to the present invention are described in detail below with reference to the accompanying drawings. It is noted that the description is intended for purposes of illustration only and not for limitation, and that those skilled in the art will recognize that the invention can be embodied in many forms and should not be construed as limited to the preferred embodiments set forth herein.

As shown in fig. 1 to 3, a small-sized residual current circuit breaker test piece, locating plate 8 below is equipped with constant head tank 1, locating plate 8 includes first locating plate 2 and second locating plate 5, be equipped with location nail 3 on the first locating plate 2. When the conducting wire is connected with the test piece, the conducting wire is subjected to wire stripping in advance, then the conducting part is placed in the second positioning sheet, and the rest part is placed in the first positioning sheet. Then the positioning nail 3 on the first positioning plate 2 is used for positioning and fixing, and then the positioning plate is riveted and fixed.

Preferably, the test piece is a good conductive metal piece so that the lead wire is still conductive after being connected to the test piece.

Preferably, the angle between the positioning piece 8 and the elastic piece 4 is 90 degrees, so that the connection between the devices is convenient, and the angle can be customized according to different requirements.

Preferably, the positioning piece 8 and the elastic piece 4 are both directly bent into a cavity-shaped semicircular structure by metal, the middle of the positioning piece is not closed and is provided with a pressing seam 7, so that poor contact or other error conditions caused by serious deformation can be avoided during pressing.

Preferably, the positioning pin 3 penetrates from the outer surface to the inner surface of the first positioning sheet 2.

Preferably, be equipped with between first spacer 2 and the second spacer 5 and roll over mouthful 6, and be equipped with between second spacer 5 and the shell fragment 4 and roll over mouthful 6 and more make things convenient for the shaping more and can not make other positions warp easily than the sheetmetal when buckling.

Preferably, the positioning piece 8 and the elastic piece 4 are integrally formed, so that the structure not only saves materials, but also greatly saves labor and time and improves the working efficiency.
