Abstract

The utility model discloses a contact fitting for OSM circuit breakers. The contact fitting comprises a wire clamping module and a wiring module which are manufactured integrally; the wire clamping module is composed of two wire clamping plates, one ends of the two separate wire clamping plates are integrally molded into a combined end, the other ends are separate ends hung in the air, and a first screw hole is opened at the combined end; and a second screw hole and a third screw hole are opened on the wiring module. The wire clamping plates of the contact fitting for OSM circuit breakers can provide constant contact pressure and maintain a low contact resistance and has strong transition capability, the contact fitting is simple in structure and convenient to install and repair, and the work efficiency is greatly improved.

Description

An OSM type circuit breaker contact fitting

technical field

The utility model relates to a contact fitting for an OSM circuit breaker.

Background technique

With the continuous development of my country's economy, people have higher and higher requirements for power supply reliability and power quality. According to statistics, power lines and equipment joint failures account for more than 50% of power accidents. At present, the 20kV line is put into operation, and the number of newly installed OSM circuit breakers continues to increase. However, due to the small contact area between the internal thread of the OSM circuit breaker terminal and the copper-aluminum joint, the contact is unreliable or even inaccessible. Very difficult, seriously affecting safe work production and power supply reliability.

Utility model content

In order to solve the above problems, the purpose of this utility model is to provide a contact fitting for an OSM circuit breaker, the splint of which can provide constant contact pressure, maintain low contact resistance and have strong transition ability, simple structure, convenient installation and maintenance , greatly improving work efficiency.

The utility model is for achieving above-mentioned purpose, and the utility model adopts following technical scheme:

A contact fitting for an OSM circuit breaker, including a wire clamp module and a wiring module, and the wire clamp module and the wiring module are manufactured integrally; It becomes the merged end, and the other end is suspended and separated into the separated end; the merged end is provided with a first screw hole; the wiring module is respectively provided with a second screw hole and a third screw hole.

The angle between the external extension line of the clamp module and the wiring module is 20-40o.

The included angle is 30o.

The separated ends of the two splints are connected by bolts.

The beneficial effects of the utility model are as follows: the utility model provides a contact fitting for an OSM circuit breaker, the splint of which can provide constant contact pressure, maintain low contact resistance and have strong transition ability, simple structure, and convenient installation and maintenance , greatly improving work efficiency.

Detailed ways

Example 1

As shown in Figure 1 and Figure 2, what this embodiment provides is a contact fitting for an OSM circuit breaker, including a wire clamp module 1 and a wiring module 2, and the wire clamp module 1 and the wiring module 2 are integrally manufactured; the The wire clamp module 1 is composed of two wire splints 4, one end of the two separated wire splints 4 is integrally manufactured to form a merged end, and the other end is suspended in the air and separated into a separate end; the merged end is provided with a first screw hole 3; The module 2 is respectively provided with a second screw hole 6 and a third screw hole 7 . The included angle between the external extension line of the wire clip module 10 and the wiring module 2 is set at an angle a, and the included angle a is 30°. The separated ends of the two splints 4 are connected by bolts 5 .

When using an OSM circuit breaker provided in this embodiment to contact fittings, first insert the terminal of the OSM circuit breaker into the first screw hole 3. Then use the bolt 5 to fix the clamp module 1 and the terminal of the OSM circuit breaker. Then use bolts to guide the lead wires to be fixedly overlapped with the second screw hole 6 . Finally, use bolts to guide the cable head to be fixedly overlapped with the third screw hole 7 to realize the installation process of the contact fittings of the OSM circuit breaker.

The contact fittings for an OSM circuit breaker produced in this embodiment can provide a constant contact pressure with its wire splint, maintain low contact resistance and have strong transition capability. Its structure is simple, easy to install and maintain, and greatly improves work efficiency.
