Abstract
The invention discloses an OSM-type circuit breaker contact fitting. The fitting comprises a wire clamping module and a wiring module, wherein the wire clamping module and the wiring module are manufactured integrally; the wire clamping module is composed of two wire clamping plates; one ends of the two separated wire clamping plates are integrally manufactured to become a merged end, and the other ends of the two separated wire clamping plates are separated from each other in a is suspension manner to become separated ends; a first screw hole is formed in the merged end; and a second screw hole and a third screw hole are respectively formed in the wiring module. According to the OSM-type circuit breaker contact fitting provided by the invention, each wire clamping plate can provide constant contact pressure, and has high transition ability while low contact resistance is kept. The OSM-type circuit breaker contact fitting is simple in structure and convenient to install and maintain and can improve the work efficiency greatly.
Description
?
Technical field
The present invention relates to a kind of OSM type circuit breaker contact gold utensil.
Background technology
Along with the development of China's economy, people are more and more higher to power supply reliability and quality of power supply requirement, and according to statistics, power circuit, device junction fault account for the ratio of electric power accident more than 50%.Putting into operation of present stage 20kV circuit, being on the increase of the OSM type circuit breaker of new clothes, but because OSM type breaker terminal internal thread is directly very little with the contact area that copper-aluminium joint contacts, so that contact unreliable, even can not contact, install very difficultly, have a strong impact on trouble free service production and power supply reliability.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of OSM type circuit breaker contact gold utensil, its wireplint can provide constant contact, when keeping low contact resistance and the transition ability strong, it is simple in structure, and installation and maintenance are convenient, greatly improved operating efficiency.
The present invention is the purpose that reaches above-mentioned, and the present invention adopts following technical scheme:
A kind of OSM type circuit breaker contact gold utensil comprises wire clamp module, Wiring module, and wire clamp module and Wiring module is integrally manufactured forms; Described wire clamp module is comprised of two wireplints, and two defiber clamping plate one ends are integrally manufactured and become and merge end, the unsettled separating end that is separated into of its other end; Described merging end offers the first screw; Offer respectively the second screw, the 3rd screw on the described Wiring module.
Outer extended line and the angle between the Wiring module of described wire clamp module are 20-40o.
Described angle is 30o.
The separating end of described two wireplints links to each other by bolt.
Beneficial effect of the present invention is: the invention provides a kind of OSM type circuit breaker contact gold utensil, its wireplint can provide constant contact, when keeping low contact resistance and the transition ability strong, it is simple in structure, installation and maintenance are convenient, greatly improved operating efficiency.

Embodiment
Embodiment 1
As shown in Figure 1 and Figure 2, present embodiment provides a kind of OSM type circuit breaker contact gold utensil, comprises wire clamp module 1, Wiring module 2, and wire clamp module 1 and Wiring module 2 integrally manufactured forming; Described wire clamp module 1 is comprised of two wireplints 4, and two defiber clamping plate 4 one ends are integrally manufactured and become and merge end, the unsettled separating end that is separated into of its other end; Described merging end offers the first screw 3; Offer respectively the second screw 6, the 3rd screw 7 on the described Wiring module 2.The outer extended line of described wire clamp module 10 and the angle between the Wiring module 2 are a angle and arrange, and angle a is 30o.The separating end of described two wireplints 4 links to each other by bolt 5.
When a kind of OSM type circuit breaker contact gold utensil that uses present embodiment to provide, at first OSM type breaker terminal is inserted the first screw 3.Then with bolt 5 wire clamp module 1 and OSM type breaker terminal are fixed.Then fixed with the second screw 6 with the bolt guide lead-in wire.Use at last bolt guide cable end and the 3rd screw 7 fixed, realize the installation process of OSM type circuit breaker contact gold utensil.
A kind of OSM type circuit breaker contact gold utensil of present embodiment manufacturing, its wireplint can provide constant contact, when keeping low contact resistance and the transition ability strong, it is simple in structure, installation and maintenance are convenient, greatly improved operating efficiency.
