Utility model content
Technical problem to be solved in the utility model is the construction inconvenience that the traditional vacuum circuit breaker turnover mode of connection exists, the problem that electric conductivity is not good.
The technical scheme that realizes the utility model object is:
A kind of vacuum circuit-breaker, comprises breaker body and is arranged on the externally threaded binding post that is provided with on described breaker body; Also comprise the pole holding wire clamp being fixedly connected on described binding post, described pole holding wire clamp comprises the wire clip body being connected and composed successively by pole portion, connecting portion and flat part, be located at the wire clamp gland of described flat part, with the first bolt assembly that is connected described flat part and described wire clamp gland; Between described wire clamp gland and described flat part, be provided with the clamping hole of clamping external wire; Described pole portion is provided with the screwed hole arranging vertically, and described pole portion and described binding post are spirally connected fixing; The sidewall of described screwed hole is provided with the crack arranging vertically, and the both sides of described crack are provided with clamping plate, and described clamping plate are provided with the second bolt assembly.
In technique scheme, described wire clip body is integrated punch forming part, described connecting portion is gradually the bell mouth shape of expansion, and the serrated end of described connecting portion and described pole portion are connected smoothly, and the expansion end of described connecting portion and described flat part are connected smoothly.
In technique scheme, the quantity of described wire clamp gland is two.
In technique scheme, the clamp hole described in the involutory formation of wire casing on wire casing and described flat part on described wire clamp gland.
The utlity model has positive effect:
(1) vacuum circuit-breaker of the present utility model, in the time of wiring, is spirally connected the binding post of the pole portion of pole holding wire clamp and vacuum circuit-breaker fixing, the line end of external wire is inserted in clamping hole, and pass through fastening the first bolt assembly and clamping wire; Adopt this mode of connection only can produce two contacts (than the few contact of traditional wired mode), therefore major loop resistance is less, makes electric conductivity better; And use Wrench to operate, without using hydraulic test, construct more convenient; Can make pole holding wire clamp more reliable with being connected of binding post by fastening described the second bolt assembly, electric conductivity is better.
(2), in the utility model, adopt the described wire clip body that the mode of punching press copper coin is made to be in use difficult for rupturing, and processing technology is simple; In addition, due to the special construction of connecting portion, make connecting portion there is larger cross section, thereby can effectively improve the ampacity of product, simultaneously also can be for pole portion provides certain back stretch, help the resilience of pole portion to reset, so just can make product to reuse.
