Existing fixed contact comprises contact frame and contact group, the contact group is installed in the described contact frame, the contact level is stacked constitutes by several for the contact group, stacked good contact group places contact frame internal fixation, in general, the following structure of the many employings of contact: the contact both sides are equipped with relative film guiding slot, and the conducting strip that is used to conduct electricity is installed in the film guiding slot of each contact.
Adopt the contact group of this kind structure, occur following point easily: at first,, will cause the fault of circuit breaker under conduction state if the conducting strip of the contact both sides that are placed in contacts; Secondly, the contact group is that the contact level is stacked constitutes by several, place contact frame internal fixation to constitute fixed contact then, like this, when the moving contact level is inserted fixed contact, be positioned at several conducting strips on the moving contact be difficult for fixed contact on several conducting strips connect one to one, thereby influence the job stability and the reliability of circuit breaker.
Summary of the invention:
Goal of the invention of the present utility model, be defective at above-mentioned prior art existence, a kind of contact that is applied to the circuit breaker fixed contact is provided, adopt the contact group of the contact formation of this structure, the conducting strip that can not only guarantee arbitrary contact both sides is insulated from each other, can guarantee simultaneously that several conducting strips on the moving contact and the corresponding conducting strip of fixed contact be accurately corresponding connection one by one, thereby has guaranteed the stability and the reliability of circuit breaker work when moving contact insertion fixed contact.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of contact that is applied to the circuit breaker fixed contact, comprise the contact panel, the both sides correspondence of described contact panel is provided with left conductive film track and right conductive film track, conducting strip is installed in described left conductive film track and the right conductive film track, be provided with insulating trip between described left conductive film track and the right conductive film track, the height of described insulating trip is greater than the height of described conducting strip.
Further, described insulating trip is located at the leading section of described left conductive film track and right conductive film track.
Further, the nock of described insulating trip is provided with the oblique angle.
Further, described contact panel is provided with location hole, and described location hole is divided on the cell wall of conductive film track of described contact panel both sides, and the described position of positioning hole that is positioned at contact panel both sides is relative.
Further, described location hole is divided into centrally-located hole and several edge location holes, and described centrally-located hole is positioned at the middle part of described contact panel; Described several edge location holes are positioned at the marginal position of described contact panel.
The beneficial effects of the utility model are:
The utility model provides a kind of contact that is applied to the circuit breaker fixed contact, adopt the contact group of the contact formation of this structure, the conducting strip that can not only guarantee arbitrary contact both sides is insulated from each other, can guarantee simultaneously when moving contact inserts fixed contact, several conducting strips on the moving contact and the corresponding conducting strip of fixed contact be accurately corresponding connection one by one, thereby has guaranteed the stability and the reliability of circuit breaker work.
