Abstract
The utility model discloses a contact having a protective structure and used for a high-voltage breaker, which comprises a group of bar-shaped current-conducting plates arranged in a parallel way. The outer sides of the bar-shaped current-conducting plates are provided with grooved type structures. The contact further comprises a protective cover. The two ends of the protective cover are provided with clamping feet cooperating with the grooved type structures. By means of the cooperation between each clamping foot and the corresponding grooved type structure, the protective cover can straddle the upper ends of the bar-shaped current-conducting plates in a laterally sliding way. The front ends of the bar-shaped current-conducting plates are provided with fixing clamping heads. The front end part of the protective cover is provided with clamping openings corresponding to the fixing clamping heads. The contact with a simple reasonable structure is convenient to install and use. By arranging the slidable protective cover on the upper end, the contact can be protected. External foreign matters such as dust and particles can be effectively prevented from affecting the conductive performance of the contact. The stability of the contact is improved. The service lifetime of the contact is prolonged. The using safety of the high-voltage breaker is further guaranteed.
Description
Technical field
The utility model relates to a kind of circuit breaker accessory, is specially the contact of a kind of primary cut-out with safeguard structure.
Background technology
Primary cut-out is the switching device that a kind of power equipment uses, and existing primary cut-out is affected by extraneous dust and other impurities in use easily, cause the contact position electric conductivity of primary cut-out stable not, easily produce creepage phenomenon, and after long-time use, easily cause contact position to wear and tear, become flexible phenomenon,, there is potential safety hazard in the use safety that affects primary cut-out.
Utility model content
The purpose of this utility model is to provide the contact of a kind of primary cut-out with safeguard structure, to solve traditional primary cut-out in prior art, affected by extraneous dust and other impurities, cause the contact position electric conductivity of primary cut-out stable not, easily produce creepage phenomenon, and after long-time use, easily cause contact position to wear and tear, become flexible phenomenon, affect the use safety of primary cut-out, have the problem of potential safety hazard.
For achieving the above object, the technical solution adopted in the utility model is:
The contact of a kind of primary cut-out with safeguard structure, it is characterized in that: include one group of bar shaped conductive plate be arrangeding in parallel, described bar shaped conductive plate outside is provided with trench structure, also include protective cover, described protective cover two ends are provided with the card base matching with trench structure, and by card base, coordinate with trench structure can horizontally slip straddle bar shaped conductive plate upper end, described bar shaped conductive plate front end is provided with fixed chuck, described protective cover front end end is provided with the bayonet socket corresponding with fixed chuck.
The described contact of a kind of primary cut-out with safeguard structure, is characterized in that: described protective cover adopts high-temperature insulation material to make.
The beneficial effects of the utility model are:
The utility model is simple and reasonable; easy to install; employing arranges the slidably design of protective cover in contact upper end; can play a protective role to contact; effectively prevent that the foreign material such as extraneous dust, particle from affecting the electric conductivity of contact; the stability that has improved contact, has extended useful life, has guaranteed the use safety of primary cut-out.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
