The contact pushing device of the control and protection switch electric appliance has better action consistency and more stable structure.
Description
Technical Field
The utility model relates to a low-voltage apparatus field, concretely relates to contact thrust unit of control and protection switch electrical apparatus.
Background
At present, a contact pushing device of a control and protection switching device provided in the market is generally fixed on a support by adopting a jackscrew through a thread fastening and manual adjusting mode, and then a main contact is pushed by the support to act. The jackscrew is easy to have the unstable faults of structures such as slide fastener, cracks and the like in the assembly, and meanwhile, the action consistency is difficult to ensure by means of manual adjustment.
Disclosure of Invention
In view of the deficiency of the background art, the technical problem to be solved in the utility model is to provide a control and protection switch electrical apparatus's contact thrust unit that action uniformity is better and the structure is more stable.
Therefore, the utility model discloses an adopt following technical scheme to realize:
the contact pushing device of the control and protection switching device comprises a plurality of contact supports and a support, wherein the contact supports are movably arranged on a base of the control and protection switching device in a penetrating mode, the support is hinged in a shell of the control and protection switching device, one side of the support is aligned with the upper end of the contact support, the lower portion of the contact support is provided with a contact bridge and static contact pieces on two sides of the contact support, both sides of the contact bridge are provided with movable contacts, and the static contact pieces are provided with static contact points aligned with the movable contacts, and the contact pushing device is characterized in that: the support aligned with the upper end of the contact support is provided with a plurality of through holes, and the through holes are riveted with rivets which can abut against the upper end of the contact support and can drive the contact support to move downwards.
Further, the rivet is made of metal.
After the technical scheme is adopted, the phenomena of cracks and sliding buckles in the prior art are effectively avoided through riveting of the rivets and the support, the consistency of the support for pushing the contact is improved, the actions of the contact bridge and the movable contact are more accurate, the phenomenon of contact burning is avoided, and meanwhile, the support structure is more stable.
Drawings
The utility model discloses there is following figure:
fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic view of the three-dimensional structure of the middle bracket and the rivet of the present invention.
Reference numerals: 1. a contact support; 2. a support; 3. contacting the bridge; 4. a static contact piece; 5. a movable contact; 6. a stationary contact; 7. a through hole; 8. and (4) riveting.
Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the objects of the present invention, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.
Referring to the attached drawings, the contact pushing device of the control and protection switching device comprises a plurality of contact supports 1 and a support 2, wherein the contact supports 1 are movably arranged on a base of the control and protection switching device in a penetrating manner, the support 2 is hinged in a shell of the control and protection switching device, one side of the support 2 is aligned to the upper end of the contact supports 1, the lower part of the contact supports 1 is provided with a contact bridge 3 and static contacts 4 on two sides of the contact supports 1, two sides of the contact bridge 3 are respectively provided with a movable contact 5, and the static contacts 4 are provided with a static contact 6 aligned to the movable contact 5, and the contact pushing device is characterized in that: the support 2 aligned with the upper end of the contact support 1 is provided with a plurality of through holes 7, the through holes 7 are riveted with rivets 8 which can be abutted against the upper end of the contact support 1 and can drive the contact support 1 to move downwards, and the rivets 8 are made of metal materials.
In this embodiment, through a plurality of rivets 8 and support 2 riveting, effectively avoid the phenomenon of crackle, thread slipping among the prior art, improved support 2 and promoted the uniformity that contact supported 1, and then make the action of contact bridge 3 and movable contact 5 more accurate, avoid taking place the phenomenon that the contact cauterized, support 2 structure is more stable simultaneously.
The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention has been disclosed by the preferred embodiment, it is not limited to the present invention, and any person skilled in the art can make modifications or changes equivalent to the equivalent embodiments by utilizing the above disclosed technical contents without departing from the technical scope of the present invention, but all the modifications, changes and changes of the technical spirit of the present invention made to the above embodiments are also within the scope of the technical solution of the present invention.
