Abstract
The utility model discloses a control and protection switch electrical apparatus's contact support includes support and pillar, the support upper end is equipped with the stand, the pillar bottom surface is equipped with holds stand male guide way. The utility model provides a control and protection switch electrical apparatus's contact support adopts split type structure, is difficult for taking place to turn over the book and warp, touch bridge and movable contact action more accurate and the structure is more stable.
Description
Technical Field
The utility model relates to a low-voltage apparatus field, concretely relates to control and protection switch electrical apparatus's contact support.
Background
At present, most of contact supports of control and protection switch electric appliances provided in the market are of an integrated structure, the contact supports are made of plastics, and the contact supports are easy to melt by heating in actual use to generate rolling deformation, so that the action accuracy of a contact bridge and a movable contact is influenced.
Disclosure of Invention
In view of the not enough of background art, the utility model aims to solve the technical problem that a control and protection switch electrical apparatus's contact support that adopts split type structure, be difficult for taking place to turn over the roll deformation, touch bridge and movable contact action more accurate and structure is more stable is provided.
Therefore, the utility model discloses an adopt following technical scheme to realize:
the contact support of the control and protection switch electric appliance is characterized in that: the support is characterized by comprising a support and a support column, wherein an upright column is arranged at the upper end of the support, and a guide groove for accommodating the upright column to insert is formed in the bottom surface of the support column.
Further, the pillar is made of plastic, and the bracket is made of metal.
Furthermore, wear to be equipped with on the support and touch the bridge, touch the bridge both sides and be equipped with the movable contact, support both sides inner wall all is equipped with a plurality of can with touch the locating piece of bridge butt.
After adopting above-mentioned technical scheme, the contact supports the split type structure that adopts support and pillar, and both connect through stand and guide way, the structure is more stable, because the pillar receives the influence of electric arc less, consequently the pillar is made by plastics, it rises originally to have reduced production, and the support receives the influence of electric arc great, and the support is connected with touching the bridge, consequently the support is made by the metal, make the contact support difficult emergence roll-over deformation, and then make and touch bridge and movable contact action more accurate, in addition, support both sides inner wall all be equipped with a plurality of can with touch the locating piece of bridge butt, make support and touch the connection structure of bridge more stable.
Drawings
The utility model discloses there is following figure:
fig. 1 is a schematic perspective view of the present invention.
Reference numerals: 1. a support; 2. a pillar; 3. a column; 4. a guide groove; 5. contacting the bridge; 6. a movable contact; 7. and (5) positioning the blocks.
Detailed Description
Referring to fig. 1, the utility model provides a control and protection switch electrical apparatus's contact support includes support 1 and pillar 2, support 1 upper end is equipped with stand 3, 2 bottom surfaces of pillar are equipped with and hold stand 3 male guide way 4, pillar 2 is made by plastics, support 1 is made by the metal, wear to be equipped with on support 1 and touch bridge 5, touch bridge 5 both sides and be equipped with movable contact 6, support 1 both sides inner wall all is equipped with a plurality ofly can with touch the locating piece 7 of 5 butts of bridge.
After adopting above-mentioned technical scheme, the contact supports the split type structure that adopts support 1 and pillar 2, and both connect through stand 3 and guide way 4, the structure is more stable, because pillar 2 receives the influence of electric arc less, consequently, pillar 2 is made by plastics, it rises originally to have reduced production, and support 1 receives the influence of electric arc great, and support 1 is connected with touch bridge 5, consequently, support 1 is made by the metal, make the contact support be difficult for taking place the roll-over deformation, and then make touch bridge 5 and movable contact 6 action more accurate, in addition, support 1 both sides inner wall all is equipped with a plurality of can with touch bridge 5 butt locating piece 7, make support 1 and touch bridge 5's connection structure more stable.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
Claims (3)
