Need, in the loading of the bottom of pedestal, to be then fixed on pedestal by punching press, efficiency of assembling is low, and adds production cost.
The content of the invention
The shortcomings that in order to overcome background technology and weak point, the present invention provide a kind of side-mounted knot of the arc extinction part of contactor
The problem of structure, the arc extinction part installation for solving existing switch need stamping procedure, and its efficiency of assembling is low, and cost is high.
The technical scheme is that：A kind of side-mounted structure of the arc extinction part of contactor, including pedestal, arc extinction part and shield
Cover, the shield are connected with pedestal, and the pedestal is provided with some dividing plates, and mounting groove is formed between the adjacent dividing plate,
The medial surface of the dividing plate is provided with guide rail, and the inner of the dividing plate is provided with baffle plate, and the arc extinction part slips into simultaneously along guide rail straight line
Contact on baffle plate, in addition to limit arc extinction part to the card-bit part of movement on the outside of dividing plate, and the shield is contacted at outside arc extinction part
Side.
The guide rail is outwardly along dividing plate inner side, and the side of the arc extinction part is provided with and the guide rail slides what is coordinated
Chute, the card-bit part are boss and are respectively arranged on the upper and lower surface of guide rail.
The card-bit part forms with guide rail integrated injection molding.
The outer end of the boss is inclined plane, and the inner is card plane.
The inner side of the shield is provided with chuck, and the outside of the arc extinction part is provided with neck, and the chuck is contacted in neck.
The chuck forms with shield integrated injection molding.
The invention has the advantages that：Because the arc extinction part of the switch does not need punching press after the installation of the side of pedestal
Process can be fixed on arc extinction part on pedestal.It the advantage is that and remove stamping procedure from, save stamping machine program, improve dress
With efficiency, and reduce cost.

Embodiment
Embodiments of the invention are described further below for accompanying drawing：
As illustrated, a kind of side-mounted structure of the arc extinction part of contactor, including pedestal 1, arc extinction part 2 and shield 11, institute
State shield 11 with pedestal 1 to be connected, the pedestal 1 is provided with some dividing plates 3, and mounting groove is formed between the adjacent dividing plate 3
4, the medial surface of the dividing plate 3 is provided with guide rail 5, and the inner of the dividing plate 3 is provided with baffle plate 6, and the arc extinction part 2 is straight along guide rail 5
Line is slipped into and contacted on baffle plate 6, in addition to the card-bit part 8 that limitation arc extinction part 2 moves to the outside of dividing plate 3, and the shield 11
Contact at the outside of arc extinction part 2.Guide rail is set in the inner side of dividing plate, the guide rail can be groove, or projective structure, arc extinction part
It can be slid along guide rail straight line, during installation, in the side of pedestal, i.e. the opening of mounting groove inwardly loads arc extinction part, arc extinguishing
Part slips into along guide rail, until arc extinction part is in contact with baffle plate, that is, is installed in place, then arc extinction part is limited by card-bit part
Position, limit it and skidded off towards dividing plate outside, spacing in pedestal relevant position.And card-bit part has the function that to prevent from exiting.Root
According to such scheme, because the arc extinction part of the switch does not need stamping procedure arc extinction part can be fixed after the installation of the side of pedestal
In on pedestal.It the advantage is that and remove stamping procedure from, save stamping machine program, improve efficiency of assembling, and reduce cost.
In the present invention, the guide rail 5 is outwardly along the inner side of dividing plate 3, the side of the arc extinction part 2 be provided with it is described
The chute 7 that the sliding of guide rail 5 coordinates, the card-bit part 8 are boss and are respectively arranged on the upper and lower surface of guide rail 5.The guide rail is strip
The line slideway of shape tabular, the medial surface of dividing plate is fixed on, and boss is integrally fixed in the upper and lower surface of guide rail 5, it is along upper
Lower surface outwardly convex, the chute sliding of guide rail and arc extinction part side coordinate, and when arc extinction part assembles inward along guide rail, slide
When, when sliding certain position, boss is in contact with the chute of arc extinction part, passes through extruding so that arc extinction part slips over boss and supported
Touch in baffle plate, so as to have the function that anti-back to arc extinction part by boss.
In the present invention, the card-bit part 8, i.e. boss and the integrated injection molding of guide rail 5 and..It is easy to process.Outside the boss
Hold as inclined plane 9, the inner is card plane 10.The end of slipping into of boss 7 is inclined plane 9, and card plane 10 is perpendicular, middle mistake
It is horizontal plane to cross face, using said structure so that arc extinction part easily slides into along boss 7, easy to operation, and screens stability is high.
In the present invention, the inner side of the shield 11 is provided with chuck 12, and the outside of the arc extinction part 2 is provided with neck 13, institute
Chuck 12 is stated to contact in neck 13.Arc extinction part is withstood by shield, has the 2nd anti-back effect to arc extinction part, makes arc extinction part work
Safety and reliability when making.
In the present invention, the chuck 12 forms with the integrated injection molding of shield 11.Using integrated injection molding, it is easy to process.
Embodiment is not construed as the limitation to invention, but any spirit based on the present invention is made
