Description
Technical field
The present invention relates to a kind of pedestal general assemblies of electric switch.
Background technique
Currently, the pedestal general assembly of the electric switch provided in the market generally comprises pedestal and the arc-chutes in pedestal, go out
Arc chamber is made of left arc-chutes and right arc-chutes, and static contact and arc-extinguish chamber, left arc extinguishing are equipped in left arc-chutes and right arc-chutes
Be equipped with contact between room and right arc-chutes and support that static contact lower part is set in arc-extinguish chamber, the arc extinguishing magnetic blow-out of this pedestal general assembly compared with
Weak, breaking capacity is lower, and contact is supported to be easy to produce shaking when moving up and down, and then influences the use of electric switch, this
Outside, touching bridge is moved to be easily bent under electrodynamic repulsion force.
Summary of the invention
In view of the deficiency of background technique, technical problem to be solved by the invention is to provide a kind of arc extinguishing magnetic blow-out abilities more
By force, breaking capacity is higher, guidance capability is stronger and is capable of the pedestal general assembly of the anti-stop touching curved electric switch of bridge.
For this purpose, the present invention is to adopt the following technical scheme that realize:
A kind of pedestal general assembly of electric switch, the arc-chutes including pedestal and in pedestal, the arc-chutes are by left arc extinguishing
Room and right arc-chutes composition, are equipped with static contact and arc-extinguish chamber in the left arc-chutes and right arc-chutes, the left arc-chutes and
It is equipped with contact between right arc-chutes and supports and move touching bridge, the static contact lower part is set in arc-extinguish chamber, and wherein arc-extinguish chamber is equipped with
The U-shaped part of magnetic conductive metal, the static contact lower part are set between arc-extinguish chamber and the U-shaped part of magnetic conductive metal, and the pedestal is equipped with
Sealing element, the sealing element, which is equipped with, holds the through-hole that contact supports top to be pierced by, and the base bottom is equipped in the dynamic touching bridge of alignment
The groove in portion, the groove is interior to be equipped with spring, is equipped with bolster between the spring and dynamic touching bridge.
The arc-extinguish chamber front and rear sides are equipped with open slot, in the both sides insertion opening slot of the U-shaped part of magnetic conductive metal.
The bolster is U-shaped, and bolster both ends have bending part, and bending part is against on dynamic touching bridge.
The bolster bottom, which is equipped with, holds the column that spring is arranged.
After adopting the above technical scheme, arc-extinguish chamber be equipped with the U-shaped part of magnetic conductive metal, static contact lower part be set to arc-extinguish chamber and
Between the U-shaped part of magnetic conductive metal, keep the arc extinguishing magnetic blow-out ability of pedestal general assembly stronger, while breaking capacity is also higher, and seals
Shaking is generated when the setting of part effectively avoids contact from supporting to move up and down, guidance capability is stronger, keeps the movement of electric switch more steady
Fixed, in addition, the setting of bolster effectively prevent dynamic touching bridge to generate bending under electrodynamic repulsion force, and bolster both ends are with being against
Bending part on dynamic touching bridge, keeps the two contact area bigger, structure is more stable.
Detailed description of the invention
The present invention has following attached drawing:
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is sectional view along A-A in Fig. 1；
Fig. 3 is the structural schematic diagram of arc-extinguish chamber, static contact and the U-shaped part of magnetic conductive metal in the present invention.
Specific embodiment
Referring to shown in above-mentioned attached drawing, the pedestal general assembly of electric switch provided by the invention includes pedestal 1 and in pedestal 1
