Description
Technical field
The present invention relates to technical field of electric equipment, particularly a kind of contact switch.
Background technology
At present, family expenses or the switch of enterprise are switched using contact mostly, and it includes movable contact and stationary contact, generally made
Movable contact and stationary contact are two metal balls or metal coupling, and the contact surface between it is smaller, are contacted for, in circuit
When operating current is larger, electric arc can be produced between sound contact, contact surface is burnt, can make to hold after long-time use
Contact failure is closed, forms potential safety hazard.
The content of the invention
It is contemplated that at least solves one of above-mentioned technical problem in correlation technique to a certain extent.Therefore, this hair
It is bright to propose that a kind of contact area is big, the less contact switch of generation electric arc.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of contact switch, including stationary contact and movable contact, the stationary contact are the metal cartridge that cross section is arch,
The movable contact is the sheet metal to stationary contact curving, and the width of movable contact is more than the width of stationary contact.
As the improvement of above-mentioned technical proposal, the stationary contact with it is silver-plated at movable contact contact position.
As the further improvement of above-mentioned technical proposal, the stationary contact side is fixedly installed the first connector lug, described
Movable contact side is connected with the actuating mechanism of its action of driving, and the top or bottom of movable contact are fixedly installed the second connector lug.
Further, the stationary contact is connected with the first junction block, and first junction block is hollow, and first junction block one end is set
The through hole of first connector lug can be accommodated by having, and the first junction block bottom is provided with the first screw, and the first fixing bolt is from bottom to top
It is screwed into first screw and is abutted with the first junction block inwall.
Further, the movable contact is also associated with the second junction block, and second junction block is hollow, second junction block one end
It is provided with the second screw provided with the lug boss coordinated with second connector lug, at the top of the second junction block, the second fixing bolt is from upper
Second screw is screwed under and and is abutted with the second junction block inwall.
Further, the grip part of both sides protrusion to the left and right is provided with the middle part of the movable contact.
The beneficial effects of the invention are as follows：The present invention is matched somebody with somebody using the cylinder shape stationary contact of protrusion with the sheet movable contact bent
Close, form linear contact, contact area is big, and the electric arc that can effectively reduce between contact produces, and use is safer, and can hold
It is wider by bigger operating current, use range.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
