Description
Technical field
Technical field of electric equipment is the utility model is related to, particularly a kind of contact switch.
Background technology
At present, family expenses or the switch of enterprise are switched using contact mostly, it includes movable contact and stationary contact, usually makes
Movable contact and stationary contact are two metal balls or metal coupling, and the contact surface between it is smaller, is point contact, 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 security risk.
Utility model content
The utility model is intended to solve one of above-mentioned technical problem in correlation technique at least to a certain extent.For this reason,
The utility model proposes a kind of contact area it is big, produce the less contact switch of electric arc.
Technical solution is used by the utility model solves its technical problem：
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；The stationary contact
Side is fixedly installed the first connector lug, and the movable contact side is connected with the actuating mechanism of its action of driving, the top of movable contact
Portion or bottom are fixedly installed the second connector lug；The stationary contact is connected with the first junction block, and first junction block is hollow, the
One junction block one end is equipped with the through hole that can accommodate first connector lug；The movable contact is also associated with the second junction block, described
Second junction block is hollow, and second junction block one end is equipped with the lug boss coordinated with second connector lug.
As the improvement of above-mentioned technical proposal, the stationary contact with it is silver-plated at movable contact contact position.
Further, the first junction block bottom is equipped with the first screw hole, and the first fixing bolt is screwed into described from bottom to top
One screw hole is simultaneously abutted with the first junction block inner wall.
Further, it is equipped with the second screw hole at the top of second junction block, the second fixing bolt is screwed into described the from top to bottom
Two screw holes are simultaneously abutted with the second junction block inner wall.
Further, the grip part of both sides protrusion to the left and right is equipped with the middle part of the movable contact.
The beneficial effects of the utility model are：The utility model is moved using the cylinder shape stationary contact of protrusion with curved sheet
Contact coordinates, and forms linear contact, and contact area is big, and the electric arc that can effectively reduce between contact produces, and use is safer, and
The operating current of bigger can be born, use scope is wider.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
