Contact connection auxiliary structure for microswitch

Abstract

The invention discloses a contact connection auxiliary structure for a microswitch, which comprises a shell, one end of the top of the shell is rotatably connected with a touch seesaw, one end of the touch seesaw far away from a rotating shaft is fixedly connected with an iron block, one end of the top of the shell close to the iron block is fixedly connected with an electromagnet, and the electromagnet is magnetically connected with the iron block. When the touch switch is pressed downwards, an extrusion rod at the bottom of a connecting rod makes contact with the switch, an electromagnet attracts an iron block downwards, the iron block is attracted through the electromagnet, force needed for pressing the touch seesaw is reduced, and therefore the touch seesaw can be pressed conveniently. Unstable circuit connection caused by insufficient extrusion force is avoided; the U-shaped connecting sheets are arranged at the two wiring boards in the microswitch, and the upper end and the lower end of the conductive contact are arc-shaped, so that the contact area of the conductive sheets during circuit connection is increased, and short circuit caused by unsmooth current flow is avoided.

Description

Technical field: [0001] The invention belongs to the technical field of switch auxiliary accessories, in particular to a contact connection auxiliary structure for a micro switch. Background technique: [0002] The micro switch is a contact mechanism with a small contact interval and a snap-action mechanism, and the switch action is performed with a specified stroke and a specified force. There is a driving rod outside the switch. Because the contact distance of the switch is relatively small, it is called a micro switch. It is also called a sensitive switch, a quick switch actuated by pressure, and is widely used in door switches in anti-theft systems. [0003] In the prior art, the contacts of traditional micro switches are mostly connected by means of inserts. When the switch is turned on, the two guides have a certain angle, which leads to poor current flow and easy short circuit. , and the touch rocker outside the micro switch needs to be pressed with a constant force ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, most of the contacts of traditional micro switches are connected by means of inserts. When the switch is turned on, the two guides have a certain angle, which leads to poor flow of current and easily leads to short circuit. , and the touch rocker outside the micro switch needs to be pressed with a constant force after being pressed. If it is pressed manually, the force is not accurately grasped, which will easily lead to the disconnection of the switch circuit and cause the circuit connection to be unstable.
