Electromagnetic switch

Abstract

The invention relates to the technical field of switches, in particular to an electromagnetic switch. The electromagnetic switch comprises a frame body, an electromagnetic coil, an electric conductingstructure and a first limiting structure, wherein the electromagnetic coil is mounted on the frame body; the electric conducting structure is connected to the coil first end of the electromagnetic coil, the electric conducting structure comprises an electric conducting body and a running end arranged at one end of the electric conducting body, the running end can be in contact with the coil second end of the electromagnetic coil so as to make the electromagnetic coil to be powered on, and the running end can be separated from the coil second end to enable the electromagnetic coil to be powered off; and the first limiting structure is fixedly arranged on the frame body, and can limit the separation amplitude of the running end relative to the coil second end. The electromagnetic switch canenable the electromagnetic coil to be powered on and off more reliably by arranging the limiting structure.

Description

Technical field [0001] The invention relates to the technical field of switches, in particular to an electromagnetic switch. Background technique [0002] The electromagnetic switch, as the name implies, is a switch controlled by an electromagnet, which is a combination of an electromagnet and a switch. When the electromagnet coil is energized, electromagnetic attraction is generated, and the movable iron core pushes or pulls the switch contacts to close, thereby connecting the control circuit. Electromagnetic switches are widely used in various industries. [0003] The electromagnetic switch is powered by the electromagnetic coil to provide the pull-in power. Generally, a conductive clip is connected in series in the electromagnetic coil loop. The conductive clip can control the on-off state of the contact in the conductive clip through the operating mechanism by mechanical cooperation, and the contact is fixed. On the conductive clip, the contact plate in contact with the conta...

[0003] The electromagnetic switch is powered by the electromagnetic coil to provide the pull-in power. Generally, a conductive clip is connected in series in the electromagnetic coil circuit. The conductive clip can control the on-off state of the contact in the conductive clip through the mechanical cooperation method of the operating mechanism, and the contact is fixed. On the conductive clip, the contact plate in contact with the contact is electrically connected to the electromagnetic coil. The contact controls the energization and power loss of the electromagnetic coil by contacting and separating from the contact plate. The conductive clip is generally fixed on the bracket. In the prior art The electromagnetic switch of the electromagnetic switch usually fixes the end of the conductive sheet away from the contact on the bracket, and the end with the contact is the movable end and is in contact with or separated from the contact plate under the action of the operating mechanism. When inaccurate, the conductive clip may not be able to make quick and good contact with the contact plate, making the electromagnetic coil unreliable on and off
