Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0013] An electromagnetic switching device, mainly composed of a main coil 6, an auxiliary coil 7, an auxiliary contact mechanism 9, a magnetic pole 3, an iron core 11, a core rod 4, a housing 1, an end cover 8, etc., the housing 1 and the end cover 8 A closed body is formed, a coil frame 2 is arranged in the shell 1, the main coil 6 and the secondary coil 7 are arranged on the coil frame 3, the secondary coil 7 is set on the outer layer of the main coil 6, and the center of the bottom of the shell 1 is provided with a magnetic pole 3. There is a spring 5 at the bottom of the conical surface of the magnetic pole 3. The core rod 4 is connected to the iron core 11 through the nut 12. The core rod 4 passes through the bottom of the shell 1 and is connected to the parts to be switched. The conical surface of the iron core 11 The shape is the same as that of the t...

Abstract

The invention discloses an electromagnetic switching device which mainly comprises a main coil, a secondary coil, an auxiliary contact mechanism, a magnetic pole, an iron core, a core bar and the like, wherein the main coil and the secondary coil are arranged on a coil rack; the secondary coil is arranged on an outer layer of the main coil; a flange is arranged at the other end of the iron core; the auxiliary contact mechanism is arranged on an end cover; and the main coil is connected with the auxiliary contact mechanism in series. When the electromagnetic switching device disclosed by the invention is electrified to work, the main coil and the secondary coil are simultaneously electrified to work and act on the iron core, and thus the actions of the iron core and the core bar are realized; after the electromagnetic switching device is started and stably works, a picking sheet on the auxiliary contact mechanism is bunted by the flange on the iron core, the main coil is cut off and the secondary coil is enabled to independently work to act on the iron core, thereby reducing current of the electromagnetic switching device in the operation process and reducing the heating phenomenon of the whole electromagnetic switching device.

Description

technical field [0001] The invention belongs to the technical field of electromechanical control, and in particular relates to an electromagnetic switching device. Background technique [0002] At present, there are many electromagnetic switching devices that have been disclosed, especially electromagnetic valves, which use the force generated when the electromagnet is energized and engaged to control the movement of the core rod or valve core to achieve the purpose of action switching. In the current electromagnetic switching device, the primary and secondary coils are mostly connected in series. When the electromagnetic switching device is working, the coil is prone to heat, which affects the stable operation and life of the electromagnetic switching device. Contents of the invention [0003] In order to solve the problems existing in the prior art, the present invention designs an electromagnetic switching device, which can realize the mutual switching of two working st...
