Problems solved by technology

Since the iron core reciprocates in the guide tube when the electromagnetic switch is working, the contact area between the two is large, not only the large sliding friction coefficient causes wear, but also the heat dissipation effect is poor, which affects the performance of the switch

Embodiment Construction

[0011] Such as figure 1 It is a structural schematic diagram of the present invention, a safety electromagnetic switch, including a casing 1, a coil 2, a guide tube 3, a static contact 4, an iron core 5 and a return spring 6, the casing 1 is cylindrical, and a through hole is opened at one end. The other end is provided with two static contacts 4, the coil 2 is installed in the shell 1, the guide tube 3 is installed in the coil 2, the return spring 6 and the iron core 5 are installed in the guide tube 3, and the iron core 5 is provided with a slide Groove 7, guide pipe 3 is provided with pulley 8. There are two chutes 7, which are evenly distributed on the longitudinal cylindrical surface of the iron core 5. Pulley 8 has two pairs, and its afterbody is connected on the guide pipe 3 inwalls, and the wheel body is embedded in the chute 7.

[0012] When working, the coil 2 is energized to generate a magnetic field to attract the iron core 5 to move. When the iron core 5 moves u...

Abstract

The invention relates to the technical field of automatic control equipment, in particular to an efficient electromagnetic switch which comprises a cylindrical shell, a coil, a guide tube, two fixed contacts, an iron core and a return spring. One end of the cylindrical shell is provided with a through hole, the other end of the cylindrical shell is provided with the two fixed contacts, the coil is mounted in the shell, the guide tube is mounted in the coil, the return spring and the iron core are mounted in the guide tube, a sliding groove is arranged on the iron core, and rollers are arranged on the guide tube and used with the sliding groove. Friction coefficient is reduced, heating is decreased, materials are saved, the heat dissipation area is increased, and performances are greatly improved.

Description

technical field [0001] The invention relates to the technical field of automatic control equipment, in particular to a high-efficiency electromagnetic switch. Background technique [0002] Existing vehicle starter electromagnetic switch is mainly made of shell, coil, guide pipe, static contact and iron core. Its function is to use the magnetic force generated by the electrification of the coil and the elastic force of the return spring to make the iron core reciprocate in the guide tube to complete the start and stop of the starter under the control of the car key door. Since the iron core reciprocates in the guide tube when the electromagnetic switch is working, the contact area between the two is large, not only the large sliding friction coefficient causes wear, but also the poor heat dissipation effect affects the performance of the switch. Contents of the invention [0003] In order to overcome the disadvantages of high friction coefficient, large wear and high heat ...
