Problems solved by technology

Such a switch coil 5 is designed according to a closed magnetic circuit, but after the key switch is turned on, the magnetic circuit of the movable iron core and the electromagnetic switch is in an open state, so that the magnetic field force of the metal coil does not fully play like this. The consumption of more metal wires will lead to an increase in the overall manufacturing cost of the starter

Abstract

The invention aims to provide a novel coil rack for an electromagnetic switch. The coil rack comprises a first baffle plate, a second baffle plate, a coil drum and two half-moon-shaped baffle plates. The coil winding mode in the prior art can be changed by utilizing the coil rack, and the excitation capability of coils can be improved.

Description

[0001] technical field [0002] The invention relates to the technical field of starters for automobile engines and other engines, in particular to a coil former for an electromagnetic switch and a coil winding method. [0003] Background technique [0004] The starter is composed of three parts: electromagnetic operating mechanism, DC motor and transmission mechanism. Such as figure 1 as shown in figure 1 It is an electromagnetic switch structure of a starter in the prior art. The electromagnetic switch structure of the starter is mainly composed of a switch housing 4, a switch coil 5, a static contact seat 7, a static iron core 8, a moving contact 12, a moving iron core 1, a maintenance spring 13, and a return spring 11. The switch coil 5 in the electromagnetic switch is composed of an attracting coil and a holding coil. The turns of the two coils are equal and the first ends are connected together for a terminal to lead out. The first end of the attracting coil is ...
