Embodiment 1

[0018] like Figure 1-2 As shown, the starter electromagnetic switch with a waterproof structure includes a switch case 2, the end of the switch case 2 is provided with a gong bolt 1 and a switch cover 2, an electromagnetic coil 5 is arranged in the switch case 2, and a switch case 2 is provided with a There is a hollow spool cavity, and a guide sleeve 7 is arranged in the spool cavity. The spool assembly 8 and the guide sleeve 7 are connected by sliding fit. 3 connections, there is still a static iron core 4 in the switch housing 2.

[0019] There are two separated grooves 9 in the valve core assembly 8, the distance between the grooves is 1-5mm, the grooves are coated with waterproof grease, and a labyrinth sealing structure is formed between the grooves 9 and the guide sleeve 7 .

Embodiment 2

[0021] In this embodiment, the valve core assembly 8 is a moving iron core assembly, and the rest of the working principle is the same as that of Embodiment 1.

Abstract

The invention discloses a starter electromagnetic switch with a waterproof structure. The starter electromagnetic switch comprises a switch shell, wherein an electromagnetic coil is arranged in the switch shell; a hollow spool chamber is arranged in the switch shell; a spool component is in sliding fit in the spool chamber; one end of the spool component is connected with a reset piece; the other end of the reset piece is connected with a contact plate. The starter electromagnetic switch is characterized in that the spool component is at least provided with a groove, so that the spool component and the spool chamber form a labyrinth seal. By a labyrinth seal structure, the electromagnetic switch is sealed; the grooves are filled in a mode of adding waterproof grease in two grooves; compared with the traditional electromagnetic switch, the starter electromagnetic switch has the advantage that the waterproofness is improved by more than 50 percent; the starter electromagnetic switch has outstanding substantial effects and remarkable progress.

Description

technical field [0001] The invention relates to a starter electromagnetic switch, in particular to a starter electromagnetic switch with a waterproof structure. Background technique [0002] Integral electromagnetic switches are widely used in automobile starters. Integral electromagnetic switches are composed of switch covers, switch housings, copper bolts, copper contact plates, static iron cores, moving iron core components, electromagnetic wire packages, and guide bushing components. Composition, working principle of the electromagnetic switch: After electrification, the electromagnetic wire package generates electromagnetic force, which drives the moving iron core assembly to move axially along the guide sleeve, when the main contact of the electromagnetic switch contacts and electrifies, at the same time the single The gear is pushed out to drive the flywheel of the engine to rotate. After the power is cut off, the moving iron core assembly is pushed by the return spr...
