[0033] Reference below Figure 1-Figure 5 A starter 100 according to an embodiment of the present invention is described.

[0034] Reference Figures 1 to 4 According to an embodiment of the present invention, a starter 100 includes a starter housing 10 , an electromagnetic switch 20 and a waterproof rubber sleeve 30 .

[0035] The starter housing 10 is provided with a stopper 11 and a first connection part 12. The electromagnetic switch 20 is provided with a second connection part 21. The waterproof rubber sleeve 30 is provided between the starter housing 10 and the electromagnetic switch 20, the second connection part 21 is connected to the first connection part 12, and the stopper 11 stops the side of the waterproof rubber sleeve 30 away from the electromagnetic switch 20, so that the waterproof rubber sleeve 30 is attached to the electromagnetic switch 20 toward the side of the electromagnetic switch 20. Among them, the waterproof rubber sleeve 30 is provided with a positioning hole 31, and the positioning hole 31 is sleeved on the first connection part 12 or the second connection part 21 to position the waterproof rubber sleeve 30.

[0036] Among them, the first connecting part 12 is connected to the second connecting part 21, so as to fix the electromagnetic switch 20 on the starter housing 10. A waterproof rubber sleeve 30 is installed between the starter housing 10 and the electromagnetic switch 20. The waterproof rubber sleeve 30 is used to prevent external water from penetrating into the electromagnetic switch 20, thereby avoiding rust and failure of the electromagnetic switch 20.

[0037] In the related art, the electromagnetic switch of the starter is usually provided with a rubber ring to prevent water from penetrating. However, the rubber ring may be deformed or displaced during the installation process, resulting in water penetration.

[0038] In the embodiment of the utility model, a positioning hole 31 is provided on the waterproof rubber sleeve 30, and the first connecting portion 12 or the second connecting portion 21 between the starter housing 10 and the electromagnetic switch 20 is passed through the positioning hole 31 to position the waterproof rubber sleeve 30, so that the waterproof rubber sleeve 30 is always in a fixed position, thereby avoiding deformation and displacement of the waterproof rubber sleeve 30 during the assembly process, avoiding sealing failure, and improving sealing stability.

[0039] There may be a plurality of positioning holes 31 , and the plurality of positioning holes 31 are arranged along the circumferential direction of the waterproof rubber sleeve 30 to fix multiple parts of the waterproof rubber sleeve 30 , thereby further improving the sealing stability.

[0040] Specifically, the first connection portion 12 or the second connection portion 21 is configured as a columnar structure, and the columnar structure is passed through the positioning hole 31 to position the waterproof rubber sleeve 30 .

[0041] It can be understood that the first connecting portion 12 is connected to the second connecting portion 21 to fix the electromagnetic switch 20 on the starter housing 10. The force between the starter housing 10 and the electromagnetic switch 20 acts on the waterproof rubber sleeve 30 to exert axial compression and improve the sealing performance.

[0042] According to the starter 100 of the embodiment of the utility model, by setting a positioning hole 31 on the waterproof rubber sleeve 30, the waterproof rubber sleeve 30 is positioned by using the first connecting part 12 or the second connecting part 21 to avoid deformation and displacement of the waterproof rubber sleeve 30, so that the waterproof rubber sleeve 30 always works normally, avoids sealing failure, and improves sealing stability.
