Embodiment 1

[0024] Such as figure 1 and figure 2 As shown, in the present invention, the wire lead-out part 3 is composed of a holder 11 and an accommodating pool 10 of adhesive 12. The holder 11 is cup-shaped and has a bottom 9 through which the wire 2 passes. In the present invention, the holding tank 10 is filled with the adhesive 12, and after the adhesive 12 is hardened, the wire lead-out portion 3 is fixed on the outer peripheral surface of the molded electromagnetic coil 1.

[0025] According to the electromagnetic coil of the present invention, the following beneficial effects can be obtained.

[0026] (1) The hydraulic pressure 13 acting on the wire lead-out part 3 from the outside and the resin pressure 14 acting on the lead-lead lead-out part 3 from the inside of the electromagnetic coil are absorbed by the adhesive force of the adhesive 12 .

[0027] (2) Such process automation can be realized, the wire 2 passes through the bottom 9 of the holder 11, the holding pool 10 is...

Abstract

A retarder electromagnetic coil has lead wire pull-out portions, each comprising: a holder having a bottom portion wherethrough a lead wire of an electromagnetic coil passes and an adhesive pit filled with an adhesive.

Description

technical field [0001] The present invention relates to a solenoid for a speed reducer which is mounted on a vehicle as a brake assist device, and more particularly, the present invention relates to a solenoid for a speed reducer which has an improved Lead lead-out part. Background technique [0002] In the conventional electromagnetic coil of the speed reducer, each end of the wire is respectively connected to the front end and the tail end of the electromagnetic coil, and the wire is led out from the electromagnetic coil to the outside, and is fixed outside the molded electromagnetic coil. Accordingly, water easily enters the coil from the outside of the molded coil along the wire, and therefore, there is a risk that the waterproofness of the coil is lowered.
