水構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a waterproof structure for starter motor lead wires, and particularly to a waterproof structure for lead wires used in a completely waterproof starter motor.

ブの他端に連結していた。[Prior Art] Conventionally, the structure of a lead wire connecting a starter motor and a magnetic switch that supplies power to the starter motor is such that both ends of the copper stranded wire are welded to connection terminals provided on both sides, and one end of the lead wire is connected to the motor housing. It was covered with a liquid-tightly connected rubber sleeve to provide insulation and waterproofing, and the connecting portion on the magnetic switch side was covered with a detachable rubber cap, which was connected to the other end of the rubber sleeve.

があった。[Problems to be Solved by the Invention] However, when the above structure is used in a completely waterproof sealed starter motor, internal pressure increases due to heat generation, and this is transmitted to the rubber sleeve, causing pressure to increase in this area as well. The rubber cap may come off at the connecting portion, causing water to enter due to negative pressure generated as the motor cools.

落して同様の事態を生じることがある。Therefore, a structure has been proposed in which the rubber sleeve and the rubber cap are integrated to eliminate these connections (Nippon Denso Technical Report 52-274), but in this case as well, the increase in pressure inside the rubber sleeve causes attachment and detachment. The rubber cap itself may fall off and cause a similar situation.

Both ends of the conductive wire 11 are welded and connected to the connection terminals 31 of the starter motor 2 and the magnetic switch 3, respectively, and one of both ends of a rubber sleeve 12 covering the conductive wire 11 is molded integrally with the connecting portion of the conductive wire 11. The outer periphery of the connecting portion is airtightly covered.

る。1 Effect] In the waterproof structure having such a configuration, either of the both ends of the rubber rib 12 is airtightly attached to the outer periphery of the connecting portion between the conductive wire 11 and the connecting terminal 31, so that the starter motor 2
The pressure increase inside the rubber cap 13 passes through the rubber sleeve 12.

2, and its motor side end is hermetically fixed to the motor frame by a known structure.

により行う。A rubber cap 13 covers the end of the rubber sleeve 12 on the side of the magnet switch 3, and the detailed internal structure thereof is shown in FIG. The conducting wire 11 inserted into the rubber sleeve 12 is a copper stranded wire, and its both ends (only the end on the magnet switch 3 side is shown) are welded to a plate-shaped connecting terminal 31. Then, the rubber sleeve 12 is airtightly attached to the magnetic switch side end 121 so as to cover the outer periphery of the conductor connection part, and this attachment is performed by applying the rubber material of the rubber sleeve 12 to the outer periphery of the connection part in a mold. This is done by integral vulcanization molding.

The outer periphery of the part is covered with a rubber cap 13.

効に防止される。In the above-mentioned waterproof structure, when the pressure inside the starter motor increases due to heat generated during operation, this pressure propagates into the rubber sleeve, but because the end of the rubber sleeve is covered airtight, the pressure propagation is prevented. It stops here and does not reach the rubber cap. Therefore, the rubber cap is effectively prevented from falling off.

定しである。[Second Embodiment] FIG. 3 shows a second embodiment of the present invention, in which a rubber sleeve 1
One end of the conducting wire 11 inserted through the magnet switch 2 is welded to a connecting terminal 31 on the magnetic switch side, and the other end is welded to a connecting terminal 21 that is electrically connected to an unillustrated field coil of the starter motor 2. The motor-side end 122 of the rubber sleeve 12 is integrally molded to cover the outer periphery of the conductor connection part in an airtight manner, and the rubber sleeve end 122 is airtightly fixed to the motor frame 22. It is.
なお、ゴムスリーブ１２のスイッチ側端部１２１は開放
されており、ここに上記第１実施例と同様のゴムキャッ

入することはない。According to this structure, the pressure increase inside the starter motor due to heat generation does not propagate into the rubber sleeve 1-2.
Therefore, the rubber cap connected thereto will not fall off. Further, even if the rubber cap falls off due to vibration or the like, water will not enter the motor 2 through the rubber sleeve 12.

ップが脱落しても、モタ内へ水が侵入することはない。[Effects of the Invention] As described above, according to the waterproof structure of the present invention, it is possible to effectively prevent the rubber cap from falling off due to an increase in motor internal pressure when the star motor rotates internally, and to prevent the rubber cap from falling off due to vibration etc. However, water will not enter the inside of the mota.
また、ゴムスリーブ端部が導線と一体に型成形されるか
ら、製作組付は容易であり、かつ安価である。Furthermore, since the end of the rubber sleeve is molded integrally with the conducting wire, manufacturing and assembly are easy and inexpensive.
