要として組付がめんどうで、プランジャ3も接点圧スプ
リング16を収納するスペースを必要とするので、軸方
向に長くなり構造が複雑になる。Conventionally, a magnet switch for a starter has had a configuration as shown in FIG. That is, the movable contact 10 fixed to the plunger 3, which is attracted by an undisclosed coil when energized, is held between an insulating plate 15 and an insulator 17, and the insulator 17 is further pressed by a contact pressure spring 16 held by a washer plate 18. There is. Therefore, when the plunger 3(1) is attracted, the contact pressure spring 16 is compressed, and the movable contact 10 is pressed against a fixed contact (not shown) with contact pressure. And Nippondenso Public Technical Report JAN 19
80 No. 17 If the structure is as shown in reference number 17-058, the washer plate 18 requires welding to fix, making it troublesome to assemble, and the plunger 3 also requires space to accommodate the contact pressure spring 16. It becomes longer in the axial direction and the structure becomes more complicated.

る。In order to solve the above-mentioned drawbacks, the present invention provides an elastic body with insulation properties to support and fix the movable contact to the plunger, thereby improving the assemblability of the starter magnetic switch, reducing the number of parts, and making it smaller. This is the purpose.

点IOを固定接点12へ圧接して接点間の接触を完全な
ものとし、さらに衝突時の衝撃を緩衝させている。Next, the operation of the above configuration will be explained. When a key switch (not shown) is closed from the non-energized state shown in FIG. 3, first, the coil 9 is energized and a magnetic force acts, and the plunger 3 is attracted. The plunger 3 compresses the return spring 14 and is sucked until the movable contact 10 collides with the fixed contact 12 and stops. At that time (3), the contact pressure insulating spring 15 uses its elasticity to press the movable contact IO against the fixed contact 12 to complete the contact between the contacts and further buffer the impact at the time of collision.

チが開かれるとコイル9に生じていた磁力が消勢され、
プランジャ3はリターンスプリング14によって復帰さ
せられて初期の非通電状態に戻る。In this way, the movable contact 10 and the fixed contact 12 are closed, and the motor of the starter (not shown), in which the plunger 3 is held, is energized to perform cracking. Next, when a key switch (not shown) is opened, the magnetic force generated in the coil 9 is deenergized.
The plunger 3 is returned to its initial non-energized state by the return spring 14.

ったため、軸方向の長さも必要最小限の長さで済む。さ
らに溶接にかわって、絞め固定を採用したので組付も容
易になる。The contact pressure insulating spring 15 insulates the movable contact 10 and presses the contact, eliminating the need for the conventional contact pressure spring 16, so that the length in the axial direction can be kept to the minimum necessary length. Furthermore, it is easier to assemble because it uses tightening instead of welding.

型化できるという優れた効果がある。As described above, according to the present invention, by providing an elastic body with insulating properties to support and fix the movable contact to the plunger, ease of assembly is improved by employing tightening fixing, and the elastic body is insulated. (4) Since the contact pressure spring is eliminated and the number of parts is reduced, the length in the axial direction can be kept to the minimum necessary, which has the excellent effect of reducing weight and size.
