リブ３が設けられている。 Here, since the various parts that make up the contactor are not directly related to the present invention, only a brief explanation will be given.
The contactor in FIG. 2 consists of a frame 6 that holds an insulating frame 2 and a bottom plate, and a vacuum switch valve (hereinafter simply referred to as a valve) provided in the insulating frame 2.
8, a coupler 9 that connects the valve 8 and a suction plate movable by the attraction of the coil, and a high voltage section 1 drawn from both poles of the valve 8. Also the third
In the figure, the frame is divided into a frame that houses the valve and a frame that houses the device that moves the valve, and the former frame, that is, the insulating frame 2'
A valve 8 is provided inside the insulating frame 2', a high voltage section 1 is arranged above and below the bulb 8, and ribs 3 having holes 4' are provided at the four corners of the insulating frame 2'. It is being

ずと大きさが決まつてしまう。 Thus, the contactor shown in FIG.
Since a high voltage is applied to the frame 6, there is a risk of leakage to the frame 6 if the distance E is short. Therefore, it is necessary to take a long distance E. This makes it impossible to reduce the size and weight of the contactor, and the size is naturally determined by the necessary and sufficient insulation distance.
これに対処するために、フレームの一部を絶縁
物化したものが第３図に示されるものである。 In order to cope with this problem, a part of the frame is made of an insulating material, as shown in FIG.

However, as shown in FIG.
Minimum distance C from high voltage part 1 due to danger etc.
You need to release only D. Although this allows the device to be smaller and lighter than the one shown in FIG. 2, it is still not sufficient.
そこで本考案は、上述したような欠点を解消す
