The terminal cover 11 is a rubber waterproof cover that covers the outer periphery of the 30 terminal 7 after the terminal 8 is attached to the 30 terminal 7. As shown by a two-dot chain line in FIG. 5 (a cross-sectional view of the intermediate member 10 attached to the mold cover 2), a flange receiving portion 11a protruding inwardly is formed on the entire periphery of the opening of the terminal cover 11. And
The flange receiving portion 11a is formed on the intermediate member 10 with the flange 1
The terminal cover 11 is prevented from coming off by being locked to 0b.

Next, the operation of this embodiment will be described. The terminal 8 fitted to the terminal 7 has a pair of protruding pieces 8.
When the terminal a is fitted to the outer peripheral surface 9a of the receiving portion 9 so as to face, the movement in the rotation direction of the terminal 8 is regulated, and positioning is performed. By positioning the terminal 8 and preventing the co-rotation with the nut 13, excessive pulling of the cable 6 when tightening the nut 13 and reduction of the insulation gap with the M terminal 5 are prevented.

Further, the terminal 8 has a hexagonal outer peripheral shape of the receiving portion 9, and the intermediate member 10 on which the receiving portion 9 is formed and the mold cover 2 form an octagonal fitting structure. Positioning can be performed in multiple directions, depending on the combination of the mounting angle between the mounting member 9 and the receiving portion 9 and the mounting angle between the intermediate member 10 and the mold cover 2.

When the terminal 8 is mounted on the terminal 7, the projecting piece 8a of the terminal 8 rides on the corner of the receiving portion 9 and the mounting surface 8c of the terminal 8 rises from the receiving portion 9. Through the mounting surface 8c
The protruding length of the 30 terminal 7 protruding from the hole 8b is reduced.
As a result, it is possible to tighten the nut 13 on the terminal 30.
Since it cannot be performed , it is possible to prevent the nut 13 from being erroneously assembled.

[0019]

According to the present embodiment, the cable 6 can be mounted in various directions according to the positioning angle of the terminal 8, and even if the mounting direction of the cable 6 differs depending on the type of vehicle, the cable 6 can be mounted as in the conventional case. There is no need to prepare various types of magnet switches according to the mounting direction of the device, and it can be easily handled.

In the conventional magnet switch, since the terminal is positioned by the notch formed in the peripheral wall of the cylindrical portion, it is necessary to form the peripheral wall of the cylindrical portion on which an excessive force acts when attaching and detaching the nut thick. Since the cylindrical portion is arranged on the outer periphery of the magnet switch, the 50 terminals adjacent to the cylindrical portion or its peripheral portion may protrude from the outer periphery of the magnet switch and may interfere with other components.

On the other hand, the magnet switch 1 of the present invention
Since the receiving portion 9 engaging with the projecting piece 8a of the terminal 8 is provided inside the projecting piece 8a to receive a compressive load from the projecting piece 8a when the terminal 8 is attached or detached,
The peripheral structure of the 0 terminal 7 can be made smaller than before. Therefore, there is room in the space around the 30 terminals 7,
The 50 terminals 3 and their peripheral portions can be arranged without protruding from the outer periphery of the magnet switch 1.

When the protruding piece 8a of the terminal 8 rides on the corner of the receiving portion 9, erroneous assembly of the nut 13 can be prevented. The mounting failure can be easily determined.

Since the terminal cover 11 is fixed around the entire circumference, the terminal cover 11 can be more securely prevented from coming off as compared with a partially fixed conventional product.
