[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal mounting device applied to an electromagnetic contactor or the like.

[0002]

2. Description of the Related Art Conventionally, there has been a terminal mounting device in which a side surface of an L-shaped terminal plate extending over an upper surface and a side surface of a body of an electromagnetic contactor is screwed and connected to a fixed contact mounted inside the body (for example, see, for example). No. 2-12670).

[0003]

However, it is necessary to separately attach the fixed contact and the terminal plate to the body, and since the terminal plate is fixed with one screw, the upper surface of the terminal plate is easily wobble. Therefore, it is necessary to increase the interval between the terminal plates. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a terminal mounting device which can easily mount a terminal plate and a fixed contact and can firmly fix the terminal plate without fear of shaking.

[0004]

SUMMARY OF THE INVENTION The present invention is a terminal plate having a U-shape and having a terminal screw portion on the outer surface of one side piece and having a fixed contact and a screw hole for mounting on the other side piece. A first support portion for supporting the inner surface of the one side piece, and a second support portion for supporting the outer surface of the other side piece; A supporting member formed on the supporting portion, and a mounting screw screwed into the screw hole through the mounting hole, wherein the one side of the intermediate piece of the terminal plate is fixed to the first supporting portion by tightening the mounting screw. An inclined surface is formed on one of the one side piece and the first support portion, and a contact portion slidably abutting on the inclined surface is provided on the other side. Things.

[0005]

According to the structure of the present invention, one side piece of the terminal plate abuts the first support portion and the abutting portion abuts on the inclined surface, and the other side piece abuts the second support portion, and the mounting hole is provided. When the mounting screw is screwed into the screw hole through the through hole, the inclined surface and the contact portion slide with the screw tightening, and one side piece of the intermediate piece of the terminal plate is drawn to the first support portion and fixed. In this case, the mounting is simplified as compared with the conventional because of its fixed contact terminal plate, moreover the clamping engagement and mounting screws between the inclined surface and the contact portion, to fix the terminal plate to support hard solid The terminal board by tightening and loosening the terminal screws.
No wobble, no displacement of fixed contacts,
Also, the work of connecting lead wires etc. to the terminal screws is made easier.

One embodiment of the present invention will be described with reference to FIGS. That is, this terminal mounting device has a terminal plate 1, a support 2, and mounting screws 3 in FIG. The terminal plate 1 has a U-shape and has a terminal screw portion 5 on an outer surface of one side piece 4 and a fixed contact 8 and a screw hole 9 for mounting on the other side piece 7. Also one side piece 4
The inclined piece 6 is formed on the inner surface by inclining the lower folded piece 6 at the tip end of the lower part. The terminal screw portion 5 is formed by a screw through hole 19 formed in the one side piece 4, a nut 20 disposed inside the one side piece 4, and a terminal screw 21 which is screwed into the nut 20 through the screw through hole 19. Become. Further, the other side piece 7 is also inclined in the same direction as the inclined surface 10.

The support 2 has a first support 11 for supporting the inner surface of one side piece 4 and a second support 13 for supporting the outer surface of the other side piece 7. A matching mounting hole 14 is formed in the second support 13. The contact portion 12 slidably in contact with the inclined surface 10 is formed by an inclined side surface parallel to the inclined surface 10 of the groove 15 of the first support portion 11. The second support portion 13 of the embodiment is inclined along the other side piece 7, and the mounting hole 14 is formed perpendicular to the inclined surface of the other side piece 7. The side opposite to the support surface of the second support portion 13 forms an oppositely inclined surface 52.

The support 2 of this embodiment is a contact block 24 (FIG. 4) of a body 23 of an electromagnetic contactor described later. First
The nut storage part 1 for storing the nut 20 in the support part 11
6 and a screw housing portion 17 for housing the distal end portion of the terminal screw 21. The second support portion 13 has an inner lower surface formed by forming a hole 18 in the side surface of the support 2 as an example.

The mounting screw 3 is screwed into the screw hole 9 through the mounting hole 14. Reference numeral 53 denotes a guide that passes through the neck of the mounting screw 3 and slides on the inclined surface 52. In this embodiment, the one side piece 4 of the terminal plate 1 abuts the first support portion 11 and the contact portion 12 abuts on the inclined surface 10, and the other side piece 7 abuts the second support portion 13 and is attached. When the mounting screw 3 is screwed into the screw hole 9 through the hole 14, the inclined surface 10 and the contact portion 12 slide with the screw tightening, and the one side piece 4 of the intermediate piece of the terminal plate 1 is attached to the first support portion 11. Attracted and fixed.

The other side piece 7 is inclined with the screw tightening of the mounting screw 3, so that the other side 7 side of the intermediate piece also moves so as to be drawn to the second support portion 13. 3 also moves in the same direction along the inclined surface 52, so that the mounting screw 3 can be strongly tightened. According to this embodiment, mounting is simplified as compared with the conventional because of its fixed contact 8 to the terminal plate 1, moreover the clamping engagement and mounting screws 3 of the inclined surface 10 and the contact portion 12, hard solid Since the terminal plate 1 can be fixed to the support body 2 by loosening the terminal screw portion 5,
There is no wobble, and the fixed contact 8 does not displace.
Also, the work of connecting lead wires etc. to the terminal screw part 5 is easy.
