[Problems to be Solved by the Invention] Incidentally, in recent years, reducing man-hours has become a major theme in the manufacturing industry. Focusing on this need, we developed the DI of the DIN standard, as shown in Figure 3, which has traditionally been used in Europe.
By attaching it to the N rail 6, we are trying to reduce the number of man-hours required.

[0005] For this purpose, the mounting claw 4 and the DIN rail 6 are
It would be possible to manufacture a circuit breaker body 1 that can be used for both, but since this would require major design changes, it would be possible to use a mounting tool (adapter) for mounting the DIN rail 6, which is still a small percentage. It's a good idea.

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a device that is inexpensive, easy to attach and detach, and allows a circuit breaker to be attached to a DIN rail.

[0007]

[Means for Solving the Problems] A circuit breaker mounting device according to the present invention has a rigid claw part and an elastic claw part that are locked in a mounting claw hole of a circuit breaker main body, mutually on one side. A fixing claw portion is provided with bases formed to face each other, and is fixed to one edge side of the DIN rail on the other side of the base;
A movable claw portion disposed opposite to the fixed claw portion and locked to the other edge of the DIN rail is provided, and the movable claw portion is attached in a direction in which it is pressed toward the other edge side of the DIN rail by an elastic body. It is something that strengthens.

[0008]

[Function] In the circuit breaker mounting device of the present invention, the circuit breaker body is disposed between the rigid claw part and the elastic claw part by utilizing the elastic deformation of the elastic claw part to interrupt the circuit. The circuit breaker is attached to one side of the base by locking the rigid claw part and the elastic claw part into the mounting claw holes of the device body.

Then, by moving the movable claw portion against the biasing force of the elastic body, one edge side of the DIN rail is locked to the fixed claw portion while widening the distance between the fixed claw portion and the movable claw portion. By locking the other edge of the DIN rail with the movable claw, the movable claw is pressed against the other edge of the DIN rail by the elastic body, and the circuit breaker body is attached to the DIN rail.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In this embodiment, the collective type circuit breaker main body 1 for distribution board shown in FIG.
The case of mounting on IN standard mounting rail) 6 will be explained.

In FIG. 1, reference numeral 7 denotes a base integrally molded from plastic, and one end of one side of the base 7 has a claw hole for mounting the circuit breaker main body (see reference numeral 2 in FIG. 2).
Circuit breaker mounting claw portion (rigid claw portion) 7a that is locked to
At the other end of the same plane, a circuit breaker mounting claw (elastic claw part) 8 is attached by a rivet 11 so as to face the claw part 7a.

The circuit breaker mounting claw 8 is formed of an elastic material so that it can be elastically deformed, and includes a protrusion 8a that is locked in the mounting claw hole of the circuit breaker body, and a protrusion 8a that is engaged when the circuit breaker body is removed. The circuit breaker mounting claw 8 is configured to have a knob portion 8b used to elastically deform the circuit breaker mounting claw 8.

On the other hand, in the center of the other side of the base 7, there is a D
A DIN rail mounting claw portion (fixed claw portion) 7b that is locked to one edge of the IN rail is formed, and this claw portion 7
A DIN rail presser (movable claw portion) 9 is provided facing the DIN rail and locked to the other edge of the DIN rail.

[0014]The DIN rail presser 9 is attached to the base 7.
direction (in which direction) is inserted into a groove (not shown) formed in the
(in the figure, rightward). The DIN rail presser 9 also has a claw portion 9a that is locked to the other edge of the DIN rail, and a DIN rail retainer 9 that is attached to the DIN rail when the base 7 is removed from the DIN rail.
A knob portion 9b used to move the IN rail presser 9 against the biasing force of the elastic body 10 is formed.

Next, the operation of the apparatus of this embodiment will be explained. When installing the circuit breaker main body on the DIN rail, first insert the claw part 7a of the base 7 into one of the mounting claw holes of the circuit breaker main body, and while applying a little force to the circuit breaker main body, push it in the opposite direction. Insert the circuit breaker mounting claw 8 into the mounting claw hole on the side.
Insert the protrusion 8a using its own elastic deformation,
Attach the circuit breaker body to one side of the base 7.

Then, the DIN rail mounting claw portion 7b of the base 7 is locked to one edge of the DIN rail, and force is applied to move the DIN rail presser 9 against the biasing force of the elastic body 10, so that the claw portion By widening the distance between the DIN rail holder 7b and the DIN rail holder 9 and locking the claw part 9a of the DIN rail 9 on the other edge side of the DIN rail, the DIN rail holder 9
The other edge of the DIN rail is pressed by the elastic body 10, and the circuit breaker main body is attached to the DIN rail.

On the other hand, when removing the circuit breaker main body,
By pressing the knob 8b of the circuit breaker mounting claw 8,
Either release the engagement between the mounting claw hole and the protrusion 8a and remove only the circuit breaker body, or remove the DIN rail retainer 9.
By pulling the knob 9b to the left in the figure, D
The IN rail presser 9 is moved against the biasing force of the elastic body 10, the engagement between the DIN rail and the claw portion 9a is released, and the circuit breaker main body is removed together with the base 7.

As described above, according to the circuit breaker mounting device of this embodiment, the circuit breaker main body can be mounted and removed from the DIN rail extremely easily with an inexpensive and simple configuration.

[0019]

Effects of the Invention As described in detail above, the circuit breaker mounting device of the present invention allows the rigid claw portion and the elastic claw portion to be locked in the mounting claw holes of the circuit breaker main body. The bases are formed to face each other on one side, and on the other side of the base, there is a fixing claw part that is locked to one edge side of the DIN rail, and a fixing claw part that is disposed opposite to the fixing claw part and is arranged to face the DIN rail. A simple structure in which a movable claw part that is locked on the other edge side of the rail is provided, and the movable claw part is urged in the direction of being pressed against the other edge side of the DIN rail by an elastic body, is inexpensive and easy to attach and detach. This has the effect of allowing the circuit breaker to be mounted on the DIN rail with good flexibility.
