This accomplishes a cheap mounting device (adapter) for DIN rail with which mounting and removal can be made efffectively.

Description

[Detailed description of the invention] [Industrial application field] This invention relates to a circuit breaker mounting device.

[Conventional technology]

Figure 2 is a perspective view of a collective type circuit breaker for lighting distribution boards specified in JKM 1292. The claw hole, (3) is the mounting panel, (4 is the mounting claw, and (5) is the screw.

To attach to the mounting panel (3), use the mounting claws (4 claws (4 &
) into the mounting claw hole (2) of the circuit breaker body (1), and then tightened the screw with the opening.

[Problem to be solved by the invention]

In recent years, reducing man-hours has become a major theme in the manufacturing industry. As shown in Fig. 3, which has been conventionally used in
We are trying to reduce the number of work hours by installing the standard DIN rail (0).
It is possible to manufacture a circuit breaker body (1) that is compatible with both DIN Ray fL/(6) and DIN Ray fV(6), but this requires a major design change. Therefore, it is a good idea to use a mounting tool (adapter).

As mentioned above, this invention uses a collective type circuit breaker for a distribution board as a DI.
The object of the present invention is to provide a circuit breaker mounting device (adapter) for mounting on an N rail that is inexpensive and has good attachment/detachability.

[Means for resolving issues]

The circuit breaker mounting device according to the present invention is integrally molded of plastic, has two circuit breaker side claws at both ends for mounting the circuit breaker, and has at least one of the circuit breaker side claws. It has elasticity to improve attachment and detachment, and a knob is provided to make it easier to remove the circuit breaker by hand. Also, in the center on the opposite side of the circuit breaker side claw, there are two pieces for mounting on a DIN rail. The rail A74'Il has a claw portion, and at least one of the rail side claw portions is made elastic.

[Effect]

In this invention, after the two circuit breaker side claws provided at both ends are attached to the mounting claw holes of the circuit breaker using the elasticity provided on at least one side, the DI
Two rail-side claws for mounting the N rail can be attached to the DIN rail by utilizing the elasticity provided on at least one side.

Further, when removing the circuit breaker, the circuit breaker can be removed using the knob portion of the breaker-side claw portion.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG.

In the figure, ('7) is a mounting device (adapter), which has circuit breaker side claws (7a) and (7b) at both ends, and one of the claws (7b) has a thin wall to provide elasticity. A portion (7c) and a knob portion (7d) are provided. In addition, on the back side opposite to the stool where the circuit breaker side claws (7a) and (7b) are located, a tray /L/@claw (7e) (7f>) for mounting the DIN rail is provided approximately in the center. There is,
One of the claws (7t) is provided with a thin part (7g) and a grip part (7h) to provide elasticity.

When installing, first install the circuit breaker (]) shown in Figure 2.
Insert the circuit breaker side claw part (7&) of the adapter (7) into one of the mounting claw holes (2), and insert the elastic part of the adapter (7) into the mounting claw part (2) on the opposite side while applying a little force. Insert the breaker side claw part (7b) on one side and attach the adapter (force) to the circuit breaker (1).

Next, lock one rail-side claw part (7e) of the adapter (7) for installing the CNC N rail to the DIN rail (6), and while applying force, connect the elastic claw part (7e) on the opposite side to the DIN rail (6). 7f)
to the DIN rail (6) to complete the installation.

When removing the circuit breaker (1), press the knob (7d) of the adapter (71) to release the connection between the mounting claw hole (2) and the circuit breaker side claw (7b), and remove the circuit breaker (1). or by removing the DIN adapter ('7).
The circuit breaker (1) can be removed together with the adapter (7') by releasing the engagement between the rail/L/ (6) and the rail side claw part (7f).

As in the above embodiment, since the rail-side claw part (7f) is provided with a thin wall part (7g) and a knob part (7h) to give it elasticity, when removing the adapter (7) from the DIN rail (0), This can be done easily by pressing the knob (7h).

In the above embodiment, the thin part (7c) and the knob part (7d)
may be provided on the other circuit breaker side claw portion (7d), or may be provided on both claw portions (7d) and (7b). Similarly, the thin wall M (7g) and the knob part (7h) may be provided on the other rail side claw part (7e), or both the claw parts (7h) may be provided on the other rail side claw part (7e).
e) and (7f) may be provided. Furthermore, the knob part (
7h) may be a can.

〔Effect of the invention〕

As described above, the present invention has the effect of providing an inexpensive mounting device (adapter) for mounting the N-rail that is easy to attach and detach.

FIG. 1 is a perspective view showing a mounting device according to an embodiment of the present invention, FIG. 2 is a perspective view showing a collective type circuit breaker for a distribution board,
FIG. 3 is a perspective view showing a DIN rail of the D/IJ standard.

In the figure, (force is the attachment device, (7a), (7b
) is the breaker side claw part, (7cL), (7h) is the knob part,
(7s) and (7f) are Ray/L' stool claw parts.
