BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for mounting electrical equipment on a DIN standard rail.

[0002]

2. Description of the Related Art In order to eliminate the complexity of fixing each electric device to a panel when mounting an electric device, recently, a structure has been adopted in which each device is mounted on a long DIN rail and fixed. Is common.

As a device for mounting a device on a DIN rail, there are a device in which a coil spring is attached to a lever to provide a spring force, and a device in which a lever is integrally molded to provide a spring force.

Basically, as shown in FIG. 3 (side view) and FIG. 4 (perspective view from the bottom), each of these has a groove 2 formed in the bottom of the device main body 1 and the DIN rail 3 is formed. The lever 6 has a projection 4 formed on one wall of the groove 2 so as not to be detached from the DIN rail 3 and has a tip serving as an engaging piece 5 on the other wall of the groove 2. Spring 7
Therefore, there has been proposed an elastic piece which is formed integrally with the lever 6 instead of the spring 7 by projecting to the DIN rail 3 side (see JP-A-2-310999).

[0005]

However, in the structure in which the device is mounted on the DIN rail 3 by protruding from the outside as described above, it is necessary to widen the width of the electric device by the length of the lever, which results in a large size. Was regulated by it, and it was a barrier to miniaturization. In addition, when attaching or detaching the device, it is necessary to pull out the lever 6 to the outside with an instrument such as a screwdriver, and then attach the device main body to the rail in that state.

The problem to be solved by the present invention is to provide a device which does not need to unnecessarily widen the width of the device body and which allows the device to be attached and detached with one touch.

[0007]

In order to solve the above-mentioned problems, a rail mounting device for an electric device according to the present invention is provided with a fixed stopper at the bottom of the electric device body for engaging one locking piece of a DIN rail. A sliding groove is formed on the bottom of the electric device main body in a direction orthogonal to the longitudinal direction of the DIN rail, and a slidable lever is attached to the sliding groove, and the base end of the lever is provided with the sliding groove. A movable stopper that engages with the other locking piece of the DIN rail is formed, and the inner end of the lever is in contact with the wall surface of the main body of the electric device on the side of the fixed stopper, and in the normal state, the sliding groove is formed. A pair of elastic pieces that are wider than the width of the sliding groove and are narrower than the width of the sliding groove when compressed are integrally formed with the lever.

[0008]

[Function] From the side opposite to the side where the fixed stopper is installed,
When the lever is installed in the sliding groove provided on the bottom of the device body,
The tip of the lever projects toward the fixed stopper, and at the same time, the pair of elastic pieces also projects. In this state, push the tip of the lever,
Open the movable stopper and attach the device body to the locking pieces on both sides of the DIN rail. When the hand is released, the movable stopper approaches the main body of the device by the action of the elastic piece of the lever, engages with the locking pieces on both sides of the DIN rail, and the electric device is fixed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below based on the embodiments shown in the drawings. FIG. 1 is a diagram showing an embodiment of the present invention as seen from the bottom of a device body, and FIG. 2 is a perspective view showing the structure of a lever.

In FIG. 1, reference numeral 10 denotes an electric equipment main body, and 11
Is a DIN rail. A fixed stopper 12 that engages with one of the locking pieces 11a of the rail 11 is formed at the widthwise end of the bottom of the device body 10. In addition, the device body 1
A sliding groove 13 is formed on the bottom portion of 0 in a direction orthogonal to the longitudinal direction of the rail 11, and a lever 14 is attached to the sliding groove 13.

As shown in FIG. 2, the lever 14 has a movable stopper 15 formed at the base end thereof, and at the other end thereof, a pair of elastic pieces 16 are provided on both sides inside the lever head 17.
It is formed integrally with. The lever 14 is made of a material having an elastic force, and the elastic piece 16 has a spring property. When this elastic piece 16 is pressed down from both sides in the width direction, the lever 1
The recesses 18 are formed on both sides of the lever main body so that the recesses 18 fit within the width dimension of No. 4. Further, the tip of the elastic piece 16 is normally designed to be wider than the width of the sliding groove 13.

The lever 14 connects the device body 10 to the rail 11
The elastic piece 16 which is incorporated into the sliding groove 13 of the device body 10 before being attached to the device body is pressed against the width of the sliding groove 13 at the time of mounting. It extends beyond the width of 13 and does not come out. Lever 14
When the head 17 is pushed, the lever 14 slides against the elastic force of the elastic piece 16 and the position of the movable stopper 15 moves.

In order to mount the device main body 10 with the lever 14 mounted on the rail 11, the movable stopper 15 is opened when the head 17 of the lever 14 is sandwiched, and one side of the rail 11 is locked. The fixed stopper 12 is provided on the piece 11a, and the movable stopper 1 is provided on the other locking piece 11b.
The device main body 10 can be attached to the rail 11 by allowing 5 to engage and releasing the head 17 of the lever 14 when engaged.

To remove the device body 10 from the rail 11, when the head 17 of the lever 14 is sandwiched, the movable stopper 15 is disengaged from the other locking piece 11b of the rail 11, so if the device body 10 is pulled out, the device body 10 is pulled out. It can be removed.

[0015]

As described above, according to the present invention, the device can be made compact, and the electric device main body can be operated with one touch.
Can be attached to and removed from the IN rail. Also, the lever can be easily attached to the main body.
