Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for electronic equipment, and more particularly to a mounting mechanism for electronic equipment for mounting an electronic equipment case on a din rail.

[0002]

2. Description of the Related Art As a conventional method for mounting an electronic device case on a din rail, as shown in FIG.
There is a method of fixing the electronic device case 30 mounted by sliding from one end with a screw 32 or the like, or a method of using a sliding locking portion. As a method of fixing with a screw, there are a method of preparing a screw hole for screwing the screw on the din rail side, and a method of directly pressing the screw against the din rail and locking with a frictional force. Further, as a method of using the sliding locking portion, there is a method of sliding the locking portion using an elastic body such as a spring.

[0003]

Among the conventional mounting structures for electronic equipment to the din rail, the type of mounting to the din rail using a screw is one in which the electronic equipment case is inserted into the din rail from one end of the din rail, The screw must be fixed to the din rail using a separate tool such as a screwdriver, and once fixed, the equipment case can be moved by loosening the screw using the screwdriver and then moving the screwdriver again. There was an inconvenience that it had to be fixed using.

Further, in the mounting mechanism using a sliding locking portion using a spring or the like, since the locking portion slides when the din rail is mounted, unlike the method of mounting the electronic equipment case by screws or the like, the din rail The electronic device case can be attached from any place. However, since the mechanism of the locking portion must have a structure incorporating an elastic body such as a spring, the structure becomes complicated, and the disadvantages of increasing the number of parts and increasing the cost are met.

An object of the present invention is to provide a mounting mechanism for an electronic device, which enables a quick and reliable mounting of the electronic device on the din rail and has a simple structure.

[0006]

According to the present invention, there is provided a mounting mechanism for an electronic device, which is substantially rectangular, in which one line in the longitudinal direction of the upper end face is slanted, and the other edge in the longitudinal direction is the din. A slide plate that is cut out so as to accommodate the end of the overhang portion of the rail, and a din that accommodates the din rail and has a locking groove that locks one of the overhang portions of the din rail in the upper knuckle portion. A rail groove and a slide plate groove that is continuous with the din rail groove at the center of the din rail groove and is orthogonal to the din rail groove downward and accommodates the slide plate. When the slide plate is accommodated in the slide plate, and one of the overhangs of the din rail is locked in the locking groove, the other overhang of the din rail is not applied when downward force is not applied to the slide plate. Bottom edge of When the case body that can press the one edge of the slide plate and the slide plate is housed in the slide plate groove and then the slide plate is pushed down, the slide plate is returned to the original position. It has a spring mechanism that applies an upward force to return to the slide plate.

[0007]

First, the slide plate is housed in the slide plate groove of the case body. Next, engage the locking groove of the din rail groove of the case body with the overhanging portion above the din rail,
Rotate the case body and press one edge of the upper part of the slide plate against the overhanging part below the din rail. When the case body is further rotated, the overhanging portion pushes down the slide plate against the spring force of the spring mechanism, and goes over the upper end surface of the slide plate. When the other overhanging portion of the din rail contacts the bottom surface of the din rail mechanism, the other overhanging portion of the din rail is locked in the groove formed by the other edge of the slide plate and the din rail groove. As a result, the electronic device is attached to the din rail.

According to a second aspect of the present invention, the spring mechanism has a protrusion provided on the bottom surface of the slide plate groove and an opening formed from the front surface to the back surface of the slide plate so as to extend outward from each other downward from above. The pair of spring portions extend and extend between the protrusions, and the slide plate is pushed downward in the slide plate groove to extend the protrusions.

According to the third aspect, two sets of the spring mechanisms are provided in the left and right direction of the slide plate.

According to the fourth aspect of the present invention, the slide plate is provided with a projection escape groove for allowing the projection to enter the opening.

According to the fifth aspect of the present invention, the engaging grooves are formed at both corners in the vertical direction of the slide plate groove, and the engaging portions for engaging with the engaging grooves are provided at both longitudinal end faces of the slide plate. Has been formed.

According to the sixth aspect, a tongue-shaped portion elastically displaced in a direction perpendicular to the groove is formed at the bottom of the slide plate groove, and the slide plate is fixed on the tongue-shaped portion so that the slide plate is used for the slide plate. The tongue is pushed by being inserted into the groove and being pushed down, and the stopper that enters the opening formed in the slide plate by the elastic force of the tongue is fixed.
