The mounting bracket b includes a base c installed at a predetermined installation location, and a pair of housing mounting walls d and e erected on both opposing sides of the base c so as to face each other. Are arranged integrally in a substantially U-shape.

[0005] At the center of the upper ends of both housing mounting walls d and e, slide rails f and g bent inwardly of the base c are formed. A bent case mounting portion h is formed on the outer side of c, and a case mounting portion i extending upward is formed upright on the rear side of the upper end.

On the other hand, on both side walls j and k of the electronic device housing a, guide grooves m each having an open rear portion are formed, and one end of the guide groove m is opened outward. A mounting piece portion o is formed on the inclined guide portion n and protrudes from the other end closing side of the guide groove m.

[0007] Then, in order to mount the electronic device housing a to the mounting bracket b, first, as shown in FIG. 10, the electronic device housing a is inserted between the housing mounting walls d and e and expanded. The slide rails f and g are fitted into the guide groove m from the opening n side, and the electronic device housing a is slidably accommodated in the mounting bracket b.

At this time, the mounting hole p of the mounting piece portion o and the screw hole q of the housing mounting portion h face each other, and the screw r is inserted into the mounting hole p.
After that, the electronic device housing a was attached to the mounting bracket b by screwing into the screw hole q.

[0009]

However, in a conventional electronic device housing mounting apparatus, a screw r is used to
Since the electronic device housing a is configured to be mounted on the mounting bracket b, the operator needs to screw the screw r using a tool such as a screwdriver. There was a problem that efficiency was poor.

In view of the foregoing, an object of the present invention is to provide an electronic device housing mounting apparatus which can easily mount an electronic device housing on a mounting bracket without using screws.

[0011]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to an electronic apparatus having a structure in which an electronic apparatus housing such as an in-vehicle wireless apparatus housing is installed at a predetermined installation place via a mounting bracket. A housing mounting device, wherein a mounting bracket is installed at a predetermined installation location and stands upright so as to face each other on both opposing sides of the base portion for housing and mounting the electronic device housing. And a pair of housing mounting walls, each of which is engraved on both side walls of the electronic device housing and slides in a guide groove which is open at one end. A slide rail portion for receiving and guiding the housing of the electronic device on the base portion, and fixing means for holding and fixing the housing of the electronic device case on the base are provided. Swingable to one of the mounting walls A locking lever provided, is configured to have a locking claw portion formed on the lock lever, and,
A lock concave portion, into which a lock claw is fitted, is engraved on a side wall portion of the side wall portion of the electronic device housing opposite to one of the mounting walls so as to communicate with the other end closing side of the guide groove. ,
Furthermore, the present invention is characterized in that it has a spring for maintaining a locked state in which the lock claw portion is fitted into the lock concave portion.

According to the present invention, the slide rail portion is slidably inserted from the opening end side of the guide groove portion, and the electronic device housing is housed in the mounting bracket. When the lock claw faces the lock recess provided on the other end closing side of the guide groove, the lock lever swings by the urging force of the spring, and the lock claw is fitted into the lock recess, and the spring is attached. By the force, the fitting state of the lock claw portion to the lock concave portion is maintained,
The electronic device housing is housed and fixed in the mounting bracket.

[0013] Therefore, the conventional screw mounting operation using a tool such as a screwdriver can be eliminated, and the mounting operation of the electronic device housing to the mounting bracket can be performed efficiently.

The spring according to the present invention has one end hooked to the lock lever and the other end hooked to the mounting wall so that the lock claw contacts the lower wall of the guide groove. At the opening end of the groove portion, an inclined guide portion is formed to expand outward and guide the lock claw portion into the guide groove. As a result, when the electronic device housing is housed in the mounting bracket, the lock is formed. The claw portion first slides on the inclined guide portion at the opening end of the guide groove portion and guides the lock lever against the urging force of the spring by being guided into the guide groove portion, and is easily guided into the guide groove. Will be.

Further, according to the present invention, on the free end side of the lock lever,
By providing the cover member with a fitting, a function of protecting a worker's hand or the like when the worker swings the lock lever against a spring in order to remove the electronic device housing from the mounting bracket. become.
