a and 16b are formed. 17a and 17b are end plates 1
2a and 12b are screw insertion holes, and 18a and 18b are mounting screws.

The housing 1 and the mounting bracket 11a as described above,
In 11b, the width W of the guide holes 6a and 6b provided in the bottom plate 5 of the protruding portion 4 of the housing 1 is formed to be substantially equal to or slightly larger than the plate thickness t ₁ of the fittings 11a and 11b. 7 is a locking piece 15 for the mounting brackets 11a and 11b
It is formed in such a size that a and 15b can be inserted. Further, the gap g between the upper and lower end portions of the end plates 12a, 12b of the fittings 11a, 11b and the locking pieces 15a, 15b is substantially equal to the plate thickness t ₂ of the bottom plate 5 of the projecting portion 4a of the housing 1, or It is formed slightly larger. In addition, the mounting brackets 11a, 11
b has exactly the same structure, and can be used on either the left or right side by turning it upside down.

In order to mount the housing 1 on the panel using the mounting brackets 11a and 11b as described above, as shown in FIG. 4, a panel cut 21 provided on the panel 20 is provided with a case of the housing 1 from the front side. The body 2 is inserted and the flange portion 3 is brought into contact with the front surface of the panel 20. Next, one of the locking pieces 15a of the fitting 11a is inserted into the insertion hole 7a provided in the bottom plate 5 of the projecting portion 4a of the housing 1, and the bottom plate 5 of the projecting portion 4a is locked with the upper end portion of the end plate 12a. The mounting bracket 11a is moved forward while being held with the piece 15a, and as shown in FIG.
Located inside.

In this state, the mounting brackets 11a and 11b are advanced along the side wall of the housing 1 until their tips come into contact with the back surface of the panel 20, and the mounting screws are inserted into the screw insertion holes 17a and 17b of the mounting brackets 11a and 11b. 18a and 18b are inserted and screwed into a screw hole 22 provided in the recess 4b of the housing 1. The heads of the mounting screws 18a and 18b are attached to the mounting brackets 11a and 11
When tightened to the end plates 12a, 12b of b, the panel 20 is sandwiched between the mounting brackets 11a, 11b and the flange 3 of the housing 1, and the housing 1 is firmly attached to the panel 20. The state at this time is shown in FIG.

In the present embodiment, as described above, the width W of the guide holes 6a, 6b is formed to be substantially equal to or slightly larger than the plate thickness t ₁ of the fittings 11a, 11b, and the end plates 12a, Since the gap g between 12b and the locking pieces 15a, 15b is formed to be substantially equal to or slightly larger than the plate thickness t ₂ of the bottom plate 5 of the projecting portion 4 of the case body 2, the mounting screws 15a,
When the 15b is screwed in, the horizontal movement or vertical movement of the mounting brackets 11a, 11b can be restricted, and the mounting brackets 11a, 11b can be moved straight.

When the mounting brackets 11a and 11b are inserted into the guide holes 6a and 6b, the mounting brackets 11a and 11b are held in that position, so that the mounting screws 18a and 18b are screwed into the screw holes 22. There is no need to specially provide a holding means or a positioning means for the fittings 11a and 11b. Further, the locking pieces 15a, 15b of the mounting brackets 11a, 11b,
Since 16a and 16b are provided on the upper and lower sides of the end plates 12a and 12b, one kind of mounting metal fitting is used for the left and right mounting metal fittings 11a and 11b.
Can be used as

In the above description, the case where the protruding portion 4a is provided on the upper rear surface of the housing 1 has been shown, but depending on the printed circuit board and electric parts housed inside, the protruding portion is provided on the lower rear surface or near the central portion of the rear surface. Sometimes. When the protruding portion 4a is provided on the lower portion of the rear surface of the housing 1, the top plate has guide holes 6a,
6b and the insertion holes 7a and 7b may be provided. When the protrusion 4 is provided near the center of the rear surface of the housing 1, the bottom plate or the top plate is provided with the guide holes 6a and 6b and the insertion holes 7a and 7b. Just do it.

Further, the case where only the rear end portions of the fittings 11a and 11b are bent to form the end plates 12a and 12b is shown, but the tip portions of the long pieces 13a and 13b are connected to the end plates 12a and 12b.
You may bend in the direction opposite to b, and may provide a contact piece. Thereby, the contact area with respect to the panel 20 is increased, and the housing 1 can be mounted on the panel 20 more reliably. Furthermore, although the case where the locking pieces 15a and 15b are provided above and below the end plates 12a and 12b of the fittings 11a and 11b is shown, the locking pieces may be provided only above the end plates 12a and 12b.
However, in this case, it is necessary to prepare two types of left and right mounting brackets. Further, if the thickness t ₂ of the case main body 2 is thin, L from the bottom plate 5 of the projecting portion 4a toward the rear of the recess 4b
A character-shaped contact plate may be attached, and guide holes 6a and 6b and insertion holes 7a and 7b may be provided in both the contact plate and the bottom plate 5.

【The invention's effect】

(1) A mounting device for a housing according to the present invention has a projecting portion and a recessed portion on the rear surface side, a guide hole that is long in the front-rear direction in the vicinity of both sides of a bottom plate or a top plate of the projecting portion, and a width that is wider than the guide hole in the rear portion. The housing has a wide insertion hole continuously formed and screw holes near both sides of the vertical wall of the recess, and the end plate with the screw insertion hole and both ends of the end plate are bent at substantially right angles in the same direction. And a mounting piece having a locking piece formed by bending at least one of the upper and lower sides of the short piece toward the long side and inserting the locking piece of the mounting bracket into the insertion hole of the housing. , Hold the bottom plate or top plate of the protruding part of the housing by the end plate and the locking piece to move it forward, insert the mounting screw into the screw hole provided in the end plate of the mounting bracket, and attach this mounting screw to the housing. Since the panel is pinched by the flange of the housing and the mounting bracket, it is screwed into the provided screw hole. No protrusion into the housing since it is not necessary to provide a groove or the like, inside can be effectively used, the positioning of the upper mounting bracket, mounted, so fixing even simple, can be shortened installation time.

(2) Further, since the locking pieces are provided above and below the short piece of the mounting bracket of the above (1), one type of mounting bracket can be used for both right and left. For this reason, the die for press-fitting the mounting bracket becomes inexpensive, and not only the cost can be reduced, but also inventory control and process control are extremely easy.

(3) Further, the width of the guide hole provided in the casing of the above (1) or (2) is formed to be substantially equal to or slightly larger than the plate thickness of the fitting, and the end plate of the fitting is formed. Since the gap with the locking piece is formed to be approximately equal to or slightly larger than the thickness of the bottom plate or the top plate provided with the guide hole, when the mounting bracket is advanced along the side wall of the housing, the mounting bracket is It can move up and down or left and right, and can go straight, so that the housing can be securely attached to the correct position.
