Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to the structure of a built-in device for a unit for electrical equipment.

(Prior Art) Conventionally, as shown in Fig. 3, the structure for attaching a unit such as a wireless tuner unit to the front panel of an electrical device is to attach a flange c of a unit holder b to the back side of a front panel a with a screw d. and then insert the tuner unit e through the opening f in the front panel and the opening g in the unit holder.
Then, a structure is adopted in which a lid body i lined with an elastic body h is screwed.

(Problem to be solved by the invention) In such a structure, it is necessary to screw the unit holder to the front panel a and screw the lid i of the tuner unit e, and the number of screws increases. , It takes time to tighten the screws, and the assembly work efficiency is low.

The present invention has been made in view of the above, and aims to provide a structure of a device for assembling a unit for electrical equipment, which has a small number of screwed parts for the unit holder and the lid to the front panel, and has good assembly workability. .

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention has a fitting hole drilled in the front panel into which a unit holder for storing a unit for electrical equipment is fitted, and a fitting opening in the front panel. A structure of a device for incorporating a unit for electrical equipment by inserting a unit holder into an insertion opening,
An engaging hole and a screw receiving hole are provided on both sides of the fitting opening in the front panel, and a box portion of the unit holder to be inserted into the fitting opening is formed by a bottom plate, a side plate, and a top plate. The front end of the side plate of the unit is bent outward in the left-right direction to form left and right flanges, and the left and right flanges are provided with notches and configured to abut against the front surface of the front panel, Expanding pieces are formed on the front of the bottom plate and the top plate of the holder, the tips of which are curved downward and upward, and expand on the back side of the front panel, and the outer edges of each flange of the unit holder are bent rearward. an engagement piece extending parallel to the side plate and fitting into the engagement hole of the front panel;
A lid body with a screw insertion hole drilled therein and an elastic material attached to the back surface that contacts the unit allows the screws passed through the screw insertion hole of the lid body and the notches of the left and right flanges to be inserted into the left and right flanges. It is characterized in that it is attached together with the unit holder by screwing a screw passed through the notch into a screw receiving hole in the front panel.

(Function) Insert the unit holder into the insertion opening on the front panel, fit the engagement piece of the flange into the engagement hole on the front panel, and press the flange strongly against the front panel, then the front end of the expansion piece expands at the rear of the front panel, and the unit holder is attached to the front panel. Then, the lid body is brought into contact with the front side of the front panel, and screws are applied from the screw insertion holes of the lid body through the notches of the left and right flanges, and the screws are screwed into the screw receiving holes of the front panel. Then, the lid body is attached to the front panel together with the unit holder.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

In FIGS. 1 and 2 showing the structure of a unit built-in device for electrical equipment, 1 is a front panel;
A fitting opening 4 for fitting the unit holder 2 is opened.

On both sides of the insertion opening 4 of the front panel 1, there are engagement holes 5a, 5b into which the engagement pieces 14a, 14b of the unit holder 2 are engaged, and lid mounting screws 20a,
Screw holes 6a and 6b into which the screws 20b are screwed are provided. Further, the front portion of the insertion opening 4 is covered by the lid 3.

The unit holder 2 includes a bottom plate 7, a side plate 8
A, 8b and the upper plates 9a, 9b form a box part 10, and the front part of the box part 10, that is, the front part of the bottom plate 7 and the upper plates 9a, 9b, is cut out between the side plates 8a, 8b. Expansion pieces 11a, 11b, 12a, and 12b whose tips are curved upward and downward are provided.

At the front portions of the side plates 8a and 8b of the unit holder 2, flanges 13 are bent outward in the left and right direction.
a, 13b are provided, and the flanges 13a, 13
Engagement pieces 14a, 14b are formed on a part (upper part) of the outer end of b, which are bent further rearward and extend parallel to the side plates 8a, 8b. Flange 1
3a, 13b are screws 20a, 20 when tightening.
Notches 15a and 15b are provided through which portions b pass through.

The distal ends 11c, 11d, 12c, 12d of the expansion pieces 11a, 11b, 12a, 12b are located on the rear side of the rear surfaces 13c, 13d of the flanges 13a, 13b by about the thickness of the front panel 1. Furthermore, a notch 7a is provided at the front of the bottom plate 7, and a rear side plate 8c is provided at the rear.

The outer periphery of the lid 3 is bent backward, and screw insertion holes 16a and 16b are formed on the left and right sides,
An elastic material 19 is attached to the back surface of the lid 3 to be press-fitted to the knit 18.

Note that the engaging portion having an engaging hole that protrudes from the center of the lower front side of the unit 18 is for hooking the tip of a screwdriver etc. when pulling out the unit 18, and correspondingly, the above-mentioned unit holder A notch 7a is formed.

Next, the procedure for assembling it into the front panel 1 will be explained. First, the box portion 10 of the unit holder 2 is inserted from the front side into the fitting opening 4 provided on the front panel 1, and the flanges 13a, 13 of the unit holder 2 are
The engaging pieces 14a, 14b provided in the front panel are fitted into the engaging holes 5a, 5b of the front panel.

Then, by strongly pressing the flanges 13a, 13b against the front surface of the front panel 1, the expansion pieces 11a,
11b, 12a, 12b are reduced in the vertical direction and pass through the fitting opening 4, and expanded in the vertical direction on the back side of the front panel 1 to form the flange 1.
3a, 13b and expansion pieces 11a, 11b, 12a,
12b and the front panel 1 is held between them,
The unit holder 2 is attached to the front panel 1 (see FIG. 1).

Thereafter, by inserting the unit 18 into the unit holder 2, the rear terminal 21 of the unit 18
is connected to a connector 22 provided at the rear of the unit holder 2.

Subsequently, the lid body 3 is brought into contact with the front part of the front panel 1, and the screws 20a, 20b inserted through the screw insertion holes 16a, 16b are screwed into the screw receiving holes 6a, 6b through the notches 15a, 15b. A lid body 3 is attached and fixed to the front panel 1. In this state, the elastic material 19 on the back side of the lid 3 is connected to the unit 21.
The unit 18 is in elastic contact with the front side, and its elastic force protects the unit 18 from vibrations and shocks.

(Effects of the invention) As described above, in this invention, the screws for attaching the unit holder and the lid to the front panel are shared, so there are fewer screws for the unit holder and the lid to the front panel. Therefore, it is easy to assemble. In addition, the expansion piece and flange of the unit holder restrict the movement of the unit holder in the front and rear directions, and the locking piece that engages with the engagement hole in the front panel restricts the movement of the unit holder in the vertical and horizontal directions. Rotation is restricted and the expansion piece will not come off inadvertently.
