Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement of an electronic device housing, and particularly relates to the attachment of a cover.

[Prior Art] FIG. 2 is an exploded perspective view showing a conventional method of attaching a cover to a housing of an electronic device.

1 is a cover, 2 is a housing case, 3 is a screw hole provided in a folded part 4 formed on the top surface of the housing case 2, 5 is a through hole for a set screw 6, and 7 is a cutout in the housing case 2. be.

In the above configuration, the housing case and cover are cover 1.
It is assembled by placing the folded part 4 on the folded part 4 and connecting it to the screw hole 3 with the set screw 6 through the through hole 5.

[Problems to be solved by the invention] In the conventional structure described above, the head of the set screw 6 is visible on the cover 1, which spoils the aesthetic appearance, requires time to attach and detach the cover, and furthermore, cannot be disassembled in the event of a failure without tools. There were some drawbacks.

The present invention was developed in view of this situation, and is configured so that the housing case and the cover are connected only by engagement and fitting, eliminating the need for set screws.
The object of the present invention is to provide an electronic device casing that has a beautiful appearance and does not require tools for attachment and detachment.

[Means for Solving the Problems] The present invention provides an electronic device housing composed of a housing case and a cover, which includes folded portions formed on two mutually opposing sides of the upper surface of the housing case;
a notch provided in the folded portions on the two sides and having a side surface parallel to the inner surface of the housing case; and an inner surface of the housing case that is connected to one of the folded portions on the two sides. The distance between the fixing plate provided on the fixing plate, the fixing mechanism provided on the fixing plate, and the side surface provided on the back surface of one end of the cover that abuts both sides of one of the notches is equal to the distance between both sides of the notch. a protrusion slightly smaller than the interval between the two; a fixed mechanism fixed to the protrusion and capable of engaging with the fixing mechanism; The engaging portion has a step portion in which the distance between the abutting side surfaces is slightly smaller than the distance between both side surfaces of the notch, and the step portion is stepped inward by the thickness of the folded portion.

[Function] The movement of the cover in the vertical and horizontal directions is restricted by engagement with the housing case by the step portion and folded portion of the engagement portion, and engagement by the catch and strike. Furthermore, since the distance between the side surfaces of the engaging part and the protruding part is made to be slightly smaller than the respective widths of the notches to be inserted, the engaging part and the protruding part are respectively engaged with the folded part with the notch. At the same time, movement in the front and rear directions is also restricted.

[Example] Fig. 1 is an exploded perspective view of an embodiment of the present invention, Fig. 3 is a completed perspective view, Fig. 4 is a central sectional view before the cover is attached, and Fig. 5 is a central sectional view after the cover is attached. be.

The structure of the embodiment of the present invention will be explained with reference to FIGS. 1, 4, and 5. The difference from the conventional example shown in FIG. Cuts 8a and 8b are further provided in the folded portions 4 and 4 forming the sides. A fixing plate 9 is provided on the inner surface of the housing case 2 having the folded portion 4 provided with one notch 8a, and protruding parallel to the upper surface of the housing case 2. A catch 10, which is a fixing mechanism fixed by fitting, is provided on the upper surface of the fixing plate 9. A protrusion 13 having a width slightly smaller than the width of the notch 8a is provided on one end side of the back surface of the cover 1, and the protrusion 13 has a strike which is a fixed mechanism that engages with a catch 10 provided on the fixing plate 9. 12 are fixed by fitting. There is a notch 8b on the other end of the back surface of the cover 1.
An engaging part 11 having a width slightly smaller than the width of the engaging part 11 is provided, and a plate of the folded part 4 is provided at the end of the engaging part 11 so that the folded part 4 is sandwiched between the cover 1 and the engaging part 11. A stepped portion 14 is provided which is stepped inward by the thickness. Furthermore, the notch 8a
A concave portion is provided between the cover 1 and the corner of the upper surface of the housing case 2, and a constricted portion 15 for removing the cover 1 is provided.

The above-mentioned catch 10 and strike 12 mesh or fit together as a pair, and are coupled to each other by the engagement force between the catch 10 and the strike 12, or the magnetic force of mutually attracting magnets provided on the catch 10 and the strike 12. There is.
There are various methods for attaching the catch 10 and strike 12 to the housing case 2 and cover 1, such as screwing, gluing, and fitting, but here we will discuss how to take advantage of the effect of this invention, which eliminates the need for screws, and to ensure reliable attachment. A mating type is used.

The housing case and cover configured as described above are assembled in the following manner.

In FIG. 4, the cover 1 slides on the upper surface of the folded portion 4 of the housing case 2 from the direction in which the engaging portion 11 is provided. As the cover 1 moves in, the engaging part 11 provided on the back surface of the cover 1 is inserted into the notch 8b, and the stepped part 14 engages with the folded part 4 in between. In this state, if one end of the cover 1 provided with the protrusion 13 is pressed from above,
A catch 10 fitted to the fixed plate 9 and a strike 12 fitted to the protrusion 13 come into contact with each other. When pushed down further, the catch 10 and the strike 12 engage with each other and are in a fitted state, whereby the housing case 2 and the cover 1 are fixed as shown in FIG.

At that time, the cover 1 is engaged with the housing case 2 by the engaging part 11 and the folded part 4, and the catch 1 is
0 and the strike 12, movement in the vertical and horizontal directions is restricted. Furthermore, since the protruding part 13 and the engaging part 11 are made to have a width that is very slightly smaller than the width of each of the notches 8a and 8b, the engaging part 11 is formed on the side surface of the notch 8b, and the protruding part 13 is formed on the side surface of the notch 8a. The movement in the front and back direction is also restricted by contacting the sides of the

With the above steps, the cover 1 is completely fixed to the housing case 2 with the screw heads not visible, as shown in FIG.

If you want to increase the fixing force of cover 1,
Alternatively, if the size of the notched side of the cover 1 is large, increase the number of catches 10 and strikes 12 provided on the protruding part 13 and arrange them in the longitudinal direction of the notched side, or divide the protruding part 13 and make the notches. This can be achieved by abutting both sides of 8a and 8b, providing strikes on each divided protrusion, and providing a catch corresponding to each strike on the housing case.

In addition, when the distance between the engaging part 11 and the protruding part 13 is large, a plurality of protruding parts 1
3. By providing the fixing plate 9, the catch 10, and the strike 12, lifting of the center part can be prevented.

Next, the cover can be easily removed by inserting a fingertip into the constriction part 15 provided on the folded part 4 and pulling up the cover 1 as shown in FIG. If the design allows, the work will be made easier if a handle or the like is embedded in the cover.

In this embodiment, the cover 1 has been described as a mere cover for the cutout 7, but a part or all of it may be provided with other mechanisms such as a filter, a fan, a handle, etc.

[Effects of the invention] As described above, the electronic device casing of the invention does not require set screws, so anyone can easily attach and remove the cover at any time, without damaging the appearance and without the need for tools. It can be performed.
