Description

[Detailed explanation of the idea] (a) Industrial application fields This invention relates to a case for electronic equipment.

(b) Prior Art A conventional electronic device case A' is shown in FIG. 3.

Case A' consists of case body 1', base body 2', and name plate 7', and case body 1' is a metal plate whose cross section is omitted.
A hole (not shown) for a mounting screw 9' is provided on both side hanging pieces 1'a, 1'a, and the base body 2' is formed of a metal plate and has a substantially square cross section. The upper ends of both side pieces 2'a, 2'a are bent inward so that the lower ends of the hanging pieces 1'a, 1'a of the case body 1' can be placed, and the bent parts A screw hole (not shown) for inserting the mounting screw 9' is provided in a part corresponding to the hole (not shown) in the case body 1', and a screw hole (not shown) for inserting the mounting screw 9' is provided in a part corresponding to the hole (not shown) in the case body 1'. A side plate 2'b is integrally formed with the base body 2' at the opening, a printed circuit board (not shown) with electronic components attached is housed from the other opening, and a name plate 7 is placed at the edge of the opening. ' was attached and stored in the designated position of the electronic device.

(c) Problems that the invention aims to solve However, depending on the size of the equipment to be housed in case A', a case A' suitable for the equipment is required, and depending on the function of the equipment, it is necessary to Since case A′ is required according to the size, there is a problem that not only is a large amount of mold cost required to manufacture cases A′ of various sizes, but also inventory management becomes complicated. .

In addition, cases A' for electronic devices are manufactured using manufacturing methods such as plastic molding or sheet metal processing depending on the production volume.However, plastic molding cases are suitable for mass production because they are molded using molds, while sheet metal processing Cases are made by processing sheet metal, making them suitable for small-scale production. Therefore, when manufacturing products on a medium-scale production scale of several hundred to several thousand units, plastic molding requires the use of metal. The mold cost was too high, and sheet metal processing required too many man-hours.

(d) Means for solving the problem This invention was proposed to improve the above-mentioned problems, and this invention involves extruding aluminum to form a long aluminum material with a rough cross section, and extruding it. A side plate is formed by cutting the aluminum to a predetermined length in the direction, and the side bodies are attached to both sides of the bottom plate to form a base body with a roughly square cross section.The aluminum is extruded and formed into a long aluminum sheet with a roughly square cross section. This aluminum material is extruded and cut to the specified length of the school to form a case body, and a base body is attached to the case body so as to cover the front and side surfaces of the opening of this case body. This is achieved by a case for electronic equipment.

(e) Effect This invention uses aluminum extrusion to form a long aluminum material with a substantially square cross section, so it can be cut to any desired length to form the case body. The body is also formed into a long aluminum material with a roughly shaped cross section by extrusion molding, so it can be cut to any length, and it also covers the front and side surfaces of the opening of the case body. Since the base body has side bodies removably attached to both sides of the bottom plate, a base body suitable for the case body can be created by simply changing the bottom plate.

(f) Example Hereinafter, this invention will be explained based on an example shown in FIGS. 1 and 2.

A is a case for electronic equipment, which is composed of a case body 1 and a base body 2.

The case body 1 is made of an elongated aluminum material (not shown) with a substantially square cross section by extrusion molding.
It is formed by cutting this aluminum material (not shown) at a predetermined length L1, and has hanging pieces 1 on both sides.
The distance between the inner sides of a and 1a is L2.

Holes 1b, 1b for mounting screws 9, 9 are provided in both side hanging pieces 1a, 1a of this case body 1.

The base body 2 is formed with side bodies 3, 4 and a bottom plate 5 to have a substantially square cross section.The side bodies 3 and 4 are attached to opposite sides of the bottom plate 5, and the total length is the same as the length. It is formed to be L1.

The base body 2 is attached to the case body 1 so that the screw holes 3d and 4d of the side body 3 and the side body 4 correspond to the holes 1a and 1a of the case body 1, respectively, and also covers the opening front surface and the opening side surface of the case body 1. The mounting screws 9, 9 are screwed into the respective holes 1a, 1a.

The side body 3 and the side body 4 are made of elongated aluminum material (not shown) with a substantially L-shaped cross section by extrusion molding.
It is formed by cutting it at a predetermined length L2.

The side body 3 consists of a vertical part 3a and a horizontal part 3b, and the vertical part 3a has mounting protrusions 3c, 3c, each having a roughly shaped cross section, which are opposed to the vertical part 3a to attach the name plate 7 to the upper and lower ends of the outer wall. It is provided.

The horizontal part 3b of the side body 3 has mounting screws 9 on both side walls.
A mounting piece 3e for attaching the bottom plate 5 to the free end side wall is provided, respectively.
This mounting piece 3e is provided with holes 3f, 3f through which the mounting screws 9, 9 are inserted, and the lower side of the mounting piece 3e is used to hold the bottom plate 5 when the bottom plate 5 is attached. A holding piece 3g is provided.

The side body 4 has an external wire connection device 6 on the vertical portion 4a.
It has a mounting hole 4h for attaching the
c, screw hole 4d, mounting piece 4e, hole 4f, holding piece 4
g is formed similarly to the corresponding part of the side body 3.

The bottom plate 5 has holes 5a, 5a on both sides through which the mounting screws 9, 9, 9, 9 are inserted, respectively, and one side of the bottom plate 5 is inserted between the mounting piece 3e and the holding piece 3h of the side body 3. and the hole 3f of the side body 3,
3f and the holes 5a, 5a of the bottom plate 5 are arranged in correspondence,
Then, insert the mounting screws 9, 9 from below the bottom plate 5 into the holes 3f, 3f of the side body 3 and the holes 5a, 5a of the bottom plate 5, and screw in the nuts 10, 10 to fix the bottom plate 5 and the side body 3. are doing.

Further, the base body 2 is formed by attaching the other side portion of the bottom plate 5 to the side body 4 in the same manner as the side body 3 described above.

Then, after the printed circuit board 8 on which electronic components are attached is placed so as to span over the horizontal portion 3b of the side body 3 and the horizontal portion 4b of the side body 4, the base body 2 is placed on the case body 1. Ru.

In this case, the bottom plate 5 is used such that the length of the base body 2 is L1 relative to the length L1 of the case body 1, but since the side bodies 3 and 4 are removable, By preparing bottom plates 5 of various lengths, cases of various lengths can be formed.

Furthermore, since the side bodies 3 and 4 can be formed to have any length, cases with various widths can be formed.

(g) Effect of the invention As explained above, this invention consists of a side body formed by cutting a long aluminum material extruded into a roughly shaped cross-sectional shape at an arbitrary length in the extrusion direction, and attaching the side body to both sides of the bottom plate. The opening front of the case body is formed by cutting a long extruded aluminum material with a roughly square cross section to an arbitrary length in the extrusion direction. Since the structure is such that the electronic device case is formed by disposing the case so as to cover the side surface of the opening, cases of various sizes can be manufactured by combining the case body, side body, and bottom plate, so mold costs can be reduced. Not only can it be made cheaper, but it can also be made at an extremely low cost and require less man-hours to manufacture for medium-scale production.It also simplifies inventory management, and since the case is formed by extrusion molding of aluminum. Creates a sturdy and elegant case,
If the bottom body is made of metal, it has practical effects such as increasing the electromagnetic shielding effect.
