As shown in FIGS. 3 and 4, support pieces 18A and 18B for supporting the ends of the long sides of the printed circuit board 4 to be accommodated are provided at substantially the center of the inside of the longitudinal side wall of the casing main body 6, as shown in FIGS. Have been. The printed circuit boards 4 to be accommodated are respectively provided inside the short side walls connected to the longitudinal side walls of the casing main body 6.
A pair of support bases 1 each receiving the short side ends of the base from below.
6RA and 16RB, supports 16LA and 16LB
Is provided.

At the bottom of the casing body 6, there are provided connecting bearing stands 20L and 20R corresponding to the cutouts 4a and 4b of the printed circuit board 4 and connected to the connecting shaft 12 of the cover member 2, respectively. Connecting bearing stand 20L and 2
0R have the same structure as each other,
L will be described, and redundant description of the connection bearing stand 20R will be omitted.

The connecting bearing stand 20L is indicated by an arrow B in FIG.
5, that is, when viewed from the bottom, a through hole 26b into which the tapping screw 22L is inserted substantially in the center as shown in FIG. As shown in FIG. 4, a proximal end 26B that forms a connecting portion of the bearing stand 20L and a step 26A that is continuous with the proximal end 24B and bends to form a part of the same plane as the bottom of the casing body 6. And a dividing portion 26 consisting of The base end portion 26B of the dividing portion 26 is connected to a connection portion of a connection bearing base 20L protruding inside the casing body 6 via the thin portions 26C and 26D. The length of the base portions 26B of the thin portions 26C and 26D along the circumferential direction is, for example, about 3 mm.

A penetrating opening 24B is formed between the outer peripheral portion of the base end portion 26B and the connecting bearing stand 20 so as to have a uniform width, for example, about 1 mm along the outer peripheral portion of the base end portion 26B. .

As shown in FIG. 6, each of the thin portions 26C and 26D has a groove 28 having a predetermined depth, for example, about 2 mm, formed on the outer surface thereof.

An opening 24A having a width of about 1 mm or more is formed along the outer periphery of the step 26A between the outer periphery of the step 26A and the bottom of the casing body 6.

Therefore, the dividing portion 26 is connected to the casing main body 6 only through the thin portions 26C and 26D. In addition, according to an experiment by the present inventor, the load applied in a normal use state is changed to the thin portion 2.
6C and 26D, the dividing portion 26 is formed by the thin portions 26C and 26D of the casing body 6.
It has been verified that there is no disconnection from

The cover member 2 is, for example, injection molded of a thermoplastic resin with an average thickness of about 3 mm, similarly to the casing body 6. On the flat surface inside the cover member 2, two connecting shafts 12 corresponding to the cutouts 4 a and 4 b of the printed circuit board 4 and extending perpendicular to the flat surface are formed integrally with the cover member 2. As shown in FIGS. 3 and 4, for example, a bottomed hole 12t into which metal tapping screws 22L and 22R are screwed is provided inside the distal end portion of each connection shaft 12, respectively.

As shown in FIGS. 3 and 4, the printed circuit board 4 in the casing body 6 is provided around the outer periphery of each connecting shaft 12 with supporting pieces 18A and 18B, supporting stands 16RA and 16RB, Supports 16LA and 16L
B and thin plate-shaped ribs 12A and 12B to be held in cooperation with B
Are formed integrally with the connection shaft 12. A thin portion 14 having a groove inside is formed around a portion of each connecting shaft 12 connected to the cover member 2. Thin part 14
Is set to, for example, about 1.5 mm.
In addition, according to an experiment by the present inventor, even when a load applied in a normal use state is applied to the thin portion 14, the connecting shaft 12 is not separated from the thin portion 14 of the cover member 2. Has been verified.

Therefore, the cover member 2 is connected to the connecting shaft 12
After being arranged with respect to the open end of the casing body 6 in which the printed circuit board 4 aligned and aligned with
The tapping screws 22 </ b> L and 22 </ b> R are inserted through the through holes 26 b and screwed into the holes 12 t of the connection shaft 12, whereby the tapping screws 22 </ b> L and 22 </ b> R are coupled to the casing body 6. That is, the electronic component storage portion is formed inside the cover member 2 and the casing main body 6.

The power supply unit 3 assembled as described above
6 is a case where the end of the tool Tu such as a screwdriver is inserted into the opening 24A as shown by a two-dot chain line in FIG. By pressing the outer side 26, the dividing section 26
Are thinner portions 26C and 26D as shown in FIG.
Thus, the casing is separated from the casing body 6. Therefore, the cover member 2 is easily removed from the casing main body 6 together with the printed circuit board 4 with the dividing portion 42 connected to the connection shaft 12. At that time, openings 40 are respectively formed in the portions of the bottom of the casing body 6 where the dividing portions 26 were provided.

Subsequently, the cover member 2 is
Are removed from the connecting shaft 12, the respective connecting shafts 12
Is relatively easily divided by the thin portion 14 with the dividing portion 42. Therefore, a waste member 46 having the dividing portion 42 and the tapping screws 22L and 22R is obtained. Further, a cover member 2 ′ having a hole 44 formed by dividing each connecting shaft 12, and a dividing portion 2.
As a result, the casing main body 6 'in which the casing 6 is divided is obtained.

Therefore, when the power supply unit 36 is disposed of, the cover member 2 and the casing body 6 are relatively easily disassembled, and the printed circuit board 4 and the tapping screws 22L and 22R are easily disassembled. And will be decomposed.

The tapping screws 22L and 22R
When the material is the same as the material of the cover member 2 and the casing main body 6, such a separation is not necessary, so that the operation of separating the connection shafts 12 as described above is not required.

[0027]

As is apparent from the above description, according to the housing for electronic equipment according to the present invention, the thin portion which can be separated from the first housing and the second housing has A portion to which one end of the connection portion in the first housing is connected, and
Since the other end of the connecting portion in the second housing is formed around the portion to be connected, its outer portion is not easily disassembled in a normal use state. , Each component can be easily separated and disassembled.
