Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a housing for electronic equipment suitable for use as a cabinet for small electronic equipment.

Electronic devices such as radios and cassette tape recorders have become increasingly smaller in recent years, and as a result, how to simplify the structure of the cabinet, facilitate manufacturing, and reduce costs has become an important issue. I'm getting used to it. Particularly in the case of small electronic devices, since they use batteries, it is necessary to provide a battery cover to open and close the battery compartment. In many conventional cabinets, the battery cover is made separately and attached to the cabinet via a simple hinge. For this reason, a process for making the battery cover separately from the cabinet and the back cover of the cabinet is required, and there are also problems such as the battery cover being easily lost.

The present invention has been developed in view of the above-mentioned circumstances, and embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of a small radio to which the present invention is applied. A back cover 2 is detachably provided on the back side of the cabinet 1, and a speaker sound emitting net 3, a dial display section 4, and a tuning display section 5 are provided on the front side.
etc. are provided. Further, a dial operation knob 6, a volume knob 7, and a headphone insertion portion 8 are provided on the top surface.

Figure 2 shows the state in which the cabinet 1 and the back cover 2 are separated, and the cabinet 1 is connected to the speaker 9.
The figure shows the installed state, and the printed circuit board etc. are omitted. FIG. 3 shows the battery cover 10 in an open state, and FIG. 4 shows a side cross section of the radio. Second
In Figures 1 to 4, the cabinet 1 is, for example,
It is made by integrally molding hard synthetic resin such as HIPS, ABS, PBT, etc., and has one headphone insertion hole.
1, a volume knob insertion hole 12, a dial knob insertion hole 13, a dial display 14, a tuning display window 15, etc. are provided. Also, a boss 17 with a screw hole 16, a speaker holding piece 18, etc. are provided inside, and an engaging part 19 for attaching the back cover is provided on the side edge.
and a guide recess 20 are provided. The back cover 2 is formed by integrally molding a back cover body 21, a battery compartment 22, and a battery cover 10, and is made of relatively flexible synthetic resin such as polypropylene. The back cover body 21 has screw holes 2
3. The battery storage section 22, which is provided with a heat dissipation hole 24, a plurality of engagement protrusions 25, a guide protrusion 26, a hook recess 27, etc., is shown in a size that can accommodate, for example, two AAA batteries. It is formed in the shape of , and an electrode fitting 28 formed in the shape of a leaf spring is attached to the side surface thereof. Incidentally, an electrode fitting 29 is also attached to the cabinet 1 at a position opposite to the electrode fitting 28. As shown in FIG.
A hole 30 for locking the battery lid and a hole 31 into which a part of the voice coil portion 9a of the speaker 9 is inserted are provided on the boundary wall surface between the battery housing portion 22 and the battery housing portion 22. The battery lid 10 is rotatably provided integrally with the side edge of the battery storage portion 22 via a hinge portion 32 formed as a thin wall portion. The battery cover 10 is provided with an engaging protrusion 33, a hook protrusion 34, and the like. Incidentally, as shown in FIG. 4, a speaker suppressing rib 33 is provided on the lower surface of the battery storage section 22.
The restraining ribs 35 restrain the side edges of the speaker 9 to prevent the speaker 9 from floating up.

The back cover 2 is removably attached to the cabinet 1 by elastically engaging the engaging portion 19 and the protrusion 25. At this time, the guide protrusion 26 and the recess 2
0 are fitted. Further, as shown in FIG. 4, the battery cover 10 is locked in the closed state by elastically engaging the protrusion 33 in the hole 30. battery cover 10
When opening, it can be opened by inserting the tip of a toe into the recess 27 and hooking it onto the protrusion 34 and pulling it up. Further, a printed circuit board 37 with a circuit component 36 mounted thereon is housed in approximately two-thirds of the space within the cabinet 1, and a battery storage section 22 is housed in the remaining approximately one-third of the space. The back cover 2, the printed circuit board 37 and the cabinet 1 have screw holes 2 in the screws 38.
By inserting the printed circuit board 37 through the insertion hole 39 of the printed circuit board 37 and screwing it into the screw hole 16, the three components can be positioned and fixed in common.
Note that the back cover 2 may be provided with, for example, a rib for holding down the printed circuit board 37, if necessary, and the cabinet 1 may also be provided with a protrusion, etc., for supporting the printed circuit board 37, if necessary. .

According to the embodiment described above, since the battery compartment 22 and the battery cover 10 are integrally provided on the back cover 2, it is possible to omit the conventional step of making the battery cover separately from the back cover. . In addition, since synthetic resin such as polypropylene has flexibility, even if the hinge portion 32 is formed of a thin portion, it will not be broken due to fatigue during repeated opening and closing operations of the battery cover 10. Furthermore, even when screwing with the screws 38, since the back cover 2 has elasticity, this printed circuit board 37,
The three parts of the cabinet 1 can be fixed using only one screw 38. Also, polypropylene etc. are cheaper than HIPS, ABS, PBH etc. It should be noted that if flexible synthetic resin is used for the cabinet 1, the entire structure will easily deform, which is not preferable. For this reason, in this embodiment, the cabinet 1 is made of hard synthetic resin.

As described above, the present invention includes a battery compartment in the back cover 2, which constitutes at least a part of a housing such as a cabinet, and a battery lid 10 that closes the battery compartment.
A lid body like this is provided by integral molding, and at this time,
Since the lid body is integrally provided to the wall plate via a thin hinge portion so as to be openable and closable, the manufacturing process can be greatly simplified.
