Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to portable electronic devices such as radios and small receivers.

Structure of a conventional example and its problems In a conventional portable electronic device, a battery holder 2 is attached to a printed circuit board 1 as shown in FIG. This battery holder 2 has support plates 4 and 5 protruding from both ends of a side plate 3, and these support plates 4 and 5.
The terminals 6 and 7 supported by the terminals 6 and 7 are connected to the printed circuit board 1 by soldering or the like, and the printed circuit board 1 and the battery holder 2 are housed in, for example, a rectangular cylindrical case body 8 as shown in the figure. and a mounting bracket 9 fixed to the printed circuit board 1 are fixed with screws 10. Case body 8 has battery cover 1
1 is removably provided, and the battery 12 can be held in or removed from the battery holder 2 without removing the screws 10. Further, as shown in FIG. 2, another conventional portable electronic device uses a small battery 12a and stores components necessary for additional functions, such as a motor 13 for generating ringing vibration, in the remaining battery storage space. The battery holder 14 attached to the printed circuit board 1 has supporting plates 16 and 17 protruding from opposite ends of a side plate 15, and terminals 18 and 19 are supported on these supporting plates 16 and 17. Further, a side plate 20 is connected to the support plate 17 on the opposite side of the side plate 15, and a support plate 21 facing the support plate 17 is connected to the end of this side plate 20. Thus, the support plate 17, the side plate 20, and the support plate 21
A motor 13 is housed inside, and a fixing member 22 is interposed between the motor 13 and the printed circuit board 1. This battery holder 14 is attached to the large battery 12 mentioned above.
The configuration is completely different from that of the battery holder 14 that houses the battery. Therefore, if both are used in common, they must be managed as unfinished products not only during maintenance but also during the production process, making it impossible to hope for an improvement in productivity. Furthermore, if the battery holder 2 and 14 are to be managed as a finished product, the battery holders 2 and 14 must be reattached, which is extremely troublesome. Furthermore, one terminal 6
and 18 can be used in common regardless of the presence or absence of additional functions, but the other terminal 19 is complicated and the members themselves are economically disadvantageous.

Purpose of the invention With this invention, when additional functions are required, an auxiliary holder can be added without replacing the battery holder, and it can be managed as a finished product, improving productivity. It is an object of the present invention to provide a portable electronic device that is improved in that it does not require the work of reattaching the holder.

Structure of the Invention In order to achieve the above object, the present invention includes a battery holder that is housed in a case and has terminals facing each other, and a terminal that faces one terminal of the battery holder and can be connected to the other terminal. and an attachment means for attaching the auxiliary holder to the battery holder, so that when an additional function is required, the auxiliary holder only needs to be attached to the battery holder. It is something.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. As shown in FIGS. 3 to 5, a battery holder 32 is attached to a printed circuit board 31. This battery holder 32 has supporting plates 34 and 35 protruding from opposite ends of a side plate 33, and terminals 36 and 37 are supported by these supporting plates 34 and 35. The terminal 36 is formed by bending a plate spring material to give it spring properties, and the terminal 37 is formed into a flat plate shape, and these terminals 36 and 37 are connected to the printed circuit board 31. A female thread 40 is formed at the inwardly projecting end of the terminal 37 . For the terminal 36, a coil spring may be used instead of a plate spring as long as contact pressure can be ensured.

In the auxiliary holder 41, a frame body for storing additional parts is connected to one end of a mounting plate 42. That is, a support plate 43 is connected to one end of the mounting plate 42 in a perpendicular direction, a side plate 44 is connected to the opposite side of the side plate 42 on the support plate 43, and a support plate 44 is connected to the side plate 44 opposite to the support plate 43. 45 are installed in series.

This auxiliary holder 41 and the battery holder 32
is provided with attachment means for an auxiliary holder 41, which will be described later. As this attachment means, a non-circular engagement hole 38 such as a square shape is provided on the side plate 33 side of the terminal 37.
is formed, and a mounting hole 39 is formed in the middle part of the side plate 33, and this mounting hole 39 is formed as an internal thread or a simple hole. On the outside of the end of the support plate 45, a non-circular engagement protrusion 46 such as a square is provided so as to be inserted into the engagement hole 38. A hole 47 is formed. The middle part of the terminal 48 is attached to the outer surface of the side plate 44 with a screw 49, one side of the terminal 48 is bent to cover the support plate 43, and the other side of the terminal 48 is bent to cover the support plate 45.
It is bent to protrude to the side and has spring properties.

The printed circuit board 31, battery holder 32, etc. are housed in a rectangular cylindrical case body 50, and screw insertion holes 52 are formed in the bottom plate 51 of the case body 50.
By screwing the screw 53 into the female thread 40 of the terminal 37, it can be fixed in the stored state, and the terminal 37 also serves as a fixing metal fitting. By removing the battery cover 54, the battery 12 can be inserted between the terminals 36 and 37 and used as a power source.

Further, when using the motor (or auxiliary speaker) 13 for generating ringing vibration as an additional function, for example, the engagement protrusion 46 of the auxiliary holder 41 is inserted into the engagement hole 38 of the terminal 37 in the battery holder 32. the battery holder 32 from the mounting hole 47 of the rear side plate 42.
The auxiliary holder 41 can be fixed to the battery holder 32 by screwing the screw 55 into the mounting hole 39 of the side plate 33 in . In this state, the terminal 48 can be reliably brought into contact with the terminal 37 by utilizing its spring properties. By inserting the battery 12a between the terminals 36 and 48, it can be used as a power source. In addition, the motor 13 is inserted inside the support plate 43, the side plate 44, and the support plate 45,
By interposing the fixing member 56 between the printed circuit board 31 and the printed circuit board 31, the motor 13 can be fixed.

FIG. 6 shows another embodiment of the present invention. In this embodiment, a storage battery 12b is used, and screws 53 fixing the case body 50 and the terminal 37 are used.
is used as a charging terminal and brought into contact with one terminal 57 on the charger side. The other charging terminal 58 is soldered, for example, to the printed circuit board 31, a hole 59 is formed in the bottom plate 51 of the case 50, and a dustproof material such as rubber is installed between the terminal 58 and the bottom plate 51 on the outer periphery of the hole 59. The other charging terminal 61 on the charger side is inserted into the hole 59 and inside the cylinder 60 and brought into contact with the terminal 58 to charge the storage battery 12b. The configuration is the same as that of the previous embodiment.

Effects of the invention As is clear from the above explanation, according to the invention, additional functions can be provided by attaching an auxiliary holder to the battery holder, and there is no need to replace parts. It has the advantage that it can be managed as a finished product with the battery holder fixed, improving productivity and economic efficiency.
