Abstract

PURPOSE:To simply accommodate batteries and surely prevent coming off of the accommodated batteries. CONSTITUTION:A battery 17 is accommodated in a compartment 16 in such a way that its anode 14 is pressed against a coil spring 45 of an electrode 20, then its cathode 48 is pressed against a bottom plate 22 so as to get over a coming-off prevention plate 41. Since the battery 17 is pressed against an electrode 21 by elasticity of the coil spring 45, the cathode 48 is surely brought into contact with a projecting part 36. Since the coming-off prevention plate 41 prevents coming off of the battery, batteries 17 are accommodated in order in the compartment 16. Since the coming-off prevention plate 41 is extended from the projecting part 36 toward the compartment 16, contact of the anode 49 to the projecting part 36 is prevented even if the battery 17 is accommodated with its polarity opposite.

0, and a conductive conical coil spring 45 is connected to the locking hole 32 and the locking piece 33. Note that a plate-shaped spring may be used instead of a coil spring.

Next, a procedure for assembling the above structure will be explained. First, hold the connecting piece 31 of the conductive plate 30 with your fingertips, and insert the edges 30a, 30a into the pair of insertion grooves 37. as shown in FIG.
Insert into 37. Once the upper portion of the edge 30a shown in FIG. It fits easily and allows the above-mentioned insertion to be performed easily. Then, once the electrode 21
When the conductive plate 3o is fixed to the wall 18 (or 19), the conductive plate 3o is fixed to the opposing wall 18 (or 19) and cannot be easily moved.

Next, the work of installing batteries into the battery storage box 6 will be explained. First, hold the battery 17 and insert the anode 4 while pressing the cathode 49 side against the coil spring 45 of the electrode 2o as shown by the solid line in FIG.
8 to the bottom plate 22 side. Then, the anode 48 of the battery 17 is removed from the removal prevention plate 4 as shown by the two-dot chain line at the top of FIG.
Overcome 1. After this, the battery 17 is pressed toward the electrode 2 by the elastic force of the coiled spring 45, so that the anode 48 of the battery 17 reliably contacts the bulge 36. Even if the battery 17 installed in this way is turned upside down as shown in the lower part of FIG. 6, the connection between the electrodes of the stain pond 17 and each electrode 20.21 is maintained by the elastic force of the coiled spring 45. be. Further, even if vibration is applied, the battery anode 48 is caught on the retaining plate 41, and the stain pond 17 is prevented from falling off. Since the removal prevention plate 41 prevents the battery from coming off in this way, the battery storage box 6
Even if the two box bodies 15 are connected back to back, the batteries 17 can be installed one after another into the battery storage space 16.

Since the retaining plate 41 still protrudes toward the storage space 16 as well as the bulge 36 , even if the battery 17 is installed with the cathode and anode reversed, the cathode 49 of the battery 17 will be attached to the bulge 36 .
Needless to say, contact with the device is prevented, and incorrect connection often damages the electronic circuit of the device.

When removing the battery installed in the above manner for replacement, etc., gently press the anode 48 side of the battery 17 with your thumb or the like against the electrode 20 for the cathode 49, and then By pulling it out, the battery can be easily removed.

It should be noted that the above-described installation and removal work of the battery 17 can be performed with the battery storage box 6 pulled out from the electronic device main body 1 as shown in FIG. 1, so that the work efficiency is good.

Furthermore, even if shock or vibration is applied to the electronic device with the battery storage box 6 stored inside the electronic device 1 as shown in FIG.
The battery 17 will not fall off from the battery storage box 6.

As described above, in this application, since a retaining plate is used on the anode side of the battery storage box and a coiled spring is used on the cathode side, the battery can be easily installed in the battery storage box, and the battery can be easily installed. This has the effect of making it possible to securely install the battery without worrying about it falling off.
