Description

[Detailed Description of the Invention] The present invention relates to a battery holder for storing a battery, such as a 3V class lithium battery, used in a microcomputer or the like to retain memory contents during a power outage.

Although lithium batteries have been mass-produced in earnest over the past few years and are entering the practical stage, there is currently no dedicated holder for lithium batteries. In addition, lithium batteries cannot be used with commercially available battery holders because their external dimensions are slightly different from those of other dry batteries.

In addition, conventional battery holders are attached to the surface of the device panel because the user performs battery replacement and maintenance, but there are many functional problems caused by batteries falling out of the holder or being exposed on the surface. It was done.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a battery holder that overcomes the drawbacks of conventional devices.

FIG. 1 is a perspective view of one embodiment of the present invention, and FIG. 2 is a front view as viewed from arrow A in FIG.

1 is the battery holder body, 3 is the lithium battery, 4
is a lead wire from the battery electrode, 11 is a flange provided on the side tip surface of the battery holder, 12 is a mounting hole for mounting a board drilled at the bottom of the battery holder that houses the battery, 13 is a battery holding surface, and 14 is a A space for dodging the battery electrodes and lead wires, 15 is a groove for an insulator lock.

FIG. 3 is a perspective view of the present invention mounted on an external panel of a device.

Reference numeral 2 denotes a panel, which is mounted using small mounting screws 5 inserted into mounting holes (round holes) 16 in the flange portion 11 of the panel 2.

Since the battery 3 is held between the panel 2 and the bottom and both side surfaces of the battery holder 1, there is absolutely no chance of the battery 3 falling off.

In addition, maintenance such as battery replacement can be carried out freely by attaching and detaching the mounting screws 5, which is very convenient.

FIG. 4 is a perspective view of the present invention installed on a board inside a device.

In this case, the battery holder 1 is screwed onto the board 7 by means of a countersunk mounting screw 6 inserted into a mounting hole 12 for mounting onto the board 7 formed in the bottom of the battery holder 1 .

If necessary, for example, when a strong impact is expected during transportation, the insulator lock 8 is installed in the insulator lock groove to insulate the battery 3.

Thus, according to the present invention, the battery never falls off, and it is convenient for both the external panel of the device and the internal board of the device by simply changing the mounting location using the same shape, making it suitable for mass production and low cost. can.
