Description

[Detailed description of the invention] The present invention relates to a battery storage device for electronic equipment.
The purpose is to provide an excellent battery storage device that can be installed reliably with a simple structure, without having to use separate cabinets and battery covers, regardless of whether primary or secondary batteries are used. There is a particular thing.

In general, in battery storage devices for electronic devices, the structure of the cabinet and its battery cover is equipped with a recess for storing batteries, depending on whether primary batteries such as manganese batteries are used or secondary batteries such as nickel-cadmium batteries are used. were different.

In other words, when primary batteries are used, the batteries must be replaced frequently, so the battery cover needs to be configured to be easy to remove from the cabinet and easy to install so that battery replacement can be done easily. When using batteries, it was necessary to secure the battery cover to the cabinet using screws or other methods to prevent batteries from exploding due to incorrect use, making it difficult to replace the batteries.

Therefore, in order to support the two purposes of use as mentioned above, it is necessary to design a cabinet and battery cover suitable for each function and use them depending on the battery used, resulting in an increase in the number of parts. However, the cost of the mold also increased, causing an increase in costs.

The present invention eliminates these conventional drawbacks,
Hereinafter, the present invention will be explained with reference to drawings of embodiments.

In the figure, 1 is a cabinet lid case, 2 is a cabinet body case, and a screw 4 inserted into a screw fixing hole 1-a provided in the cabinet lid case 1 is connected to a boss 2-a which is protruded from the inner surface of the cabinet body case 2. A is integrated by tightening it to form a cabinet for electronic equipment.

A battery storage recess 8 is formed in the cabinet, and the opening thereof is connected to the cabinet lid case 1.
formed on the side.

3 is a battery cover for closing the opening of the battery storage recess 8 provided in the cabinet, and has screws 3-C and 3-c that fit on both opposing sides, and the center of the end surface An elastic tongue piece 3-d having engaging protrusions 3-h and 3-1 at its tips, and a screw fixing rib 3-e having a screw fixing hole 3-f at its tip, which is offset to the right from the center, are protrudingly provided. ing.

The battery cover 3 is provided with a finger groove 3-g on the surface near the elastic tongue 3-d.

Here, the battery lid 3 has the fitting ribs 3-C, 3-c so that the finger hook groove 3-g faces the front side when the primary battery 5 is placed in the battery storage recess 8. is a guide 1l-ct provided on the side of the opening of the cabinet lid case 1.
1-c.

Therefore, the surface 3-a of the battery lid 3 provided with the finger-rest groove 3-g is used as the front side.

On the other hand, the battery lid 3 has the fitting ribs 3-c and 3-c as guides so that the finger hook recess 13-g faces inward when the secondary battery 6 is installed in the battery housing recess 8. Groove 1-C
91-c.

Therefore, the surface 3-b of the battery lid 3 on which the finger-rest groove 3-g is not provided is used as the front side.

A charging terminal insertion groove 1-d is provided on the side surface of the cabinet lid case 1, into which a charging terminal 7 can be inserted as appropriate.

Further, the inner surface of the cabinet lid case 1 has an engaging groove 1- into which the retaining protrusions 3h and 31 of the battery lid 3 are engaged.
b is provided.

In such a configuration, when the cabinet 1.2 and the battery cover 3 are used with the primary battery 5 installed in the battery storage recess 8, the battery is inserted as shown in FIGS. 1 and 2. Fitting ribs 3-c provided on both sides of the lid 3
, 3-c into the guide grooves 1-C, 1-c, and the engaging protrusion 3-h at the tip of the elastic tongue piece 3-d provided at the center of the tip surface of the battery cover 3 into the engaging groove 1. - engage b.

By using the battery cover 3 in this manner, the battery cover 3 can be made detachable using its finger hook recess 13-g, and is suitable for a battery storage device when using batteries that are frequently replaced. do.

At this time, the screw fixing rib 3-e having the screw fixing hole 3-f provided on the front end surface of the battery cover 3 is connected to the elastic tongue piece 3-e.
It is located at a symmetrical position to the screw fixing hole 1-a provided in the cabinet lid case 1 with reference to point d as the center, and is not used for screw fixing.

In addition, the charging terminal 7 is basically not attached to the charging terminal insertion 11-d provided on the side surface of the cabinet lid case 1, but even if the charging terminal is attached, it may be attached to both poles of the storage recess. Do not make electrical connections to battery terminals.

On the other hand, when the cabinets 1, 2 and the battery lid 3 are used to mount the secondary battery 6 in the battery storage groove 8, both sides of the battery lid 3 are inserted as shown in FIGS. 4 and 5. The engaging ribs 3-c and 3-c provided on the surface are connected to the guide groove 1.
-c, 1-C, and engage the retaining protrusion 3-i at the tip of the elastic tongue piece 3-d provided at the center of the front end surface of the battery lid 3 with the engaging groove 1-b, and screw the screw. The screw hole 3-f at the tip of the stopper rib 3-e corresponds to the screw hole 1-a of the cabinet lid case 1.

Then, by inserting the screw 4 into the screw fixing hole 1-a and tightening it onto the boss 2-a, the screw fixing rib 3-e is tightened together, and the battery cover 3 is attached to the opening of the battery storage recess 8. It is firmly fixed to the above cabinet so as to cover the area.

At this time, since the finger-rest groove 3-g of the battery cover 3 faces inward, it is no longer visible and does not give an instruction to open the battery cover 3, which is convenient.
-d is electrically connected to the battery terminal.

As described above, according to the present invention, it is possible to provide a battery storage device suitable for two purposes using the same cabinet and battery cover, and the battery cover can be attached securely. It is something that can be done.

In addition, when tightening the screw fixing rib 3-e together with the screw 4, the cabinet body case 2 and the cabinet lid case 1
If the ribs 2-a and 3-e are loose, a step is provided at the tip of the boss 2-a, and a notch is provided at the tip of the screw fixing rib 3-e, and the rib 3 is tightened with the notch inserted into the step. -e
may be held between the cabinet lid case 1 and the boss 3-a.
