BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case for accommodating a battery, and more particularly to a case for mounting a battery in an apparatus, wherein the battery can be accommodated in a lid.

[0002]

2. Description of the Related Art A conventional battery case, in which a battery is mounted on a device, and a battery can be stored in a lid,
It was a method of fitting to the device with claws in the front-back direction, or fitting one with claws and fixing the other with screws.

[0003]

In a battery case in which a battery can be housed in a conventional lid in which the device is fitted to the device with claws in the front-rear direction or one is fitted with claws and the other is fixed with screws. When the battery case is removed from the device and the battery is replaced, the battery case is pulled out more than necessary, the lead wires connected to the device are pulled out too far and the connection is separated, or the sharp end of the steel plate of the device is sharp. In the case of snap-type lead wires where the lead wire is cut off or the connection terminal is not fixed to the battery case, the case will be separated from the device when replacing the battery, so it will be lost or it will be attached to the device after replacing the battery Sometimes it caused the wrong direction.

[0004]

SUMMARY OF THE INVENTION In a device in which a battery case capable of storing a battery is mounted on a lid, a convex portion is provided on one side of the battery case via a flexible portion, and the size of the flexible portion is larger than the size of the convex portion. The other side is provided with fixing means to the device such as fitting with a nail, and a rising portion is provided on one side of the battery case hole of the device, and the rising portion has a convex portion of the battery case. A through-hole that can pass through is provided, and the rising portion is inclined to a predetermined position after inserting the convex portion into the through-hole and mounting the battery case.

[0005]

By raising the rising portion to a predetermined position, the size of the through-hole through which the projecting portion of the battery case can pass becomes smaller than the size of the projecting portion, and the case does not fall off from the device. Since the flexible portion is provided between the flexible portion and the convex portion, the battery case can be freely bent from the flexible portion, and the battery can be easily replaced without removing the battery case from the device body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1A is a diagram of a battery case according to an embodiment of the present invention, a mounting portion of a battery case of an apparatus, and a battery. The battery uses a snap-type electrode. FIG. 1B is a diagram in which the battery case is attached to the battery case hole of the device. The battery case (11), which is a resin molded product,
The battery is mounted on a member serving as a lid of the battery case hole (2) of the base of the device. The battery mounted on the battery case is not pressed off by the presser (15) so as to be detached.

On one side of the battery case, a thin portion (13) which is a flexible portion, and a protruding portion (12) which is a thick portion at its tip.
Is provided. The thin portion is for bending between the case body and the convex portion, and has a thickness of about 0.5 to 1 mm, and has a relief hole in the center for easy bending. The protruding portion (12) at the tip has a thickness (h) of about 3.5 mm and has a concave portion at the center to prevent shrinkage during resin molding.

On the other side of the battery case, there is provided a claw (14) for attaching / detaching the case to / from a device. Although not shown, a battery terminal (16) is provided in the case, and a lead wire (17) is connected thereto.

Guides (5) for stabilizing the case are provided on both sides of the battery case hole (2) provided on the base (1) of the device, and the base of the device is cut and raised on one side. There is a rise (6), a square hole (7) which is a through-hole at the center of the rise, and a cutout (3) on the other side for locking the nail (19) of the battery case. is there.
The square hole (7) is for the protrusion (12) of the battery case to pass through, and the height (H) is slightly larger than the thickness of the protrusion, about 3.5 mm, and about 4 mm, and the width is also the width of the protrusion. It is slightly larger.

FIG. 3 is a partial cross-sectional view of FIG. 1, wherein (A) shows a state in which the battery case (11) is mounted in the battery case hole (2) of the base (1), and (B) shows a startup ( 6) shows a state where the battery case is detached from the base for battery replacement. When the battery case is mounted on the device at the stage of assembling the device, the protrusion is passed through the square hole, and the claw (14) having the upper claw (18) and the lower claw (19) is engaged with the notch (3). After stopping (FIG. A), the rising (6) is inclined so that the height (H ′) of the square hole becomes smaller than the thickness (h) of the projection. (Figure B)

[0011] When the startup is inclined, as shown in Fig. C, even when the battery is replaced, the lower claw (19) is removed from the notch (3) and the battery case is removed from the device. The projection is locked at the start-up, and does not fall out of the device. Since the thin portion (13), which is a flexible portion, is provided, the case can be rotated to a position necessary for taking the battery in and out of the case, and the battery can be replaced smoothly without any obstacle.

2 and 4 are views of a conventional battery case.
After the front claw (10) of the battery case (9) is engaged with the front notch (4) of the base (1), the claw (14) is engaged with the notch (3). In the battery case of this conventional method, if the claw portion is removed from the base when replacing the battery, the case is mechanically connected to the device only with the lead wire, and a force acts to separate the lead wire, and ,
If the lead wire repeatedly comes into contact with a member around the battery case hole, it wears out and causes a failure.

FIG. 5 is a diagram illustrating a scale as an example of a device using the battery case of the present invention. FIG. 6 is a view of another embodiment of the present invention, in which the width of the flexible portion of the battery case is reduced.
0), the protruding portion is bent inward after inserting the protruding portion into the square hole (FIG. B), and is narrower than the width of the protruding portion to prevent the protruding portion.

[0014]

According to the above configuration, the case cannot be pulled out more than necessary, so that the lead wire can be prevented from being detached from the device. The lead wire is cut at the sharp end face of the steel plate of the device. And the battery case can be prevented from being lost.
