DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery holding structure for holding a thin battery such as a button battery in a small electric appliance.

[0002]

2. Description of the Related Art In order to hold a button-shaped thin battery, the battery is generally inserted into a battery holder formed of a U-shaped or C-shaped molded product and inserted into the device together with the battery holder. In many cases, the paired terminals come into contact with both poles of the battery.

[0003]

In this case, in order to dispose a pair of terminals having a spring property on both sides of the battery on the device side, a thickness is absolutely necessary. The present invention has been made in view of such a point,
An object of the present invention is to provide a battery holding structure that can be reduced in thickness.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a flat U-shaped battery holder having a battery insertion portion formed therethrough.
And engaging both ends with both side pieces of the battery holder,
Battery bracket stretched between both sides and the battery holder
Is provided on one side of the board inside the equipment to be slidably mounted
And was held by the battery holder via the battery bracket
Terminals connected to one pole of the battery, provided on one surface of the substrate
Contacts the other pole of the battery held by the battery holder
A contact fitting, the battery fitting and the terminal, and a contact fitting.
With the above, electricity is supplied from the battery to the board side.
The battery bracket is located at the bottom of the battery holder in the battery holder.
The center of the battery is placed on the bottom of the battery to be inserted into the battery insertion part
Contact with one pole of the battery holder
From both ends engaged with both side pieces of
The protruding contact spring piece becomes the contact part with the terminal.
The feature is that it is.

In accordance with the present invention, on both poles of the battery even though in both sides, it is possible to energization at one side
In addition, the thickness of the battery holder can be reduced .

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment. The device 1 in the illustrated example is an electronic pedometer, and as shown in FIG. And a substrate 13 housed in the housings 11 and 12, and a liquid crystal display unit 1 mounted on the substrate 13.
4. It is composed of a transparent cover 15 and the like. In the figure, 46 is a push button, 47 is a hook button, and 48 is a hook spring.

[0007] Reference numeral 2 in FIG. 2 denotes a holder for attaching the device 1 to clothes. The holder 2 covers a display operation surface on one surface of the mounting body 1 and protrudes from the lid 20. Support piece 21, holding piece 2 further extended from support piece 21
2, and a pressing lever 30 rotatably attached to the support piece 21. The lid portion 20 has a hinge portion 23 rotatably attached to the mounting body 1 at one end edge thereof.
Is provided on the other end edge thereof with a hook 24 which engages with the hook button 47. The support piece 21 is provided so as to be folded back from the other end side, and has a predetermined gap between the support piece 21 and the back surface of the lid portion 20. Is kept. The holding piece 22 is provided so as to protrude from the tip of the support piece 21 so as to be further folded back, and is formed as having a spring property, and is closer to the lid 20 than the support piece 21.

The pressing lever 30 is formed by supporting a shaft 33 inserted through a shaft hole 31 provided at one end of the pressing lever 30 by a bearing portion 25 formed in the middle of the supporting piece 21. The holding piece 22 is pressed against the lid 20 by this rotation, and the clothes are sandwiched between the holding piece 22 and the lid 20. .

The button type battery 40 is mounted in the device 1 while being mounted on the battery holder 41. The battery holder 41 is, as shown in FIGS. 7 and 8,
A portion into which the battery 40 can be fitted is formed through .
It has a flat U-shape, and a battery fitting 42 is attached to the lower surface side of the battery fitting portion . This battery bracket 4
Numeral 2 is stretched between both sides of the battery holder 41. The battery is located at the bottom of the battery insertion portion at the center.
The battery 40 has a convex portion 42a in contact with the cathode side of the battery 40 loaded in the pond fitting portion, and a pair of contact spring pieces 42b, 42b protruding upward at both ends.

On the other hand, a substrate 13 arranged in the device 1 has
A contact fitting 16 that comes into contact with the anode of the battery 40 is attached. As shown in FIG. 9, the contact fitting 16 uses a groove 18 formed in the
Is attached to the substrate 13 so as to substantially fit within the thickness of the substrate 13. And it is slidable to the device 1
The battery 40 is attached to the battery holder 41 which is
When the battery holder 41 is slid and stored in the device 1 in this state, the contact spring 16a of the contact fitting 16 contacts the anode of the battery 40 as shown in FIG.
The battery fitting 42 attached to the battery 1 and having its convex portion 42a in contact with the cathode of the battery 40 protrudes toward the substrate 13.
The contacting spring pieces 42b, 42b are brought into contact with terminals (not shown) formed on the substrate 13.

As described above, in the present invention, the poles are on both sides.
Used batteries in spite of, which can be achieved energization at one side, yet slidably equipment
The battery holder to be stored in the
Therefore, the thickness of the device can be reduced.
