Abstract

PURPOSE:To provide a battery holder wherein a battery can not be easily inserted in the case of inserting it in a wrong direction of polarity. CONSTITUTION:A battery holder, having in its upper surface a spring which has further action of pressing a battery downward, has a partly lacked angular part in the bottom surface, and the battery, when inserted reversely, is pressed downward by the spring in the upper surface, so that the battery can not be inserted by hitting an angular part 21 in the holder bottom surface by a protruding terminal 17a of the battery to prevent advancing on and after the angular part.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery holder for a disk-shaped battery such as a lithium battery.

[0002]

2. Description of the Related Art Conventionally, a battery holder of this type is, for example,
As described in Japanese Examined Patent Publication No. 3-40464, use the corners of the spring body, the case of the battery, and the step formed by the sealing plate to prevent the entry even when the battery is mistakenly inserted in the opposite direction. The following are proposed and used.

[0003]

In the conventional structure described above, when the corners of the spring body are caught on the step between the battery case and the sealing plate to prevent entry, the strength of the spring body is weak,
If you try to insert it forcibly, you risk slipping.

The present invention is intended to solve these problems, and provides a battery holder which can be reliably prevented even if it is inserted incorrectly by mistake.

[0005]

In order to solve these problems, the present invention provides a holder main body in which a plate portion and a frame portion are integrated with each other, a first terminal for contacting a disk-shaped battery and a first terminal. Two
And a plate portion provided so as to correspond to one surface of the battery, and at least a part of the frame portion is integrally formed with the plate portion, and most of the frame portion is integrated with the frame portion. It is made up of two types, a non-integrated part and a part that is mostly integrated with the plate part.The frame part that is not mostly integrated with the plate part can be surrounded from both sides of the battery. It bends and forms an elastic force in the direction of the battery main body when the battery is stored, and most of it presses the battery stored in the frame part that is integrated with the plate part, and the first terminal is the plate part. The battery is pressed against the plate part by contacting one surface of the battery which is in contact with the one side of the battery, the second terminal is arranged on the plate part, the one surface of the battery is pressed, and the battery of the holder main body is pressed and clamped from above and below. The first terminal and the second terminal are provided, and the plate portion is further provided with a partially cutaway portion. It constitutes a corner portion with respect to the battery insertion direction.

[0006]

By using the holder of the present invention, the battery can be stably stored in the holder, the battery can be easily attached and detached, and even if the battery is mistakenly inserted in the opposite direction, the battery is not stored. It is safe, convenient and informative.

Embodiments of the present invention will be described below with reference to FIGS.

FIG. 1 is a plan view showing an embodiment of a battery holder according to the present invention, and FIG. 2 is a central sectional view of FIG.

Reference numeral 1 denotes a plate portion of the holder main body 20, which is integrated with the curved frame portions 4 and 5 through the integral portions 2 and 3 and also with the fixed frame portions 6 and 7. The curved frame portions 4 and 5 are curved inside the holder main body, and there is a gap 8 between the curved frame portions 4 and 5, and the curved frame portions 4 and 5 extend from the integrated portions 2 and 3 to the curved frame portion tip portions 9 and 10. The structure has spring elasticity. Further, since the curved frames 4 and 5 surround the battery, in order to prevent the mounted battery from falling off the holder body,
The fixed frame portion 6 is provided in a direction facing the curved frame portions 4 and 5, respectively.
7 is provided. Most of the fixed frame portions 6 and 7 are integrated with the plate portion 1, and edge portions 11 and 12 are formed at the tips of the fixed frame portions 6 and 7 to prevent the mounted battery from popping out. . The battery is fixed by being pressed into contact with the fixed frame portion by the elastic force of the curved frame portion. That is, the diameter of the inscribed circle formed by the curved frame portions 4 and 5 and the fixed frame portions 6 and 7 must be equal to or less than the diameter of the battery when the battery is not mounted.

At the position facing the fixed frame parts 6 and 7,
A first terminal 13 of a conductive material that collects current from the pole is attached, and is integrated with a terminal 14 that presses the + pole of the battery and sends electricity to the mounting board. Also, the battery
The second terminal 15 made of a conductive material having electrical contact with the pole is the plate portion 1
Is disposed on the inner surface of the terminal and is integrated with the terminal 16 that sends electricity from the battery holder to the mounting board. Then, the first terminal 13 and the second terminal 15 press and sandwich the battery from above and below.

Further, below the main body projecting portion 19, a partially cutout portion 22 is provided in the central portion of the plate portion 1, and the cutout portion 22 forms a corner portion 21 at a portion of the plate portion 1.

With this structure, the battery 17 can be easily inserted through the opening 18, is pressed against the fixed frame portions 6 and 7 by the elastic force of the curved frame portions 4 and 5, and pops out by the edge portions 11 and 12 of the fixed frame portions. And the second terminal 1 installed on the plate 1 is prevented.
5 and the first terminal 13 are pressed and sandwiched from above and below, but as shown in FIG. 3, when the inserting direction of the battery is reversed, the protruding terminal portion 17a of the battery 17 is removed from the plate portion 1. Part 22
The battery 17 cannot be inserted because it is caught in the corner portion 21 formed by the above and the battery 17 does not advance further than the corner portion 21. Further, as shown in FIG. 4, when the battery 17 is inserted in the correct direction, the curved surface of the battery end slides at the corner 21 and slides in the direction of the arrow for proper insertion.

FIG. 5 shows a conventional example. It is stopped at a step formed by the battery case and the sealing plate, and if it is deliberately passed down or pushed in with a large force, there is a problem that it will enter in the opposite direction. Occurs.

[0014]

As described above, according to the battery holder of the present invention, even if the battery holder is mistakenly inserted in the opposite direction, it cannot be completely inserted.
It is possible to provide a battery holder that can prevent damage to the device due to incorrect polarity of the battery.
