Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery housing device, and more particularly to a battery housing device in which a pair of batteries are arranged side by side in a battery housing portion.

[0002]

2. Description of the Related Art For example, in a drive unit of a hearing aid,
As shown in FIG. 14, a battery housing 1 is provided, and two cylindrical batteries 2 are arranged side by side in the battery housing 1 so as to face in opposite directions. The negative electrode is adapted to be crimped to the terminal spring 3. Then, in this way, the two batteries 2 are placed in the battery compartment 1.
The battery lid can be attached so as to close the upper opening in a state where they are stored side by side.

[0003]

When the battery 2 in the battery housing 1 is discharged, it must be replaced or taken out and charged. Therefore, conventionally, as shown in FIG. 15, by pressing the positive electrode portion of one battery 2 with a finger, the terminal spring 3 in contact with the negative electrode
Then, a gap is formed between the positive electrode of the battery 2 and the terminal plate on the positive side of the battery 2, and the battery 2 is taken out by prying this portion with a finger. According to such conventional removal of the battery 2, not only the force is required to remove the battery 2, but also the fingertip may be hurt.

In order to prevent such a problem, the ribbon 4 is attached in advance in the battery housing 1 and the ribbon 4 is pulled when the battery 2 is taken out. However, when the ribbon 4 is pulled out and the battery 2 is taken out, there is a problem that the terminals such as the terminal springs 3 that come into contact with the electrodes of the battery 2 are easily damaged. Further, in some cases, there is a problem that the ribbon 4 cannot be used after being cut.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a battery accommodating device capable of easily taking out a battery.

A locking claw 38 is continuously provided on the side end of the battery lid 21.

Two batteries 20 are accommodated side by side in such a battery accommodating portion 18 with their electrodes oriented in opposite directions. The positive terminals 26, 2
It is also possible to store the electrodes of the two batteries in the same direction by changing the arrangement of the 9 and the minus side terminals 27, 28.

When the two batteries 20 are stored in the battery storage portion 18, the sliding plate 25 is moved leftward to the maximum retracted position as shown in FIG. Form a space. Therefore, when the battery 20 is attached, the terminals 26 to 29 do not get in the way, and the battery 20 is easily stored in a juxtaposed state.

After that, the battery lid 21 is mounted. At this time, the pressing projection 36 provided on the lower surface of the battery lid 21 presses the rear side inclined surface 35 of the sliding plate 25,
As a result, the sliding plate 25 is moved to the right as shown in FIG. 6, and the terminals 26 and 27 attached to the sliding plate 25 are pressed against the corresponding electrodes of the battery 20. Therefore, it becomes possible to extract the output from the two batteries through the terminals 26 to 29, which drives the drive unit 10 of the hearing aid.

When the battery 20 is discharged, the battery lid 21
Remove. After this, as shown in FIG. 5, the sliding plate 2
Move 5 to the left. As a result, the electrodes 26 and 27 of the sliding plate 25 are separated from the corresponding electrodes of the battery 20. Therefore, the force for tightening the battery 20 in the longitudinal direction is eliminated, and the battery 20 can be easily removed. Moreover, since an unreasonable force is not applied to the terminals 26 to 29 at this time, the terminals 26 to 29 are not damaged and their durability is improved.

Next, another embodiment will be described with reference to FIGS. In this embodiment, a rotatable terminal plate 42 is used instead of the sliding plate 25. Terminal board 4
The pin 2 is provided with pins 43 on both sides of its lower end so as to project laterally, and is rotatably supported by the pins 43 on the side end bottom of the battery housing 18.

The terminal plate 42 has a battery 20 at the lower end thereof.
The receiving portion 44 is provided so as to project in the length direction of the battery 20, and the receiving portion 44 receives the end portions of the batteries 20 housed side by side in the battery housing portion 18. Further, a pair of circular openings 45 is formed in the terminal plate 42, and the positive side electrode 26,
29 is attached to the terminal board 42. An operating projection 46 is continuously provided on the upper end side of the terminal plate 42.

When the batteries 20 are mounted in the battery housing 18 having such a terminal plate 42, the positive electrodes of the two batteries 20 are received by the pair of openings 45 of the terminal plates 42, respectively. Installing. Then, the lower portions of the positive electrodes of the two batteries 20 are received by the receiving portions 44 of the terminal plate 42, and the terminal plate 42 is rotated about the pins 43 as shown in FIG. Become. At this time, the negative electrode of the battery 20 is crimped to the corresponding negative terminal 30.

In such a state, when the battery lid 21 is mounted as shown in FIG. 9 so as to close the upper opening of the battery housing portion 18, the pressing projection 36 provided on the lower surface of the battery lid 21 is attached. The inclined surface 37 presses the tip of the operating projection 46 of the terminal plate 42, thereby preventing the terminal plate 42 from rotating counterclockwise about the pin 43 in FIG. become. That is, the terminal board 42
The receiving portion 44 prevents the lower portion of the positive electrode of the battery 20 from rotating in the upward direction.

Next, when the battery 20 is discharged, the battery lid 21 covering the upper opening of the battery housing 18 is removed, and then the operating projection 46 of the terminal board 42 is moved downward as shown in FIG. By pressing, the terminal plate 42 is rotated counterclockwise about the pin 43. Then, the receiving portion 44 of the terminal plate 42 pushes up the lower part of the positive side electrodes of the pair of batteries 20, whereby the battery 20 is lifted diagonally. At this time, the spring 28 constituting the negative terminal urges the battery 20 to escape. Therefore, it becomes possible to easily take out the battery 20 from the battery housing portion 18 by grasping the portion of the battery 20 especially near the positive electrode.

Next, still another embodiment will be described with reference to FIGS.
3 will be described. In this embodiment, a rotatable terminal plate 42 is provided, and the lock pin 50 is held so that the terminal plate 42 is held at the battery mounting position.
Is provided. The lock pin 50 includes a flange 51, and a portion of the flange 51 is pressed by a spring 52. An operation button 53 is provided at the end of the lock pin 50 to return the spring 52 in the opposite direction to the moving direction by the pressing force of the spring 52.

Therefore, a pair of batteries 20 are provided in the battery housing portion 18.
And the positive electrodes of these batteries 20 are inserted into the openings 45 of the terminal board 42, respectively.
By bringing the battery 20 into contact with the battery compartment 18,
Attached to. In such a state, the lock pin 50
When the back side portion of the terminal plate 42 is pressed as shown in FIGS. 11 and 12, the terminal plate 42 is rotated counterclockwise in FIG. 12 about the pin 43 by the spring composed of the minus side terminal 28. Is blocked. Therefore, the battery 20 in the battery housing portion 18 keeps a properly mounted state.

When the battery 20 is discharged, the operation button 53
The lock pin 50 is moved upward in FIG. Then, the lock of the terminal plate 42 by the lock pin 50 is released. Therefore, when the operating projection 46 is pushed in such a state, the terminal plate 42 is rotated counterclockwise around the pin 43 as shown in FIG. 13, and the receiving portion 44 thereof receives the positive electrode of the battery 20. The lower part will be pressed. At this time, the spring 28 causes the terminal plate 4 to
It acts to assist the rotation of 2. Therefore, the battery 20 can be pushed up diagonally and can be easily taken out.

Although all of the above-mentioned three embodiments relate to the battery storage device of the drive unit 10 of the hearing aid, the present invention stores the batteries of various other electronic devices such as headphone stereos and radios. Widely applicable to the department.
