Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery electrode structure, and more particularly to a battery electrode structure, such as a portable information terminal, in which a battery is firmly held so as not to cause instantaneous interruption or poor contact of the battery. It relates to an electrode structure.

[0002]

2. Description of the Related Art Conventionally, in a device such as a portable information terminal or the like, a means for improving battery take-out is provided with an escape portion for inserting a finger between a fixed electrode and a battery. There is a method of using a belt-shaped ribbon to which is fixed, pulling the other end of the ribbon, and taking out the battery.

As a related prior publication, Japanese Patent Laid-Open Publication No.
There is 129999 publication. The contents are as follows.A movable terminal is provided on the axial case of the battery to be mounted via a spring, and the movable terminal which is not normally in contact with the battery electrode is pressed by a pressing arm attached to the battery cover by a reaction force of the spring, and the spring is pressed against the spring. It is moved in the axial direction in opposition to obtain contact with the electrodes.

[0004]

A first problem is that the provision of a finger escape portion does not fundamentally improve battery take-out.

[0005] The reason is that it is difficult to apply force because the battery needs to be taken with a fingertip.

A second problem is that when a ribbon is used, the ribbon may be pinched when the battery cover is attached.
There is a problem that the ribbon may be completely hidden in the battery housing when the battery is mounted, and the function may not be performed.

The reason is that the ribbon has a structure in which only one end thereof is fixed to the battery housing portion side.

[0008] The third problem is disclosed in Japanese Patent Application Laid-Open No. 8-129999.
Also in the publication, the removal of the battery involves difficulty as described above.

The reason is that, when the battery cover is removed, the contact between the movable terminal and the electrode is automatically released by the reaction force of the spring, but the battery itself remains in the case. Because.

It is an object of the present invention to provide a battery removal electrode structure which uses an electrode structure movable in a direction perpendicular to the battery axis and which can easily remove a battery simply by pressing a component, thereby improving operability. .

[0011]

According to the present invention, there is provided a battery detaching electrode structure comprising a negative electrode and a positive electrode separated in the axial direction of the battery.
First and second springs for pressing both poles from both sides
Comprising a pole and an electrode moving means, and exhibiting a convex portion.
The second spring electrode that presses the positive electrode is the convex portion.
How to remove the battery at right angles to the axial direction through
And the electrode moving means is movable forward.
The second spring electrode is attached, and the above-mentioned holding is performed by an elastic biasing force.
It is designed to be movable in the detaching direction.

[0012]

According to the present invention, by pressing the electrode movable means having the leaf spring electrode downward, the pressed portions of the + electrode and the leaf spring electrode are released, and the holding of the battery is released. The battery moves to the + electrode side due to the reaction force of the spring electrode on the electrode side, and the + electrode side convex portion of the battery rides on the leaf spring electrode. When the released hand is released, the electrode moving means returns upward (original position) by the elastic urging force, and at the same time the battery is lifted, so that the battery can be easily removed.

[0014]

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention,
2 to 4 are sectional views taken along the line AA of FIG. 1. FIG. 2 shows a battery holding state, FIG. 3 shows a battery holding release state, and FIG. 4 shows a battery lifting state. FIGS. 5 and 6 are perspective views of the leaf spring electrode and the leaf spring electrode fixing part of this embodiment.

The battery to be mounted is, for example, the dry battery 1 shown in FIG. At both ends of the battery accommodating section 2, spring electrodes for pressing the positive electrode and the negative electrode of the dry battery 1 from both ends are attached. As the spring electrode, for example, a coil spring 3 is used on the minus electrode side, while a leaf spring electrode 4 made of a leaf spring is used on the plus electrode side. A coil spring 3 which is a spring electrode on the electrode side;
Performs an operation of moving the dry battery 1 to the positive electrode side by the urging force of the spring when the holding of the dry battery 1 is released.

The leaf spring electrode 4 for pressing the + electrode side is formed by cutting and bending a metal plate having a spring property. As shown in FIG.
And a battery lifting portion 4 as an end for lifting and moving the dry battery 1 in a direction perpendicular to the axial direction.
b. The leaf spring electrode 4 is integrally mounted on the leaf spring electrode fixing part 5.

FIG. 6 is a perspective view of a leaf spring electrode fixing part 5 as an electrode moving means. The leaf spring electrode fixing part 5 is slidably mounted on the + electrode side of the battery housing part 2 and has a coil for biasing and sliding the leaf spring electrode fixing part 5 itself in a direction perpendicular to the battery axis. The spring 6 is mounted.

The operation of the embodiment having such a configuration will be described below.

When the dry battery 1 is removed, the leaf spring electrode fixing part 5 is pushed by hand against the urging force of the coil spring 6 (FIG. 2). Then, the contact 4a of the leaf spring electrode 4 is
Contact with the positive electrode protruding portion 1a is released. As a result, the holding of the dry battery 1 is released, and at the same time, the dry battery 1 moves to the positive electrode side by the reaction force of the coil spring 3 on the negative electrode side, and the positive electrode protruding portion 1a of the dry battery 1 becomes the battery lifting portion 4b of the leaf spring electrode 4. (Figure 3). When the finger pressed from the leaf spring electrode fixing part 5 is released, the leaf spring electrode fixing part 5 moves by the urging force of the coil spring 6 and returns to the original position. Move upward while lifting 1.
The state shown in FIG. 4 is obtained. As described above, the dry battery 1 lifted up in the battery storage section 2 can be easily removed.

In the above embodiment, the plate spring electrode 4
5 is exemplified by the shape shown in FIG. 5, but the present invention is not limited to this, and any other shape may be used as long as it has a portion that presses the positive electrode side of the battery and a portion that lifts in the removal direction. Good.

Although a coil spring has been exemplified as the negative electrode side spring electrode, another spring electrode such as a leaf spring may be used.

[0023]

The first effect is that the operability of removing the battery is improved.

The reason is that a movable spring electrode having an electrode pressing portion and a portion to be lifted in the battery removing direction is adopted, and the battery is lifted in the storage section by simply pushing the electrode movable portion.
