Description

[Detailed explanation of the idea] The present invention relates to a battery fixing structure.

A conventional battery fixing structure is shown in FIGS. 1 and 2. In FIG. 1, the battery 1 is in contact with the battery negative terminal 4 from below, and the battery fixing member 2 is seen from the side.
It is pressed and fixed against the wall 5a of the main plate 5. However, while this structure has the advantage that the battery can be easily installed from above, it is pushed upward by the spring force of the battery negative terminal 4 from below, so the battery can easily pop out due to a slight impact, etc. There were many problems with the assembly.

On the other hand, in FIG. 2, the battery 1 is fixed from above by a battery fixing member 2, and the battery fixing member 2 is securely fixed to the base plate 5 etc. with screws 3, so in this structure, the battery does not pop out. Never. However, this structure has the disadvantage that when attaching or detaching the battery, the screw 3 must be removed and the battery fixing member 2 must be removed, which requires a great deal of effort for disassembly and assembly.

In order to eliminate the above-mentioned drawbacks, the present invention securely holds the battery with only one battery fixing member, allows the battery to be attached and removed without removing the battery fixing member from the watch body, and allows the battery to be installed easily. The purpose is to reduce labor and securely secure the battery.

The present invention will be explained in detail below with reference to FIGS. 3 and 4.

1 is a battery; 2 is a battery fixing member, which has a holding part 2a for fixing the battery from above; another fixing part 2b having spring properties for fixing the battery from above; and a part 2c for guiding the tip 2d of the fixing part 2b. . 4 is the negative terminal of the battery, and 5 is the ground plate. The battery fixing member 2 is fixed to the base plate 5 with a plurality of screws 3. In this structure, the tips 2d of the battery fixing members are engaged with the fixing portions 2c so as to wrap around them, making it difficult for them to move upward and toward the outside of the battery.

Next, to explain how to assemble the battery, tilt the battery slightly and put one edge of the battery under the battery fixing member 2a, and then press the battery downward, and the battery fixing member 2b will have a spring property. When the battery is pushed further downward, the battery fixing member 2b returns to its original position on the upper surface of the battery due to its spring property, and the battery fixing member Since the tip 2d of 2b is engaged with the fixing part 2c, it does not bend upward and the battery can be held securely.

On the other hand, when removing the battery, by pushing the fixing part 2b of the battery fixing member toward the outer circumference of the battery, the battery will float upward with the help of the repulsive force of the negative battery terminal 4, and can be easily removed.

As described above, according to the present invention, since it is possible to attach and detach the battery using a single battery fixing member without removing the battery fixing member, the effort of disassembling and assembling can be reduced and the battery can be completely retained. have

Note that by connecting the battery fixing member with an integrated circuit, it can also function as a battery positive terminal at the same time.

Claims (1)

[Scope of utility model registration request] A small electronic device that operates by obtaining electrical energy from a battery includes a holding part that presses one end of the top surface of the battery, and a spring that is provided on a part of the top surface of the battery opposite to the holding part so that it can be elastically deformed in the direction of the outer circumference of the battery. The spring part is elastically deformed along the outer surface of the battery when the battery is stored, and after the battery is stored, the spring part and the pressing part deform the battery fixing member integrally with the upper surface of the battery. A battery fixing structure characterized in that the battery is supported by holding down each part.
