報参照）。2. Description of the Related Art For example, a printed circuit board of an electronic device such as a mobile phone is provided with a memory, and a button type battery is used as a backup power source for the memory. The battery holder plays a role of bridging the power supply between the substrate circuit and the button-type battery. Regarding this battery holder, it is important that the stored button-shaped battery does not easily come off even if it receives shock or vibration, especially when it is used for an electronic device that is susceptible to relatively large shock or vibration such as a mobile phone. Required as basic performance. In a conventional battery holder, a block-shaped holding portion for attaching a contact that is in conductive contact with the button-type battery is formed in the holder body that houses the button-type battery in order to satisfy the detachment prevention performance of the button-type battery ( (1st prior art), an arc-shaped peripheral wall surrounding the peripheral side surface of the button type battery in the circumferential direction is provided vertically (2nd prior art), and a button is provided on the block-shaped holding portion or the arc-shaped peripheral wall. There is a type in which a locking claw is formed on the upper surface of a battery.

を強いられる。However, in the first prior art, since a locking claw is formed on a highly rigid block-shaped holding portion, it is positioned in advance above a regular accommodation position. Unless the button type battery is pushed in from the state, there is a problem that it is hard and difficult to be housed in the holder body. In particular, if the button-type battery is a small size with a diameter of 5 mm or less that is difficult to handle, a great deal of labor is required even if it is manually housed.

きくなってしまうという問題もある。Further, in the second prior art, even if the button-shaped battery is slightly deviated from the proper accommodation position, the arc-shaped peripheral wall is slightly bent outward when the button-shaped battery is pushed in. Therefore, the hardness at the time of pushing is reduced as compared with the first related art. However, in this conventional technique, if the button-type battery is relatively larger than the accommodation space of the holder main body due to a dimensional error of the button-type battery or the resin-molded holder main body, the arc-shaped peripheral wall suspended from the holder main body. Are continuously pressed outward by the button-type battery, and are forcibly bent. Then, there is a problem that cracks are likely to occur near the base of the peripheral wall, and the button-type battery is detached with a slight impact because it is locked by point contact on the upper surface of the button battery with the locking claw on the peripheral wall warped upward There is a problem that it is easy to do. In addition, since the arc-shaped peripheral wall surrounds the peripheral side surface of the button-type battery, the holder body must be formed in a larger size than the button-type battery, and the mounting area increases accordingly. There is also.

An object of the present invention is to provide a battery holder that can prevent the battery holder.

る。In order to achieve this object,
A battery holder according to the present invention is characterized in that, in a battery holder in which a lock portion that locks on an upper surface of a button-shaped battery is formed in a holder main body that houses the button-shaped battery, the lock portion is formed in a column shape outside a normal storage position of the button-shaped battery. And the opposite surface of the lock portion facing the peripheral side surface of the button-shaped battery is formed so as to fall down toward the center of the button-shaped battery.

何れでもよい。In this battery holder, since the lock portion is formed in a pillar shape outside the proper housing position of the button-shaped battery, the lock portion can be locked even if the button-shaped battery is pushed in from a position slightly deviated from the proper housing position. The flexibility of the part is high and can be flexed softly. Therefore, compared with the block-shaped holding portion (first conventional technology) and the peripheral wall (second conventional technology),
The mounting flexibility can be reduced by the high flexibility. In addition, since the opposing surface of the lock portion facing the peripheral side surface of the button type battery is depressed toward the center of the button type battery, the amount of flexure of the lock portion is correspondingly large. Therefore, due to the dimensional error of the button type battery or the holder main body, the button type battery is relatively larger than the housing space of the holder main body, and even if the lock type portion receives continuous pressing from the stored button type battery, large bending occurs. The dimensional error can be absorbed by the amount, and the occurrence of cracks near the base of the lock portion can be prevented. The cross-sectional shape of the columnar lock portion may be any one of a regular polygonal shape, an irregular polygonal shape, a perfect circular shape, an elliptical shape, and a composite shape thereof.

等による衝撃を受けてもボタン形電池が離脱しない。Due to the dimensional error of the button-type battery or the resin-molded holder main body, for example, the upper surface position of the button-type battery becomes higher in the height direction than the regular housing position, or it becomes larger than the housing space of the holder main body. Also, the button-type battery may be relatively large, and may be warped by continuous pressing from the button-type battery housed in the lock portion. In the present invention, a claw portion for suppressing the upper surface of the button-shaped battery is protruded from the opposite surface of the lock portion, and the locking surface of the claw portion that locks on the upper surface is formed by inclining downward. Even in this case, the locking is performed in a point contact state or a surface contact state in which the locking surface is inclined downward with respect to the upper surface of the button type battery. Therefore, a sufficient locking force can be exhibited, and the button-type battery does not come off even if it receives an impact due to a fall or the like.

強することができる。Since the holding wall partially surrounds the peripheral side surface of the button type battery in the circumferential direction, it is possible to prevent the button type battery from being detached from the proper storage position even when an impact due to a drop or the like is applied. Further, since the holding wall is integrally formed at a height lower than the height of the lock portion, the flexibility of the lock portion is hardly hindered, and the lock portion can be reinforced against excessive bending or external force.

も防止できる。(2). For example, as shown by a two-dot chain line in FIG. 6 (a), in the case of a lock portion 5 'formed vertically without inverting the facing surface 5a', the button type battery B and the holder body 2 '
When the button-shaped battery B is continuously pressed from the stored button-type battery B due to the dimensional error of, the lock portion 5 ′ largely warps outward as shown by a solid line. This may cause cracks due to stress concentration near the base. However, as shown by the two-dot chain line in FIG. 6B, the lock portion 5 of this embodiment has the opposing surface 5 a facing the peripheral side surface Bs of the button type battery B inward in the direction of the center point P 1 of the button type battery B. Since it is tilted down, the amount of bending of the lock portion 5 is large.
Accordingly, the button-type battery B is slightly larger than the accommodation space of the holder body 2 due to the dimensional error of the button-type battery B and the holder body 2, and even if the button-type battery B is continuously pressed from the accommodated button-type battery B, a large amount of bending is caused. Accordingly, the dimensional error can be absorbed, and the generation of cracks near the root of the lock portion 4 can be prevented.

ックの発生も防止できる。According to the battery holder of the present invention, since the lock portion is formed in a column shape outside the proper storage position of the button-shaped battery, the button-shaped battery is pushed from above in a state slightly deviated from the proper storage position. Even when the button-shaped battery is inserted, the button-shaped battery can be accommodated by flexing the lock portion with high flexibility. In addition, since the opposing surface of the lock portion facing the peripheral side surface of the button type battery is depressed toward the center of the button type battery, the amount of flexure of the lock portion is correspondingly large. As a result, the button-type battery is slightly larger than the housing space of the holder body due to the dimensional error of the button-type battery and the holder body, and even if the button-type battery is continuously pressed by the stored button-type battery, the dimensional error is absorbed by the large bending amount. It is possible to prevent the occurrence of cracks near the base of the lock portion.
