[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery pack fixing device for a portable telephone.

[0002]

2. Description of the Related Art Generally, a mobile telephone 30 is a telephone body 3
The battery pack 32 is fixed to the battery pack 1. This fixing is performed by the battery pack mounting portion 3 provided on the telephone body 31.
3 is provided with a fixed hook 34 and a movable hook 35, and these hooks 34, 35 are engaged with engagement recesses 36, 37 formed on both end surfaces of the battery pack 32. As shown in FIG. 3B, the mechanism of the movable hook 35 includes a bearing portion 39 provided at the bottom of the movable hook housing portion 38 provided with the telephone body 31 and a movable hook 35 having a claw portion 40. The support shaft 42 is supported, and the torsion spring 43 provided on the support shaft 42 urges the movable hook 35 toward the battery pack mounting portion 33 (D direction).
The lock release button 45 is brought into contact with the pushing portion 44 provided on the back portion of No. 5.

Then, one of the engaging recesses 36 of the battery pack 32 is engaged with the fixed hook 34, and the battery pack 32 is rotated toward the battery pack mounting portion 33 side (direction A) using this engaging point as a fulcrum. By doing so, the corner portion 32a of the battery pack 32 pushes the arcuate portion 40a on the upper surface of the claw portion 40 of the movable hook 35, and the movable hook 35 resists the torsion spring 43 to move in the counterclockwise direction (in FIG. 3B). B
Direction) to move the battery pack 32 along the battery pack mounting portion 33, and the movable hook 35 is pushed by the spring force of the torsion spring 43 to engage the claw portion 40 with the other engaging recessed portion 37 so that the battery pack 32 is secured. It is mounted on the battery pack mounting portion 33.

When the battery pack 32 is removed from the battery pack mounting portion 33, the lock release button 45 is pushed to rotate the movable hook 35 counterclockwise around the support shaft 42 as a fulcrum. The torsion spring 43 is compressed and the claw portion 40 is removed from the engagement recess 37. In this state, the battery pack 32 is rotated in a direction in which the battery pack 32 is separated from the battery pack mounting portion 33 with the engaging point on the fixed hook 34 side as a fulcrum, and the battery pack 32 is rotated from the fixed hook 34.
Remove.

[0005]

However, in the above-described conventional battery pack fixing device, since the movable hook 35 is configured to rotate only, the portable telephone 3
When 0 is dropped or the telephone pack 32 is intentionally pulled in the C direction, the movable hook 35 rotates and the claw portion 40 is disengaged from the engaging recess 37, and the battery pack 32 falls off. It was

Further, recently, as the size and weight have been reduced, the elasticity of the torsion spring 43 that holds down the movable hook 35 cannot be increased, and in this case, if a certain amount of stress is applied, the battery pack 32 will fall off. there were.

The present invention has been made in view of the above-mentioned problems, and an object thereof is to enable a movable hook to be operated by a spring having a low elasticity, so that the battery can be reliably stored in a small space. An object of the present invention is to provide a battery pack fixing device for a mobile phone, which can hold the pack, reduce the pressing force of the lock release button, and improve operability.

[0008]

In order to achieve the above object, the present invention provides a movable hook accommodating portion in a telephone body having a battery pack mounting portion, and the movable hook accommodating portion has a movable hook accommodating portion. A bearing having a long insertion part in a direction perpendicular to the bottom is provided, a protrusion is provided on the upper surface of the movable hook accommodating part, and a movable hook exposing part is provided on the battery pack mounting part side of the movable hook accommodating part. A movable hook having a claw portion is formed in the movable hook accommodating portion, the spindle of the movable hook is inserted into the bearing portion, and the movable hook is lifted by a spring to project the claw portion from the movable hook exposing portion. It was made.

[0009]

With this structure, when the mobile phone is dropped or the phone pack is intentionally pulled, a strong stress is applied to the phone pack, and the movable hook is lifted up via the claw part engaged with the engaging recess. The support shaft contacts the upper edge of the bearing, and the upper end of the claw collides with the protrusion to prevent the movable hook from rotating, preventing the claw from coming off the battery pack and firmly holding the battery pack. be able to. Therefore, the movable hook can be operated by the spring having a low elasticity, and the battery pack can be reliably held in a small space. As a result, the pressing force of the lock release button can be reduced and the operability can be improved.
