FIG. 6 shows a sectional view of FIG. 4 and FIG.
4D is a sectional view taken along line AA of FIG. 4D, and FIG. 6B is a sectional view of FIG.
6C is a cross-sectional view taken along line CC of FIG. 4D, and FIG. 6D is a cross-sectional view taken along line dd of FIG. 4D.

The procedure for attaching the battery pack 2 to the portable radio telephone body 1 will be described with reference to FIG.
As shown in FIG. 1, a guide groove 12 is provided in the lower part of the telephone body 1. In a state where the guide claws 22 of the battery pack 2 are inserted into the guide groove 12 and hooked on each other, the battery pack 2 Is rotated toward the telephone body 1 and guided on an arc. Then, the battery pack 2 guided on the arc is
As shown in FIG. 6D, when the snap lever lock 21 on the battery pack 2 is pushed into the mounting portion of the telephone body 1, the snap lever lock 21 fits while being bent before being hooked on the lock dropout groove 11 provided in the telephone body 1, Finally, the snap lever lock 21 having a spring property is engaged with the drop groove 11 where the lock is hooked, and the battery pack 2 is mounted and held on the telephone body 1.

Further, in order to remove the battery pack 2 from the telephone body 1, the snap lever lock 21 of the battery pack 2 having the spring property and the drop groove 11 for engaging the lock of the telephone body 1 are forcibly engaged. Snap lever lock 2
1 can be deflected by a finger to make it open, and it can be removed by pulling it out in the reverse order of the mounting.

[0009]

The above-mentioned battery pack 2
According to the structure of the above, in the handling of the battery pack alone and the handling when attaching and detaching the battery pack to and from the telephone main body 1, the lock 21 of the snap lever having a spring property is erroneously lifted by a finger or the like in a direction opposite to the locking direction. If bent, the snap lever may be easily broken and broken. However, when the lock structure is changed for that purpose, it is difficult to reduce the number of parts and to improve the assemblability, and it is necessary to secure a space in a limited structure.

An object of the present invention is to prevent the lock of the snap lever integrated with the battery pack case from being broken by mistake in the above-described handling when the battery pack is used alone and when the battery pack is attached to and detached from the telephone body. In the offer.

[0011]

The above object is achieved by providing a structure in which a stopper is provided so that the snap lever integrated with the battery pack does not bend in the direction opposite to the locking direction.

[0012] According to the above means, in handling the battery pack alone and attaching / detaching to / from the telephone body,
Even if the snap lever is erroneously bent in the opposite direction to the lock, the bending is prevented by the stopper, and the snap lever is prevented from being damaged. This results in a durable and reliable structure for the lock.

[0013]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a state diagram of a portable radio telephone equipped with a battery pack according to one embodiment of the present invention, wherein (a) is a front view, (b) is a left side view, (c) is a right side view, (D) is a rear view. In the figure, the same symbols as those in FIG. 4 indicate the same parts.

FIG. 2 is a side view of the battery pack 2 having a battery pack-integrated lock 21 having a snap lever shape having a spring property at an upper portion, and a battery pack guide claw 22 at a lower portion. Further, a stopper 23 is provided so that the upper snack lever is not bent in the direction opposite to the locking direction.

Here, in order to integrate the snap lever-shaped lock 21 and the stopper 23 of the battery pack 2, the snap lever-shaped lock 21 is provided on the lid side of the battery pack case, and the stopper 23 is provided on the box side. Alternatively, the box and the lid are provided by welding or screwing or the like, and are structurally integrated by assembling them. 3 shows a cross-sectional view of FIG. 1, FIG. 3 (a) is a sectional view taken along line AA of FIG. 1 (d), FIG. 3 (b) is a sectional view taken along line BB of FIG. 1 (d), FIG. 3C is a sectional view taken along the line CC of FIG.
FIG. 2D is a sectional view taken along line dd of FIG.

Referring to FIG. 3, the procedure of mounting the battery pack 2 on the portable radio telephone body 1 will be described.
As shown in (b), the guide groove 12 at the lower part of the telephone body 1
With the guide claw 22 of the battery pack 2 hooked on the battery pack 2, the battery pack 2 is rotated toward the telephone body 1 with the fulcrum as a fulcrum to guide the battery pack 2 on an arc. Then, when the battery pack 2 is pushed into the telephone body 1 as shown in FIG. 3D, the snap lever lock 21 on the upper part of the battery pack 2 is bent and fitted before being engaged with the lock drop groove 11 on the telephone body 1 side. Eventually, the snap lever lock 21 engages with the drop groove 11 where the lock is hooked by the spring property, and the battery pack 2 is mounted and held on the telephone body 1.

Further, the battery pack 2 is detached from the telephone body 1, and the snap lever lock 21 of the battery pack 2 having a spring property and the drop groove 1 in which the lock of the telephone body 1 is hooked.
1 is forcibly engaged with the snap lever lock 21.
Can be removed by bending it with a finger to make it open, and pulling it out in the reverse order of mounting.

In handling the battery pack 2 as a single unit and in attaching and detaching it to and from the telephone body 1,
Even when the springy snap lever 21 is flexed in the opposite direction to the locking direction by mistake, the stopper 23 integrated with the snap lever lock 21 is provided on the battery pack 2 so that the snap lever is moved in the reverse direction by the stopper. Bending is prevented, and breakage is prevented.

In the portable radio telephone according to the present invention, a battery pack is mounted as a power source. The battery pack has a lock structure that can be easily attached and detached when the battery pack is replaced with the phone body, and a lock integrated with the lock provides a durable and reliable lock that does not break the snap lever. Becomes

[0021]

As described above, according to the present invention, the lock structure for mounting the battery pack on the portable radio telephone is easy to attach and detach with a simple snap lever shape lock structure integrated with the case. By providing the integrated stopper, the snap lever is prevented from being broken by an erroneous operation when the battery pack is attached or detached, and a highly durable lock structure can be obtained.
