Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a detachable device for attaching and detaching a battery pack to and from a portable telephone.

[0002]

2. Description of the Related Art As shown in a sectional view of FIG. 4, a mounting portion of a battery pack in a conventional portable telephone has a locking recess 3 at one end of a battery pack 1 and a locking projection at the other end. On the other hand, on the side wall 5a side of the telephone body 4, a locking claw 7 that engages with the locking recess 3 on the battery pack 1 side is provided via a spring 8 so as to be able to advance and retreat. On the 5b side, a locking recess 6 for engaging the locking projection 2 on the battery pack 1 side is provided.

When the battery pack 1 is mounted on the telephone body 4, the locking projection 2 on the battery pack 1 is inserted into the locking recess 6 on the telephone body 4 as shown in FIG. After the engagement, the locking recess 3 side of the battery pack is pushed into the mounting recess 5, so that the lower end 3 a of the locking recess 3 presses the inclined surface 7 a of the locking claw 7 to reduce the elastic force of the spring 8. When the locking claw 7 is retracted and the battery pack 1 is completely pushed into the mounting recess 5, the locking claw 7 advances by the elastic force of the spring 8 and the locking recess 3 of the battery pack 1 is moved. , And is mounted.

When the battery pack 1 is detached from the telephone body 4, the locking claw 7 is released by manually retracting the locking claw 7 against the elastic force of the spring. ,
It can be lifted up and removed.

[0005]

However, in the above-mentioned conventional portable telephone, if the battery pack 1 is accidentally dropped on the floor or the like when the battery pack 1 is attached or detached, the projection 2 formed at one end of the battery pack is formed. , There is a problem of being damaged by impact.

The present invention has been made in view of the above problems, and has as its object to provide a battery pack attaching / detaching apparatus which does not break even when the battery pack is subjected to an impact such as dropping.

[0007]

According to a first aspect of the present invention, there is provided a battery pack attaching / detaching apparatus for mounting a battery pack in a battery pack mounting recess formed in a portable telephone body. Battery pack locking claws formed on both side walls of the concave portion, each of which has a tip formed on an inclined surface facing obliquely downward, are provided so as to be able to advance and retreat via a spring. A locking recess is provided to engage with each of the hooks, and the battery pack is detachably attached to the telephone body by the hook and the hook.

According to the first aspect of the present invention, since the locking portions formed at both ends of the battery pack in the battery pack mounting portion of the portable telephone are formed in the concave portions, the conventional projection is eliminated. There is no danger that the projection may be damaged even if it receives an impact such as a drop.

The battery pack 1 is provided with locking claws which move forward and backward via springs on both side walls of the battery pack mounting recess 5 on the telephone body 4 side.
Locking claw 7 even if it is pushed in while being kept parallel to
And 9 are retracted against the elastic force of the spring, thereby enabling mounting. When the battery pack 1 is to be removed, the locking is released only by retreating the locking claw 7 by hand against the elastic force of the spring, and the battery pack 1 can be removed by lifting its side. This makes attachment and detachment simple and reliable.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. In the drawing, the same components as those shown in the drawings of the conventional example are denoted by the same reference numerals, and the description thereof will be omitted.

(Embodiment 1) FIGS. 1 and 3 relate to Embodiment 1 of the present invention. FIG. 1 is a cross-sectional view of a mobile phone with a battery pack mounted thereon, and FIG. 2 is a cross-sectional view showing the mounting of the battery pack. FIG. 3 is a plan view of a mobile phone equipped with a battery pack.

FIG. 1 shows a battery pack attaching / detaching apparatus according to the present invention.
As shown in the figure, a battery pack mounting recess 5 is formed on the body 4 side of the mobile phone, and a battery pack locking claw 7 is provided on a side wall 5a of the recess 5 via a spring 8 so as to be able to advance and retreat, and on the side wall 5b. Is provided with a battery pack locking claw 9 via a spring 11 so as to be able to advance and retreat, and a battery pack locking claw 7 on the telephone body 4 side at one end of the battery pack 1.
Is provided with a locking concave portion 3 for engaging with the battery pack locking claw 9 at the other end.

At the tip of each of the battery pack locking claws 7 and 9, slanting surfaces 7a and 9a are formed diagonally downward, and the concave portions 3 and 10 formed at both ends of the battery pack 1 are Locking claws 7 and 9
Battery pack 1 has a shape capable of engaging each of
Is provided at a position in the up-down direction in which it can be securely mounted in the mounting recess 5 on the telephone body 4 side.

In this configuration, when the battery pack 1 is mounted on the telephone main body 4 side, the battery pack 1 is pushed in while being kept parallel to the telephone main body 4.
When the inclined surfaces 7a and 9a of the battery pack locking claws 7 and 9 are pressed, the battery pack locking claws 7 and 9 retreat against the elastic force of the spring, and at the position where the battery pack 1 is completely pushed in, the locking claws 7
And 9 are advanced by the elastic force of the spring to engage with the concave portions 3 and 10, and the mounting is completed.

When removing the battery pack 1,
By retreating the battery pack locking pawl 7 by hand against the elastic force of the spring 8, the locking by the locking pawl 7 is released, and the side can be lifted and removed.

The battery pack attaching / detaching device of the present invention can be applied not only to a portable telephone but also to an attaching / detaching device in other devices.

[0017]

According to the present invention, the structure of the mounting portion for mounting the battery pack on the portable telephone is advanced and retracted by the springs 8 and 11 on both side walls 5a and 5b of the battery pack mounting concave portion 5 of the telephone body. By providing locking pawls 7 and 9 that move, and by providing concave portions 3 and 10 at both ends of the battery pack 1 with which the locking pawls 7 and 9 can engage, a protrusion is provided on the battery pack side. Thus, even if the battery pack is accidentally dropped, there is no danger that the locking portion will be damaged by the impact, and the battery pack can be easily and securely attached to the telephone body.
