DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable terminal such as a portable telephone.

[0002]

2. Description of the Related Art FIG. 10 shows an example of a conventional portable telephone. This portable telephone comprises a telephone shell 3 composed of a front shell 1 and a rear shell 2, and a power supply for transmission and reception. And a battery outer shell 4 containing a battery to be obtained.

A key (not shown) used for input setting of a destination telephone number and the like, and a liquid crystal display (not shown) for displaying the input set telephone number and received information are provided on the outer shell front portion 1. Equipped.

[0004] An antenna 5 is provided at a tip end of the outer shell rear portion 2, and a battery housing concave portion 6 recessed toward the outer shell front portion 1 is formed at a portion near a base end of the outer shell rear portion 2. .

[0005] A battery outer shell 4 is mounted on the outer shell rear portion 2 so as to be in contact with the opening edge of the battery housing concave portion 6, and closes the battery housing concave portion 6. And a battery inner body 8 fitted into the battery storage recess 6.

At the base end of the lid 7, a projection 10 is provided which can be engaged with a recess 9 formed on the end face of the outer shell rear part 2 on the side opposite to the antenna-equipped end. A protrusion 12 is provided which can be engaged with a hole 11 formed in the inner wall of the battery housing recess 6 on the antenna 5 equipment side, and the protrusion 10 is provided in the recess 9.
Cover 7 so that projection 12 faces hole 11.
Is brought into contact with the periphery of the battery housing concave portion 6 as shown by a two-dot chain line in FIG.
When pushed out toward the end of the antenna 5 (in the direction of the arrow a in FIG. 10), the projections 10 and 12 engage with the recess 9 and the hole 11,
The battery outer shell 4 is attached to the outer shell rear portion 2.

When the battery outer shell 4 is taken out, the lid 7 is pushed out toward the antenna-equipped end side of the outer shell rear portion 2 so that the engagement between the recess 9, the hole 11 and the projections 10 and 12 is released. Thus, the battery outer shell 4 can be removed from the outer shell rear portion 2.

A hook 14 extending from the inner bottom surface of the battery housing recess 6 to the opening edge and having a recess 13 recessed toward the antenna 5 equipment end is integrally formed on both inner wall surfaces of the battery housing recess 6. In addition, on both outer wall surfaces of the battery inner body 8, there are a recess 9, and a projection 15 that can engage with the recess 13 of the hook 14 when the hole 11 engages with the projections 10 and 12. The hook 16 is formed integrally.

When these hooks 14 and 16 are engaged with each other, the power receiving contact 17 provided on the inner bottom of the battery housing recess 6 causes the power feeding contact 18 of the battery inner body 8 to move outside the outer shell rear portion 2. The battery shell 4 is prevented from warping due to being pushed out.

[0010]

However, FIG.
Since the lid 7 is slid with respect to the rear part 2 of the battery when the battery shell 4 is attached and detached, the mobile phone shown in FIG. A gap 19 corresponding to the moving distance of the lid 7 needs to be set between the end wall near the antenna 5 and the overall length of the mobile phone tends to be longer due to the influence of the gap 19.
