Abstract

PROBLEM TO BE SOLVED: To provide a mobile telephone handset for increasing the degrees of freedom in design and facilitating the design by providing an outer side housing provided with a rear component and a front component, providing the front component with a skirt part on the outer periphery and forming the skirt part to have and be overlapped with the periphery of the rear component. SOLUTION: This handset is provided with the outer side housing constituted of two molded parts composed of the rear component 10 and the front component 11. The front component 11 is provided with a skirt part 11a on the outer periphery, and the skirt part 11a receives the outer periphery of the rear component 10 and is fitted to it. The front component 11 is fixed onto the rear component 10 by three integrated type clips and a pair of screw components. One clip is formed by a tongue piece part turned to the inner side of the skirt part 11a at one end of the front component 11. For the shape of the front component 11, a front surface is nonlinear and the free end edge of the skirt part 11a is also nonlinear. By changing the shape of the front surface of the front component 11 and the free end edge of the skirt part 11a, marked deformation is given to the appearance of the handset.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to mobile telephone handsets.

[0002]

2. Description of the Related Art Various types of portable small electrical devices are known. In conventional mobile telephone handsets, as well as their electrical devices, the outer housing is made of two cowhide-shaped moldings, the edges of which are brought together.

[0003]

Conventional handsets made in the manner described above are limited in the applicable designs. For example, if a manufacturer wants to make a group of telephone handsets with substantially different appearances, it is necessary to make both molds differently for each design. This means that it is necessary for the manufacturer to make many different outer housing molds and store them.

In addition, if the two outer housing molds are made of materials having different colors or different appearances, the designer will have a non-linear mating edge, thus complicating the design.

[0005] It is therefore an object of the present invention to provide a mobile telephone handset with increased design flexibility and ease of design.

[0006]

According to the present invention, there is provided an outer housing including a rear part and a front part, wherein the front part has a skirt on its outer periphery, and the skirt is provided on the rear part of the rear part. A mobile telephone handset is obtained, characterized in that it is shaped to receive and surround itself.

[0007] Preferably, said skirt component has a non-linear edge.

[0008] Further, it is preferable to include a telephone printed circuit board attached to the rear part to form a telephone core, and a cover for covering the same.

A keypad printed circuit board with a display device located between the cover and the inside of the front part;
A keypad having a key protruding into a hole in said front part.

[0010] The keypad may be between the keypad printed circuit board and the front part.

[0011] Further, a keypad film may be provided between the keypad printed circuit board and the keypad.

[0012]

1 to 5 show a mobile telephone handset according to an embodiment of the present invention. This handset has an outer housing composed of two molded articles consisting of a rear part 10 and a front part 11. As can be seen from FIGS. 2 to 5, the rear part 10 is a printed circuit board 12 of the telephone.
And another cover 13 made of a molded product covering the same, and is fixed to the rear part 10. These printed circuit boards 1
2 and cover 13 together form the basic core of the handset.

Another keyboard printed circuit board 14 with a display device
Is disposed between the cover 13 and the front part 11. A keypad film 15 is disposed between the keypad 16 and the printed circuit board 14. The keypad 16 has a key portion projecting through a hole in the front part 11.

The front part 11 has a skirt 11a on its outer periphery.
Having. As can be seen from FIGS.
1a receives the outer periphery of the rear part 10 and fits therein. The front part 11 is fixed on the rear part 10 by three integrated clips and a pair of screw parts. One clip is a tongue piece 1 at one end of the front part 11 facing the inside of the skirt 11a.
1b (see FIG. 4). The clip comprising the tongue piece 11b is received in a corresponding undercut groove formed on the outer periphery of the rear part 10. The other two clips are formed by lower ribs 10a and 10b on the outer peripheral side of the rear part 10. These clips consisting of ribs 10a, 10b are received in corresponding undercut grooves formed on the inner surface of the skirt portion 11a (see FIG. 3). As shown by the arrow 17 in FIG. 2, the threaded part is passed through a hole formed inside the rear part 10 adjacent to the opposite end thereof and further formed on a boss formed inside the skirt part 11a of the front part 11. It is inserted in the receiving hole.

As can be seen from FIG. 5, the front part 11 has a non-linear front surface and a non-linear free edge of the skirt portion 11a. The shape of the front of the front part 11 and the skirt 11
By changing the free edge of a, a significant deformation can be given to the appearance of the handset. Instead of the edges being butt-to-edge as in the prior art, the skirt 11a
Has a structure that overlaps with the rear part 10, so that the deformation of the rear part 10 and the telephone core can be obtained without the need for redesign or rework.

Since the keypad 16 does not form part of the telephone core, the designer can change the appearance of the handset by changing the design of the keypad 16. The shape of the keys can be changed, and the holes for the keys can be changed accordingly.

[0017]

As described above, according to the present invention,
It is possible to provide a mobile telephone handset that has an increased degree of freedom in design and is easy to design.
