STRUCTURE OF BAND WHICH CONNECTS MAIN BODY OF WATCH-TYPE MOBILE COMMUNICATION TERMINAL}

The present invention relates to a structure of a band connected to the terminal body in a wristwatch type mobile communication terminal, and more particularly, to a band structure in which a key input unit is provided in the band.

In a wristwatch-type mobile communication terminal, keys for inputting key data of a user are conventionally provided in a terminal body. Alternatively, these keys are separated from the terminal body and provided in a separate housing.

1 illustrates an example of a conventional wrist watch-type mobile communication terminal.

Since it must be worn on the wrist, the terminal body 101 is manufactured with a smaller volume and weight than a typical portable mobile communication terminal. Therefore, as shown in the drawing, when the key input unit 103 for the user's key data input is provided in the terminal main body 101, each key does not have sufficient space, and thus the user can conveniently press the key. none. In addition, in manufacturing the terminal body 101, mechanical restrictions are imposed.

In the related art, when the key input unit 103 is separated from the terminal body 101, a housing for the key input unit 103 must be separately provided in the band 105 (not shown in FIG. 1). A lot of spatial constraints are caused by separate housing.

In view of recent technical trends for miniaturizing a terminal body and a simple design, a wristwatch-type mobile communication terminal according to the conventional technology is not competitive.

Therefore, the present invention is provided with a plurality of keys that the user can select and press on the upper surface of the case of the band, the flexible printed circuit as a printed circuit board to generate an electrical signal according to the user's key press operation inside the band. (F-PC), and one side of the flexible printed circuit extends outward through a hole formed in the band case, and one end of the flexible printed circuit has a connector for electrical connection with the terminal body. The present invention provides a structure of a band connected to a terminal body in a wristwatch type mobile communication terminal.

The present invention for achieving the above object, in the structure of the band connected to the terminal body in the wristwatch-type mobile communication terminal, the keypad is provided inside, the keys of the keypad are formed on the upper surface of the case of the band Is inserted into each of the holes to protrude to the outside, the inside of the band is provided with a flexible printed circuit for generating an electrical signal according to the user's key press operation, one side of the flexible printed circuit is formed in the band case It extends to the outside through a hole, characterized in that a connector for electrical connection with the terminal body is provided at one end of the flexible printed circuit.

1 is an example of a conventional watch-type mobile communication terminal.

Figure 2 is a perspective view of the band according to the present invention.

3A and 3B are exploded perspective views of a band according to an embodiment of the present invention, respectively.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

Figure 2b is a perspective view of the band according to the present invention, Figure 3a and Figure 3b is an exploded perspective view of the band according to an embodiment of the present invention, respectively. Hereinafter, this will be described with reference to FIGS. 2, 3A, and 3B.

The band 210 is connected to the terminal body (not shown) and is worn on the user's wrist. A plurality of keys 201 are provided on the surface portion of the band 210. A printed circuit board 207 provided inside the band 210 and generating key data corresponding to a specific key pressed by a user is called a flexible printed circuit (F-PC). Use.) As is well known, F-PC has a film attached to both sides of flexible metal foil circuit, and its thickness is 50 ~ 300㎛ so thin that it is hard to apply rigid printed circuit board. It is mainly used for.

As shown in FIG. 2, one side of the F-PC 207 extends to the outside through a hole formed in the band 210 case, and one end of the F-PC 207 is electrically connected to the terminal body. A connector 209 is provided for the connection.

The terminal body is provided with a voice processor, a wireless signal processor, a central controller, a screen window, a memory, and the like, and these components are mounted on a main printed circuit board (not shown) inside the terminal body. The connector 209 is connected to the male / male connector of the main printed circuit board provided in the terminal body. (Not shown.) Key data generated from the F-PC 207 is connected to the terminal body through the connector 209. Is provided.

3A is an exploded perspective view of the band 210, the outer case of the band 210 is composed of an upper case 301 and a lower case 315, the upper / lower case is coupled by fastening the screw in the vertical direction (Not shown) The band 210 may be made of a silicone material having good elasticity so that the user may feel fit.

As shown in the figure, a plurality of holes are formed in the face portion of the upper case 301 corresponding to the arrangement of the keys. The keypad 305 is provided with a combination of numeric keys and various function keys, and when assembled, each key protrudes out through a corresponding hole on the upper case 301 surface. The dome (Metal Dome) 309 has an elastic force so that the user can get a feeling of operation when the key is pressed.

The F-PC 207 is provided with a plurality of switching terminals. When the corresponding switching terminals are contacted according to a user's key pressing operation, the F-PC 207 generates a corresponding key input signal (electrical signal), and the connector Through 209 to the terminal body (not shown).

The upper and lower plates 303 and 313 are formed of a thin press to protect components inside the upper and lower cases 301 and 315 and to increase a user's wearing comfort. The backlight 307 is formed of an electroluminescent lamp (EL) lamp having a sheet shape. If necessary, an LED (not shown) mounted on the F-PC 207 may replace the backlight 307. Unexplained reference numeral 205 is a microphone, which is installed on the other side of the F-PC 207 opposite the connector 209.

Figure 3b is an exploded perspective view of the wrist band according to another embodiment of the present invention. Hereinafter, a description will be given with reference to FIG. 3A.

Referring to the characteristic of FIG. 3B, the key 203 provided on the surface portion of the band 220 is not formed on the keypad 305 as shown in FIG. 3A, but is integrally formed on the upper case 317. 3A and 3B are the same as shown in FIG. 2 when viewed from the outside in the combined state, respectively.) In order to manufacture such an upper case 317, a double injection method is used. The key 201 part uses a soft material as compared to the other parts. The color of the key and the color of the remaining parts may be different. The configuration of FIG. 3B integrates the keys 201 provided on the face of the band 220 with the outer case 317 to protect the product from water or other foreign objects.

As described above, the present invention is provided with a plurality of keys that the user can select and press on the upper surface of the case of the band, the inside of the band is flexible as a printed circuit board to generate an electrical signal according to the user's key pressing operation A printed circuit board (F-PCB) is used, and one side of the flexible printed circuit board extends to the outside through a hole formed in the band case, and one end of the flexible printed circuit board is electrically connected to the terminal body.
