Description

WATCH-TYPE MOBILE COMMUNICATION TERMINAL}

The present invention relates to a wristwatch-type portable terminal, in particular, a key input unit is provided in a wrist band, a component is built in a space inside a case of a multi-function key provided in the terminal body, and a key for selecting a center is located on the upper surface of the multi-function key. An input configuration is made of a single component, and a wire antenna is embedded in the wristband case, and a wristwatch type portable terminal having a packaged battery.

The portable terminal refers to a mobile phone, a hand-held fish (HPC), a web-pad (WEP PAD), a personal digital assistant (PDA), and the like. Currently, such portable terminals have become small enough to be worn on the wrist according to the trend of high sensitivity, miniaturization and light weight of electronic components.

In order for a wristwatch-type portable terminal to be competitive in products, the main body of the terminal should be simplified and downsized, there should be no burden to wear on the wrist, the key operation should be convenient, and the production should be easy.

Hereinafter, problems of the conventional wrist watch-type portable terminal will be described in detail with reference to the accompanying drawings.

First, in the wrist watch type portable terminal, keys for inputting key data of a user are conventionally provided in the terminal body or these keys are separated from the terminal body and provided in a separate housing.

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

The wristwatch type portable terminal is composed of a terminal body 110 and a band 120. Since it must be worn on the wrist, the terminal body 110 is manufactured in a smaller volume and area than a general portable terminal. Therefore, as shown in the drawing, when the key input unit 103 for the user's key data input is provided in the main body of the terminal 110, since each key does not have enough space, the user can conveniently press the key. none. In addition, the manufacturing of the terminal body 110, subject to mechanical restrictions.

In the related art, when the key input unit 103 is separated from the terminal body 110, a housing for the key input unit 103 must be separately provided in the band 120 (not shown in FIG. 1). A lot of spatial constraints are caused by separate housing.

As described above, the conventional wrist watch-type portable terminal has a problem in that key input is inconvenient. In addition, in view of recent technical trends for miniaturizing a terminal body and a simple design, a wristwatch-type portable terminal according to the related art is not competitive.

On the other hand, the terminal body 110 is worn on the user's wrist. At this time, when the user wears the main body, it is important to consider not to feel a burden for improving the competitiveness of the product.

As illustrated, various components such as a key input unit 103, a screen window 109, a speaker 105, and the like are provided in the front housing of the terminal body 110. However, in order to provide these components in the front housing, the front housing should be designed as wide as the area occupied by each component. That is, since the area of the front housing should be as large as the parts occupy, there is a problem that the user feels a burden to wear the main body 110.

Meanwhile, Korean Laid-Open Utility Model Publication No. 2000-005501 discloses a technology related to a multi-function key in which a plurality of function keys mounted at mutually distributed positions and functioning individually are integrated into one key.

2 is an exploded cross-sectional view illustrating a structure of a conventional multi function key, FIG. 3A is a front view illustrating an embodiment of a conventional multi function key, FIG. 3B is a rear view of FIG. 3A, and FIG. 4 is a CC of FIG. 3A. Line cross section. Hereinafter, the structure of the multi function key of Korean Unexamined Utility Model Publication No. 2000-005501 will be described with reference to the drawings.

The key printed circuit board 40, the shield frame 50, and the main printed circuit board 60 are coupled to the lower side of the keypad 30. On the keypad 30, a rib 31 having a groove 31a formed in the center with both function keys 32 and 32 'interposed therebetween is provided upwardly, and between the function keys 32 and 32'. The multi-function key 10 is mounted on the keypad 30, but the multi-function key 10 has a plurality of pressing parts for pressing down certain portions of the multi-key 10 by pressing the fingers up, down, left, and right of the upper surface. , Frequently used function keys such as the "Menu" key, the "Search" key, the "Korean / English" and "Arrow" keys, the "Message" and the "Arrow" keys, respectively. The pressing surface which consists of the corresponding 1st press part 11a, the 2nd press part 11b, the 3rd press part 11c, and the 4th press part 11d is provided, and each said press part 11a- is provided. 11d), and the first, fourth, and fourth pressing protrusions 12, 12 ', 13, and 13' corresponding to the terminals of the key printed circuit board 40 are formed on the top, bottom, left, and right sides of the bottom surface. In the center between (12, 12 ', 13, 13') ) Is formed downward, and the position fixing groove 15 for fixing the key mounting portion of the mobile communication terminal to prevent the rotation of the multi-key is formed.

The front cover 20 is coupled to the upper side of the keypad 30, and the front cover 20 has a key exposure opening through which the function keys 32 and 32 'located at both sides of the keypad 30 pass through. 22, 22 ', and the key exposure port 21 through which the multi-function key 10 penetrates between the key exposure ports 22 and 22', and the pressing surface 11 of the multi-function key 10 is exposed to the outside. ) Is formed.

Meanwhile, recently released portable terminals have a separate center selection key formed at the center of the upper surface of the multi-function key (see 510 of FIG. 5). The structure of the center selection key is described in detail with reference to FIGS. 2 to 4. It is independent of the function key structure.

That is, a through hole through which the center selection key penetrates is formed at the center of the multi function key (see 10 in FIG. 2), and when the user presses the pressing surface 510 of the central selection key, the center facing the pressing surface 510 is formed. The end of the selection key is in direct contact with the contact portion on the key key printed circuit board 40 (not shown).

However, in manufacturing a conventional multi-function key having a separate center selection key, there is a problem that two parts (multi function key and center selection key) are needed instead of a single part (multi function key). There is a problem that a separate process for installing the key is required. In addition, since the multi-function key and the center selection key are not integrated, the overall appearance design is not simplified.

On the other hand, the characteristics of the antenna are important in the mobile terminal. In order to make use of the characteristics of the antenna, a wire antenna made of a shape memory alloy is generally installed in a portable terminal and used outside of it. Although the length of the antenna is slightly different depending on the telephone system such as PCS, GSM, CDMA, etc., the length of the antenna to be exposed should generally be about 60mm to 80mm, but the antenna's unique characteristics can be utilized.

Conventionally, in installing an antenna in a wristwatch-type portable terminal, in order to install only an internal antenna in the terminal body or to make use of the characteristics of the antenna, the antenna can be pulled out to a certain distance from the terminal body as in a conventional mobile phone. It was.

However, in the conventional method, a separate space for accommodating the antenna should be provided in the terminal body. As a result, there is a problem that the main body of the wristwatch-type portable terminal becomes relatively large. In addition, a separate mechanism for extracting or retracting the wire antenna from the main body should be provided in the terminal main body. Therefore, it is difficult to miniaturize and simplify the wristwatch-type portable terminal for product competitiveness.

On the other hand, currently packaged batteries are packaged with a battery cell, an overcharge / overcurrent protection circuit, a flexible printed circuit board, and a terminal block for connection to external terminals. Structure.

An overcharge / overcurrent protection circuit part in which a circuit that prevents the power supply from being directly charged by the positive / negative terminal of the battery cell itself is attached to the board. The device driving terminal connected directly to the positive / negative terminal of the battery cell itself And a pair of negative terminals) and a charging terminal (a pair of positive and negative terminals) for receiving power from an external charger. Power input from the charging terminal is input to the positive / negative terminal of the battery cell itself via the overcharge / overcurrent protection circuit.

The overcharge / overcurrent protection circuits on the market are divided into a COB (Chip on Board) type that is packaged with a mold and a PCM (Protection Circuit Module) type that is not packaged to protect a circuit attached to a substrate. Lose.

In the packaged battery, a terminal block for connecting to an external terminal includes a first terminal terminal (a pair of positive and negative terminals) connected directly to a driving terminal provided in an external device (eg, a mobile phone), and an external device. A second terminal terminal (a pair of positive and negative terminals) connected directly to a charging terminal provided in a charger (eg, a mobile phone charger) is provided.

In addition, the flexible printed circuit board in the packaged battery is to facilitate the operation of connecting the overcharge / overcurrent protection circuit unit and the terminal block. On the flexible printed circuit board, the first terminal terminal of the terminal block is connected with the device driving terminal of the overcharge / overcurrent protection circuit portion, and the second terminal terminal of the terminal block is connected to the charging terminal of the overcharge / overcurrent protection circuit portion.

On the other hand, the packaged battery as described above can be installed in the battery case (Case) inner space to be used externally, this type of packaged battery is commonly called a hard-pack (Hard-Pack), the case A packaged battery that is built in the terminal body without an electronic device is called a soft-pack.

6 is a view showing the structure of a conventional packaged battery. A method of assembling a conventional packaged battery will be described with reference to FIG. 6.

The battery cell 601 is provided with a positive terminal 603 and a negative terminal 605. In order to connect the overcharge / overcurrent protection circuit portion 607 to the battery cell 601, an instrument driving terminal 609 of the positive electrode and the negative electrode is connected to the positive terminal 603 and the negative electrode, respectively, using an intermediate medium such as a lead wire or a plate. Solder to the terminal 605.

When the soldering operation for connecting the overcharge / overcurrent protection circuit portion 607 to the battery cell 601 is completed, the overcharge / overcurrent protection circuit portion 607 and the terminal block 615 are connected on the flexible printed circuit board 613. The work is done. On the flexible printed circuit board 613, a pattern for connecting the corresponding terminals is formed. Accordingly, an operator performs soldering to connect the first terminal 617 of the terminal block 615 and the device driving terminal 609 of the overcharge / overcurrent protection circuit unit 607, and the second terminal of the terminal block 615. The terminal 619 is connected to the charging terminal 611 of the overcharge / overcurrent protection circuit portion 607. The double-sided tape is used to fix the connection of each part of the packaged battery.

On the other hand, the above-described package type battery manufacturing method is an example when the battery cell 601 is used as a lithium polymer battery. In the rectangular lithium battery, the surface of the battery except the positive terminal has a negative polarity.

Therefore, if the battery cell 601 is replaced with a rectangular lithium battery, the negative electrode terminal 605 of FIG. 6 becomes a surface having an arbitrary negative electrode rather than a specific position on the surface of the battery cell 601. In addition, an insulating tape is attached around the positive electrode terminal 603 before the soldering operation. As described above, since the surface of the battery cell 601 except for the positive electrode terminal 603 has a negative polarity, due to the carelessness of the operator during the soldering operation, the positive terminal of the circuit portion 607 is connected to the battery cell 601. This is due to the fact that when it meets the negative polarity of, it short-circuits and damages the cell and even there is a risk of fire or explosion.

As described above, in order to assemble a conventional packaged battery, a worker must solder, and there are risk factors such as damage, fire, and explosion of a cell. It also takes a lot of time to assemble. In addition, since a device such as a terminal block 615, a flexible printed circuit board 613, and the like is required, the size of the packaged battery increases, and the manufacturing cost increases. In addition, the assembly work is complicated, and a lot of people are required for the work. In addition, since the work is performed only by human work, product productivity is very low.
