Description

  The present invention relates to a portable electronic device driven by a battery.

  A portable electronic device incorporating a secondary battery, such as a mobile phone or PDA (Personal Digital Assistants), has a battery terminal for taking out the energy of the secondary battery and a charging terminal for injecting energy. And a charging terminal is often provided in the edge part of these portable electronic devices. In addition, to ensure safety, the charging terminal exposed to the device casing must have a sufficient +/- distance, or in order to improve reliability, charging can be performed in an incorrect combination using a dedicated charging stand. In order to prevent charging, the position and shape of the charging terminal or the shape of the housing are devised, and charging is performed only in an appropriate combination.

Further, as the size and thickness are reduced and the design is diversified, for example, as shown in FIG. 9, a case piece in which charging terminals 300 a and 300 b and a battery terminal 300 c constitute a part of the case. A technique is known in which the number of components is reduced by integrating with an input / output connector 300 mounted on an end portion of 100 to save space on a board (see, for example, Patent Documents 1 and 2). .
JP 2001-268812 A JP-A-11-111399

On the other hand, in a portable electronic device incorporating an antenna, it is required to provide the antenna at the end of the device in order to maintain good reception sensitivity. Therefore, since the end of the casing is occupied by the antenna, it is difficult to provide the above-described charging terminal at the end of the portable electronic device.
For this reason, as shown in FIG. 10, a structure in which the charging terminals 300a and 300b are exposed to the outside of the device casing, particularly on the surface other than the end portion, is conceivable. Specifically, the charging terminals 300a and 300b are arranged in the vicinity of the center of the substrate 30 and are exposed near the center of the top surface (or bottom surface) of the casing piece 100 that covers the substrate 30 in the portable device.
11 (a), 11 (b), and 11 (c) show the same battery as that seen from the top surface when the battery terminal 5000 is mounted on the substrate 30 and the surface in contact with the substrate 30 is assumed to be the bottom surface. The figure which showed the figure which caught the power supply terminal which mentions the terminal 5000 to the front, and the figure caught from the side view, and is fixed on the board | substrate 30 with the anchor 501 which consists of metal plates.
The battery terminal 5000 includes a + − power supply terminal (5010a, 5010b) and one signal terminal (501c).
The power terminals (5010a, 5010b) and the signal terminal 5010c pass through the battery terminal 5000.
The battery terminal 5000 is mounted on the substrate 30 on which the pattern is drawn.
Battery terminal 5000 is electrically connected to the pattern drawn on substrate 30. In order to be electrically connected to the pattern on the substrate 30, the battery terminal 5000 has substrate connection terminals 30a, 30b, and 30c at locations where the pattern of the substrate 30 is disposed.
The power supply terminals (5010a, 5010b) and the signal terminal 5010c are electrically connected to the board connection terminals 30a, 30b, 30c that are electrically connected on the surface of the battery terminal where the board 30 is mounted, and inside the battery terminal. It is connected.
The pattern disposed on the substrate 30 is further electrically connected to electronic components mounted on the substrate.
Therefore, the battery terminal can supply the electric power of the battery 60 to the electronic component mounted on the substrate.
Since the above-described structure can be laid out relatively freely as long as it is on the substrate 30, it is easy to meet the downsizing, thinning, and design diversity of portable electronic devices while ensuring the safety and reliability described above.
On the other hand, as a circuit portion (charging path) constituting an energy injection path to the battery 60, the charging terminals 300a and 300b are arranged in the vicinity of the battery terminal 5000 to minimize the line impedance in terms of electric circuit design or printing. It is preferable in the board design. However, the charging terminals 300a and 300b cannot always be arranged close to the battery terminal 500 due to the above-described miniaturization and design diversity that ensure safety and reliability. In this case, the line impedance is minimized. It cannot be made.
Moreover, the commercial power source supplied from the outside of the portable electronic device easily gives noise to the electronic components in the portable electronic device. If this commercial power supply noise passes through the substrate 30, the noise may propagate to nearby wiring and cause malfunction or failure. When the wiring of the charging path is extended, the noise consideration becomes widespread, which becomes a restriction on the electric circuit design or the printed circuit board design.

  Moreover, the charging terminal exposed to the outside shown in Patent Document 1 is configured to be connected to the battery via a conductive substance. Therefore, when the battery is charged with electric power, a potential difference occurs between the charging terminals that are exposed to the outside, which may cause a short circuit between the charging terminals due to contact of a conductive substance or the like. .

  The present invention has been made in order to solve the above-described problems, and while ensuring safety and reliability, it can cope with downsizing, thinning, or a variety of designs. It is an object of the present invention to provide a portable electronic device that can satisfy the design requirements of an electric circuit and a substrate that are optimal as a charging path by reducing the number of the electronic devices.

  In order to solve the above problems, a portable electronic device according to the present invention includes a battery that can be charged, a battery terminal that is electrically connected to the battery, and a charging circuit that controls charging of the battery. A substrate to be mounted; and a housing that covers the substrate and the battery, wherein the battery terminal covers a conductive member that electrically connects the battery and the charging circuit, and covers the periphery of the conductive member.

Example 1
FIGS. 5A, 5 </ b> B, 5 </ b> C, and 6 are views for explaining the battery terminal 500 according to the first embodiment of the present invention and the mounting structure of the portable electronic device. FIG. 5A shows a state where the battery terminal 500 is viewed from above when the substrate 30 on which the battery terminal 500 is mounted is turned down. FIG. 5B shows a state when the battery terminal 500 is viewed from the battery 60 side. Further, FIG. 5C shows a state when the battery terminal 500 is viewed from the direction shown in FIG. 5A and the direction orthogonal to both the directions shown in FIG. 5B. FIG. Characteristically, as shown in FIGS. 5 (a) and 5 (b), a fixing reinforcing metal portion (contact portion in claims) for fixing the battery terminal 500 to the substrate 30 (hereinafter referred to as an anchor 501). ) Is divided into two (501a, 501b). For example, the top plate 501a is used as a positive electrode on the substrate 30 and the top plate 501b is used as a negative contact terminal for charging.
As shown in the figure, the battery terminal 500 includes + (positive electrode) and − (negative electrode) conductive power supply terminals 500a and 500b, and a ground terminal 500c having conductivity, and the power supply terminal 500a, The power supply terminal 500b and the signal terminal 500c pass through the battery terminal 500 and make electrical contact with the board connection terminals 30a, 30b, and 30c provided on the back surface of the battery terminal 500, respectively, and the board connection terminals 30a, 30b, and 30c are connected to each other. And is electrically connected to an electronic component mounted on the substrate 30 to supply power to the battery 60. This mechanism is the same as the battery terminal 5000 in the prior art.

  Further, as shown in FIGS. 3B and 6, the charging terminal portion is fixed to the lid 70 of the device housing (sending housing 3). That is, the charging terminals 701a and 701b are exposed at positions sufficiently separated from each other on the outer surface of the lid 70 of the device housing in consideration of safety. Further, the metal plates 701c and 701d for guiding the charging terminals 701a and 701b to the mounting position of the battery terminal 500 along the inner wall are fixed to the inner surface of the lid 70. The sheet metals 701c and 701d are formed of a linear metal plate, and the charging terminals 701a and 701b are connected to each other at one end. In addition, spring contacts (elastic members) 702c and 702d are connected to the end portions of the metal plates 701c and 701d opposite to the portions in contact with the charging terminals 701a and 701b. The spring contacts 702c and 702d are respectively joined to the top plates 501a and 501b (contact portions) of the anchors 501 for fixing the battery terminals 500 with appropriate spring pressures. A contact portion 702 is provided. The contact portion is connected to the charge control unit 45 through a pattern arranged on the substrate 30. And a contact part is connected to board | substrate connection terminal 30a, 30b, 30c through a charge control part in between.

According to the first embodiment described above, the anchor mounting area 501 for fixing the battery terminal 500 on the substrate 30 is divided into two as contact terminal portions and used as charging terminals on the substrate 30, so that the component mounting area on the substrate 30 is In this case, a dedicated charging terminal that is conventionally mounted on the substrate 30 can be made unnecessary.
In addition, the mounting position of the charging terminal can be easily set to any position by simply changing the shape of the sheet metal as long as it is on the back of the device housing (sending housing 3). It can flexibly meet various design requirements.

  Furthermore, the charging path can easily minimize wiring, and thus a good electric circuit board is realized. Moreover, since the charging current supplied from the outside of the portable electronic device can shorten the distance through the circuit board as much as possible, the electronic components arranged on the substrate 30 are less susceptible to the noise of the commercial power supply, and the portable electronic device originally has It becomes easy to maintain performance.

Further, in a state where the charger is not connected, the conductor portion connecting the anchor 501 and the battery terminal 500 is in a high impedance state. A metal in a high impedance state is generally affected by electromagnetic wave noise from the outside. And the metal which received the influence of electromagnetic noise radiates | emits electromagnetic noise to the circumference | surroundings.
As in the prior art, when two charging terminals and a charging control unit exist on the board, two conductive wire portions arranged between the charging terminal and the charging control unit are arranged on the board. When these two conducting wires extend from the charging control unit, the two conducting wires are arranged in parallel on the substrate, and are branched and extended halfway toward the two charging terminals located at separate positions.
On the other hand, in this invention, the conducting wire on the board | substrate 30 which connects the charge control part 45 and the anchor 501 is distribute | arranged between the charge control part 45 and the anchor 501. FIG. Since the number of the battery terminals 500 having the anchors 501 is one, the two conductive wires extending from the charge control unit 45 are connected to the battery terminals 500 in a state of being aligned in parallel.
Therefore, the occupied area occupied on the substrate by the conductor portion arranged on the substrate in the present invention is less branched than the occupied area occupied on the substrate by the conductor portion arranged on the substrate 30 in the prior art. It gets smaller by the minute.
Therefore, since the number of electronic components arranged closer to the conductive wire portion in the present invention is smaller, the number of components affected by electromagnetic noise from the conductive wire portion among the electronic components arranged on the substrate is larger than the conventional one. Less. Similarly, since there is no branch in the state where the charger is connected, the area can be reduced and the influence of noise of the commercial power supply can be made difficult.

Similarly, the sheet metal 802 and 803 has charging terminals 802a and 803a at one end and a spring contact at the other end. 802b and 803b are integrally formed.
The lid 71 is provided with three openings, and the metal plates 801, 802, and 803 are attached to the inside of the lid 71 so that the power supply terminals 801a, 802a, and 803a are exposed from these openings. The spring contacts 801 b, 802 b, and 803 b protrude with elasticity in the direction from the inner surface of the lid 71 toward the substrate 30. When the lid 71 covers the substrate 30, the spring contacts 801 b, 802 b, and 803 b Each of the three contact terminals (507a, 507b, 507c) comes into contact with each other as shown in FIG.

  Accordingly, the power supply terminals 801a, 802a, and 803a are electrically connected to the first anchor, the second anchor, and the third anchor, respectively. Further, each of the first anchor and the second anchor is connected to the board connection terminals 30a and 30b. The board connection terminals 30 a and 30 b are connected to the charge control unit 45 through a pattern drawn on the board 30. Further, the third anchor is connected to a signal processing circuit (not shown), and an output signal from the mobile phone 1 can be output to the outside of the casing through the power supply terminal 803a. Based on the difference between the signal output from this terminal and the reference potential, for example, driving control of an external speaker provided as an additional function in the charging stand can be performed.

As described above, in the first embodiment of the present invention, a plurality of contact terminals are formed on the top surface of the battery terminal, and these contact terminals and an anchor for mounting and fixing the battery terminal are formed of an integral metal. did.
