  However, in the portable electronic device disclosed in Patent Document 1, since the hinge needs to have a diameter that allows a cable with a connector or a flexible cable to pass through, the hinge itself becomes large, and the device main body becomes large accordingly. There was a problem of becoming.

  The present invention has been made in view of such circumstances, and is arranged in the upper housing without increasing the diameter of the hinge that rotatably connects the upper housing and the lower housing of the portable wireless device having a folding structure. It is an object of the present invention to provide a portable wireless device that can pass through a connection line that electrically connects a circuit board that is arranged and a circuit board disposed in a lower housing.

  The portable wireless device of the present invention includes a first casing, a second casing that is pivotably connected to the first casing, and a first that connects the first casing and the second casing. A hinge, a second hinge connecting the first casing and the second casing, a first circuit board provided in the first casing, and a second circuit provided in the second casing A portable wireless device comprising a board and a connection line that passes through the first hinge and connects the first circuit board and the second circuit board, wherein the first hinge is formed of a resin member and a conductor member. It is composed of two members, and the conductor member has a cylindrical shape having a notch, and is electrically connected via the first radio unit and the first power feeding unit arranged in the first casing or the second casing. The conductor member is electromagnetically coupled to the metal plate in the first casing or the second casing, and the resin member is Characterized in that it engages the notch of the serial conductor member.

  According to the above configuration, the first hinge is composed of two members, that is, the resin member and the conductor member, and the conductor member is provided with the notch portion, so that the connection line can be easily passed through the first hinge. Of course, even if the connector is connected to the connection line, it can be easily passed. Moreover, since the conductor member is electromagnetically coupled to the metal plate in the first housing or the second housing, it can also be used as an antenna. In addition, when the resin member of the first hinge is connected to the conductor member, it engages and closes the notch portion of the conductor member, so that the connection line can be prevented from being caught in the notch portion in the conductor member. The connection line is not broken.

  In the above configuration, when the first casing and the second casing are in a closed state, the notch portion of the conductor member is close to the metal plate in the second casing, and the first casing When the body and the second housing are in an open state, the cutout portion of the conductor member is separated from the metal plate in the second housing.

  According to the above configuration, the cutout portion of the conductor member of the first hinge is separated from the metal plate in the second housing by opening the first housing and the second housing, but the conductor portion is not cut. Since the portion excluding the notch portion is close to the metal plate in the second casing, electromagnetic coupling with the metal plate is increased, and the conductor member can be operated as an antenna. Note that one-seg reception is an example of an application that is used with the first housing and the second housing open. When the first hinge is used as a one-seg receiving antenna, the one-seg broadcast can be received with good sensitivity by opening the first and second housings.

  According to the present invention, the circuit board disposed in the upper casing and the lower casing are arranged without increasing the diameter of the hinge that rotatably connects the upper casing and the lower casing of the portable wireless device having the folding structure. A connection line for electrically connecting the arranged circuit boards can be passed. And since the diameter of a hinge is not enlarged, a portable radio apparatus does not enlarge.

A main liquid crystal unit 40 is disposed on the inner surface side of the upper housing 20, and a sub liquid crystal unit 41 is disposed on the outer surface side of the upper housing 20.

  FIG. 2 is a perspective view showing the surrounding structure including the hinge 30 of the portable wireless device 1. In particular, this figure is a view seen from the back side of the portable wireless device 1. In the figure, in the lower housing 10, a first circuit board 104 on which a first radio unit 101 and a first power feeding unit 103 are mounted, and a second circuit on which a second radio unit 107 and a second power feeding unit 106 are mounted. A board 108 and a camera 109 arranged in the concave portion 108a of the second circuit board 108 are arranged. The first circuit board 104 is formed in a substantially L shape, and the second circuit board 108 is formed in a substantially concave shape. The first circuit board 104 is stacked on the second circuit board 108.

  In the upper housing 20, a third circuit board 201 that electrically connects the main liquid crystal unit 40 and the sub liquid crystal unit 41 and an insert metal plate (metal plate) 202 for reinforcing the main liquid crystal unit 40 are arranged. ing. The insert sheet metal 202 is formed in a size that covers substantially the entire area of the upper housing 20 including the hinge 30. The second circuit board 108 arranged in the lower casing 10 and the third circuit board 201 arranged in the upper casing 20 are electrically connected by a thin coaxial cable (connection line) 50. The hinge 30 includes two members, a first hinge 31 and a second hinge 32. The first hinge 31 is on the left side in FIG. 2, and the second hinge 32 is on the right side in FIG. It arrange | positions so that it may space apart with respect to a body width direction. The first hinge 31 is used as, for example, an exciter of a one-segment dipole antenna, and is connected to the first radio unit 101 via the first power supply sheet metal 102 and the first power supply unit 103. The second hinge 32 is used, for example, as a cellular monopole antenna, and is connected to the second radio unit 107 via the second feeding sheet metal 105 and the second feeding unit 106. The second hinge 32 is composed of a conductor member. As described above, the first hinge 31 and the second hinge 32 are arranged so as to be separated from each other in the housing width direction, so that the dipole antenna using the first hinge 31 and the monopole using the second hinge 32 are arranged. Antenna isolation can be ensured, and antenna gain deterioration due to electromagnetic coupling between antennas can be reduced.

  In addition, the first power supply unit 103 that connects the first power supply sheet metal 102 and the first wireless unit 101 is the first power supply unit 103 that connects the first circuit board 104, the second power supply sheet metal 105 and the second wireless unit 107, and The antenna current that contributes to the radiation of the dipole antenna using the first hinge 31 is applied to the first circuit board 104 and the second hinge 32 is provided by providing a power feeding unit on a different circuit board such as the second circuit board 108. The antenna current that contributes to the radiation of the monopole antenna flows mainly to the second circuit board 108 and to a different board. As a result, the isolation between the antennas is improved, and the amount of deterioration of the antenna gain due to electromagnetic coupling between the antennas is further reduced.

  FIG. 3 is a perspective view showing a general configuration of the thin coaxial cable 50 and the first hinge 31 as viewed from above. FIG. 4 is a perspective view showing a general configuration of the thin coaxial cable 50 and the first hinge 31 as viewed from below. 3 and 4, the first hinge 31 is composed of two members: a resin member 310 formed using a resin and a conductor member 311 formed using a metal. The conductor member 311 is formed in a cylindrical shape having a notch 311a, and is electrically connected via the first radio unit 101, the first power supply sheet metal 102, and the first power supply unit 103 disposed in the lower housing 10. Connected to. The diameter of the conductor member 311 is large enough to pass the thin coaxial cable 50. The resin member 310 is formed in a size and shape that can accommodate the conductor member 311, and has a protrusion 310 a that engages with the notch 311 a of the conductor member 311. The resin member 310 and the conductor member 311 are integrated by inserting a part of the conductor member 311 into the resin member 310.

  A connector 60 for connecting to the third circuit board 201 in the upper housing 20 is connected to one end of the thin coaxial cable 50 and connected to the second circuit board 108 in the lower housing 10 at the other end. For this purpose, a connector 61 is connected. By forming the notch 311 a in the conductor member 311 of the first hinge 31, the thin coaxial cable 50 can be passed through the first hinge 31 with the connector 61 connected to the other end of the fine coaxial cable 50. Thus, by forming the notch 311a in the conductor member 311 of the first hinge 31, the connector 61 is connected to the thin coaxial cable 50 without increasing the diameter of the first hinge 31, so that the fine coaxial The cable 50 can be easily passed through the first hinge 31.

  By forming the projection 310 a that engages with the notch 311 a of the conductor member 311 on the resin member 310 of the first hinge 31, the thin coaxial cable 50 is connected to the notch 311 a of the conductor member 311 within the first hinge 31. Don't get caught. Thereby, the thin coaxial cable 50 is not disconnected in the first hinge 31.

  Since the conductor member 311 of the first hinge 31 is located near the insert metal plate 202 in the upper housing 20, it is electromagnetically coupled to the insert metal plate 202 and performs a dipole operation. The direction of the notch 311a of the conductor member 311 is set so that the electromagnetic coupling between the conductor member 311 of the first hinge 31 and the insert metal plate 202 becomes large when the lower housing 10 and the upper housing 20 are opened. It prescribes.

  5A and 5B are cross-sectional views showing the first hinge 31 and its peripheral portion, in which FIG. 5A shows a state where the lower housing 10 and the upper housing 20 are closed, and FIG. 5B shows a lower housing 10 and the upper housing 20. Is open. In FIG. 5, a hinge cover 70 is fixed to the first hinge 31 portion of the upper housing 20 with a double-sided tape 71. As shown in FIG. 5A, when the lower housing 10 and the upper housing 20 are in a closed state, the notch 311a of the conductor member 311 of the first hinge 31 is substantially opposed to the insert metal plate 202. The area where the conductor member 311 and the insert metal plate 202 overlap is reduced by the amount of the notch 311a. At this time, the amount of electromagnetic coupling between the conductor member 311 and the insert metal plate 202 is smaller than when the notch 311 a does not face the insert metal plate 202. On the other hand, as shown in FIG. 5B, when the lower housing 10 and the upper housing 20 are in the open state, the notch 311 a of the conductor member 311 of the first hinge 31 does not face the insert metal plate 202. Therefore, the area where the conductor member 311 and the insert sheet metal 202 overlap is increased, and the amount of electromagnetic coupling between the conductor member 311 and the insert sheet metal 202 is larger than in the above case. Thus, by defining the orientation of the notch 311a of the conductor member 311, the conductor member 311 can sufficiently act as an antenna when the lower housing 10 and the upper housing 20 are open. As described above, since the first hinge 31 is used as an exciter for the one-segment dipole antenna, the lower casing 10 and the upper casing 20 are opened when watching one-segment broadcasting. It is desirable to define the direction of the notch 311a as described above.

  As described above, according to the portable wireless device 1 of the present embodiment, the first hinge 31 that connects the lower housing 10 and the upper housing 20 is constituted by the two members of the resin member 310 and the conductor member 311, and the conductor Since the notch 311a is provided in the member 311, the thin coaxial cable 50 connecting the first circuit board 104 and the third circuit board 201 can be easily passed through the first hinge 31 even when the connector 61 is connected. it can. Moreover, since the conductor member 311 is electromagnetically coupled to the insert metal plate 202 in the upper housing 20, the first hinge 31 can be used as an antenna. Further, since the protrusion 310 a that engages with the notch 311 a of the conductor member 311 is provided on the resin member 310 of the first hinge 31, the protrusion 310 a is cut off of the conductor member 311 when connected to the conductor member 311. Since the notch 311a is closed, the thin coaxial cable 50 can be prevented from being caught by the notch 311a in the conductor member 311, and the fine coaxial cable 50 is not disconnected.

  In addition, according to the portable wireless device 1 of the present embodiment, the cutout portion 311a of the conductor member 311 of the first hinge 31 is formed in the upper casing by opening the lower casing 10 and the upper casing 20. Since the portion excluding the notch portion 311a is close to the insert sheet metal 202 in the upper housing 20, the electromagnetic coupling amount between the conductor member 311 and the insert sheet metal 202 can be increased. The member 311 can be operated as an antenna for receiving one segment. As a result, it is possible to receive the one-segment broadcasting with good sensitivity in a state where the lower housing 10 and the upper housing 20 are opened.

  In the portable wireless device 1 according to the present embodiment, the first circuit board 104 and the second circuit board 108 are arranged in the lower housing 10 and the third circuit board 201 is arranged in the upper housing 20. The reverse is also acceptable. That is, the first circuit board 104 and the second circuit board 108 may be arranged in the upper casing 20, and the third circuit board 201 may be arranged in the lower casing 10.

  In addition, the portable wireless device 1 of the present embodiment has a structure in which the upper housing 20 is rotatably connected to the lower housing 10 and can only be opened and closed. A swivel structure in which the upper housing is pivotably connected and the upper housing can be rotated 180 degrees in the horizontal direction, or a double that can be folded in the vertical and horizontal directions. Of course, it can be applied to an open structure.

  The present invention provides a circuit board disposed in an upper casing and a lower casing without increasing the diameter of a hinge that rotatably connects the upper casing and the lower casing of the portable wireless device having a folding structure. Therefore, it is possible to pass through a connection line for electrically connecting the circuit board, and it can be applied to a portable wireless device such as a cellular phone having a folding structure.
