  The second hinge part (not shown) includes, for example, a member that fits into the hole on the sliding surface opposite to the side on which the first hinge part 44 is provided on the convex portion 9 and the hole on the sliding surface of the concave portion 10. And a member that is coupled to each other so as to be rotatable relative to each other, and includes a mechanism that generates a click feeling associated with opening and closing. The circuit board 29 of the transmitting housing 2 and the display substrate (not shown) of the receiving housing 3 are electrically connected by a cable 46. The cable 46 extends from the first mounting surface 29b of the circuit board 29 of the transmitter housing 2, is inserted through the first hinge part 44 and enters the convex portion 9, and is used for a display substrate and an imaging device inside the receiver housing 3. It has reached the substrate.

  The circuit board 29 is formed of, for example, a printed wiring board based on a resin, and includes a second mounting surface 29a on the front case 21 side and a first mounting surface 29b on the back side thereof. The second mounting surface 29a and the first mounting surface 29b are approximately the same area as the area obtained by subtracting the area of the connecting portion 4 from the area of the transmitter casing 2 when the transmitter casing 2 is viewed from the front. have. The circuit board 29 is positioned with respect to the transmitter case 2 in the direction along the mounting surface by contacting the inner side surface of the front case 21 or a screw boss for fixing the front case 21 and the rear case 22. Yes.

  A wiring pattern is formed on the second mounting surface 29 a and the first mounting surface 29 b of the circuit board 29, various electronic components 41 are provided, and an electronic circuit 42 is configured. For example, the circuit board 29 is provided with a communication processing unit (not shown), a control unit (not shown) for controlling the main display unit 7 and the like based on signals from the operation unit 6 and the like. Further, a ground pattern layer 43 is formed on the second mounting surface 29a and the first mounting surface 29b so as to divide each mounting surface into a plurality of regions, and electrostatic countermeasure parts such as the shield case 28 are electrically connected. Yes.

  Then, the power supply terminal 81 shown in FIG. 4 is mounted on the first mounting surface 29 b of the circuit board 29. The power supply terminal 81 has a main body 82 formed of an insulator such as resin, a plurality of contacts 83, and mounting legs (not shown). The mounting leg portion has a fixed pin and a plurality of conductive portions through which the plurality of contacts 83 are electrically connected, and the plurality of conductive portions can be connected to a necessary portion for supplying power to the pattern of the circuit board 29. Thus, the fixing pin is inserted through and fixed to the hole provided at the mounting location of the power supply terminal 81 on the first mounting surface 29b, and the conductive portion is soldered and fixed to the required location. That is, the power supply terminal 81 is mounted in a direction perpendicular to the first mounting surface 29 b of the circuit board 29.

  Each of the plurality of contact terminals 83 is provided so as to protrude from the main body 82 of the power supply terminal 81, and is formed of a cylindrical metal body having an elastic body such as a spring therein and buried in the protruding direction. Elasticity that can expand and contract in the direction is attached.

  The relationship between the contactor 83 and the battery housing part 22a will be described with reference to FIG. FIG. 6 is a diagram showing a part of a cross section taken along the line PP ′ in FIG.

  The rear case 22 that is a casing piece is formed with a battery storage chamber 22 provided on the side opposite to the plane B corresponding to the circuit board 29, that is, outside the casing, on the plane A and the bottom surface. The battery housing portion 22a is formed so as to surround the plane A with a side wall 22b.

  Now, as shown in FIG. 6, the protruding direction of the contactor 83 is a direction that is basically perpendicular to the mounting direction of the power supply terminal 81 and is substantially parallel to the plane A and the first mounting surface 29b. . A plurality of contacts 83 are provided in a direction orthogonal to the protruding direction and parallel to the plane A. When the battery 30 is housed in the battery housing chamber 22a of the rear case 22, the battery contacts 30a at one end of the battery 30 are first housed in the battery housing chamber 22a and brought into contact with the contactor 83, and then the contactor 83 is moved to the main body. The battery 30 is slid while being pressed against the end opposite to the end where the battery contact 30a is provided so as to be pressed in the direction in which it is buried in the battery 82. The protrusion direction from the main body 82 (that is, the burying direction) is provided in a direction parallel to the bottom surface (plane A) of the battery housing chamber 22a.

  Further, the plane A that forms the bottom surface and the plane B that is opposite to the plane A are both formed in parallel with the first mounting surface 29b, and the electronic components 41 having the same height are regularly arranged in the gap. Thus, the mobile phone 1 itself is configured to be downsized. That is, the protruding direction of the contactor 83 is also parallel to the first mounting surface 29b.

  In consideration of the housing operation of the battery 30, the direction in which the contact 83 protrudes is slightly offset from the direction parallel to the bottom surface (first mounting surface 29 b) of the battery housing chamber 22 a, so that the battery contact 30 a The battery 30 can be easily accommodated when the abutting tip portion is directed away from the bottom surface (first mounting surface 29b) of the battery accommodating chamber 22a. However, unless the contactor 83 protrudes from the main body 82 of the power supply terminal 81 (that is, can be buried) at least in a direction parallel to the bottom surface (first mounting surface 29b) of the battery housing chamber 22a. Since the contact pressure of the contactor 83 cannot be secured with a restoring force of the contactor 83 with respect to the battery contact 30a of the stored battery 30, the direction in which the contactor 83 protrudes generally corresponds to the bottom surface of the battery storage chamber 22a (second 1 in the direction parallel to the mounting surface 29b).

  In the case of the power supply terminal 81 having such a configuration, in order to attach the rear case 22 only by moving in a direction perpendicular to the circuit board 29, the battery housing is considered in consideration of interference of the contactor 83 with the rear case 22. It is necessary to form the opening 22c cut out from the end of the bottom surface of the portion 22a to a part of the side wall 22b. However, in this case, an opening having a size of at least the width M (the protruding amount of the contactor 83) in FIG. 6 remains in the region indicated by K1 in FIG. There remains a risk that foreign matter such as dust will enter.

  Further, considering the downsizing of the device, the lower part of the contactor 83, that is, the area facing the contactor 83 of the circuit board 29 is not effectively used, and there is a demand to arrange an electronic component here.

  Next, an example of a power supply terminal in which the configuration of the power supply terminal 81 is improved is shown in FIG. In addition, about the same location as the power supply terminal 81 on the structure, the same code | symbol is used and description is abbreviate | omitted. The mounting on the circuit board 29 is the same as that for the power supply terminal 81.

  The power supply terminal 811 has an extending portion 84 extending from the main body 82. The extending portion 84 is integrally formed continuously from the main body 82 on the circuit board 29 side (that is, the mounting base end side) with respect to the contact 83 in the mounting direction of the power supply terminal 811. The extending direction from the main body 82 is the same as the projecting direction of the contactor 83 or a direction parallel to the circuit board 29 and the plane A perpendicular to the mounting direction. A plane D is formed at a location facing the contact 83 of the extending portion 84.

  The plane D has a width in a direction orthogonal to the extending direction of the extending portion 84, particularly in a direction coinciding with the arrangement direction of the plurality of contacts 83, and this width can cover at least all the contacts 83. Has a length of Further, the extending length of the extending portion 84 (which is also the length of the plane D that coincides with the extending direction in this example) is at least longer than the protruding amount of the contactor 83 and corresponds to the side wall in the opening 22c. It is preferable that the length be within the length from the portion to be opened to the opening edge portion in the plane A, and that the tip of the extending portion 84 can be in contact with the edge of the opening portion 22c.

  FIGS. 8A and 8B are views showing a state in which the rear case 22 is attached to the circuit board 29 to which the power supply terminal 811 is attached. FIG. 9 is a view showing a straight QQ ′ cross section of the rear case 22 in FIG. As in the description of the power supply terminal 81, at least the length of the width M is cut out at the end of the plane A, and the power supply terminal 811 is also attached to the first mounting surface 29b in a part of the side wall 22b adjacent to the cutout. The opening 22c is formed by notching so as to be accommodated in the height direction with respect to and by continuing the notches. With this configuration, when the rear case 22 is assembled to the front case 21 to which the circuit board 29 is attached, the opening is not tilted (only in the vertical direction) without tilting the rear case 22 with respect to the first mounting surface 29b. The contact 83 can be attached to 22c without interference. And the surface in which the contactor 83 of the power supply terminal 811 is provided enters the part notched in the opening part 22c of the side wall 22b of the battery accommodating part 22a, and makes a part of side wall.

  In the opening 22c, the plane D forms a plane continuous with the plane A. That is, the extending portion 84 has a distance between the plane A and the first mounting surface 29b in the region between the contact 83 and the circuit board 29 in the mounting direction of the power terminal 81. Is formed on the surface on which the contactor 83 is provided so as to coincide with the distance between the contactor 83 and the contactor 83. Further, in the arrangement direction of the contacts 83 (in the illustrated example, the arrangement of the three contacts 83), the plane D has a width long enough to cover all the contacts 83, and the openings are open in the same direction as this width. The portion 22c is also formed with a width that is the same as or slightly larger than the width of the plane D, and the contactor 83 can penetrate the opening 22c in the vertical direction when the rear case 22 is attached. Further, the plane D and the plane A also form a continuous surface in the arrangement direction of the contacts 83.

  With such a configuration, the cellular phone 1 having the circuit board 29 on which the power supply terminal 811 is mounted has a notch in the plane A on the bottom surface of the battery accommodating portion 22a by the plane D in the region K2 shown in FIG. And the cutout of the side wall 22b can be closed by the main body 82 of the power supply terminal 811 itself (particularly the surface on which the contactor 83 is provided). That is, the opening portion 22c can be blocked by the power supply terminal 811 while facilitating the assembling process of the rear case 22, so that intrusion of dust and dirt can be prevented and the battery 30 is not accommodated. The circuit board 29 is not visible and the aesthetic appearance is not impaired.

  Further, since the opening 22c is closed after the rear case 22 is assembled as described above, the extending portion 84 is formed to have a predetermined gap with the circuit board 29 as shown in FIG. Even when a further electronic component X is disposed near the mounting portion of the main body 82 of the first mounting surface 29b using the gap portion, the electronic component X is visible and the aesthetic appearance is deteriorated, or the user touches the electronic component X. It is possible to prevent a situation such as being untidy. As described above, when the electronic component X is disposed in the gap between the extension portion 84 of the power supply terminal 811 of the circuit board 29 and the electronic component X is disposed on the circuit board 29, the procedure for attaching the power supply terminal 811 is performed. If it takes, the extending part 84 will not interfere and a mounting process will become easy.

  In addition, when the battery 30 is accommodated in the battery accommodating portion 22a, a continuous plane constituted by the plane A and the plane D in a region surrounded by the side wall 22b and the surface of the main body 82 of the power supply terminal 811 continuous to the side wall 22b. A battery 30 is arranged on the top.

  Next, an example of the power supply terminal 812 in which the configuration of the power supply terminal 811 is further improved is shown in FIG. In addition, about the location which overlaps with the power terminal 81 and the power terminal 811 on a structure, the same code | symbol is used and description is abbreviate | omitted. The power supply terminal 812 is also mounted on the circuit board 29 in the same manner as the power supply terminal 81.

  The power supply terminal 812 has an extending portion 84 that extends from the main body 82, similarly to the power supply terminal 811. The extending portion 84 has a stepped shape E as shown in the drawing in the extending direction tip. The step shape E is formed by making the extension amount longer than the plane portion D on the side opposite to the side where the plane D is provided in the extension portion 84 (that is, the side facing the first mounting surface 29b). Yes. The plane D has a width in a direction orthogonal to the extending direction of the extending portion 84, particularly in a direction coinciding with the arrangement direction of the plurality of contacts 83, as in the description of the power supply terminal 811. Has a length that can cover at least the entire contact 83. Also, the length of the plane D that coincides with the extending direction is also longer than the amount of protrusion of the contactor 83 and the opening edge in the plane A from the position corresponding to the side wall of the opening 22c, as in the case of the power supply terminal 811. It is preferable that the length is within the length up to the portion, and that the tip of the extension portion 84 can abut against the edge of the opening 22c.

  FIG. 11 is a diagram illustrating a state in which the rear case 22 is attached to the circuit board 29 to which the power supply terminal 812 is attached. The rear case 22 is notched at least at the length of the width M at the end of the plane A, and the power terminal 811 has a height relative to the first mounting surface 29b in a part of the side wall 22b adjacent to the notch. The opening 22c is formed by notching so as to be accommodated in the direction, and continuing the notches. Accordingly, as in the case of the power supply terminal 811, the contactor 83 interferes with the opening 22c without tilting the rear case 22 with respect to the first mounting surface 29b (only by moving in the vertical direction). Can be installed without.

  Then, the second stepped shape C is formed by cutting out the peripheral edge of the opening 22c at the end of the surface opposite to the plane A (that is, the side facing the first mounting surface 29b). When the power terminal 812 is incorporated in the opening of the rear case 22 when the rear case 22 is assembled to the front case 21 to which the circuit board 29 is attached, the second step shape C is the first step shape E described above. And the plane D forms a plane continuous with the plane A. Similarly to the case of the power supply terminal 811, the surface of the power supply terminal 812 on which the contact 83 is provided enters the portion cut out at the opening 22c of the side wall 22b of the battery housing portion 22a and part of the side wall. Make.

  With this configuration, the mobile phone 1 having the circuit board 29 on which the power supply terminal 812 is mounted not only blocks the cutout of the plane A on the bottom surface of the battery housing portion 22a with the plane D, but also has the first step shape E and the first shape. By meshing with the second step shape C, the gap between the battery housing chamber 22a and the inside of the housing can be refracted, which not only enhances dust and water resistance, but also is provided on the circuit board 29. Leakage of light by the light emitting member can be prevented. Further, the projecting portion of the first step shape E forming the meshing shape is aligned with the notch portion of the second step shape C, and the extending portion 84 is arranged on the inner side of the housing than the rear case 22. Therefore, the power terminal 812 does not interfere with the rear case 22 when it is attached.

  In the example of the power supply terminal 812, the first step shape E and the second step shape C are shown as examples provided only on one side of the substantially rectangular opening 22c and the extending portion. By providing it over the entire circumference of the extending portion 84, it is possible to further improve the dustproof and waterproof properties.

  If the first step shape E is formed, instead of providing the second step shape C, the thickness between the plane A and the plane B is formed thin, and when the power supply terminal 812 is attached, Even if the tip protruding portion of the first step shape E overlaps the plane B side in the opening 22c and the first step shape non-projecting tip portion is adjacent to the inner surface of the opening, the battery is accommodated. The same effect that the circuit board 29 is not exposed in the chamber 22a can be obtained.

  Similarly to the case of the power supply terminal 811, as shown in FIG. 11, the extension portion 84 is formed so as to have a predetermined gap between the circuit board 29 and the first gap portion is used. Even when a further electronic component X is disposed in the vicinity of the mounting location of the main body 82 of the mounting surface 29b, the opening 22c is closed after the rear case 22 is attached, so that the electronic component X can be seen from the opening 22c and is beautiful. It is also possible to prevent the user from touching the electronic component X. Regarding the mounting procedure, it is preferable to take the procedure of attaching the power supply terminal 812 after the electronic component X is arranged on the circuit board 29 as in the case of the power supply terminal 811.

  Finally, in the cellular phone 1 having the power terminal configured as described above, the battery 30 is inserted into the battery housing chamber 22a with one end having the battery contact 30a first and brought into contact with the contact 83, and the other end is pressed. When the battery 30 is entirely slid in the battery housing chamber 22a while being slid, the battery 30 is pressed in the direction of the other end by the urging force in the protruding direction by the elasticity of the contact 83, and between the side wall 22b. Thus, the battery 30 is fixed and is difficult to fall off.

  As described above, according to the configuration of the power supply terminal and the portable electronic device having the power terminal according to the present invention, it is possible to facilitate the process when the casing piece and the circuit board are assembled with each other.

  That is, according to the configuration of the present invention, by placing the rear case 23 in a direction perpendicular to the circuit board 29 while the circuit board is fixed to the front case 21 side, the contact of the power terminal does not interfere with the rear case 22. Can be attached. Specifically, when the circuit board 29 is incorporated in the housing (sending housing 3), the circuit board 29 is first assembled in one of the front case 21 and the rear case 22, and the other is attached. However, in the case of the configuration in which the contacts interfere with each other as in the prior art, the circuit board 29 must be built in the rear case 22 first, and according to the configuration of the present invention, either the front case 21 side or the rear case 22 side is required. Since the housing can be easily completed even if the circuit board 29 is assembled first, the circuit board is placed first on either the front case 21 side or the rear case 22 side for convenience of processes other than the mounting of the circuit board 29. It is also possible to create a degree of freedom in terms of design and process of whether or not to incorporate 29.

  In addition, while being advantageous in the assembly process as described above, it is possible to prevent the intrusion of foreign matters in the battery housing chamber, and to be possible without causing any harmful effects when mounting components near the power supply terminal on the circuit board. It is also possible to reduce the size.
