  The mobile phone 1 is configured as a so-called foldable mobile phone, and has a transmitting case 3 and a receiving case 5 that are connected to each other so as to be opened and closed. In the closed state, the front surfaces 3a and 5a on the front side of the drawing case 3 and the receiving case 5 face each other. The transmitting housing 3 and the receiving housing 5 are formed in a thin and thin rectangular parallelepiped shape in the facing direction in the closed state, for example. The transmitter case 3 has a front surface 3a, a back surface 3b which is a back side surface of the front surface 3a, and an outer peripheral surface 3c which is an outer peripheral side of the front surface 3a and the back surface 3b.

  The transmitter case 3 is provided with, for example, a microphone for communication (not shown), a built-in antenna for communication (not shown), and an operation unit 7 for receiving user operations. The receiving case 5 is provided with, for example, a speaker for call (not shown) and a display unit 9 for displaying images and characters.

  FIG. 2 is an exploded perspective view showing the front case 11 and the rear case 13 constituting the transmission case 3.

  In addition to the front case 11 and the rear case 13, the transmitter case 3 is bonded to the rear case 13 and a battery lid that is attached to and detached from the rear case 13 for attaching and detaching the battery. It has a translucent member that constitutes the window of the imaging unit.

  The front case 11 constitutes the front surface 3 a side portion of the transmission case 3, and the rear case 13 constitutes the back surface 3 b side portion of the transmission case 3. The front case 11 and the rear case 13 are fixed to face each other. The front case 11 and the rear case 13 are fixed by, for example, a screw inserted into one of the front case 11 and the rear case 13 and screwed into the other. Various electronic components such as a circuit board 16 (see FIG. 5) are disposed between the front case 11 and the rear case 13. The front case 11 and the rear case 13 are formed of resin, for example.

  The front case 11 includes a facing surface portion 11a that faces the rear case 13, and a wall portion 11b that protrudes toward the rear case 13 at the outer peripheral portion of the facing surface portion 11a. The facing surface portion 11a is formed in, for example, a rectangular shape having a width approximately equal to that of the front surface 3a. However, a relatively large opening 11c for exposing the operation unit 7 to the outside of the transmitter housing 3 is formed in the facing surface portion 11a. The wall portion 11b extends along the outer periphery of the facing surface portion 11a and surrounds the facing surface portion 11a. The wall portion 11b surrounds substantially the entire circumference of the facing surface portion 11a. However, a notch 11d for exposing a connector (not shown) to the outside of the transmitter housing 3 is provided on a part of the wall portion 11b. A notch is formed.

  The rear case 13 has a facing surface portion 13a that faces the front case 11, and a wall portion 13b that protrudes toward the front case 11 at the outer peripheral portion of the facing surface portion 13a. The facing surface portion 13a is formed in, for example, a rectangular shape having approximately half the width of the back surface 3b. In addition, the remaining part of the back surface 3b is comprised by the battery lid not shown. The wall portion 13b extends along the outer periphery of the facing surface portion 13a and surrounds the facing surface portion 13a. The top surface of the wall portion 13b abuts against the top surface of the wall portion 11b and forms at least a part of the outer peripheral surface 3c together with the wall portion 11b. However, since the wall 13b has a small projection amount compared to the wall portion 11b of the front case 11 (for example, half or less of the projection amount of the wall portion 11b), the outer peripheral surface 3c of the transmitter case 3 is Half or more is comprised by the wall part 11b.

  The transmitter case 3 is provided with a terminal portion 15 in the vicinity of the outer peripheral surface 3c. The terminal unit 15 is for charging a battery (not shown) disposed in the transmitter case 3, for example. The terminal portion 15 has two projecting pieces 19 provided on the rear case 13 and a recess 21 provided on the wall 11b of the front case 11 and through which the two projecting pieces 19 are inserted.

  FIG. 3 is an enlarged view in the vicinity of the terminal portion 15 of FIG. 4 is an exploded perspective view of the vicinity of the projecting piece 19 in the terminal portion 15 as seen from the inside of the transmitter case 3 (from a viewpoint opposite to that in FIG. 3).

  The terminal unit 15 has a terminal 17 that is connected to an electronic component in the transmitter case 3 and exposed to the outside of the transmitter case 3. The terminal 17 is temporarily fixed to the projecting piece 19 during the assembly of the transmitter casing 3, and is held by the projecting piece 19 and the recess 21 after the assembly of the transmitter casing 3. The details of the terminal 17, the projecting piece 19, the recess 21, etc. are as follows.

  The terminal 17 is formed by subjecting one sheet metal to press working such as punching or bending. The terminal 17 is generally made up of a total of four flat plate-like portions including three surfaces of a rectangular parallelepiped and one surface extending outward of the rectangular parallelepiped. That is, the terminal 17 is continuous with the outer surface portion 23, the outer surface portion 23, the top surface portion 25 orthogonal to the outer surface portion 23, the inner surface portion 27 that is continuous with the top surface portion 25 and faces the outer surface portion 23, and the inner surface portion 27. And an extending portion 29 (FIG. 4) extending to the opposite side to the outer surface portion 23 side. The outer side surface portion 23, the top surface portion 25, and the inner side surface portion 27 constitute three surfaces of the above-mentioned rectangular parallelepiped, and the extending portion 29 constitutes one surface that extends outward.

  The outer side surface portion 23 is a portion that is exposed to the outside of the transmission housing 3 and contacts a terminal of another electronic device. The top surface portion 25 and the inner side surface portion 27 are portions that form, together with the outer surface portion 23, a section having a substantially U-shaped cross section for sandwiching the protruding piece 19 in order to attach the terminal 17 to the protruding piece 19. In the following, a portion formed by these three surfaces (23, 25, and 27) and having a rectangular cross section of three sides (a U-shape and a U-shape) may be referred to as a sandwiching portion 31. The planar shape of the outer side surface portion 23 and the inner side surface portion 27 is, for example, a rectangle. Moreover, the outer side surface part 23 and the inner side surface part 27 are formed in the same shape and size, for example.

  The extending portion 29 is a portion that is located on the inside of the housing and is connected to an electronic component inside the housing. The planar shape of the extending part 29 is, for example, a rectangle. A contact point 29 a (FIG. 4) that contacts the terminal of the electronic component is formed at the end of the extending part 29 opposite to the inner side surface part 27. The contact point 29a is formed by, for example, a protruding portion that protrudes toward the side where the clamping portion 31 protrudes with respect to the extending portion 29 (in the present embodiment, the front case 11 side).

  The two protruding pieces 19 are arranged away from each other along the outer peripheral portion of the facing surface portion 13a. Each protruding piece 19 protrudes from the facing surface portion 13 a of the rear case 13 toward the front case 11. For example, the projecting piece 19 is generally formed in a thin rectangular parallelepiped shape in which the outer surface 19a and the inner surface 19c are thin. Further, the protrusion 19 has, for example, a width between two side surfaces 19d on both sides of the outer side surface 19a and the inner side surface 19c as viewed in the protruding direction based on a protruding amount (height) from the root to the top surface 19b. Is also formed into a small narrow shape.

  The terminal 17 is attached to the projecting piece 19 by sandwiching the projecting piece 19 by the sandwiching portion 31. Specifically, the outer surface 23 covers the outer surface 19a, the top surface 25 covers the top surface 19b, and the inner surface 27 covers the inner surface 19c. Note that, in the protruding direction of the protruding piece 19, the size of the protruding piece 19 and the size of the clamping portion 31 are the same. In the width direction (direction from one side surface 19d to the other side surface 19d), the projecting piece 19 is larger than the sandwiching portion 31, and the side portions 19e on both sides of the projecting piece 19 project laterally from the sandwiching portion 31. Yes.

  On the inner side surface 19c of the projecting piece 19, a protrusion 33 (FIG. 4) extending in the projecting direction of the projecting piece 19 is formed. On the other hand, a slit 35 extending from the top surface portion 25 to the extending portion 29 is formed in the inner side surface portion 27 of the terminal 17. By fitting the protrusion 33 into the slit 35, the terminal 17 is prevented from falling off the protrusion piece 19.

  A rib 37 (FIG. 4) is formed on the facing surface portion 13 a of the rear case 13 so as to surround the protruding piece 19. When the terminal 17 is attached to the projecting piece 19, the extending portion 29 of the terminal 17 is accommodated in an area surrounded by the ribs 37. Thereby, the positional deviation of the extending portion 29 is suppressed, and the contact of the member that is not scheduled to contact with the extending portion 29 is suppressed.

  The two recesses 21 are arranged at an interval corresponding to the interval between the two projecting pieces 19 along the outer peripheral portion of the facing surface portion 11a. Each recessed part 21 is formed when a part of wall part 11b is located inside the other part of the wall part 11b. Note that a portion of the wall portion 11b that enters the inside to form the recess 21 may be referred to as a standing portion 39. The standing portion 39 is connected to other portions of the wall portion 11b. That is, the standing portion 39 is located inside the other portion of the wall portion 11b, but no notch is provided between the standing portion 39 and the other portion of the wall portion 11b. .

  The concave portion 21 is formed on the outer surface of the wall portion 11b. The concave portion 21 is formed such that the direction in which the outer surface of the wall portion 11b faces is concave, and the direction in which the top surface of the wall portion 11b faces is also concave. The concave portion 21 is formed in a size and shape into which the protruding piece 19 to which the terminal 17 is attached is inserted. That is, it is formed in a substantially rectangular parallelepiped shape, and the dimension of each side is substantially equal to the dimension of each side of the protruding piece 19 to which the terminal 17 is attached.

  When the front case 11 and the rear case 13 are fixed in a state where the terminal 17 is attached to the projecting piece 19, the projecting piece 19 to which the terminal 17 is attached is located in the recess 21. 19 and the recess 21 to be sandwiched and held. The outer surface portion 23 of the terminal 17 is exposed to the outside of the transmitter case 3 from an opening portion formed in the outer surface of the wall portion 11 b formed by forming the recess portion 21.

  In the recess 21, groove portions 41 extending in the protruding direction of the standing portion 39 are respectively formed on the two surfaces on both sides of the standing portion 39. The shape and size of the groove portion 41 are substantially the same as the shape and size of the side portion 19e of the protruding piece 19. When the protruding piece 19 is inserted into the recess 21, the side portion 19 e is guided by the groove portion 41.

  In the front case 11, an engagement portion 43 (FIG. 3) is formed between the two recesses 21 adjacent to the two recesses 21. The engaging portion 43 is, for example, a direction in which the columnar portion erected between the two standing portions 39 faces the outer surface of the wall portion 11b in a portion closer to the rear case 13 than the top surface of the wall portion 11b. Is formed to protrude. On the other hand, in the rear case 13, an engaged portion 45 (FIG. 4) is formed between the two projecting pieces 19 adjacent to the two projecting pieces 19. The engaged portion 45 is formed, for example, so as to protrude in the direction of the inner surface of the wall portion 13b on the base side of the wall portion 13b, and the engaging portion 43 enters between the facing surface portion 13a. A gap that can be When the front case 11 and the rear case 13 are assembled, the engaging portion 43 and the engaged portion 45 are engaged in the facing direction of the front case 11 and the rear case 13.

  FIG. 5 is a cross-sectional view in the vicinity of the terminal portion 15. However, FIG. 5 is conceptual, and details of structures such as the ridge 33 and the slit 35 are not shown.

  As described above, the terminal 17 is attached to the projecting piece 19 and is disposed in the recess 21 together with the projecting piece 19. Therefore, the outer side surface portion 23 of the terminal 17, the protruding piece 19, the inner side surface portion 27 of the terminal 17, and the standing portion 39 (a part of the wall portion 11 b) are stacked in this order from the outside of the transmission housing 3. In addition, it is preferable that these are contact | abutted and laminated | stacked. However, these may be laminated so that a minute gap is generated in part when there is no load so that they are brought into contact with each other when a load assumed in use of the mobile phone 1 is applied.

  Between the front case 11 and the rear case 13, a circuit board 16 made of, for example, a printed wiring board based on a hard resin is disposed as an electronic component. The contact point 29 a of the extending portion 29 of the terminal 17 is in contact with the internal terminal 51 mounted on the circuit board 16. The contact pressure is obtained, for example, by a restoring force in which the extending portion 29 tries to move toward the protruding side of the contact point 29a with respect to the sandwiching portion 31.

  As shown in FIGS. 3 and 5, the front case 11 has a rib 47 that protrudes from the facing surface portion 11 a to the rear case 13 side outside the outer surface portion 23 of the terminal 17 and covers a part of the outer surface portion 23. Yes. On the other hand, as shown in FIGS. 4 and 5, the rear case 13 has ribs 49 that protrude from the facing surface portion 13 a to the front case 11 side outside the outer surface portion 23 and cover a part of the outer surface portion 23. . The rib 47 may be captured as a part of the wall portion 11b. Similarly, the rib 49 may be grasped as a part of the wall portion 13b. Each of the rib 47 and the rib 49 constitutes a part of the outer peripheral surface 3c.

  According to the first embodiment described above, the mobile phone 1 includes the transmitter case 3 having the front case 11 and the rear case 13 facing each other, the circuit board 16 provided in the transmitter case 3, and the circuit. A terminal 17 is connected to the substrate 16 and exposed from the transmitter housing 3. The rear case 13 includes a facing surface portion 13a that faces the front case 11, and a projecting piece 19 that protrudes toward the front case 11 at the outer peripheral portion of the facing surface portion 13a. The front case 11 includes a facing surface portion 11a that faces the rear case 13, and a wall portion 11b that protrudes toward the rear case 13 at the outer peripheral portion of the facing surface portion 11a. The terminal 17 includes an outer surface portion 23 and an inner surface portion 27 that sandwich the protrusion 19 from the outer surface 19a and the inner surface 19c and cover the outer surface 19a and the inner surface 19c of the protrusion 19, respectively. Further, the terminal 17 has an extending portion 29 that extends from the inner side surface portion 27 to the inside of the transmitter housing 3 and contacts the circuit board 16. The projecting piece 19 is located outside the wall portion 11b, and the outer surface portion 23, the projecting piece 19, the inner side surface portion 27, and the wall portion 11b are stacked in this order from the outside of the transmitter case 3.

  Therefore, on the outer peripheral surface 3c of the transmission housing 3, the projecting piece 19 and the wall portion 11b are laminated in the vicinity of the terminal 17, so that the rigidity of the housing is improved. Further, the terminal 17 is not only sandwiched between the projecting piece 19 by the outer side surface portion 23 and the inner side surface portion 27, but is also fixed by the inner side surface portion 27 being sandwiched between the projecting piece 19 and the wall portion 11b. It is more securely fixed to the transmission housing 3. Due to the double structure of the projecting piece 19 and the wall portion 11b, waterproofness and dustproofness in the vicinity of the terminal are improved.

  The terminal 17 has a top surface portion 25 that covers the top surface 19 b of the projecting piece 19 and connects the outer surface portion 23 and the inner surface portion 27, and covers the projecting piece 19 from the top surface 19 b side of the projecting piece 19. The extending portion 29 extends from the inner side surface portion 27 to the inner side of the transmitter case 3 on the base side of the projecting piece 19 from the top surface of the wall portion 11b. Therefore, the terminal 17 can be easily attached. When the projecting piece 19 is fitted in the recess 21, the possibility that the terminal 17 is detached or twisted is also reduced. It is also possible to increase the width of the projecting piece 19.

  The protrusion located inside the inner side surface portion 27 is a wall portion 11b extending along the outer periphery of the opposing surface portion 11a, and the protrusion sandwiched between the outer surface portion 23 and the inner side surface portion 27 faces a part of the wall portion 11b. It is the protrusion 19 to be. Therefore, the above-described laminated structure can be realized by using the wall portion 11b constituting the outer peripheral surface 3c of the transmission housing 3, and the configuration is simplified. Moreover, the notch portion is not provided in the wall portion 11b for attaching the terminal 17, and the rigidity of the front case 11 against a load that bends the facing surface portion 11a is increased.

  Since the concave portion 21 in which the projecting piece 19 is accommodated is formed on the outer surface of the wall portion 11b, the mutual complementation in rigidity between the projecting piece 19 and the wall portion 11b is more reliably performed. That is, the laminated structure of the wall 11b and the projecting piece 19 is also realized in the direction along the wall 11b, and the rigidity is improved. Further, the projecting piece 19 does not protrude from the outer peripheral surface 3c of the transmitting case 3 and the design of the transmitting case 3 is improved.

  On both sides of the outer side surface 19a and the inner side surface 19c of the projecting piece 19 as seen in the projecting direction of the projecting piece 19, the projecting piece 19 is formed with a side portion 19e, and the concave portion 21 is provided with the side portion 19e. A groove portion 41 is formed to guide in the 19 projecting directions. Therefore, the protrusion 19 is reliably positioned in the direction orthogonal to the outer side surface 19a and the inner side surface 19c. Furthermore, the extended distance from the outside of the housing to the inside of the housing on the side surface 19d side of the projecting piece 19 is increased, and the dustproofness and waterproofness are improved.

  The guide part for guiding the projecting piece 19 is a groove part 41 extending in the projecting direction of the projecting piece 19, and the guided part guided by the guide part is from the outer side surface part 23 and the inner side surface part 27 of the terminal 17. It is the side part 19e which protruded to the side of the protrusion direction. Therefore, the ridge guided by the groove portion 41 is constituted by the combination of the protrusion piece 19 and the terminal 17, and it is not necessary to form a protrusion on the protrusion piece 19 itself. As a result, the shape of the protruding piece 19 is simplified.

  The rear case 13 has at least two protruding pieces 19 and an engaged portion 45 provided between the two protruding pieces 19 and adjacent to the two protruding pieces. The front case 11 has an engaging portion 43 that engages with the engaged portion 45 in the opposing direction of the rear case 13 and the front case 11. Therefore, the separation of the joint between the rear case 13 and the front case 11 in the vicinity of the terminal 17 is reliably suppressed, and consequently, the positional deviation and deformation of the terminal 17 and the contact failure caused by these are suppressed.

  The rear case 13 has a rib 49 that protrudes from the facing surface portion 13 a to the facing surface portion 11 a side outside the outer surface portion 23 of the terminal 17 and covers a part of the outer surface portion 23 of the terminal 17. The front case 11 has a rib 47 that protrudes from the opposing surface portion 11 a toward the opposing surface portion 13 a on the outer side of the outer surface portion 23 of the terminal 17 and covers a part of the outer surface portion 23 of the terminal 17. The outer surface portion 23 of the terminal 17 is exposed between the top surfaces of the rib 49 and the rib 47. Therefore, the outer side surface portion 23 is exposed from between the top surfaces of the rib 47 and the rib 49 while being prevented from projecting to the outside of the transmitting housing 3 by the rib 47 and the rib 49.

  A protrusion 33 extending in the protruding direction of the protruding piece 19 is formed on the inner side surface 19 c of the protruding piece 19, and a slit 35 that fits the protruding line 33 is formed on the inner side surface portion 27 of the terminal 17. . Therefore, dropping of the terminal 17 from the protruding piece 19 is suppressed. Furthermore, the moment of inertia of the section related to the bending of the axis of the protruding piece 19 in the protruding direction is improved, and the rigidity of the protruding piece 19 is improved.
