  As shown in FIG. 2, the hinge unit 40 includes a unit main body 400 having a large diameter portion 402 and a small diameter portion 401 extending coaxially from the large diameter portion 402 and having a through hole 403 as a center. A conductive shaft portion 405 inserted through 403 and having a contact point 406 at an end thereof, and a conductive member 409 having a contact point 404 sandwiched integrally between the conductive shaft portion 405 and the unit main body 400 are mainly configured.

  The unit main body 400 has a substantially octagonal columnar large-diameter portion 402 and a small-diameter portion 401 that extends coaxially from the large-diameter portion 402 and extends substantially coaxially, and has a through-hole 403 that penetrates in the axial direction.

  The conductive shaft portion 405 is formed of an end portion 407 on the disc and a rod-like portion 408 extending perpendicularly from the center of the end portion 407. The tip of the rod-shaped portion 408 functions as a contact 406 that is electrically connected to a first contact member 50 described later. The contact 406 is electrically connected to a circuit board built in the second housing 30 via a first contact member 50 described later.

  The conductive member 409 is formed in a U-shaped cross section, and a through hole 410 is formed at the center. The conductive member 409 is fitted to one surface of the large-diameter portion 402 of the unit main body 400 and one surface facing the one surface, and the rod-shaped portion 408 is sandwiched between the conductive shaft portions 405 in a state where the through-hole 410 is inserted. In this way, the unit main body 400, the conductive shaft portion 405, and the conductive member 409 are assembled together and electrically connected to the conductive shaft portion 405 and the conductive member 409. The part exposed to the outer periphery of the large diameter portion 402 of the conductive member 409 functions as a contact 404 that is electrically connected to a second contact member 60 described later. The contact 404 is electrically connected to a circuit board built in the first housing 20 via a second contact member 60 described later.

As shown in FIG. 4, the portion protruding from the connection portion 220 of the small diameter portion 401 fits into the through hole 302 of the connection portion 300.

  The first contact member 50 is formed of a conductive plate material, has elasticity, and has a function of electrically connecting the circuit board of the second housing 30 and the hinge unit 40. As shown in FIG. 6, the first contact member 50 includes a contact contact portion (one end portion) 500 that contacts the contact 406 of the hinge unit 40, and continuously extends from both ends of the contact contact portion 500 so as to be substantially vertical. It is formed of two bent hinge connection pieces (one end portion) 502 and a second housing connection piece 506 extending from the central piece side of the contact contact portion 500 in a direction substantially parallel to the contact contact portion 500. The

  A curved portion (part) 504 that extends in the width direction and curves toward the side from which the hinge connection piece 502 extends is formed on the two contact portions 502 side of the contact contact portion 500. When the first contact member 50 is assembled to the small-diameter portion 401 of the hinge unit 40, the curved portion 504 is applied while the contact 406 protruding from the end surface of the small-diameter portion 401 and the contact abutting portion 500 have elasticity. A suitable distance from the end surface of the small diameter portion 406 for contact is formed. Further, the bending portion 504 is deformed by the contact between the contact 406 and the contact contact portion 500, and the contact between the contact 406 and the contact contact portion 500 is maintained by the elastic force due to the deformation.

  The two pieces of hinge connection pieces 502 are formed substantially in parallel with an interval of substantially the same width as the circumferential surface width of the small diameter portion 401 of the hinge unit 40. That is, the contact abutment portion 500 and the two pieces of the hinge connection piece 502 are formed in a substantially U-shaped cross section, and the two pieces of the hinge connection piece 502 sandwich the small diameter portion 401 of the hinge unit 40, thereby The one contact member 50 and the hinge unit 40 are fixed. Further, the two hinge connecting pieces 502 can be elastically deformed so that the end portions of the hinge connecting pieces 502 are close to each other by forming the curved portion 504. Further, the edge 503 of the two pieces of hinge connection piece 502 is bent substantially vertically outward from the other part of the hinge connection piece 502. The end edge 503 is engaged with the edge of the through hole 302 of the connection portion 300 when the first contact member 50 is assembled to the second housing 30.

  The second housing connection piece 506 is the first in the direction substantially parallel to the contact contact portion 500 from the central one side of the contact contact portion 500, that is, in a state where the first contact member 50 is assembled to the second housing 30. It protrudes from the contact point contact portion 500 in the direction extending to the housing 20 side.

  The second contact member 60 is formed of a conductive plate material, has elasticity, and has a function of electrically connecting the circuit board of the first housing 20 and the hinge unit 40. As shown in FIG. 5, the second contact member 60 includes a disc 600 formed with a through-hole 601 at the center, two pieces of hinge connection pieces (one end) 602, a guide piece 604, and a first housing connection piece. 606.

  The disc 600 is divided into eight parts with a predetermined width corresponding to the substantially octagonal columnar large-diameter portion 402 of the hinge unit 40. The two pieces of hinge connection pieces 602 are formed so as to extend substantially perpendicularly from the disc 600 from the opposing portions of the disc 600. The hinge connection piece 602 has a curved portion 603 that curves inward in the radial direction of the disc 600. When the second contact member 60 is assembled to the large-diameter portion 402 of the hinge unit 40, the curved portion 603 contacts the contact 404 of the conductive member 409 that is integrally assembled to the large-diameter portion 402. Electrically connected. The first housing connecting piece 606 and the guide piece 604 are arranged on the disc 600 so as to be opposed to each other at intervals from the two hinge connecting pieces 602. The guide piece 604 is formed so as to extend substantially vertically from the disc 600. The first housing connecting piece 606 extends substantially perpendicularly from the disc 600, bends at a predetermined length at a right angle toward the inner diameter direction of the disc 600, and further has a predetermined length and a large diameter of the disc 600. It is formed by bending at right angles to the direction. Here, the extending direction of the end portion of the first housing connection piece 606 is a direction toward the inside of the first housing 20 in a state where the second contact member 60 is assembled to the mobile phone 10. In the second contact member 60 shown in FIG. 5, the first connection piece 606 is bent at a right angle toward the inner diameter direction of the disc 600 for easy understanding. Strictly speaking, it is bent after being attached to the hinge unit 40.

  Next, the assembly state and function of the hinge unit 40, the first contact member 50, and the second contact member 60 configured as described above will be described.

  First, as shown in FIGS. 2 and 4, the first contact member 50 is attached to the second housing 30 so that the end edge 503 of the first contact member 50 is locked to the edge of the through hole 302 of the connection portion 300. Install. At this time, since the hinge connecting piece 502 of the first contact member 50 is easily elastically deformed by the curved portion 504, the attachment can be easily performed. Further, the first contact member 50 is positioned at a position suitable for contacting the contact 406 of the hinge unit 40 to be attached later by the end edge 503 being engaged with the edge of the through hole 302 of the connection portion 300. The

  The hinge unit 40 and the second contact member 60 are assembled by passing the through hole 601 of the second contact member 60 from the hinge connection piece 602 side to the small diameter portion 401 side of the hinge unit 40. When the disc 600 is brought into contact with the stepped portion of the large diameter portion 402 and the small diameter portion 401, it is assembled at a predetermined position. Further, in a state where the hinge unit 40 and the second contact member 60 are assembled, the bending portion 603 comes into contact with the contact 404 and becomes conductive with each other. After the hinge unit 40 and the second contact member 60 are assembled, the first housing connection piece 606 of the second contact member 60 is bent at a right angle toward the inner diameter direction of the disc 600. By doing in this way, it becomes a suitable position for inserting the 1st housing | casing connection piece 606 in the inside of the 1st housing | casing 20 attached later.

  Next, the first through hole 228, the second through hole 226, and the second through hole 302 are positioned coaxially so that the connection portions 220 and 222 of the first housing 20 and the connection portion 300 of the second housing 30 overlap each other. One housing 20 and a second housing 30 are arranged. Next, the hinge unit 40 assembled with the second contact member 60 is inserted into the hole 224 of the connection part 220 of the first housing 20 from the small diameter part 401 side. The hinge unit 40 is inserted to a position where the disc 600 contacts the stepped portion 225 formed in the through hole 228 and the hole 224 of the connecting portion 220. That is, the second contact member 60 is fixed to the first housing 20 and the hinge unit 40 by the disc 600 being sandwiched between the step portion 225 and the large diameter portion 402.

  In this state, the small-diameter portion 401 is inserted into the first contact member 50 fitted in the connection portion 300 of the second housing 30. In this state, the contact 406 is in contact with the contact abutting portion 500 while being pushed up. That is, the first contact member 50 is elastically deformed in the direction in which the first contact member 50 abuts on the contact 406 by the curved portion 504, and the connection between the contact 406 and the contact abutment portion 500 is firmly held. The first contact member 50 is fixed to the second housing 30 and the hinge unit 40 by sandwiching the two hinge connection pieces 502 between the connection part 300 and the small diameter part 401.

  As described above, the second contact member 60 is firmly fixed by being sandwiched between the first housing 20 and the hinge unit 40, and the first contact member 50 is connected to the second housing 30 and the hinge unit 40. And is firmly fixed by being sandwiched between them. Further, since the second contact member 60 is locked to the surface of the large diameter portion 402 continuous with the small diameter portion 401 of the hinge unit 40, the second contact member 60 does not come off from the hinge unit 40 in the axial direction. Similarly, since the end edge 503 of the hinge connection piece 502 is locked to the edge of the through hole 302 of the connection portion 300, the first contact member 50 does not come off from the hinge unit 40 in the axial direction. As described above, the second contact member 60 and the first contact member 50 are firmly fixed and the conduction is stably ensured. For example, the hinge unit receives an impact force or other external force due to the drop of the mobile phone 10. Even if 40 is moved or deformed, the continuity of the first housing 20, the hinge unit 40, and the second housing 30 is not cut off.

  The first contact member 50 includes a curved portion 504, and the contact contact portion 500 is deformed by contacting the contact 406 of the hinge unit 40. For this reason, an elastic force is generated so that the contact point 406 and the contact point contact part 500 are in contact with each other, and the stability of these connections is ensured.

  Note that the second contact member 60 and the first contact member 50 can be easily mass-produced by laser processing or press processing of a single plate material and are economically excellent.
