Concerning structure.
[0002]
[Prior art]
When this type of electronic circuit wiring connection structure is a car audio device, for example, the electronic device 1 is divided into a main housing 2 and a movable panel housing 6 as shown in FIG. According to the operation mode, the movable panel housing 6 is closed with respect to the main housing 2 with the lower part of the front as the rotation axis as shown in FIG. 4, and a switch button disposed on the surface of the movable panel housing 6 is operated. Alternatively, the switch is arranged in an open state as shown in FIG. 5 so that the switch button disposed on the back side of the movable panel housing 6 can be operated.
[0003]
In addition, a circuit board 3 for performing a predetermined electrical operation is fixed to the main casing 2, a jumper connection connector 3 a is fixed to a part of the circuit board 3, and the circuit board 7 is also fixed to the movable panel casing 6. A jumper connection connector 7a is fixed to a part thereof.
[0004]
Each of the connector 3a and the connector 7a is detachably coupled to one end and the other end of the flexible connection substrate 4 on which a strip-shaped connection conductor is formed, and a winding storage portion 5 is disposed at an intermediate portion thereof. A main housing side buffer portion 4a is formed in the direction of the connector 3a of the take-up storage portion 5, and a movable panel side buffer portion 4b is formed in the direction of the connector 7a.
[0005]
The winding storage part 5 is wound up to buffer the change in the length of the movable panel side buffer part 4b by being moved between the open state and the closed state of the movable panel housing 6, As shown in FIG. 6, a shaft 8 having a smaller diameter than the outer diameter of the winding roller 10 is provided on one end surface of the winding roller 10 having a circular cross section, and a long shaft 9 having a smaller diameter is integrally formed on the other end surface. The winding roller 10 is rotatably supported by the shaft 8 and the shaft 9 being rotatably supported with respect to the main casing 2, and the winding roller 10 is supported by a spring 12 having a storing force in the torsional direction. Is applied to the take-up roller 10 by fixing one end of the spring 12 wound around the shaft 9 to the stationary member and the other end to a part of the take-up roller 10. A rotational force in a predetermined direction is given. Reference numeral 11 denotes a slit, and the intermediate portion of the flexible connection substrate 4 is loosely fitted and inserted while maintaining a sliding state.
[0006]
Therefore, as shown in FIG. 4, when the movable panel housing 6 is closed with respect to the main housing 2, the winding portion around the winding roller 10 is reduced as shown in FIG. When the length of the portion 4b is set to a relatively long value from the winding storage portion 5 to the connector 7a, on the other hand, as shown in FIG. 5, when the movable panel housing 6 is opened with respect to the main housing 2 As shown in FIG. 8, the intermediate portion of the flexible connection board 4 is slid in the slit 11 by the rotational energy of the winding roller 10, and the length of the movable panel side buffer 4b is shortened. The
[0007]
Whether the movable panel housing 6 is closed or opened with respect to the main housing 2, the length of the main housing buffer 4a is not changed, and the length of the movable panel buffer 4b is not changed. Only the change is made.
[0008]
Further, the structure of the take-up storage portion 5 is provided with a gear at its end, not shown, and winds up the flexible connection board surplus length generated between the main housing and the movable panel housing in conjunction with the opening and closing of the movable panel housing. There is also an example configured as described above (for example, disclosed in Patent Document 1).

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 to 4. First, a first embodiment will be described with reference to FIGS. 1 and 2.
[0022]
1 and 2 is divided into a main housing 13 and a movable panel housing 14, and the movable panel housing 14 is closed with respect to the main housing 13 as shown in FIG. It is configured to be movable in the open state as shown in FIG.
[0023]
A circuit board 15 for executing a predetermined electrical operation is fixed to the main housing 13, a mounting electronic component 16 is mounted on one surface, and a jumper connection connector 17 is fixed on the other surface. A circuit board 21 is also fixed to the housing 14, a mounting electronic component 22 is mounted on one surface, and a jumper connector 23 is fixed on the other surface.
[0024]
Each of the connector 17 and the connector 23 is detachably coupled to one end and the other end of the flexible connection board 18 on which a strip-shaped connection conductor is formed, and a reinforcing member 19 is fixed to the surface of the intermediate portion.
[0025]
The reinforcing member 19 is fixed to an intermediate portion of the flexible connection board 18 by means of adhesion or the like, and the material thereof is formed of a synthetic resin plate having rigidity higher than that of the flexible connection board 18 or flexible connection. The substrate 18 is made of a thick plate made of the same material as the substrate 18 and has a substantially large rigidity.
[0026]
Therefore, in the state where the movable panel housing 14 is closed (the state shown in FIG. 1), the flexible connection board 18 is stretched between the connector 17 and the connector 23, and the main housing side buffer 18 a is provided in the direction of the connector 17. The movable panel side buffer portion 18b is provided in the direction of the movable panel housing 14.
