Description

  The present invention relates to an electronic device in which a movable panel is provided so as to be movable on the front surface of the device main body, and particularly to an electronic device in which the device main body and the movable panel are connected via a flexible wiring member.

  In in-vehicle electronic devices, etc., a movable panel having an operation member and a display member is provided on the front surface of the device main body, and the movable panel is set to a protruding posture moved forward from an approaching posture approaching the front surface of the device main body. There is something to be done.

  For example, in the approaching posture, the movable panel is in a vertical posture so as to cover the front surface of the device body, and the operation member provided on the front surface of the movable panel can be operated from the front. Further, in the projecting posture, the lower end of the movable panel moves forward and is inclined obliquely, and the operation member provided on the front surface of the movable panel can be operated from obliquely above.

  Since the movable panel incorporates a switch and other input elements operated by the operation member, a liquid crystal display panel functioning as the display member, and an illumination member, a circuit inside the device main body. And the inside of the movable panel must be electrically connected. Therefore, a flexible flexible cable is used as a connection member for connecting the apparatus main body and the movable panel.

  Inside the device main body, the base end portion of the flexible cable is connected to a circuit board via a connector or the like. As the flexible cable routing structure, the flexible cable does not hinder the protruding movement of the movable panel, and when the flexible cable is pulled along with the protruding movement of the movable panel, the flexible cable is connected to the circuit board. It is necessary that excessive force does not act.

Therefore, Patent Document 1 below discloses that a flexible cable is sandwiched between a back surface of a movable panel and a front surface of a device body. In addition, the device described in Patent Document 2 has a structure in which a shaft is provided inside the device body, a flexible cable drawn from the substrate is wound around the shaft, and is further drawn toward the movable panel in a bent state. It has become.

  However, in the thing of patent document 1, since the flexible cable is always pinched | interposed between the front surface of an apparatus main body, and the back surface of a movable panel, when the movable panel becomes an approaching posture, the flexible cable is There is a risk that it will be strongly folded, resulting in disconnection.

  Moreover, the thing of patent document 2 prevents the force from acting directly on a connector even if a tensile force acts on a flexible cable by winding a flexible cable around the axis | shaft in an apparatus main body. However, since the flexible cable is constrained to be difficult to move between the shaft and the connector, the flexible cable moves freely within the device body when the movable panel moves toward the device body. The flexible cable drawn out of the device body cannot be reliably returned to the inside of the device body. That is, the flexible cable cannot always be provided with a margin in the device body, and as a result, an excessive force tends to act on the connection portion between the flexible cable and the substrate in the device body.

  The present invention solves the above-described conventional problems, and can prevent an unreasonable force from acting on a connecting portion of a wiring member in a device body when a pulling force acts on the wiring member. It is an object of the present invention to provide an electronic device capable of always wiring with sufficient margin in the device body.

The present invention has a device main body, a movable panel that moves forward from the front surface of the device main body to a protruding posture, and a flexible wiring member that connects the inside of the device main body and the movable panel. In the electronic device in which an insertion hole for pulling out the wiring member toward the movable panel is formed in the device main body,
The wiring member has a wiring portion extending in a direction intersecting with a drawing direction from the insertion hole inside the device main body, and a front portion side of the wiring portion is curved and pulled out to the outside from the insertion hole. And
An auxiliary plate is attached to the inner surface of the wiring portion opposite to the surface facing the insertion hole, and a free end of the auxiliary plate that is not fixed to the wiring member is opposed to a barrier surface in the device body. The free end can be brought into contact with the barrier surface when a force withdrawing from the insertion hole is applied to the wiring member.

  In this electronic device, since the auxiliary plate is attached to the wiring member in a cantilever state in the device main body, when an excessive pulling force is applied to the wiring member, the free end of the auxiliary plate hits the barrier surface and beyond. The wiring member is not pulled out. For this reason, an unreasonable force does not act on the connection portion between the wiring member and the substrate in the apparatus main body. In addition, since the auxiliary plate can prevent the wiring member from being forcibly pulled out of the apparatus main body, it is possible to always arrange the wiring member within the apparatus main body with a margin.

  For example, in the present invention, the wiring member is formed with a curved allowance portion on the base side of the wiring portion to which the auxiliary plate is attached.

  Furthermore, the wiring member is connected to the substrate by being bent in the same direction as the wiring portion on the base side with respect to the bending allowance portion.

  As described above, when the bending allowance is formed in the wiring member in the device body, the bending allowance portion does not extend when the auxiliary plate hits the barrier surface. When returning toward the front, the wiring member is more easily bent in the apparatus main body, and the wiring member is easily returned to the inside of the apparatus main body.

  In the present invention, it is preferable that the barrier surface extends substantially in parallel with a drawing direction from the insertion hole, and the free end is applied when a force drawn from the insertion hole is applied to the wiring member. Is slidable in a direction away from the insertion hole in contact with the barrier surface.

  If comprised as mentioned above, when the free end of an auxiliary | assistant plate slides along a barrier surface, a wiring member can be further pulled out of an apparatus main body, and when the extraction | drawer force is cancelled | released, an auxiliary | assistant plate It becomes easy for the wiring member to return to the inside of the apparatus main body by the restoring force of.

  Further, it is more preferable that a stopper is provided in the device main body so that the free end sliding on the barrier surface hits.

  When the stopper is provided, it is possible to prevent the wiring member from being pulled out more than necessary.

In the present invention, the auxiliary plate is preferably flexible.
When the holding plate is flexible, the wiring member can freely move without disturbing the deformation of the wiring member in the apparatus main body. In addition, the function of returning the wiring member into the device main body is enhanced.

  In the electronic device of the present invention, the wiring member can freely move in the device main body, and when an excessive pulling force acts on the wiring member, the connection portion between the wiring member and the circuit board in the device main body Can be protected.

As shown in FIGS. 2 and 3, a drive unit 6 is provided inside the device body 2, and the drive unit 6 is a rotational drive unit that rotationally drives a disk D inserted from a disk insertion slot 5a. 8a is provided.

  As shown in FIGS. 2 and 3, a main circuit board 25 is provided in the housing 2a, and a panel circuit board 26 is provided in the movable panel 20, and the main circuit board 25 and the panel circuit board are provided. 26 is connected via a flexible cable (flexible wiring member) 27 that can be bent and deformed freely. The flexible cable 27 is connected to the main circuit board 25 via a connector 28 and is connected to the panel circuit board 26 via a connector 29.

  The connector 28 includes a plug 28 a provided at an end portion on the base side of the flexible cable 27 and a socket 28 b provided on the main circuit board 25. The connector 29 includes a plug 29 a provided at the end of the flexible cable 27 on the front side and a socket 29 b provided on the panel circuit board 26.

  At a position below the front panel 5 on the device main body 2 side, an insertion hole 5b for drawing the flexible cable 27 to the outside of the device main body 2 is formed. The drawing direction of the flexible cable 27 through the insertion hole 5b is the horizontal direction (Y1 direction). An insertion hole 20c is formed in the central portion of the back surface 20b on the movable panel 20 side in the Z direction, and the flexible cable 27 enters the inside of the movable panel 20 through the insertion hole 20c.

  As shown in FIGS. 2 and 3 and FIG. 4, the end of the flexible cable 27 on the base side is connected to the main circuit board 25 via a connector 28 in the housing 2 a. The flexible cable 27 includes a first wiring portion 27a that extends substantially straight from the connector 28 in the vertical direction (Z1 direction) with respect to the main circuit board 25, and a substantially U-shape at the tip of the first wiring portion 27a. It has a bending allowance portion 27b that is curved into a shape, and a second wiring portion 27c that extends substantially straight from the front portion of the bending allowance portion 27b downward (Z2 direction).

  The second wiring portion 27c is substantially parallel to the front surface 2A, and intersects the direction (Y direction) in which the flexible cable 27 is pulled out in the insertion hole 5b (Z direction substantially orthogonal). It extends toward. Therefore, the flexible cable 27 is provided with a curved portion 27d at a portion ahead of the second wiring portion 27c, and is bent by the curved portion 27d and drawn out of the device body 2 from the insertion hole 5b. .

  As shown in FIG. 4, in the second wiring portion 27 c of the flexible cable 27, an auxiliary plate 30 is attached to the inner surface facing the side opposite to the surface facing the front panel 5 and the insertion hole 5 b. The auxiliary plate 30 is made of a flexible synthetic resin material such as PP (polypropylene) or PET (polyethylene terephthalate).

  The auxiliary plate 30 is bonded and fixed to the inner surface of the second wiring portion 27c via an adhesive layer 31 at a base portion having a predetermined length from the base end 30a. The base end 30a is directed in the base direction of the flexible cable 27 (the direction opposite to the drawing direction through the insertion hole 5b). Further, the free end 30b of the auxiliary plate 30 that is not bonded to the flexible cable 27 is directed in the tip direction of the flexible cable 27 (the direction of drawing through the insertion hole 5b).

  However, since the second wiring portion 27 c is oriented substantially vertically, the free end 30 b of the auxiliary plate 30 faces the barrier surface 25 a that is the upper surface of the main circuit board 25.

  In the disk device 1, the upper end 20 </ b> A side of the movable panel 20 is located inside both the front panels 5 so that the movable panel 20 can move from the approaching posture shown in FIGS. 1 and 2 to the protruding posture shown in FIG. 3. The side surface is supported so as to be movable in the vertical direction, and the lower end 20B of the movable panel 20 is movable in the front-rear direction (Y direction).

  A slide member 21 that moves forward and backward in the Y direction is provided in the housing 2a. The slide member 21 is driven by an opening / closing motor (not shown) so as to protrude forward from the front surface 2A and to retreat into the housing 2a.

  When the slide member 21 advances in the Y1 direction from the state shown in FIG. 2, the lower portion 20B of the movable panel 20 is pushed forward by the tip 21a of the slide member 21, and the lower end 20B of the movable panel 20 in the approaching posture is moved forward. Move to. As a result, the movable panel 20 has a tilted attitude indicated by a broken line in FIG. 3 and a substantially horizontal attitude indicated by a solid line.

  When the slide member 21 moves backward in the Y2 direction from the state of FIG. 3, the lower end 20B of the movable panel 20 is drawn toward the front surface 2A by the tip 21a of the slide member 21, and the movable panel 20 is in the approaching posture shown in FIG. Return to.

  When the movable panel 20 is in the approaching position shown in FIG. 2, the flexible cable 27 is drawn into the movable panel 20. At this time, the flexible cable 27 always forms a margin portion 27b in the flexible cable 27 in the housing 2a. Has been. When the movable panel 20 is in the protruding posture shown in FIG. 3, tension is applied to the flexible cable 27 by the movement of the movable panel 20.

  In this embodiment, when the tension acts, the flexible cable 27 is pulled out from the inside of the movable panel 20 through the insertion hole 20c. At this time, the flexible cable 27 positioned inside the housing 2a is connected to the flexible cable 27. The pulling force F also acts on it. However, in the housing 2a, the flexible cable 27 is always wired with a margin, and the bending margin portion 27b can always be secured.

  5 and 6 show that when the movable panel 20 shifts to the projecting posture, the flexible cable 27 when the pulling force F in the Y1 direction acts on the flexible cable 27 located in the insertion hole 5b of the front panel 5 is shown. The operation is shown.

  When the pulling force F acts, the flexible cable 27 located in the housing 2a tries to move the bending allowance portion 27b toward the main circuit board 25. At this time, the free end 30b of the auxiliary plate 30 is It hits the barrier surface 25a which is the upper surface of the main circuit board 25. This prevents the flexible cable 27 located in the housing 2a from being further drawn out of the device body 2 through the insertion hole 5b. Therefore, the flexible cable 27 can always bend the margin portion 27b in the housing 2a, and an unreasonable force does not act on the connector 28, so that the connection state between the flexible cable 27 and the main circuit board 25 is maintained. It can be reliably maintained.

  FIG. 6 shows a state in which a drawing force F is further applied to the flexible cable 27 after the free end 30b of the auxiliary plate 30 abuts against the barrier surface 25a. At this time, as the flexible cable 27 is pulled out from the insertion hole 5b, the free end 30b slides on the barrier surface 25a and moves away from the insertion hole 5b (Y2 direction), while the auxiliary plate 30 is elastic. Deform. Further, when the pulling force F acts, the free end 30b hits the socket 28b functioning as a stopper, and no more can move in the Y2 direction.

  Therefore, even if an excessive pulling force F acts on the flexible cable 27 that passes through the insertion hole 5b, the flexible cable 27 is always formed with a margin part 27b in the flexible cable 27. Therefore, an excessive force does not act on the connector 28.

  When the flexible cable 27 in the housing 2a is in the state shown in FIG. 6, when the movable panel 20 moves toward the approaching posture shown in FIG. 2, the auxiliary plate 30 is restored to a flat state by its own elastic force. Then, the state returns to the state shown in FIG. Therefore, a part of the flexible cable 27 that has come out of the housing 2a can be automatically returned into the housing 2a through the insertion hole 5b.

  As described above, since the flexible cable 27 always bends and forms the margin portion 27b inside the housing 2a, the flexible cable 27 in the housing 2a can move freely, and excessive stress is locally generated. Since it does not act, there is no fear of disconnection and connection failure at the connector 28 is less likely to occur.

The present invention is not limited to the embodiment described above, and various modifications can be made.
For example, in the housing 2a, the flexible cable 27 has a wiring part extending so as to hang down in the Z2 direction from the substrate positioned above, and the auxiliary plate 30 is attached to the wiring part. The portion may be curved and pulled out from the insertion hole 5b. Alternatively, the flexible cable 27 extends in the Y1 direction within the housing 2a, and a tip portion thereof is bent in the Z2 direction to form a wiring portion. The auxiliary plate 30 is attached to the wiring portion, and is further bent and inserted. It may be pulled out from the hole 5b.

  Also in the above-described embodiment, a margin can always be formed in the flexible cable 27 in the housing 2a, and disconnection and poor connection can be prevented.

  Further, the movable panel 20 is not limited to a slanting inclination in a projecting posture, and may move in parallel as it is without changing the inclination. Alternatively, the movable panel having a display screen or the like may move from a posture housed in the housing 2a to a projecting posture that projects to the outside of the housing 2a, and from the inside of the housing 2a. After projecting and moving forward, the movable panel may rise so that it becomes an inclined posture or a vertical posture.

  The flexible wiring member is not limited to the flexible cable, and may be a linear cable or a flat cable in which linear wiring members are connected in parallel. Further, the connection between the wiring member and the main circuit board 25 may be soldering or the like.
