FIG. 2 is a longitudinal sectional view showing the configuration of the electronic device when the movable monitor 21 moves at its maximum. FIG. 3 is a diagram showing the positional relationship between the guide groove 22b and the support plate 42b. FIG. 4 is a diagram of the guide groove 22b viewed from above. FIG. 5 is a longitudinal cross-sectional view showing the configuration of the guide groove 22b.

The electronic device shown in FIGS. 1 and 2 is, for example, an in-vehicle electronic device such as a navigation device. This electronic device includes a housing 10 and a movable part 20. The housing 10 is placed on the rear side of the electronic device, and the movable part 20 is placed on the front side of the electronic device. The housing 10 is fixed to a vehicle body member (not shown) that constitutes a vehicle body. The movable part 20 is fixed to the front surface of the housing 10.

The housing 10 and the movable part 20 are electrically connected. Specifically, the casing 10 houses a substrate 41 that serves as a first substrate. This board 41 has a connector 41a. The connector 41a is provided on the top surface of the board 41. On the other hand, the movable part 20 houses a substrate 42 that becomes a second substrate. This board 42 has a connector 42a. The connector 42a is provided on the rear surface of the board 42.

Although the substrate 41 is placed horizontally and the substrate 42 is placed vertically, the substrate 41 may be placed vertically.

The connector 41a of the board 41 and the connector 42a of the board 42 are electrically connected via a signal line. In the electronic device according to the first embodiment, the signal line is an FPC (Flexible Printed Circuit) 43. In addition to the FPC 43, the signal line may be a lead cable or an FFC (Flexible Flat Cable), for example.

As shown in FIGS. 1 and 2, the housing 10 has a box shape. This housing 10 has a case member 11, a cover member 12, and a rigid portion 13.

The case member 11 is fixed to the vehicle body member. This case member 11 has, for example, a box shape with an open top. A board 41 is housed inside the case member 11 . Further, the case member 11 has a communication hole 11a. The communication hole 11a is formed in the front wall of the case member 11. This communication hole 11a is a hole that allows the inside of the casing 10 and the inside of the movable part 20 to communicate with each other. The FPC 43 passes through the communication hole 11a.

The cover member 12 is formed into a flat plate shape, for example, and closes the upper opening of the case member 11. Attachment of the board 41 into the housing 10 and processing of the extra length of the FPC 43 within the housing 10 are performed with the cover member 12 removed from the case member 11.

A plurality of rigid parts 13 are provided inside the casing 10 and are integrated with the FPC 43 . This rigid portion 13 curves the extra length portion 43a of the FPC 43 inside the housing 10. Further, the rigid portion 13 has higher rigidity than the FPC 43. Such a rigid part 13 is, for example, a PET (polyethylene terephthalate) resin sheet material, and the FPC 43 is attached to the inside of the casing 10 using the PET resin sheet material. Therefore, the rigid portion 13 can maintain the extra length portion 43a of the FPC 43 in a curved state inside the housing 10, no matter what position the movable monitor 21 (described later) moves.

That is, the electronic device adjusts the curved position of the FPC 43 and the curvature of the curved portion by changing the installed quantity and installation position of the rigid portion 13, and appropriately processes the extra length of the FPC 43 within the housing 10. Can be done.

Here, the extra length portion 43a of the FPC 43 refers to the extra length of the FPC 43 provided to facilitate the connection work when connecting the FPC 43 between the connector 41a of the board 41 and the connector 42a of the board 42. It's about minutes. The length of the extra length portion 43a is the length of the portion curved by the rigid portion 13. FIG. 1 shows an example in which the two rigid parts 13 provided on the inner surface of the case member 11 and the FPC 43 are integrated, and the extra length of the FPC 43 is processed. The length of the extra length portion 43a in FIG. 1 is the length of the portion curved between the two rigid portions 13.

As shown in FIGS. 1 and 2, the movable section 20 includes a movable monitor 21 and a fixed panel 22. The movable monitor 21 is arranged on the front side of the movable part 20. The fixed panel 22 is arranged on the rear side of the movable part 20.

The movable monitor 21 is supported by a fixed panel 22 so as to be movable in the vertical direction. A board 42 is fixed inside the movable monitor 21 .

As shown in FIGS. 1 to 3, the substrate 42 fixed inside the movable monitor 21 has a support plate 42b serving as a support section. The support plate 42b projects rearward from the connector 42a. This support plate 42b supports the FPC 43 disposed within the movable portion 20 in its length direction. Further, the width of the support plate 42b is greater than or equal to the width of the FPC 43.

Here, the support plate 42b is formed into a flat plate shape and has an upper surface and a lower surface. Although the support plate 42b supports the FPC 43 on its lower surface, it may also support the FPC 43 on its upper surface. Further, although the support plate 42b is provided on the connector 42a, it may be provided on the rear surface of the board 42.

As shown in FIGS. 1 to 5, the fixed panel 22 is fixed to the front surface of the case member 11. This fixed panel 22 has a communication hole 22a and a guide groove 22b serving as a guide portion.

The communication hole 22a faces the communication hole 11a of the case member 11. This communication hole 22a is a hole that allows the inside of the casing 10 and the inside of the movable part 20 to communicate with each other. The FPC 43 passes through the communication hole 22a.

The guide groove 22b guides the FPC 43 between the inside of the housing 10 and the inside of the movable part 20. As shown in FIG. 3, the guide groove 22b is provided below the support plate 42b and is inclined with respect to the support plate 42b. Furthermore, the support plate 42b and the guide groove 22b overlap in the vertical direction.

Specifically, the guide groove 22b gradually slopes downward from the movable monitor 21 side toward the fixed panel 22 side. The upper end of the guide groove 22b is a free end, and the lower end of the guide groove 22b is connected to the lower edge of the communication hole 22a. At this time, the tip of the support plate 42b is arranged closer to the fixed panel 22 than the upper end of the guide groove 22b and closer to the movable monitor 21 than the lower end of the guide groove 22b. The upper end of the guide groove 22b constitutes one end on the movable monitor side, and the lower end of the guide groove 22b constitutes the other end on the fixed panel side.

Moreover, as shown in FIG. 4, the groove width dimension of the guide groove 22b is slightly wider than the width dimension of the FPC 43. Moreover, the groove depth dimension of the guide groove 22b is larger than the thickness dimension of the FPC 43. Therefore, the FPC 43 can be easily accommodated in the guide groove 22b, and its position in the width direction is restricted. That is, the guide groove 22b prevents the FPC 43 from shifting laterally.

Therefore, by being supported by the support plate 42b, the FPC 43 is pressed into the guide groove 22b even when the movable monitor 21 moves up and down. Moreover, as shown in FIGS. 1 and 2, since the electronic device includes a rigid portion 13 integrated with the FPC 43 inside the casing 10, the position where the extra length 43a of the FPC 43 is routed, , the curved state of the extra length portion 43a does not change. At this time, between the length of the extra length portion 43a and the maximum movement amount L of the movable monitor 21, for example, the length obtained by doubling the length of the extra length portion 43a is longer than the maximum movement amount L. There is a relationship of becoming.

Note that, as shown in FIG. 1, the inclination angle α of the guide groove 22b with respect to the support plate 42b is, for example, 55 to 70°.

Furthermore, as shown in FIG. 5, at least one of the upper and lower ends of the guide groove 22b may be rounded. Therefore, the guide groove 22b can suppress damage to the FPC 43 during guiding. FIG. 5 shows an example in which the upper end of the guide groove 22b is rounded.

As described above, the electronic device according to the first embodiment includes the casing 10 that houses the board 41 and the movable part 20 that houses the board 42 that is connected to the board 41 via the FPC 43. A fixed panel 22 fixed to the body 10, a movable monitor 21 supported movably in the vertical direction on the fixed panel 22 and to which a board 42 is fixed, and a movable part 20 that protrudes from the board 42 toward the fixed panel 22. It has a support plate 42b that supports the FPC 43 disposed inside the housing, and a guide groove 22b that is provided below the support plate 42b and guides the FPC 43 between the inside of the casing 10 and the inside of the movable part 20. However, the guide groove 22b and the support plate 42b are arranged to overlap in the vertical direction. Therefore, the electronic device can process the excess wiring length inside the casing 10.

Further, by having the above-described configuration of the electronic device, there is no need to process the excess wiring inside the movable portion 20, so that the movable portion 20 can be made smaller. Furthermore, since the electronic device does not need to provide an opening in the movable part 20 for processing the excess wiring length and a cover to close this opening, the configuration of the movable part 20 can be simplified. Can be done.

The tip of the support plate 42b is arranged closer to the fixed panel 22 than one end of the guide groove 22b and closer to the movable monitor 21 than the other end of the guide groove 22b. Therefore, in the electronic device, even if the movable monitor 21 moves up and down, the FPC 43 can always be placed on the guide groove 22b.

The guide groove 22b gradually slopes downward as it goes from the movable monitor 21 side to the fixed panel 22 side. Thereby, the electronic device can easily guide the FPC 43 toward the inside of the housing 10.

The guide groove 22b has a groove shape. Therefore, in the electronic device, the FPC 43 can be easily accommodated in the guide groove 22b, so that lateral displacement of the FPC 43 can be prevented.

At least one end of both ends of the guide groove 22b is rounded. Therefore, the electronic device can prevent damage to the FPC 43 when guiding the FPC 43 in the guide groove 22b.

The electronic device includes a rigid section 13 that is provided inside the housing 10 and bends the FPC 43 arranged inside the housing 10 . Thereby, by integrating the rigid portion 13 and the FPC 43, the electronic device can be fixed at a desired position with the extra length portion 43a of the FPC 43 curved.

Note that, within the scope of the disclosure, any component of the embodiments may be modified or any component of the embodiments may be omitted.
