  Then, the operator adjusts the shape of the bellows portion 41c so that the bellows portion 41c of the flat cable 40 is located between the electronic device main body 10 and the second reinforcing plate 43.

  In this way, the electronic device 1 is mounted on the vehicle.

  As shown in FIG. 5, in the assembled state, the first reinforcing plate 42 is drawn obliquely with respect to the normal direction of the opening 21 so that a part thereof is located below the cover member 20. In other words, the first reinforcing plate 42 is disposed obliquely with respect to the normal direction of the opening 21 from the inside to the outside of the housing 11 of the electronic device main body 10 via the opening 21. In the present embodiment, the surface 42 a of the first reinforcing plate 42 is in contact with the lower end of the opening 21. Part of the first reinforcing plate 42 is located below the wall surface 20 a of the cover member 20. Since the first reinforcing plate 42 abuts on the cover member 20 and the cover member 20 is supported from below by the first reinforcing plate 42, the cover member 20 is prevented from bending downward by its own weight. Have been. In other words, the cover member 20 is arranged along the opening of the housing 11 of the electronic device main body 10.

  As shown in FIG. 1, in the assembled state, the non-adhesive portion 43 b of the second reinforcing plate 43 is located between the fastened portion 110 of the vehicle and the bellows portion 41 c of the flat cable 40. This restricts the fastening member 100 fastened to the fastened portion 110 of the vehicle from coming into contact with the bellows 41c. Further, since the second reinforcing plate 43 has rigidity, the second reinforcing plate 43 is in an upright state in a direction parallel to the vertical direction. For this reason, the distance d between the second reinforcing plate 43 and the fastening member 100 is maintained at a predetermined interval. Thus, the bellows portion 41 c of the flat cable 40 is restricted by the second reinforcing plate 43 from bulging away from the side surface 11 c of the electronic device body 10. In other words, the contact of the bellows portion 41 c of the flat cable 40 with the fastening member 100 is restricted by the second reinforcing plate 43. Further, the bellows portion 41c of the flat cable 40 is held by the second reinforcing plate 43 at a position where the distance between the bellows portion 41c of the flat cable 40 and the fastening member 100 is equal to or longer than the distance d.

  As described above, according to the present embodiment, in the assembled state, the non-adhesive portion 43b of the second reinforcing plate 43 is positioned between the fastened portion 110 of the vehicle and the bellows portion 41c of the flat cable 40. I have. For this reason, this embodiment can regulate that the fastening member 100 fastened to the to-be-fastened part 110 of a vehicle contacts the bellows part 41c. According to the present embodiment, for example, even when the fastening member 100 has an unexpected length under the neck and enters the electronic device 1, the fastening member 100 is not attached to the non-adhesive portion 43 b of the second reinforcing plate 43. 100 can be restricted from contacting the bellows portion 41c.

  Moreover, according to the present embodiment, the second reinforcing plate 43 can restrict the bellows portion 41c of the flat cable 40 from bulging in a direction away from the side surface 11c of the electronic device body 10. In other words, according to the present embodiment, the bellows portion 41c of the flat cable 40 is positioned by the second reinforcing plate 43 such that the distance between the bellows portion 41c of the flat cable 40 and the fastening member 100 is equal to or longer than the distance d. Can be arranged.

  As described above, according to the present embodiment, the bellows portion 41 c of the flat cable 40 can reliably restrict the contact with the fastening member 100 by the second reinforcing plate 43.

  According to the present embodiment, the second reinforcing plate 43 is formed in a convex shape. For this reason, the area of the second reinforcing plate 43 is smaller than that of the rectangular reinforcing plate 310 having the same length in the wiring direction of the flat cable 40.

  The rectangular reinforcing plate 310 will be described with reference to FIG. FIG. 10 is a partially enlarged view showing a reinforcing plate of a rectangular flat cable. The reinforcing plate 310 has the same length as the length h1 of the second reinforcing plate 43 of the present embodiment in the wiring direction. The reinforcing plate 310 is bonded to one end 41 a of the flat cable main body 41. In other words, the reinforcing plate 310 does not have a non-adhered portion that is not adhered to the one end 41a of the flat cable main body 41. For this reason, for example, when a force from the side indicated by an arrow F <b> 1 acts on the reinforcing plate 310 inserted into the connector 31 of the board 30, the moment acting on the reinforcing plate 310 acts on the second reinforcing plate 43. It is larger than the moment. For this reason, the reinforcing plate 310 is more likely to fall off the connector 31 of the board 30 than the second reinforcing plate 43.

  On the other hand, in the present embodiment, since the second reinforcing plate 43 inserted into the connector 31 of the board 30 is formed in a convex shape, a portion receiving a force from the side is small. Further, according to the present embodiment, even when a force from the side, for example, indicated by an arrow F acts on the second reinforcing plate 43, the moment acting on the second reinforcing plate 43 can be reduced. In other words, the second reinforcing plate 43 can reduce the moment because the portion that receives the force from the side is located near the portion of the board 30 that is inserted into the connector 31. Thus, according to the present embodiment, it is possible to prevent the second reinforcing plate 43 from falling off the connector 31 of the board 30. In other words, according to the present embodiment, it is possible to prevent the flat cable 40 from falling off the connector 31 of the board 30.

  According to the present embodiment, the second reinforcing plate 43 has the non-adhesive portion 43b. Thus, according to the present embodiment, the stress acting on the connector 31 of the board 30 can be reduced by reducing the area of the portion where the second reinforcing plate 43 is bonded to the flat cable 40.

  Moreover, according to the present embodiment, the second reinforcing plate 43 has the protruding portion 43c. For this reason, according to the present embodiment, since the worker can grip the protruding portion 43c, it is possible to prevent the handleability during the assembling work from being impaired.

  According to the present embodiment, as shown in FIG. 1, even when the fastening member 100 is arranged near the electronic device 1, it is possible to reliably restrict the fastening member 100 from contacting the flat cable 40. Can be. For this reason, according to the present embodiment, the degree of freedom of the mounting position of the electronic device 1 is increased.

  According to the present embodiment, in the assembled state, the first reinforcing plate 42 is drawn obliquely with respect to the normal direction of the opening 21 so that a part thereof is located below the cover member 20. For this reason, in the present embodiment, the cover member 20 abuts on the first reinforcing plate 42 and is supported from below by the first reinforcing plate 42, thereby restricting the cover member 20 from bending downward by its own weight. be able to.

  The bending of the cover member 20 will be described with reference to FIG. FIG. 9 is a perspective view illustrating bending of the cover member. In FIG. 9, a flat cable 40 is not connected to the electronic device main body 10. Since the cover member 20 is not supported from below by the first reinforcing plate 42, the cover member 20 is bent downward by its own weight.

  On the other hand, in the present embodiment, for example, the contact of the cover member 20 with the electronic component mounted on the substrate 30 is restricted. Thereby, in the present embodiment, the clearance between the cover member 20 and the substrate 30 can be secured. For this reason, in the present embodiment, it is possible to suppress the occurrence of noise due to the contact of the cover member 20 with the electronic component mounted on the substrate 30.

  In the above, the electronic device 1 according to the present invention has been described, but may be implemented in various different forms other than the above-described embodiment. The configuration of the second reinforcing plate 43 described above is an example, and is not limited to this. For example, the second reinforcing plate 43 may have another shape such as a triangular shape or a trapezoidal shape.
