Abstract

(57) [Abstract] [Purpose] To make it possible to easily route the wiring drawn out of the housing of an electronic device. [Structure] In a corner portion of a side plate 10d and a side plate 10e of a housing 10 of a vehicle-mounted disc changer, a top portion 1 of the corner portion is formed.
A recess 12 is formed to leave the inside of the housing 10 except for 1, and the wirings 2 and 3 are drawn out from the bottom surface 12a of the recess 12. Since the wirings 2 and 3 are pulled out from the inside of the recess 12, even if the side plate 10d or the side plate 12e is brought into close contact with a wall or the like, the pulling-out of the wirings 2 and 3 is not affected. Further, even if the wirings 2 and 3 are curved in the direction of the side plate 10d or 10e, the amount of the bending is reduced, and the wiring is not subjected to excessive internal stress.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle-mounted disc changer and other vehicle-mounted or home-use or office-use electronic devices, and more particularly to a wiring structure for drawing external wiring from a housing of the electronic device.

[0002]

[Prior art]

 FIG. 6 is a perspective view showing a part of the housing of a conventional vehicle-mounted disc changer. FIG. 6 shows the corners of the side plate 1a on the rear surface and the side plate 1b on the side surface of the housing 1 of the disc changer. Two kinds of external wirings 2 and 3 are drawn out from the edge of the rear side plate 1a. One wiring 2 is, for example, for a power supply, and passes through a rubber bush 4 fitted in a hole of the side plate 1a of the housing 1 and is drawn out from the inside of the housing to the outside. The other wiring 3 is for an audio signal, and is composed of an optical fiber in FIG. A plug 5 is attached to an end portion of the wiring 3, and the plug 5 is fitted to the optical repeater 6 attached to the side plate 1a.

[0003]

[Problems to be solved by the device]

 As shown in FIG. 6, conventionally, the wirings 2 and 3 are vertically drawn out from the side plate 1a on the rear surface of the housing. Therefore, for example, as shown in FIG. 7, when the side plate 1a is installed to face the room wall B in the trunk room of an automobile or the like, in order to pull out the wirings 2 and 3 to the side, the side plate 1a and the room wall B are drawn. A gap W for bending the wiring must be provided between and. Therefore, the space in the luggage compartment could not be used effectively. Further, as shown by the solid lines in FIG. 7, when the wirings 2 and 3 are drawn out in a direction parallel to the side plate 1a, the wirings 2 and 3 are connected to the center line O of the rubber bush 4 and the plug 5 by 90. I had to bend it every time. Alternatively, as shown by the chain line in FIG. 7, when the wirings 2 and 3 are to be drawn out in a direction parallel to the side plate 1b, the wirings 2 and 3 are curved at a large angle of 180 degrees with respect to the center line O. I had to let him pull it out. Therefore, the internal stress acting on the wirings 2 and 3 was high, and it was easy to cause disconnection. In particular, as shown in FIGS. 6 and 7, when the wiring 3 is an optical fiber, it has to be bent with a large curvature because it is less flexible than the conductor wire, and therefore the space W shown in FIG. More widely needed.

The present invention is intended to solve the above-mentioned conventional problems, and an object thereof is to provide a wiring structure of an electronic device that can be pulled out without giving unnecessary stress to external wiring from a housing. There is.

[0005]

[Means for Solving the Problems]

 According to the wiring structure of an electronic device according to the present invention, a recess is formed in a corner of a casing of the electronic device so as to be inward of the device, leaving the top of the corner, and external wiring is provided from the bottom of the recess. Is being drawn out.

Further, in the above means, it is preferable that the bottom surface of the concave portion is positioned at an angle of about 45 degrees with respect to both side plates adjacent to each other with the corner portion interposed therebetween.

[0007]

[Action]

 In the above means, the wiring is drawn to the outside from the inside of the recess that enters inside the device rather than the top of the corner of the housing. Since the top of the corner remains, the internal parts of the housing can be placed inside the corner, and the substantial capacity inside the housing does not change. Further, since the wiring is pulled out from the inside of the recess, it is not necessary to provide a space for routing the wiring between the side plate and the room wall, and the side plate can be closely attached to the room wall or the like.

Further, in the second means, since the bottom surface of the recess is oriented at 45 degrees with respect to the adjacent both side plates, it is assumed that the wiring drawn from this bottom surface is curved in a direction along any one of the side plates. However, the curvature of the wiring at this time becomes larger than in the conventional case, and the internal response of the wiring does not increase.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a housing of a vehicle-mounted disc changer from the back side as an example of electronic equipment, FIG. 2 is an exploded perspective view showing a structure of a corner portion of the housing, and FIGS. 3 and 4 show wiring drawing. It is a top view which shows an example of turning. In FIG. 1, reference numeral 10 is a housing of a vehicle-mounted disc changer. A front surface 10a of the housing 10 is located on the diagonally right rear side in the drawing, and a magazine M containing a plurality of disks is loaded from an insertion opening opened in the front surface 10a. Inside the housing 10, there are provided a mechanism for selecting and pulling out a disc from the magazine M, and a disc playback drive mechanism for clamping and playing back the pulled-out disc. Reference numeral 10b is a ceiling plate of the housing, and 10c is a bottom plate of the housing. Reference numeral 10d is a side plate that is the back surface of the housing, and 10e is a side plate that covers one side of the housing 10.

As shown in FIG. 1, at the corners where both side plates 10d and 10e of the housing 10 intersect, a recess 12 is formed on the bottom plate 10c side so as to enter the inside of the housing, leaving the top 11 of the corner. Has been. The external wirings 2 and 3 are drawn out from the bottom surface 12a of the recess 12. In this embodiment, as shown in FIG. 3, the bottom surface 12a of the recess 12 is arranged at an angle of 45 degrees with respect to the side plates 10d and 10e which are orthogonal to each other. The wiring 2 is a bundle of conductors and is mainly used for supplying power. The wiring 2 is inserted into the rubber bush 4 fitted to the bottom surface 12a and is pulled out from the inside of the housing 10 to the outside. The other wiring 3 is mainly for audio signals and is composed of optical fibers. A plug 5 is connected to the wiring 3, and the plug 5 is connected to the optical repeater 6 attached to the bottom surface 12a.

As shown in FIG. 2, bent pieces 21a and 21b are formed on the edge of the bottom plate 10c of the housing 10 by bending, and the bent pieces 21a and 21b are formed between the bent pieces 21a and 21b. The bottom surface 12a of the recess 12 is bent substantially vertically from the bottom plate 10c. A holding groove 12b cut from the upper edge portion is formed in the bottom surface 12a, and the rubber bush 4 is fitted in the holding groove 12b. A rectangular window 12c in which the optical repeater 6 appears is formed on the bottom surface 12a. A relay board 22 is arranged inside the bottom surface 12 a of the recess 12, and the optical repeater 6 is attached to the relay board 22. A support piece 21c is bent at the upper edge of the one bent piece 21a, and the relay board 22 is installed on the support piece 21c and fixed by screws 24. A relay connector (not shown) is mounted on the relay board 22. The wiring from the inside of the housing 10 is connected to this relay connector, and a signal is transmitted to the optical repeater 6 via the relay connector. Given. The optical repeater 6 has a light emitting means inside, and an optical signal emitted from this light emitting means is guided to the outside by the wiring 3 of the optical fiber.

As shown in FIG. 2, the ceiling plate 10b, the side plates 10d and 10e, the front face 10a, and the like of the housing 10 are integrally formed, and are covered on the bottom plate 10c. At this time, the side plate 10d is overlaid on the outer surface of the bent piece 21a, and the side plate 10e is overlaid on the outer surface of the bent piece 21b. A notch 23 is formed at the intersection of the side plates 10d and 10e, leaving the top 11, and when the side plates 10d and 10e are joined to the bottom plate 10c, the bottom surface 12a is located at the back of the notch 23, A recess 12 as shown in FIG. 1 is formed. Further, as shown in FIG. 2, a closing plate 23a is provided on the upper portion of the notch 23 so as to cover a gap between the notch 23 and the bottom surface 12a. In the above structure, the recess 12 is formed in the portion of the housing 10 that is continuous with the bottom plate 10c, and the tops 11 of the corners are left in other height ranges, so that the housing 10 is provided inside the top 11. It is possible to arrange the internal parts of the above, and the internal capacity of the housing 10 is not so small. Therefore, by setting the depth of the recess 12 and the area of the bottom surface 12a of the recess 12 to the minimum size necessary for drawing out the wiring, it is necessary to prevent the space of the mechanism and the components arranged inside the housing 10. I can't reach it.

3 and 4 are plan views of the housing 10 as seen from above the ceiling plate 10b. The rubber bush 4 which is the base of the wiring 2 and the plug 5 connected to the wiring 3 of the optical fiber are: It is located in the space of the recess 12 in the plan view. That is, the rubber bush 4 and the plug 5 are configured so as not to project outward from the side plates 10d and 10e of the housing 10 and the top 11.

Therefore, as shown in FIG. 3, for example, if the side plate 10e of the housing 10 is brought into close contact with the room wall B of the trunk room, or the side plate 10e is faced downward, the side plate 10e is brought into close contact with the room floor. However, the rubber bush 4 and the plug 5 do not hit the room wall B or the room floor. Therefore, it is possible to prevent the occurrence of obstacles such as the plug 5 colliding with the room wall B and being damaged, and as shown by the solid line in FIG. When it is pulled out in the direction (along the direction), the angle of the wirings 2 and 3 with respect to the center line O of the rubber bush 4 and the plug 5 can be set to about 45 degrees, which is shallower than 90 degrees, and the wiring curve can be curved more than before. The curvature can be increased and the stress inside the wiring does not increase. Further, as shown by the chain line in FIG. 3, even if the wirings 2 and 3 are extended substantially parallel to the side plate 10d, the detour angle of the wirings 2 and 3 with respect to the center line O of the rubber bush 4 and the plug 5 is 180. The bending stress acting on the wirings 2 and 3 is also small in this case. Therefore, no excessive force acts on the wirings 2 and 3. Since the bottom surface 12a of the concave portion is oriented at 45 degrees with respect to both side plates 10d and 10e, as shown in FIG. 4, the side plate 10d on the back side of the housing 10 is closely attached to the room wall B such as a trunk room. Alternatively, when the side plate 10d is faced downward and the side plate 10d is closely attached to the room floor, the wiring conditions of the wirings 2 and 3 are the same as in the case of FIG.

FIG. 5 shows another embodiment of the present invention. In this embodiment, both the wirings 2 and 3 are held by the rubber bush 25. A holding groove 12d into which the rubber bush 25 is fitted is formed on the bottom surface 12a of the recess 12. Also in the embodiment shown in FIG. 5, the drawing directions of the wirings 2 and 3 are the same as those in the embodiment shown in FIG. However, in the embodiment shown in FIG. 5, since the relay board 22 is not provided inside the bottom surface 12a of the recess 12, the internal space of the housing 10 inside the recess 12 can be effectively used, and the relay board 22 and the like can be effectively used. You can delete parts. Although the above-described embodiment has described the in-vehicle disc changer as the electronic device, the present invention can be applied to in-vehicle audio devices other than the disc changer, and can be applied to various electronic devices such as home and office use. The present invention can be applied to the housing.

[0016]

[Effect of device]

 As described above, according to the first aspect of the present invention, since the wiring is drawn out from the recess formed in the corner of the housing, the wiring can be routed even if the side plate of the housing is closely attached to the wall, for example. be able to. Further, since the tops of the corners of the housing remain in the portions other than the recesses, the internal parts of the housing can be arranged inside the corners, and the substantial volume in the housing is not significantly reduced.

According to the second aspect of the present invention, since the bottom surface of the recess is oriented at 45 degrees with respect to the adjacent both side plates, it is assumed that the wiring drawn from this bottom surface is curved in a direction along any one of the side plates. However, the amount of bending of the wiring at this time is reduced, and the internal stress of the wiring is not increased.
