Description

The present invention relates to a board connecting device for connecting a pair of printed boards (hereinafter abbreviated as boards) used in an electronic device such as a disc device (DVD player, DVD recorder, video device integrated DVD). The electronic device can be thinned.

An example of a disk device is shown in FIG. This is a DVD integrated with a video device, and a DVD player (or DVD recorder) 2 for reproducing the disk D and a video for reproducing the tape cassette T in front of the housing 1. The device 3 is disposed, and the AV substrate (first substrate) 4 and the power supply substrate (second substrate) 5 are horizontally disposed at substantially the same height at a predetermined interval behind the housing 1. The relay board 7 connected to the board 4 via the cable 6 is erected on the power supply board 5 via the connectors 8 and 9 so that the cable 6 gets over the relay board 7 and is wired in a substantially U shape. The cable 6 and the connector 8
, 9, the AV substrate 4 and the power supply substrate 5 are connected.

As shown in FIG. 5, the relay board 7 is formed integrally with the AV board 4 so as to be separable via a connecting portion 12 between a plurality of cuts 11, and by dividing the connecting portion 12, Separated from the AV substrate 4.

Corresponding to a large number of pins 6a projecting from both ends of the cable 6, a large number of pin holes 13 are formed in the inner edge 4a of the AV board 4 and the inner edge 7a of the relay board 7 facing each other with the cut 11 therebetween.
, 14 is formed to form a pair of linear pin hole rows 13A, 14A parallel to each other, and a connector 8 is provided along the outer edge 7b of the relay board 7.

Conventionally, the connection procedure between the AV board 4 and the power supply board 5 has been described in Patent Document 1 and the like, and an example thereof will be described. As shown in FIG. The cable 6 is gripped by a finger, and the pins 6a protruding from both ends of the cable 6 are manually inserted into the pin holes 13 and 14 of the pin hole rows 13A and 14A [FIG. 5 (b)].

Subsequently, the pins 6a of the cable 6 are soldered to the lands of the boards 4 and 7 by immersing the lower surfaces of the boards 4 and 7 with the cable 6 in a solder solution in a dip tank (not shown).

After that, as shown in FIG. 5 (c), the relay board 7 is gripped by the fingers and a load F is applied downward, so that the connecting part 12 is divided to separate the relay board 7 from the AV board 4, The relay board 7 is raised so that its inner edge 7 a enters the cable 6, and the connector 8 of the relay board 7 is fitted to the connector 9 of the power supply board 5, so that the relay board 7 is placed on the power supply board 5. Stand up [see FIG. 4 (b)]. As a result, the cable 6 gets over the relay board 7 and is wired in a substantially U shape.
JP 58-194394 A

In the above configuration, as shown in FIG. 4B, the cable 6 is routed over the relay board 7 in a substantially U shape, so that the height t1 of the cable 6 is higher than the height t2 of the relay board 7. Since the cable 6 is set large and the cable 6 is close to the top plate portion 1a of the housing 1, noise may be transferred from the top plate portion 1a to the cable 6 to adversely affect the reproduced video.

Therefore, for safety standards, it is required to secure a distance h between the top plate portion 1a of the housing 1 and the cable 6 at a certain value or more. In this case, the distance h (for example, 5 mm) and the cable 6 Because the total width (h + t1) with the height t1 (for example, 35 mm) becomes large (for example, 40 mm)
In design, this is a major obstacle when the height H of the housing 1 is reduced to reduce the thickness of the disk device.

Further, since the finger 6 is inserted between both ends of the cable 6 and the cable 6 is manually mounted, the distance L between the pin hole rows 13A and 14A needs to be relatively large, for example, about 10 to 20 mm. Yes (see FIG. 5A), and in addition to this, since the cable 6 is wired in a substantially U-shaped curve (see FIG. 5C), the cable 6 becomes long. Cost increases. Furthermore, since the connector 8 on the relay board 7 is arranged outside the cable 6,
The lateral width K of the relay substrate 7 is increased (see FIG. 5B), which also increases the cost.

The present invention has been made in view of the above-mentioned conventional drawbacks, and an object of the present invention is to provide a substrate connecting apparatus that can be made thin at low cost.
