Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a substrate connection method, and more particularly to a connection device between flexible printed circuit boards.
[0002]
[Prior art]
Conventionally, when connecting flexible printed boards, it has been necessary to connect through, for example, slit-like holes in the camera body. In this case, the width of the flexible printed circuit board is narrowed to be equal to or smaller than the width of the slit hole.
[0003]
[Problems to be solved by the invention]
However, if the width of the flexible printed board is narrowed to be equal to or smaller than the width of the slit hole, there is a problem that reliability at the connecting portion of the flexible printed board is lacking because there are few electrical contacts.
[0004]
In view of the above points, an object of the present invention is to provide a method for manufacturing a device that can pass through a thin slit and realizes a connection with a large area of electrical contact.
[0005]
[Means for Solving the Problems]
This onset Ming, a member having a hole extending through the contact group is provided for performing other electrical substrate electrically connected to a flexible printed having a large contact group portion dimension than the opening of said holes In a manufacturing method of a device comprising a substrate, the contact group portion is passed through the hole portion in a state of being bent between the contacts of the contact group of the flexible printed circuit board, and the contact group portion that has passed through the hole portion is passed through the hole portion. The flexible printed circuit board and the other electric circuit board are electrically connected via the contact group .

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0009]
FIG. 1 is a view of the camera body as viewed from the back with the back cover opened. As shown in FIG. 1, a slit 12 is provided in the main body rear cover 11 of the camera main body 10. As shown in FIG. 2, the rear cover 15 of the camera is provided with a substrate 16 including a liquid crystal unit for displaying the date and the like, and a pressure plate 14 covering the substrate 16, and from the substrate 16 to the substrate 16. A flexible substrate 13 electrically connected to the substrate extends. The flexible substrate 13 is inserted into the slit 12 and is electrically connected to the camera body 10, but a contact point electrically connected to the flexible substrate 13 is used for improving reliability. Since it is wide, it cannot be inserted into the slit 12 as it is.
[0010]
Next, FIG. 3 is an enlarged view of the distal end portion (portion surrounded by a dotted line) of the flexible substrate 13 shown in FIG. As shown in FIG. 3, the tip of the flexible substrate 13 is wider than parts other than the tip. The inside of the cover lay opening indicated by a circle at the tip of the flexible substrate 13 is an electrical contact, and the electrode is exposed. Further, the flexible substrate 13 can be folded back along a break line running beside the tip of the flexible substrate 13.
[0011]
FIG. 4 is a view showing a case where the distal end portion of the flexible substrate 13 is bent along the breaking line of the bending and inserted into the slit 12. As shown in FIG. 4, the flexible substrate 13 has its tip end folded back according to the breaking line of the bend, so that the width becomes narrower than that of the slit 12 and can be inserted.
[0012]
Next, in FIG. 5, after inserting the flexible substrate 13 into the slit 12, the distal end portion of the flexible substrate 13 is expanded according to the breaking line and connected to another flexible substrate 17 in the camera body 10. It is the figure which showed the case. As shown in FIG. 5, since the area of the connection portion indicated by the dotted line between the flexible substrate 13 and the flexible substrate 17 is larger than the width of the flexible substrate other than the tip portion, the connection should be made more reliably. Can do.
[0013]
Next, FIG. 6 is a cross-sectional view of a connection portion indicated by a dotted line in FIG. As shown in FIG. 6, an elastic member 18 such as rubber is installed between the camera body 10 and the flexible substrate 13, and another flexible substrate 17 is disposed on the flexible substrate 13. Similarly, an elastic member 18 is installed. Further, a washer 19 is installed on the elastic member 18 installed on the other flexible substrate 17, and finally fixed with screws 15. The main body rear cover 11 is covered from above.
[0014]
Next, FIG. 7 is an enlarged view when the distal end portion of the flexible substrate 13 is developed after the flexible substrate 13 is inserted into the slit 12. As shown in FIG. 7, the flexible substrate 13 bent to be narrower than the slit 12 is inserted into the slit 12, and after passing, the bent tip portion is developed according to the breaking line. At this time, it is desirable that the area does not protrude beyond the main body rear cover 11.
[0015]
Figure 8 is a diagram showing a relationship between the bending line of the flexible substrate 13 (one point chain line in FIG. 8) and the conductive pattern. As shown in FIG. 8, it is desirable not to form a conductive pattern on both sides of the fold line (width α in FIG. 8) in the cover lay opening indicated by the circle where the electrical contacts are exposed.
[0016]
FIG. 9 is a view showing a flexible substrate 21 in which the tip of the flexible substrate 13 is another conductive pattern. As shown in FIG. 9, even in the case of such a conductive pattern, it is desirable not to form a conductive pattern on both sides of the fold line (width β in FIG. 9). The conductive pattern on the right side of the vertical dotted line in FIG. 9 is the cover lay opening where the electrical contact is exposed.
[0017]
Next, FIG. 10 is a view showing a flexible substrate 22 in which the tip of the flexible substrate 13 is another conductive pattern. In the case of this flexible substrate 22, it is bent at two places so that the tip portion is narrower than the width of the slit 12, but in this case as well, it is desirable not to form a conductive pattern on both sides of the folding line. Note that the conductive pattern on the right side of the vertical dotted line in FIG. 10 is the cover lay opening where the electrical contact is exposed.
[0018]
Next, FIG. 11 is a diagram showing a flexible substrate 23 in which the tip of the flexible substrate 13 is another conductive pattern. In the case of this flexible substrate 23, the tip portion is narrower than the width of the slit 12, and the slit 12 is allowed to pass through in this state. Then, after passing through the slit 12, the connection is performed by bending in two places in the vertical direction (A) and the horizontal direction (B). FIG. 12 shows a state where the flexible substrate 23 is bent.
[0019]
Next, FIG. 13 is a diagram showing a flexible substrate 24 in which the tip of the flexible substrate 13 is another conductive pattern. In the case of this flexible substrate 24, the entire flexible substrate 24 is bent at the breaking line in FIG. 13 is expanded after the slit 12 is inserted, and is used as an electrical connection (communication line) with an external device, for example, by pasting it on the wall of the battery chamber. To do.
