Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flex-rigid wiring board, and more particularly to a flex-rigid wiring board which allows for compact mounting of the flex-rigid wiring board.

[0002]

2. Description of the Related Art FIG. 3 shows an example of a conventional flex-rigid wiring board. FIG. 4 shows a process of mounting the flex-rigid wiring board on the device. A conventional flex-rigid wiring board is configured by connecting multiple rigid parts that are wired in an arbitrary pattern with a flexible cable that is wired in an arbitrary pattern, and the flexible cable is connected to the end surface of the rigid part. It was Therefore, when the flex-rigid wiring board is mounted in the housing of the device, the flexibility of the flexible cable has been a problem. For example, in the case of horizontally mounting a plurality of rigid portions connected by a flexible cable, it is necessary to have a certain amount of space outward from the end surface of the rigid portion to which the flexible cable is connected. Also, in order to reduce this space, if you try to bend the flexible cable slightly near the end face of the rigid part, the flexible cable pattern may be broken and the flexible cable pattern may be broken. Was especially noticeable.

[0003]

In the conventional flex-rigid wiring board, when the flex-rigid wiring board is mounted on the device, a certain space is required due to the flexibility of the flexible cable, which causes a problem that it cannot be mounted compactly. there were. In addition, when the flexible cable is bent from the end face of the rigid portion by ignoring the bendability with an unreasonable force, the connection reliability of the pattern of the flexible cable is affected.
The object of the present invention is to solve the above drawbacks, without impairing the connection reliability of the pattern of the flexible cable,
An object of the present invention is to provide a flex-rigid wiring board that can be compactly mounted in a narrow portion of the device.

[0004]

In order to achieve the above object, a flex-rigid wiring board according to the present invention has a plurality of rigid portions, and the rigid portions are connected in a circuit by a flexible cable. A cutout is provided in a part of a side edge of the plurality of rigid parts, the rigid parts are connected to each other by the flexible cable, and the flexible cable is connected to the rigid part. It is configured by providing a plurality of holes in the vicinity.

[0005]

According to the above construction, even if the flexible cable is bent with a small diameter, the connection reliability of the flexible cable is not impaired. Therefore, the rigid wiring board can be compactly stored in the device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail below with reference to the drawings. 1A and 1B show an embodiment of a flex-rigid wiring board according to the present invention. FIG. 1A is a plan view of the flex-rigid wiring board, and FIG. 1B is a sectional view taken along line AA of FIG. The flex-rigid wiring board 1 is composed of a rigid portion (A) of the flex-rigid wiring board 2, a rigid portion (B) 3 of the flex-rigid wiring board, and a flexible cable 4 connecting the both rigid portions.

The rigid portion (A) 2 of the flex-rigid wiring board has an arbitrary circuit pattern, and a part of this circuit pattern is connected to the pattern 6 of the flexible cable 4 of the flex-rigid wiring board. ing. The rigid portion (B) of the flex-rigid wiring board also has an arbitrary circuit pattern, and a part of this circuit pattern is connected to the pattern 6 of the flexible cable 4 of the flex-rigid wiring board. As a result, both the rigid portions (A) 2 and (B) 3 are electrically connected by the pattern 6 of the flexible cable 4. Also,
Flex rigid wiring board 1 both rigid parts (A) 2,
(B) 3 has a notch 7 in the end face portion to which the flexible cable 4 is connected.

The flexible cable 4 of the flex-rigid wiring board is provided with holes 5 in the end face of the cutout portion 7 connected to the rigid portion of the flex-rigid wiring board, avoiding the pattern of the flexible cable 4. Due to the holes 5 on the flexible cable 4, the flexible cable 4 is partially broken, and the flexibility of the flexible cable is improved as compared with the case where the entire surface is a flexible cable.

Next, a case where the flex-rigid wiring board is mounted in the apparatus housing will be described with reference to FIG. In this embodiment, both rigid parts (A) 2 and (B) 3 of the flex-rigid wiring board 1 are mounted horizontally. By fixing the rigid portion (A) 2 of the flex-rigid wiring board 1 and bending the flexible cable 4, the rigid portion (B) 3 of the flex-rigid wiring board is moved so as to be horizontal to the rigid portion (A). In this case, the flexible cable 4 bends around the end surface of the cutout portion 7 of the flex-rigid wiring board. There is a hole 5 in the flexible cable 4 on the end face of the cutout portion 7 of the flex-rigid wiring board, and the hole 5 allows easy bending.

In this way, the flexible cable 4 has the rigid portion (A) 2 of the flex-rigid wiring board.
It is bent around the notch 7 of (B) 3 and is connected inside the rigid parts (A) 2 and (B) 3 of the flex-rigid wiring board. Therefore, the flex-rigid wiring board 1 can be mounted without considering the bending dimension of the flex-rigid wiring board when the flex-rigid wiring board 1 is mounted in the apparatus housing, and the flex-rigid wiring board can be mounted in a compact form.

[0011]

As described above, according to the present invention, a part of a rigid portion of a flex-rigid wiring board is cut out, a flexible cable is connected from the cutout portion, and a plurality of holes are formed in a bent portion of the flexible cable. Therefore, without sacrificing the connection reliability of the flexible cable,
There is an effect that the flexible cable can be bent and the flex-rigid wiring board can be compactly mounted on the device.
