Abstract

PROBLEM TO BE SOLVED: To obtain a communication unit in which wiring, securing and treatment of extra length of cables are performed easily and surely, labor required for wiring is reduced without increasing the parts cost and change of the cable diameter can be dealt with. SOLUTION: A cut 12 is made in a substrate 8 and a cable 2 is secured at the cut. Since the width of the cut 12 is larger than the diameter of the cable 2, the cable 2 is inserted easily into the cut 12 and fitted in a curved part 13 where the cable 2 is secured surely without being caught. Consequently, labor required for wiring the cable 2 is reduced and the cable 2 is not removed easily.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication device such as a wireless device, a portable wireless device, and a portable telephone having an electronic circuit board.

[0002]

2. Description of the Related Art A communication device has a wiring for an antenna, a wiring for a switch and a plug, and the like, and a cable for the wiring is routed in a case. Due to operational problems, the cable has the necessary extra length.

However, after the cable is connected, the extra length is fixed to an empty space of the case so that the extra length becomes a hindrance to the work, or a load is not applied to the connection portion.

With reference to FIGS. 3 and 4, a description will be given of wiring, fixing, and extra length processing of a cable, taking a portable wireless device 1 as an example of a conventional communication device.

The case 3 is a molded product made of plastic or the like, and a case (one not shown) divided into two
The parts are integrated by means such as screwing. Antennas 5 and 5 extend from the left and right sides of the case 3, and the antenna 5 is refractible.
Penetrates the side plate 4, is fixed inside the case 3 by screws, and the cable 2 is connected to the base end 6.

An electronic circuit board 8 is mounted inside the case 3, and the cable 2 is connected to the electronic circuit board 8 via a connector 9.

A plurality of ribs 11 (eight in the left and right directions in the conventional example) are provided on the inner bottom surface of the case 3 along the side plate 4. The rib 11 is formed integrally with the case 3 in advance assuming a wiring route of the cable 2. The rib 11 is located between the electronic circuit board 8 and the side plate 4, and the distance a and the diameter of the rib 11 are determined in consideration of the diameter of the cable 2, and the distance a is the distance of the cable 2. It is assumed that there is no looseness when the cable 11 is wound around the rib 11 in a zigzag manner, and no load is applied to the cable 2. The ribs 11 are usually provided as a set of three or more ribs.

The cable 2 is pushed between the ribs 11 and between the rib 11 and the side plate 4. The cable 2 is sandwiched between the ribs 11, and the excess length of the cable 2 is processed and fixed.

As another fixing method of the cable 2, although not shown, there is an example in which another part such as a cable clamp is used, and the cable 2 is fixed by the cable clamp, and the extra length of the cable 2 is processed. You.

[0010]

However, the cable 2
Is troublesome because the ribs 11 are located in a narrow place, and the number of wiring steps for the cable 2 is increased.

If the height of the ribs 11 is not sufficient, the cable 2 is likely to be detached, and the work must be restarted, or the detached cable 2 becomes unstable.

The arrangement interval of the rib 11 is the same as that of the cable 2.
Since it is integrally formed with the case 3 in accordance with the diameter of the cable, it is not possible to cope with a change in the diameter of the cable 2 or the like, which is not applicable.

Further, when another component such as the cable clamp is used for fixing the cable 2, there is a problem that the component cost is increased.

The present invention has been made in view of the above-mentioned circumstances, so that the wiring, fixing, and extra length processing of a cable can be easily and reliably performed, the number of wiring steps can be reduced without increasing the cost of parts, and the cable diameter can be changed. Is what you do.

[0015]

SUMMARY OF THE INVENTION The present invention relates to a communication device in which a notch is provided in a substrate and a cable is fixed in the notch.

Since the cable is easily inserted into the notch, the number of wiring steps is reduced. Since the cable is securely fixed by the cutout, the wiring of the cable and the extra length processing are easy. Since the cable is fixed by the notch regardless of the diameter, it is possible to cope with a change in the cable diameter.

[0017] If the shape of the cutout portion is L-shaped, the cable is caught by the bent portion, and is more difficult to be detached.

[0018]

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, the same components as those in FIGS. 3 and 4 are denoted by the same reference numerals.

This embodiment is an example in which a cable 2 from an antenna 5 is wired to an electronic circuit board 8 via a connector 9 in a portable wireless device 1 which is an example of a communication device.

The portable radio 1 has a case 3, and the antenna 5 is attached to a side plate 4 of the case 3.
A base end 6 of the antenna 5 penetrates through the side plate 4, the base end 6 is fixed inside the case 3 by screws, and the cable 2 is connected to the base end 6.

The electronic circuit board 8 is provided inside the case 3.
An L-shaped notch 12 is provided at a required position on an end of the electronic circuit board 8 on the side plate 4 side. The notch 12 is located at a non-wiring portion of the electronic circuit board 8, the width of the notch 12 is formed larger than the diameter of the cable 2, and the notch 12 has a bent portion 13.

The notch 1 in the electronic circuit board 8
The position of 2 is determined in consideration of the wiring route of the cable 2, and the cutout 12 is provided when the electronic circuit board 8 is formed.

A connector 9 is provided on the electronic circuit board 8, and the cable 2 is connected to the connector 9.

The operation will be described below.

The antenna 5 is mounted on the case 3, the cable 2 passes through the vicinity of the side plate 4 according to a predetermined wiring route, an intermediate portion of the cable 2 is inserted into the cutout 12, and the cable 2 Is fixed at the bent portion 13.

The cable 2 extends to the upper surface of the electronic circuit board 8 via the bent portion 13 and is connected to a connector 9.

Since the width of the notch 12 is larger than the diameter of the cable 2, the cable 2 is easily inserted into the notch 12, fitted into the bent portion 13, and inserted into the bent portion 1.
At 3, the cable 2 is hooked and securely fixed. Thus, the number of wiring steps for the cable 2 is reduced, and the cable 2 is not easily detached.

Since the notch 12 is provided on an optimum wiring route in consideration of the wiring and extra length processing of the cable 2, the extra length processing can be performed simply by inserting the cable 2 into the notch 12. The connection of the cable 2 is facilitated.

Since the notch 12 is formed integrally with the electronic circuit board 8, the cost of parts such as a conventional cable clamp is not required, and the processing cost does not increase.

The communication device of the present invention is not limited to the portable wireless device in the above-described embodiment, but can be applied to the processing of a cable extra length of any communication device. The present invention can be applied to various kinds of cables. Further, the shape of the cutout portion 12 may be an arc shape. Needless to say, the location and number of the cutout portion can be arbitrarily determined as necessary.

[0032]

As described above, according to the present invention, since the cable is fixed by the notch provided in the substrate, the cost of parts is not increased, and the cable can be easily and reliably connected and fixed. Extra processing is performed, the number of assembly steps is reduced, the assemblability is improved, and the cable diameter can be easily changed. When the notch is L-shaped,
Various excellent effects such as the cable being more securely fixed are exhibited.
