DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone, and more particularly, to a structure of a foldable portable telephone having a built-in RF cable.

[0002]

2. Description of the Related Art A conventional portable telephone will be described with reference to the drawings.

FIG. 3 is a perspective view showing a first example of a conventional portable telephone.

Referring to FIG. 3, a first conventional mobile phone has a structure in which a vehicle-mounted antenna connector 14 and an external control connector 13 are mounted on separate housings.

[0005] In this first example, the vehicle-mounted antenna connector 14 and the radio unit 11 are directly connected, and the external control connector 13 is directly connected to the control unit 6.
a, the connector mounted on the lower housing 3a is a closed connection between the radio unit 11 and the control unit 6 housed in the respective housings.

FIG. 4 is a perspective view showing a second example of a conventional portable telephone, and FIG. 5 is a sectional view of a hinge portion thereof.

A second example shown in FIG. 4 has a structure in which a connector for an in-vehicle antenna and a connector for external control are mounted on the same lower housing 3b, and an RF cable (high-frequency coaxial cable)
This is an example in which upper and lower housings are connected to each other with built-in 4b and 5b.

In the second example, a foldable mobile phone having a structure in which upper and lower housings are connected to each other, that is, an upper housing 12b for housing a receiver and a lower housing 3b for housing a transmitter and the like are connected by RF cables 4b and 5b. In case of telephone, RF cable 4
b and 5B are hinge portions 8 which are folding portions of the upper and lower housings.
b in the folding direction, so that the RF cables 4b, 5b
b is configured to apply a load to bend in the same direction as the folding at the portion located at the hinge portion 8b.

In FIG. 5, the RF cables 4b, 5b are connected straight from the lower housing 3b to the upper housing 12b at right angles to the hinge portion 8b.

[0010]

In the portable telephone of the first conventional example, a connector for an in-vehicle antenna and a connector for external control are mounted on separate housings, respectively, and an in-vehicle adapter is mounted on the portable telephone of the first example. When connecting to a telephone, there are problems that not only are there two connector connection points, but also the external dimensions of the vehicle-mounted adapter must be increased in order to realize the connector connection.

In the second prior art portable telephone, the in-vehicle antenna connector and the external control connector 5 are mounted on the same housing, but the RF cable is connected between the housings. , A load (force) is applied to the insulating cover and the core wire each time the mobile phone of the second example is folded in the same direction as the folding direction, and as a result, the cable jacket is broken, the cable core wire is broken, and the like. However, there is a problem that the risk of an accident concerning the connection of the RF cable between the housings is extremely high.

[0012]

A portable telephone according to the present invention comprises:
In a foldable mobile phone in which the in-vehicle antenna connector and the external control connector are individually or integrally mounted on the same housing, the wireless unit is on a separate housing from the in-vehicle antenna connector, An RF cable connecting the radio unit and the on-vehicle antenna connector passes through the hinge in a direction parallel to a bending direction of each housing, and is bent in a crank shape.

[0013]

Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing one embodiment of the present invention, and FIG. 2 is a sectional view of a hinge portion in the present embodiment.

In FIG. 1 and FIG. 2, in the present embodiment, a vehicle-mounted antenna / external control unit integrated connector 1 is arranged in a lower housing 3, control signals are transmitted to a control unit 6, and RF cables 4 and 5 are passed through the lower housing 3. It is connected to the wireless section 11 of the upper housing 12.
The hinge portion 8 has a structure in which the RF cables 4 and 5 penetrate in a crank shape in a direction parallel to the folding of the housing.

As a result, accidents related to connection such as disconnection of the cable and poor contact due to changing the load in the folding direction of the RF cables 4 and 5 for each folding to the twisting direction are prevented.

[0017]

As described above, according to the present invention, it is possible to control the load applied to the RF cable by penetrating the RF cable hinge in a direction parallel to the folding of the housing and bending it in a crank shape. Therefore, disconnection from the RF cable can be prevented, the connector for the vehicle-mounted antenna and the external control connector can be mounted on the same housing, and the flip-type mobile phone excellent in space factor when the vehicle-mounted adapter is connected. Can be provided.
