Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile phone, and more particularly to a mobile phone having a folding structure.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 3, a mobile phone of this type has a first casing 6 having an antenna 14 and a receiver 15, a second transmitter 16 and a dial button 17.
The housing 7 is connected to the housing 7 by a hinge portion 11, a wireless circuit is mounted in the first housing 6, and a control circuit is mounted in the second housing 7. For connection of electric signals between the first and second housings 6 and 7, the flexible substrate 8 is passed through a slit-shaped hole provided in the central portion of the hinge portion 11, and in addition, in the mobile phone of this conventional example. As an interface with the outside,
For example, the connectors 12 and 13 for supplying power in the automobile and connecting to the on-vehicle antenna are provided on the side surface 10 of the second housing 7 and the side surface 9 of the first housing 6, respectively.

[0003]

In this conventional portable telephone, since the electric signal connector and the antenna signal connector are separately provided in the first and second housings, it is not only troublesome to connect the in-vehicle adapter or the like. However, there is a problem in that the processing of the connecting cable and the like becomes an obstacle and the usability becomes poor.

[0004]

The mobile phone of the present invention comprises:
A mobile phone in which a first housing including an antenna and a receiver and a second housing including a transmitter are configured to be foldable by mutually rotating about a hinge portion, and a side surface of the second housing. Is provided with a first connection portion for receiving signals and power from the outside and a second connection portion for receiving antenna signals from the outside, and a central portion of the hinge portion is formed into a cavity, A flexible board for transmitting electric power and electric signals between respective circuits in the second housing is wound around the inner diameter of the cavity to pass therethrough, and a coaxial cable connected to the second connecting portion is connected to the flexible board. It is connected to the antenna by passing through the inside of the winding and extending along the flexible substrate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is an exploded view showing the structure of a hinge portion of this embodiment.

Referring to FIGS. 1 and 2, this mobile phone includes a first housing 1 having an antenna 14 and a receiver 15.
And a connector 5b for receiving signals and electric power from the outside, a connector 5b for receiving antenna signals from the outside, and the transmitter 1.
The second housing 2 including 6 and the dial button 17,
The hinge portions 1-3 and 2-3 are rotatable around each other and can be folded.

The first casing 1 and the second casing 2 are composed of front cases 1-1 and 2-1 and rear covers 1-2 and 2-2, respectively, and both ends of the front cases 1-1 and 2-1. Both parts are rotatably fastened by hinge parts 1-3 and 2-3 provided on the part. In the central part, the hinge parts 1-3 and 2
-3 is provided with hinge semi-circular portions 1-4 and 2-4 of the receiving portion that form an approximately semi-circle of the shaft diameter, and the remaining semi-circular hinge semi-circular portion 1
By covering the rear covers 1-2 and 2-2 formed with -5 and 2-5, the appearance as one axis is achieved.

A flexible substrate 3 for transmitting electric signals of the circuit parts mounted on the first housing 1 and the second housing 2 is provided on the hinge semicircular portions 1-5 and 2-5 at the center of the hinge semicircular portion. From the outside by passing the coaxial cable 4 configured to make one turn along the inner diameter of 1-5, 2-5 and transmitting an antenna signal from the outside through the central portion of the winding diameter of the flexible substrate 3 in a substantially Z shape. Both the electric power and the electric signal and the antenna signal are collected on the same side surface of the second housing 2 with the connection portion 5a and the connector 5b of the external interface.

Since the flexible substrate 3 is housed in a single turn, the tension and slack in folding can be absorbed in the hinge semicircular portions 1-4 and 2-4, and the twist of the coaxial cable 4 can be absorbed. . Further, the coaxial cable 4 is required to have a certain degree of curvature in order to ensure the reliability of the bent portion, but the bending radius having a margin with respect to the hinge shaft diameter is given by adopting a structure in which the central portion of the flexible substrate 3 is passed. .

Although not shown, the other end of the coaxial cable 4 is connected to the fixed portion of the antenna 14.

[0012]

As described above, according to the present invention, the first casing having the antenna and the receiver and the second casing having the transmitter are provided.
In a mobile phone configured such that the housing and the housing of the second housing are rotatable with respect to each other with a hinge portion as an axis and can be folded, a first connection portion for receiving signals and power from the outside and an antenna from the outside on a side surface of the second housing A second connection portion for signal reception is provided, a central portion of the hinge portion is formed in a cavity, and a flexible substrate for transmitting power and electric signals between each circuit in the first and second housings is provided in an inner diameter of the cavity. By making one turn along the flexible cable, the coaxial cable to be connected to the second connecting portion is connected to the antenna by passing through the diameter of one turn of the flexible substrate and extending along the flexible substrate. The interface can be integrated into the second housing. As a result, when used in combination with in-vehicle adapters and other options, the connection cable does not become complicated, so connection becomes easier,
The usability can be improved as compared with the conventional one.
