2. Description of the Related Art Conventionally, as shown in FIG.
When the circuit board 2 on the main body 11 and the circuit board on the lid 12 are electrically connected to each other in a small device 10 such as a mobile phone which is configured to be rotatable around a hinge shaft 13, the lead wire is formed of a hinge part. It was going through the inside. However, this lead wire insertion work hinders automatic assembling and causes a reduction in work efficiency.

[0003]

Therefore, by using a connector having the above-mentioned body and a contact fitting and a lead wire electrically connected to the fitting, it is easy to assemble it into a small device and to assemble it easily. Considering the electrical connection between the contact fittings and the lead wires, the workability is poor due to crimping and soldering, resulting in a reduction in production efficiency, and because it is difficult to miniaturize, connectors used for small devices such as mobile phones. Therefore, electrical connection by pressure welding is preferable. However, in general, in the case of press contact, the insertion direction of the contact fitting is orthogonal to the longitudinal direction of the lead wire, so that the body is accommodated in the hinge part, and the rotation axis along the insertion direction of the contact fitting with the rotation of the hinge part. If the lead wire is rotated around, the extension of the lead wire will rotate greatly, so if the tip of the lead wire is fixed to another circuit board by soldering, etc., the lead wire will be excessively bent or pulled and will break. There is a possibility that the rotation of the hinge portion may be hindered by the lead wire.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object the object of being easy to assemble, having a small body, and being accommodated in a hinge portion of a small device such as a portable telephone, and rotating the hinge portion. Accordingly, it is an object of the present invention to provide a highly reliable connector in which a lead wire is not excessively bent or pulled and does not easily break even when rotated around a rotation axis along a direction in which a contact fitting is inserted.
