[0002]

[Prior art]

 Generally, as a supporting tool for attaching the vehicle antenna to a part of the vehicle, there is, for example, one shown in FIG. Here, 11 is a coaxial cable, 18 is a mounting member that is attached to a part of the vehicle body by using a magnet or a suction cup, 19 is a coaxial connector, and 20 is a terminal portion of the antenna.

Then, the terminal portion 20 is fitted into the coaxial connector 19 to integrate them, and the coaxial connector 11 is passed through the tubular portion 22 attached to the outer peripheral surface side of the coaxial connector 19 by welding or the like, and then the connector is inserted. By connecting to the portion 21, the terminal portion 20 and the coaxial cable 11 are brought into conduction (see FIG. 4).

Conventionally, an L-shaped connector having such a tubular portion 22 is often used as the coaxial connector 19, and in this L-shaped connector, as shown in FIG. 4, the tubular connector 22 is connected to the coaxial connector. The coaxial cable 11 in the portion entering 19 is bent at a substantially right angle to form a bent portion 23.

It should be noted that although the type of the connector portion 21 shown in the drawing is an M type, an L type coaxial terminal having various types of standardized connector portions 21 such as N type, BNC type or TNC type is also used. The bent portion 23 is similarly generated in the connector.

[0006]

[Problems to be solved by the device]

 As described above, the conventional coaxial connector 19 has an integral structure as a whole and does not have a structure in which a part thereof can be bent, so that the coaxial connector to which the vehicle antenna is connected is connected to the vehicle body through the mounting member. If the mounting member has a structure such as the mounting member 18 shown in Fig. 3 that cannot be bent, rotated, etc. with respect to the vehicle, such as when it is mounted on a part, change the direction of the antenna. However, there was a problem that the antenna part got in the way, especially when the vehicle was put in the garage.

Further, as shown in FIG. 4, a bent portion 23 is formed in the coaxial cable 11 in the conventional L-shaped coaxial connector 19, and in this portion, the distance between the inner conductor and the outer conductor is different. Since it deviates from the distance in the linear part, the impedance at this bent part 23 becomes a value different from the characteristic impedance of the line, the integrity of the coaxial cable 11 is lost, and the signal is ensured. There is a problem that it cannot be communicated to.

Further, at the time of manufacturing the coaxial connector 19, after the coaxial cable 11 is passed through the tubular portion 22 and bent into an L-shape, work such as soldering with the connector portion 21 is performed. However, the work is not easy, and rain or the like enters the inside of the coaxial connector 19 through gaps such as cracks caused by damage or deterioration of the welded part 24, and deteriorates the metal part, which is not waterproof. It was

In view of this, in the present invention, the coaxial connector is divided into rotatably integrated units, and the mounting member to which the coaxial connector is attached is connected to the connector portion of the coaxial connector without rotating. For example, it is possible to change the orientation of a vehicle antenna, etc., ensure reliable transmission of signals by preventing excessive bending of the coaxial cable inside the coaxial connector, and facilitate manufacturing. It is an object of the present invention to provide a folding coaxial connector that can maintain waterproofness.
