DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to FIGS. The same components as in the prior art are denoted by the same reference numerals and description thereof will be omitted.

FIG. 1 shows a coaxial cable connection device in which an antenna control board and a coaxial cable are communicably connected to each other. A ground 12 of the coaxial cable 1 is previously provided on the control board 11 by solder reflow. An earth pattern 13 for soldering is formed.
A live pattern 14 is formed on the inner side of the substrate 1 so as to be coaxial with the ground pattern 13 and separated from the ground pattern 13 by a predetermined distance toward the inner side of the substrate 11.

The ground pattern 13 is formed to extend linearly for a predetermined length in order to solder the ground 12 of the coaxial cable 1, while the live pattern 14 is formed.
Then, a live connector 16 for connecting the core wire 15 of the coaxial cable 1 is soldered.

The live connector 16 allows the core wire 15 of the coaxial cable 1 to be elastically inserted from the ground pattern 13 side, and is always in elastic contact with the outer peripheral surface of the core wire 15 with a predetermined resilient force so as to be electrically connected. In order to conduct electricity, a metal strip having a predetermined elasticity is bent to form a U-shape on the front end side which is narrower than the diameter of the core wire 15 and the rear end side is wider than the diameter of the core wire. The width of the connector 16,
That is, the width of the strip is set slightly larger than the diameter of the core wire 15.

In order to adjust the height position of the live connector 16, a support 17 is integrally provided on the front and rear of the lower surface of the live connector 16, and the live pattern is provided via the pair of supports 17. 14 is soldered.

The support base 17 is made of a plate material having good electrical conductivity, and the height thereof is set to the live connector 16 by the core wire 15.
The height is set to insert smoothly. For this reason, when the ground 12 is placed on one end of the ground pattern 13 and the end of the ground 12 faces in the extending direction of the ground pattern 13, the core wire 15 of the coaxial cable 1 faces the insertion port 18 of the live connector 16. When the coaxial cable 1 is slid from the ground pattern 13 to the live pattern 14 in this state, the core wire 15 is smoothly fitted to the live connector 16.

Further, as shown in FIG. 2, a pair of regulating plates 19, 19 for vertically guiding both side surfaces of the live connector 16 are attached to the control board 11 with the live pattern 14 as a center, and the live pattern is mounted on the control board 11. If the inclination of the connector 16 to the left and right is regulated and the torsion is regulated, the work of inserting the core wire 15 into the live connector 16 can be further facilitated. In this case, the pair of regulating plates 19, 19 are formed by resin molding, and the live connector 1
6 and the support bases 17 are integrally formed by press molding, and both ends of the pair of support bases 17 are buried in the regulating plates 19 at the same time as the resin molding to form an integral part. The live connector 16 can be locked to the board by forming an engaging / disengaging portion that is engaged and disengaged by both the regulating plates 1 and 17 and the control board 11, pins, holes, and claws (none of which are shown). Well, and as shown in FIG.
The upper ends of the pair of regulating plates 19 are connected to a connecting plate 20.
The connecting plate 20 is provided with a window 21 for allowing the live connector 16 to expand in a vertical direction.
The two sides are integrally joined to form an integral part. As described above, the engaging and disengaging portions which are engaged and disengaged by the control plates 1 and 17, the control board 11, the pins, the holes, and the claws (none of which are shown). With this configuration, the live connector 16 may be locked to the board. At that time, each component can be used as a single connector, so that the handling of the components is greatly improved, and the number of steps for mounting the components on the control board 11 is greatly reduced. .

As shown in FIG. 4A, a U-shaped grounding metal 2 is placed on the grounding pattern of the control board 11 in advance.
2 is soldered, and when grounded, Fig. 4 (B)
As shown in FIG.
After the earth 12 is inserted between 3, 23, FIG.
As shown in (1), both the flanges 23 may be bent inward to fix the earth 12 to the earth metal fitting 22.
At that time, it is possible to prevent the deterioration of the connection quality due to the fraying of the ground 12 as much as possible, and it is possible to improve the reliability of the entire connection device as much as possible.

As described above, the present invention can be variously modified without departing from the spirit of the present invention, and it is natural that the present invention covers the modified invention.
