A coaxial holding fitting 17 is provided facing the grounding fitting 16, and the coaxial wire 6 is tightened by both of these fittings 16, 17 and a tightening screw 18 that passes through the holding fitting 17 and is screwed into the grounding fitting 16. is designed to be fixed.

On the other side of the insulating base 8, a pair of feeder wire terminal fittings 19 are fixed and penetrated.

A balun transformer 2 is disposed between these terminal fittings 19 and the output coaxial plug 10.

The balun transformer 2 has a pair of input lines 2at2b and a pair of output lines 2c and 2d.The input line 2at2b is connected to each terminal fitting 19 by soldering, and one of the output lines 2c (
The balun transformer output line connecting portion 12D of the ri central conductor projecting portion 12B is connected by soldering, and the other output line 2d is connected to the ear portion 11A of the outer conductor 11 by soldering.

A tightening screw 20 is screwed into each terminal fitting 19, so that the conductor of the food wire 1+ can be fixed thereto.

An insulating cover 21 is placed on the front side of the insulating base 8.

A pair of locking claws 22 are protruded from these covers 21, insertion holes 23 into which these locking claws 22 are inserted are formed in the insulating base 8, and each of the locking claws 22 inserted into these insertion holes 23
is engaged with the stepped portion of the insulating base 8, whereby the cover 21
is fixed to the insulating base 8.

The push button 14 slidably passes through the cover 21 and is led out.

The electrical circuit configuration of such a two-man hook connector is shown in FIG. 8.

Next, how to use this two-man hook connector will be explained.

As shown in FIG. 7, the input coaxial line 6 is made by folding the braided outer conductor 6B around the outer periphery of the insulating coating 6C, peeling off the tip of the insulator 6D under the cut outer conductor 6B, and forming the central conductor 6A. expose.

The coaxial wire 6 is passed between the grounding fitting 16 and the coaxial holding fitting 17, and the push button 14 is pushed in so that the center conductor insertion hole 14B of the center conductor 12 is inserted into the center conductor insertion hole 12 of the center conductor 12.
C, and insert the center conductor 6A of the coaxial line 6 into these holes 14.
Insert into B and 12C.

When the pressing force on the push button 14 is removed, the push button 14 (Ii) is about to be pushed back by the spring 15, and the center conductor 6A is held between the push button 14 and the center conductor 12, and is electrically connected to the center conductor 12.

In this state, the coaxial line 6 is fixed by tightening the tightening screw 18.

The food wire 1 is matched by a balun transformer 2 and connected to an output coaxial plug 10.

As explained above, the two-man power hook connector according to the present invention has two types of input connectors integrated on the insulating base so that output can be output from a common output coaxial connector. It is possible to provide an input connector that can be used for both coaxial lines and 3008 series feeder lines.

In particular, with this connector, the coaxial line for manual use is fixed and its external conductor is electrically connected by tightening the grounding fitting and the coaxial holding fitting. This saves you the hassle of connection work.

Furthermore, since the center conductor of this coaxial line is connected using a push button, the connection can be easily made.
