Since the signal core wire 2 is inserted into the through hole 14 of the printed wiring board 7 and electrically and mechanically connected and fixed to each other via the solder 15, the electric signal is transmitted from the connector 1 side to the printed wiring board. When it is transmitted to the 7 side, it is transmitted from the signal core wire 2 to the through hole 14 via the solder 15.

However, the diameter d1 of the signal core wire 2 is
Since it is shorter than the outer diameter d2 of the through hole 14, the transmission cross-sectional area of the electrical signal changes abruptly between the signal core wire 2 and the through hole 14. Therefore, the electric signal is transmitted to the signal core wire 2
The characteristic impedance abruptly fluctuates when it is transmitted from the solder to the through hole 14 through the solder 15,
There is a problem that the signal transmission efficiency deteriorates.

Further, when the signal core wire 2 is inserted into the through hole 14, the signal core wire 2 penetrates the through hole 14 and the tip of the signal core wire 2 pops out from the through hole 14 from the viewpoint of the insertion technique, and the signal core wire is inserted. 2 A step is formed between the tip and the signal wiring 16. Therefore, when the electric signal is transmitted from the signal core wire 2 to the signal wire 16, a reflection phenomenon is caused, which causes a problem that the signal transmission efficiency is deteriorated.

Further, as in the conventional case, when the signal core wire is connected to the signal wiring of the printed wiring board through the through hole, the signal layer 8 from the signal core wire 2 to the mounting surface side of each component of the printed wiring board 7 is provided. The signal wiring 1 which is once connected to the through hole 14 by the signal layer 15 to pull out the signal wiring to the
6, the signal core wire 2 must be connected, and the signal wire 16 must be routed through the VIA hole 17 formed in the printed wiring board 7, which causes a problem that the characteristic impedance fluctuates.
In this way, the VIA hole 17 must be provided because if the signal wiring is pulled out from the through hole 14 on the signal layer 8 side, interference occurs between the conductor 4 of the connector 1 and the signal layer 8.
