Accordingly, the plug signal inner wire becomes 12 in the Buchsensignalinnenleitung 22 inserted after the female inner shield 24 is widened, so it is possible to reduce the force required, the connector signal terminal 10 into the jack signal terminal 20 use. In addition, it is possible, the connector signal wire 12 to stop it from breaking.

In addition, as the shield of the terminal comes into contact state earlier than the signal terminal, the electrical circuit in this embodiment is further protected because the static electricity contained in the connector signal terminal 10 is charged, is released to the ground terminal, or the DUT is protected because the power supply sequence is fixed.

As above, each female signal will be internal 22 and female inner shielding 24 with each connector signal wire 12 and each connector inner wire shield 14 fitted. In addition, the connector signal terminals 10 safe electrically and mechanically with the jack signal connection terminals 20 connected.

Moreover, in this embodiment, the female inner lead shield is 24 designed so that the distance between it and the connector inner wire shield 14 gradually becomes wider from section AA to section BB. Accordingly, the female inner wire shield acts 24 with an elastic force. In terms of space for the operation, there is a gap where the insulator of the socket-side housing 60 , such as resin, is not filled between the plug inner wire shield 14 and female socket shielding 24 , In the same way, there is also a gap where the insulator such as resin is not filled between the connector signal inner wire 12 and the female bus signal line 22 , For this reason, the impedance value is at the mating surface of the connector signal terminal 10 and the jack signal terminal 20 with respect to the area of the section AA to the section BB larger than the impedance at the fitting surface of other sites filled with resin.

Because the groove of the circular extending portion 19 who is in contact with 8th has been described, the distance between the connector signal inner wire 12 and the connector inner wire shield 14 however, in this embodiment, the impedance decreases with respect to the connector signal terminal 10 corrected downwards. Because the groove of the semicircular extending portion 29 who is in contact with 13 has been described, the distance between the Buchsensignalinnenleitung 22 and female socket shielding 24 reduces, in the same way, the impedance with respect to the jack signal terminal 20 Accordingly, in this embodiment, it is possible to reduce the deterioration of the signal caused by impedance unevenness.

Although the connector signal terminal 10 in this embodiment, a male terminal is and the Buchsensignalanschlussklemme 20 is a female connector, can also have a side of the connector signal inner wire 12 and the connector inner wire shield 14 and the female bus signal line 22 and the female inner shield 24 alternatively, be a male terminal, whereas the other side thereof may be a female terminal.

18 shows another example of the configuration of the connector signal terminal 30 , 18 (a) shows an example of the configuration of the connector signal terminal 30 , 18 (b) shows an example of the configuration of the connector signal terminal 30 rotated 90 degrees about the axis direction.

In addition, the connector signal terminal 30 in this embodiment as the signal terminal 724 or the signal terminal 726 (please refer 4 ) used. In this case, the connection socket 300 as the connection part 702 or the connector part 710 used (see 4 ).

The connector signal wire 32 extends linearly, made of a conductor, such as metal. One end of the plug signal wire 32 leading to a coaxial cable 400 is electrically connected to the center conductor of the coaxial cable 400 connected. The coaxial cable is also referred to as the cable in this embodiment 706 (please refer 5 ) used. The middle conductor of the Koaxialka bels 400 can the transmission line 754 be (see 5 ).

The first shield 34 extends from the vicinity of the end of the plug signal inner wire 32 in the axis direction of the plug signal inner wire 32 , molded from a conductor that is electrically from the connector signal wire 32 is isolated and the connector signal wire 32 surrounds. The first shield 34 is received in a through hole whose diameter is approximately the same as the first shield 34 , formed in the plug-side housing.

The protruding section 36 stands in the direction away from the plug signal wire 32 off, from the end of the first shield 34 extend. Accordingly, the plug signal terminal becomes 30 locked on the surface of the plug-side housing. In this embodiment, the connector side housing includes a plurality of connector signal terminals 30 at the positions corresponding to the plurality of jack signal terminals 20 that in conjunction with 12 or 15 have been described.

The second shield 37 is made up of a conductor that is electrically connected to the connector signal wire 32 is insulated, extending from its end in the axial direction and the connector signal wire 32 surrounding. The end of the second shield 37 It's arranged that it's the first shielding 34 points, inserted between the connector signal wire 32 and the first shield 34 near the protruding section 36 , The other end of the second shield 37 is arranged so that it is the coaxial cable 400 points, electrically with the outer conductor of the coaxial cable 400 and the second shield 37 connected by soldering.

The plug-side connector configured as above may connect the plurality of plug signal terminals 30 properly grasp through the plug-side housing. Moreover, the plug-side connector properly handles the electrical signal between the plug-side connector and the coaxial cable 400 forward to fit together.

Even though the present invention by means of illustrative embodiments has been described, it should be understood that the expert many changes and substitutions, without departing from the spirit and scope of the present invention to depart, which is defined only by the appended claims.
