The socket 1 that each

terminal

3,4,5 is installed on the jack housing 2 is, when sleeve foot 37, substrate foot 44, ring foot 53 be configured on the face identical with the bottom surface of outer cover body 21, on the printed wiring board 60 that socket 1 is installed in as shown in Figure 3 the time, respectively with on printed wiring board 60, be relative ground connection figure, signal figure, the soldering of switch figure and connect.

The socket 1 that is installed on the printed wiring board 60 is, for example as shown in Figure 3, round buss 22 faced under the state of outside, is held to be installed between the base 10 and printed wiring board 60 that is grounded.

Install by this, than the plane of jack housing 2 more obliquely the outstanding base contact chip 36 in side be Elastic Contact in base 10, sleeve terminal 3 also can pass through base 10 ground connection except printed wiring board 60.

When the plug insertion 23 that plug 200 is inserted into the socket 1 of installation like this, and when being inserted in the plug insertion 23 fully to the position shown in 2 pecked lines of Fig. 1 and Fig. 2, sleeve contact tube portion 34 and loop contacts portion 52 Elastic Contact are electrically connected in grounding electrode 201, and substrate contact site 43 Elastic Contact are electrically connected in firewire electrode 202.

At this moment, the sleeve terminal 3 that is connected grounding electrode 201 is that base contact chip 36 is connected in base 10 because of sleeve foot 3 is connected in the ground connection figure, so, grounding electrode 201 and ground connection figure and base 10 earthing potential can be remained on, and the high-frequency noise of invading can be interdicted reliably from the outside.

In addition, loop contacts portion 52 is by being electrically connected with grounding electrode 201, and ring terminal 5 and become earthing potential by monitoring the variation of this current potential, comes the insertion of test plug 200.

Because sleeve terminal 3 is installed on the ground connection side shell 2A with ring terminal 5, so the integral body that has comprised sleeve foot 37, ring foot 53 does not exist around the axle of plug 200 firewire electrodes 202 that are inserted into.Therefore, these

terminal

3,5 and firewire electrode 202 between guaranteed sufficient distance, the high-frequency signals that flows into firewire electrode 202 can not spill, decay.

On the other hand, substrate terminal 4 is electrically connected in firewire electrode 202 high-frequency signals that flows by substrate contact site 43, but because of being installed on the hot side shell 2B, so comprised around the axle of grounding electrode 201 that there is not the plug 200 that is inserted in the integral body of substrate foot 44.Therefore, guaranteed sufficient distance between substrate terminal 4 and grounding electrode 201, the high-frequency signals that flow into substrate terminal 4 can not leak to grounding electrode 201 sides.

In this example, on jack housing 2, sleeve terminal 3 is installed, will encircle terminal 5 install from the below from the top, but sleeve terminal 3 and ring terminal 5 be as if being installed on the ground connection side shell 2A from the side with the direction of insertion quadrature of plug 200, its installation direction can be any direction.

Again, the shape of each terminal 3,4,5 is to cooperate its installation direction to make shape arbitrarily.

And also installing ring terminal 5 not also can be installed a plurality of ring terminals 5.

As mentioned above, adopt the invention of technical scheme 1, because of the sleeve terminal 3 that is connected the grounding electrode 201 of plug 200, with the substrate terminal 4 that is connected in firewire electrode 202 respectively can be not overlapping around axle, do not spill so between these, can not produce high-frequency signals, transmitting loss with not having being connected of plug.

Adopt the invention of technical scheme 2, can only socket 1 be installed in the base around being disposed at, sleeve terminal 3 is electrically connected on base 10.

Again, utilize base contact chip 36 Elastic Contact, on the base 10 around socket 1 can not be positioned at with rocking in base 10.

Because of the grounding electrode 201 of socket 200 is grounded on these two positions of printed wiring board 60 and base 2 by sleeve terminal 3, so, can be more effectively with plug 200 integral sealings.

Adopt the invention of technical scheme 3, though for the insertion of test plug installing ring terminal 5, and the firewire electrode 202 of plug 200 between can not spill high-frequency signals yet, and do not have and transmit loss, thereby plug 200 can be connected with socket 1.
