Is composed of a terminal storage hole 2a 'and an insulating housing mounting portion 2b' for mounting on a printed wiring board. In the terminal holding hole 2a 'of the insulating housing 2',
The conductive terminal 3 'is inserted and held by press fitting.
The conductive terminal 3 'includes a contact portion 3a' for contacting a terminal of a mating connector (not shown), a terminal exposed portion 3b 'from the insulating housing, and a soldered portion 3c' for a printed wiring board. , A plurality of them are arranged on the left and right. The contact portion 3a 'of each conductive terminal 3' is in spring contact with the terminal of the mating connector and is electrically conductive. Terminal exposed part 3
b 'is partially exposed from the insulating housing 2', is bent in the direction of connection with the printed wiring board, and is aligned by the alignment plate 4 'so as to be equal to the through-hole pitch of the printed wiring board. Further, for the conductive terminals 3 ', terminal soldering portions 3c' are inserted into through holes of the printed wiring board,
Soldered and connected to the printed wiring board. In the conventional connector 1 ' constructed as described above, since there is a part of the terminal exposed portion 3b' from the housing, the impedance is inevitably increased, and when a high-speed electric signal flows, the signal between the printed wiring board and the connector is transmitted. There is a drawback that not only reflection occurs and reflection noise occurs, but also the influence between adjacent terminals is large and characteristics such as crosstalk deteriorate. In order to reduce the reflection noise due to the impedance mismatch, for example, a method of making the impedance of the connector close to the impedance of the printed wiring board by surrounding the signal terminal with the ground terminal and taking a pseudo coaxial structure is adopted. There is also. At the same time, since a shielding effect by the ground terminal can be expected, crosstalk can be suppressed. However, even in the connector having the pseudo coaxial structure as described above, if the ratio of signal to ground is 1: 1, a connector having twice as many poles as the number of signal terminals is required, and not only is the outer shape inevitably increased, but also the connector becomes larger. In addition, since the printed wiring board needs to be designed in consideration of the arrangement of the signal terminals and the ground terminals of the connector, there is a drawback that the design is restricted.

As is apparent from the figure, the conductive terminals 3 of the high-speed transmission connector 1 of the present invention are fixed by soldering the terminal soldering portions 3c to through holes of the printed wiring board 8, and are connected to the circuit of the printed wiring board. Is done. The comb-shaped cover 5 made of a conductive resin is fixed to the through hole of the printed wiring board by inserting the fixing metal 9 into the mounting hole of the cover mounting portion 5a, passing through the mounting hole of the housing mounting portion 2b of the connector.
