A window 15 is formed in the insulator 13 at a position facing the bridge 21. Instead of molding into the insulator, contact parts 2 on the molded insulator
0 may be incorporated. After the signal contact 11 and the ground contact 12 are held by the insulator 13, the coupling portion 22 is separated from the carrier 23. In the work of holding the signal contact 11 and the ground contact 12 on the insulator 13, the work is handled as the integrally formed contact part 20, so that the number of parts is small and the work is easy.

Next, as shown in FIG. 7, the bridge portion 21 is cut off through the window portion 15, thereby disconnecting one end of the ground contact 11 from the signal contact 11. As a result, the portion 12a of the ground contact 12 and the portion 11a of the signal contact 11 adjacent thereto are
Exposed.

The joint 22 is also cut off. At this time, a portion of the ground contact 12 protruding downward from the insulator 13 is cut off. Thus, insulator 1
3, only the signal contacts 11 protrude.

Finally, the ground plate 16 is attached to a specific surface of the insulator 13. At this time, the contact spring 17 of the ground plate 16 is brought into contact with a part 12 a of the ground contact 12 through the window 15. As described above, the window portion 15 is used not only for separating the bridge portion 21 but also for electrically connecting the ground plate 16 and the ground contact 12.

Thus, the connector unit 5 is easily manufactured. According to the connector unit having this structure, coupling between signals is cut off at the right angle portion, and good crosstalk characteristics can be obtained.
