DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, there is shown a plug connector 1 which is a multi-pole connector, and a receptacle connector 2 fitted and connected to the plug connector 1 in a first direction A1 as shown by a white arrow. I have. The receptacle connector 2 is mounted on a so-called motherboard (not shown), and has an insulator 3 holding a large number of pin terminals 4 in a matrix.

The plug connector 1 will be described with reference to FIG. 2 in addition to FIG.

The plug connector 1 is mounted on a so-called daughter board (not shown) which is arranged orthogonal to the motherboard. The plug connector 1 includes a plurality of substantially plate-shaped connector units 5 stacked in a second direction A2 orthogonal to the first direction A1, and a metal shield plate 6 and an insulating member engaged therewith. It is integrated with the housing 7. Although two connector units 5 are shown in FIG. 2, actually, the receptacle connector 2
Are used depending on the arrangement of the pin contacts 4.

Referring to FIG. 3 in addition to FIG. 2, connector unit 5 as a connector according to the embodiment of the present invention.
Will be described. Each of the connector units 5 includes a plurality of signal contacts 11 arranged on a predetermined plane extending in a third direction A3 and a first direction A1 which are both orthogonal to the first direction A1 and the second direction A2. And a ground contact 12 disposed between the signal contacts 11. Signal contact 11 and ground contact 1
2 are conductive, and the insulators 13
And is bent at a right angle inside the insulator 13. The signal contact 11 has at one end a socket terminal 14 protruding forward from the insulator 13 in the first direction A1.

The insulator 13 has a window 15 at a position corresponding to the end of the ground contact 12. Therefore, the end of the ground contact 12 is exposed to the window 15. Further, a part of the signal contact 11 adjacent to both sides of the ground contact 12 is also exposed to the window 15. This meaning will be made clear later.

Further, a metal ground plate 16 is attached to one surface of the insulator 13 in the second direction A2, that is, a specific surface. The ground plate 16 is a substantially rectangular one formed by pressing, and is shown in FIG.
As shown in (a) and (b), a plurality of contact springs 17 that are in one-to-one correspondence with the ends of the ground contacts 12 through the window 15 and the first contact than the insulator 13.
, A plurality of contact pieces 18 protruding forward in the direction A1, and a plurality of terminal portions 19 connected to a ground (not shown) of a daughter board as a substrate.

The insulator 13 has engaging projections 13a and 13b formed on the rear surface and the upper surface, respectively. These engaging projections 13a, 13b are engaged with the engaging holes 6a, 6b formed in the shield plate 6 when integrating the plurality of connector units 5. That is, the engagement holes 6a and 6b of the shield plate 6 are
And the press-fit portions 6c of the shield plate 6 are press-fitted into press-fit holes (not shown) of the housing 7. At this time, the socket terminal 14 of the signal contact 11 and the contact piece 18 of the ground plate 16
And the terminal insertion hole 7a of the housing 7 and the contact piece insertion hole 7
and b respectively.

A method of manufacturing the connector unit 5 will be described with reference to FIGS.

First, a contact component 20 shown in FIG. 5 is prepared. This contact component 20 is formed integrally by applying a pressing process to a metal plate, and includes a plurality of signal contacts 11 arranged on one plane, a ground contact 12 disposed therebetween, and a ground contact 12.
And a connecting portion 22 in which the other end of the ground contact 12 and the other end of the signal contact 12 are connected to each other. The coupling part 22 is connected to the carrier 23.

Next, as shown in FIG. 6, the signal contact 11 and the ground contact 12 are connected to the insulator 13.
And hold it. When molding in,
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.
