2. Description of the Related Art As a conventional two-piece connector for vertically connecting a board to a board, there is, for example, a connector comprising a pin connector 8 and a socket connector 9 which are fitted and connected to each other as shown in FIG. . This pin connector 8
Is an insulator 8 as shown in FIGS.
A large number of pin contacts 81 made of a conductive material are press-fitted and held. The pin contact 81 is formed at a lower end of the contact portion 81a that is fitted and connected to the mating contact (socket contact 91), an angle portion 81b formed integrally with the contact portion 81a, and a lower end of the angle portion 81b. Soldering portion 81 to be soldered to substrate B or the like
c. On the other hand, in the socket connector 9, a large number of socket contacts 91 made of a conductive material are press-fitted and held in the insulator 90. The socket contact 91 is disposed in the insulator 90, receives the contact portion 81a of the pin contact 81 and contacts the contact portion 81a, and a solder formed integrally with the contact portion 91a and protruding from the back surface of the insulator 90. Attachment portion 91c.

[0003]

In a two-piece connector of the type described above, the angle of the contact is long and the angle is exposed, and the contacts are parallel. When a high-frequency signal is transmitted, crosstalk noise is generated, which is one of the causes of malfunction or destruction of an electronic circuit of a device connected using this connector.

An object of the present invention is to provide a two-piece connector in which the occurrence of crosstalk is effectively prevented and the transmission characteristics of high-frequency signals are improved.

[0005]

According to the present invention, a first connector having a plurality of first contacts and a second connector having a plurality of second contacts respectively contacting the plurality of first contacts. A two-piece connector, wherein an angle portion is formed in one of the first contact and the second contact, and a connector having the other contact is provided with a first ground plate. A second ground plate, which is disposed between the plurality of contacts having the angle portion, blocks between the angle portions, and contacts the first ground plate.
A plurality of pairs are provided, and the second ground plate is
An isolating portion for interrupting the angle portion, which is in contact with the first ground plate.
A touching spring portion, and further comprising a second ground of each of said pairs.
In the plate, the spring portions face each other and the isolation portions are aligned.
A plurality of contacts having the angle portions so as to be arranged side by side
The two-piece connector is characterized by being arranged along the step direction .

[0006]

According to the present invention, since the second ground plate is disposed between the plurality of contacts having the angle portions, the angle portions of the contacts are cut off from each other, and the other connector is grounded from the ground plate of one connector to the other. A feedback current flows through the ground plane of the connector, and electromagnetic coupling between the signal contacts is reduced. As a result, crosstalk noise is reduced.
