 The present invention relates to a board-to-board connector, and more particularly to a board-to-board connector with less crosstalk.

[0002]

[Prior art]

 5 (a), (b), and (c) are a top view, an AA sectional view, and a BB sectional view, respectively, showing a conventional inter-board connecting connector. 5 (a) to 5 (c), this connector has insulators 50 in which rows of contacts 60 of normal size and rows of wide contacts 70 are alternately provided in a zigzag arrangement. ing.

Compliant portions 61 and 71 are provided on the contacts 60 and 70, respectively, and are attached to the substrate 80.

Both of the contacts 60 and 70 are oriented in the width direction thereof in the longitudinal direction of the connector.

[0005]

[Problems to be solved by the device]

 When the normal contact 60 is used for signals and the wide contact 70 is used for ground among the contacts, as shown in FIG. 5A, the signal contacts 60 are adjacent to each other. It is surrounded and shielded by the ground contacts 70 of the row.

However, in the longitudinal direction of the connector, the plurality of signal contacts 60 are adjacent to each other and are not shielded by the ground contact 70, which is a cause of crosstalk. .

An object of the present invention is to provide a connector for board-to-board connection that has a high shielding effect and does not cause crosstalk.

[0008]

[Means for Solving the Problems]

 According to the present invention, in order to achieve the above-mentioned object, wide contacts having wide portions and normal contacts having a normal width are alternately arranged in an insulator, and the plate thickness direction of the wide contact is in the longitudinal direction of the connector. It is characterized in that the wide contacts surround at least three sides of the normal contacts.

Further, according to the present invention, a wide contact having a wide portion and a contact having a normal width are alternately arranged in the insulator, and the plate thickness direction of the wide contact is oriented in the longitudinal direction of the connector. And is arranged so that the plate thickness direction of the normal width contact is orthogonal to the plate thickness direction of the wide contact.

Further, in the present invention, the alternating rows of the wide contacts and the normal width contacts are two rows, and the wide contacts and the normal contacts are alternately arranged between adjacent alternating rows. Is characterized in that.

Further, according to the present invention, the alternating rows of the wide contacts and the normal contacts are three rows or more, and the wide contacts and the normal contacts are alternately arranged between adjacent alternating rows. It is characterized by being a thing.

[0012]

[Action]

 According to the present invention, by using the contact having the normal width for the signal and the wide contact for the ground, the normal contact is surrounded by the wide portion of the wide contact in at least three sides inside the insulator. , The shielding effect is enhanced.

Embodiments Hereinafter, a board-to-board connector according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 and FIG. 2 are perspective views showing an inter-board connecting connector and a mating connector according to this embodiment, and FIG. 3 is a cross-sectional view of a contact embedding portion of an insulator to be described later of this connector. Is. 1 to 3, the connector for board-to-board connection is configured such that two types of a normal contact 20 having a normal width and a wide contact 30 having a wide portion inside the insulator 10 are alternately arranged. The insulator 10 is fixedly held in two rows. In this case, the wide contact 30 is fixed and held with the plate thickness direction facing the longitudinal direction of the connector. Further, the normal contact 20 is fixed and held so that the plate thickness direction thereof is orthogonal to the plate thickness direction of the wide contact 30.

In FIG. 1, reference numeral 45 is a partner side connector that is fitted and connected to the inter-board connecting connector, in which contacts 46 and contacts 47 are contacts of the inter-board connecting connector. 20 and contacts 30 are provided. Then, as shown in FIG. 2, when the mating connector 45 is fitted into the insulator 10 of the present connector, the contact 46 is connected to the contact 20 and the contact 47 is connected to the contact 30, and the circuit of the substrate 35 is connected. And the circuit of the substrate 40 are connected.

In FIG. 3, in the insulator 10, the wide portion of the wide contact 30 surrounds the normal contact 20 on three sides. When the normal contact 20 is a signal contact and the wide contact 30 is a ground contact, the ground contact surrounds three sides of the signal contact.

The connection between the contacts 20 and 30 and the substrate 35 is performed by inserting the connection portions 21 and 31 of the contacts 20 and 30 into the through holes of the substrate and soldering them, but like the conventional example. Alternatively, the contacts 20 and 30 may be provided with compliant portions, respectively. In this case, reference numerals 22 and 32 in FIGS. 1 and 2 serve as driving shoulders.

Further, in the above embodiment, the normal contact 20 and the wide contact 30 are arranged in two rows, but the present invention is not limited to this, and they may be arranged in three rows or more. It goes without saying that it is good. FIG. 4 is a cross-sectional view of a plane orthogonal to the fitting direction in the insulator of the embodiment in which the normal contacts 20 and the wide contacts 30 are arranged in three rows. In FIG. 4, when the contacts 20 are arranged in three rows, the normal contact 20 is surrounded by the wide contact 30 on three sides at the end of the insulator 10 and on four sides inside, which further increases the shielding effect. It's getting higher.

In the present embodiment, the connector for board-to-board connection is taken as an example, but the use of the connector is not limited to this, and the present invention is applied to all connectors for which shielding of signal contacts is useful. It is possible.

[0020]

[Effect of device]

 As described above, according to the connector for board-to-board connection of the present invention, if the normal contact 20 is used as a signal contact and the wide contact 30 is used as a ground contact, at least three signal contacts are provided inside the insulator 10. Since it is surrounded by the ground contacts, it is possible to obtain a highly reliable connector for board-to-board connection that has a high shielding effect between signal contacts and has little crosstalk.
