JP-A-5-275139

  In the connector device 10 shown in FIGS. 1 to 7, the state of the shield with respect to the electrical connection portion pair 61 in a state where the plug connector 20 and the jack connector 30 are connected will be considered.

  The inverted L-shaped ground contacts 25 have the same orientation for each row, and the shield pieces 51 are arranged only vertically. Therefore, as shown in FIG. 7, at the end of each row on the Z2 side, the shield is in an open state, and the first signal transmitted through the electrical connection pair 60-1 and the electrical connection pair 60-2 are connected. There is a possibility that crosstalk occurs between the second signal to be transmitted as shown by an arrow C and crosstalk noise occurs in the first and second signals.

  If the pitch P between the rows of the plug contact pairs 23 is increased, crosstalk is less likely to occur, but the size of the connector device 10 is increased, which is not preferable.

  In addition, since the jack contact module 40 is not shielded between the adjacent jack contact pairs 44, the signal is transmitted between the adjacent signals even in the section where the signal is transmitted through the conductor portions 42A1 and 42B1 of the jack contact module 40. There is a possibility that crosstalk occurs and crosstalk noise occurs.

  In the jack contact module 40A shown in FIG. 8 and FIG. 9, the shield effect is not sufficient due to the shape of the shield members 70 and 71, though each conductor portion pair 45 is shielded. .

  In FIG. 7, the ground contact 25 and the shield piece 51 have a rectangular shape, and the distances a, b, c from the plug contact 22A and the jack contact 42A2 to the inner surface of the ground contact 25 and the shield piece 51 are as follows. It is not equidistant and the distance difference is large. For this reason, it has been difficult to improve impedance matching.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a connector device that can suppress crosstalk noise and achieve impedance matching with high accuracy.

Therefore, in order to solve the above-described problem, the present invention provides a first connector having a plurality of first contacts arranged in a grid along the column direction and the row direction;
A second connector having a plurality of second contacts aligned in a grid and a plurality of conductor portions extending from the second contacts;
In the connector device in which when the first connector and the second connector are connected, the first contact and the second contact are electrically connected.
The first connector has a pair of semi-circular or similar ground contacts arranged so as to surround each first contact from both sides thereof,
The second connector is characterized in that it has a pair of semicircular or similar shield members arranged so as to surround each conductor portion from both sides thereof.

  As described above, according to the present invention, crosstalk noise can be suppressed and impedance matching can be realized with high accuracy.

  Next, an embodiment of the present invention will be described.

  FIG. 10 shows a connector device 10U according to the first embodiment of the present invention. In each figure, the same reference numerals are given to the components corresponding to those shown in FIGS.

The connector device 10U includes a plug connector 20U and a jack connector 30U.

  Similarly, as shown in FIG. 11, the jack connector 30U has slits 33 and 33U formed corresponding to the ground contacts 25 and 25U.

  Plug connector 20U and jack connector 30U are connected in the same manner as described above. FIG. 12 shows a state of the shield with respect to the electrical connection portion pair 61 in a state where the plug connector 20U and the jack connector 30U of the connector device 10U shown in FIG. 10 are connected. In the first and third rows 27-1, 27-3, the side on which the shield is open is the Z1 side. In the second and fourth rows 27-2 and 27-4, the side on which the shield is open is the Z2 side. Thus, the side where the shield is in an open state alternates for each row. That is, when the end on the Z1 and Z2 side of each row is viewed, the row in which the shield is open and the row in which the shield is shielded are alternately arranged.

  Therefore, the occurrence of crosstalk between signals at the end portions of adjacent columns is suppressed, and the occurrence of crosstalk noise is suppressed.

The submodule 100B has a structure in which a jack contact component 42VB is insert-molded on a synthetic resin main body 101B having a substantially square plate shape. The jack contact component 42VB includes a conductive wire portion 42VB1, a fork-shaped jack contact 42VB2 at one end, and a terminal portion 42VB3 at the other end. Of the main bodies 101A and 101B, portions along the conductor portions 42VA1 and 42VB1 are protrusions 101Aa and 101Ba having a semicircular cross section. Conductive wire portions 42VA1 and 42VB1 constitute a conductive wire portion pair 45V.

  As shown in FIG. 16, the shield members 102A and 102B have a semi-cylindrical shape that is curved so as to coincide with the protrusions 101Aa and 101Ba, and a tongue-like shape having spring properties at the end on the Y1 side. Shield pieces 102Aa and 102Ba. The shield member 102A is fitted to the ridge 101Aa so as to cover and be fixed. The shield member 102B is fitted to the protrusion 101Ba and covered and fixed.

  The jack contact module 40V has a jack contact pair 44U and shield pieces 102Aa and 102Ba along the side 40Va on the Y1 side, and has terminal portions 42VA3 and 42VB3 along the side 40Vb on the Z2 side. As shown in FIG. 20B, the jack contact pair 44V includes jack contacts 42VA2 and 42VB2 arranged in the X1-X2 direction. The shield pieces 102Aa and 102Ba are arranged in the X1-X2 direction and are located on both sides of the jack contact pair 44V.

  The jack contacts 42VA2 and 42VB2 face the openings 32A and 32B, respectively. The shield pieces 102Aa and 102Ba are opposed to the slits 33V1 and 33V2, respectively.

  When the plug connector 20V and the jack connector 30V are connected, as shown in FIG. 19 (C), the plug contacts 22A and 22B pass through the openings 32A and 32B and reach the inside of the housing 31V. The ground contacts 25V1 and 25V2 pass through the slits 33V1 and 33V2 to reach the inside of the housing 31V and come into contact with the shield pieces 102Aa and 102Ba.

  Next, the state of the shield for the signal transmission path inside the connector device 10V in a state where the plug connector 20V and the jack connector 30V are connected will be described.

(1) About the part where plug contacts 22A and 22B and jack contacts 42A2 and 42B2 are electrically connected:
As shown in FIG. 20C, the plug contacts 22A and 22B, the jack contacts 42A2 and 42B2, and the electrical connection portions 60A and 60B are surrounded by semi-cylindrical ground contacts 25V1 and 25V2 from the X1 and X2 sides. Yes. The ground contact 25U1 surrounds the plug contact 22A, the jack contact 42A2, and the electrical connection portion 60A over an angle α = 180 degrees with these as the center. The ground contact 25V2 surrounds the plug contact 22B, the jack contact 42B2, and the electrical connection portion 60B over the same angle α = 180 degrees with these as the centers. The other signal pairs are similarly surrounded by the semi-cylindrical ground contacts 25V1 and 25V2 from the X1 and X2 sides.

  Since each signal pair is surrounded by the ground contacts 25V1 and 25V2 in this way, the crosstalk between the signal pair at the end of one column and the signal pair at the end of the adjacent column is lower than in the past. Is suppressed, and the occurrence of crosstalk noise is suppressed.

  Further, since the ground contacts 25V1 and 25V2 are semi-cylindrical, the distances a1, b1, and c1 from the plug contact 22A and the jack contact 42A2 to the inner surface of the ground contact 25V1, and the ground from the plug contact 22B and the jack contact 42A2 The distances a1, b1, c1 to the inner surface of the contact 25V1 are substantially equal. Therefore, compared with the prior art, it becomes easy to set the impedance as the target impedance, and impedance matching can be achieved.

(2) About the conductor part 42VA1, 42VB1 (conductor part pair 45V):
As shown in FIG. 19, the paired conductor portions 42VA1 and 42VB1 are surrounded by semicylindrical shield members 102A and 102B from the X1 and X2 sides. Similarly, the conductor portions of other signal pairs are also surrounded by shield members 102A and 102B having a semi-cylindrical shape from the X1 and X2 sides.

  Thus, for each signal pair, the occurrence of crosstalk between one signal pair on the shield members 102A and 102B and the adjacent signal pair is suppressed, and the occurrence of crosstalk noise is suppressed.

  Further, since the shield members 102A and 102B have a semi-cylindrical shape, the distances a3, b3, and c3 from the conductor portion 42VA1 to the inner surface of the shield member 102A, and the distance a4 from the conductor portion 42VA2 to the inner surface of the shield member 102B. b4 and c4 are substantially equal. Therefore, compared with the prior art, it becomes easy to set the impedance as a target impedance, and impedance matching can be achieved with high accuracy.

  Therefore, the connector device 10V has characteristics in which the occurrence of crosstalk noise is suppressed and the impedance is accurately matched as compared with the conventional connector device.

  FIG. 21 shows a connector device 10W according to a third embodiment of the present invention. The connector device 10W includes a plug connector 20V and a jack connector 30W. In the drawings, the same reference numerals are given to the components corresponding to those shown in FIGS. 10 and 14.

  The jack contact module 40W is different in the attachment structure of the shield members 102A and 102B.

  As shown in FIGS. 22, 23, and 24, the jack contact module 40W has a configuration in which a pair of submodules 200A and 200B are coupled, and shield modules 210A and 210B are attached to both sides thereof.

  The sub-module 200A has a structure in which a jack contact component 42VA is insert-molded in a substantially square plate-shaped synthetic resin main body 201A, and a protrusion 201Aa for positioning on the X1 side surface extends along the conductor portion 42VA1. Formed. The submodule 200B has a structure in which a jack contact component 42VB is insert-molded in a substantially square plate-shaped synthetic resin main body 201B, and a protrusion 201Ba for positioning on the surface on the X2 side extends along the conductor portion 42VB1. Formed.

  The shield module 210A has a configuration in which a plurality of shield members 102A shown in FIG. 16 are insert-molded in a substantially square plate-shaped synthetic resin body 211A, and a positioning groove 211Aa is formed on the X2 side surface. Is formed along the shield member 102A. The shield module 210B has a configuration in which a plurality of shield members 102B shown in FIG. 16 are inserted and molded in a substantially square plate-shaped synthetic resin main body 211B, and a positioning groove 212Aa is formed on the surface on the X1 side. Is formed along the shield member 102B. The insert molding is performed on the shield member frame in a state where a plurality of shield members are connected to the frame, and in the shield modules 210A and 210B, the accuracy of the arrangement of the shield members 102A and 102B is high.

  As shown in FIGS. 24A and 24B, the shield module 210A is positioned by fitting the groove 202Aa to the protrusion 201Aa, and the shield module 210B has the groove 202Ba fitted to the protrusion 201Ba. Each shield member 102A, 102B surrounds a pair of conductive wire portions 42VA1, 42VB1 (conductive wire portion pair 45V) from the X1 and X2 sides.

  Therefore, the connector device 10W has characteristics in which the occurrence of crosstalk noise is suppressed and the impedance is accurately matched as compared with the conventional connector device.

Here, since the jack contact module 40W has a configuration including the shield modules 210A and 210B, the assembly is simpler than the jack contact module 40V of FIG. In addition, the accuracy of the position of each shield member 102A, 102B with respect to the conductor portions 42VA1, 42VB1 is increased,
Therefore, the connector device 10W has a characteristic in which the impedance is matched more accurately than the connector device 10V of FIG.

  The characteristic structures of the connector devices 10U, 10V, and 10W of the first, second, and third embodiments can be applied to a connector device that transmits a single signal.
