  Further, the plurality of terminal contact portions 64 of the signal terminal 62 and the plurality of ground contact portions 74 of the shield member are arranged in a substantially straight line at substantially equal pitch along the arrangement direction, and the plurality of terminal contact portions 68 of the signal terminal 66 and the shield. It should be noted that the plurality of ground contact portions 78 of the member are arranged in a substantially straight line at a substantially equal pitch along the arrangement direction. Similarly, the plurality of terminal fixing portions 63 of the signal terminal 62 and the plurality of ground fixing portions 73 of the shield member are substantially straight and substantially equidistant along the arrangement direction with the plurality of terminal fixing portions 67 of the signal terminal 66. The plurality of ground fixing portions 77 of the shield member are arranged in a substantially straight line at a substantially equal pitch along the arrangement direction. Such an arrangement also facilitates fixing to the substrate.

  In order to effectively prevent crosstalk, two terminal contact portions 64 are disposed between the ground contact portions 74, and two terminal contact portions 68 are disposed between the ground contact portions 78, respectively. Yes. Similarly, two terminal fixing parts 63 are arranged between the ground fixing parts 73, and two terminal fixing parts 67 are arranged between the ground fixing parts 77, respectively. As a result, the terminal arrangement is, for example, GSSGSGSGSSG. . . (Here, “S” indicates a signal terminal and “G” indicates a ground terminal). As described above, the ratio of the signal terminal to the ground terminal is set to 2: 1 and the multipoint shield contact structure is adopted, so that the number of shield contact points and connection points to the substrate can be increased, and the inductance can be reduced. .

  Note that the ground fixing part 73 and the ground contact part 74 included in the upper stage and the ground fixing part 73 and the ground contact part 78 included in the lower stage are shifted in the arrangement direction (the arrow “A” direction in the drawing). I want you to do it. For example, the ground fixing part 73 and the ground contact part 74 included in the upper stage are arranged on the foremost side in the arrangement direction (shown by the arrow “A” in the figure) in FIG. 77 and the seventh ground contact portion 78 are arranged third from the front. For example, if the upper terminal arrangement is GSSGSGSGSSG. . . , The lower terminal arrangement is SSGSSGSSGSGS. . . It is. With such an arrangement, the grounds are separated from each other, and crosstalk is more effectively reduced.

4). Reduction of Radiated Noise One effect obtained by this configuration will be described with reference to FIG.
8A is a partially enlarged view of the vicinity of the lower end of the receptacle connector 60 side in FIG. 2, and FIG. 8B is a partially enlarged view of the vicinity of the upper end of the plug connector 20 side in FIG. Show.
As is well known, when a signal current flows, a corresponding feedback current (return current) flows. For example, through the terminal fixing portions 63a and 63b and the signal terminal 62 as shown in (a), and further through the contact (65) between the signal terminal 62 and the signal terminal 22, as shown in (b), the signal terminal 22 and the terminal are connected. When the signal indicated by the arrow “f” flows through the fixing portions 23a and 23b, the ground is further reversed through the ground fixing portions 33a and 33b and the shield plate 32 as shown in FIG. Through the contact (75) between the contact portion 34 and the ground contact portion 74, as shown in (a), a feedback current as shown by the arrow “K” shown in the figure flows through the shield plate 72 and the ground fixing portions 73a and 73b. This feedback current forms a current loop with the signal current, and this current loop causes radiation noise. Therefore, the current loop is preferably as small as possible. Since the feedback current flows in a position close to the signal “f”, in order to reduce the current loop, it is necessary to provide a current path in a state as close as possible to the signal “f”.
In this regard, according to the configuration of the present invention, the shield plates 32 (36) and 72 (76) provided up to the vicinity of the substrate are widened along the arrangement direction (the arrow “A” direction in the figure) and Such a current loop can be made smaller because it is arranged adjacent to and substantially parallel to them. According to such a configuration of the present invention, for example, the feedback current corresponding to the signal current “f” returns on the shield plates 32 and 72 through substantially the same path as “f”, and the feedback current is output from the shield plate 72. Only when it is taken out, it is taken out to the outside through the ground fixing portions 73a and 73b away from the path of “F”. With such a configuration, radiation noise can be reduced.

5). Second Embodiment FIGS. 9 to 15 show a connector device 10A according to a second embodiment of the present invention. Here, FIG. 9 corresponds to FIG. 1 of the first embodiment, and FIGS. 10 to 15 correspond to FIGS. 2 to 7 of the first embodiment, respectively. In addition, the same reference number is attached | subjected to the member similar to 1st embodiment.

  The only difference from the first embodiment is the orientation of the receptacle connector. The plug connector used was the same as the plug connector 20 ″ in the first embodiment. The receptacle connector of the second embodiment is similar to the plug connector 20 ″ in the first embodiment with respect to the board. A so-called straight type installed vertically is used. The fitting hole 61 of the receptacle connector 60 ″ is provided perpendicular to the substrate 11. As a result, stacking fitting is performed between the plug connector 20 ″ and the receptacle connector 60 ″.

  Due to the difference in fitting direction, the terminal in the second embodiment, particularly the terminal shape on the receptacle side, is somewhat different from the terminal in the first embodiment. However, the basic configuration is exactly the same as in the first embodiment. Therefore, detailed description is omitted here.

6). Third Embodiment FIGS. 16 to 22 show a connector device 10B according to a third embodiment of the present invention. Here, FIG. 16 corresponds to FIG. 1 of the first embodiment, and FIGS. 17 to 22 correspond to FIGS. 2 to 7 of the first embodiment, respectively. In addition, the same reference number is attached | subjected to the member similar to 1st embodiment or 2nd embodiment.

  According to the configuration of the third embodiment, two receptacle connectors can be connected to one plug connector. The receptacle side is the same as the configuration in the first embodiment. What is necessary is just to consider the structure by the side of a plug having provided the structure by the side of a fitting in 2nd embodiment and 3rd embodiment on both right and left sides. In this configuration, no substrate is provided on the plug side. As shown in FIG. 16, the plug connector 20 ′ is provided with protrusions 21 and 31 on both the left and right sides. As a result, the receptacle connector 60 can be fixed to both sides of the plug connector 20 ′. .

  Due to the difference in fitting direction, the terminal in the second embodiment, particularly the terminal shape on the receptacle side, is somewhat different from the terminal in the first embodiment. However, the basic configuration is exactly the same as in the first embodiment.

7). Summary As is clear, the shield members provided in the plug connector 20 and the receptacle connector 60 exhibit a shielding function and also function as a ground terminal. As described above, by integrating the shield and the ground (ground terminal), in this configuration, the ground function is enhanced, the ground function is stabilized, and resonance is reduced. In general, when the ground terminal functions as a shield in this way, the ground terminal cannot be arranged between the signals. However, in this configuration, the ground fixing portion used as the ground terminal is grounded between the signal terminals. This problem is solved by extending the terminals.

  Further, in this configuration, both the shield plate 32 (36) provided on the plug connector 20 and the shield plate 72 (76) provided on the receptacle connector 60 are arranged along the fitting direction so that the signal terminals 22 (26) and The signal terminal 62 (66) is shielded from the outside. Therefore, at the time of fitting, the signal terminal is shielded from the outside by both the plug connector 20 and the receptacle connector 60, and more than the conventional configuration in which only one of the plug connector 20 and the receptacle connector 60 is shielded. Effectively, crosstalk can be reduced.
