  The connector 1 having such a configuration is housed while the plug 2 shown in FIG. 1A is inserted into the socket 3 shown in FIG. 1B from the vertical direction and the ground plate 7 is sandwiched between the contacts 14d. The plug-side signal terminal 8 penetrates into the groove 12c and advances through the space 10c, and is connected to the contact 13d of the socket-side signal terminal 13, and electrical connection between them is achieved.

  As apparent from FIGS. 1 (a) and 1 (b), since the ground plate 7 is interposed in the longitudinal direction of the socket 3 in the plug and socket fitting state, the respective signal terminals 8 facing each other, In addition, the ground plate 7 directly exhibits a shielding effect between the signal terminals 13. In addition, between the adjacent signal terminals 8, in this embodiment, the ground terminals 19 are prepared for every 10 signal terminals 8: 10 so that they are in contact with the ground plate 7. The number of signal terminals 8: Every ten, that is, every small block, can produce a shielding effect. Similarly, between the adjacent signal terminals 13, the ground terminals 14 are prepared for every 10 signal terminals 13: 10 so that they are sandwiched and contacted with the ground plate 7. The number of signal terminals 13: Every 10 terminals, that is, every small block, can produce a shielding effect, and a large shielding effect can be obtained as a whole.

  Further, in this embodiment, as described above, the socket 3 is composed of the outer housing 10 and the inner housing 12, and the U-shaped bent portions 13c and 14c are held in a floating state therebetween. The misalignment can be absorbed and the coupling between the two can be ensured.

  Similarly, the signal terminal 8 of the plug 2 and the corresponding signal terminal 13 of the socket in this embodiment have 60 terminals on one side (60 pairs), and the ground plate 7 is too long. As shown in FIG. 4 which is a longitudinal longitudinal sectional view along the ground plate 7 of the plug 2 in FIG. 1A, the plug 2 is separated into three portions 7c, 7d and 7e. Each of the ground plates 7 (three portions 7c, 7d, 7e) is inserted into the plug housing 6 from the lower side to the upper side in FIG. The portion 7h comes into contact with the stopper 6a of the housing 6 and is positioned in the upward direction.

  Further, at the lower end of the ground plate 7, notches 7f are prepared for each of the 10 pairs of signal terminals 8 and at both ends thereof, and a ground terminal 19 is press-fitted there as shown in FIG. Supporting. Thus, the ground plate 7 is positioned in the downward direction. As described above, the solder tail 19b of the ground terminal 19 is soldered to a circuit board (not shown). As is apparent from FIG. 4, a notch 7g is also provided at the upper end of the ground plate 7 at a symmetrical position of the notch 7f, and this notch 7g is in contact with the ground terminal 14 of the socket shown in FIG. This corresponds to the child 14d.

  Next, the ground terminal 19 will be described in more detail with reference to FIG. 5 which is a cross-sectional view taken along the line CC of FIG.

  The ground terminal 19 includes a mounting tongue piece 19c and a ground plate clamping portion 19d. The mounting tongue piece 19c is press-fitted into a mounting groove 6d prepared in the plug housing 6, and the ground plate clamping portion 19d is a space provided in the housing 6. 6c. At that time, the clearance Y between the back end 7j of the notch 7f of the ground plate 7 previously fitted in the housing 6 and the bottom portion 19e of the ground plate clamping portion 19d is reduced, and the ground plate is inserted until they substantially contact each other.

If the bottom 19e of the ground plate clamping portion 19d of the ground terminal 19 and the back end 7j of the notch 7f of the ground plate 7,
The shape tolerance to the back end 7j of the notch 7f of the ground plate 7,
Tolerance from the bottom surface position of the ground terminal 19 to the mounting position of the ground plate 7
Crossing from the lower surface position of the ground terminal 19 to the bottom 19e of the ground plate clamping portion 19d,
When combined with leaving the large clearance Y, which is referred to as a total maximum tolerance value here, which is referred to as an overall maximum tolerance value, there arises a problem that the shielding effect is reduced due to the backward movement of the ground plate 7.

  That is, since the ground plate 7 is held exclusively by the elastic clamping force of the ground plate clamping portion 19d and the friction between the ground plate 7 and the plug housing 6, the plug 2 is inserted into the socket 3. That is, when the plug-side ground plate 7 enters between the contacts 14 d of the socket-side ground terminal 14, a force is generated in a direction to prevent the ground plate 7 from entering, and this force is transmitted from the plug housing 6 to the ground plate 7. The ground plate 7 moves backward until the clearance 19 is lost and the bottom 19e contacts the back end 7j of the notch 7f. In the state where the plug 2 is inserted into the socket 3, the clearance Y corresponding to the lost clearance Y and the penetration of the ground plate 7 into the socket 3 become shallow. Therefore, when the clearance Y is equal to or greater than the total maximum tolerance value, the shielding effect may be impaired.

  In this embodiment, the clearance Y is set as the overall maximum tolerance value, that is, in the state where the bottom portion 19e of the ground plate clamping portion 19d and the back end 7j of the notch 7f of the ground plate 7 are substantially in contact with each other. It is built in. For this reason, unnecessary retraction of the ground plate 7 does not occur, and the ground plate 7 can surely enter the socket 3 to a predetermined position (depth) and exhibit the intended shielding effect.

  That is, substantially contacting means that the clearance Y is set to the total maximum tolerance value or a value in the vicinity thereof.

  The present invention can be used as a connector with a ground plate particularly suitable for handling high-frequency signals.
