31（32）Further comprise thering is a head position to adjust structure 34（34’）Structure 35 is adjusted with a tail position（35’）.Citing
For, the head position adjustment structure 34 of first signal terminal 31 connects between first middle section 312 and first signal
Between contact portion 311, for changing the relative position of the first signal contact site 311 and first middle section 312 so that this
One signal contact site 311 is detached from the perpendicular P where first middle section 312.The tail position adjust structure 35 between
Between first middle section 312 and first wave tail 310, for change first wave tail 310 with this in first
Between part 312 relative position so that first wave tail 310 is detached from the perpendicular where first middle section 312.
Similarly, which is also to be adjusted by its head position adjustment structure 34 ' and tail position adjustment structure 35 '
Whole second signal contact site 321 and the position of second signal tail portion 320.
In the present embodiment, each signal terminal 31（32）Signal contact site 311（321）By its head position tune
Whole structure 34（34’）Adjust its position, and wave tail 310（320）Then structure 35 is adjusted by its tail position（35’）It adjusts
Its whole position.But in other embodiments, can be as needed, head position tune is set only on a part of signal terminal
Whole structure 34（34’）Or/and tail position adjustment structure 35（35’）, can also realize two signal contact sites of each differential pair
311（321）Longitudinally parallel arrangement, and two wave tails 310（320）Then transversely it is staggeredly arranged with vertical.
In the present embodiment, as shown in Figure 14, Figure 15, head position adjustment structure 34（34’）Or the tail position tune
Whole structure 35（35’）It can be one or more extended segments downward or upward or towards oblique side by being stamped and formed out, may be used also
To be one or more bending section formed by leftward or rightward bending, and it can be one by the extended segment and the bending section
The combined segment being combined into.In fact, these adjustment structures are primarily used to ensure the first adjacent signal terminal and second signal
While the middle section of terminal forms side coupling, signal contact site can be realized with butt connector to connection function, and
Its wave tail is then arranged with certain pattern, so as to be electrically connected with circuit board.
As shown in figure 13, in the first sheet type needle stand 21, which also has at least one adjacent to first side
The first convex block 213 and at least one the second convex block 214 set adjacent to the second edge 212 that edge 211 is set.In this implementation
There is a line to be arranged along the first convex block 213 and one that the first edge 211 is set along second edge for example, first frame 210
Second convex block 214 of 212 settings, wherein at least part quilt of the tail position adjustment structure 35 of every one first signal terminal 31
It is embedded in first convex block 213, and at least part of head position adjustment structure 34 is embedded in second convex block 214.
