The needle body termination 508 for the row's pin 502 stated is plugged with flexible contact contact 504.
The embodiment of the present invention：
Refering to Fig. 1, Fig. 3, Fig. 7, the present invention includes shell 200, fixed plate 300, pedestal 400, A substrates component 500 and B bases
Piece component 600.During assembling, first by the needle body termination 508 of A substrates component 500 and B substrates component 600 and flexible contact contact
504 connect；A substrates component 500 and B substrates component 600 are interleaved alternately with the substrate slot 405 of pedestal 400 successively again,
During the insertion substrate slot 405 of pedestal 400 of ridge 503 excessively of A substrates component 500 and B substrates component 600, downside on pedestal 400
The otch 403 on wall one side struts, and makes the clamping of window 404 of buckle 505 and pedestal 400, and the otch 403 on pedestal 400 reduces, A
Substrate component 500 and B substrates component 600 are fixed on composition pedestal component in pedestal 400.
Refering to Fig. 1, Fig. 2, Fig. 7, pedestal component is put into shell 200, guide finger 102 is installed at the back side of shell 200
And anti-mis-insertion code element 101；In the slot 201 that the inserted sheet 301 of both sides in fixed plate 300 is corresponded to insertion shell 200 both sides, Gu
Hangnail structure 302 on fixed board 300 is caught in the gap 202 in shell 200, and this measure limits fixed plate 300 and taken off from shell 200
While going out, pedestal component is fixed in shell 200 by fixed plate 300.
Refering to Fig. 1, Fig. 2, Fig. 4, the present invention has put several pins body opening 402 and square hole 401 on the platform of pedestal 400, has worked as A
During 405 grafting of substrate slot of substrate component 500 and B substrates component 600 and pedestal 400, flexible contact contact 504 is plugged on needle body
In hole 402；The setting of square hole 401, the dielectric constant on the periphery of flexible contact contact 504 is changed, make flexible contact contact 504 weeks
While be configured to medium by plastic material and air mixture, control the characteristic impedance of Difference signal pair with this and reduce signal
Loss.
Refering to Fig. 3, A substrates component 500 is made up of substrate 501, row's pin 502 and flexible contact contact 504, uses metal first
Stamping extrudes row's pin 502, row's pin 502 is fixed in substrate 501 by way of injection, and needle body termination 508 exposes side by side
On the outside of substrate, finally it is connected in exposed needle body termination 508 by way of crimping or welding with flexible contact contact 504
Together.
Refering to Fig. 5, more row's pins 502 of stationary arrangement are divided into three regions, region by the present invention according to arranging density
One 506 arranging density is maximum, and secondly, the arranging density of region 3 509 is minimum, and each region for arranging pin 502 exists in region 2 507
The plastic cement thickness of corresponding region is different on A substrates component 500 and B substrates component 600, so that row's pin 502 is in different regions
There is different dielectric constants, when signal transmits, there is relatively stable impedance, can also reduce the loss of signal transmission, improve signal
The quality of transmission.
Refering to Fig. 6, in A substrates component 500, wire D and E are a pair of difference, and wire A and B is a pair of difference, wire C
It is ground wire with F.Because wire D physical length is greater than wire E, so can be provided with wire D transmission path certain
The groove of length and width, change the dielectric constant around wire D, make transmission rate of the signal on wire D than on wire E
Transmission rate is fast, can thus make two signals in a pair of difference while reach, eliminate its propagation delay time.
