The embodiment that is used for the connector of high-speed signal transmission cable according to the present invention is illustrated in down with reference to the accompanying drawings.
Fig. 1 is the plan view of the first embodiment broken section, has wherein shed hiding to conduct electricity the insulation cover plate part 13 of afterbody 18,19,20 to the end portion of cable section 14.
A plurality of conduction splicing ears, as 15,16,17, be arranged in the insulation cover plate part of making by synthetic resin (as polytetrafluoroethylene) 11, afterbody 18,19,20 is arranged with the interval that equates basically each other on the base plate 12 that is fixed in insulating lid part 11, and is connected with splicing ear 15,16,17 respectively.
In addition, afterbody has the first pad part 22,24 and the second pad part 21,23,25, these pad parts are connected with the lead-in wire 1～10 of cable section 14 respectively, and these pad parts also are to be made by electric conducting material, and arrange with the interval that equates basically each other on base plate 12.
Each root of the above-mentioned signal lead of cable section 14 is similar to prior art and places between the earth connection, as, signal lead 8 is arranged between the ground lead 7,9.
In the present embodiment, the lead-in wire 1 on the left side is as ground connection three lead wire set 2,3,4 are arranged on the lower surface of base plate 12 and link to each other near lead-in wire 1 right side and with corresponding pad on the base plate, in addition, next three lead wire set 4,5,5 the upper surfaces of base plate extend and with base plate on corresponding pad part 22,23 link to each other, the lead-in wire 4 on the left side is a signal lead in three lead wire set, and all the other two lead-in wires 5, the 5th, ground lead, ground lead 5,5 are arranged on the pad part 23(second pad part) upward and with pad part 23 link to each other, it links to each other with ground connection afterbody 18 by coupling part 21, other ground lead 9,9 also by the pad part 25(second pad part) link to each other with ground connection afterbody 18 with coupling part 26.
Fig. 2 is the end view near the end portion of base plate Upper gasket part and cable section.
Fig. 3 is the expression second embodiment of the present invention, and it adopts public ground strip 35.
The first pad part 41,43 of insulating lid part 31, splicing ear (not shown), conduction afterbody 36,37,38, conduction, the second pad part 40,42,44, base plate 32 and the cable section 34 of conduction have the structure identical with first embodiment, and insulation cover plate 33 is removed.
Above-mentioned ground strip 35 places near the position, forward position of cable section 34 and has identical connection, the ground lead 52,55,57,59 of cable section 34 is bent that to be combined into lead right, and link to each other with ground strip 35, the signal lead 53,58 of cable section is placed on the first pad part 41,43 times and is coupled, and first pad part links to each other with holding wire afterbody 37,38 respectively.
In addition, paired ground lead 55 and 59 is bent and makes every over the ground towards the lower surface of base plate, and they are not shown with the second public ground strip 35() link to each other.
Be arranged on the second pad part 40,42,44 times from the extension 70 that public ground strip 35 stretches out, and it is coupled, they link to each other with ground connection afterbody 36 by coupling part 39, be positioned on the position of backplate surface, what be provided with is the signal lead 53,58 of cable section 34 and the position of these holding wires accordingly, correspondingly thereto be the ground connection extension of stretching out from ground strip 35, wherein the extension is connected with the second gasket part branch.Referring to Fig. 4, be arranged on the lead-in wire 51(56 that stretches out from cable section 34 and 60 not shown from the extension 70 that ground strip 35 stretches out) down and coupled.
As shown in Figure 8, be used for the habitual structure of high-speed signal transmission cable connector, interval signalization lead-in wire to equate basically on the surface of base plate 100, and ground lead is set on its another side, pad part 83,84,85 is set on the upper surface of base plate 40, each has width " P ", signal lead 91,93,95 is connected thereon, and be " P " at interval between signal lead promptly.
In contrast, in connector according to the present invention, as shown in Figure 5 and Figure 6 corresponding to embodiments of the invention, alternately signalization lead-in wire and ground lead on a surface of base plate, signalization lead-in wire on the another side of base plate, it is relative with ground lead on the another side, and ground lead be provided with relative with signal lead on the another side, therefore, suppose that base plate thickness is " t ", then the distance between adjacent signals line line is
（P
2+t
2）
1/2
Prior art with the ratio of crosstalk noise N of the present invention is
（P/p
2+t
2）
1/2
Lift one and implement, if the base plate thickness of being made by glass epoxy resin " t " is 0.8mm, coaxial flat cable be spaced apart 1.27mm, 1n pulse rise time second (1nsec), pulse duration 1v, and cable length is 1m, can obtain following experimental result:
Prior art the present invention reduces ratio
Crosstalk noise 13.4 9.2 69%
N（mv）
This ratio is 84% although can derive in theory, actual ratio is 69%, and this difference is sizable, and may exceed the measure error restricted portion, the reason of this big difference is as illustrated in Figures 5 and 6, signal lead be arranged to by ground lead around.
It is very simple and reduce the connector that is used for high-speed signal transmission cable of crosstalk noise to the invention provides structure.
In the present invention because between adjacent signals pad part on each surface of base plate, promptly respectively with adjacent legs that signal pads partly links to each other between distance enlarged, any crosstalk noise between it is reduced.In addition, each lead-in wire that is connected to signal pads part along its length direction by the lead-in wire institute that is connected to the ground pad part around.
