Each connector assembly can be considered at least three, normally the combiner of four conduction subassemblies.For flexible connecting member assembly 501, these conduction subassemblies can comprise (shown in Figure 28 and 31) first group or the first array earth terminal 510, second group or 511, the first groups of the second array earth terminals or 512, the second groups of the first array signal terminals or the second array signal terminal 513.Shown in Figure 28,31 and 32, first group and second winding ground terminal is set together in mode side by side, they is adjoined each other, so that they form the ground connection benchmark 520 (Figure 30,31 and 32) of single common double thickness.These two grounding assemblies can be thought common formation or limit the center reference or the center line of flexible connecting member assembly.Consider that also single grounded parts also can be used for this purposes.
First group and second group of signal terminal 512,513 are arranged on the opposite side of common ground 520.Preferably, wish that first group and second group of signal terminal 512,513 further be arranged to make first group of terminal 512 and corresponding second group of terminal 513 horizontal alignment, shown in Figure 31 and 32.Also wish first group and second group of signal terminal 512,513 spaced apart, so that the pair of terminal of first group of terminal 512 " P " is on a side of common ground 520 (Figure 32), and the pair of terminal of second group of terminal 513 " P2 " is on the opposite side of common ground 520.By this way, form criss-cross setting or criss-cross figure with the common ground 520 (Figure 31) that distributes down along the centre of figure alignment, as shown at " CF ".Also have, the position of signal terminal 512,513 is such, their top and bottom margin (along " D " line of Figure 31 and 32) are alignd with the vertical end 580 of common ground connection 520, so that it keeps the electroaffinity to ground connection 520, rather than maintenance electroaffinity to each other, if this electroaffinity may take place when reaching D line top in the end of signal terminal.Figure 31 illustrates the end that remains on the signal terminal 512,513 of same level with the end 580 of ground connection 520, and Figure 32 shows the end that is positioned at below the D line.
This cross figure is realized by the structure and layout of signal terminal contact part 530, signal terminal contact part 530 is stretched to the front of this terminal flexible portion 531, and aforesaid terminal support bar 532 preferably constitute by insulating material and be installed in the cover or other supporting members in.The terminal contact part 530 of this terminal assemblies roughly forms L shaped, has the shank 533 that two junctions 534 between it combine.As shown in the figure, two shanks 533 of each signal terminal contact part 512 extend and leave common ground 520 (parallel substantially and perpendicular) along common ground 520.Because two shanks 533 combine, they are described as " solid " contact part in this manual.Contact part 530 and flexible portion 531 partly are combined in afterbody 535 by the terminal bodies that the housing 540 by insulation supports.L shaped terminal partly provides intensity and redundancy to signal contact.
Figure 33 at length shows the sandwich of flexible connecting member assembly 501, or the stratification structure.First and second ground terminal set 510,511 have the contact part, it preferably has the form of flat contact blade 518, they adjoin each other to form common ground connection 520, but the zone at the flexible portion 531 (Figure 30) that is arranged in terminal support bar 532 back is left mutually, as shown in figure 30.(Figure 29 and 30) in the insulating body 540,541 partly placed or be enclosed in to first and second signal terminal set 512,513, and this insulating body 540,541 supports also the main part of this terminal of envelope at least in part.Tail portion of terminal 535 is stretched out from a side of these insulating bodies 540,541, and the contact part is stretched out and preferably stretched out from the side that is adjacent from opposite side.
In operation, the insulating body 540,541 of placing first group and second group signal terminal 512,513 be assembled on first group and second winding ground terminal or its above opposite side to form the laminar part assembly 501 that is fixedly coupled.Additional insulating barrier parts 544,545 (Figure 33) or the parts that separate, or form a part or its extension of insulating body 540,541, additional insulating barrier parts 544,545 can be arranged between first and second terminals 512,513 and the earth terminal 510,511 and in the sweep zone in flexible portion zone 531, to prevent the short circuit unintentionally between this regional signal and earth terminal, and, if desired, between it, provide dielectric substance.As described in previous embodiment, whole terminal component can be used as single unit and inserts plug connector or socket connector, or from wherein taking out, thereby avoided taking maintenance and/or the repairing that whole connector assembly carries out apart.
As Figure 27 and shown in Figure 38, be fixedly coupled part assembly 502 and also comprise corresponding relative terminal.These terminals comprise first group and second winding ground terminal 550,551 with flat blade shape contact part 552.First group and second winding ground terminal adjoins each other in contact subregion 552.These earth terminals are in conjunction with the center common ground 521 that is distributed in formation between first and second signal terminal set 560,561, and preferred below the center of connector assembly 502.First group and second group of terminal 560,561 also partly are insulated main body 567,568 sealings, and insulating body 567,568 is used for preventing short circuit unintentionally between signal terminal and the earth terminal.Should be understood that if desired the part of signal terminal and earth terminal also can be flexible and contact with relative ground connection or signal terminal, as described about other embodiment of the present invention.
With reference to Figure 38, as can be seen, the contact portion 570 of first and second terminals 560,561 also is L shaped substantially.These contacts partly are different from flexible connecting member assembly " solid " contact part 530, and difference is that it comprises the bifurcated that separated by interval placed in the middle 574, or two contact leg, or two contact lever 572,573.Contact leg 572,573 stretches out forward from main part 575, and contact leg 572,573 is arranged to make one of them to extend along the earth terminal blade-section, and earth terminal blade-section (parallel substantially and perpendicular) is left in another extension wherein.These contact parts 570 also are provided with in couples and join with every side side of common ground connection (Figure 34), and the preferred contact section aligned with second group of signal terminal of the contact of first group of signal terminal part, represent with P and P2 respectively in Figure 35.They also preferably are arranged to the cross figure, so that they can partly match with the L shaped contact of flexible connecting member assembly reliably.Two contact legs have different length, and a contact leg is longer than another contact leg, make during cooperating short contact leg can contact the scope intrinsic deflection of leg easily at another.
This is shown in Figure 37 and 38, wherein can see, the contact length that horizontally extending contact shank divides 572 (when terminal assemblies is kept upright) to have divides 573 greater than vertically extending contact shank.In this, the free end 902 of a contact leg 573 can be along the path free deflection of the arrow among Figure 37, and in this scope, or mobile in " cup " of another contact leg, and does not hinder the free end 903 of another contact leg 572.Difference on the length also influences the degree of each contact leg deflection and reduces the maximum insertion force of connector.This minimizing can realize with the contact of the relative solid contact 530 of their socket connector by half (every centering is than of length) who contacts leg in pairs, and short subsequently contact leg contacts this relative solid contact 530.
Figure 24 A is an enlarged detailed, shows the engage of two L shaped contact terminal assemblies.As shown in the figure, level contact shank divides 572 will be that two contact shanks divide first and the leg that contacts of surface 533 slip joint of solid L shaped contact lever 512 in 572,573.Initial maximum insertion force only comprises makes long contact leg 572 cooperate needed power with solid L shaped contact lever 512, rather than contact leg 572,573 cooperates needed power simultaneously.
