Embodiment

Fig. 1 is that the exploded perspective of communications connector that comprises plug 102 and can insert the socket 104 of plug 102 is represented.As terminal, and socket 104 can be connected to the block (all not shown in Figure 1) of another section twisted pair communications cable or punching downwards to this plug 102 with one section twisted pair communications cable (not shown).

Shown in scheming from left to right, socket 104 comprises main shell 106 and bottom front sled 108 and the top front sled 110 that supports eight plug interface contacts 112 is set.Through hole by PCB 114 is connected with PCB (printed circuit board (PCB)) plug interface contacts 112 from the front.As shown, eight IDC (insulation displacement contacts) 116 are connected with PCB 114 by the additional vias of PCB 114 from behind.Back shell 118 with IDC 116 passages is as providing interface to twisted pair communications cable or downward punching block.Can be used for the improved discussion background that connector 100 improves crosstalk performance below common connector 100 conducts shown in Fig. 1.

The rough schematic view of Fig. 2 conceptually shows the part that mainly causes near-end cross and can be used for compensating near-end cross of connector assembly 300.Plug 302 and plug interface contacts 304 provide capacitive character and inductive cross-talk composition C respectively _Plug+ L _PlugAnd C _{The contact}+ L _{The contact}But global approximation is the vector of crosstalking A(referring to Fig. 4).Thereby the compensatory zone 306 on the PCB 308 provides crosstalk compensation to produce compensation vector BConsider owing to transmission delay takes place BWith respect to APhase-shifted, near-end cross zone 310 (illustrating with respect to the reverse side of IDC 312 at PCB 308) can contribute additional crosstalking CReduce in conjunction with the upward influence of phase-shifted of crosstalking.

Fig. 3 shows vector on time shaft A, BWith CNotice the vector of crosstalking AWith COn polarity with compensation vector BOn the contrary.Vector is to be caused by physical distance (causing transmission delay T1 and T2) between the position of compensatory zone 306 and crosstalk zone 310 and plug 302 contact plug interface contacts 304 and the relative dielectric constant that inserts conductive path along the relative displacement of time shaft.

Fig. 4 shows vector on polar axis shaft A, BWith C, wherein the displacement along Fig. 3 time shaft is converted into respect to the vector of crosstalking APhase-shifted.When frequency increases, BPhase-shifted can to AIncrease, and CPhase-shifted can with AIncrease on the contrary.For less relatively phase-shifted, can be minimized by design compensation zone and crosstalk zone in conjunction with crosstalking, with zero frequency place in expectation | B+ C| approximate | A|.

For the frequency of about 300MHz, for near-end cross, the multizone crosstalk compensation techniques shown in Fig. 2-4 is suitable for meeting Cat.6 (TIA-568B) requirement.Yet in higher frequency, this technology is also unsatisfactory.In order to illustrate, Fig. 5 shows vector on polar axis shaft A, BWith C, but with respect to compensation vector BIn order to minimize in conjunction with crosstalking, should with | B| be chosen to approach | A+ C|.Yet, when frequency increases, AWith CWill the bigger phase-shifted of experience, evidence is the bigger angle of vertical direction relatively on the polar axis shaft of Fig. 5.Because the cosine of these increasing angles can reduce, | A+ C| can become is significantly less than | B|, cause not satisfied connector performance.This effect has been shown in Fig. 6 A-6C, when its medium frequency increases | A+ C| ratio becomes | B| less relatively.

Fig. 7 show the technology that use discusses referring to Fig. 2-6 typical Cat.6 connector in conjunction with crosstalk performance.Notice that NEXT crosses the frequency that TIA-568B requires limit place.

But adapt to the line frequency that surpasses the above-mentioned technology of use for improving the NEXT performance, can in connector, comprise additional coupling with the amplitude that disproportionately increases with respect to typical case's coupling and frequency.In addition, can change an existing coupling to have amplitude with respect to other disproportionate variation that is coupled.Previous typical connector coupling is capacitive or inductive mutually, causes being proportional to the amplitude of frequency (per ten times of about 20dB).The relative amplitude of these typical connector couplings roughly keeps identical when different frequency.By introducing coupling, the compensation of the phase-shifted that caused by transmission delay (is seen top Fig. 2-6C) can postpone in conjunction with the increase of crosstalking at upper frequency with respect to other disproportionate increase that is coupled.

Fig. 8 A-15 with and additional disclosure show additional coupling other realize that this additional coupling has corresponding to the frequency amplitude that increases with disproportionate speed of typical case's coupling relatively.Under the situation that does not depart from spirit and scope of the invention, also can use other realization.Fig. 8 A-10C is the polar plot that the expectation coupling feature is shown.It after the description of Fig. 8 A-10C the discussion that reaches other method of expectation coupling feature.

Realize according to first, additional coupling be have with A, BWith CThe 4th coupling of the amplitude of different frequency dependences DFor example, at lower frequency, A, BWith CWith the rate variation of per ten times of 20dB, and DWith more low rate variation, per ten times of all 5dB according to appointment.Then, in upper frequency (for example greater than interested zero frequency), DChange (for example 30dB is per ten times) with higher rate, and A, BWith CConstant relatively in per ten times of maintenances of 20dB.By selecting in zero frequency | B|-| D| with | A|+| C| equate, approach zero in conjunction with crosstalking at lower frequency, shown in Fig. 8 A.Fig. 8 B shows when frequency increases, AWith CThe phase angle increase, cause less field amplitude component to be offset | B|.Yet, increase more fast | D| increase to compensate and reduce | A+ C|.Fig. 8 C shows this effect under much higher relative frequency.

In second realizes, shown in Fig. 9 A-9C, the compensatory zone vector BBe designed to have with AWith CThe amplitude of different frequency dependences.For example, at lower frequency, if AWith CWith the rate variation of per ten times of 20dB, then BCan select with more low rate variation, such as per ten times of 15dB.In upper frequency (for example greater than interested zero frequency), BCan change with the higher rate negative sense (for example-30dB per ten times), and AWith CConstant relatively in per ten times of maintenances of 20dB.Realize comparing with first shown in Fig. 8 A-8C, in second realizes, do not need additional coupling.By inciting somebody to action in zero frequency | B| be chosen as and approach | A|+| C|, approach zero in conjunction with crosstalking at lower frequency.When frequency increases, | A| and | C| disproportionately faster than | B| increase, so | B| can approach in the frequency that increases | A+ C| (referring to Fig. 9 B and 9C).

In the 3rd realizes, shown in Figure 10 A-10C, coupling AWith CBe selected at the frequency that is higher than zero frequency and have ratio BBigger amplitude is to the correlation of frequency.For example, at lower frequency, A, BWith CAll with the rate variation of per ten times of 20dB.Yet,, can select at upper frequency AWith CChange with higher rate, such as per ten times of 25dB, and B is maintained at about per ten times of 20dB.By inciting somebody to action in interested zero frequency | B| be chosen as and approach | A|+| C|, approach zero in conjunction with crosstalking at lower frequency.Because | A| and | C| higher frequency dependence increases more fast | A| and | C| can compensate by high frequencies of operation cause usually with reducing of occurring of the phase angle that increases | A+ C|.Therefore, the combination that can keep lower in wider frequency is crosstalked, shown in Figure 10 A-10C.Certainly, change ANeed the change of plug self probably, this is unacceptable in some cases.Yet, even change separately CSome benefits can be provided.

Three kinds of realizations of above-mentioned this only are examples in the cards.Be applied to another from one, may be different with the relative amplitude rate of change that per ten times of dB provide, depend on the concrete structure and the material of connector assembly.In addition, relative amplitude can be applicable to improve in zero frequency or near the performance of other frequency outside it with the notion of frequency change.Zero frequency is to select for above example, because it is regulated to improve the better starting point of high-frequency operation as being used to.For present communications applications, zero frequency is usually near 100-250MHz.Different connector designs show different zero frequencys probably.

In better embodiment, communications connector comprises and is used for carrying out the electric plug interface contacts that contacts with the plug plug contacts that wherein plug interface contacts and plug contacts are introduced to connector and crosstalked.In the transmission communication signal frequency, this is crosstalked and has relevant first frequency correlation according to just.Socket has at least two crosstalk compensation zones, wherein at least one crosstalk compensation zone comprises the coupling with relevant second frequency correlation, and this relevant second frequency correlation is different from the first frequency correlation relevant with plug interface contacts and plug contacts basically.The first frequency correlation is that the amplitude of per ten times of about 20dB changes.The second frequency correlation be from per ten times of about 0dB of first frequency to amplitude in per ten times of variations of the about 20dB of second frequency.In second better embodiment, the second frequency correlation be from per ten times of about 20dB of first frequency in the amplitude of second frequency less than per ten times of variations of 20dB.At last, in the 3rd better embodiment, the second frequency correlation is the changes in amplitude of per ten times of 20dB, and the first frequency correlation be from per ten times of about 20dB of first frequency in the amplitude of second frequency greater than per ten times of variations of 25dB.

Can use some selection technology that amplitude is regulated for the correlation of frequency.Below discuss five kinds that list in these technology; Yet, under the situation that does not deviate from the spirit and scope of the present invention, can use other technology.

No. 1 coupling is selected: Figure 11 A-11C shows the example of first execution mode, electric capacity wherein is set connects with the mutual induction coupling.Shown in Figure 11 A, self-induction equivalent electric circuit 11B and emergent equivalent electric circuit 11C, the mutual induction coupling produces and the electric current that flows through the current opposite in direction of capacitor.At lower frequency, lower by the coupling of capacitor; Therefore, the reverse current that produces in the inductance secondary side is also lower.Along with frequency raises, the coupling rising by capacitor has increased the electric current by the main side of inductance, therefore causes the higher reverse current by the inductance secondary side.As a result, coupling reduces with being proportional to frequency.In better embodiment, " the stablizing source (balanced source) " the 1262nd shown in Figure 11 A, pairing 3 and 6, and " stablizing place (balanced sink) " the 1264th, pairing 4 and 5.Figure 12 shows another configuration of this execution mode, wherein matches 3-4 and 5-6 to illustrate in the left side.

Figure 13 A-13C shows how to realize No. 1 coupling selection in back rotary connector contact design 1300 or preceding rotary connector contact design 1302.The example that shows the result's coupling in the situation that building-out capacitor is set on interface PCB 1304 is shown in the simple equivalent circuit 1306.

Before showing, Figure 14 A and 14B in the Rotation Design 1406 of in the Rotation Design 1400 and back capacitively coupled position can be set.In preceding Rotation Design 1400, electric capacity is placed in most advanced and sophisticated nose region 1404 in the mode that prevents to contact with plug 1402 physics.In the Rotation Design 1406 of back, once more electric capacity is placed in the most advanced and sophisticated nose region 1410, compare the opposite side of this electric capacity at plug 1408 with preceding Rotation Design.For back Rotation Design 1406, electric capacity can be placed in the top of most advanced and sophisticated nose region 1410 contacts or below, as long as it does not contact with plug 1408 physics that insert.The displacement shown in Figure 14 A and the 14B cause capacitive couplings C35 and C46 (respectively to 3 and 5 and to 4 and 6) and mutual induction coupling M43 and M56 (respectively to 4 and 3 and 5 and 6).

Figure 14 C shows the another location in another preceding Rotation Design 1412, as schematically showing among Figure 12, wherein coupling can be set.Before selection in the Rotation Design 1412, with coupling be provided with and plug 1414 and plug interface contacts 1416 between the point that electrically contacts by much closer.This nearer setting derives from coupling is placed in the opposite side of plug interface contacts 1416 with respect to plug 1414.This can realize by moving into PCB from the compensation of the inductive of the conductor shown in the most advanced and sophisticated nose 1404 of Figure 14 A, for example the flexible PCB shown in Figure 24 A.This causes the transmission delay that reduces, and the phase-shifted that therefore reduces, and it provides better crosstalk performance.

No. 2 couplings are selected: in second selected, with respect to other coupling, this coupling adopted the capacitive form with frequency change.An example of this electric capacity is the electrolytical capacitor that has with the frequency change dielectric constant.

No. 3 couplings are selected: according to the 3rd selection, coupling is mutual inductance, has relevant frequency and relies on inductance.An inductance element that example is made up of iron material of this inductance.Iron (compound that for example has iron oxide and nickel-zinc or manganese-zinc) generally has from about 100kHz to 1GHz and begins magnetic permeability as the function significant change of frequency.For example, the mixture of iron oxide and nickel-zinc has 10 to 1,500 initial permeability in 1MHz to 1GHz scope.

No. 4 couplings are selected: in the 4th selected, coupling was the electric capacity of connecting with one or more frequency-dependent resistors.For example, conductor or semiconductor resistor can be set and facilitate the use skin effect at upper frequency increase resistance.

No. 5 couplings are selected: according to the 5th selection, electric capacity and self-induction coupling are arranged in parallel.The inductance that increases at upper frequency can cause by the less coupling of electric capacity.

Figure 15 show typical Cat.6 through improved in conjunction with crosstalk performance, it is by using the above innovative technology of discussing referring to Fig. 8 A-14 to obtain.Notice that NEXT surpasses frequency that TIA-568B requires restriction far above among Fig. 7.

The high-frequency effects of describing referring to Fig. 2-7 and implement above-mentioned solution with the demand that obtains acceptable high-frequency operation mainly from the physical distance between the plug interface contacts and first compensation.By reducing this distance, can obtain more performance (i.e. phase-shifted still less) owing to transmission delay in high-frequency.For example, first compensation point is moved on to apart from plug/jack interface and provide better crosstalk performance less than about 0.200 inch meeting.Figure 16-28 shows and can carry out changing with the physics that shortens distance between the plug interface contacts and first compensation to socket.These changes can replace or carry out in conjunction with technology described above.

Figure 16 is the right side schematic diagram of running contact configuration 1600 before illustrating, and comprises the vertical joint PCB1606 that is arranged on a plurality of plug interface contacts 1602 in contact brackets and the front sled 1604 and has the contact part 1608 that links to each other with crosstalk compensation zone (not shown).Compare with the ordinary plug interface contact, this plug interface contacts 1602 is longer, so they contact with the contact part 1608 of vertical joint PCB1606.As a result, contact part 1608 and insert plug and plug interface contacts 1602 between contact point between distance 1610 much smaller than the ordinary plug interface contact, this can find out by comparing with Figure 17 middle distance 1700 apart from 1610.Because have shorter distance between the plug contacts and first compensation through improved design, transmission delay is shortened, and obtains littler phase-shifted.This allow the upper frequency ratio need not this design can getable better crosstalk compensation and operation.Should notice that Figure 17 has comprised the induction coupling of the auxiliary crosstalk compensation shown in 1702 summaries.

Figure 18 is to use top, the right side exploded perspective view of the connector body 1800 of above notion.This socket 1800 comprises bottom front sled 1804 and top front sled 1808, and each all is mechanically connected to a plurality of plug interface contacts 1806.First terminal 1810 of plug interface contacts 1806 can be inserted in the through hole of interface PCB 1812, and second terminal 1814 comprises the plug interface contacts terminal, and this plug interface contacts terminal contacts with compensatory zone on the interface PCB 1812 allowing than the longer of common socket.The parts assembling that will comprise bottom front sled 1804, plug interface contacts 1806, top front sled 1808 and interface PCB 1812 afterwards is inserted in the shell 1802.Also a plurality of IDC 1816 are inserted in the through hole on the interface PCB 1812.Back sled 1820 is fit into shell 1802.Hookup wire hold cap 1818 with receive four pairs of twisted pair communications cables be used to pass the back sled 1820 be connected with IDC 1816.Line can be held cap 1818 afterwards by being pressed on the sled 1820 of back, form integrated communication jack.

When above technology was used selectable conductor path between the plug interface contacts and first compensation, second technology comprises by flexible PCB being connected in plug interface contacts settled the more close plug contact point of first compensatory zone.As example, can on flexible PCB, so that being provided, capacitive cross-talk compensate by the etching buffer condenser, thus the electrical property of improvement socket.

Figure 19 shows six flexible PCBs 1900, and it has six teeth 1902 that can be used for flexible PCB 1900 is connected in the plug interface contacts 2000 that is supported in the front sled 2002, as shown in figure 20.Though it also is possible that 1900, eight realizations of six flexible PCBs are shown.Six designs can preferably be used for avoiding the damage of standard Registered Jack-45 when inserting six RJ-45 plugs.Six RJ-45 plugs of standard have than the outstanding farther plastics in six contacts, and this will cause the extra displacement of plug interface contacts in the socket.Six flexible PCB 1900 permissions must be more farther than plug interface contacts 2 to 7 with plug interface contacts 1 and 8 displacements.This flexible PCB 1900 preferably is made of the layer of copper that sticks on polyester or the polyamide substrate.(for example etching) removal copper is to generate the crosstalk compensation district in many ways.The tooth 1902 of flexible PCB 1900 can be connected in plug interface contacts 2000 in arbitrary mode.Supplementary technology can comprise for example ultrasonic bonding or thermal weld.

Figure 21 and 22 illustrate can flexible PCB 1900 is crooked up or down stereo representation.Other direction and configuration also are possible.Figure 22 also shows the appropriate area that is used for tooth 1902 is connected in the plug interface contacts 2000 of plug interface contacts 2000.Be relevant to the number of tooth 1902, flexible PCB 1900 can be connected in suitable contact coordinatedly.

Figure 23 and 24 be illustrated in that plug interface contacts responds that plug inserts and when mobile flexible PCB 1900 in socket, experience the simplification right cross of upwards (Figure 23) or downward (Figure 24) deflection.In the time of in plug insertion socket, flexible PCB 1900 follow each contact random skew and no matter whether it is connected in flexible PCB 1900.The tooth of flexible PCB 1900 also allows because the physical alterations of the contact skew that the change of plug contacts terminal height causes.Need in shell upwards being offset flexible PCB 1900 or in the sled of preceding top, setting up the space of Figure 23 for the downwards flexible PCB 1900 of Figure 24.The positioned vertical design of noticing the plug interface contacts 2350 shown in Figure 23 and 24 has advantageously provided the additional inductance crosstalk compensation.Though this design is preferable, also optionally use other design.

Figure 24 A is the simplification right cross that the selectivity arrangement of flexible PCB 1900 on the plug interface contacts 2350 is shown.In the selectivity that can use for example design shown in Figure 14 C was settled, flexible PCB 1900 and plug (not shown) were positioned at the opposite side of plug interface contacts 2350.This makes that coupling and plug contact point 2370 on the flexible PCB 1900 are very approaching, causes transmission delay that reduces and the phase-shifted that therefore reduces.Therefore this provides better crosstalk performance.In order when inserting plug, to allow the skew of plug interface contacts 2350, can design flexible PCB 1900 and avoid contacting, for example plug interface contacts 2350 than lower part with the socket other parts.

Figure 25 A is the right side top perspective view, and Figure 25 B is a lateral plan, and Figure 25 C be can be used according to the invention with the front view of an execution mode of flexible PCB 2400 that crosstalk compensation is provided.This PCB2400 comprises main part 2402 and additional teeth, and for example tooth 2404.Main part 2402 supports a plurality of capacitive plates (in this case, four plates are corresponding to plug interface contacts 3-6) so that capacitive couplings to be provided.Shown in Figure 25 D-I, also provide the inductive couplings composition as meeting to the path of capacitive plates.Tooth 2404 is used as annex mechanism, is used for one of scheme shown in application examples such as Figure 23-24A PCB 2400 is connected in plug interface contacts.Though can use any suitable attachment technique, in the execution mode that illustrates, use resistance welded rivet 2406.Rivet 2406 is as the contact point in capacitive plates and its path except PCB 2400 being connected in plug interface contacts (or another conductor that is connected with plug interface contacts).This is shown in Figure 25 B-I that four layer capacitance plates 2412 and path (2408a-d) are shown, and wherein rivet 2406 passes path and outstanding to form suitably contact in tooth 2404.

Figure 25 D is the front view that the PCB 2400 of tooth is arranged, and is illustrative ease, and tooth is straight structure.Figure 25 E be from PCB 2400 bottoms when Figure 25 D center line A/A watches the cross-sectional view in capacitive plates and path.Note only supporting on the not shown PCB 2400 of Figure 25 E capacitive plates and path or as the part of dielectric or insulator.Figure 25 D-I shows and how settles capacitive plates and path to cause the density of inductance coupling high high relatively in relative short distance with being relative to each other.For example, the capacitive plates 2412a of conductor 5 and path 2408a are top plate and the paths that illustrates in Figure 25 D, have side " U " shape.Shown in the dotted line and solid line of Figure 25 D, use identical " U " shape but different orientation with 6 for conductor 3,4.The physics of capacitive plates is settled and overlapping region has determined capacitively coupled amount.Similarly, the mutual distance in path and overlapping region have determined the amount of inductance coupling high.Figure 25 E also shows electric current relevant flow direction in path separately, and this provides the high density inductive couplings.Figure 25 F-25I shows relevant with the 5th, the 3rd, the 6th and the 4th conductor of eight conductor sockets respectively path 2408a-d and capacitive plates 2412a-d respectively.

Figure 26 is to use top, the right side exploded perspective view of the connector body 2500 of flexible PCB notion.This socket 2500 comprises bottom front sled 2504 and top front sled 2508, and each all is mechanically connected to a plurality of plug interface contacts 2506.In the through hole that first terminal 2510 of plug interface contacts 2506 can be inserted among the interface PCB2512, simultaneously second terminal 2514 is connected in flexible PCB 2516 so that crosstalk compensation to be provided.The parts assembling that will comprise bottom front sled 2504, plug interface contacts 2506, top front sled 2508, interface PCB 2512 and flexible PCB 2516 afterwards is inserted in the shell 2502.Also a plurality of IDC2518 are inserted in the through hole on the interface PCB 2512.Back sled 2520 is pushed in shell 2502.Be provided with line hold cap 2522 with receive four pairs of twisted pair communications cable (not shown) be used to pass the back sled 2520 be connected with IDC 2518.This line can be held cap 2522 then by being pressed on the sled 2520 of back, form integrated communication jack.

Describing according to flexible PCB Figure 19-26 o'clock, this only is an execution mode, and under the situation that does not deviate from the intent of the present invention scope, it also is possible using other execution mode of rigidity PCB or other compensation scheme.Flexible PCB helps to reach the mechanical constraint that exists in some connector designs.

Referring now to Figure 27-29, another technology of distance between the interface that is used to shorten between crosstalk compensation zone and plug and the plug interface contacts is described.In the 3rd technology, back rotary connector interface contact design and potential compensation PCB together use the crosstalk compensation that extremely approaches interface between plug and the plug interface contacts to provide.As a result, transmission delay is minimized, and the phase-shifted of same crosstalk compensation is also minimized.This has simplified total compensation scheme by the number that reduces to crosstalk with compensatory zone, allows better to operate at upper frequency.

Figure 27 is the right side top perspective view of plate connector 2600.This socket 2600 comprises that design receives the shell 2602 of plug (not shown), back sled 2604 and is provided with the line of received communication cable (not shown) to hold cap 2606.Shell 2602, back sled 2604 and line hold cap 2606 and are combined together to form plate connector 2600.

Figure 28 is top, the right side three-dimensional exploded view of socket 2600.Except shell 2602, back sled 2604 and the line of describing referring to Figure 27 holds cap 2606, socket 2600 comprises that also design supports the PCB support 2708 of compensation PCB2710 and interface PCB 2712.A plurality of plug interface contacts 2714 have to be inserted first terminal 2716 in the through hole on the interface PCB 2712 and is received when entering socket 2,600 second terminal 2718 that some of them are at least slided along compensation PCB 2710 at plug.In the through hole on a plurality of IDC 2720 insertion interface PCB 2712.Figure 29 shows the close-up, perspective view of inserting the plug interface contacts parts assemblings (except the IDC 2720) of shell 2602 before being placed in back sled 2604 on the shell 2602.Socket 2600 assemblies also comprise telecommunication cable location and install online holding in the cap 2606, then with it by being pressed on the sled 2604 of back.

Plug interface contacts parts assemblings (not having IDC 2720) shown in Figure 29 are designed to hold 8 pin plugs or 6 pin plugs.When being inserted into 8 pin plugs in the socket, downward power makes contact 2 to 7 slide along compensation PCB 2710. Contact 1 and 8 skews, but do not slide along compensation PCB 2710.On the contrary, when being inserted into 6 pin plugs in the socket, also slide along compensation PCB 2710 in contact 2 to 7.Yet because the additional plastic material on 6 pin plugs, contact 1 and 8 is offset more than contact 2 to 7.The space of compensation PCB 2710 tops that plug interface contacts 1 and 8 provides allows this additional offset, keeps enough normal forces between plug and the plug interface contacts 2714 simultaneously.

The inductance of compensating circuit strengthens

More than the compensating circuit described referring to Figure 11 A-14C forms by known electric device, can be by using the realization of standard design and treatment technology.In addition, when the path of circuit not being set restriction, produce and have basically that inductive nature is simple relatively with the mutual induction circuit as these compensation arrangements.Yet the confined space that being connected in the pcb board of plug interface contacts in jack housing provides needs novel process technology and device, so that set up best inductive nature with short as far as possible path.These technology should allow phase delay is incorporated in the compensating circuit effectively, although limited PCB zone needs the path of shortening.

A kind of technology is to use ferromagnetic material to increase by two kinds of mutual induction inductance between the signal path.Magnetic material moves very strong reaction to the electric charge in first signal path, and this also produces magnetic flux.This magnetic flux presents on the orientation of magnetic material magnetic pole, and then this can influence the dislocation charge directly relevant with second circuit.Key is a magnetic material as can be with two signal path magnetic-be electrically coupled to by the geometry of used iron or magnetic material and the medium of the determined degree of magnetic property.Figure 30 shows the annex 3000 as the iron material structure of external inductance element, is used to make two signal path 3002 to pass therein.Cored structure can be some arc, and the path is passed under this structure.In addition, this structure can have the solid semi-cylindrical shape, perhaps can be some rectangular archwire forms.Outside magnetic core can be made up of the synthetic of iron, iron, nickel, steel or these metals of powdered.In addition, it can be made up of other ferromagnetic material with magnetic-electric inductive nature.This magnetic core can be made separately by plate, and can weld, bonding or go up in the correct position of the pre-position that makes by being pressed in PCB.Connecting these parts can be different from the makers' place of PCB and carry out after PCB finishes dealing with.

Figure 31 shows the other method that can be used for increasing mutual induction inductance between the signal path.In the method that illustrates, do not need external component to produce inductance coupling high between the path.But the geometry in change path self is with the coupling between the maximization two paths of signals.In this example, a paths 3100 forms first coil 3102, and second path 3104 forms second coil 3106 simultaneously.Two coils overlap with specific amount and geometry, allow the interaction of the enhancing of unit path between two paths.In addition, can use different path geometry structures, so that increase the inductance coupling high between the signal, for example ellipse or rectangular coil.

Figure 32 shows two kinds of similarity methods that can be used for increasing mutual induction inductance between the signal path.Similar with above-mentioned first method, the method use core material shown in Figure 32 increases the inductance coupling high between two signal path.In one approach, by directly on two parallel paths 3202 and 3204, settling magnetic coupler 3200 to obtain coupling.Can use various technology magnetic material to be used for the surface of plate 3206.For example, this material can be melted and be used drop to disseminate the device deposition from the teeth outwards, it can be coupled with mask (screenon), it can be immersed by use with etching technics adds, it can be rolled, and perhaps this magnetic material can be added by use permission similar technology graphical and the localization deposition materials on circuit board surface.

In the other method shown in Figure 32, the magnetic couplings material can be inserted among the PCB 3206 by the hole 3208 of making on the plate.Can with magnetic material 3210 hole 3208 be filled by using then such as mask process.In addition, can push magnetic material 3210 is fit to enter among the PCB.Hole 3208 can by the cylinder magnetic plug that is used for filling a vacancy around.In addition, the hole can be made up of the different geometries of inductance coupling high between the path that allows to pass core material.

In two execution modes shown in Figure 32, magnetic material 3210 can be any ferromagnetic material, for example above-mentioned those.In addition, magnetic part preferably can be integrated with in the PCB manufacture craft.Yet the interpolation of magnetic coupling also can be different from the makers' place of PCB and carry out after creating plate.

Figure 33 shows and the similar method of the execution mode shown in Figure 32.Yet, in this execution mode, arranged parallel two signal path 3300 and 3302 on the layer that in PCB 3304, separates.Near signal path 3300 and 3302, bore 3306 holes among the PCB 3304, and fill with magnetic material afterwards.Can settle signal path 3300 and 3302 to make them center on magnetic core, thereby increase the coupling amount that causes by magnetic material.In addition, can use other design to come to increase or reduce the coupling amount according to the requirement of circuit electrical code.Can realize by mask process with core material filler opening 3306.The establishment in PCB hole 3306 and magnetic material are subsequently filled and can be carried out in the PCB manufacture process, though this processing also can be after plate be created and carried out being different from makers' other place of PCB.

The other method that is used to increase mutual induction inductance between the signal path is shown in Figure 34.In the method, in a usual manner signal path 3400 is produced on the PCB 3402.After Making Path, another cover layer of core material internal layer 3404 and PCB material 3406 successively is applied in the top of plate.As a result, magnetic material layer can be embedded in the circuit board.In addition, before applying covering PCB layer 3406, the internal layer 3404 of core material graphically also optionally can be removed.This will make magnetic material only occur in the specific region of the inductance coupling high that needs increase, and also will stop the coupling that is not intended between the unrelated signal path.The establishment of sort circuit need be carried out in the PCB manufactured place, and needs additional process steps so that magnetic material is merged in the entering plate.

All said methods can be used for being increased in the inductance coupling high that PCB makes the unit path in the circuit.These methods help to realize alleviating in the module communication socket at the required crosstalk compensation circuit of the transmission delay effect of upper frequency.
