Technical field
Relate generally to communications connector of the present invention, and the near-end cross (NEXT) that more specifically relates in communications connector compensates.
Background technology
In electrical communication system, sometimes advantageously information signal (for example video, audio frequency, data) is gone up transmission in couple of conductor (being called " lead to " or " differential to " hereinafter) but not transmit on single lead, wherein Chuan Shu signal comprises the voltage difference between the lead and does not consider the existence of absolute voltage.Each internal lead of lead is easy to pick up electrical noise from for example source of lightning, automobile spark plug and radio station etc.Because this noise like is identical to two internal leads of lead, differential wave is typically not disturbed.This is to the fundamental cause near layout with differential.
Yet what more be concerned about is the electrical noise to picking up near lead or lead, near lead this or lead to may identical general direction extend long distance and disturbed lead on can not remove with differential.This is called differential crosstalk.Especially, in the communication system of the modular plug that often uses with computer and modular jack coupling, the electric lead (conductor) in socket and/or the plug also may produce near-end cross (NEXT) (promptly corresponding to the source that is in same position crosstalking in the measurement of input position place) therein.This crosstalks from the lead of the location of the next-door neighbour in the short distance.In situation more than all, have undesirable signal in electric conductor, it may the interfere information signal.As long as identical noise signal adds each internal lead of lead to, then the voltage between lead will remain on to approximately identical and do not have a differential crosstalk.
Crosstalking to be categorized as differential crosstalk, and as previously discussed, wherein crosstalk signal is rendered as the voltage difference between differential right two conductors, or common mode crosstalk, and wherein crosstalk signal is rendered as for differential two right conductors identical.Differential crosstalk that presents in communication port or common mode crosstalk may be derived from the source with differential mode or common mode attribute.
Authorize people's such as Adriaenssens US Patent No 5,997,358 (being called " patent 358 " hereinafter) were described the two-step scheme that is used to the differential differential NEXT of arriving of plug-socket combined compensation, and (complete content of patent 358 merges by reference at this, same with reference to merging US Patent No 5,915,989; No 6,042, and 427; No 6,050, and 843; With No 6,270,381).The connector of in patent 358, describing can by usually in socket one-level or two-stage place add make or artificial crosstalking reduce in the modular plug electric lead between inside NEXT (original crosstalk), therefore eliminate or reduced always crosstalking of plug-socket combination.Crosstalking of making is called compensate for crosstalk at this.This idea often can be by implementing one the differential right path in the connector with respect to another twice intersection in differential right path in the connector, therefore for to relation being provided two-stage NEXT compensate.This scheme can more effectively reduce NEXT than the scheme of wherein adding compensation at single level place, particularly when second level compensation and compensation subsequently grade comprise time delay, time delay consider offend crosstalk and compensate for crosstalk between phase difference select.This type of layout can comprise capacitive and/or the inductive element of having introduced multipole crosstalk compensation, and typically use in jack lead frames and socket in the PWB structure in.These structures can allow connector to satisfy in ANSI/EIA/TIA 568 " class 6 " performance standard of regulation, this standard be about the plug and socket of coupling for critical piece standard until the 250MHz transmission frequency.
External NEXT is the differential crosstalk that occurs between the communication port.Obvious, the physical separation between socket is with helpful and/or can use the solution of typically crosstalking.Yet problem condition may be to crosstalk in " to 3 " of " to 3 " and another passage of a passage, though to 3 plug and socket leads in each passage mutually away from and unique coupling occur between the cable of wiring.For reducing the external NEXT of this form, can use the shielding harness of the twisted-pair feeder structure that comprises Shielded Twisted Pair or band paper tinsel.Yet, comprise that shielding part may increase the cost of system.Another solution of reducing or minimizing external NEXT utilized cable in passage apart and/or the apart between the socket in passage.Yet this is unpractiaca typically, because the boundling of cable and patch cord retrains and be easy to conductor arrangement but convention because of " space ".
Although in improving matching connector (being plug-socket) performance, realized progress rapidly recently, and particularly reduced (the 500MHz for example of crosstalking under the frequency that raises, see the U.S. Patent application No 10/845 of " the NEXT High Frequency Improvement byUsing Frequency Dependent Effective Capacitance " by name that submitted on May 4th, 2004,104, it is disclosed in this by with reference to merging) in realized progress rapidly, but the connector of the teaching of these teachings of many dependences or patent ' 358 may (for example, still have the external NEXT of unacceptable height under 500MHz) in very high frequency.Therefore, hope provides the connector that has the external NEXT of reduction under very high frequency.

Forward accompanying drawing now to, Fig. 1 illustrates the typical wiring topology for the communication plug 10 of the prior art with four pair twist zygonema 20a, 20b, 22a, 22b, 24a, 24b, 26a, 26b.Plug bond standard as routine according to TIA 568B, lead is in the center (being connected to sheet 12a, 12b) of plug 10 to 1 ( lead 20a, 20b), lead has occupied the right side (being connected to sheet 14a, 14b) of joint 10 to 2 (lead 22a, 22b), lead has occupied the left side (being connected to sheet 18a, 18b) of joint 10 to 4 (lead 26a, 26b), and lead has striden across lead to 1 (being connected to sheet 16a, 16b) to 3 ( lead 24a, 24b).Routinely, right each of these leads is stranded, makes that the laying length of the twisted wire that these are right is different slightly.Because lead strides across lead to 1 to 3, the ring (ring) (being sheet 16a and lead 24a) of the tip to 3 (tip) (being sheet 16b and lead 24b) comparison 3 is more approaching to 2 conductor 22a, 22b and sheet 14a, 14b (particularly in the zone of sheet).Similarly, sheet 16a and lead 24a are more approaching to 4 conductor 26a, 26b and sheet 18a, 18b, particularly in the zone of sheet than sheet 16b and lead 24b.Therefore, sheet 16a, the 16b to 3 and lead 24a, 24b are spatially with respect to holding to 2 and 4 imbalances, particularly in plug blades and the zone near sheet.
This non-equilibrium typically from the contact point of gang socket by plug blades be connected lead and get back in the plug 10 and take place effectively.Nonequilibrium amplitude depends on that lead 24a, the 24b to 3 keeps distance separately before turning back to as the twisted configuration of twisted-pair feeder feature in plug 10.(a) to 3 and to 2 and (b) to 3 and to 4 between non-equilibrium may be in plug 10 difference mode signal on will be to 3 be converted to 2 and to 4 on common mode crosstalk.Take place though this conversion from the differential mode to the common mode crosstalk may be crossed the frequency band that is lower than 250MHz, as a result of the external NEXT of the passage that is generated is typically minimum.Yet, find in conjunction with the present invention, under the transmission frequency (for example until 500MHz) that raises, differential mode may have the big injurious effects of being on close level to the external NEXT of passage to the conversion of common mode crosstalk, and passage satisfies the ability of FCC emission level may be limited, particularly under the transmission frequency that raises.
Typically the non-equilibrium of experience can solve by plug of the present invention in conventional plug 10, and embodiments of the invention illustrate in Fig. 2 to Fig. 9.Compare with the connector of prior art, these plugs may reduce the differential mode that the taken place conversion amount to common mode crosstalk substantially.Generally speaking, found can realize better external NEXT performance to the conversion of common mode crosstalk, particularly under the frequency (that is, being higher than 250MHz) of rising by reducing differential mode in the plug.
With reference now to Fig. 2,, wherein illustrates the embodiment that stylizes that is designated 30 plug of the present invention widely.Plug 30 comprises eight sheet 32a, 32b, 34a, 34b, 36a, 36b, 38a, 38b and eight conductor 40a, 40b, 42a, 42b, 44a, 44b, 46a, 46b, eight conductors be twisted into to and be attached to sheet in the identical pairing, such as above plug 10 for Fig. 1 elaboration.Especially, the conductor to 3 (being conductor 44a, 44b) is arranged so that behind first crosspoint 45 in adjacent sheet zone, and conductor 44a, 44b are formed on the expanded loop 48 that second crosspoint 52 (take place to 3 conductor typically stranded) is located to stop herein.Expanded loop 48 comprises and is respectively adjacent to conductor to 2 ( conductor 42a, 42b) and conductor section 50a, the 50b to 4 (conductor 46a, 46b) location, and section 50a, a 50b separate 1 ( conductor 40a, 40b) with conductor.In this structure, can overcome by sheet and be attached to that the position of the lead of sheet causes (a) to 2 and to 3 and (b) to 3 and to 4 between the space non-equilibrium.As a result of, can prevent or reduce differential crosstalk in the plug 10 usually occur in Fig. 1 substantially, consequently can improve the external NEXT performance of plug 30 to the conversion of common mode crosstalk.
