Technical field
Relate generally to communications connector of the present invention, and more specifically relate to the improvement of returning loss in the HF communication connector.
Background technology
In electrical communication system, sometimes advantageously information signal (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 extend at identical general direction a segment distance and disturbed lead on can not remove with differential.This is called " crosstalking ".Especially, in relating to the communication system of Net-connected computer, form passage by cascade plug, socket and cut cable.In such passage, frequent and the modular jack coupling of modular plug, and the wiring of the electric lead (conductor) in socket and/or the plug also may produce near-end cross (NEXT) (promptly corresponding to crosstalking that the source that is in same position is measured at the input position place).This crosstalks may be 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 is added each internal lead of lead to, then the voltage between lead will remain approximately identical and not have differential crosstalk.
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 5,915,898; 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 more multistage 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.Therefore this idea often can provide two-stage NEXT compensation by one the differential right path in the connector is implemented with respect to another twice intersection in differential right path in the connector.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.
Unfortunately, the introducing of compensate for crosstalk may influence other electrical characteristics negatively.For example, " return loss " and measured plug-socket combination or unshielded twisted pair to the input impedance of (UTP) and 100 ohm matching degree.Realize the acceptable loss performance of returning, particularly the conductor of eight conductor sockets to 1 and to 3 (as in TIA 568B, indicating) go up realize acceptable return the loss performance may because of these two to institute's high crosstalk compensation of requirement but challenging especially typically.Returning loss to 1 may shunt and further deterioration owing to the high electric capacity near property caused of two contact chip (being its " most advanced and sophisticated (tip) " and " ring (ring) ") in plug.For the plug that satisfies or surpass class 6 performance parameters, at crosstalk compensation and return reach between the loss acceptable compromise may be very challenging property, if when particularly wishing that the data transmission bauds on UTP is 10Gb/s in the frequency range of 1-500MHz.
