At least adjacent conductors (1, 2) are arranged so they wrap around one another at a predetermined distance in their common plane between the insulation piercing connecting devices (11, 12) and the contact springs (21, 22) forming the contact points for compensation of the capacitive and inductive coupling.This avoids crossover and recrossing in different planes, but now a type of crossing is achieved in a plane common to all conductors. In addition, both the capacitive and the inductive coupling can be compensated effectively and equally beyond the 300 MHz range.

The method includes a forward compensation process and a reverse compensation process. The forward compensation process compensates the unbalanced capacitance in the plug of the connector by using the parallel conductive lines or wires. The reverse compensation process can be used to compensate the unbalance capacitance/inductance caused by the forward compensations in the same pair combination of the connector. In both forward compensation and reverse compensation processes, electro-magnetic fields, such as capacitors, can be formed to balance the capacitance/inductance on the printed circuit board of the connector.

The two levels are spaced apart a distance that permits the formation of interacting inductive loops. For at least two pairs of conductors, one of the conductors is in the first lead frame and the other conductor is in the second lead frame, thereby forming two inductive loops which interact with each other to reduce crosstalk. The spring block is made of two substantially identical halves adapted to be latched together to hold the conductors in place.

Circuit board space requirements are minimized by arranging the terminal tails of both groups of terminals in a single line.

Abstract: Electrical connector 10 is used to terminate individual wires 6, 8 in two twisted wire pairs 2, 4. The connector includes an insulated housing with terminals 50 located in terminal receiving cavities 34 in the housing. The terminals 50 are inclined relative to parallel wire receiving channels 34 and paired terminals 50 for terminating individual wires of a the same twisted wire pair, 2 or 4 are spaced closer together than adjacent intermediate terminals associated with different wire pairs. Pairing inclined terminals 50 increases the coupling between wires in the same wire pair and increasing the spacing between terminals of different wire pairs reduces the capacitive cross talk between adjacent wire pairs. High frequency performance of the electrical connector 10 is thereby increased. A central cavity between terminal pairs increases the effective dielectric constant to further reduce crosstalk.

The compensating insert includes a dielectric substrate which carries conductive traces, and the traces are arranged to be connected to selected ones of the wires.

Abstract: Crosstalk compensation is achieved by connecting coupling devices (e.g., capacitors) between different pairs of conductors of a multi-pair connector. The coupling devices are selected to offset both differential-to-differential coupling as well as differential-to-common-mode coupling that would otherwise occur between pairs of conductors when one of the conductor pair is driven with a differential signal. The present invention can be used to achieve both differential and common-mode crosstalk compensation without relying on conductor crossover techniques.

Abstract: Electrical connectors for electrically and physically connecting cable conductors to mating connectors frequently require precise and demanding assembly in order to produce a required level of crosstalk. In many instances, this level must be a set amount, rather than the lowest level possible, in order to match a canceling crosstalk being produced in the mating connector. The present invention is a crossover lead frame connector which reduces the demands upon the assembler in assembling the connector and cable, and yet still provides the precise level of crosstalk required in the connector. These advantages are realized by the use of a crossover lead frame structure which controls the physical length and routing of the signals between the cable conductors and connector pins. This allows the manufacturer to match the connector to the layout of the cable conductors and fix the level of crosstalk that will be produced at the time the connector is manufactured.

In one embodiment, the inner contour of the mandrel is configured to form a first bend radius in the terminal wires at a side of the wire board from which the wires emerge, and to form a second bend radius in the terminal wires with which the wires angle back over an opposite side of the wire board to contact the mating connector.

The connecting conductors 3 are arranged in three layers in such a position relationship that can prevent them from short-circuiting each other and also can prevent a crosstalk from being produced between them. In this structure, the connecting conductors 3 are arranged in two or more levels, which makes it easier for the connector to be designed for prevention of the crosstalk when compared with a structure in which the connecting conductors 3 are arranged in one plane.

Abstract: A communication connector having a plurality of contact pairs for conductive connection to respective communication signal wire pairs is provided with a capacitor label that capacitively couples a first contact of one contact pair to a second contact of a second contact pair to reduce near end cross talk between adjacent contacts.
