A modular jack connector mounted on a main printed circuit board and having a receptacle into which a modular plug of an electronic component is inserted. The connector includes a housing, a first set of contacts arranged in the housing each adapted to engage one of the contacts of the plug, a second set of contacts at least partially arranged in the housing and adapted to engaging the main printed circuit board, contact coupling circuit means for electrically coupling the first and second sets of contacts, a capacitor for providing impedance to high frequency noise and interference and a metallic shield at least partially surrounding the housing and connected to a grounding region on the main printed circuit board. In one embodiment, the capacitor is a flexible laminate assembly including first and second conductive sheet members and an intermediate insulative material. Further, the capacitor has a plurality of folded pleats including a first pleat arranged at one end of the laminate assembly and a second pleat arranged at an opposite end of the laminate assembly. The first conductive sheet member is electrically coupled at the first pleat to the contact coupling circuit means, and the second conductive sheet member is electrically coupled at the second pleat to the metallic shield to thereby ground the first set of contacts through the capacitor. The contact coupling circuit means may include toroidal coil pairs which function separately as either a differential mode filter or a common mode filter.

A modular plug and multi-pair cable assembly provides reduced near-end crosstalk between two signal pairs of the cable. A modular plug has a plurality of wire-receiving passages disposed in first and second planar arrays spaced one above the other, with the passages of one planar array being staggered in position with respect to the passages of the other planar array. An end of a first wire of each of two signal pairs is received in respective wire-receiving passages of the first planar array and an end of a second wire of the two signal pairs is received in respective wire-receiving passages of the second planar array. A first pair plane in which the wire ends of the first signal pair are situated intersects a second pair plane in which the wire ends of the second signal pair are situated. In this manner crosstalk between the two signal pairs resulting from magnetic and electric field coupling is reduced.

An electrical device for surface mounting on a circuit board comprises a housing and a plurality of contacts wherein the distance between the region at which the pad-engaging portion of each contact engages its respective pad, and the region of the fulcrum about which the contact deflects, is maximized to reduce the magnitude of the biasing force resulting from the deflection. An improved mounting component for the device comprises a post having tangs that extend from its side which are deflected to allow the post to be inserted into the board opening and which skive into the sides of the opening to prevent the post from retraction therefrom. An improved positioning arrangement for the device comprises a pair of positioning posts having polygonal cross-sections, each having a maximum cross-sectional dimension in single, mutually orthogonal, directions.

A cable ready connector comprises a housing including a conductor holding member and a plurality of contact terminals for effecting insulation displacement engagement with respective ones of the cable conductors. Each of the contact terminals includes at least first and second insulation displacement sections capable of engagement with conductors having diameters within first and second ranges respectively. The connector housing also comprises a load bar for holding portions of the conductors in two groups situated in spaced parallel planes, the conductors in one group being staggered with respect to the conductors of the other group.
