Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A connector for end terminating and/or daisy chaining flat multiconductor cable. The connector includes components for positioning a pair of first and second flat cables in substantially overlying relationship so that conductors of the second cable are situated essentially between pairs of adjacent conductors of the first cable. A plurality of first contacts engage the conductors of the first cable. A plurality of second contacts pierce the webs of insulation between adjacent pairs of conductors of the first cable and engage the conductors of the second cable.

Abstract: An electrical connection system including a plug-in connector housing for receiving a plurality of electrical signal wires, a plurality of connector contacts retained by the housing, a header body for receiving the connector housing, a plurality of header contacts retained by the body and each positioned so as to engage one of the connector contacts upon reception of the connector housing by the header body, connector keying means selectively disposed at any of a plurality of predetermined positions on the housing, and header keying means selectively disposed at any of a plurality of given positions on the header body and each corresponding to one of the predetermined positions on the connector housing.

Abstract: A connector for terminating flat ribbon cable composed of flexible electrical insulation and retaining a plurality of electrically isolated, parallel conductors. The connector includes a housing that defines a slot for receiving an end of a flat ribbon cable to be terminated and comprises a base that defines a row of contact receptacles extending transversely to the slot and aligned with individual conductors in the cable. Also comprising the housing is a cover adapted for mating engagement with the base and defining catch wall portions extending transversely to the cable slot. Retained by each of the receptacles is a contact having a head portion having cutting edges shaped and arranged to receive and penetrate the insulation surrounding a different conductor in the cable and to make electrical contact therewith. The contacts also include latch portions for engaging and fastening the cover of the housing to the base.

Abstract: Disclosed is an electrical connector composed of a dielectric housing that defines an internal cavity, cable openings for receiving the ends of a pair of flat ribbon cables with alternating ground and signal wires, and conductor openings for receiving conductor elements to be connected to the conductive wires in the flat cables. Located in the cavity is a first grounding bus for electrically connecting together the alternate ground wires in one of the cables and a second grounding bus for electrically connecting together the alternate ground wires in the other cable. Also retained within the cavity are a plurality of electrically isolated coupling elements each operative to electrically connect one of the conductor elements with a different one of the alternate signal wires in the two cables. Finally a ground output means connects the first and second grounding busses to at least one conductor element so as to connect all of the ground wires to a circuit common outside the connector.
