A printed circuit card having a printed circuit board therein with ground contact pads. The printed circuit card is made of a conductive housing in which the printed circuit board resides. At least one ground contact clip is interfaced with both the ground contact pad on the printed circuit board and the conductive housing to complete a ground circuit for the printed circuit board and for protecting the connector against electromagnetic interference and electrostatic discharge. The ground clip further ensures that the printed circuit card has a high ground-to-signal ratio, thereby ensuring good data transmission through the card.

Also disclosed is the method of fabricating the electrical connector.

Multiconductor flat cable connector, apparatus and method

Microstrip transmission of electrical signals between two arrays of signal conductors such as two printed circuit boards is maintained in an electrical connector in which signal contacts are disposed on opposite sides of the central ground bus. Signal contacts are urged inwardly into engagement with a central dielectric wall and a ground bus is similarly urged outwardly into engagement with the same wall to establish the microstrip configuration between each row of terminals in the central ground bus. The receptacle connector includes a right angle bend and signal contacts as well as the ground bus also have a right angle bend. The insulative housing of a right angle connector comprises upper and lower housing members which are snapped into engagement. Resilient arms, forming a part of the connector mounting assembly on the upper housing member, engage the lower housing member to hold it in place.

A connector, a termination of a conductor to a ground bus in a connector, and a method for effecting the termination is disclosed. The ground bus includes a series of openings in one edge thereof, each having a pair of parallel walls that are spaced apart a distance greater than the diameter of the conductor to be terminated. Each opening includes a constriction which positions and holds the conductor so that it is spaced from the walls of the opening during the soldering operation.

Apparatus for terminating a ribbon cable formed of electrical conductors in a web of electrical insulation during the attaching thereof to a connector. The apparatus comprises a guide member releasably coupleable with the cable at a predetermined location with respect to the end of the cable. The apparatus also comprises means to sequentially couple the guide member and cable end in operative relationship with a series of processing stations whereat the guide member functions to accurately locate the cable end with respect to the operating mechanisms of the processing stations. Such processing stations are operative for the attaching of the cable end to a connector. Also disclosed is the method of terminating a ribbon cable with such apparatus.

The connector comprises a housing formed with a longitudinal central slot adapted to receive an electrically conductive ground bus. The upper end of the bus is adapted to retain stripped ground wires of the flat cable by crimping and soldering. The lower end of the bus is adapted to be received within the mating connector.

Electrical cable connector and method of use

A twisted pair flat cable suitable for use in undercarpet environments is disclosed. A plurality of twisted pairs are positioned side-by-side, each in separate compartments formed within a hollow envelope of an extruded outer sheath. Separator ribs which do not extend across the entire height of the sheath prevent lateral movement of twisted pairs out of their respective compartments. By cutting the outer sheath at only one location, the outer sheath can be folded back to deploy the twisted pairs for termination. Laterally adjacent solid members suitable for withstanding compressive loads can be employed with a centrally disposed sheath.

Low profile cables for twisted pairs

Apparatus for bending or deploying selected, individual, stripped, electrical wires at the stripped free end of a ribbon cable. The apparatus comprises a base having a box-like recess with fixed components or plate-like members or shims to individually position the wires to be bent. The fixed components include tall positioning shims with notches extending downwardly to contact the insulating web of a ribbon cable between its stripped wires and to properly position the web and the wires. The fixed components also include short ground wire shims located between some of the tall positioning shims for receiving, thereadjacent, ground wires of the received ribbon cable. The fixed components also include short signal wire shims located between others of the tall positioning shims for receiving, thereadjacent, signal wires of the received ribbon cable. Also included within the apparatus are bending fingers operatively associated with the fixed components for reciprocal movement with respect thereto. The bending fingers are located in two rows on opposite sides of the notches, ribbon cable and wires for movement from retracted positions to advanced positions wherein the leading edges of the bending fingers contact and bend selected, individual stripped signal wires of the ribbon cable supported by, and positioned in, the fixed components.
