A connector for establishing electrical connections with a PCB comprises first and second sets of contact pads arranged in first and second rows on a same surface of the PCB. The connector includes a first set of elongated contacts, a second set of elongated contacts, and a contact block. The first set of contacts have contact surfaces that form a first row of contact surfaces configured to make and break electrical connectivity with the first set of contact pads of the PCB. The second set of contacts have contact surfaces that form a second row of contact surfaces configured to make and break electrical connectivity with the second set of contact pads of the PCB. The contact block supports the first and second sets of contacts and causes the contact surfaces to wipe against the first and second sets of contact pads when making and breaking electrical connectivity therewith.

A connector assembly for electrically connecting a plurality of wires to a circuit board is described. The connector assembly includes a vertical connector that includes an insulative base having pluralities of substantially parallel first and second base channels formed on respective opposing first and second major surfaces of the base. The vertical connector further includes pluralities of first and second terminals in registration with the respective first and second base channels, each first and second terminal including a contact portion for making contact with a wire, and a press-fit portion for being inserted into a conductive via of a circuit board. At least a majority length of each first and second terminal is disposed outside the housing. Each first and second terminal is secured in the connector at least in part by virtue of making physical contact with a corresponding wire.

Connector assembly

Various high speed shielded cables are used in combination with a connector assembly. The connector assembly includes a plurality of electrical terminations in electrical contact with the conductor sets of the cable at a first end of the cable, the electrical terminations configured to make electrical contact with corresponding mating electrical terminations of a mating connector and at least one housing configured to retain the plurality of electrical terminations in a planar, spaced apart configuration.

Connector arrangements for shielded electrical cables

A shielded electrical ribbon cable is disclosed. The cable includes a plurality of conductor sets including a first conductor set adjacent a second conductor set. Each conductor set includes one or more insulated conductors. The cable further includes first and second shielding films disposed on opposite sides of the cable forming cover portions and pinched portions, where the cover portions substantially surround each conductor set, and the pinched portions form pinched portions of the cable on each side of each conductor set. The insulated conductors in a conductor set are not in a same geometrical plane. A first insulated conductor of the first conductor set is nearest the second conductor set. A second insulated conductor of the second conductor set is nearest the first conductor set. The first and second insulated conductors have a center-to-center spacing S. The first insulated conductor has an outer dimension Dand the second insulated conductor has an outer dimension D. S/Dmin is in a range from 1.7 to 2, where Dmin is the lesser of Dand D

An electrical connector includes a plurality of electrical cable terminations for mating with a corresponding plurality of contact pins and a planar insulative connector body. Each of the electrical cable terminations includes a tubular housing, an inner housing, and at least one electrical contact. The tubular housing is of electrically conductive material and has inner walls defining an opening and first and second opposed open ends. The inner housing is of electrically insulating material and is inserted into the tubular housing from at least one of the open ends thereof. The inner housing comprises at least one inner space configured to receive an electrical contact in a fixed relative position. The electrical contact is positioned in the inner housing and configured to be connected to an electrical cable. The planar insulative connector body has an upper surface and an opposing lower surface. The upper and lower surfaces are defined by a front edge, a back edge, and two longitudinal side edges. The upper surface includes a plurality of longitudinal channels. Each channel contains one of the plurality of electrical cable terminations. The front edge of the connector body has a plurality of openings for guiding the contact pins into the mating electrical cable terminations positioned within the channels. An electrical connector assembly may include a plurality of the electrical connectors secured in a stacked configuration.

Electrical connector assembly and system

A shielded electrical cable is disclosed that includes a plurality of spaced apart conductor sets where each conductor set includes one or more insulated conductors. The cable further includes first and second shielding films that include concentric portions, pinched portions, and transition portions arranged such that the concentric portions are substantially concentric with one or more end conductors of each conductor set, the pinched portions form pinched portions of the cable on two sides of the conductor set, and the transition portions provide gradual transitions between the concentric portions and the pinched portions. The cross-sectional areas of the transition portions are less than the cross-sectional areas of the conductors. The radius of curvature of the shielding films in the transverse direction is at least 100 microns.
