Abstract: A multilayer circuit board includes a plurality of electrically conductive rear pads for termination of a plurality of wires and a plurality of electrically conductive front pads for insertion into a connector. A plurality of pairs of substantially parallel traces extend between and connect the front pads to the rear pads. At least a first pair of traces and the front and rear pads connected thereto are disposed in a same layer of the multilayer circuit board. At least a second pair of traces is disposed in a same layer, and the rear and front pads connected thereto are disposed in a different layer of the multilayer circuit board. At least a third pair of traces are disposed in different layers of the multilayer circuit board. For each trace extending between and connecting the front and rear pads corresponding to the trace, the trace comprises no more than two vias.

Abstract: A connector assembly includes, a housing, a circuit board that includes a conductive front pad and a conductive rear pad electrically connected to the front pad, and a cable that includes an insulated conductor having a conductor surrounded by an insulating material. The conductor has a diameter not greater than 24 AWG. The uninsulated front end of the conductor is terminated at the rear pad and includes a preformed bend. The connector assembly also includes a recess formed in an external surface and on a lateral side of the housing. The recess is designed to receive and house a spring member of a pull tab that is assembled to the housing. The vertical separation between the recess and the circuit board is h, the average thickness of the cable is t, and h≥3t. The preformed bend may include first and second portions connected by a substantially flattened joint.

Abstract: A connector assembly includes first and second connectors. Each connector includes a plurality of terminals A1 through An, n is an integer≥2, sequentially arranged in a row. The connector assembly also includes a flat cable that includes a plurality of electrical conductors electrically connecting the terminals of the first and second connectors. For each i from 1 to n, terminal Ai of the first connector is electrically connected, via a different electrical conductor of the cable, to the terminal Ai of the second connector. The cable includes a bend greater than about 150° around at least two fold lines that extend across the entire width of the cable. Each of the first and second connectors is configured to mate with the same mating connector, such that when each of the first and second connectors mates with the same mating connector in a same plan view, the An terminals are both either on a left or a right side of the A1 terminals.
