Embodiment Construction

[0045] The present invention relates to an improved set of connectors, particularly for enhancing the performance of high-speed cables in input-output ("I / O") applications and other types of applications. More specifically, the present invention seeks to impose a measure of mechanical and electrical consistency in the end regions of the connector to improve the performance of the connector when combined with an opposing or mating connector.

[0046] Many peripherals associated with electronic devices, such as video cameras or camcorders, transmit digital signals at multiple frequencies. Other devices associated with the computer, such as its CPU section, operate at high speed for transferring data. High-speed cables are used to connect these devices to the CPU, and can be in some applications where two or more CPUs are connected together. Certain cables may be sufficiently constructed for carrying high-speed signals and may include differential signal wire pairs, each pair be...

Abstract

A terminal contact arrangement for a connector promotes reduction in deviation of the impedance of the connector when mated to an opposing connector and energized. The connector has an insulative housing with a plurality of terminal-receiving passages disposed in it. Conductive terminals are supported in some, but not all of the passages. The terminal contain distinct terminal sets that include a pair of differential signal terminals and at least two associated ground reference terminals. The two associated ground reference terminals are interconnected together so that electrically, they act as a single ground terminal having a width equal to the sum of the widths of the two connected ground reference terminals. The ground reference terminals of the sets are disposed in a single row of terminals, while the differential signal terminals of the same terminal set are disposed in another row of terminals spaced apart from the row of ground reference terminals. The differential signal terminals are separated from each other within their terminal row by an empty passage so that the two differential signal terminals of each terminal set are spaced farther apart from each other than they are spaced apart from their associated ground reference terminals.

Description

technical field [0001] The present invention relates generally to terminations for connectors, and more particularly to connectors having selected impedances for connecting signal cables such as in automotive environments. Background technique [0002] Many electronic devices rely on transmission lines to transmit signals between related devices or between peripheral devices and computer circuit boards. These transmission lines incorporate signal cables capable of high-speed data transmission. [0003] These signal cables may consist of one or more twisted pairs known to be twisted together along the length of the cable, each such twisted pair being surrounded by an associated ground shield. These twisted pairs typically receive complementary signal voltages, i.e. one wire of the twisted pair sees a +1.0 volt signal while the other of the twisted pair sees a -1.0 volt signal. These wires can therefore be called "differential" pairs, a term that refers to the voltage differ...
