摘要： A connector includes multiple pairs of signal contacts arranged in a housing, and facilitates the wiring design and the wiring operation for substrates. The two signal contacts in each of the multiple pairs are arranged at a distance in the longitudinal direction of the housing. With this arrangement, excellent coupling can be established between the two signal contacts, and signals can be balanced-transmitted without causing a phase difference. Also, the lengths of each pair of wires of a wiring substrate to be connected to the multiple pairs of signal contacts can be easily made uniform. Accordingly, there is no need to prepare excessive wiring areas, and the substrate wiring design and the wiring operation can be simplified.

摘要： A connector assembly including a jack connector and a plug connector. Each of the jack and plug connectors includes plural pairs of signal contact elements, the pairs being arranged parallel with each other in an array, and the signal contact elements of each of the pairs being arranged opposite to each other; plural ground contact elements, each of which is used as a shield to reduce crosstalk between two parallel the pairs of signal contact elements arranged side by side, the plural pairs of signal contact elements and the plural ground contact elements being alternately arranged in a row; and an electro-insulating body for supporting the signal contact elements and the ground contact elements in a mutually insulated arrangement. It is advantageous that each pair of signal contact elements is used for a balanced transmission line.
