BOARD-MOUNTED ELECTRICAL CONNECTOR.

摘要

PROBLEM TO BE SOLVED: To enable easy formation of signal patterns with a board-mounted electrical connector without using a multilayer circuit board, and to achieve excellent transmission characteristics and matching of characteristic impedances of transmission signals in the electrical connector. SOLUTION: The board-mounted electrical connector 1 includes signal contacts 4a, grounding contacts 4b, and an insulative housing 6 for holding the signal contacts 4a and the grounding contacts 4b. At least one pair of signal contacts 4a and a grounding contact 4b corresponding to the pair of signal contacts 4a are arranged in two rows at an engagement portion of the insulative hosing 6. Leg portions 5 of the signal contacts 4a and the grounding contacts 4b to be mounted onto a circuit board are arranged in three rows at positions ranging from those closest to an engagement surface of the insulative housing 6 to those farthest from the engagement surface. Leg portions 5b of the grounding contacts 4b are provided in the first row closest to the engagement surface. COPYRIGHT: (C)2006,JPO&NCIPI.
