Abstract: In an electrical connector wherein signal transmission paths 53 have signal connecting portions 53 C soldered to signal circuit units on a circuit board, ground members 54, 55 have ground connecting portions 54C, 55C soldered to ground circuit units on the circuit board, and the ground connecting portions 54C, 55C are positioned in the arrangement direction of the signal transmission paths 53 between the signal connecting portions 53C of adjacent signal transmission paths, a width range WG between the opposite end locations of the ground connecting portions 54C, 55C of the ground members 54, 55 in the width direction, which is parallel to the mounting surface of the circuit board and perpendicular to the arrangement direction, extends beyond the width range WS of the signal connecting portions 53C of the signal transmission paths 53.

Abstract: The signal transmission paths are transmission path pairs 22, 24 located spaced apart in the arrangement direction of the signal transmission paths 22, 24, the transmission path pairs 22, 24 have two types of pairs, straight pairs 22 and cross pairs 24, the straight pairs 22 and the cross pairs 24 are alternately disposed in the arrangement direction, the signal transmission paths arranged in the arrangement direction form signal transmission path rows, a plurality of the signal transmission path rows are provided, and of two adjacent signal transmission path rows, at least a part of the transmission path pairs 22, 24 of one signal transmission path row in the height direction is offset in the arrangement direction with respect to the transmission path pairs 22, 24 of the other signal transmission path row.

Abstract: Blades 20A to 20D are formed such that arm portions 31A to 31D of electroconductive elongated members 30A to 30D are retained in place with the help of insulating plates 50A-1 to 50D-2, a housing 10 has formed therein holding portions 17A to 17D allowing for the above-mentioned blades 20A to 20D to be inserted from the rear, said holding portions 17A to 17D have formed therein guiding portions 17A-1 to 17D-1 guiding the insertion of the above-mentioned blades 20A to 20D from the rear with the help of guiding grooves 17A-3 to 17D-3 extending in the forward-backward direction, and movement of the above-mentioned blades 20A to 20D in the up-down direction within the guiding grooves 17A-3 to 17D-3 is restricted.

Abstract: Blades 60A, 60B are formed due to the fact that arm-portion blades 60A-1, 60B-1, by which arm portions of electroconductive elongated members are retained in place, and leg-portion blades 60A-2, 60B-2, by which leg portions are retained in place, are coupled via bend portions of the electroconductive elongated members such that the respective major faces of the blades form an angle with one another, a housing 10 has formed therein a holding portion 10G holding the blades 60A, 60B, said holding portion 10G has formed therein restricting portions 17K, 17J positioned in a face-to-face relationship with the front faces of the leg-portion blades 60A-2, 60B-2 in front of said leg-portion blades 60A-2, 60B-2, and said restricting portions 17K, 17J can restrict forward displacement of the leg-portion blades 60A-2, 60B-2.

Abstract: An electric connector assembly includes an intermediate connector for connecting the first attaching connector to the second attaching connector. The intermediate connector includes a power source terminal. The first attaching connector includes a first receiving terminal for contacting with the power source terminal, and the second attaching connector includes a second receiving terminal for contacting with the power source terminal. One of the first receiving terminal and the power source terminal and one of the second receiving terminal and the power source terminal include a metal cylindrical member capable of elastically deforming in a radial direction. Therefore, the power source terminal can incline and move in the radial direction at an arbitrary angle along a circumferential direction around an axial line of the power source terminal.
