In an electrical connector wherein signal transmission pathshave signal connecting portionsC soldered to signal circuit units on a circuit board, ground membershave ground connecting portionsC,C soldered to ground circuit units on the circuit board, and the ground connecting portionsC,C are positioned in the arrangement direction of the signal transmission pathsbetween the signal connecting portionsC of adjacent signal transmission paths, a width range WG between the opposite end locations of the ground connecting portionsC,C of the ground membersin 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 portionsC of the signal transmission paths

Electrical connector and electrical connector with circuit board

The signal transmission paths are transmission path pairslocated spaced apart in the arrangement direction of the signal transmission paths, the transmission path pairshave two types of pairs, straight pairsand cross pairs, the straight pairsand the cross pairsare 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 pairsof one signal transmission path row in the height direction is offset in the arrangement direction with respect to the transmission path pairsof the other signal transmission path row.

BladesA toD are formed such that arm portionsA toD of electroconductive elongated membersA toD are retained in place with the help of insulating platesA-toD-, a housinghas formed therein holding portionsA toD allowing for the above-mentioned bladesA toD to be inserted from the rear, said holding portionsA toD have formed therein guiding portionsA-toD-guiding the insertion of the above-mentioned bladesA toD from the rear with the help of guiding groovesA-toD-extending in the forward-backward direction, and movement of the above-mentioned bladesA toD in the up-down direction within the guiding groovesA-toD-is restricted.

Right-angle electrical connector

BladesA,B are formed due to the fact that arm-portion bladesA-B-, by which arm portions of electroconductive elongated members are retained in place, and leg-portion bladesA-B-, 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 housinghas formed therein a holding portionG holding the bladesA,B, said holding portionG has formed therein restricting portionsK,J positioned in a face-to-face relationship with the front faces of the leg-portion bladesA-B-in front of said leg-portion bladesA-B-, and said restricting portionsK,J can restrict forward displacement of the leg-portion bladesA-B-

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. The elastic cylindrical member includes a circumference elastically contacting with the power source terminal, the first receiving terminal, and the second receiving terminal.
