Classification: CPC H | IPC H

Claim 0:
1. An electrical connector which can engage with a corresponding connector inserted from a tip side thereof, comprising:
an insulating housing;
a first contact group constituted of a first plurality of contacts linearly extending along an insertion and extraction direction of the corresponding connector and held by the insulating housing so as to be arranged on a first contact plane;
a second contact group constituted of a second plurality of contacts linearly extending along the insertion and extraction direction of the corresponding connector and held by the insulating housing so as to be arranged on a second contact plane facing the first contact plane; and
a ground plate held by the insulating housing so as to be arranged on a ground plane facing the first contact plane and the second contact plane therebetween,
wherein each of the first contact group and the second contact group contains a signal contact pair for transmitting a differential signal,
wherein each of two contacts constituting the signal contact pair of each of the first contact group and the second contact group has a narrow pitch portion approaching from one of the two contacts toward another one of the two contacts,
wherein the ground plate contains a first ground plate piece and a second ground plate piece located on a base side of the first ground plate piece so that the second ground plate piece is separated from the first ground plate piece and does not contact with the first ground plate piece,
wherein the narrow pitch portion of each of the two contacts constituting the signal contact pair of the first contact group is located between the first ground plate piece and the second ground plate piece in a planar view, and
wherein the narrow pitch portion of each of the two contacts constituting the signal contact pair of the second contact group faces is not located between the first ground plate piece and the second ground plate piece in the planar view.
