Differential signal connector capable of reducing skew between a differential signal pair

摘要

A differential signal connector includes a plurality of pairs of signal contacts, a plurality of ground contacts, and an insulating housing holding the signal contacts and the ground contacts. On a first connection side for connection to a connection partner, the ground contacts are arranged on both sides of each pair of signal contacts so that a contact array of a fixed pitch is formed. On a second connection side for connection to a board, the ground contacts are arranged spaced apart from each other in a first row, while the pairs of signal contacts, which are adjacently arranged on both sides of the ground contact on the first connection side, are arranged so as to be allocated in a second row and a third row located on both sides of the first row so that the pairs of signal contacts are arranged zigzag on the second connection side.

主权项

1. A lead frame as an intermediate member for forming a contact group of a connector, comprising a plurality of first leads arranged on a plane, second leads arranged on the plane so as to form a pair between the first leads, and a connecting portion connecting the first leads and the second leads on a first end side, wherein the leads of the pair of second leads are separated by a first distance on the first end side and by a second distance on a second end side opposite the first end side, the second distance being greater than the first distance,
wherein the first leads each have a first straight portion extending from the connecting portion, a first offset portion extending obliquely from the first straight portion so as to be away from the second lead, and a second straight portion extending from the first offset portion in the same direction as the first straight portion; and wherein the first leads each have, in the second straight portion, a first bending intended portion for bending in a direction crossing the plane, and wherein the second leads each have, at a position between a portion on the second end side and the connecting portion, a second bending intended portion for bending in the direction crossing the plane.
