Abstract

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.

First claim

What is claimed is:

1. A connector comprising a plurality of ground contacts arranged at an interval from each other and a plurality of signal contacts arranged so as to form pairs each between the ground contacts,
wherein one end of each of the ground contacts and one end of each of the signal contacts are adjacently arranged in a same plane on a first connection side of the connector,
wherein the ground contacts and the signal contacts extend in parallel to each other from the other ends and then are bent at a right angle in the same direction to have bent portions upward at positions offset between each of the ground contacts and each of the signal contacts,
wherein, on a second connection side at the other ends of the connector, the ground contacts and signal contacts are arranged in the form of a trapezoid so that adjacent ones of the ground contacts are located at both ends of a long side of the trapezoid while the signal contacts forming each pair are located at both ends of a short side of the trapezoid,
wherein, the signal contacts forming each pair are bent outward away from each other in the vicinity of the second connection side, and
wherein each of the ground contacts has two offset portions, only one of the two offset portions being formed between a corresponding one of the bent portions and the second connection side.
