Patent ID: 8668499

Claim:
A connector to be mounted on a substrate including a first pad and a second pad formed on a surface of the substrate, comprising: a first contact including a first contacting portion to be in contact with the first pad when the connector is mounted on the substrate; a second contact including a second contacting portion to be in contact with the second pad when the connector is mounted on the substrate, wherein the first contact and the second contact being configured such that the first contacting portion slides on the first pad in a first direction while the second contacting portion slides on the second pad in a second direction opposite to the first direction, when the first contact and the second contact are pushed toward the first pad and the second pad, respectively, while the connector is being placed on and fixed to the substrate; a housing, wherein the first contact includes a base portion and the second contact includes a base portion, wherein the base portion of the first contact and the base portion of the second contact are held by the housing to face each other, wherein the base portion of the first contact and the base portion of the second contact are held by the housing not to slide even when the first contact and the second contact are pushed toward the first pad and the second pad, respectively, while the connector is being placed on and fixed to the substrate, wherein the first contact includes an offset portion that shifts the first contacting portion a predetermined amount from the second contacting portion in a third direction which is perpendicular to the first direction and the second direction; a first line of alignment of plural of the first contacts aligned in the third direction with a predetermined pitch P; and a second line of alignment of plural of the second contacts aligned in the third direction with the predetermined pitch P, and wherein the offset portion of each of the first contacts shifts the first contacting portion ½P from the second contacting portion of the corresponding second contact.
