Electrical connector with high performance contacts

An electrical connector for electrically connecting a mating component to a printed circuit board comprising:

• an insulative hosing;
• a plurality of electrical contacts accommodated in the housing;
• each contact defining a base portion, a fastening portion accommodated in the housing, a spring arm extending from the base portion, and a soldering portion connecting to the printed circuit board, and the spring arm further defining an extending beam and a contacting portion;
• wherein
• an extending direction of the extending beam is deflective from an extending direction of the contacting portion on a plane parallel to the mating component, wherein the extending beam defines a first axis and the contacting portion defines a second axis, and the first axis is deflective from the second axis on planes parallel and perpendicular to the printed circuit board.

An electrical connector assembly comprising:

• an electronic package with a plurality of conductive pads on an underside thereof;
• an insulative housing defining a plurality of passageways therein;
• a plurality of contacts disposed in the corresponding passageways, respectively, each of said contacts including:
• an extending beam extending upwardly and in a direction from a top view;
• and
• a contact region located above an upper portion of the extending beam, and including thereof at least one portion extending upwardly and in another direction oblique to said direction from the top view,
• said contact region extending above a top face of the housing and engaging the corresponding conductive pad;
• wherein
• the extending beam provides most of resiliency of the contact when the contact abuts against the corresponding downwardly pressing conductive pad, and the at least on portion of the contact region is intentionally oblique to the extending beam, from the top view, to direct to the corresponding conductive pad for maximizing the superposing areas therebetween.

An electrical connector assembly comprising:

• an electronic package with a plurality of conductive pads on an underside thereof;
• an insulative housing defining a plurality of passageways therein;
• a plurality of contacts disposed in the corresponding passageways, respectively, each of said contacts including:
• a base portion;
• a soldering portion located below the base portion for mounting to a printed circuit board;
• an arm defining thereof a lower portion integrally extending from the base portion, and an upper portion opposite to said lower portion, said upper portion essentially extending in an upward oblique direction from a side view, said upper portion including:
• an extending beam defining a first axis along a first lengthwise direction thereof from a top view;
• a connecting beam extending from an upper end of the extending beam and defining a second axis along a second lengthwise direction thereof from the top view, said first direction and said second direction defining an acute angle therebetween;
• a contacting portion extending from an upper end of the connecting beam for engagement with the corresponding pad;
• wherein
• the contacting portion is essentially laterally offset from a centerline of the extending beam from the top view.
