1. A land grid array socket, comprising:
- a dielectric housing defining a plurality of passages extending between an upper surface and a lower surface thereof; and
a plurality of conductive terminals disposed in corresponding passages, respectively, each terminal comprising a base portion secured in the passage and a flexible arm integrally formed with the base portion, the flexible arm successively protruding beyond the upper surface and the lower surface of the housing to form an upper contacting portion and a lower contacting portion, the upper contacting portion having multiple contacting areas to ensure reliable electrical connection between the terminal and an electronic component seated thereon.

Abstract
A land grid array socket (10) includes a dielectric housing (20) defining a number of passages (204) between an upper surface (202) and a lower surface (206) thereof and a number of terminals (30) residing in corresponding passages, respectively. Each terminal includes a base portion (300) secured in the passage and a flexible arm (302) successively sticking out of the upper surface and the lower surface of the housing to define an upper contacting portion (3022) and a lower contacting portion (3026). The upper contacting portion defines multiple contacting areas, so as to establish reliable electrical connection between the terminal and a land grid array package (40) seated thereon.

8. A conductive terminal, comprising:
-
a base portion; and
a resilient arm integrally formed with the base portion, the resilient arm having an upper beam projecting upwardly away from the base portion and a lower beam extending downwardly toward the base portion from a distal end of the upper beam, the resilient arm defining an upper contacting portion at a junction of the upper beam and the lower beam and a lower contacting portion at a distal end of the lower beam, the upper contacting portion defining multiple discrete contacting areas to form reliable electrical engagement with an electronic component placed thereon. - View Dependent Claims (9, 10, 11, 12, 13)

14. An electrical connector comprising:
-
an insulative housing defining a plurality of passageways extending therethrough vertically, each of said passageways including a small retention recess and a large body opening;
a plurality of contacts respectively disposed in the corresponding passageways, each of the contacts including;
a base section received in the corresponding retention recess, a resilient arm extending from the base section and defining upper and lower contact regions, along a longitudinal direction of said resilient arm, exposed to an upper face and a lower face of the housing;
whereinat least one of said upper and lower contact regions is divided into two areas spaced from each other in a transverse direction perpendicular to said longitudinal direction. - View Dependent Claims (15)
