Socket with oppositely arrayed terminals
First Claim
1. A socket adapted for electrically connecting a semiconductor package to a printed circuit board, comprising:
- an insulating body having a mating face, a mounting face opposite to the mating and a plurality of passageways passing through the mating face and the mounting face, the insulating body formed with two areas separated by a beeline, the passageways distributed on both of the two areas, the insulating body defining two position holes on two diagonal corners thereof; and
a plurality of terminals received in the passageways and each having an elastic arm protruding out of the mating face of the insulating body, extending directions of the elastic arms of the terminals in same area being uniform and toward the corresponding position hole, and being opposite with that of the elastic arms of the terminals in the other area, and the extending directions of all the elastic arms of the terminals being parallel to the beeline.

Abstract
A socket (100) adapted for electrically connecting a semiconductor package (200) and a PCB (300), comprises an insulating body (10) and a plurality of terminals (20) each having an elastic arm. The insulating body has a mating face (101), a mounting face (102) opposite to the mating face and a plurality of passageways (103) passing through the mating face and the mounting face. The insulating body is formed with a first and a second areas (1011, 1012) separated by a beeline (L1), the passageways are distributed on both of the areas. The terminals are received in the passageways, and extending directions of the terminals in a same area are uniform but opposite with that of the terminals in the other area. And the extending directions of all the terminals are parallel to the beeline.

15. A socket for use with an electronic package comprising:
-
an insulative body being of a rectangular contour having first and second lengthwise edges and first and second transverse edges alternately perpendicular with one another in sequence along lengthwise and transverse directions, respectively; first and second position holes formed around opposite first and second corners of the body and defining therebetween a line around at a forty-five degrees with regard to said four edges; a plurality of passageways formed in the body and arranged essentially in an N×
N manner except that two of said passageways around said opposite first and second corners are replaced by said pair of position holes,each of said passageways defining a rectangular configuration having a long side and a short side in a top view to receive a corresponding contact having an elastic arm extending along said long side and parallel to the lengthwise direction, the passageways being divided into first and second groups via a beeline which extends along the lengthwise direction wherein the first position hole belongs to the first group and the second position hole belongs to the second group, the elastic arms in the corresponding passageways of said first group directing toward the second transverse edge and those in the corresponding passageways of the second group directing toward the first transverse edge under condition of having the first position hole and the corresponding elastic arm in the neighboring passageway in a same lengthwise row not to interfere with each other in said top view, and having the second position hole and the corresponding elastic arm in the neighboring passageway in another same lengthwise row not to interfere with each other in said top view; the passageways in an outermost transverse row of said first group and being far away from the first position hole, being closer to the first transverse edge than those in another outermost transverse row of the second group and essentially aligned with the second hole, the passageways in an outermost transverse row of said second group and being far away from the second position hole, being closer to the second transverse edge than those in another outermost transverse row of the first group and essentially aligned with the first position hole;
whereinthe passageways in the first group and those in the second group are essentially offset away from each other in the lengthwise direction so as to form a first unused area in the first group closer to the second transverse edge and a second unused area in the second group closer to the first transverse edge, thus resulting in an asymmetric arrangement of all said passageways of said first group and said second group in the lengthwise direction.
