Abstract

An electric contact used to electrically connecting an IC socket to a PCB, comprises an upper contact, a lower contact and an elastic member between them. The upper contact comprises a first connecting portion to be connected to the IC socket and a first contacting portion with less length than the first connecting portion. The lower contact comprises a second connecting portion and a second contacting portion connecting with the second connecting portion. The second connecting portion includes an expanding portion adjacent to the second contacting portion. The second contacting portion forms a receiving space for the first contacting portion. The first connecting portion also defines a protruding portion projecting along a thickness direction.

First claim

What is claimed is:

1. An electrical connector comprising:
a lower contact assembly including an insulative lower holding member, a plurality of lower contacts retaining in the lower holding member in a fixed manner;
an upper contact assembly stacked upon the lower contact assembly in a vertical direction, and including an insulative upper holding member, a plurality of upper contacts retained in the upper holding member in an up-and-down floating manner;
an upper end section of each of said upper contacts extending upwardly above an upper face of the upper holding member for contacting an electronic package, and a lower end section of each of said upper contacts extending downwardly beyond a bottom face of the upper holding member and through an upper face of the lower holding member and further into the lower holding member to mechanically and electrically connect to the corresponding lower contact; and
a lower end of each of said lower contacts extending downwardly beyond a bottom face of the lower holding member for connecting to a printed circuit board; wherein
each of said upper contacts is equipped with a spring with thereof a lower end that abuts downwardly against a lower portion of the upper holding member and an upper end upwardly abuts an upper portion of the upper contact to urge the upper contact upwardly; wherein
said upper holding member includes a first holding member and second holding member opposite to each other to commonly sandwich the upper contacts and the associated springs therebetween in the vertical direction; wherein
the first holding member and the second holding member are essentially same with each other.

2. An electrical connector comprising:
a lower contact assembly including an insulative lower holding member, a plurality of lower contacts retaining in the lower holding member in a fixed manner;
an upper contact assembly stacked upon the lower contact assembly in a vertical direction, and including an insulative upper holding member, a plurality of upper contacts retained in the upper holding member in an up-and-down floating manner;
an upper end section of each of said upper contacts extending upwardly above an upper face of the upper holding member for contacting an electronic package, and a lower end section of each of said upper contacts extending downwardly beyond a bottom face of the upper holding member and through an upper face of the lower holding member and further into the lower holding member to mechanically and electrically connect to the corresponding lower contact; and
a lower end of each of said lower contacts extending downwardly beyond a bottom face of the lower holding member for connecting to a printed circuit board; wherein
each of said upper contacts is equipped with a spring with thereof a lower end that abuts downwardly against a lower portion of the upper holding member and an upper end upwardly abuts an upper portion of the upper contact to urge the upper contact upwardly; wherein
the upper holding member and the lower holding member are essentially same with each other.
