ABSTRACT:
This invention relates to an electrical connector with zero insert force (ZIF) socket. When the sliding support is moved traverse, the pins of the Pin Grid Arrays (PGA) packages can be received and retained by the specially designed terminal connecting end to facilitate an easily mounting and excellent conductivity as well as durability. Characterized in that a pin socket is formed directly from punching a metal sheet. A first supporting arm and a second supporting arm are defined thereof. The first supporting arm has a longer length than the second supporting arm. The first supporting arm and the second supporting arm are further formed a first contacting end and a second contacting end respectively at their upper portion. The first contacting end and the second contacting end are intersected with each other. A first curve portion is formed at the first supporting arm and a second curve portion being formed at the second supporting arm. The first curve portion is larger than the second curve portion. The first contacting end and the second contacting end being separated with each other. A first conductive surface and a second conductive surface are defined at the first contacting end and the second contacting end respectively thereof. The end result is reflected in the reduction in friction resistance and increase in the service life of the device.
