  • IC socket with two point-contacts
    Patent number: 6540537
    Abstract: The present invention provides an IC socket with two point-contacts which restricts the tracks of contacts contacting with a lead terminal of an IC package. The IC socket with two point-contacts has a pair of contact portions that move forward and backward in response to the vertical movement of a cover. When the pair of contact portions move forward, a lead terminal of an IC package is sandwiched between the pair of contact portions, which have their movement restricted by a contact track cam and contact with the lead terminal under uniform contact force without abutting against an end of the lead terminal or deforming the lead terminal.
