Abstract:
A zero insertion/extraction force integrated circuit socket having a plurality of conductive members comprising:(A) an insulating seat body including: a first face adjacent to a circuit board; a second face in contact with one face of an integrated circuit; multiple insertion holes, one end of each insertion hole communicating with the first face of the seat body; and inlay holes communicating with one end of the insertion hole, an other end of the inlay hole communicating with the second face of the seat body, a distance between each two adjacent insertion holes being defined as an insertion pitch, the plurality of conductive members being cut from a blank and sequentially side by side arranged on the blank, a distance between each two adjacent conductive members being defined as a distribution pitch, the conductive members being respectively inserted in the insertion holes of the seat body for a plurality of pins of the integrated circuit to insert therein; and (B) multiple conductive members cut from said blank and sequentially side by side arranged on the blank, a distance between each two adjacent conductive members being defined as a distribution pitch, the conductive members being respectively inserted in the insertion holes of the seat body for the pins of the integrated circuit to insert therein, each conductive member including: (a) an insertion section inserted in the inlay hole of the seat body and fixed therein; (b) an electrically connecting section extending from one end of the insertion section for electrically connecting with the circuit board; and (c) a clamp section, one end of the clamp section being integrally connected with the insertion section, an other end of the clamp section extending in a direction distal from the electrically connecting section, the other end of the clamp section being resilient and being suspended in the insertion hole for the pin of the integrated circuit to insert therein, said other end being movable within said insertion hole the clamp section having: (1) at least two resilient sections, each resilient section having a base end and a resilient end, the base end being integrally connected with the other end of the insertion section and longitudinally extending, the resilient sections being bent corresponding to each other; (2) two contact sections; and (3) first and second guide sections, one of the contact sections and a corresponding one of the guide sections being integrally connected with the resilient ends of the resilient sections, while the other of the contact sections and the corresponding one of the guide sections integrally transversely extending from the one of the contact sections and the guide sections, the resilient sections, contact sections being interlaced and distributed on the blank with the distribution pitch equal to the insertion pitch, whereby the conductive members made from said blank by punching can be fully inserted into the same row of insertion holes of the insulating seat body at one time, each guide section being bent and having a slope, the first and second guide sections being respectively integrally connected with the two opposite contact sections, guiding ends of the first and second guide sections defining a guiding pitch, connecting portions of the guide sections respectively connecting with the contact sections defining a connecting pitch, before the pin of the integrated circuit slides into the space between the two opposite contact sections, a clamping pitch being defined between the contact sections, the clamping pitch and the connecting pitch being both smaller than a width of the pin of the integrated circuit, the guiding pitch of the guiding ends of the guide sections being larger than the width of the pin of the integrated circuit, whereby the pin of the integrated circuit can be easily slid into the space between the guiding ends of the opposite guide sections and guided by the slopes of the guide sections to smoothly slide into the space between the opposite contact sections, the pin of the integrated circuit being then clamped by the opposite contact sections which originally define a pitch smaller than the width of the pin to achieve an excellent contact effect, said first guide section of said conductive member engaging said second guide section of an adjacent conductive member in a mating relationship when said conductive members are being formed from said blank.
