Integrated circuit socket
View Patent ↗An integrated circuit socket includes an insulating housing having a plurality of contact openings arranged in rows and a recess that receives an integrated circuit package. A plurality of contacts arranged in a first contact group and a second contact group in the insulating housing. Each of the contacts has a flat plate fixing member fixed in the contact opening, a connecting member extending from a lower portion of the fixing member, and a spring member extending diagonally upward from an upper portion of the fixing member. The spring member has a contact member extending into the recess. The contacts are arranged in the contact openings such that the spring members are arranged at an angle offset from a direction of arrangement of the rows and the spring arms of the first contact group are arranged in a direction opposing the spring arms of the second contact group.
1. An integrated circuit socket, comprising:
an insulating housing having a plurality of contact openings being two-dimensionally arranged laterally and longitudinally in a series of rows and columns and a recess that receives an integrated circuit package, the contact openings each having a side wall;
a plurality of contacts arranged in a first contact group along a first of two sides of the insulating housing and a second contact group along a second of the two sides of the insulating housing, each of the contacts having a flat plate fixing member fixed in the contact opening, a connecting member extending from a lower portion of the fixing member, and a spring member extending diagonally upward from an upper portion of the fixing member, the spring member having a contact member extending into the recess;
the contacts being arranged in the contact openings such that the spring members and side walls are arranged at an angle offset from a direction of arrangement of the rows and the spring arms of the first contact group are arranged in a direction opposing the spring arms of the second contact group; and
the plurality of contacts being arranged such that at least one of the side walls faces a contact opening lying in an adjacent column and also lying in a row separated therefrom by another row;
wherein the first contact group diagonally extends in a direction different from that of the second contact group.
2. The integrated circuit socket of claim 1 , wherein the spring arms of the first contact group and the spring arms of the second contact group bend toward each other when contacted by electric contact pads of the integrated circuit package.
3. The integrated circuit socket of claim 1 , wherein each side wall is in surface contact with the fixing member to define the angle of orientation of the spring arms.
4. The integrated circuit socket of claim 1 , wherein a plate shaped second spring member extends between the fixing member and the connection member.
5. The integrated circuit socket of claim 1 , wherein the contact member is substantially U-shaped.
