Abstract
A zero insertion force (ZIF) socket for electrically connecting an electronic package and a mother board, comprises an insulative cover, a driving device, an insulative base defining a number of engaging slots therein and at least two types of engaging terminals received in the corresponding engaging slots. The engaging terminals or rows of the engaging slots are each offset relative to each other. Thus, electrical contacts are established between the engaging terminals and conductive terminals of the electronic package at different times thereby effectively lowering the operating resistance of the ZIF socket.
Claims5
A zero insertion force socket for electrically connecting an electronic package with a mother board, said electronic package having a plurality of conductive terminals disposed in rows, the conductive terminals in a same row are not offset relative to each other in a predetermined direction, said socket comprising:
- an insulative base defining a plurality of engaging slots therethrough arranged in an array;
- an insulative cover operably mounted on the insulative base and being slidable along the insulative base in a first sliding direction defined by relative sliding movement between the insulative cover and the insulative base, and defining a plurality of terminal receiving passageways therein adapted for receiving conductive terminals of an electronic package therein;
- and
- a plurality of engaging terminals each being received in a corresponding engaging slot of the insulative base, the engaging terminals comprising at least first engaging terminals and second engaging terminals, each of the first and second engaging terminals having a contact section adapted for contacting a corresponding conductive terminal of the electronic package;
- wherein
- the array of engaging slots in the insulative base comprises at least one row extending in a second direction which is perpendicular to said first sliding direction, and wherein the adjacent engaging slots in said at least one row are not offset relative to each other in said first sliding direction, and wherein the first engaging terminals and the second engaging terminals are alternately disposed in the rows of engaging slots in said second direction, wherein the contact sections of the first and second engaging terminals in said at least one row of engaging slots are offset from each other.
A zero insertion force socket assembly comprising:
- an insulative base defining a plurality of engaging slots therethrough arranged in at least one row;
- a plurality of engaging terminals received within the engaging slots of the base;
- an electronic package including a plurality of conductive terminals engageable with corresponding engaging terminals, said package being relatively moveable with regard to the base along a first sliding direction defined by relative movement between the package and the base;
- the engaging terminals comprising first type engaging terminals and second type engaging terminals alternatively disposed in said at least one row of the slots of the base in a second direction perpendicular to the first sliding direction, wherein said first type engaging terminals and said second type engaging terminals have contact sections which are offset different distances relative to the corresponding conductive terminals of the package along said first sliding direction so that when the conductive terminals relatively move toward and successively contact the respective corresponding engaging terminals, said first type engaging terminals are engaged by the corresponding conductive terminals before the second type engaging terminals are engaged by the corresponding conductive terminals.
