Abstract
A chip carrier socket (10) for use with the LGA chip (110), includes a base (12) having an internal cavity (15) for receiving therein a cover (14) hinged to the base (12) whereby the LGA chip (110) may be sandwiched between the cover (14) and the base (12). A plurality of passageways (22) are formed in the base (12) in a vertical direction for receiving a corresponding number of contacts (100) therein. The cover (14) is moved with regard to the base (12) in both vertical and horizontal directions so that when the socket (10) is in a closed state, the contacts (100) of the socket (10) may abut against the corresponding landing plates (112) disposed on the undersurface of the LGA chip (110) for interconnection.
Claims19
A chip carrier socket for receiving a chip carrier therein comprising:
- a base having bottom plate with a plurality of passageways extending therethrough for receiving a corresponding number of contacts therein;
- two side walls disposed on two sides of the bottom plate, and a nest section disposed on a rear portion, said side walls and nest section commonly defining a cavity therein;
- a cover including a pressing portion adapted to be received within said cavity, and a hinge portion coaxial fastened to said nest section of the base;
- and
- means for guiding the cover to move with regard to the base in both vertical and horizontal directions under a condition that said cover always maintains in a horizontal state during movement of the cover.
A contact for use within a passageway of a chip carrier socket comprising:
- a plate type main body;
- a tail downward extending from the main body;
- a resilient section upward extending from the main body wherein an imaginary plane constructed by said resilient section;
- a contact section integrally and laterally extending from a distal end of the resilient section in a direction which is different from the elastic direction of said resilient section.
A chip carrier socket for use with a chip carrier, comprising:
- a base having a bottom plate with a plurality of contacts therein;
- a cover fastened to said base and adapted to be relatively moved with regard to the base through an operation of a lever;
- wherein said socket includes means having at least an engaging block and a channel whereby the cover can be up and down moved with regard to the base in back-and-forth direction and under a condition that said cover always keeps in a parallel relation with the base.
A arrangement for loading a chip carrier into a chip carrier socket, said socket comprising:
- a base including a bottom plate having a plurality of contacts therein;
- a cover attached to said base but always keeping in a parallel relation with regard to the base in up and down movement to expose a wider opening allowing a chip carrier to be inserted into said socket in a horizontal direction which is parallel to said base.
A socket for use with a chip carrier comprising:
- a base including a bottom plate having a plurality of contacts therein;
- a cover attached to said base but still back and forth moveable with regard to the base;
- and
- said cover further including restraining means that carries the chip carrier to move in compliance with back-and-forth movement of said cover.
A socket for use with a chip carrier, comprising:
- a base including a bottom plate with a plurality of contacts therein;
- a cover attached to said base but still moveable with regard to the base;
- and
- a set of guidance means including at least a channel and a corresponding engaging block that are respectively disposed on said base and said cover and cooperate with each other wherein said channel further includes at least a upward facing slope surface and a downward facing slope surface to respectively engage with said engaging block of the cover for guiding the rearward/upward and forward/downward movements of the cover with regard to the base.
A socket for use with an electrical component, comprising:
- a base having a plurality of contacts therein;
- a cover attached to said base for cooperating with said base;
- and
- a lever mean actuating the cover to move with regard to the base in a parallel relation and to define a space between said cover and base for receiving said electrical component;
- each of said contacts having contact apex protruding out of the base and into said space to engage with a corresponding electrode disposed on a undersurface of said component that is pressed by the actuated cover.
An arrangement for engagement between an electrode of an electrical component and a contact of an electrical connector wherein said electrode is moved toward the contact in both vertical and horizontal directions whereby a horizontal movement of the electrical component provides a wiping action therewith and a vertical movement of said electrical component increasingly presses said electrode against the contact to have said contact deformed in the vertical direction and enhance engagement between the contact and the electrode, and also to have said contact provide an engagement force opposite to a direction of vertical movement of said electrical component.
A method for assembling a chip carrier socket wherein the socket comprises:
- a base having nest section defining holes extending horizontally, and two side walls defining a plurality of channels therein;
- a lever having a camming shaft including camming sections, and
- a cover having a hinge portion including pockets corresponding to the camming sections of the camming shaft of the lever, and a plurality of engaging blocks corresponding to the channels whereby assembling steps comprising:
- inserting the camming shaft of the lever into the holes of the nest section of the base in a horizontal direction;
- loading the cover onto the base wherein the pockets of the cover receive therein the camming sections of the camming shaft of the lever, and the engaging blocks of the cover are received within the corresponding channels in the base.
