Chip carrier socket

Claim 2

In a socket for carrying an integrated circuit chip, said socket including a base member having an integral table means for supporting said chip, a plurality of resilient electrically conductive contact means anchored in said base member, said contact means constituting means for engaging leads connected to said chip to secure the chip within said socket, said contact means positioned along two opposite sides of said base member, and a top means for urging said contact means between a flexed latched position engaging said chip leads, and an unlatched position spaced from said chip wherein the chip may be removed from the socket, the improvement wherein said top means includes peripheral sidewalls defining a central opening therethrough for inserting said chip therein, each contact means including an elongated longitudinal stem extending upwardly from said base member into said central opening, each contact means including an upper transverse beam part having an outer edge in abutment with an upwardly tapered portion of one of said peripheral side walls of said top, biasing means operatively associated with said base member and top means for normally urging the top means away from said base member wherein each contact means is urged into said latched position, said beam part having an inner edge positioned adjacent to said table and contacting a lead of said chip when the contact means are in the latched position.

Claim 3

The socket of claim 1 wherein said peripheral side walls define an inset lower shoulder part, said beam part outer edge contacting said shoulder part when the contacts are in the latched position to halt upward movement of the top means.

Claim 4

The socket of claim 1 wherein said peripheral side walls define a downwardly tapered surface having an inwardly angled upper ledge defining a first angle with said side wall, and a lower ledge defining a second angle with respect to the side wall of a greater degree than said first angle.

Claim 5

A socket for carrying and supporting an integrated circuit chip, said socket comprising: a) a base member including central upper table means for supporting said chip; b) a plurality of electrically conductive contacts anchored to said base member, each contact including an elongated longitudinal stem and an upper beam extending transversely of said stem; c) a top having a continuous peripheral side wall defining a central opening for inserting said chip therein, said table means positioned in said central opening; d) said peripheral side wall having a downwardly tapered portion, said upper beam having an outer edge abutting against said downwardly tapered portion wherein upward movement of said top relative to said base flexes said contacts into a latched position with said contacts contacting leads of said chip, and downward movement of said top allows said contacts to flex into an unlatched position with the contacts spaced from said leads; and e) biasing means operatively associated with said top and base member for urging said top upwardly away from said base member wherein the contacts are normally in said latched position.

Claim 6

A socket for carrying and supporting an integrated circuit chip, said socket comprising: a) a base member including central upper table means for supporting said chip; b) a plurality of electrically conductive contacts anchored to said base member, each contact including an elongated longitudinal stem and an upper beam extending transversely of said stem; c) a top having a continuous peripheral side wall defining a central opening for inserting said chip therein, said table means positioned in said central opening; d) said peripheral side wall having a downwardly tapered portion, said upper beam having an outer edge abutting against said downwardly tapered portion wherein upward movement of said top relative to said base flexes said contacts into a latched position with said contacts contacting leads of said chip, and downward movement of said top allows said contacts to flex into an unlatched position with the contacts spaced from said leads; and e) biasing means operatively associated with said top and base member for urging said top upwardly away from said base member wherein the contacts are normally in said latched position.

Claim 7

The socket of claim 4 wherein each contact includes an uppermost second beam extending transversely of said stem, said uppermost beam spaced upwardly from said upper beam and having an inward edge contacting said chip lead when the contacts are in their said latched position.

Claim 8

The socket of claim 5 wherein said peripheral side wall includes an inset lower shoulder part, said upper beam having a first edge contacting said shoulder part when the contacts are in said latched position to halt upward movement of the top.

Claim 9

The socket of claim 5 wherein said uppermost beam has an outward edge spaced from said inner side wall.

Claim 10

In a socket for carrying an integrated circuit chip, said socket including a base member having an integral table means for supporting said chip, a plurality of resilient electrically conductive contact means anchored in said base member, said contact means constituting means for engaging leads connected to said chip to secure the chip within said socket, said contact means positioned along two opposite sides of said base member, and a top means for urging said contact means between a flexed latched position engaging said chip leads, and an unlatched position spaced from said chip wherein the chip may be removed from the socket, the improvement wherein said top means includes peripheral side walls defining a central opening therethrough for inserting said chip therein, each contact means including an elongated stem extending upwardly from said base member into said central opening, each contact means including an upper beam part having a first edge in abutment with an upwardly tapered portion of one of said peripheral side walls of said top, biasing means operatively associated with said base member and top means for normally holding the top means spaced upwardly from said base member when each contact means is in the latched position, said beam part having a second edge positioned adjacent to said table and contacting a lead of said chip when the contact means are in the latched position, one of said peripheral side walls defining an inset lower shoulder part, said beam part first edge contacting said lower shoulder part when the contacts are in the latched position to halt upward movement of said top means.

Claim 11

In a socket for carrying an integrated circuit chip, said socket including a base member having an integral table means for supporting said chip, a plurality of resilient electrically conductive contact means anchored in said base member, said contact means constituting means for engaging leads connected to said chip to secure the chip within said socket, said contact means positioned along two opposite sides of said base member, and a top means for urging said contact means between a flexed latched position engaging said chip leads, and an unlatched position spaced from said chip wherein the chip may be removed from the socket, the improvement wherein said top means includes peripheral side walls defining a central opening therethrough for inserting said chip therein, each contact means including an elongated stem extending upwardly from said base member into said central opening, each contact means including an upper beam part having a first edge in abutment with an upwardly tapered portion of one of said peripheral side walls of said top, biasing means operatively associated with said base member and top means for normally holding the top means spaced upwardly from said base member when each contact means is in the latched position, said beam part having a second edge positioned adjacent to said table and contacting a lead of said chip when the contact means are in the latched position, one of said peripheral side walls defining an inset lower shoulder part, said beam part first edge contacting said lower shoulder part when the contacts are in the latched position to halt upward movement of said top means.
