Prefabricated rubber socket
View Patent ↗The present disclosure relates to a rubber socket formed by assembling a plurality of individually manufactured electrically-conductive blocks, the blocks having a plurality of elastic electrically-conductive parts and an insulating part, respectively, are individually manufactured, a lower protruding portion, having a thickness smaller than that of the support member, of each electrically-conductive part is inserted into the through hole of the support member, the electrically-conductive block is coupled to the support member by adhering a lower surface of the insulating part to an upper surface of the support member to enable a large-area rubber socket to be manufactured.
1 . A rubber socket disposed between a device under test and a tester to electrically connect terminals of the device under test and pads of the tester to each other, comprising:
a plate-shaped support member comprising a central region portion having through holes formed therein and at positions corresponding to the terminals of the device under test, respectively and having a plurality of divided zones, and a peripheral region portion located outside the central region portion; and
a plurality of electrically-conductive blocks, each block disposed in one of the divided zones of the support member and each block having a size corresponding to a size of one of the divided zones, respectively, the electrically-conductive blocks being individually manufactured prior to being disposed on the support member and independently separated from each other such that insulating parts of adjacent electrically-conductive blocks are not connected to each other, each electrically-conductive block being provided with electrically-conductive parts formed by arranging a plurality of electrically-conductive particles in an elastic insulating material in a thickness direction and an insulating part disposed around the electrically-conductive parts to insulate and support the electrically-conductive parts,
wherein the electrically-conductive parts are formed at positions corresponding to the through holes of the divided zones, respectively, each electrically-conductive part has a lower protruding portion protruding below the insulating part, having a thickness greater than that of the support member and inserted into the through hole, and a lower surface of the insulating part is adhered to an upper surface of the support member by an adhesive applied the upper surface of the support member, so the electrically-conductive block is coupled to the support member.
2 . The prefabricated rubber socket of claim 1 , wherein the plurality of divided zones has the same size.
3 . The prefabricated rubber socket of claim 1 , wherein the electrically-conductive part has an upper protruding portion protruding above the insulating part.
4 . The prefabricated rubber socket of claim 3 , wherein a support film is attached to an upper surface of the insulating part.
5 . The prefabricated rubber socket of claim 1 , wherein the adhesive is silicon adhesive.
6 . The prefabricated rubber socket of claim 1 , wherein the support member is made of engineering plastic.
7 . The prefabricated rubber socket of claim 1 , wherein the support member has a plurality of position alignment holes formed in the peripheral region portion thereof for aligning a position thereof.
8 . The prefabricated rubber socket of claim 1 , further comprising a frame to which the peripheral region portion of the support member is attached, the frame comprising a plurality of position alignment holes formed therein for aligning a position thereof.
9 . The prefabricated rubber socket of claim 1 ,
wherein the plurality of electrically-conductive blocks comprises blocks each having electrically-conductive parts of the same height,
wherein at least one of the blocks of the socket has electrically-conductive parts of a height different from that of another block of the socket.
