Abstract
Abstract The disclosure features lead frames, molded lead frames and adapters and sockets produced by molding these lead frames. In general, the lead frames comprise a frame and a circuit, wherein the circuit comprises a plurality of electrical conducting elements. The elements are held in position by the frame, and each element comprises an area within the element suitable for positioning a pin through the element to electrically connect the element with the board. The lead frame can be molded in plastic and trimmed to remove the frame to leave each element electrically separate from each other element.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
176 words
An intercoupling component for connection of an integrated circuit package to a circuit board, the package being of the type having a plurality of leads which are placed on said intercoupling component, said intercoupling component comprising a plurality of pins for connection to the circuit board, a plurality of lead frame elements, each said lead frame element being cut from the same lead frame and position relative to other said lead frame elements in the same general orientation as in the lead frame prior to being cut, each said pin being individually secured to a said lead frame element and each said lead frame element including a connection region sized and positioned for making a connection to one of the plurality of leads of the integrated circuit package, and insulative plastic molded around said pins and said lead frame elements to form a molded plastic body, the molded plastic body having a shape providing a plurality of grooves that are adapted to serve in aligning the leads of the integrated circuit package with said connection regions.
Claim 2
Dependent Claim
176 words
An intercoupling component for connection of an integrated circuit package to a circuit board, the package being of the type having a plurality of leads which are placed on said intercoupling component, said intercoupling component comprising a plurality of pins for connection to the circuit board, a plurality of lead frame elements, each said lead frame element being cut from the same lead frame and position relative to other said lead frame elements in the same general orientation as in the lead frame prior to being cut, each said pin being individually secured to a said lead frame element and each said lead frame element including a connection region sized and positioned for making a connection to one of the plurality of leads of the integrated circuit package, and insulative plastic molded around said pins and said lead frame elements to form a molded plastic body, the molded plastic body having a shape providing a plurality of grooves that are adapted to serve in aligning the leads of the integrated circuit package with said connection regions.
Claim 3
Dependent Claim
37 words
The adapter of claim 1 wherein said grooves are separated by walls sized and configured to accept J-leads of a J-Lead package to prevent the J-leads from coming into contact with more than one lead frame element.
Claim 4
Dependent Claim
39 words
