Abstract
Abstract A printed circuit board component mounting support and spacer having a base 20 with a square face 42, 44, 46, 48 and at least four rectangular feet 32, 34, 36, 38 extending out from the square planar surface of base 20. Extending upwards from base 20 are four projections 10, 12, 14, 16 to cradle an electrical component 8. The base 20 has a hole 60 through which the component leads are inserted before inserting the component leads through the appropriate holes in the board. Between each pair of fingers 10, 12 and 14, 16 adjacent the extremities of hole 60 are upwardly projecting nibs 52, 54, 56, 58 to contact the bottom of the component to provide a cooling space and pivot point for minimal transverse movement.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
123 words
A printed circuit board component mounting support and spacer having a base 20 with a square face 42, 44, 46, 48 and at least four essentially rectangular feet 32, 34, 36, 38 extending out from said base 20 characterized in that extending upwards from said base 20 are four projecting fingers 10, 12, 14, 16 to cradle an electrical component 8, between each pair of said upwardly extended fingers 10, 12, 14, 16 are upwardly projecting nibs or projections 52, 54, 56, 58 to contact the bottom of a component 8, and wherein said base 20 has a hole 60 through which the electrical leads of a component 8 are inserted before inserting the component leads through the appropriate holes in the board.
Claim 2
Dependent Claim
123 words
A printed circuit board component mounting support and spacer having a base 20 with a square face 42, 44, 46, 48 and at least four essentially rectangular feet 32, 34, 36, 38 extending out from said base 20 characterized in that extending upwards from said base 20 are four projecting fingers 10, 12, 14, 16 to cradle an electrical component 8, between each pair of said upwardly extended fingers 10, 12, 14, 16 are upwardly projecting nibs or projections 52, 54, 56, 58 to contact the bottom of a component 8, and wherein said base 20 has a hole 60 through which the electrical leads of a component 8 are inserted before inserting the component leads through the appropriate holes in the board.
Claim 3
Dependent Claim
39 words
A component mounting support and spacer as set forth in claim 1 in which said hole 60 is of a cross configuration with the extremities of said hole 60 being adjacent to nibs or projections 52, 54, 56, 58.
Claim 4
Dependent Claim
35 words
A component mounting support and spacer as set forth in claim 2 in which the upwardly projecting fingers 10, 12, 14, 16 are about five times the length of the feet 32, 34, 36, 38.
Claim 5
Dependent Claim
50 words
A component mounting support and spacer as set forth in claim 3 in which the plane of the feet 32, 34, 36, 38, the plane of the base 42, 44, 46, 48, and the plane 22, 24, 26, 28 of fingers 10, 12, 14, 16 are parallel to each other.
Claim 6
Dependent Claim
124 words
A printed circuit board component mounting support and spacer having a base 20 with a square face 42, 44, 46, 48 and at least four essentially rectangular feet 32, 34, 36, 38 extending out from said base 20 characterized in that extending upwards from said base 20 are four projecting fingers 10, 12, 14, 16 to cradle an electrical component 8, between at least two opposite pairs of said upwardly extending fingers 10, 12, 14, 16 are upwardly projecting nibs or projections 52, 54 to contact the bottom of a component 8, and wherein said base 20 has a hole 60 through which the electrical leads of a component 8 are inserted before inserting the component leads through the appropriate holes in the board.
Claim 7
Dependent Claim
124 words
A printed circuit board component mounting support and spacer having a base 20 with a square face 42, 44, 46, 48 and at least four essentially rectangular feet 32, 34, 36, 38 extending out from said base 20 characterized in that extending upwards from said base 20 are four projecting fingers 10, 12, 14, 16 to cradle an electrical component 8, between at least two opposite pairs of said upwardly extending fingers 10, 12, 14, 16 are upwardly projecting nibs or projections 52, 54 to contact the bottom of a component 8, and wherein said base 20 has a hole 60 through which the electrical leads of a component 8 are inserted before inserting the component leads through the appropriate holes in the board.
