Abstract
Abstract A load spring for heat sink assemblies has elongated body with a plurality of fingers and a wedge member positioning the spring with respect to a wall of a heat sink housing. The fingers apply a force onto the electrical components to clamp the electrical components against the heat sink housing to provide heat dissipation from the electrical components to the housing.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
103 words
A load spring assembly for a heat sink assembly including a heat sink housing comprising: an elongated body member; one or more biasing members extending from said body member, said one or more biasing members adapted for contacting electrical components to be secured in the heat sink assembly; and wedge means adapted for securing the load spring assembly to the heat sink housing, said wedge means being adapted to be received within an aperture formed in the load spring assembly and to abut a portion of the heat sink housing to position the load spring assembly with respect to the heat sink housing.
Claim 2
Dependent Claim
103 words
A load spring assembly for a heat sink assembly including a heat sink housing comprising: an elongated body member; one or more biasing members extending from said body member, said one or more biasing members adapted for contacting electrical components to be secured in the heat sink assembly; and wedge means adapted for securing the load spring assembly to the heat sink housing, said wedge means being adapted to be received within an aperture formed in the load spring assembly and to abut a portion of the heat sink housing to position the load spring assembly with respect to the heat sink housing.
Claim 3
Dependent Claim
23 words
The load spring according to claim 1 wherein said one or more biasing members each include a portion for contacting the electrical components.
Claim 4
Dependent Claim
41 words
The load spring assembly according to claim 1 wherein said wedge means adapted for contacting a wall of the heat sink housing to position the load spring on the heat sink housing and provide a retaining force in said biasing members.
Claim 5
Dependent Claim
112 words
A load spring assembly for a heat sink assembly including a heat sink housing comprising: an elongated body member having one or more apertures; a plurality of fingers extending from said body members, said plurality of fingers including a portion adapted for contacting electrical components to maintain the electrical components abutted against the heat sink housing; and one or more wedge members, said one or more wedge members adapted to move through said one or more apertures to engage a wall of the heat sink housing for positioning the load spring with respect to the heat sink housing and to load said fingers to apply a clamping force on the electrical components.
Claim 6
Dependent Claim
112 words
A load spring assembly for a heat sink assembly including a heat sink housing comprising: an elongated body member having one or more apertures; a plurality of fingers extending from said body members, said plurality of fingers including a portion adapted for contacting electrical components to maintain the electrical components abutted against the heat sink housing; and one or more wedge members, said one or more wedge members adapted to move through said one or more apertures to engage a wall of the heat sink housing for positioning the load spring with respect to the heat sink housing and to load said fingers to apply a clamping force on the electrical components.
Claim 7
Dependent Claim
25 words
The load spring assembly according to claim 4 wherein said plurality of fingers each have a free extending end adapted to contact a carrier member.
Claim 8
Dependent Claim
43 words
The load spring assembly according to claim 4 wherein one or more members extend from an opposing side of said plurality of fingers on said body member, said one or more members providing a contact surface for said one or more wedge members.
Claim 9
Dependent Claim
119 words
A load spring assembly for a heat sink assembly including a heat sink housing comprising: an elongated body member having a first and second edge portion; a plurality of fingers extending from said first edge portion of said body member and at least one arm member extending from the second edge portion, said fingers having a portion extending inward adapted for contacting electrical components for maintaining the electrical components in contact with the heat sink housing; and one or more wedge members for retaining said load spring assembly in position on the heat sink housing, said one or more wedge members adapted to abut between a wall of the heat sink housing and said at least one arm member.
Claim 10
Dependent Claim
119 words
A load spring assembly for a heat sink assembly including a heat sink housing comprising: an elongated body member having a first and second edge portion; a plurality of fingers extending from said first edge portion of said body member and at least one arm member extending from the second edge portion, said fingers having a portion extending inward adapted for contacting electrical components for maintaining the electrical components in contact with the heat sink housing; and one or more wedge members for retaining said load spring assembly in position on the heat sink housing, said one or more wedge members adapted to abut between a wall of the heat sink housing and said at least one arm member.
Claim 11
Dependent Claim
21 words
