Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
135 words
A heat sink assembly for mounting an electronic component comprising: a heat sink body, having a planar component mounting surface, and having a rail mounting groove, and having a component, clip mounting channel proximate said planar component mounting surface; a mounting rail positioned within said rail mounting groove, said mounting rail defining a mounting axis; a component clip having a spring arm and having an anchor arm, said anchor arm position in said component clip mounting channel, said spring arm coupled to said anchor arm by a bend; whereby a component placed under said spring arm deflects said bend into contact with a portion of said clip mounting channel causing said bend to act a fulcrum and thereby elastically deflecting said component clip producing a clamping force to hold the component against said planar surface.
Claim 2
Dependent Claim
135 words
A heat sink assembly for mounting an electronic component comprising: a heat sink body, having a planar component mounting surface, and having a rail mounting groove, and having a component, clip mounting channel proximate said planar component mounting surface; a mounting rail positioned within said rail mounting groove, said mounting rail defining a mounting axis; a component clip having a spring arm and having an anchor arm, said anchor arm position in said component clip mounting channel, said spring arm coupled to said anchor arm by a bend; whereby a component placed under said spring arm deflects said bend into contact with a portion of said clip mounting channel causing said bend to act a fulcrum and thereby elastically deflecting said component clip producing a clamping force to hold the component against said planar surface.
Claim 3
Dependent Claim
17 words
The heat sink assembly of claim 1 wherein planar surface does not intersect with said mounting axis.
Claim 4
Dependent Claim
21 words
The heat sink assembly of claim 1 wherein said component clip further comprises a thrust surface for contacting the electronic component.
Claim 5
Dependent Claim
46 words
The heat sink assembly of claim 1 wherein said component clip further comprises a thrust surface for contacting the electronic component, includes a crease for abutting the electronic component, whereby said clamping force is essentially independent of the portion of said crease on the electronic component.
Claim 6
Dependent Claim
25 words
The heat sink assembly of claim 1 wherein said anchor arm further comprise an anchor bend formed at the terminal end of said anchor arm.
Claim 7
Dependent Claim
25 words
The heat sink assembly of claim 2 wherein said anchor arm further comprises an anchor bend formed at the terminal end of said anchor arm.
Claim 8
Dependent Claim
46 words
The heat sink assembly of claim 6 wherein said component clap mounting channel includes a ridge parallel to said mounting axis and contacting a portion of said anchor bend; whereby said anchor bend is elastically deformed by placement of the electronic component under said component clip.
Claim 9
Dependent Claim
174 words
A heat sink assembly for mounting an electronic component comprising: a heat sink body, having a planar component mounting surface, and having a rail mounting groove, and having a component clip mounting channel proximate said planar component mounting surface; a mounting rail positioned within said rail mounting groove, said mounting rail defining a mounting axis; a component clip having a spring arm and having an anchor arm, said anchor arm positioned in said component clip mounting channel; said anchor arm further comprise an anchor bend formed at the terminal end of said anchor arm, said spring arm coupled to said anchor arm by a bend; said component clip mounting channel including a ridge parallel to said mounting axis contacting a portion of said anchor bend; whereby an electronic component placed under said spring arm deflects said bend into contact with a portion of said clap mounting channel causing said bend to act a fulcrum and thereby elastically deflecting said component clip producing a clamping force to hold the electronic component against said planar surface.
Claim 10
Dependent Claim
174 words
A heat sink assembly for mounting an electronic component comprising: a heat sink body, having a planar component mounting surface, and having a rail mounting groove, and having a component clip mounting channel proximate said planar component mounting surface; a mounting rail positioned within said rail mounting groove, said mounting rail defining a mounting axis; a component clip having a spring arm and having an anchor arm, said anchor arm positioned in said component clip mounting channel; said anchor arm further comprise an anchor bend formed at the terminal end of said anchor arm, said spring arm coupled to said anchor arm by a bend; said component clip mounting channel including a ridge parallel to said mounting axis contacting a portion of said anchor bend; whereby an electronic component placed under said spring arm deflects said bend into contact with a portion of said clap mounting channel causing said bend to act a fulcrum and thereby elastically deflecting said component clip producing a clamping force to hold the electronic component against said planar surface.
