Abstract
A clip secures a heat sink having a slot with grooves on opposing sides thereof to a transistor. The frame has sides with a width therebetween which can be wedged into grooves on opposing sides of a slot in the heat sink. A portion of the frame is raised up between two parallel cuts in the frame. A transistor is wedged under the raised up portion. The clip has legs which are insertable into a printed circuit board for easy assembly of a heat sink, transistor, clip and printed circuit board.
Claims20
A clip for securing a heat sink to an electronic device, said heat sink having upstanding parallel fins and two members extending parallel to but in opposite directions from said fins, a bottom extending between said two members, a slot defined by said two members and grooves on opposing sides of said two members at said bottom of said slot, said clip comprising:
- a frame having sides with a width therebetween which can be wedged into said grooves of said heat sink;
- a barb extending outwardly from said frame, said barb bearing against said heat sink to secure said frame to said heat sink;
- and
- means for securing said electronic device to said frame so that said device is held directly against said heat sink.
The combination of a heat sink and a clip for securing an electronic device to said heat sink, said heat sink comprising:
- upstanding parallel fins extending from said heat sink;
- and
- a slot on said heat sink defined by two members extending parallel to but in opposite directions from said fins and a bottom extending between said two members, said slot having grooves on opposing sides of said members at the bottom of said slot, said clip comprising:
- a frame having sides with a width therebetween wedged into said grooves of said heat sink;
- and
- means for securing said electronic device to said frame so that said device is held directly against said heat sink.
A clip for securing a heat sink to an electronic device, said heat sink having upstanding parallel fins and two members extending parallel to but in opposite directions from said fins, a bottom extending between said two members, a slot defined by said two members and grooves on opposing sides of said two members at said bottom of said slot, said clip comprising:
- a frame having sides with a width therebetween which can be wedged into said grooves of said heat sink;
- and
- means for securing said electronic device to said frame including a single raised up portion defined by two parallel cuts in said frame, said parallel cuts being spaced apart by the width of said electronic device so that the sides of said frame outside of said raised-up portion are guide rails for insertion of said device under said raised-up portion so that said electronic device can be secured directly against said heat sink by said raised up portion.
A clip for securing a heat sink to an electronic device, said heat sink having upstanding parallel fins and two members extending parallel to but in opposite directions from said fins, a bottom extending between said two members, a slot defined by said two members and grooves on opposing sides of said two members at said bottom of said slot, said clip comprising:
- a frame having sides with a width therebetween which can be wedged into said grooves of said heat sink;
- and
- means for securing said electronic device to said frame so that said device is held directly against said heat sink,
- feet extending downwardly from said frame, said feet being insertable into a printed circuit board, said feet being in the surface of said frame, the surface of said frame above said feet being bent over to form a stand-off portion engaging the surface of said printed circuit board to keep the heat sink from contacting said printed circuit board.
