Abstract
A self-locking interposer restraint mechanism is disclosed. Rather than using screws to compress springs, clips are pushed down over the posts to compress the springs. Once the clips are pushed down to a level at which the springs are sufficiently compressed, the clips engage stops fabricated into the posts thereby locking the restraint mechanism.
Claims23
A component restraint system that is used to secure an electronic component to a circuit board, comprising:
- a backing plate;
- a post extending from said backing plate, said post having a plurality of stop surfaces;
- a spring radially disposed around said post;
- and
- a clip which, when inserted onto said post, engages the stop surface of said post and compresses said spring,
- wherein said plurality of stop surfaces permits said spring to be variably compressed.
3 more elements
An electronic assembly, comprising:
- a circuit board;
- a backing plate;
- a plurality of springs;
- plurality of posts extending from said backing plate through said circuit board and said springs;
- an electronic component and heat sink sandwiched between said circuit board and said springs;
- and
- a plurality of clips, one clip per post;
- wherein each clip engages one of the posts in one of a plurality of different positions to compress one of said springs to one of a plurality of different compressive forces.
5 more elements
A computer system, comprising:
- a processor and heat sink;
- an output device coupled to said processor;
- a circuit board;
- a backing plate;
- a plurality of springs;
- a plurality of posts extending from said backing plate through said circuit board and said springs;
- and
- a plurality of clips, one clip per post;
- wherein each of said clips has clip members that are pushed apart to engage the posts in a plurality of different positions to variably compress the springs.
6 more elements
A method comprising:
- compressing, substantially simultaneously, a plurality of springs that bias an electronic component into an interposer socket;
- and
- locking, substantially simultaneously, a plurality of clips on a plurality of posts telescoped one each within the plurality of springs, the plurality of clips hold the plurality of springs in compression.
A system comprising:
- a backing plate defining a plane, the backing plate having a plurality of posts extending substantially perpendicular from the backing plate and each post having a stop surface;
- a circuit board having a plurality of apertures through which the plurality of posts extend;
- an interposer socket on the circuit board within the apertures.
- a plurality of springs radially disposed around each of the plurality of posts;
- a electronic component in operational relationship to the interposer socket and biased toward the interposer socket by the springs;
- an assembly plate holding a plurality of clips;
- wherein each of the plurality of clips are inserted one each onto the plurality of posts by placing the assembly plate over the plurality of posts and compressing the springs;
- and
- wherein the plurality of clips lock one each into the stop surfaces of the posts, holding the springs in compression.
