초록 ▼

A dynamic mounting system couples a first object to a second object by the attachment of a threaded member to a threaded receiving member on the second object to a predetermined depth to cause a biased compression member to exert a predetermined clamping force holding the first object to the second. The first object may be a heat sink in communication with a heat-generating component such as a processor mounted on the second object such as a circuit board. The predetermined depth is reached by advancing the threaded member until its threads pass beyond threads on the receiving member. The predetermined depth of threaded member biases the compression member to maintain a clamping force between the first and second objects within a desired range of temperature.

대표청구항 ▼

1. A dynamic mounting system for attaching one object to another, comprising: a heat sink and a second object;a rotatable screw, having a head at a top end and a shank having an unthreaded portion extending downward from said head and a threaded portion at a bottom-most end of greater diameter than said unthreaded portion;an internally threaded nut rigidly affixed to said second object;a biasing compression member acting directly between said screw and the heat sink;said screw being received by said nut rotatably advanceable by threaded engagement therewith and advanceable to a pre-determined maximum depth, where the screw threads extend beyond and disengage from the nut threads; andwherein the elements are selected such that a pre-determined clamp load is applied to components located between the heat sink and the second object. 2. The dynamic mounting system of claim 1 wherein said second object is a circuit board. 3. The device of claim 2 wherein a bottom of the nut is flush with a bottom of the circuit board. 4. The device of claim 2 wherein the nut includes a flange containing a portion of the nut threads and including a lower surface which abuts a top surface of the circuit board. 5. The dynamic mounting system of claim 1 wherein said compression biasing member is a coil spring which surrounds the shank of the screw and acts upon the head of the screw. 6. The dynamic mounting system of claim 5 wherein one end of the spring bears directly upon the heat sink. 7. The dynamic mounting system of claim 1 wherein said screw includes a shoulder, adjacent said head and a collar located immediately below said shoulder. 8. The dynamic mounting system of claim 7 wherein the screw is axially captivated directly to the heat sink by deformation of the heat sink by the collar during forcible application of the screw to the heat sink. 9. The device of claim 8 wherein the shoulder has a length at least equal to the compressed length of the compression member. 10. The device of claim 9 wherein the compression member is a coil spring. 11. The device of claim 10 wherein the threads are of lesser diameter than the shoulder. 12. The dynamic mounting system of claim 1 wherein said nut is a through-hole nut. 13. The dynamic mounting system of claim 1 wherein a bottom portion of the nut includes a counter bore of greater diameter than the threads. 14. The dynamic mounting system of claim 1 wherein said screw passes through aligned apertures in said first and second objects.
