Abstract

A translating hinge includes a translation element which provides translational movement between two objects coupled by the translating hinge and a rotating assembly coupled to the translation element.

Claims

1. A radio frequency (RF) system comprising:

a first heat sink assembly of the RF system having a first surface;

a second heat sink assembly of the RF system having a first surface and disposed over said first heat sink assembly, the first and second heat sink assemblies providing cooling to electronic components;

a translating hinge coupled to said first and second heat sink assemblies, said translating hinge configured to translate in a direction normal to the first surface of a first one of said first and second heat sink assemblies and to rotate the second heat sink assembly away from the first heat sink assembly,

wherein said translating hinge comprises;

a translation element configured to move between a closed position and a translated position with the movement being solely in a substantially vertical direction between the first heat sink assembly and second heat sink assembly by raising the second heat sink assembly with respect to the first heat sink assembly, the vertical direction being perpendicular to mating surfaces of the first and second heat sink assemblies; and

a rotating assembly coupled to said translation element, said rotating assembly configured to allow the second heat sink assembly to be rotated relative to the first heat sink assembly when the translation element is in a translated position.

2. The RF system of claim 1 wherein said translation element comprises:

a hinge pin having first and second opposing surfaces with a first or top surface of said hinge pin having a hole provided therethrough;

a pair of yoke blocks movably coupled to and projecting from opposing ends of said hinge pin, said yoke blocks coupled to a first one of said first and second heat sink assemblies;

a screw disposed through the hole in said hinge pin and coupled to a second one of said first and second heat sink assemblies; and

a spring disposed over the shank of the screw.

3. The RF system of claim 1 wherein said rotating assembly comprises:

a pair of yoke blocks rotatably coupled to said translation element and coupled to a first one of said first and second heat sink assemblies such that said second heat sink assembly can rotate about said translation element.

4. The RF system of claim 1 wherein said translation element comprises:

a hinge pin having a bore therethrough;

a screw disposed through the bore in said hinge pin; and

a spring disposed over the screw with a first end of said spring disposed against a first surface of said hinge pin.
