Abstract

An apparatus includes a rigid structure having first and second collars, a quick connect connector having first and second shoulders, and a spring biasing the connector toward an extended position with the first shoulder against the first collar and the second shoulder against the second collar. The first collar and the first shoulder form an inwardly and rearwardly angled contact surface there between, and the second collar and the second shoulder form an inwardly and rearwardly angled contact surface there between. The connector is centered in the first and second collars unless acted upon by a force overcoming the spring and pushing the connector to a retracted position with the first and second shoulders out of contact with the first and second collars. When retracted, the connector may adjust its position longitudinally, vertically, laterally or angularly to facilitate coupling with a mating fixed quick connect connector.

First claim

What is claimed is:

1. An apparatus comprising:
a chassis including a fluid supply conduit, a fluid return conduit, a first quick connect connector that is fluidically coupled to the fluid supply conduit, a second quick connect connector that is fluidically coupled to the fluid return conduit, and a bay configured to receive a compute node, wherein the first and second quick connect connectors are secured in a fixed position at a back of the bay and oriented in a forward direction into the bay;
a compute node having a rearward end securing a first compliant connector assembly and a second compliant connector assembly, wherein the first compliant connector assembly includes a third quick connect connector oriented in a rearward direction so that installing the compute node within the bay provides nominal alignment of the third quick connect connector with the first quick connect connector, and wherein the second compliant connector assembly includes a fourth quick connect connector oriented in a rearward direction so that installing the compute node within the bay provides nominal alignment of the fourth quick connect connector with the second quick connect connector;
wherein the first compliant connector assembly includes a rigid structure having first and second collars, wherein the third quick connect connector has first and second shoulders, wherein the first collar and the first shoulder form an inwardly and rearwardly angled contact surface there between, wherein the second collar and the second shoulder form an inwardly and rearwardly angled contact surface there between, and wherein the first compliant connector assembly further includes a first spring biasing the third quick connect connector in the rearward direction; and
wherein the second compliant connector assembly includes a rigid structure having first and second collars, wherein the fourth quick connect connector has first and second shoulders, wherein the first collar and the first shoulder form an inwardly and rearwardly angled contact surface there between, wherein the second collar and the second shoulder form an inwardly and rearwardly angled contact surface there between, and wherein the second compliant connector assembly further includes a second spring biasing the fourth quick connect connector in the rearward direction.

2. The apparatus of claim 1 , wherein the first and second collars each form an inwardly and rearwardly angled surface.

3. The apparatus of claim 2 , wherein the first and second collars each form a frustoconical surface.

4. The apparatus of claim 1 , wherein the third quick connect connector is centered in the first and second collars of the first compliant connector assembly unless acted upon by a force overcoming the first spring and pushing the first and second shoulders of the third quick connect connector out of contact with the first and second collars of the first compliant connector assembly; and
wherein the fourth quick connect connector is centered in the first and second collars of the second compliant connector assembly unless acted upon by a force overcoming the first spring and pushing the first and second shoulders of the fourth quick connect connector out of contact with the first and second collars of the second compliant connector assembly.

5. The apparatus of claim 1 , wherein the third quick connect connector is allowed to tilt to various angles in order to align with the first quick connect connector despite any initial misalignment between the first and third quick connect connectors; and
wherein the fourth quick connect connector is allowed to tilt to various angles in order to align with the second quick connect connector despite any initial misalignment between the second and fourth quick connect connectors.

6. The apparatus of claim 1 , wherein, when the third quick connect connector is in a retracted position, the first compliant connector assembly allows the third quick connect connector to move in a lateral direction, vertical direction, longitudinal direction and at an angle relative to a longitudinal axis defined by an extended position of the third quick connect connector; and
wherein, when the fourth quick connect connector is in a retracted position, the first compliant connector assembly allows the fourth quick connect connector to move in a lateral direction, vertical direction, longitudinal direction and at an angle relative to a longitudinal axis defined by an extended position of the fourth quick connect connector.

7. The apparatus of claim 1 , wherein the compute node includes a cooling circuit coupled between the third and fourth quick connect connectors.

8. The apparatus of claim 1 , wherein each of the quick connect connectors include an automatic shut off valve that prevent fluid flow when disconnected.

9. An apparatus comprising:
a compute node configured to be received within a chassis bay; and
a first compliant connector assembly secured to a rearward end of the compute node, wherein the first compliant connector assembly includes a rigid structure having first and second collars, a first quick connect connector having first and second shoulders, and a first spring biasing the first quick connect connector in the rearward direction, wherein the first collar and the first shoulder of the first compliant connector assembly form an inwardly and rearwardly angled contact surface there between, wherein the second collar and the second shoulder of the first compliant connector assembly form an inwardly and rearwardly angled contact surface there between, and wherein the first quick connect connector is oriented in a rearward direction for blind mating with a second quick connect connector within the chassis bay.

10. The apparatus of claim 9 , further comprising:
a second compliant connector assembly secured to the rearward end of the compute node, wherein the second compliant connector assembly includes a rigid structure having first and second collars, a third quick connect connector having first and second shoulders, and a second spring biasing the third quick connect connector in the rearward direction, wherein the first collar and the first shoulder of the second compliant connector assembly form an inwardly and rearwardly angled contact surface there between, wherein the second collar and the second shoulder of the second compliant connector assembly form an inwardly and rearwardly angled contact surface there between, and wherein the third quick connect connector is oriented in a rearward direction for blind mating with a fourth quick connect connector within the chassis bay.

11. The apparatus of claim 9 , wherein the compute node includes a cooling circuit coupled between the first and second quick connect connectors.

12. The apparatus of claim 9 , wherein the first and second collars each form an inwardly and rearwardly angled surface.

13. The apparatus of claim 12 , wherein the first and second collars each form a frustoconical surface.

14. The apparatus of claim 9 , wherein the first quick connect connector is centered in the first and second collars of the first compliant connector assembly unless acted upon by a force overcoming the first spring and pushing the first and second shoulders of the first quick connect connector out of contact with the first and second collars of the first compliant connector assembly.

15. The apparatus of claim 9 , wherein the first quick connect connector is allowed to tilt to various angles in order to align with the second quick connect connector despite any initial misalignment between the first and second quick connect connectors.
