Description

TECHNICAL FIELD

This disclosure relates to power connectors and, more particularly, to displaceable power connectors.

BACKGROUND

In today's IT infrastructure, high availability is of paramount importance. Specifically, critical (and sometimes non-critical) components within an IT infrastructure are often layered in redundancy. For example, primary servers may be supported by backup servers; primary switches may be supported by backup switches; primary power supplies may be supported by backup power supplies; and primary storage systems may be supported by backup storage systems.

Oftentimes, various IT components are configured to be quickly inserted into and removed from various rack enclosures. Accordingly, hard drive modules, power supply modules, and computing modules may be configured to be quickly placed into and removed from frame assemblies. Accordingly, these frame assemblies (and the modules that mate with them) must include the appropriate electrical connections so that when the modules are installed into the frame assemblies, all of the required electrical connections are made for the device to function properly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1-2, there is shown module assembly 10 and frame assembly 12, wherein module assembly 10 is removably positionable within frame assembly 12. Examples of frame assembly 12 may include but are not limited to frame assemblies that are capable of being mounted into IT cabinetry (e.g. racks, cabinets, enclosures). Examples of module assembly 10 may include but are not limited to various IT componentry that would be removably positionable within frame assembly 12, such as hard disk drive module assemblies, processing module assemblies, power supply module assemblies, and controller module assemblies.

Accordingly, frame assembly 12 may be configured as a power supply and module assembly 10 may include a battery assembly and be configured to be removably coupleable to frame assembly 12. Alternatively, frame assembly 12 may be a storage subsystem and module assembly 10 may include a hard disk drive and be configured to be removably coupleable to frame assembly 12.

As module assembly 10 is configured to be repeatedly inserted into and removed from frame assembly 12, frame assembly 12 may include a robust electrical connector assembly that may allow for automated alignment of the electrical connectors that couple frame assembly 12 and module assembly 10.

Referring also to FIG. 3-4, there is shown adaptive connector assembly 14 that is included within (in this embodiment) frame assembly 12. Alternatively, adaptive connector assembly 14 may be included within module assembly 10. In this particular embodiment of adaptive connector assembly 14, adaptive connector assembly 14 is shown to include two electrical connectors, namely pin connectors 16, 18. The ends of pin connectors 16, 18 maybe be tapered to aid in aligning pin connectors 16, 18 with corresponding female connectors (not shown) on module assembly 10. A typical embodiment of pin connectors 16, 18 would be that of a ground connector and a DC voltage connector. For example, pin connector 16 may be configured to provide a ground connection to module assembly 10 and pin connector 18 may be configured to provide a 12 VDC electrical connection to module assembly 10.

While in this particular example, adaptive connector assembly 14 is shown to include only two electrical connections (namely pin connectors 16, 18), this is for illustrative purposes only and is not intended to be a limitation of this disclosure. For example, additional electrical connectors may be included to provide e.g. data coupling functionality between frame assembly 12 and module assembly 10.

In order to allow module assembly 10 to slide into frame assembly 12, there should be some clearance between frame assembly 12 and module assembly 10. Accordingly, module assembly 10 should be a little bit smaller than frame assembly 12 or frame assembly 12 should be a little bit bigger than module assembly 10. Such clearance may be required in order to allow module assembly 10 to easily slide into frame assembly 12. Unfortunately, while clearance allows for easier insertion of module assembly 10 into frame assembly 12, such clearance also results in potential connector misalignment issues between the electrical connectors on module assembly 10 and the corresponding electrical connectors on frame assembly 12. Accordingly, adaptive connector assembly 14 may be configured to be displaceable in three axes.

Referring also to FIGS. 5-7, there are shown more detailed views of adaptive connector assembly 14. Adaptive connector assembly 14 may include one or more compliance assemblies (compliance assemblies 20, 22, 24, 26) that allow for the movement of connector assembly 14 (and therefore pin assemblies 16, 18) in all three axes (as will be explained).

Adaptive connector assembly 14 may be provided with power by (in this embodiment) multi-conductor power cable 28 that (in this embodiment) provides power to pin connectors 16, 18. In this particular environment, pin connectors 16, 18 are attached to backplane 30, which is attached (via compliance assemblies 20, 22, 24, 26) to frame assembly 12. As shown in FIGS. 5-7, each compliance assembly includes (in this embodiment) screw portion 32, nut portion 34, and spring portion 36. While in this particular embodiment, compliance assembly 20 is shown to include screw portion 32, nut portion 34 and spring portion 36, this is for illustrative purposes only and is not intended to be a limitation of this disclosure, as other configurations are possible and it is the function of the compliance assembly that is more important than the actual components used to make the compliance assembly. In this particular example, the function of the combination of screw portion 32 and nut portion 34 is to capture spring portion 36 and provide a clamping force that biases backplane assembly 30 against frame assembly 12. Additionally, the hole in backplane assembly 30 through which screw portion 32 passes may be larger than the shank of screw portion 32 (while not as large as the diameter of spring portion 36). Accordingly, through the use of an oversized hole in backplane assembly 30 and/or an undersized screw portion 32, displacement of adaptive connector assembly 14 is achievable in the X axis and the Y-axis, as backplane assembly 30 may be displaced with respect to the screw portions of compliance assemblies 20, 22, 24, 26. Additionally, as spring portion 36 may be compressible in the Z-axis, adaptive connector assembly 14 may be displaceable in the Z-axis when adaptive connector assembly 14 comes in contact with module assembly 10.

One or more energy absorption assemblies 38, 40 may be positioned on frame assembly 12 so that when module assembly 10 is slid into frame assembly 12, energy absorption assemblies 38, 40 (which may be configured as leaf springs) absorb a portion of the impact energy of module assembly 10 striking the back of frame assembly 12.

Having thus described the disclosure of the present application in detail and by reference to embodiments thereof, it will be apparent that modifications and variations are possible without departing from the scope of the disclosure defined in the appended claims.
