Abstract

A bracket includes a bracket housing that has a bore extending through the bracket housing and that has a channel extending through the bracket housing between a first channel opening and a second channel opening. The bore provides fluid communication between the power electronic device and the compressor assembly. A terminal block subassembly is disposed in the channel. The terminal block subassembly includes a plurality of busbars spaced apart from each other and each extending between a first busbar end and a second busbar end. An overmold encasement is disposed over the busbars between the first and second busbar ends. The first busbar ends are disposed adjacent to the first channel opening and electrically couple to a compressor assembly and the second busbar ends are disposed adjacent to the second channel opening and electrically couple to a power electronic device.

Claims (41)

1 . A bracket for coupling a power electronic device to a compressor assembly, the bracket comprising:

a bracket housing that has a bore extending through the bracket housing and that has a channel spaced apart from the bore and extending through the bracket housing between a first channel opening and a second channel opening, wherein the bore is configured to provide fluid communication between the power electronic device and the compressor assembly; and

a terminal block subassembly disposed in the channel extending between the first and second channel openings and comprising:

a plurality of busbars spaced apart from each other and each extending between a first busbar end and a second busbar end; and

an overmold encasement disposed over the busbars between the first and second busbar ends, wherein the first busbar ends are disposed adjacent to the first channel opening and are configured to electrically couple to the compressor assembly and the second busbar ends are disposed adjacent to the second channel opening and are configured to electrically couple to the power electronic device.

2 . The bracket of claim 1 , wherein the bracket housing comprises:

a first axial extending body portion having the bore extending therethrough;

a second axial extending body portion disposed adjacent to the first axial extending body portion and having the channel extending therethrough; and

a web portion disposed between and coupling the first and second axial extending body portions.

3 . The bracket of claim 2 , wherein the terminal block subassembly is configured as an elongated, axially extending block that is disposed in the channel of the second axial extending body portion of the bracket housing.

4 . The bracket of claim 2 , wherein the bracket housing comprises a substantially “H-shaped” cross-section.

5 . The bracket of claim 1 , wherein the bracket housing is formed of metal.

6 . The bracket of claim 5 , wherein the metal comprises aluminum or an aluminum alloy.

7 . The bracket of claim 1 , wherein the overmold encasement is formed of a plastic material.

8 . The bracket of claim 7 , wherein the plastic material comprises a polyphenylene sulfide polymeric material, a polyester polymeric material, a polyamide polymeric material, glass fibers, fillers, or a combination thereof.

9 . The bracket of claim 1 , wherein the busbars comprise a first busbar, a second busbar, and a third busbar that are spaced apart from each other.

10 . The bracket of claim 1 , wherein the terminal block subassembly extends through the first channel opening and the first busbar ends of the busbars are disposed outside of the bracket housing adjacent to the first channel opening.

11 . A bracket for coupling a power electronic device to a compressor assembly, the bracket comprising:

a terminal block subassembly disposed in the channel extending between the first and second channel openings and comprising:

a plurality of busbars spaced apart from each other and each extending between a first busbar end and a second busbar end; and

12 . A power electronic device and compressor assembly arrangement comprising:

a power electronic device;

a compressor assembly; and

a bracket that couples the power electronic device to the compressor assembly, wherein the bracket comprises:

a terminal block subassembly disposed in the channel extending between the first and second channel openings and comprising:

a plurality of busbars spaced apart from each other and each extending between a first busbar end and a second busbar end; and

an overmold encasement disposed over the busbars between the first and second busbar ends, wherein the first busbar ends are disposed adjacent to the first channel opening and are electrically coupled to the compressor assembly and the second busbar ends are disposed adjacent to the second channel opening and are electrically coupled to the power electronic device.

13 . The power electronic device and compressor assembly arrangement of claim 12 , wherein the power electronic device is an inverter.

14 . The power electronic device and compressor assembly arrangement of claim 13 , wherein the busbars comprise a first busbar, a second busbar, and a third busbar, and wherein the inverter is configured as a three-phase power electronic device.

15 . The power electronic device and compressor assembly arrangement of claim 12 , wherein the bracket is fastened to the power electronic device and independently, is fastened to the compressor assembly.

16 . The power electronic device and compressor assembly arrangement of claim 12 , wherein the first busbar ends of the busbars are electrically coupled directly to the compressor assembly.

17 . The power electronic device and compressor assembly arrangement of claim 12 , wherein the first busbar ends of the busbars are electrically coupled indirectly to the compressor assembly via an adapter.

18 . The power electronic device and compressor assembly arrangement of claim 12 , further comprising a heat transfer fluid that is fluidly communicated through the bore of the bracket housing from the power electronic device to the compressor assembly.

19 . The power electronic device and compressor assembly arrangement of claim 12 , wherein the bracket housing is formed of metal and is configured to block an electromagnetic field(s) about the channel.

20 . The power electronic device and compressor assembly arrangement of claim 12 , wherein the bracket housing comprises:

a first axial extending body portion having the bore extending therethrough;

a second axial extending body portion disposed adjacent to the first axial extending body portion and having the channel extending therethrough; and

a web portion disposed between and coupling the first and second axial extending body portions.
