Description

Technical Field

[0001] This application relates to the field of power distribution, and more specifically, to busbar assemblies used to electrically connect electrical equipment to a power supply unit. Background Technology

[0002] Busbar assemblies serve as power paths for electrical connections between multiple electrical devices, such as connecting electrical equipment to a power supply unit in a power distribution system. In busbar assemblies used in power supply systems, the power busbar and the grounding circuit busbar are electrically isolated by an isolator. In the prior art, to secure the busbar element, consisting of the power busbar, grounding circuit busbar, and isolator, to the housing, isolators and bolts are typically installed between the housing and the power busbar, and between the housing and the grounding circuit busbar. The bolts and isolators are used to lock the power busbar and the grounding circuit busbar to the housing, respectively, thereby achieving fixation.

[0003] However, fixing the power bus and grounding circuit bus to the housing separately will cause the power bus and grounding circuit bus to peel off from the isolation plate, making it impossible to reliably fix the bus components.

[0004] Therefore, it is desirable to design an improved bus assembly to solve the above problems. Utility Model Content

In the left-right direction perpendicular to the vertical direction, the isolation plate is disposed between the first bus and the second bus to electrically isolate the first bus and the second bus. In the left-right direction, the first bus has a first through hole, the second bus has a second through hole, and the isolation plate has a third through hole. The first through hole, the second through hole, and the third through hole correspond to each other in the left-right direction. The mounting member includes a first mounting member installed in the first through hole of the first bus and a second mounting member installed in the second through hole of the second bus. The fixing member passes through the first mounting member, the third through hole of the isolation plate, and the second mounting member to fix the mounting member, the first bus, the second bus, and the isolation plate.

[0007] Furthermore, the diameter of the third through hole is smaller than that of the first through hole and the second through hole. The first mounting member and the second mounting member are provided with a fourth through hole for the fixing member to pass through. The diameter of the third through hole is approximately the same as that of the fourth through hole.

[0008] Furthermore, mounting grooves are respectively formed on the left and right sides of the isolation plate, and the first busbar and the second busbar are respectively embedded and adhered in the corresponding mounting grooves of the isolation plate.

[0009] Furthermore, the first busbar, the second busbar, and the isolation plate constitute a busbar element. The busbar assembly also includes a housing that houses the busbar element. The housing includes a pair of sidewalls and a rear wall connected to the rear ends of the pair of sidewalls. The pair of sidewalls are respectively located outside the first busbar and the second busbar. The fastener fixes the first mounting member, the first busbar, the isolation plate, the second busbar, and the second mounting member relative to the pair of sidewalls.

[0010] Furthermore, one end of the first mounting member passes through the first through hole of the first busbar and abuts against the first side of the isolation plate, and one end of the second mounting member passes through the second through hole of the second busbar and abuts against the second side of the isolation plate.

[0013] Furthermore, in the front-rear direction, both the first busbar and the second busbar include a thick portion and a thin portion extending forward from the thick portion. A pair of first mounting members are respectively disposed near the front and rear ends of the thick portion of the first busbar, and a pair of second mounting members are respectively disposed near the front and rear ends of the thick portion of the second busbar.

[0023] The following detailed embodiments will further illustrate the present application in conjunction with the above accompanying drawings.

[0024] With reference Figures 1 to 6As shown, this application discloses a bus assembly 100 for electrically connecting electrical devices. For example, the bus assembly 100 can be used in a power distribution system to electrically connect electrical devices to a power supply unit. As an example, the bus assembly 100 can be used in a data center or server rack, where a power supply unit (PSU) supplies power to various electrical devices through the bus assembly. The bus assembly can be a vertical bus assembly in the rack that distributes power to various electrical devices.

[0025] The bus assembly 100 includes a first bus 1, a second bus 2, an isolation plate 3, an insulating mounting member 4, a fixing member 5, and a housing 6 extending in a vertical direction. The first bus 1 is a power bus, and the second bus 2 is a grounding circuit bus. In a left-right direction perpendicular to the vertical direction, the isolation plate 3 is disposed between the first bus 1 and the second bus 2 to electrically isolate them. Mounting grooves 31 are respectively formed on the left and right sides of the isolation plate 3, and the first bus 1 and the second bus 2 are respectively embedded and adhered to the corresponding mounting grooves 31 of the isolation plate 3.

[0026] In the left-right direction, the first busbar 1 has a first through hole 101, the second busbar 2 has a second through hole 201, and the partition plate 3 has a third through hole 301. The first through hole 101, the second through hole 201, and the third through hole 301 correspond to each other in the left-right direction. The mounting member 4 includes a first mounting member 41 installed in the first through hole 101 of the first busbar 1 and a second mounting member 42 installed in the second through hole 201 of the second busbar 2. The fixing member 5 passes through the first mounting member 41, the third through hole 301 of the partition plate 3, and the second mounting member 42 to fix the mounting member 4, the first busbar 1, the second busbar 2, and the partition plate 3. The first busbar 1, the second busbar 2, and the partition plate 3 together constitute a busbar element 700, and the busbar element 700 is reliably fixed as a whole through the first mounting member 41, the second mounting member 42, and the fixing member 5.

[0027] The diameter of the third through hole 301 of the isolation plate 3 is smaller than the diameter of the first through hole 101 of the first busbar 1 and the second through hole 201 of the second busbar 2. The first mounting member 41 and the second mounting member 42 are provided with a fourth through hole 401 for the fixing member 5 to pass through. Preferably, the diameter of the third through hole 301 of the isolation plate 3 is approximately the same as the diameter of the fourth through hole 401 of the first mounting member 41 and the second mounting member 42. The circumferential dimension of the fixing member 5 is equivalent to the diameters of the third through hole 401 and the fourth through hole 401. In this way, the fixing member 5 can restrict the vertical movement of each of the first busbar 1, the second busbar 2 and the isolation plate 3, thereby ensuring a tight fixation between the first busbar 1, the second busbar 2 and the isolation plate 3.

[0028] The housing 6 houses the busbar element 700. The housing 6 includes a pair of sidewalls 61a and 61b and a rear wall 62 connected to the rear ends of the sidewalls. Sidewall 61a is located outside the first busbar 1, and sidewall 61b is located outside the second busbar 2. The fixing member 5 fixes the first mounting member 41, the first busbar 1, the partition plate 3, the second busbar 2, and the second mounting member 42 relative to the pair of sidewalls 61a and 61b. That is, the busbar element 700 is fixed to the pair of sidewalls 61a and 61b of the housing 6 by the first mounting member 41, the second mounting member 42, and the fixing member 5. In this invention, the fixing member 5 consists of a bolt 51 and a nut 52.

[0029] One end of the first mounting member 41 passes through the first through hole 101 of the first busbar 1 and abuts against the first side 31a of the isolation plate 3. One end of the second mounting member 42 passes through the second through hole 201 of the second busbar 2 and abuts against the second side 31b of the isolation plate 3. That is, the first mounting member 41 only passes through the first busbar 1 and does not pass through the isolation plate 3, and the second mounting member 42 only passes through the second busbar 2 and does not pass through the isolation plate 3. Specifically, in the left-right direction, the first mounting member 41 includes a first abutting portion 411 abutting against the outside of the first busbar 1 and a first insertion portion 412 extending from the first abutting portion 411 and installed in the first through hole 101. The right end of the first insertion portion 412 abuts against the first side 31a of the isolation plate 3. The first abutting portion 411 is disposed between the first busbar 1 and the side wall 61a of the housing 6 to prevent the first busbar 1 from being short-circuited with the housing 6. In the left-right direction, the second mounting member 42 includes a second abutting portion 421 abutting against the outside of the second busbar 2 and a second insertion portion 422 extending from the second abutting portion 421 and disposed in the second through hole 201. The right end of the second insertion portion 422 abuts against the second side 31b of the partition plate 3. The second abutting portion 421 is disposed between the second busbar 2 and the side wall 61b of the housing 6. The first abutting portion 411 and the second abutting portion 421 allow the busbar element 700 to be reliably clamped between a pair of side walls 61a and 61b of the housing 6.

[0030] In a preferred embodiment of this utility model, in the front-back direction perpendicular to the vertical and horizontal directions, the first busbar 1 is provided with at least one pair of first through holes 101, the second busbar 2 is provided with at least one pair of second through holes 201, and the partition plate 3 is provided with at least one pair of third through holes 301. Correspondingly, the first mounting member 41 is provided with a pair corresponding to the pair of first through holes 101, and the second mounting member 42 is provided with a pair corresponding to the pair of second through holes 201. The pair of first mounting members 41 are connected by a first connecting part 413, which is disposed between one side wall 61a of the housing 6 and the first busbar 1 to further prevent short circuit between the first busbar 1 and the housing 6. Similarly, the pair of second mounting members 42 are connected by a second connecting part 423, which is disposed between the other side wall 61b of the housing 6 and the second busbar 2 to cooperate with the first connecting part 413 so that the busbar element 700 is reliably clamped by the housing 6 by the fixing member 5.

[0031] In the front-to-back direction, the first busbar 1 includes a first thick portion 11 and a first thin portion 12 extending forward from the first thick portion 11, which is thinner than the first thick portion 11. A pair of first mounting members 41 are respectively disposed near the front and rear ends of the first thick portion 11 of the first busbar 1. The second busbar 2 includes a second thick portion 21 and a second thin portion 22 extending forward from the second thick portion 21, which is thinner than the second thick portion 21. A pair of second mounting members 42 are respectively disposed near the front and rear ends of the second thick portion 21 of the second busbar 2. Several pairs of first mounting members 41 and second mounting members 42 are respectively disposed on the first busbar 1 and the second busbar 2 in the vertical direction. The number of fixing members 5 corresponds to the number of first mounting members 41 and second mounting members 42, thereby improving the stable holding between the busbar element 700 and the housing 6. The bus assembly 100 further includes a grounding mounting member 8. The grounding mounting member 8 includes a grounding block 81 disposed between the second bus 2 (serving as a grounding loop bus) and the side wall 61b of the housing 6, and a locking member 82 that passes through the housing 6 but does not penetrate the second bus 2. The locking member 82 reliably clamps the grounding block 81 between the second bus 2 and the side wall 61b, thereby ensuring the electrical connection between the second bus 2 and the housing 6 and improving the grounding effect of the bus assembly 100. Furthermore, the grounding mounting member 8 also includes a locking member 83 that stably fixes the grounding block 81 to the second bus 2 on the inner side of the side wall 61b of the housing 6. The locking member 83 is located on both sides of the locking member 82 in the front-rear direction, and the locking member 83 also does not penetrate the second bus. The housing 6 has a pair of sidewalls 61a and 61b forming slots 63a and 63b between the first thin portion 12 and the second thin portion 22, respectively. The inner surfaces of the pair of sidewalls 61a and 61b are provided with grounding aluminum plates 9 extending in the vertical direction within the corresponding slots 63a and 63b. The grounding aluminum plates 9 are used to ground when a mating connector (not shown) adapted to the bus assembly 100 is inserted.

[0032] In summary, the above are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Any simple equivalent changes and modifications made in accordance with the claims and description of the present utility model should still fall within the scope of the present utility model patent.
