[0019] The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings. Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] The present invention is a power connector assembly 100 that can transmit alternating current. In a specific embodiment, the alternating current input end transmits alternating current to a power supply unit (PSU), and the power supply unit converts and outputs direct current. The output direct current is transmitted to the DC distribution bus through a rack busbar clip. The DC distribution bus may be a bus bar as known in the industry, and then is distributed to each server. In this embodiment, the alternating current is distributed to multiple power supply units through the power connector assembly 100 of the present invention.

[0022] Refer Figure 1-9 As shown, a power connector assembly 100 according to an embodiment of the present invention includes a circuit board 10, a first power connector 20, and at least two second power connectors 30. The circuit board 10 is vertically arranged and has opposite front surface 11 and rear surface 12. In this embodiment, the circuit board 10 is disposed in a housing at one end of a PSU shelf, and generally multiple power supply units are disposed in the PSU shelf.

[0023] The first power connector 20 is mounted on the front surface 11 of the circuit board 10 and has a first pair of interfaces 211 that penetrate forward. The first power connector 20 includes a first insulating body 21 and a plurality of first power terminals 22 arranged vertically. Each second power connector 30 includes a second insulating body 31 and a plurality of second power terminals 32 arranged horizontally. Each second power connector 30 has a second pair of interfaces 311 that penetrate backward. At least two second power connectors 30 are arranged vertically, and each second power connector 30 is electrically connected to the first power connector 20 through a power line 13 provided on the circuit board 10, which is only partially shown by a dotted line in the drawing and is generally a gold foil conductive structure on the circuit board.

[0024] A card 51 at one end of a power supply (not shown) can be inserted into a second pair of interfaces 311. The input AC power enters from the first power connector 20, and can be distributed to at least two power supplies via the circuit board 10 and the second power connector 30. Directly distributing power to multiple second power connectors using the circuit board simplifies power conversion and transmission.

[0025] The first power connectors 20 are arranged vertically, thus making full use of the power supply bracket housing. As in the second embodiment, refer to... Figure 10 The same circuit board 10 has two first power connectors 20.

[0026] More specifically, the first power connector 20 is an input-side AC power connector, and the second power connector 20 is an output-side AC power connector. Compared to the AC power transmission defined in ORV3 AC WHIP OCP Specification Rev 1.0, the first power connector 20 of this invention is mounted on the power supply rack, directly shunting the AC power through the circuit board, thus simplifying AC power transmission.

[0027] In this embodiment, three second power connectors 30 are included, arranged vertically. Thus, one first power connector 20 can distribute power to three power supplies, increasing the utilization rate of AC power. In this embodiment, under a 480V AC voltage environment, 100A of power is distributed to the three edge-mounted power connectors.

[0028] More specifically, the first power terminal 22 is a cylindrical terminal; the second power terminal 32 is a sheet terminal. The cylindrical terminal of the first power terminal is suitable for general high-current transmission; the sheet terminal can reduce the manufacturing cost of the second power connector.

[0029] In this embodiment, the second power connector is a snap-on power connector, which uses a commonly used power connector with power redundancy, thus not increasing the cost.

[0030] In the first embodiment of the present invention, as Figure 1-9 As shown, a reinforcing plate 40 is attached to the rear surface 12 of the circuit board 10. The circuit board 10 and the reinforcing plate 40 have a through-hole 41. The second power terminal 32 is inserted into the circuit board 10 from front to back, and the second insulating body 31 protrudes from the rear surface 12 of the circuit board through the through-hole 41. In other embodiments, the second power terminal 32 may be soldered to the front surface 11 of the circuit board, and the second insulating body protrudes from the rear surface 12 of the circuit board through the through-hole 41.

[0031] Specifically, the first insulating body 21 is provided with a plurality of circular cavities 212, and the second power terminal 22 includes a columnar docking portion 221 that protrudes into the circular cavity 212. The plurality of circular cavities 221 are spaced apart from each other, which can prevent the high-voltage arcs between the first power terminals 22 from affecting each other. The second power terminal 22 includes a columnar connection portion 223 at the rear end and a flange portion 222 in the middle. The flange portion 222 is fixed within the first insulating body 21, and the columnar connection portion 223 protrudes out of the first insulating body 21. The circuit board 10 is provided with a first conductive hole 14, and a row of columnar connection portions 223 are respectively corresponding to the inside of the first conductive hole 14 to achieve electrical connection.

[0032] Specifically, the second insulating body 31 is provided with a card slot 312. The second power terminal 32 includes a fixing portion 322 fixed to the second insulating body, a plurality of elastic arms 321 extending from the fixing portion, and a plurality of connection portions 323. The elastic arms are provided with contact portions 3211 that protrude into the card slot 312. Thus, the edge-clamping type power connector is formed. In the first embodiment, the fixing portion is a U-shaped structure. Thus, the connection portions 323 and the extending directions of the elastic arms 321 are the same, and the edge-clamping type power connector can be a sunken type. Of course, in the second embodiment, the connection portions are SMT form pins and are directly welded to the rear surface 12 of the circuit board 10. The circuit board 10 is provided with multiple rows of second conductive holes 15, and the connection portions 323 are inserted into the second conductive holes 15 to achieve electrical connection. The connection portions 323 of each second power terminal are multi-pin type connection portions.

[0033] The first power connector 20 includes four first power terminals 22, which are arranged in sequence as the first terminal 22PE / N, the second terminal 22-1, the third terminal 22-2, and the fourth terminal 22-3. The first terminal 22PE / N can be a grounding terminal or a negative terminal, and the second to fourth terminals are positive terminals, which conform to the definition of three-phase four-wire AC input.

[0034] Refer Figure 6 As shown, two lock nuts 231 are respectively installed at the upper and lower ends inside the first insulating body 21 for locking with the bolts on the docking plug. Two lock plate nuts 232 are respectively installed at the upper and lower ends inside the first insulating body 21, and the lock plate nuts fix the first insulating body on the circuit board 10.

[0035] In the second embodiment of the present invention, as Figure 10-11 , shown, two first power connectors 20 are provided on the same circuit board 10. Each first power connector is vertically arranged, and the two first power connectors are arranged side by side in the horizontal direction. The second power terminal 32A is welded to the rear surface 12 of the circuit board 10. Among the three-phase four-wire first power terminals, among the second to fourth terminals, each terminal is further split into two sheet-like terminals, and two gold fingers 51-3 are provided corresponding to the card board. Thus, the power input can be increased.

[0036] In summary, the above are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the claims and description of the present invention should still fall within the scope of the patent of the present invention.
