Detailed Description of the Embodiments

[0017] The technical solutions in the embodiments of the present utility model will be described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments.

[0018] The present utility model relates to an AC power adapter, which can be used in the case of 480V alternating current, so as to achieve a significant power increase at a relatively low current. In this embodiment, the alternating current can be 100A.

[0019] Reference Figure 1-4 As shown, the power adapter 100 of the first embodiment of this utility model includes a first connector 10A and a second connector 20A electrically connected to each other. The first connector 10A includes a plurality of mating grooves 11 and a plurality of first terminals 20. Each mating groove 11 extends forward and simultaneously extends vertically, and the plurality of mating grooves 11 are arranged in a left-right direction. Each first terminal 20 includes an elastic arm 21 and a first tail 22. The elastic arm 21 has a contact portion 211 protruding into the mating groove 11. The second connector 20A includes a plurality of mating holes 12 and a plurality of second terminals 30. Each mating hole 12 extends backward, and each second terminal 30 includes a mating post 31 and a second tail 32. The mating post 31 of the second terminal is located within the mating hole 12, and the second tail 32 and the first tail 22 are electrically connected to each other. The left-right direction is shown as XX direction, the vertical direction is shown as YY, and the front-back direction is shown as ZZ.

[0020] In use, multiple power busbars (also known as power bus bars in the industry) receive 480V AC power. The busbars are inserted into corresponding docking slots 11 to contact the first terminal 20, and then transmitted to the power supply unit (PSU) via the second terminal 30. In this embodiment, the AC power is transmitted in a three-phase four-wire configuration on the busbar input side and in a three-phase five-wire configuration on the output side, reducing risk. In other embodiments, other configurations may be used, such as a three-phase seven-wire configuration. The busbars are generally designed with a slender structure; for ease of description, the slender extension direction of the busbar is vertical, and the mating direction between the busbar and the docking slot 11 is front-to-back. The docking slot 11 extends vertically to facilitate the extension of the busbar.

[0021] The power adapter of this invention has a first terminal on one side configured as a busbar terminal and a second terminal on the other side configured as a column terminal, thereby transmitting high-voltage power and achieving high power by increasing voltage, thus avoiding the situation of increasing power by increasing current.

[0022] In this invention, the power adapter is configured as an AC adapter, with AC power entering the power supply rack via a busbar. Power is increased by boosting the voltage, thereby achieving a safer design.

[0023] In this embodiment, the power adapter 100 includes an insulating body 10, a mating groove 11 disposed at the front end of the insulating body 10, and a mating hole 12 disposed at the rear end of the insulating body 10. In this embodiment, the insulating body is formed by assembling multiple insulating blocks; for example, the first terminal 20 is fixed to one insulating block, the second terminal 30 is fixed to another insulating block, and the two insulating blocks are then assembled into one unit. In other embodiments, the insulating body can be a single piece.

[0024] Further, the power adapter 100 includes a plurality of conductive adapter pieces 40, which are electrically and mechanically connected to the corresponding first tail portion 22 and the corresponding second tail portion 32. By arranging the conductive adapter pieces 40, the alternating current transfer is realized, and the arrangement of the first and second adapters is simplified at the same time.

[0025] In this embodiment, the insulating body 10 is provided with four mating grooves 11 and five mating holes 12, wherein one side wall of the mating groove 11 at the outermost side is cut off to form a ground mating groove 11A, and the first terminal 20 located in the ground mating groove 11A is electrically and mechanically connected to two corresponding second tail portions 32 through two conductive adapter pieces 40 respectively. The four mating grooves are sequentially arranged as L1, L2, L3, and PE from left to right, and the ground mating groove 11A is located at the outermost side, which facilitates the mating between the busbar and the mating grooves.

[0026] Further, each first terminal 20 is made of a metal sheet, and the first tail portion 32 and the elastic arm 31 have the same width in the up-down direction.

[0027] Further, the elastic arms 21 of the first terminals are located on the same side of the corresponding mating grooves 11, and the elastic arms are not arranged on the opposite other side.

[0028] Further, an insulating cap 50 is fixed to the other end of each mating post 31 facing away from the second tail portion 32. The insulating cap can not only play a guiding role, but also avoid high-voltage electric arcs at the moment of contact.

[0029] In this embodiment, the insulating body is provided with two locking heads 13, which are respectively located on the left and right sides of the mating holes 12.

[0030] See Figure 5 as shown, the first connector 10B according to the second embodiment of the present utility model is provided with four mating grooves 11, and its ground mating groove 11B is constituted by left and right side walls.

[0031] See Figure 6 as shown, the first connector 10C according to the third embodiment of the present utility model is provided with five mating grooves 11 for transmitting three-phase five-wire alternating current. A grounding frame 60 is arranged on the outer side of the insulating body.

[0032] See Figure 7 as shown, the second connector 20D according to the fourth embodiment of the present utility model is provided with four mating holes 12 for outputting three-phase four-wire alternating current.

[0033] See Figure 8As shown, the power adapter 100E of the fifth embodiment of this utility model has a first connector composed of multiple third terminals 70. The third terminals 70 are directly inserted into the fixing holes provided on the busbar for fixation, thereby achieving the function of current transmission. Its second connector consists of four second terminals 30, each second terminal connecting to two third terminals 70. Each third terminal 70 includes a mating post 71 and a third tail 72, with the third tail 72 directly contacting the second tail 32. This simplifies the connection between the adapter and the busbar.

[0034] 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.
