Technical Field

[0001] This application relates to a power bus group. Background Technology

[0002] A power bus assembly typically includes a bus, output-side connectors connected to the bus, and input-side connectors. The output-side connectors are used to contact or clamp mating components to provide electrical connections. However, the current method of assembling and disassembling the output-side connectors from the bus is difficult, time-consuming, and labor-intensive. Furthermore, the assembled power bus assembly with the output-side connectors and bus is relatively bulky. Utility Model Content

[0003] In view of this, this application provides a power bus assembly that is not only easy and quick to assemble, but also has a small size after assembly.

[0004] One embodiment of this application provides a power bus assembly. The power bus assembly includes two horizontally stacked buses, at least one output connector, and multiple input connectors. Both buses have horizontal tongues on the same side, and the multiple input connectors are mounted on the side of the two buses opposite to the horizontal tongues. The output connectors include an insulator, two power terminals held in the insulator, and two flexible flat cables. Each flexible flat cable includes a first end and a second end opposite to each other, and each power terminal is connected to the first end of a flexible flat cable. The power bus assembly also includes two adapters, each adapter including a horizontal portion and a vertical portion. The horizontal portion is attached to and fixed to the horizontal tongue, and the vertical portion is attached to and fixed to the second end of the corresponding flexible flat cable.

[0005] When assembling the power bus assembly, production and installation personnel only need to attach and secure the horizontal part of the "L-shaped" adapter to the horizontal tongue, and attach and secure the vertical part of the "L-shaped" adapter to the second end of the corresponding flexible flat cable to achieve conductive connection between the bus and the output connector.

The opening of the first angle faces the busbar, and the third side is closer to the output connector than the second side. The horizontal portion includes a fifth side, a sixth side, a seventh side, and an eighth side connected in sequence. Viewed perpendicular to the busbar, the fifth and eighth sides are parallel to each other, the sixth and seventh sides intersect each other, and a second angle is formed between the sixth and seventh sides. The opening of the second angle faces the vertical portion, and the seventh side is closer to the busbar than the sixth side.

[0007] In some embodiments of this application, the vertical portion is disposed adjacent to the third side and extends upward in a direction perpendicular to the busbar. Alternatively, the vertical portion is disposed spaced apart from the third side and extends upward in a direction perpendicular to the busbar.

[0008] In some embodiments of this application, the two buses include an upper bus and a corresponding lower bus, a horizontal portion of an adapter is attached to the lower surface of the horizontal tongue of the upper bus, and a horizontal portion of another adapter is attached to the upper surface of the horizontal tongue of the lower bus.

The flexible flat cable of each output-side connector is arranged in a vertical direction, and the second end of the flexible flat cable is attached to the vertical portion of the corresponding adapter in a vertical direction.

[0011] In some embodiments of this application, the power bus group further includes an insulating layer disposed between the two buses.

[0012] In some embodiments of this application, the two busbars are longitudinal structures, with multiple bends on the same side of their longitudinal length and a horizontal tongue on the other side of their longitudinal length, and each input connector is equipped with a bend.

[0013] In some embodiments of this application, the insulator is provided with a vertically extending slot, and two power terminals are respectively disposed on the left and right sides of the slot, with the rear end of each power terminal connected to the first end of the corresponding flexible flat cable.

[0019] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0020] Please refer to the following: Figures 1 to 3 One embodiment of this application provides a power bus assembly 100. The power bus assembly 100 includes two horizontally stacked busbars 10, a plurality of input-side connectors 20, at least one output-side connector 30, and two adapters 40. The two busbars 10 have a longitudinal structure, with a plurality of bends 11 on one side of their longitudinal length and a horizontal tongue 12 on the other side. Each input-side connector 20 is fitted with a corresponding bend 11. The plurality of input-side connectors 20 are used for electrical connection to a power supply unit within a server chassis. In this embodiment, one of the two busbars 10 is connected to the positive terminal (not shown) of the power supply unit via the corresponding plurality of input-side connectors 20, and the other of the two busbars 10 is connected to the negative terminal (not shown) of the power supply unit via the corresponding plurality of input-side connectors 20. Please refer to the following references. Figure 1 , Figure 3 and Figure 4 For ease of explanation, the stacking direction of the two busbars 10 is defined as the vertical direction, and the longitudinal direction of the two busbars 10 is defined as the horizontal direction. The output-side connector 30 includes an insulator 31, two power terminals 32 fixed to the insulator 31, and two flexible flat cables 33. Each flexible flat cable 33 includes a first end 331 and a second end 332 opposite to each other. The insulator 31 has a slot 311 extending vertically (i.e., in the vertical direction), and the two power terminals 32 are respectively disposed on the left and right sides of the slot 311. The rear end of each power terminal 32 is connected to the first end 331 of the corresponding flexible flat cable 33. The mating part (not shown) of an external electrical device can be inserted into the slot 311 of the output-side connector 30 and contact the power terminals 32 on the left and right sides.

[0021] Each adapter 40 includes a horizontal portion 41 and a vertical portion 42. The horizontal portion 41 is attached to and fixed to the horizontal tongue 12, and the vertical portion 42 is attached to and fixed to the second end 332 of the corresponding flexible flat cable 33. The second end 332 of the flexible flat cable 33 is located directly above the horizontal portion 41. When assembling the power bus assembly 100, the production and installation personnel only need to attach the horizontal portion 41 of the "L-shaped" adapter 40 to the horizontal tongue 12 and fix it, and attach the vertical portion 42 of the "L-shaped" adapter 40 to the second end 332 of the corresponding flexible flat cable 33 and fix it, to achieve a conductive connection between the bus 10 and the output-side connector 30. By using the "L-shaped" adapter 40, not only can the assembly of the bus 10 and the output-side connector 30 be facilitated, improving the assembly efficiency of the power bus assembly 100, but the size of the power bus assembly 100 can also be reduced, which is beneficial for miniaturization design.

[0022] The power bus assembly 100 also includes an insulating layer 50 disposed between the two busbars 10. The insulating layer 50 is used to separate the two busbars 10 (that is, to separate the positive and negative terminals) to prevent them from contacting each other and conducting electricity, thereby improving the safety of the power bus assembly 100. For example, the insulating layer 50 is an insulating sheet, which is adhered between the two busbars 10 by insulating adhesive.

[0023] Please continue to refer to the following: Figures 1 to 3 The power bus assembly 100 includes two output-side connectors 30 arranged in a vertical direction. The flexible flat cable 33 of each output-side connector 30 is arranged in a vertical direction, and the second end 332 of the flexible flat cable 33 is attached to the vertical portion 42 of the corresponding adapter 40 in a vertical direction. By providing two output-side connectors 30, the power bus assembly 100 can be electrically connected to multiple electrical devices at once, which helps to broaden the application scenarios of the power bus assembly 100.

[0024] The power bus assembly 100 also includes a fastener 60. Both the horizontal tongue 12 and the horizontal portion 41 have connection holes 70. The fastener 60 passes through the corresponding connection holes 70 to thread the horizontal portion 41 and the horizontal tongue 12 together. This threaded connection facilitates subsequent disassembly, maintenance, and replacement of the bus 10. It should be noted that the attachment and fixing between the second end 332 of the flexible flat cable 33 and the vertical portion 42 is structurally the same as the attachment and fixing between the horizontal tongue 12 and the horizontal portion 41 of the bus 10, and will not be described in detail here. In other embodiments, the attachment and fixing between the second end 332 of the flexible flat cable 33 and the vertical portion 42 may differ from the attachment and fixing between the horizontal tongue 12 and the horizontal portion 41 of the bus 10.

[0025] Please see Figure 1 The two buses 10 include an upper bus 10a and a corresponding lower bus 10b. A horizontal portion 41 of one adapter 40 is attached to the lower surface of the horizontal tongue 12 of the upper bus 10a, and a horizontal portion 41 of the other adapter 40 is attached to the upper surface of the horizontal tongue 12 of the lower bus 10b. By using an "upper and lower" attachment method, the two adapters 40 can fully utilize the vertical thickness space of the two buses 10. Even if the two adapters 40 are flush with the surfaces of their respective buses 10, the vertical thickness of the power bus assembly 100 will not increase, resulting in a compact structure and facilitating miniaturization of the power bus assembly 100.

[0026] Please refer to the following: Figure 3 , Figure 5 and Figure 6The horizontal tongue 12 includes a first side 121, a second side 122, a third side 123, and a fourth side 124 connected in sequence. Viewed perpendicular to the busbar 10, the first side 121 and the fourth side 124 are parallel to each other, while the second side 122 and the third side 123 intersect each other. A first angle α is formed between the second side 122 and the third side 123, with the opening of the first angle α facing the busbar 10. The third side 123 is closer to the output-side connector 30 than the second side 122. The horizontal portion 41 includes a fifth side 411, a sixth side 412, a seventh side 413, and an eighth side 414 connected in sequence. Viewed perpendicular to the busbar 10, the fifth side 411 and the eighth side 414 are parallel to each other, while the sixth side 412 and the seventh side 413 intersect each other. A second included angle β is formed between the sixth side 412 and the seventh side 413, with the opening of the second included angle β facing the vertical part 42. The seventh side 413 is closer to the bus 10 than the sixth side 412. By setting the horizontal tongue 12 and the horizontal part 41 to a shape similar to a "pointed roof", when assembling the power bus assembly 100, production and installation personnel can quickly determine the assembly direction between the adapter 40 and the bus 10 based on the pointed tops of the horizontal tongue 12 and the horizontal part 41. This allows the bus 10 to be quickly and accurately assembled and fixed with the output-side connector 30, which helps to improve the assembly efficiency of the power bus assembly 100.

[0027] Please see Figure 6 In this embodiment, the vertical portion 42 is disposed adjacent to the third side 123 and extends upward in a direction perpendicular to the bus 10. By disposing the vertical portion 42 adjacent to the third side 123, the adapter 40 can be placed closer to the bus 10, resulting in a more compact power bus structure and facilitating miniaturization design. Please refer to... Figure 7 In other embodiments, the vertical portion 42 is spaced apart from the third side 123 and extends upward in a direction perpendicular to the busbar 10. By spaced apart the vertical portion 42 from the third side 123, the risk of interference between the adapter 40 and the horizontal tongue 12 of the busbar 10 when the adapter 40 deforms due to external force can be reduced, which helps to improve the safety of the power bus group 100.

[0028] In some embodiments, the adapter 40 is configured as an integral part of the horizontal tongue 12 in the bus 10. Exemplarily, the adapter 40 is formed by stamping and bending the bus 10. This eliminates the need for attaching the adapter 40 to the horizontal tongue 12 in the bus 10, thus improving the assembly efficiency of the power bus assembly 100.

[0029] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
