[0047] Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals are used in the drawings and the description to represent the same or similar parts.

[0048] Figure 1 It is a schematic diagram of a bus device according to an embodiment of the utility model being arranged in an electronic device. Figure 2 yes Figure 1 Please refer to the enlarged schematic diagram of the bus device. Figure 1 and Figure 2 The electronic device 10 of this embodiment is, for example, a cabinet, which can be used to accommodate electronic devices such as a power supply unit 20 and a server unit, but the electronic devices that can be accommodated in the electronic device 10 are not limited thereto.

[0049] The power supply unit 20 of the present embodiment is, for example, a power shelf, which is used to provide power. Figure 1 Several power supply units 20 are schematically shown, but the number and placement of the power supply units 20 are not limited thereto. The bus device 100 is disposed on the back side S1 of the chassis, and is adapted to electrically connect the power supply units 20 in the electronic device 10, so as to transmit the power of the power supply unit 20 to an electronic device (not shown) requiring power through the bus device 100.

[0050] In detail, the bus device 100 includes a housing 110, a plug assembly 120 ( Figure 2 ), at least one shunt component 130 and two conductive extensions 140a, 140b. The plug component 120 is disposed in the housing 110 and includes two plug parts 122a, 122b ( Figure 2 The plug-in parts 122a and 122b are suitable for plugging into the power supply unit 20 (for example, plugging into the electrical interface on the back side of the power supply unit 20) to obtain direct current from the power supply unit 20. In addition, the plug-in parts 122a and 122b are respectively positive and negative poles, so they do not contact each other to avoid short circuit.

[0051] Figure 3A yes Figure 1 Exploded view of the bus device. Figure 3B yes Figure 2 Please refer to the partial cross-sectional view of Figures 2 to 3B The shunt assembly 130 includes two conductive shunt members 132a and 132b, and the conductive shunt members 132a and 132b are respectively fixed on both sides of the plug assembly 120. In detail, the housing 110 has a notch O ( Figure 2 ), the notch O exposes a portion of the plug-in portions 122a, 122b, so that the conductive shunt members 132a, 132b can be respectively fixed to the portions of the plug-in portions 122a, 122b exposed from the notch O.

[0052] Furthermore, the two conductive shunt members 132a and 132b of the present embodiment are L-shaped. The conductive shunt member 132a includes a connecting portion 134a and a bending portion 136a connected in a bent manner, and the connecting portion 134a and the bending portion 136a are integrally formed. The connecting portion 134a is fixed to the corresponding plug-in portion 122a in the plug-in assembly 120, and the bending portion 136a is connected to the corresponding conductive extension member 140a.

[0053] Similarly, the conductive shunt 132b includes a connecting portion 134b and a bending portion 136b connected in a bent manner, and the connecting portion 134b and the bending portion 136b are integrally formed. The connecting portion 134b is fixed to the corresponding plug-in portion 122b in the plug-in assembly 120, and the bending portion 136b is connected to the corresponding conductive extension 140b.

[0054] On the other hand, the two conductive extensions 140a and 140b are, for example, flat plates and can be replaced and disposed on the two conductive shunts 132a and 132b respectively. The two conductive shunts 132a and 132b do not contact each other, and the two conductive extensions 140a and 140b do not contact each other to avoid short circuit.

[0055] When the power supply unit 20 ( Figure 1 After the current of the bus device 100 passes through the two plug-in parts 122a and 122b, the current is shunted to the two conductive extension parts 140a and 140b by the two conductive shunt parts 132a and 132b. The conductive extension parts 140a and 140b can further connect to the two conductive connecting parts 150a and 150b respectively. Figure 3A ) to transmit current to the electronic device that needs electricity through the conductive connecting members 150a, 150b, wherein the conductive connecting members 150a, 150b need to be staggered to avoid contact to prevent short circuit. The conductive connecting members 150a, 150b are, for example, copper bars formed by splicing, but the types of the conductive connecting members 150a, 150b are not limited to this.

[0056] The specifications of general bus devices (such as the Orv3 48V bus device in the Open Compute Project) are standardized, with a fixed current load, and can only use a limited current. It cannot be further expanded according to actual needs, and is extremely limited in use.

[0057] In contrast, the bus device 100 of the present embodiment adopts a shunt design, and the conductive shunt members 132a and 132b shunt the current introduced by the plug-in parts 122a and 122b to the conductive extension members 140a and 140b. Since the conductive extension members 140a and 140b configured on the conductive shunt members 132a and 132b can be replaced, the current resistance of the bus device 100 can be changed by replacing different conductive extension members 140a or 140b without changing the inherent power supply unit 20 or its electrical interface, thereby providing the bus device 100 with excellent expandability and bringing more flexibility in use.

[0058] In this embodiment, the connecting parts 134a and 134b are fixed to the plug-in parts 122a and 122b by screws or bolts, and the conductive extensions 140a and 140b are fixed to the conductive shunts 132a and 132b by screws or bolts. When the current resistance of the bus device 100 needs to be changed, the original conductive extensions 140a and 140b can be replaced with conductive extensions with different current resistance by simply loosening the screws or bolts, which is very convenient in use.

[0059] In addition, the material of the plug assembly 120 , the material of the conductive shunt members 132 a , 132 b , and the material of the conductive extension members 140 a , 140 b are copper, which is beneficial to power transmission.

[0060] In addition, at least one flow dividing component 130 of the present embodiment includes a plurality of flow dividing components 130 ( Figure 3A The conductive shunt members 132a and 132b of each shunt assembly 130 are respectively disposed on the conductive extension members 140a and 140b as described above. The number of shunt assemblies 130 can be determined according to design requirements, and the present invention does not impose any limitation thereto.

[0061] Figure 4 It is a partially enlarged schematic diagram of a bus device according to another embodiment of the utility model. Figure 5 yes Figure 4 Please refer to the partial cross-sectional view of Figure 4 and Figure 5 , this embodiment and Figures 1 to 3B The main difference of the illustrated embodiment is that in the bus device 100c, the lengths of the connecting portions 134c, 134d of the two conductive shunt members 132c, 132d of the shunt component 130c in the thickness direction D1 of the conductive extension members 140c, 140d are different from each other.

[0062] by Figure 5For example, the length L1 of the connection portion 134c is less than the length L2 of the connection portion 134d. Since a space is generated between the connection portion 134c and the connection portion 134d in the thickness direction D1, the conductive shunt member 132c can allow for the configuration of a thicker conductive extension member 140c (the thickness T1 of the conductive extension member 140c in this embodiment is greater than the thickness T2 of the conductive extension member 140d) without causing the conductive connecting members 150c and 150d connected to the conductive extension members 140c and 140d to contact each other and short-circuit. In other words, the design of this embodiment can facilitate the configuration of conductive extension members 140c and 140d of different thicknesses on the conductive shunt members 132c and 132d.

[0063] Of course, the thickness T1 of the conductive extension 140c may also be smaller than the thickness T2 of the conductive extension 140d. The thicknesses T1 and T2 may be determined by the lengths L1 and L2 of the connecting portions 134c and 134d.

[0064] When the power supply unit 20 ( Figure 1 ) enters the bus device 100c through the two plug-in parts 122a, 122b, and then the current is diverted to the two conductive extension parts 140c, 140d by the two conductive shunt parts 132c, 132d. The conductive extension parts 140c, 140d can be connected to the two conductive connecting parts 150c, 150d respectively to transmit the current to the electronic device that needs electricity through the conductive connecting parts 150c, 150d.

[0065] Since the conductive extension members 140c and 140d disposed on the conductive shunt members 132c and 132d are replaceable, there is no need to change the inherent power supply unit 20 or its electrical interface. The current carrying capacity of the bus device 100c can be changed by replacing different conductive extension members 140c or 140d, thereby providing the bus device 100c with excellent expandability and bringing more flexibility in use.

[0066] Figure 6 It is a schematic diagram of a bus device according to another embodiment of the utility model being arranged in an electronic device. Figure 7 yes Figure 6 A partial perspective cutaway view of a bus device. Please refer to Figure 6 and Figure 7 , this embodiment and Figures 1 to 3B The main difference of the illustrated embodiment is that two conductive extensions 140e, 140f are disposed on the side S2 of the electronic device 10e, which helps to save space.

[0067] In detail, Figure 7 As shown, the bending portion 136e of this embodiment includes a first bending sub-portion 1361e and a second bending sub-portion 1362e which are connected to each other in a bending manner.

[0068] The first bending sub-portion 1361e is connected between the connecting portion 134e and the second bending sub-portion 1362e, and the second bending sub-portion 1362e is connected to the corresponding conductive extension 140e. The plane where the first bending sub-portion 1361e is located is orthogonal to the plane where the corresponding second bending sub-portion 1362e is located. The connecting portion 134e, the first bending sub-portion 1361e and the second bending sub-portion 1362e are integrally formed.

[0069] Similarly, the bending portion 136f of this embodiment includes a first bending sub-portion 1361f and a second bending sub-portion 1362f connected to each other in a bending manner.

[0070] The first bending sub-portion 1361f is connected between the connecting portion 134f and the second bending sub-portion 1362f, and the second bending sub-portion 1362f is connected to the corresponding conductive extension 140f. The plane where the first bending sub-portion 1361f is located is orthogonal to the plane where the corresponding second bending sub-portion 1362f is located. The connecting portion 134f, the first bending sub-portion 1361f and the second bending sub-portion 1362f are formed in one piece. The conductive extensions 140e and 140f are parallel to the second bending sub-portions 1362e and 1362f.

[0071] On the other hand, the conductive extension member 140f in this embodiment is superimposed on the conductive extension member 140e. Since the conductive extension member 140f located outside the bus device 100e has an opening P, a portion of the second bent sub-portion 1362e located outside the bus device 100e can pass through the opening P and smoothly connect to the conductive extension member 140e located inside the bus device 100e. In addition, the conductive extension members 140e and 140f do not contact each other to avoid short circuit.

[0072] It is worth noting that the conductive shunts 132e and 132f of this embodiment are bent twice. Taking the conductive shunt 132e as an example, the connecting portion 134e of the conductive shunt 132e extends along the extension direction D2, and is bent along the extension direction D3 perpendicular to the extension direction D2 to form a first bending sub-portion 1361e, and the first bending sub-portion 1361e is further bent along the extension direction D4 perpendicular to the extension direction D3 to form a second bending sub-portion 1362e, wherein the extension direction D4 is parallel to the extension direction D2. The conductive shunt 132f is also bent in a similar manner to the above-mentioned conductive shunt 132f, which will not be described in detail here.

[0073] Thus, the plane where the first bending sub-portions 1361e and 1361f are located (parallel to Figure 6 The back side S1 of the electronic device 10e in FIG. 1 is perpendicular to the plane where the conductive extensions 140e and 140f are located (parallel to Figure 6The side S2 of the electronic device 10e in the figure) allows the conductive extension members 140e and 140f to be disposed on the side S2 of the electronic device 10e, and are not limited to being disposed on the back S1 of the electronic device 10e. This helps save space behind the electronic device 10e and makes space utilization more flexible.

[0074] When the power supply unit 20 ( Figure 6 ) enters the bus device 100e through the two plug-in parts 122a, 122b, and the current is diverted by the two conductive shunt members 132e, 132f (that is, passing through the connecting part 134e, the first bending sub-portion 1361e and the second bending sub-portion 1362e, and the connecting part 134f, the first bending sub-portion 1361f and the second bending sub-portion 1362f respectively) to the two conductive extension members 140e, 140f, so as to transmit the current to the electronic device requiring electricity through the conductive connecting members 150e, 150f.

[0075] Since the conductive extension parts 140e and 140f arranged on the conductive shunt parts 132e and 132f can be replaced, there is no need to change the inherent power supply unit 20 or its electrical interface. The current carrying capacity of the bus device 100e can be changed by replacing different conductive extension parts 140e or 140f, thereby providing the bus device 100e with excellent expandability and bringing more flexibility in use.

[0076] In addition, the bus device 100e of this embodiment further includes an insulating sheet 160. The insulating sheet 160 is made of resin, for example, and is attached between the bending portions 136e and 136f of the conductive shunt members 132e and 132f, that is, between the first bending sub-portion 1361e and the second bending sub-portion 1362e and between the first bending sub-portion 1361f and the second bending sub-portion 1362f, by, for example, bonding, to prevent the conductive shunt members 132e and 132f from contacting each other and causing a short circuit.

[0077] In addition, at least one flow dividing component 130e of this embodiment is a plurality of ( Figure 6 The conductive shunt components 132e and 132f of each shunt component 130e are respectively disposed on two conductive extension components 140e and 140f. The number of shunt components 130e can be determined according to design requirements, and the present invention does not impose any restrictions on this. In addition, Figure 6 A plurality of power supply units 20 are schematically shown, but the number and positions of the power supply units 20 are not limited thereto.

[0078] In summary, in the bus device of the utility model, the two conductive shunt members of the shunt assembly are respectively fixed on both sides of the plug assembly, and the two conductive extension members are replaceably configured on the two conductive shunt members. When the bus device is plugged into an external power supply unit through the plug assembly, the two conductive shunt members can further distribute the current from the power supply unit. In addition, the conductive shunt member is configured with a replaceable conductive extension member, so there is no need to change the inherent power supply unit or its electrical interface, and the current resistance of the bus device can be adjusted by replacing different conductive extension members, thereby providing good expandability and bringing more flexibility in use.

[0079] In addition, the two conductive shunts may further include two connecting portions of different lengths to facilitate the configuration of conductive extensions of different thicknesses. In addition, the two conductive shunts may further have a secondary bending configuration to make the positions of the two conductive extensions more flexible and help save space.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
