Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector technology, and in particular to a bus module. Background Technology
[0002] In servers, the bus plays a crucial role in efficiently and with low loss transmitting electrical energy from the power module to high-power core components such as the CPU and GPU. Traditional bus designs typically employ a structure where positive and negative buses are either completely overlapping or completely staggered.
[0003] Since a certain distance needs to be maintained between the output terminals of the two buses, complete overlap of the positive and negative buses would waste materials and increase production costs. On the other hand, if the overlap ratio of the positive and negative buses is too low, the contact surface of the adhesive isolation material between the positive and negative buses will be insufficient, making them prone to separation and affecting the structural stability of the entire bus module. Utility Model Content
[0004] The main objective of this invention is to propose a bus module that aims to reduce production costs while ensuring the structural stability of the bus module.
[0005] To achieve the above objectives, the bus module proposed in this utility model includes:
[0006] Upper busbar, the upper busbar including a first horizontal plate;
[0007] A lower busbar panel, wherein the upper busbar panel and the lower busbar panel are stacked in a staggered manner, and the lower busbar panel includes a second horizontal plate parallel to the first horizontal plate; and
[0008] An insulating layer is sandwiched and bonded between the first horizontal plate and the second horizontal plate;
[0009] The length direction of the upper busbar is defined as the first direction, the total length of the upper busbar and the lower busbar stacked together along the first direction is L1, the length of the area where the upper busbar and the lower busbar are stacked together along the first direction is L2, and the length of the insulating layer along the first direction is L3; wherein, 0.5L1≤L2≤0.8L1, L2≤L3.
[0010] In one embodiment, the upper busbar plate has a first rear tongue that extends in a direction perpendicular to the first direction.
[0011] In one embodiment, the first rear tongue is located at one end of the upper busbar plate away from the lower busbar plate along the first direction.
[0012] In one embodiment, the first rear tongue has a plurality of first threaded holes for threaded connection with the connector assembly.
[0013] In one embodiment, the lower busbar plate has a second rear tongue protruding from one end away from the upper busbar plate along the first direction. The second rear tongue extends in a direction perpendicular to the first direction and is disposed on the same side as the first rear tongue.
[0014] In one embodiment, the second rear tongue has a plurality of second threaded holes for threaded connection with the connector assembly.
[0015] In one embodiment, the lower busbar plate is further provided with a plurality of front tongues, each of which extends in a direction perpendicular to the first direction.
[0016] In one embodiment, the second rear tongue and each of the front tongues are disposed on both sides of the lower busbar plate opposite to the second horizontal plate.
[0017] In one embodiment, the bus module further includes at least two terminals, each of which is located on the side of the upper bus plate away from the insulating layer.
[0018] In one embodiment, the bus module further includes an insulating coating disposed on the outer peripheral wall of the upper bus plate and the outer peripheral wall of the lower bus plate.
[0019] In the technical solution of this utility model, the bus module includes an upper bus plate, a lower bus plate, and an insulating layer. The upper bus plate includes a first horizontal plate. The upper bus plate and the lower bus plate are stacked in a staggered manner. The lower bus plate includes a second horizontal plate parallel to the first horizontal plate. The insulating layer is sandwiched and bonded between the first horizontal plate and the second horizontal plate. The length direction of the upper bus plate is defined as the first direction. The total length of the upper bus plate and the lower bus plate after stacking along the first direction is L1. The length of the stacked area of the upper bus plate and the lower bus plate along the first direction is L2. The length of the insulating layer along the first direction is L3. Wherein, 0.5L1≤L2≤0.8L1, L2≤L3. In the technical solution of this utility model, the upper busbar and the lower busbar can be regarded as the positive busbar and the negative busbar in the background art. By controlling the overlap ratio of the upper busbar and the lower busbar to be maintained between 50% and 80%, the bonding effect of the insulation layer is ensured to be stable while reducing the overlap ratio of the upper busbar and the lower busbar. This can prevent the insufficient structural stability of the busbar module due to insufficient adhesion of the insulation layer caused by the excessive overlap length of the upper busbar and the lower busbar, and can also avoid excessive overlap causing redundant material consumption, thereby achieving a balance between the structural stability and economy of the busbar module.

[0030] To address the aforementioned problems, this utility model proposes a bus module 1000. Figure 1 , Figure 2 as well as Figure 3 A schematic diagram of the structure of an embodiment provided by this utility model.
[0031] Please see Figure 1 , Figure 2 as well as Figure 3 This utility model proposes a busbar module 1000 including an upper busbar plate 1, a lower busbar plate 2, and an insulating layer 3. The upper busbar plate 1 includes a first horizontal plate 11. The upper busbar plate 1 and the lower busbar plate 2 are stacked in a staggered manner. The lower busbar plate 2 includes a second horizontal plate 21 parallel to the first horizontal plate 11. The insulating layer 3 is sandwiched and bonded between the first horizontal plate 11 and the second horizontal plate 21. The length direction of the upper busbar plate 1 is defined as the first direction. The total length of the upper busbar plate 1 and the lower busbar plate 2 after stacking along the first direction is L1. The length of the stacked area of the upper busbar plate 1 and the lower busbar plate 2 along the first direction is L2. The length of the insulating layer 3 along the first direction is L3. Wherein, 0.5L1≤L2≤0.8L1, L2≤L3.
[0032] In the technical solution of this utility model, by controlling the overlap ratio of the upper busbar 1 and the lower busbar 2 to be maintained between 50% and 80%, the bonding effect of the insulation layer 3 is ensured to be stable while reducing the overlap ratio of the upper busbar 1 and the lower busbar 2. This can prevent insufficient structural stability of the busbar module 1000 due to insufficient adhesion of the insulation layer 3 caused by excessive overlap length of the upper busbar 1 and the lower busbar 2, and can also avoid excessive overlap causing redundant material consumption, thereby achieving a balance between the structural stability and economy of the busbar module 1000.
[0033] Please see Figure 1 and Figure 2In one embodiment of the present invention, the upper busbar plate 1 is provided with a first rear tongue 12, which extends in a direction perpendicular to the first direction.
[0034] The first rear tongue 12 serves as an extension of the upper busbar plate 1. In specific implementation, the first rear tongue 12 can be integrally stamped with the first horizontal plate 11, and the thickness of the first rear tongue 12 is consistent with that of the first horizontal plate 11. The extension length of the first rear tongue 12 can be set according to the installation requirements of the connector assembly.
[0035] By setting an extension structure perpendicular to the length direction in the non-overlapping area, the contact area between the bus module 1000 and the external connector is effectively increased. The vertical extension design of the first rear tongue 12 avoids the material waste caused by the traditional fully overlapping structure, while ensuring structural strength through directional extension.
[0036] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the first rear tongue 12 is disposed at the end of the upper busbar plate 1 away from the lower busbar plate 2 along the first direction.
[0037] By positioning the first rear tongue 12 at the far end of the upper busbar 1, the spatial distance between the rear tongue and the lower busbar 2 can be effectively increased. This arrangement facilitates the installation of the connector assembly and avoids interference between the rear tongue and the lower structure. Simultaneously, the far-end rear tongue fully utilizes the longitudinal space of the upper busbar 1, optimizing the connection function without increasing the overall module size.
[0038] Understandably, the first rear tongue 12 has multiple first threaded holes 12a for threaded connection with the connector assembly. See also... Figure 1 and Figure 2 In one embodiment of the present invention, the first rear tongue 12 is provided with four first threaded holes 12a for threaded connection with the connector assembly.
[0039] A detachable mechanical connection between the bus module 1000 and the connector assembly is achieved by creating threaded holes in the extended first rear tongue 12. Compared to fixed connections such as welding, threaded connections facilitate on-site installation and maintenance, while the multi-hole distribution design effectively disperses connection stress. This structure solves the problem of complex assembly processes in traditional bus and connector assembly, improving modular assembly efficiency while ensuring conductivity.
[0040] Please see Figure 2In one embodiment of the present invention, the lower busbar plate 2 is provided with a second rear tongue 22 at one end away from the upper busbar plate 1 along the first direction. The second rear tongue 22 extends in a direction perpendicular to the first direction and is disposed on the same side as the first rear tongue 12.
[0041] Specifically, the second rear tongue 22 is a structural component symmetrically arranged with the first rear tongue 12, both extending along a direction perpendicular to the length of the busbar (the first direction). The second rear tongue 22 can be integrally formed with the lower busbar plate 2 by a stamping process; the thickness of the second rear tongue 22 is consistent with that of the lower busbar plate 2. The second rear tongue 22 and the first rear tongue 12 are positioned on the same side, ensuring that the two connecting surfaces are on the same side of the module, facilitating subsequent assembly operations.
[0042] By setting symmetrical rear tongue structures on the same side of the upper and lower busbars 2, a centralized arrangement of double-sided connection points is achieved. Compared with existing technologies, this avoids material waste caused by completely overlapping structures and ensures structural stability through symmetrical design on the same side.
[0043] Understandably, the second rear tongue 22 has multiple second threaded holes 22a for threaded connection with the connector assembly. See also... Figure 2 In one embodiment of the present invention, the second rear tongue 22 is provided with five second threaded holes 22a for threaded connection with the connector assembly.
[0044] By setting a second rear tongue 22 with a threaded hole in the lower busbar plate 2, the problem of the lower plate connection end not being securely fixed in the traditional busbar module 1000 is solved; the threaded connection method is easier to disassemble and repair than welding, and can be compatible with a variety of connectors through standardized thread specifications.
[0045] Understandably, the lower busbar plate 2 also has multiple protruding front tongues 23, each front tongue 23 extending in a direction perpendicular to the first direction. Please refer to... Figure 2 and Figure 3 In one embodiment of the present invention, the lower busbar plate 2 is further provided with two front tongues 23, each front tongue 23 extending in a direction perpendicular to the first direction.
[0046] Specifically, the front tongue 23 refers to a protruding structure extending outward from the main body of the lower busbar 2, with its extension direction perpendicular to the length direction of the busbar. The front tongue 23 can be configured as multiple independent protrusions arranged at equal intervals; as a preferred embodiment, the front tongue 23 and the second horizontal plate 21 are manufactured using an integral molding process to ensure structural strength and conductivity.
[0047] By providing two front tongues 23 on the lower busbar 2, more connection points can be provided, facilitating electrical connection with external devices. Compared with existing technologies, this design maintains the overall structural stability of the busbar module 1000 while improving the flexibility and convenience of connections. The extension direction of the front tongues 23 is consistent with that of the rear tongues, which helps simplify the manufacturing process while ensuring the rationality of the current transmission path.
[0048] Please see Figure 2 and Figure 3 In one embodiment of the present invention, the second rear tongue 22 and each front tongue 23 are disposed on both sides of the lower busbar plate 2 relative to the second horizontal plate 21.
[0049] The second rear tongue 22 and each of the front tongues 23 are spatially positioned on opposite sides of the second horizontal plate 21. The second rear tongue 22 is used for fixed connection with the connector assembly, while the front tongues 23 are used for connection with other electrical components.
[0050] The symmetrical distribution of the front tongue 23 and the second rear tongue 22 on both sides of the second horizontal plate 21 helps maintain the stress balance of the lower busbar plate 2. By symmetrically arranging the connecting structures on both sides of the lower busbar plate 2, the problem of mechanical stress concentration caused by single-sided connections in traditional designs is effectively improved. Since the connection points are distributed on both sides of the plate, they can form mutually canceling moments when subjected to external tensile forces, thereby improving the stability of the overall structure. Compared with the prior art, this layout ensures a sufficient number of connection interfaces while avoiding the risk of structural deformation caused by excessive concentration of connection points.
[0051] Please see Figure 1 In one embodiment of the present invention, the bus module 1000 further includes at least two terminals 4, each terminal 4 being located on the side of the upper bus plate 1 away from the insulating layer 3.
[0052] Terminal 4 is an interface component for connecting external wires and can be made of copper or aluminum. In specific implementations, terminal 4 can be electrically connected to the upper busbar 1 by welding or bolting. As a preferred embodiment, terminal 4 can be configured as a cylindrical boss structure with a threaded hole at the top to accommodate a standard cable connector. Furthermore, the arrangement of terminal 4 on the upper busbar 1 can be designed according to actual circuit requirements, such as equidistant arrangement along a first direction or grouped arrangement.
[0053] By setting the terminal blocks 4 on the opposite side of the insulation layer 3, the current multi-path distribution function is realized. Specifically, the terminal blocks 4 are directly integrated into the upper bus board 1, avoiding the problem of needing additional adapter components in traditional designs, which simplifies the assembly process and reduces contact resistance. Compared with the traditional bus structure mentioned in the background art, this design, while ensuring structural stability, can flexibly adapt to the circuit connection requirements of different power levels through the modular arrangement of the terminal blocks 4, effectively solving the technical problem of insufficient scalability of bus systems.
[0054] It should be noted that port 4 is not limited to Figure 1 , Figure 2 as well as Figure 3 As shown in the figure, the terminal 4 can be changed to extend from the side wall of the upper busbar 1 in the form of the front tongue 23, or it can be changed to other shapes that do not affect the wiring function, which will not be listed here.
[0055] In one embodiment of the present invention, the bus module 1000 further includes an insulating coating, which is disposed on the outer peripheral wall of the upper bus plate 1 and the outer peripheral wall of the lower bus plate 2.
[0056] Specifically, the insulating coating can be made of insulating materials such as epoxy resin, polyurethane, or silicone rubber, and is applied to the outer surface of the busbar through a spraying process. The insulating coating can extend to cover the exposed metal parts of the terminal block 4, but it is necessary to ensure that the connection functional areas of the first rear tongue 12, the second rear tongue 22, and each front tongue 23 are not sprayed with the insulating coating.
[0057] By applying an insulating coating to the outer periphery of the busbar, the problem of short circuits or leakage on exposed metal surfaces in traditional designs is effectively solved. This coating not only provides reliable surface insulation protection but also prevents metal oxidation and corrosion. Compared to existing technologies, this design eliminates the need for additional insulating partitions or sleeves, simplifying the assembly process while maintaining the overall compactness of the module.
[0058] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
