[0027] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.
[0028] In related technologies, busbar structures typically include an outer shell, multiple copper busbars, and plastic insulation components. The plastic insulation components are one-time extrusion molded structures. The outer shell, copper busbars, and plastic insulation components are all elongated structures. The copper busbars are inserted into the plastic insulation components, and the plastic insulation components are inserted into the outer shell. The copper busbars achieve the effect of conductive connection or power supply connection to external electrical equipment.
[0029] When assembling the busbar structure in the related technology, it is necessary to insert the plastic insulating component into the housing 1 along the length direction of the housing, and insert the copper busbar into the insulating component along the length direction of the housing.
[0030] On the one hand, the assembly steps of the existing busbar structure are cumbersome, and the plastic insulation components and copper busbars are easily bent and damaged during the insertion process, and require a large environmental space. On the other hand, in order to ensure the smooth insertion of the plastic insulation components and copper busbars, a large assembly gap needs to be reserved between the plastic insulation components and the outer shell, as well as between the copper busbars and the plastic insulation components, which hinders the heat generated by the copper busbars from being conducted to the outer shell, resulting in an increase in the overall thermal resistance of the busbar structure and an excessively high temperature rise.
[0031] To address the technical problems existing in the aforementioned busbar trunking structure, this application provides a busbar trunking structure and its assembly method, which can effectively simplify the assembly steps and reduce temperature rise. The following is a detailed description... Figures 1 to 5 The busbar trunking structure and its assembly method according to the embodiments of this application will be described in detail.
[0032] It should be noted that the first direction X, the second direction Y, and the third direction Z described in the embodiments of this application are only for better illustrating the specific structure of this application in conjunction with the accompanying drawings, and this application is not limited thereto.
[0033] The first direction X, the second direction Y, and the third direction Z form angles with each other. Optionally, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other. Optionally, after the busbar structure is assembled, the first direction X is the width direction of the busbar structure, the second direction Y is the height direction of the busbar structure, and the third direction Z is the length direction of the busbar structure.
[0034] like Figure 1 As shown in the figure, this application embodiment provides a busbar structure, wherein the busbar structure includes a housing 1, an insulation layer 2, and a connecting bar 3.
[0035] The housing 1 is provided with at least one mounting groove 11 to accommodate the positioning connection row 3.
[0036] The insulating layer 2 is applied to the inner surface of the mounting groove 11, and the insulation between the connecting bar 3 and the housing 1 is achieved by setting the insulating layer 2.
[0037] The width of the mounting groove 11 is greater than or equal to the thickness of the connecting strip 3, so that the connecting strip 3 can enter or exit the mounting groove 11 from the opening of the mounting groove 11 along the depth direction of the mounting groove 11. During the assembly of the busbar structure, the connecting strip 3 is pressed into the mounting groove 11 from the opening of the mounting groove 11 along its depth direction, so that the connecting strip 3 can be assembled from the opening of the mounting groove 11 along the depth direction of the mounting groove 11, eliminating the step of assembling along the length direction in the prior art.
[0038] The housing 1 is made of a material with good rigidity to ensure its structural strength, and the connecting bar 3 is made of a material with good conductivity to ensure its electrical connection function. By setting the insulating layer 2, insulation between the connecting bar 3 and the housing 1 can be achieved, so that the connecting bar 3 can safely transmit electrical energy.
[0039] Optionally, the shell 1 has an open plate structure, and the mounting groove 11 is formed on one side surface of the plate structure.
[0040] Optionally, the housing 1 is a cylindrical structure formed by multiple plates enclosing a closed space, and the mounting groove 11 is formed on the inner surface of the cylindrical structure.
[0041] Optionally, the housing 1 is a groove-shaped structure formed by multiple plates enclosing a semi-enclosed space, and the mounting groove 11 is formed on the inner surface of the groove-shaped structure.
[0042] Optionally, along the depth direction of the mounting groove 11, the depth of the mounting groove 11 is greater than the size of the connecting strip 3, and along the width direction of the mounting groove 11, the width of the mounting groove 11 is greater than the size of the connecting strip 3, so as to provide assembly space for the insulating layer 2 and ensure the smooth assembly of the connecting strip 3 in the mounting groove 11.
[0043] Optionally, the insulating layer 2 is an insulating film. The insulating film is attached to the inner surface of the housing 1 and covers the inner surface of each mounting groove 11. The thickness of the insulating film is less than or equal to 0.8 mm. While ensuring the insulation effect, it effectively shortens the heat transfer path between the connecting bar 3 and the housing 1 and improves the heat dissipation effect.
[0044] The insulating layer 2 of the insulating film has a soft structure. When it covers the inner surface of the mounting groove 11, it can fit tightly with the inner surface of the mounting groove 11 with a very small gap between them. After the connecting strip 3 is assembled on the surface of the insulating layer 2, it can also fit tightly with the surface of the connecting strip 3 with a very small overall gap. This effectively reduces the overall thermal resistance of the busbar structure and thus effectively reduces the temperature rise of the busbar structure.
[0045] Specifically, the insulating film is a PET (Polyethylene terephthalate) film, and the thickness of a single layer of the insulating film is 0.15~0.25mm. Within this thickness range, the insulating film is relatively thin, thereby reducing the overall thickness. This results in lower thermal resistance on the inner surface of the mounting groove 11 connecting the connector 3 to the housing 1, thus achieving higher heat dissipation efficiency.
[0046] Specifically, each mounting groove 11 is provided with two layers of insulating film, which are laid in layers, and the total thickness of the two insulating films is 0.4~0.6mm. Within this thickness range, good insulation effect can be achieved.
[0047] Optionally, along the width direction of the mounting groove 11, the width of the mounting groove 11 is 0.2 mm to 0.4 mm greater than the size of the connecting strip 3, and the thickness of the insulation layer 2 is 0.4 mm to 0.6 mm. After the insulation layer 2 is installed, the connecting strip 3 is installed inside the mounting groove 11 in an interference fit manner to ensure its installation reliability.
[0048] Optionally, along the depth direction of the mounting groove 11, the depth of the mounting groove 11 is 0.1 mm to 0.2 mm greater than the sum of the dimensions of the connecting strip 3 and the insulating layer 2, so as to ensure that when the connecting strip 3 is installed inside the mounting groove 11, the connecting strip 3 is completely embedded inside the mounting groove 11 and has a certain distance between it and the groove opening, thereby reducing the occurrence of electric shock or short circuit due to accidental contact with the connecting strip 3.
[0049] like Figure 2 As shown, in some optional embodiments, the busbar trunking structure includes a housing 1, which has an insertion space 10. Multiple mounting slots 11 are spaced apart on the inner wall of the housing 1, and the opening of each mounting slot 11 communicates with the insertion space 10. The housing 1 has a groove-shaped structure, and the insertion space 10 is a semi-enclosed space. When assembling the connecting strip 3, the connecting strip 3 is inserted into the housing 1 from the opening of the groove-shaped structure along the depth direction of the groove-shaped structure. This avoids the assembly step of the connecting strip 3 passing through the length direction of the housing 1 in related technologies, simplifying the assembly steps and effectively reducing the bending deformation of the connecting strip 3 under stress, ensuring product quality. Simultaneously, the overall assembly distance is shorter, allowing the connecting strip 3 to be smoothly embedded into the mounting slot 11 without occupying a large assembly space. Furthermore, it enables close contact between the connecting strip 3, the insulation layer 2, and the housing 1, effectively reducing the overall thermal resistance of the busbar trunking structure and thus effectively reducing the temperature rise of the busbar trunking structure.
[0050] In the embodiments of this application, the busbar structure can be used as an electrical transmission device on its own, or multiple busbar structures can be connected end to end in sequence to form an electrical transmission device to extend its transmission path length and have good assembly flexibility.
[0051] like Figures 2 to 4 As shown in the embodiment of this application, the busbar structure includes a housing 1 comprising two side plates 13 and a top plate 14.
[0052] The two side plates 13 are arranged opposite each other at intervals along the first direction X. At least one mounting groove 11 is recessed on the surface of each side plate 13 facing the other side plate 13. Each mounting groove 11 can accommodate a connecting row 3. The number of mounting grooves 11 and connecting rows 3 can be adjusted according to actual electrical transmission requirements.
[0053] The top plate 14 is located on one side of the two side plates 13 along the second direction Y. The two side plates 13 are detachably connected to the top plate 14. The two side plates 13 and the top plate 14 enclose and form an insertion space 10. The slots of each mounting groove 11 are connected to the insertion space 10.
[0054] Specifically, the two side plates 13 and the top plate 14 roughly enclose a U-shaped structure, which is a semi-enclosed space with a groove-like structure. When in use, the opening of the U-shaped structure can be flexibly adjusted to face any direction according to the direction of the electrical device and the power supply device.
[0055] When assembling the connecting strip 3, the two side plates 13 and the top plate 14 can be separated. The side plates 13 are laid flat on the operating surface, and the connecting strip 3 is placed on the side plates 13 and positioned opposite the mounting groove 11. Then, a force is applied from top to bottom to press the connecting strip 3 into the mounting groove 11. After the connecting strip 3 in each mounting groove 11 is installed, the two side plates 13 and the top plate 14 are assembled. This can further reduce the assembly difficulty of the connecting strip 3, optimize the stress on the connecting strip 3 during the installation process, and improve the assembly quality of the busbar structure.
[0056] In some optional embodiments, each of the two side plates 13 is provided with a plurality of mounting slots 11 on the side facing the other side plate 13. The plurality of mounting slots 11 on each side plate 13 are spaced apart along the second direction Y. During assembly, a connecting row 3 can be installed in each mounting slot 11, so that the busbar structure includes a plurality of connecting rows 3, thereby improving the current carrying capacity of the busbar structure for high current application scenarios.
[0057] The mounting slots 11 on the two side plates 13 are set one-to-one along the first direction X, which can realize the symmetrical arrangement of the connecting row 3, forming a balanced flow and uniform force on both sides of the busbar structure.
[0058] like Figures 2 to 4 As shown in the embodiment of this application, the busbar structure includes a housing 1 that further includes multiple limiting base plates 15. The multiple limiting base plates 15 are disposed on the other side of the two side plates 13 along the second direction Y. By setting multiple limiting base plates 15 to cooperate with the top plate 14 to connect the two side plates 13, the relative positions of the two side plates 13 can be effectively fixed and maintained, ensuring the overall structural stability of the housing 1.
[0059] Multiple limiting base plates 15 are spaced apart along the third direction Z. Each limiting base plate 15 is detachably connected to the two side plates 13. At least one side of the limiting base plate 15 along the third direction Z forms a plug interface 12 and / or the limiting base plate 15 is provided with a plug interface 12. The plug interface 12 is connected to the plugging space 10. The plug interface 12 allows the plug of the external electrical equipment to enter into the plugging space 10 and make an electrical connection with the connecting strip 3. Therefore, the limiting base plate 15 can also isolate the plugs of adjacent external electrical equipment, further improving the rationality and safety of the allocation of the installation position of the external electrical equipment.
[0060] Optionally, the number of limiting base plates 15 and the dimensions of the limiting base plates 15 along the third direction Z can be flexibly adjusted according to the dimensions of the housing 1 along the third direction Z, so as to ensure the limiting connection of the two side plates 13 and ensure the strength of the housing 1.
[0061] Optionally, the distance between two adjacent limiting base plates 15 can be flexibly adjusted according to the size of the electrical plug of the external electrical device or the assembly requirements of the power supply device, but this application is not limited thereto.
[0062] like Figure 4 As shown in the embodiment of this application, the bus trunking structure further includes a plurality of positioning members 4. The mounting groove 11 has a positioning groove 16 on at least one side along its width direction. Each positioning groove 16 is embedded with a positioning member 4. A part of the positioning member 4 extends out of the corresponding positioning groove 16, and along the depth direction of the mounting groove 11, a part of the projection of the positioning member 4 falls into the projection of the mounting groove 11.
[0063] The groove opening of the positioning groove 16 faces the same direction as the groove opening of the mounting groove 11, and the assembly of each connecting row 3 and each positioning component 4 can be completed sequentially without changing the state of the side plate 13.
[0064] By setting the positioning element 4, the connecting strip 3 located in the adjacent mounting slot 11 can be effectively limited, preventing the connecting strip 3 from moving relative to the mounting slot 11 and falling off the mounting slot 11, thus ensuring the reliable assembly of the connecting strip 3.
[0065] The mounting slots 11 and positioning slots 16 are arranged alternately to ensure that each mounting slot 11 has a positioning slot 16 and positioning element 4 on at least one side, thereby limiting the connection row 3 in each mounting slot 11.
[0066] Optionally, the positioning element 4 is made of insulating material to ensure that it has good insulation and protection effects.
[0067] Optionally, the positioning element 4 has good elasticity so that it can be installed in the corresponding positioning groove 16 with an interference fit, ensuring its assembly reliability.
[0068] Optionally, the positioning element 4 is made of materials such as rubber or silicone.
[0069] like Figure 4 As shown in the embodiment of this application, the bus trunking structure includes a positioning member 4 comprising an insertion part 41 and a stop part 42 connected to each other. The insertion part 41 is interference-fitted into the corresponding positioning groove 16, and the positioning member 4 and the positioning groove 16 are reliably assembled through the insertion part 41.
[0070] The stop part 42 is located outside the positioning groove 16. Along the depth direction of the mounting groove 11, part of the projection of the stop part 42 coincides with the projection of the adjacent mounting groove 11. The stop part 42 achieves the limiting effect of the positioning member 4 on the connecting row 3.
[0071] Optionally, along the depth direction of the mounting groove 11, when the depth of the mounting groove 11 is less than or equal to the size of the connecting row 3, the stop part 42 abuts against the connecting row 3 in the adjacent mounting groove 11 to ensure the limiting effect of the stop part 42 on the connecting row 3. At the same time, the positioning member 4 can provide insulation protection for the part of the connecting row 3 that protrudes from the mounting groove 11, thereby improving the safety of electrical transmission.
[0072] Optionally, the insertion part 41 and the stop part 42 are integrally formed to ensure structural strength and have the advantages of being easy to process.
[0073] like Figures 1 to 4 As shown in the embodiment of this application, the busbar structure has a connecting recess 31 for the insertion of the plug of an external electrical device, which increases the contact area between the plug of the external electrical device and the connecting recess 3, ensures the reliability of the electrical connection, and realizes stable power transmission.
[0074] Optionally, along the depth direction of the mounting groove 11, the projection of the stop portion 42 is offset from the projection of the connecting recess 31 to prevent the positioning member 4 from interfering with the insertion of the electrical plug of the external electrical device, and to ensure that the electrical plug of the external electrical device is smoothly engaged with the connecting recess 31.
[0075] In the busbar structure of this application embodiment, the two ends of the connecting bar 3 extend to the outside of the housing 1 to form connecting ends.
[0076] In this embodiment, when the connecting strip 3 needs to be connected to an external power supply device or other busbar trunking structures at its end, the external power supply device can be directly connected to the connecting end of this connecting strip 3, or the connecting ends of the connecting strips 3 of two busbar trunking structures can be directly connected. The connection end design improves the convenience of end connection, thereby enhancing the flexibility of busbar trunking structures in different power supply environments.
[0077] like Figures 1 to 4As shown in the embodiment of this application, the busbar structure has a plurality of heat dissipation fins 17 spaced apart on the outer surface of the housing 1.
[0078] Heat dissipation fins 17 are spaced apart on the outer surface of the housing 1. When the heat from the connecting bar 3 inside the housing 1 is transferred to the surface of the housing 1, the multiple heat dissipation fins 17 can transfer the internal heat to the outside, increase the heat dissipation area, and thus further improve the heat dissipation effect of the busbar structure.
[0079] Specifically, multiple heat dissipation fins 17 are spaced apart on the side of each side plate 13 facing away from the other side plate 13, and can be arranged corresponding to the connecting rows 3 on the two side plates 13, thereby reducing the heat transfer path between them and the connecting rows 3 and further improving heat dissipation efficiency.
[0080] like Figure 5 As shown in the figure, this application embodiment also provides an assembly method for a busbar trunking structure, wherein the assembly method for the busbar trunking structure is used to assemble the above-mentioned busbar trunking structure, such as... Figure 4 As shown, the assembly method of the busbar structure includes: S100. A housing 1 is provided, and at least one mounting groove 11 is machined on the housing 1. The mounting groove 11 is used to accommodate the positioning connecting strip 3. The width of the mounting groove 11 is greater than or equal to the thickness of the connecting strip 3, so that the connecting strip 3 can enter or exit the mounting groove 11 from the opening of the mounting groove 11 along the depth direction of the mounting groove 11. During the assembly of the busbar structure, the connecting strip 3 is pressed into the mounting groove 11 from the opening of the mounting groove 11 along its depth direction, so that the connecting strip 3 can be assembled from the opening of the mounting groove 11 along the depth direction of the mounting groove 11, eliminating the step of assembling along the length direction in the prior art.
[0081] S200. An insulating layer 2 is applied to the inner surface of the mounting groove 11; the insulating layer 2 achieves insulation between the connecting strip 3 and the housing 1. The insulating layer 2 is an insulating film, which is applied to the inner surface of the housing 1 and covers the inner surface of each mounting groove 11. The thickness of the insulating film is less than or equal to 0.8 mm, which effectively shortens the heat transfer path between the connecting strip 3 and the housing 1 while ensuring the insulation effect, thus improving the heat dissipation effect.
[0082] S300, Press the connecting strip 3 into the corresponding mounting groove 11 from the groove opening along the depth direction of the mounting groove 11, so that the connecting strip 3 and the insulating layer 2 are in contact.
[0083] Optionally, along the depth direction of the mounting groove 11, the depth of the mounting groove 11 is greater than the size of the connecting strip 3, and along the width direction of the mounting groove 11, the width of the mounting groove 11 is greater than the size of the connecting strip 3, so as to provide assembly space for the insulating layer 2 and ensure the smooth assembly of the connecting strip 3 in the mounting groove 11.
[0084] Optionally, along the depth direction of the mounting groove 11, the depth of the mounting groove 11 is 0.1 mm to 0.2 mm greater than the sum of the dimensions of the connecting strip 3 and the insulating layer 2, so as to ensure that when the connecting strip 3 is installed inside the mounting groove 11, the connecting strip 3 is completely embedded inside the mounting groove 11 and has a certain distance between it and the groove opening, thereby reducing the occurrence of electric shock or short circuit due to accidental contact with the connecting strip 3.
[0085] The assembly method of the busbar trunking structure provided in this application embodiment involves first covering the inner surface of the corresponding mounting groove 11 with the insulating layer 2, and then pressing the connecting strip 3 into the mounting groove 11 along the depth direction of the mounting groove 11 through the groove opening. With this assembly method, it is not necessary to pass the connecting strip 3 through the length direction of the shell 1, and the assembly steps are relatively simple. It can effectively reduce the bending deformation of the connecting strip 3, ensure product quality, and at the same time, the overall assembly distance is short. The connecting strip 3 can be smoothly embedded into the mounting groove 11 without occupying a large assembly space. It can also achieve a tight fit between the connecting strip 3, the insulating layer 2 and the shell 1, effectively reducing the overall thermal resistance of the busbar trunking structure, thereby effectively reducing the temperature rise of the busbar trunking structure.

An insulating layer 2 is provided inside the housing 1 so that the insulating layer 2 covers the inner surface of each mounting groove 11; S300, Press the connecting strip 3 into the corresponding mounting groove 11 from the groove opening of the corresponding mounting groove 11 so that the connecting strip 3 is in contact with the insulating layer 2.
[0087] In this embodiment, the processed housing 1 has a groove-shaped structure, and the insertion space 10 is a semi-enclosed space. When assembling the connecting strip 3, the connecting strip 3 is inserted into the housing 1 from the opening of the groove-shaped structure along the depth direction of the groove-shaped structure. This avoids the assembly step of the connecting strip 3 passing through the length direction of the housing 1 in related technologies, simplifies the assembly steps, effectively reduces the bending deformation of the connecting strip 3 under stress, ensures product quality, and at the same time, the overall assembly distance is shorter. The connecting strip 3 can be smoothly embedded into the mounting groove 11 without occupying a large assembly space. It can also achieve close contact between the connecting strip 3, the insulation layer 2 and the housing 1, effectively reducing the overall thermal resistance of the busbar structure, thereby effectively reducing the temperature rise of the busbar structure.

[0093] The shell 1 is split into two side plates 13 and a top plate 14, which can be processed separately, effectively reducing the processing difficulty.
[0094] Furthermore, when machining the mounting groove 11 for each top plate 14 or side plate 13, the top plate 14 and side plate 13 can be laid flat on the operating plane, which is conducive to the stability of the top plate 14 and side plate 13 and reduces the displacement of the top plate 14 and side plate 13 under force during the machining process.
[0095] The assembly method of the busbar trunking structure in this application embodiment includes covering and affixing an insulating layer 2 to the inner surface of the mounting groove 11, comprising: The side plate 13 is laid flat with the second side surface facing down, and the insulating layer 2 is attached to the first side surface so that the insulating layer 2 covers the inner surface of the mounting groove 11.
[0096] The method of laying the insulation layer 2 on the side panel 13 from top to bottom can effectively ensure the stability of the side panel 13, reduce the displacement of the side panel 13 under force, and ensure the bonding effect of the insulation layer 2.
[0097] The insulating layer 2 is a flexible insulating film that covers the entire area of the first side surface of the side plate 13, which can isolate the connecting row 3 from the side plate 13 to the greatest extent and ensure the insulation effect.
[0098] The insulation layer 2 is attached to the first side surface of the side plate 13 and can fit tightly against the inner surface of the mounting groove 11, minimizing the gap between them. After the connecting strip 3 is installed, the connecting strip 3 fits tightly against the insulation layer 2 in the mounting groove 11, minimizing the air gap in the heat transfer path and effectively reducing the overall thermal resistance of the busbar structure, thereby effectively reducing the temperature rise of the busbar structure.
[0099] The assembly method of the busbar trunking structure in this application embodiment includes pressing the connecting strip 3 into the corresponding mounting groove 11 from the groove opening of the mounting groove 11, so that the connecting strip 3 is in close contact with the insulation layer 2, comprising: With the side plate 13 laid flat with the second side surface facing down, the connecting strip 3 is pressed into the mounting groove 11 through the groove opening along the depth direction of the mounting groove 11 in an interference fit manner.

After the insulation layer 2 is installed, the connecting strip 3 is installed inside the mounting groove 11 in an interference fit manner to ensure its installation reliability.

A positioning element 4 is provided on at least one side of the mounting groove 11 along its width direction, and the connecting row 3 is confined in the corresponding mounting groove 11 by the positioning element 4.
[0102] Along the depth direction of the mounting groove 11, part of the projection of the positioning member 4 falls into the projection of the mounting groove 11, so as to block at the opening of the mounting groove 11, prevent the connecting strip 3 from moving relative to the mounting groove 11 and falling off the mounting groove 11, ensure the reliable assembly of the connecting strip 3, and stabilize the power transmission effect.
[0103] The assembly method of the busbar trunking structure according to the embodiments of this application includes providing a positioning member 4 on at least one side of the mounting groove 11 along its width direction, and using the positioning member 4 to confine the connecting bar 3 in the corresponding mounting groove 11, including: S410 After forming at least one mounting groove 11 on the first side surface of at least one side plate 13, a positioning groove 16 is formed on the first side surface at a position on at least one side of the mounting groove 11 along its width direction, such that the groove opening of the positioning groove 16 is oriented in the same direction as the groove opening of the mounting groove 11, so that the assembly of each connecting row 3 and each positioning member 4 can be completed sequentially without changing the state of the side plate 13.
[0104] The mounting slots 11 and positioning slots 16 are arranged alternately to ensure that each mounting slot 11 has a positioning slot 16 and positioning element 4 on at least one side, thereby limiting the connection row 3 in each mounting slot 11.
[0105] S420. A portion of the positioning member 4 is fixedly installed in the positioning groove 16 with an interference fit, so that the other portion of the positioning member 4 is located outside the positioning groove 16; and along the depth direction of the mounting groove 11, the portion of the positioning member 4 located outside the positioning groove 16 abuts against the connecting row 3 located inside the mounting groove 11 at the groove opening of the mounting groove 11.
[0106] Optionally, the positioning element 4 is made of insulating material to ensure that it has good insulation and protection effects.
[0107] Optionally, the positioning element 4 has good elasticity so that it can be installed in the corresponding positioning groove 16 with an interference fit, ensuring its assembly reliability.

The insertion part 41 is inserted into the corresponding positioning groove 16 with an interference fit, and the positioning member 4 and the positioning groove 16 are reliably assembled through the insertion part 41.
[0110] The stop part 42 is located outside the positioning groove 16. Along the depth direction of the mounting groove 11, part of the projection of the stop part 42 coincides with the projection of the adjacent mounting groove 11. The stop part 42 achieves the limiting effect of the positioning member 4 on the connecting row 3.
[0111] Optionally, along the depth direction of the mounting groove 11, when the depth of the mounting groove 11 is less than or equal to the size of the connecting row 3, the stop part 42 abuts against the connecting row 3 in the adjacent mounting groove 11 to ensure the limiting effect of the stop part 42 on the connecting row 3. At the same time, the positioning member 4 can provide insulation protection for the part of the connecting row 3 that protrudes from the mounting groove 11, thereby improving the safety of electrical transmission.
[0112] Optionally, the insertion part 41 and the stop part 42 are integrally formed to ensure structural strength and have the advantages of being easy to process.

The two side plates 13 and the top plate 14 are arranged to form an insertion space 10, and the mounting groove 11 is connected to the insertion space 10.
[0114] Specifically, the two side plates 13 and the top plate 14 roughly enclose a U-shaped structure, which is a semi-enclosed space with a groove-like structure. When in use, the opening of the U-shaped structure can be flexibly adjusted to face any direction according to the direction of the electrical device and the power supply device.

The side plates 13 are laid flat on the operating surface, and the connecting strip 3 is placed on the side plates 13 and positioned opposite the mounting groove 11. Then, a force is applied from top to bottom to press the connecting strip 3 into the mounting groove 11. After the connecting strip 3 in each mounting groove 11 is installed, the two side plates 13 and the top plate 14 are assembled. This can further reduce the assembly difficulty of the connecting strip 3, optimize the stress on the connecting strip 3 during the installation process, and improve the assembly quality of the busbar structure.

The plug interface 12 allows the plug of the external electrical equipment to enter into the plugging space 10 and make an electrical connection with the connecting strip 3. Therefore, the limiting base plate 15 can also isolate the plugs of adjacent external electrical equipment, further improving the rationality and safety of the allocation of the installation position of the external electrical equipment.
[0119] The assembly method of the busbar trunking structure of this application involves first covering the inner surface of the corresponding mounting groove 11 with the insulating layer 2, and then pressing the connecting strip 3 into the mounting groove 11 along the depth direction through the groove opening. With this assembly method, it is not necessary to pass the connecting strip 3 through the length direction of the shell 1, and the assembly steps are relatively simple. It can effectively reduce the bending deformation of the connecting strip 3, ensure product quality, and at the same time, the overall assembly distance is short. The connecting strip 3 can be smoothly embedded into the mounting groove 11 without occupying a large assembly space. It can also achieve a tight fit between the connecting strip 3, the insulating layer 2 and the shell 1, effectively reducing the overall thermal resistance of the busbar trunking structure, thereby effectively reducing the temperature rise of the busbar trunking structure.
