Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a controller for a vehicle and a vehicle. Background Technology

[0002] With the trend of all-in-one electric vehicles, the structure of current electric vehicle compressor controllers is becoming increasingly compact. Some compressor manufacturers use connectors with built-in copper busbars, directly soldering the connectors onto the circuit board. However, because connector manufacturers need to fix the copper busbars on the connector mold during production, the manufacturing cost is high, and unless a new mold is made, it is impossible to use other specifications of copper busbars, resulting in a relatively limited form. Other compressor manufacturers use a more traditional wire harness connection method, with one end inserted into a high-voltage connector and the other end locked in the circuit board with a cold-pressed terminal. However, due to the compact internal structure of the electric compressor controller, the cold-pressed terminal occupies a certain amount of space, and the terminal position can only be fixed manually during actual fixing, which cannot be automated and the fixing process is relatively troublesome.

[0003] Therefore, improving the ease of installation of the controller is a technical problem that urgently needs to be solved. Utility Model Content

[0004] This application provides a controller and vehicle for use in vehicles, which improves the ease of installation.

[0005] To achieve the above objectives, the main technical solutions adopted in this application include:

[0006] In a first aspect, embodiments of this application provide a controller for a vehicle, including a housing, a circuit board, and a connector: the housing has an internal accommodating space; the circuit board is disposed in the accommodating space, and the circuit board has solder holes that penetrate the circuit board along its thickness direction; the connector includes a connector body and a first wire harness disposed on the connector body, and along the length direction of the first wire harness, the first wire harness includes a first segment and a second segment disposed opposite to each other, the first segment being adapted to be electrically connected to a power source, and the second segment engaging with the solder holes and being electrically connected to the circuit board.

[0007] According to the vehicle controller proposed in the first aspect of this application, the first wire harness can be assembled with the circuit board without bending the first wire harness, which greatly reduces the space occupied by the first wire harness inside the controller. At the same time, the welding holes can provide clear guidance for the first wire harness. Assembly can be completed simply by aligning the second segment with the welding holes and inserting it. In addition, it is easy to adapt to different distances between the PCB board and the housing, which improves the ease of installation and assembly efficiency.

[0008] Optionally, along the thickness direction of the circuit board, the circuit board has a first side and a second side disposed opposite to each other, the first side being closer to the connector body than the second side, and the second segment passing through the solder hole and protruding from the second side.

[0009] In the above scheme, the second section passes through the welding hole and passes through the first side and the second side in sequence, which reduces the bending stress caused by the bending of the wire harness, reduces the probability of insulation layer damage and wire breakage, effectively avoids early failure of the wire harness caused by bending, and improves the overall reliability of the controller.

[0010] Optionally, the length of the second segment protruding from the second side is not less than 2mm.

[0011] In the above scheme, the second section protrudes a certain distance from the second side, which can provide sufficient welding space. On the one hand, it can ensure that the solder covers the gap between the end of the wire harness and the wall of the welding hole. On the other hand, it can ensure that the solder can completely wrap the end of the wire harness to form a complete "wrap-type solder joint", avoiding cold solder joints caused by insufficient solder adhesion area and improving welding reliability.

[0012] Optionally, the first wire harness further includes a first wire harness body, the first wire harness body connects the first segment and the second segment, the first wire harness body, the first segment and the second segment are all constructed as conductive elements, and the first wire harness further includes an insulating layer that covers the first wire harness body.

[0013] In the above scheme, the first wire harness body can form a conductive path with the first segment and the second segment. The insulating layer can isolate the first wire harness body from other electronic components inside the controller, reducing the probability of short circuit caused by the first wire harness body contacting adjacent conductive parts. In other words, the insulating layer can effectively isolate the first wire harness body from external conductive parts, forming an electrical isolation barrier, reducing the risk of short circuit and improving reliability.

[0014] Optionally, the first wire harness also includes a tin-plated layer that covers the second segment and is soldered to the circuit board.

[0015] In the above solution, during soldering, the tin-immersion layer can directly fuse with the solder, which helps to ensure that the solder joint between the second segment and the circuit board is uniform and firm, can withstand greater tensile and shear stress, reduces the occurrence of loosening or breakage of the solder joint between the first wire harness and the circuit board, and at the same time reduces the chance of oxide layer forming on the copper end, which hinders solder adhesion. There is no need to scrape off the oxide layer and apply flux during the soldering process, which improves the soldering efficiency and makes soldering more convenient.

[0016] Optionally, along the length direction of the first wire harness, the dimension of the second segment is L, satisfying: 7mm≤L≤9mm.

[0017] In the above scheme, since the size L of the second segment meets the above range, on the one hand, it can ensure that the solder has sufficient adhesion space to form a stable solder joint. The molten solder can fully wrap the second segment, ensuring that the solder joint has sufficient size, improving the strength of the soldering, and reducing the probability of solder breakage and detachment between the second segment and the solder hole. At the same time, it can reduce the probability of interference between the insulation layer and the circuit board, ensuring the reliability of current transmission. On the other hand, it helps to reduce the probability of the second segment interacting with other electronic components, ensuring electrical safety. It also helps to shorten the electrical distance between the first wire harness and other electronic components, reducing the space occupied, making the internal space utilization of the controller more efficient and the structure more compact.

[0018] Optionally, the insulation layer is spaced apart from the first side surface along the length direction of the first wire harness.

[0019] In the above scheme, when assembling the controller, the first wire harness needs to be positioned and installed together with the connector body, so that there is a certain amount of movement between the insulation layer and the first side, which is convenient to adapt to different distances between the PCB board and the housing, reduce the impact of the insulation layer on the circuit board, reduce electrical interference to the signals on the circuit board, and improve reliability.

[0020] Optionally, there are two first wire harnesses, and the first segments of the two first wire harnesses are electrically connected to the positive and negative terminals of the power supply, respectively.

[0021] There are two welding holes, and the second segment of each first wire bundle mates with the corresponding welding hole.

[0022] In the above scheme, two welding holes are used to weld the second segment of the corresponding first wire harness. With this configuration, the two independent welding holes can provide precise docking position guidance for the second segment of the corresponding first wire harness. There is no need to spend a lot of time finding or judging where the wire harness should be connected. Just place the second segment of the corresponding first wire harness accurately according to the position of the welding hole to achieve alignment. This improves the ease of installation, reduces the probability of wire harness crossing and tangling during the process, and greatly saves the internal space of the controller, making the layout more compact.

[0023] Optionally, the first wiring harness is an XLPE conductor.

[0024] In the above scheme, after the insulation layer of XLPE (cross-linked polyethylene) wire is cross-linked, the molecular structure forms a three-dimensional network structure, which significantly improves the high voltage resistance. During long-term high voltage operation of the controller, it can effectively avoid short circuits between the positive and negative poles caused by insulation layer breakdown. At the same time, the volume resistivity of XLPE insulation layer is much higher than that of PVC, which can reduce the leakage current loss of insulation layer and reduce the overall energy consumption of the controller.

[0025] Secondly, embodiments of this application provide a vehicle including a controller as described in any embodiment.

[0026] The vehicle proposed in this application, having the controller described in any one of the embodiments, improves assembly efficiency, space utilization, controller reliability, and user experience. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment.

[0043] With the development of the all-in-one trend of electric vehicles, the structure of current electric vehicle compressor controllers is becoming more and more compact. Some compressor manufacturers use connectors with built-in copper busbars, which are directly soldered onto the circuit board. This method is simple to install and has high efficiency. However, since connector manufacturers need to fix the copper busbars on the connector mold during the production process, the manufacturing cost is high. Moreover, unless a new mold is made, other specifications of copper busbars cannot be used, making the method relatively limited.

[0044] Other compressor manufacturers use a more traditional wiring harness connection method, where one end is inserted into a high-pressure connector and the other end is locked in the circuit board with a cold-pressed terminal. This wiring harness structure is simple and can be of different lengths depending on the relative position between the controller cavity and the circuit board. However, due to the compact internal structure of the electric compressor controller, the cold-pressed terminal will occupy a certain space. In actual use, the terminal position can only be fixed manually, which cannot be automated and the fixing process is relatively troublesome.

[0045] In related technologies, high-voltage connectors with copper busbar structures have high manufacturing costs due to the integral molding of the copper busbar and connector. Furthermore, the copper busbar structure is relatively simple. If the distance between the PCB board and the housing does not meet the requirements of the copper busbar, it cannot be used and a mold of the corresponding specification must be customized. Traditional wire harnesses can meet various length requirements, but in the compact environment of something like the inside of an electric compressor controller, they have disadvantages such as inconvenient wire bending, difficult installation, and inability to achieve automated wire installation, resulting in inconvenience in use.

[0046] Therefore, improving the ease of installation of the controller is a technical problem that urgently needs to be solved.

[0047] In view of this, in order to improve the ease of installation and assembly efficiency of the controller, this application provides a controller for a vehicle. The connector 300 includes a connector body 310 and a first wire harness 320 disposed on the connector body 310. Along the length direction of the first wire harness 320, the first wire harness 320 includes a first segment 321 and a second segment 322 disposed opposite to each other. The first segment 321 is adapted to be electrically connected to a power source, and the second segment 322 is fitted into a solder hole 210 and electrically connected to a circuit board 200. With this configuration, the first wire harness 320 can be assembled with the circuit board 200 without bending it, which greatly reduces the space occupied by the first wire harness 320 inside the controller. At the same time, the solder hole 210 can provide a clear guide for the first wire harness 320. Assembly can be completed simply by aligning the second segment 322 with the solder hole 210 and inserting it. In addition, it is easy to adapt to different distances between the PCB board and the housing, which improves the ease of use and assembly efficiency.

[0048] The following description, with reference to the accompanying drawings, describes a controller for a vehicle according to an embodiment of this application.

[0049] Please refer to Figure 1 and Figure 2 A controller for a vehicle according to a first aspect of this application includes a housing 100, a circuit board 200, and a connector 300.

[0050] The housing 100 has an internal accommodating space 100a; it is understood that the accommodating space 100a can be used to accommodate electronic components, including wire harnesses. In other words, the housing 100 can encapsulate electronic components, including wire harnesses, inside, isolating them from harsh external environments and reducing the impact of dust, liquids and other impurities on the electronic components.

[0051] Meanwhile, the housing 100 provides a fixed mounting position for the circuit board 200 and connector 300, ensuring that the components maintain a stable relative position in the vibration environment of vehicle driving, and avoiding electrical connection failure due to component displacement.

[0052] The circuit board 200 is disposed in the receiving space 100a. The circuit board 200 is provided with solder holes 210, which penetrate the circuit board 200 along the thickness direction. It can be understood that the circuit board 200 is disposed in the receiving space 100a to avoid the components being exposed and to reduce the probability of external interference affecting the performance of the circuit board 200.

[0053] The soldering hole 210 can be used to connect the wire harness. When the wire harness is fixed to the circuit board 200 through the soldering hole 210, the soldering hole 210 can provide a clear docking point for the electrical connection between the connector 300 wire harness and the circuit board 200, which helps to ensure accurate positioning of the wire harness and reduces the chance of the wire harness falling off due to vibration after being soldered to the circuit board 200.

[0054] In addition, the through-hole 210 allows the wire harness to pass through one side of the circuit board 200 and be soldered on the other side. In other words, the wire harness can directly pass through the solder hole 210 and connect to the circuit board 200, which makes soldering easier and improves assembly efficiency. At the same time, it can increase the contact area between the wire harness and the solder hole 210, making the solder joint stronger and effectively reducing the occurrence of solder joint fatigue fracture caused by vehicle vibration.

[0055] The connector 300 includes a connector body 310 and a first wire harness 320 disposed on the connector body 310. Along the length of the first wire harness 320, the first wire harness 320 includes a first segment 321 and a second segment 322 disposed opposite to each other. The first segment 321 is adapted to be electrically connected to a power source, and the second segment 322 mates with a solder hole 210 and is electrically connected to the circuit board 200. This arrangement avoids the difficulty of bending wires caused by the space occupied by cold-pressed terminals, making it easier to flexibly adapt to the complex internal spatial layout of the controller. On the other hand, it facilitates adaptation to different distances between the PCB board and the housing, improving ease of use and assembly efficiency.

[0056] As an example, the length of the first wiring harness 320 can be adjusted according to the relative position of the controller cavity and the circuit board 200. On the one hand, it can adapt to controllers of different sizes, and on the other hand, it can reduce the space occupied by the first wiring harness 320, making it more flexible, more convenient to use, and helping to improve assembly efficiency.

[0057] Understandably, in traditional vehicle controller assembly, if surface welding of the wire harness is used, without welding holes 210 or through holes, the contact point between the wire harness and the copper foil of the circuit board 200 must be precisely located first, and then the wire harness posture must be manually fixed to avoid displacement during welding. At the same time, it is also necessary to avoid the dense components on the circuit board 200, such as resistors and capacitors. The operating space is narrow and the error tolerance is low. In this application, the welding hole 210 can provide a clear guide for the first wire harness 320. The second segment 322 can be inserted simply by aligning it with the welding hole 210 to complete the assembly, which improves the ease of use and assembly efficiency.

[0058] After the first wire harness 320 passes through the welding hole 210, welding points are formed only around the welding hole 210. The hole wall of the welding hole 210 will form a radial constraint on the second segment 322. In other words, the welding hole 210 can limit the second segment 322 of the first wire harness 320, reducing the probability of the first wire harness 320 shaking in the accommodating space 100a. This setting reduces the probability of the first wire harness 320 having spatial conflicts with other components, improves space utilization efficiency, and makes the overall structure more compact.

[0059] As an example, the controller can be the controller of the compressor on the vehicle. The circuit board 200 can be equipped with electronic components or circuits for current conversion. The power source can be the vehicle's battery pack. As such, the current can flow from the power source to the first segment 321, pass through the first wiring harness 320, and then enter the circuit board 200 through the second segment 322. After being converted by the electronic components or circuits on the circuit board 200, the current enters the compressor body to drive the compressor body to work.

[0060] In other words, the second segment 322 of the first wire harness 320 is tinned and soldered to the circuit board 200, and the first segment 321 of the first wire harness 320 is electrically connected to the connector 300. After the connector 300 is connected to the power supply, the power supply of the compressor controller can be directly realized, so that the connector wire harness assembly can be directly fixed to the electrical structure, reducing the possibility of failure during cold-pressed terminal crimping and fixing.

[0061] The controller can be installed in the vehicle as part of the compressor, which improves assembly efficiency, helps to increase the space utilization of the vehicle, enhances the reliability of the controller, and improves the user experience.

[0062] In other embodiments, please refer to Figure 1 and Figure 2 Along the thickness direction of the circuit board 200, the circuit board 200 has a first side 220 and a second side 230 that are arranged opposite to each other. The first side 220 is closer to the connector body 310 than the second side 230. It can be understood that the second side 230 can fix the second segment 322 and is electrically connected to the second segment 322. The first segment 321 and the first side 220 are located on the same side of the circuit board 200, and the second segment 322 and the second side 230 are located on the other side of the circuit board 200 in the same direction, making the overall structure more compact and regular.

[0063] While reducing space occupation, the compact structure also makes more rational use of the internal space of the controller, which can accommodate more necessary components in a limited space, thus helping to improve space utilization. As a result, there is no need to perform cross wiring or cross the two sides of the circuit board 200 in a complex space during assembly, which reduces assembly difficulty and significantly improves assembly efficiency.

[0064] The second segment 322 passes through the welding hole 210 and protrudes from the second side 230. Understandably, in traditional designs, the wire harness needs to be bent at a certain angle to avoid the connector body 310 before welding. In this embodiment, the second segment 322 passes through the welding hole 210 and sequentially through the first side 220 and the second side 230, reducing the bending stress caused by the wire harness bending, lowering the probability of insulation layer 325 damage and wire breakage, effectively avoiding premature wire harness failure due to bending, and improving the overall reliability of the controller.

[0065] At the same time, it also helps to shorten the overall length of the first wire harness 320, shorten the connection distance of the first wire harness 320, reduce current transmission loss, avoid local heating caused by excessive wire harness length, improve electrical performance stability, and reduce friction between the first wire harness 320 and the box 100, thus reducing the occurrence of wire harness wear caused by friction between the first wire harness 320 and the box 100.

[0066] In other embodiments, please refer to Figure 1 and Figure 2 The length of the second segment 322 protruding from the second side 230 is not less than 2mm.

[0067] In the above scheme, the second segment 322 protrudes a certain distance from the second side 230, which can provide sufficient welding space. On the one hand, it can ensure that the solder covers the gap between the end of the wire harness and the wall of the welding hole 210. On the other hand, it can ensure that the solder can completely wrap the end of the wire harness to form a complete "wrap-type solder joint", avoiding cold solder joints caused by insufficient solder adhesion area and improving welding reliability.

[0068] Meanwhile, the second section 322 protruding a certain distance from the second side 230 facilitates accurate positioning of the welding position during the welding process, which helps to improve welding efficiency. When heated, the solder can melt quickly and fall off from the end of the wire harness, reducing the occurrence of solder sticking to the hole wall and avoiding insufficient solder or cold solder joints, which helps to improve welding reliability.

[0069] In addition, the 2mm long solder joint and the longer fixed section formed by the wire harness end help to disperse the impact force during vibration, avoid stress concentration at the edge of the solder hole 210, reduce the probability of the hole wall cracking caused by the lateral tensile force generated by vibration, and at the same time prevent the wire harness end from being squeezed to the surface of the circuit board 200 due to excessively short protrusion, reduce the occurrence of solder joint deformation under stress, and ensure the stability of the solder structure.

[0070] As an example, the length of the second segment 322 extending beyond the second side 230 can be determined according to actual needs. That is, the length of the second segment 322 protruding beyond the second side 230 can be 2mm, 2.3mm, 2.5mm, 2.8mm, 3mm, 3.5mm, 4mm, 4.5mm or 5mm, and this application does not impose any restrictions on this.

[0071] In other embodiments, please refer to Figure 1 , Figure 2 and Figure 3 The first wire harness 320 also includes a first wire harness body 323, which connects the first segment 321 and the second segment 322. It can be understood that the first wire harness body 323 can serve to connect the first segment 321 and the second segment 322.

[0072] The first wire harness body 323, the first segment 321, and the second segment 322 are all constructed as conductive components. In other words, the first wire harness body 323, the first segment 321, and the second segment 322 can form a conductive path to ensure that the current can be stably transmitted to the circuit board 200 and avoid the interruption of current transmission due to the lack of a unified connection carrier.

[0073] The first wiring harness 320 also includes an insulating layer 325, which covers the first wiring harness body 323. It is understood that the insulating layer 325 can isolate the first wiring harness body 323 from other electronic components inside the controller, reducing the probability of a short circuit caused by contact between the first wiring harness body 323 and adjacent conductive parts. In other words, the insulating layer 325 can effectively isolate the first wiring harness body 323 from external conductive parts, forming an electrical isolation barrier, reducing the risk of short circuits, and improving reliability.

[0074] As an example, the insulating layer 325 can be made of high-voltage resistant insulating materials such as PVC and silicone rubber, and this application does not limit this.

[0075] In other embodiments, please refer to Figure 1 , Figure 2 and Figure 3 The first wire harness 320 also includes a tin-dip layer 324, which covers the second segment 322 and is soldered to the circuit board 200. Understandably, during soldering, the tin-dip layer 324 can directly fuse with the solder, helping to ensure a uniform and firm solder joint between the second segment 322 and the circuit board 200, allowing it to withstand greater tensile and shear stresses and reducing the occurrence of loosening or breakage of the solder joint between the first wire harness 320 and the circuit board 200.

[0076] At the same time, it reduces the chance of an oxide layer forming on the copper end, which hinders solder adhesion. There is no need to scrape off the oxide layer or apply flux during the soldering process, which improves soldering efficiency and makes soldering more convenient.

[0077] In other embodiments, please refer to Figure 3 and Figure 4 Along the length of the first wire harness 320, the dimension of the second segment 322 is L, which satisfies: 7mm≤L≤9mm.

[0078] In the above scheme, since the size L of the second segment 322 meets the above range, on the one hand, it can ensure that the solder has enough adhesion space. During soldering, the solder needs to wrap the gap between the second segment 322 and the wall of the solder hole 210, and at the same time form a stable solder joint. Especially when used with the immersion tin layer 324, it needs to be long enough to ensure that the immersion tin layer 324 and the solder are fully fused. The molten solder can fully wrap the second segment 322, ensuring that the solder joint has sufficient size, improving the firmness of the soldering, reducing the probability of the solder breaking off between the second segment 322 and the solder hole 210, and at the same time reducing the probability of interference between the insulating layer 325 and the circuit board 200, ensuring the reliability of current transmission.

[0079] On the other hand, it helps reduce the chance of the second segment 322 interfering with other electronic components, ensuring electrical safety, and helps shorten the electrical distance between the first wiring harness 320 and other electronic components, reducing the space occupied, making the internal space of the controller more efficient and the structure more compact.

[0080] Optionally, the dimension L of the second segment 322 can be 7mm, 7.5mm, 8mm, 8.5mm, or 9mm, and this application does not impose any restrictions on this.

[0081] In other embodiments, please refer to Figure 1 and Figure 2Along the length of the first wiring harness 320, the insulating layer 325 is spaced apart from the first side surface 220. It is understood that during controller assembly, the first wiring harness 320 needs to be positioned and installed together with the connector body 310, allowing for a certain amount of movement between the insulating layer 325 and the first side surface 220. This facilitates adaptation to different distances between the PCB board and the housing, reduces the impact of the insulating layer 325 on the circuit board 200, reduces electrical interference to signals on the circuit board 200, and improves reliability.

[0082] Meanwhile, when the insulating layer 325 suffers minor damage due to aging or vibration friction, the probability of the exposed first wire harness body 323 coming into contact with electronic components on the circuit board 200 is reduced, lowering the chance of accidental short circuits and reducing the occurrence of signal lines being damaged by power supply voltage and burning out signal chips. The spaced design allows the insulating layer 325 to maintain a safe distance from the first side 220. Even if the insulating layer 325 is partially damaged, the conductive body cannot touch the copper foil of the circuit board 200, eliminating the risk of short circuit interference from a spatial perspective and resulting in higher reliability.

[0083] In other embodiments, please refer to Figure 1 and Figure 2 There are two first wire harnesses 320. The first segments 321 of the two first wire harnesses 320 are respectively electrically connected to the positive and negative terminals of the power supply. It can be understood that the two first wire harnesses 320 can each play the role of transmitting current. The controller can be powered by connecting the two first wire harnesses 320 to the power supply. The two wire harnesses can respond simultaneously, quickly providing sufficient power to the controller and reducing the voltage drop and power supply delay caused by insufficient current carrying capacity of a single wire harness.

[0084] Meanwhile, using two first harnesses 320 connected to the positive and negative terminals of the power supply reduces the chance of harnesses crossing and tangling during the process, significantly saving internal space in the controller and making the layout more compact.

[0085] There are two welding holes 210, and the second segment 322 of each of the first wire harnesses 320 mates with the corresponding welding hole 210. It can be understood that the two welding holes 210 are used to weld the second segment 322 of the corresponding first wire harness 320. This configuration allows the two independent welding holes 210 to provide precise alignment guidance for the second segment 322 of the corresponding first wire harness 320. It eliminates the need to spend a lot of time searching for or determining the correct connection position of the wire harness; alignment can be achieved simply by accurately placing the second segment 322 of the corresponding first wire harness 320 according to the position of the welding hole 210, thus improving installation convenience.

[0086] This precise positioning greatly reduces the complexity of the installation process and the tediousness of the positioning process, making installation more convenient.

[0087] During operation, simply insert the second segment 322 of each of the two first wire harnesses 320 into their respective welding holes 210, and then weld them in place. Compared with complex single-hole multi-wire harness or multi-line adapter installation methods, this method reduces cumbersome steps such as wire harness cross-winding and adapter connections.

[0088] In some embodiments, the first wire harness 320 is an XLPE conductor. It is understood that the insulation layer 325 of the XLPE (cross-linked polyethylene) conductor, after cross-linking treatment, forms a three-dimensional network structure, significantly improving its high-voltage resistance. During long-term high-voltage operation of the controller, it can effectively prevent short circuits between the positive and negative electrodes caused by the breakdown of the insulation layer 325. Simultaneously, the volume resistivity of the XLPE insulation layer 325 is much higher than that of PVC, which can reduce leakage current loss of the insulation layer 325 and lower the overall energy consumption of the controller.

[0089] Meanwhile, the XLPE wires can resist external vibrations, ensuring a firm connection between the first wire harness 320 and the welding hole 210, making them less prone to bending, reducing the space occupied inside the controller, and making the layout more compact.

[0090] In addition, when the compressor is working, the internal temperature of the controller is high. The XLPE insulation layer 325 can still maintain good mechanical strength and insulation performance at high temperature, reducing the occurrence of insulation layer 325 damage caused by high temperature aging, greatly reducing the risk of failure caused by wire harness aging, reducing the probability of short circuit caused by insulation layer 325 cracking and exposing conductive body, and extending the overall service life of the controller.

[0091] As an example, XLPE conductors refer to cross-linked polyethylene insulated power cables, which are divided into single-core cables and three-core cables. The conductor is sequentially covered with at least a semiconductor inner shield, a cross-linked polyethylene shield, and a semiconductor outer shield. The cross-linked polyethylene shield is constructed as an XLPE insulation layer 325, and is covered with a polyvinyl chloride sheath on the outermost layer. In a specific embodiment, the insulation layer 325 is constructed as a polyvinyl chloride sheath. The XLPE conductor is stripped of its outermost polyvinyl chloride sheath to form a first segment 321, a first wire harness body 323, and a second segment 322.
