Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0020] According to the first aspect of this application, referring to Figures 1 to 6 This disclosure provides a CCS assembly, which includes a bracket 200, a limiting member 300, and a wire harness 500. The limiting member 300 is detachably connected to the bracket 200, and the limiting member 300 and the bracket 200 restrict a wire passage 400. The wire harness 500 passes through the wire passage 400.

[0021] In related technologies, once cable ties are cut or damaged, they cannot be reused, requiring the purchase of new cable ties when repairing or replacing the wire harness 500. This application uses a detachable connection between the limiting member 300 and the bracket 200, allowing the wire harness 500 to be disassembled and reinstalled without damaging the components, avoiding material waste and reducing the long-term cost of CCS components.

[0022] In some embodiments, the limiting member 300 is engaged with the bracket 200.

[0023] The snap-fit ​​design allows for quick connection or separation of the limiting component 300 and the bracket 200 without the need for tools, greatly improving installation and disassembly efficiency. This design is particularly suitable for scenarios requiring frequent maintenance or component replacement, reducing operational difficulty and time costs.

[0024] If the limiter 300 or the bracket 200 is damaged, the damaged part can be replaced individually without replacing the entire assembly. This detachable design reduces the risk of the entire system becoming unusable due to the failure of a single component, thereby reducing maintenance costs.

[0025] The snap-fit ​​mechanism ensures a tight fit between the limiting component 300 and the bracket 200, effectively restricting the movement of the wire harness 500 and ensuring its stability during use.

[0026] Because the snap-fit ​​design between the limiting component 300 and the bracket 200 allows for reuse, it reduces waste generated from single-use applications, meeting the requirements of environmental protection and sustainable development.

[0027] In some embodiments, the limiting member 300 has a buckle 310 at each of its opposite ends, and the buckle 310 is fastened to the bracket 200.

[0028] Thus, by restricting the positions of the two ends of the limiting member 300 by the two fasteners 310, the relative position of the limiting member 300 and the bracket 200 is relatively stable, and the limiting member 300 is not easy to detach from the bracket 200, so that the limiting member 300 can provide a relatively stable limit for the wire harness 500.

[0029] The buckles 310 at both ends of the limiting member 300 are respectively fastened to the bracket 200, forming a double fixing point. Compared with single-point fixing or simple snap-fit ​​structure, this design can provide stronger fixing force and reduce the occurrence of loosening or displacement of the limiting member 300 during use.

[0030] The buckles 310 at both ends can evenly distribute the tension of the wire harness 500 onto the bracket 200, avoiding structural damage due to excessive local stress, thereby extending the service life of the CCS assembly.

[0031] In some embodiments, the CCS component includes a first bus 710 and a second bus 720, and a plurality of wire harnesses 500 are provided, including a first wire harness 510 and a second wire harness 520. The first wire harness 510 is connected to the first bus 710, the second wire harness 520 is connected to the second bus 720, and a limiting member 300 is disposed between the first bus 710 and the second bus 720.

[0032] In this way, the limiting channel can simultaneously accommodate the first wiring harness 510 and the second wiring harness 520, making the layout of the CCS assembly more compact. When the first wiring harness 510 and the second wiring harness 520 are damaged, the limiting member 300 can be removed from the bracket 200 for easy repair and replacement of the first wiring harness 510 and the second wiring harness 520 of the CCS assembly. Furthermore, the limiting member 300 does not need to cross the first busbar 710 and the second busbar 720 to restrict the passage channel 400 for the first wiring harness 510 and the second wiring harness 520, which is beneficial for the miniaturization of the CCS assembly.

[0033] In some embodiments, a plurality of first busbars 710 are provided, a first wiring harness 510 includes a plurality of first wires 511, a first wire 511 is connected to a first busbar 710, a plurality of second busbars 720 are provided, a second wiring harness 520 includes a plurality of second wires 521, a second wire 521 is connected to a second busbar 720, and the CCS assembly also includes a first tape and a second tape, the first tape binding the plurality of first wires 511 and the second tape binding the plurality of second wires 521.

[0034] Multiple first wires 511 are bundled together with first tape, and multiple second wires 521 are bundled together with second tape. This centralized management method makes the wire harness 500 more organized, avoids messy crossover between wire harnesses 500, and improves the overall layout aesthetics and maintainability of the wire harness 500.

[0035] The first wire 511 and the second wire 521 are respectively connected to different busbars 700 and are distinguished by tape, making the partitions of the entire CCS assembly clearer and facilitating quick location and operation by maintenance personnel.

[0036] The method of using a first tape to bind multiple first wires 511 and a second tape to bind multiple second wires 521 facilitates quick disassembly and installation. Maintenance personnel can easily untie the first and second tapes to replace damaged first wires 511 and second wires 521 without the need for complicated tools.

[0037] Since the first wire 511 and the second wire 521 are bundled separately, the first wire 511 or the second wire 521 can be operated individually during maintenance without affecting the other, thus improving maintenance efficiency.

[0038] The tape can provide some physical protection to prevent the wire harness 500 from being damaged by external mechanical forces.

[0039] In some embodiments, the limiting member 300 is provided with a plurality of limiting members.

[0040] Multiple limiting components 300 can provide multiple fixing points, allowing the wire harness 500 to be stably supported and fixed in multiple positions. Compared to a single limiting component 300, this multi-point fixing method can more effectively prevent the wire harness 500 from loosening or shifting due to vibration or impact during operation.

[0041] Multiple limiting components 300 can be flexibly arranged according to the routing and layout of the wire harness 500, so that the wire harness 500 can be effectively fixed in different areas. This zoned fixing method can better adapt to complex wire harness 500 layouts.

[0042] Multiple limiters 300 provide redundant fixing points, so that even if one limiter 300 fails, the other limiters 300 can still keep the harness 500 stable.

[0043] In some embodiments, the CCS assembly includes a bus 700 disposed on the bracket 200, and a wire harness 500 is laser-welded to the bus 700 via a nickel-plated terminal 600. In some embodiments, multiple bus 700s are provided, including a first bus 710 and a second bus 720. In some embodiments, a first wire 511 is connected to a corresponding first bus 710 via a nickel-plated terminal 600, and a second wire 521 is connected to a corresponding second bus 720 via a nickel-plated terminal 600.

[0044] Laser welding is a high-precision, high-strength connection method that ensures a strong and reliable connection between the wire harness 500 and the busbar 700. The nickel-plated terminal 600 and the busbar 700 can also be securely connected via laser welding.

[0045] Laser welding is a highly efficient joining method that can easily achieve automated production, greatly improving production efficiency and reducing production costs.

[0046] Laser welding ensures consistent quality at each weld point, reduces errors caused by manual operation, and improves the overall quality of the product.

[0047] In some embodiments, the CCS assembly includes a bus 700 and double-sided adhesive, the bus 700 being bonded to the bracket 200 by the double-sided adhesive.

[0048] Double-sided tape can quickly fix the busbar 700 to the bracket 200 without the need for complicated mechanical fasteners or welding processes, greatly simplifying the assembly process.

[0049] The double-sided adhesive provides sufficient bonding strength to ensure that the busbar 700 does not loosen or fall off during operation, thereby improving the stability of the entire CCS assembly.

[0050] Double-sided tape has good durability and can maintain a stable bonding effect during long-term use.

[0051] The use of double-sided tape reduces the need for additional fasteners, making the entire CCS assembly more compact and saving space.

[0052] In some embodiments, the support 200 is configured as a vacuum-formed support 200. Vacuum forming molds are relatively simple and low-cost, and compared to injection molds, their development difficulty is lower, effectively reducing initial equipment investment. The vacuum forming process can adjust the material thickness and shape according to requirements, reducing material waste and thus lowering raw material costs. Vacuum forming has a short cycle time and fast production speed, making it suitable for mass production and further reducing the cost per unit product. Vacuum-formed supports 200 typically use lightweight, thin flame-retardant PC films and other materials, which are lighter than traditional injection-formed supports 200, effectively reducing the overall weight of the CCS module and improving the space utilization of the battery pack. The PC material commonly used in vacuum-formed supports 200 has good insulation properties, meeting the electrical insulation requirements of CCS modules in the battery pack. Vacuum-formed products have good corrosion resistance, adapting to the complex chemical environment inside the battery pack. The vacuum forming process can quickly adjust the product shape and size according to different design requirements, adapting to the diverse structural requirements of CCS modules. Vacuum-formed supports 200 can be integrated with other components through simple processes such as cutting and hot riveting, simplifying the production process and facilitating automated assembly. The materials used in the 200 vacuum forming stand, such as PC, have good recyclability and meet environmental protection requirements.
