Description

Technical Field

[0001] This utility model relates to a cable integration device, specifically a flexible cable integration device for CCS modules, belonging to the field of CCS module technology. Background Technology

[0002] The CCS module, or Cell Connector Assembly, is the electrical connection structure within a battery module. It integrates information acquisition components (such as wiring harnesses, PCBs, FPCs, FFCs, etc.), plastic structural components, copper and aluminum busbars, and other parts into a single module installed within the battery module. This module enables high-voltage series and parallel connection of battery cells, battery temperature sampling, cell voltage sampling, and overcurrent protection. It uses conductive materials such as copper and aluminum busbars to achieve series and parallel connections between cells, ensuring normal current transmission. With the help of information acquisition components, such as FPCs (Flexible Printed Circuit Boards), it monitors key parameters such as battery temperature and voltage in real time. The CCS module's overcurrent protection ensures that the battery module can quickly cut off current in abnormal situations, protecting the battery and the system.

[0003] A Chinese utility model patent (publication number: CN217334309U) discloses an integrated CCS module, which reduces the assembly process in module and PACK production. The integration of the aluminum busbar and FFC busbar can be completed by the supplier or processed in parallel during the assembly of the module body, which greatly reduces the production cycle and production cost. The integrated CCS module has low requirements for the assembly line equipment or tooling fixtures of the module or PACK, and can be quickly put into production line production.

[0004] While its design greatly facilitates the processing and production of the module body, significantly improving production efficiency and the overall integration of the module, the design of connecting the FFC busbar and the aluminum busbar by welding also reveals certain limitations in actual use:

[0005] Due to the characteristics of the welded connection, the FFC busbar and the aluminum busbar form a relatively strong but inflexible bond. This means that if the FFC busbar fails or needs to be upgraded or replaced during later use, maintenance personnel will face greater operational difficulties because the welded points are difficult to disassemble and are prone to secondary damage during disassembly. Therefore, this connection method greatly limits the maintenance convenience and replaceability of the FFC busbar, and increases the cost and complexity of later maintenance.

[0006] To address this, a flexible cabling integration device for CCS modules is proposed. Utility Model Content

[0007] In view of this, the present invention provides a flexible cabling integration device for CCS modules to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0008] The technical solution of this utility model embodiment is implemented as follows: A CCS module flexible cable integration device includes a main component, the main component including a plastic substrate, a strip-shaped limiting groove, two L-shaped limiting plates, a threaded column, two guide columns, a silicone partition and a limiting pressure plate;

[0009] The strip-shaped limiting groove is formed in the middle of the upper surface of the plastic substrate. The two L-shaped limiting plates are symmetrically fixedly connected to the upper surface of the plastic substrate. The two L-shaped limiting plates are symmetrically located on both sides of the strip-shaped limiting groove. The limiting pressure plate is slidably connected to the inner side wall of the L-shaped limiting plate. The two guide posts are symmetrically fixedly connected to the upper surface of the limiting pressure plate. The bottom end of the threaded post is rotatably connected to the upper surface of the limiting pressure plate. The silicone partition is bonded to the lower surface of the limiting pressure plate.

[0010] More preferably, the top end of the threaded post penetrates the upper surface of the L-shaped limiting plate and is threadedly connected to the L-shaped limiting plate, and the guide post is slidably connected to the inside of the L-shaped limiting plate.

[0011] More preferably, a circuit board is provided inside the strip-shaped limiting groove, and the outer side wall of the circuit board is attached to the inner side wall of the strip-shaped limiting groove.

[0015] More preferably, a flexible connecting cable is installed on the upper surface of the aluminum busbar.

Detailed Implementation

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figures 1-4 As shown, this utility model embodiment provides a CCS module flexible cable integration device, including a main component 101. The main component 101 includes a plastic substrate 11, a strip-shaped limiting groove 12, two L-shaped limiting plates 13, a threaded post 14, two guide posts 15, a silicone partition 16, and a limiting pressure plate 17.

[0029] A strip-shaped limiting groove 12 is formed in the middle of the upper surface of the plastic substrate 11. A circuit board 18 is disposed inside the strip-shaped limiting groove 12. The outer side wall of the circuit board 18 is attached to the inner side wall of the strip-shaped limiting groove 12. The position of the circuit board 18 can be limited by the strip-shaped limiting groove 12. In the CCS module, the circuit board 18 integrates a thermistor and a voltage sampling point to collect the temperature and voltage signals of the battery cell in real time and transmit them to the battery management system through a connector.

[0030] The circuit board 18 is a flexible circuit board, which can be bent and adapt to complex spatial layouts, thereby improving the space utilization of the battery pack;

[0031] Two L-shaped limiting plates 13 are symmetrically fixedly connected to the upper surface of the plastic substrate 11. The two L-shaped limiting plates 13 are symmetrically located on both sides of the strip-shaped limiting groove 12. The limiting pressure plate 17 is slidably connected to the inner side wall of the L-shaped limiting plate 13. The bottom end of the threaded column 14 is rotatably connected to the upper surface of the limiting pressure plate 17. The top end of the threaded column 14 is provided with a locking knob. The top end of the threaded column 14 passes through the upper surface of the L-shaped limiting plate 13 and is threadedly connected to the L-shaped limiting plate 13. When the locking knob is rotated, the locking knob drives the threaded column 14 to rotate. Since the threaded column 14 is threadedly connected to the L-shaped limiting plate 13, the threaded column 14 can drive the limiting pressure plate 17 to move up or down.

[0032] The silicone partition 16 is bonded to the lower surface of the limiting pressure plate 17, and the lower surface of the silicone partition 16 is attached to the upper surface of the circuit board 18. The limiting pressure plate 17 contacts the circuit board 18 through the silicone partition 16, thereby preventing the circuit board 18 from being crushed.

[0033] When installing the circuit board 18, place the circuit board 18 in the strip-shaped limiting groove 12, and then turn the locking knob clockwise. The locking knob drives the threaded column 14, and the threaded column 14 pushes the limiting pressure plate 17 to move downward. The limiting pressure plate 17 fits against the circuit board 18 through the silicone partition 16, and the circuit board 18 is then installed.

[0034] When disassembling circuit board 18, turn the locking knob counterclockwise. At this time, the limiting pressure plate 17 moves upward, the silicone partition 16 separates from the circuit board 18, the limiting of the circuit board 18 is released, and the circuit board 18 can be taken out.

[0035] In one embodiment, two guide posts 15 are symmetrically fixedly connected to the upper surface of the limiting plate 17, and the guide posts 15 are slidably connected to the inside of the L-shaped limiting plate 13. The guide posts 15 can guide the limiting plate 17 so that the limiting plate 17 can be raised and lowered vertically.

[0036] In one embodiment, a side limiting groove 21 is formed on the upper surface of the plastic substrate 11, and an aluminum busbar 19 is embedded inside the side limiting groove 21. The aluminum busbar 19 is located on both sides of the circuit board 18. The side limiting groove 21 can limit the position of the aluminum busbar 19. In the CCS module, the aluminum busbar 19 serves as a conductive part, which can realize high-voltage series and parallel connection between cells to ensure the efficient operation of the battery system.

[0037] In one embodiment, a flexible connecting cable 20 is installed on the upper surface of the aluminum busbar 19. The circuit board 18 is connected to the aluminum busbar 19 through the flexible connecting cable 20. The flexible connecting cable 20 is connected to the circuit board 18 and the aluminum busbar 19 through plug-in connectors, thereby facilitating installation or disassembly.

[0038] When this utility model is in operation: the series and parallel connection between the cells is realized through the aluminum busbar 19 to ensure the normal transmission of current; the circuit board 18 monitors key parameters such as battery temperature and voltage in real time and transmits them to the battery management system through the connector.

[0039] When the circuit board 18 needs to be disassembled for maintenance or replacement, first disconnect the flexible connecting cable 20 on the circuit board 18, and then turn the locking knob counterclockwise. The locking knob will drive the threaded post 14 to rotate. Since the threaded post 14 is threadedly connected to the L-shaped limit plate 13, the threaded post 14 can drive the limit pressure plate 17 to move upward, and the silicone partition 16 will separate from the circuit board 18. At this time, the limit on the circuit board 18 will be released, and the circuit board 18 can be taken out for maintenance or replacement.

[0040] When installing the circuit board 18, insert the circuit board 18 into the strip-shaped limiting groove 12, and then turn the locking knob clockwise. The threaded column 14 pushes the limiting pressure plate 17 to move downward. The limiting pressure plate 17 fits against the circuit board 18 through the silicone partition 16, and the circuit board 18 is installed. At this time, the flexible connecting cable 20 can be connected to the circuit board 18, and the CCS module is assembled.

[0041] Compared with the prior art, this utility model connects the aluminum busbar 19 to the circuit board 18 through the flexible connecting cable 20, which makes it easy to separate the aluminum busbar 19 from the circuit board 18. Through the cooperation of the limiting pressure plate 17, the L-shaped limiting plate 13, the threaded column 14 and other structures, the circuit board 18 can be disassembled and installed, thereby improving the flexibility of the CCS module, facilitating its maintenance, and reducing maintenance costs and complexity.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
