Description

Technical Field

[0001] This utility model relates to energy storage battery connectors, and more particularly to an energy storage battery connector assembly for rapid positioning of ribbon cables. Background Technology

[0002] Traditional energy storage battery connectors mostly use a combination of distributed wires and pads with injection-molded plates, which has the following drawbacks:

[0003] The process is cumbersome, requiring each wire to be processed and manually soldered to the plate, resulting in low automation and high labor costs; it occupies a large space, making the wire harness bulky and increasing the module height, which is difficult to adapt to the needs of compact design; it lacks stability, and the wires are prone to loosening or poor contact, affecting electrical performance.

[0004] While existing technologies employ cabling solutions, they lack efficient positioning structures, resulting in inaccurate positioning of the sampling cables after cabling branching, low welding precision, and an inability to meet the requirements of automated production. Therefore, there is an urgent need for a connector solution that integrates rapid positioning functionality, has a compact structure, and is suitable for automated production. Utility Model Content

[0005] To address the shortcomings of the aforementioned technologies, this invention provides an energy storage battery connection assembly for rapid positioning of ribbon cables.

[0006] To solve the above technical problems, the technical solution adopted by this utility model is: a battery connection component for quick positioning of ribbon cables, including an injection-molded isolation plate and ribbon cables and pads mounted on the injection-molded isolation plate;

[0007] The injection-molded isolation plate is connected to guide grooves and fixing block assemblies;

[0008] Guide grooves are symmetrically distributed on the injection-molded isolation plate to guide the bending path of the sampling cable branching out from the wiring;

[0009] The fixing block assembly is located at the end of the guide groove to provide vertical restriction for the sampling cable. The sampling cable extends along the guide groove into the restriction area of ​​the fixing block assembly and connects downward to the bar plate.

[0010] Furthermore, the ribbon cable is a flexible flat cable, and the main body of the ribbon cable is fixed to the injection-molded isolation plate by positioning and fixing buckles. The sampling cable is formed by branching the ribbon cable and is connected to the main body of the ribbon cable by a perpendicular bend.

[0011] Furthermore, the sampling plates are positioned below the cable trays, with each sampling plate corresponding to a sampling cable. The injection-molded isolation plate has vertically protruding hot riveting posts on its surface at the corresponding positions of each sampling plate, and the sampling plates have hot riveting post holes that match the hot riveting posts.

[0012] Furthermore, the bar plate and the sampling cable are limited by a fixing block assembly, which consists of two spaced and oppositely bent blocks. The opening between the two spaced bent blocks is aligned with the guide groove. The bar plate and the sampling cable are electrically connected by laser welding within the limiting area formed by the fixing block assembly.

[0013] Furthermore, the guide groove of the injection-molded isolation plate is formed between two adjacent U-shaped groove structures to guide the bending path of the sampling cable.

[0014] Furthermore, the cable is equipped with an electrical signal interface for connecting to external data acquisition equipment.

[0015] Furthermore, the plate is equipped with a perforated design to allow sampling cables to pass.

[0016] This utility model provides an energy storage battery connection component for rapid positioning of ribbon cables. By deeply integrating the waist hole structure of the injection-molded isolation plate with the bending design of the ribbon cable, it solves the pain points of traditional energy storage connectors, which are cumbersome and reliant on manual labor. It is applicable to new energy vehicle battery systems and industrial energy storage equipment, and provides an efficient solution for high-precision and high-stability electrical connection requirements.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] This embodiment discloses an energy storage battery connector that combines a ribbon cable and an injection-molded separator plate, such as... Figure 1As shown, its core structure includes an injection-molded isolation plate 1, a ribbon cable 2, and a plate 3. Each component is assembled as a single unit through precision positioning and hot riveting. Specifically, the injection-molded isolation plate 1, as the main load-bearing substrate, is injection-molded from high-temperature resistant engineering plastic. Its surface integrates positioning and fixing buckles 4, guide grooves 5, fixing block assemblies 6, and hot riveting posts 7. The positioning and fixing buckles 4 are distributed on both sides of the injection-molded isolation plate 1 to fix the main body of the ribbon cable 2 and prevent lateral displacement. The guide grooves 5 are formed between two adjacent U-shaped groove structures and symmetrically distributed on the injection-molded isolation plate 1 to guide the bending path of the sampling cable 10 branching off from the ribbon cable 2. The fixing block assembly 6 is located at the end of the guide groove 5 to provide vertical limitation for the sampling cable 10, ensuring its precise alignment with the plate 3. The fixing block assembly consists of two spaced and opposing bending blocks, with the opening between the two spaced bending blocks aligned with the guide groove. The plate and the sampling cable are electrically connected by laser welding within the limiting area formed by the fixing block assembly. The hot riveting post 7 protrudes vertically from the surface of the injection-molded isolation plate 1 and is used to penetrate the hot riveting post hole 9 of the bar plate 3 to fix the bar plate 3 through the hot melt process.

[0024] like Figure 2 As shown, the ribbon cable 2 uses a flexible flat cable (FFC), with sampling cables 10 branching off from both sides. The ends of these cables integrate electrical signal interfaces 11 for connecting to external data acquisition equipment. Figure 3 As shown, the width of the main body of the ribbon cable 2 matches the positioning and fixing buckle 4 of the injection-molded isolation plate 1. The buckling ensures no offset. The sampling cables 10 branching off from both sides are bent perpendicularly to the main body of the ribbon cable and extend along the guide groove 5 to the area of ​​the fixing block assembly 6. Combined with... Figure 4 As shown, the plate 3 is a copper stamped part used for electrical series or parallel connection between battery cells. Its structural design includes a hot riveting post hole 9 that matches the hot riveting post 7, and a shaped hole 8 for avoiding the sampling cable 10. A welding area is formed within the range limited by the fixing block assembly 6 in the shaped hole 8.

[0025] During assembly, the battery pack 3 is first placed in the preset position on the injection-molded separator plate 1, and the hot-riveting post 7 passes through the hot-riveting post hole 9; then the cable 2 is fixed by the positioning and fixing buckle 4, and the sampling cable 10 is bent along the guide groove 5 to the area of ​​the fixing block assembly 6; the battery pack 3 is fixed and the cable 2 is pressed by the hot riveting process; finally, the sampling cable 10 and the battery pack 3 are laser welded within the limiting area of ​​the fixing block assembly 6 to complete a stable electrical connection. This solution significantly improves automation efficiency and connection reliability through the integrated positioning structure of the injection-molded separator plate, the flattened design of the cable, and the precise assembly process, and is suitable for battery systems of new energy vehicles and energy storage equipment.

[0026] After completing the above positioning, the injection-molded isolation plate 1, the cable 2, and the platen 3 are integrated into a single structure using a hot riveting process. Since the sampling cable 10 is positioned within the designated area of ​​the platen 3 by the guide groove 5 and the fixing block assembly 6, a high-precision electrical connection between the sampling cable 10 and the platen 3 can be achieved directly through laser welding, eliminating the need for additional positioning devices. Compared to traditional technologies, the core advantage of this solution lies in its higher degree of automation, simplified structure, and integrated functions.

[0027] First, the flattened design of the ribbon cable 2 significantly reduces wiring space, while the sampling cable 10 formed by its bends can directly extend to the area of ​​the electrode plate 3, eliminating the need for additional wires or adapters in traditional solutions. Therefore, this connector has the advantages of fewer parts, simple structure, and ease of manufacturing and assembly. Second, the structure on the injection-molded separator plate 1 is tightly connected and cooperates with each component, resulting in high overall structural strength of the connector. In summary, the specific implementation of this utility model successfully solves the defects of high cost and poor automation of traditional energy storage battery connectors through innovative structural design and process integration. Its core structure lies in the pre-set waist holes in the injection-molded separator plate, which facilitates the positioning of the sampling cable and enables high-precision welding to the electrode plate, improving the automation of the production process. Its core value lies in the deep integration of the electrical performance advantages of the ribbon cable with the adhesive function of the hot-press film, which simplifies the production process and improves the adaptability of the product. This technical solution is not only applicable to energy storage battery systems for new energy vehicles, but can also be extended to fields such as energy storage equipment, providing an efficient solution for high-precision and high-stability electrical connection requirements.
