Description

TECHNICAL FIELD

[0001] The utility model relates to CCS integrated busbar manufacturing technical field especially a CCS integrated busbar binding tool. BACKGROUND

[0002] The main application fields of CCS integrated busbar include new energy vehicles, energy storage devices, power grid energy storage, smart home and the like. The CCS integrated busbar is an electrical connection structure in a battery module, which integrates information acquisition components (flexible wire harnesses, FPCs, FFCs and the like), insulation supports, busbars and the like into a module, and is installed in the battery module to realize functions such as high-voltage series and parallel connection of battery cells, temperature sampling of batteries, voltage sampling of battery cells and overcurrent fusing.

[0003] In the assembly stage, each busbar needs to be electrically connected with the flexible wire harness. In order to ensure the regularity of the arrangement of the flexible wire harness and to save the trouble of subsequent secondary binding and lashing, a series of threading holes for the flexible wire harness to pass through are formed on the insulation support along the length direction. In view of the current workshop situation, when the worker performs the arrangement operation on the flexible wire harness, in order to smoothly pass through and wind around the threading hole, the insulation support needs to be repeatedly turned circumferentially, and the insulation support needs to be turned circumferentially once after each threading operation. Such operation, the working strength of the worker is extremely large, the total threading time is relatively long, and it becomes the bottleneck of the process rhythm. In addition, because the insulation support needs to be frequently turned, the flexible wire harness is easily entangled, and the worker needs to spend time and effort to comb. Therefore, it is urgent for technical personnel to solve the above problems. UTILITY MODEL CONTENTS

[0004] Therefore, the utility model designers, in view of the above existing problems and defects, collect relevant data, through the evaluation and consideration of many parties, and through the continuous experiment and modification of the technical personnel engaged in this industry for many years of research and development experience, finally lead to the emergence of the CCS integrated busbar binding tool.

[0005] In order to solve the above technical problems, the utility model relates to a CCS integrated busbar binding tool, and the CCS integrated busbar includes an insulating support, a busbar and a signal acquisition flexible wire harness. The busbar is fixed to the insulating support by hot pressing or riveting process. The signal acquisition flexible wire harness is wired along the length direction of the insulating support, and is sequentially electrically connected to the busbars on both sides through the threading holes. A series of positioning holes are formed on the insulating support and arranged along the length direction. The CCS integrated busbar binding tool includes a base plate, a threading guide plate and a positioning pin assembly. A plurality of threading guide plates are linearly arranged along the length direction of the base plate and fixed to the base plate. Threading guide grooves are formed on the threading guide plates. A plurality of positioning pin assemblies are linearly arranged along the length direction of the base plate and inserted into the base plate. The plurality of positioning pin assemblies are coordinated with the positioning holes to position the CCS integrated busbar relative to the CCS integrated busbar binding tool, and the threading guide grooves are one-to-one corresponding to the threading holes.

[0006] As a further improvement of the disclosed technical scheme, a plurality of sink grooves are formed on the base plate to accommodate the threading guide plates and match the shapes of the threading guide plates.

[0007] As a further improvement of the disclosed technical scheme, the positioning pin assembly has the function of pressing and fixing the threading guide plate. The bottom wall of the sink groove is extended downward to form an installation hole for the positioning pin assembly, and the threading guide plate has a through hole for the positioning pin assembly to pass through.

[0008] As a further improvement of the disclosed technical scheme, the threading guide groove has a "boat shape" formed by a plurality of arc curves with different curvature radii.

[0009] As a further improvement of the disclosed technical scheme, the threading guide groove has a high dimensional accuracy of IT6 level and a surface roughness value of less than or equal to 3.2 microns.

[0010] In actual application, when the CCS integrated busbar needs to be bound, the CCS integrated busbar binding tool is placed on the workbench, and then the CCS integrated busbar to be bound is placed on the CCS integrated busbar binding tool. The positioning pin assembly and the positioning hole are coordinated to guide the relative position of the CCS integrated busbar to be bound during the placing process, so that the threading hole and the threading guide groove are kept in alignment after the placing is completed. After the flexible wire harness is inserted into one of the threading holes, it can be automatically inserted into the adjacent threading hole under the guidance of the threading guide groove.

[0011] According to the on-site worker operation feedback, the CCS integrated busbar binding tool disclosed by the utility model can at least achieve the following beneficial technical effects, specifically:

[0012] 1) In the whole process of implementing the flexible wire harness collecting threading process, the CCS integrated busbar is always kept in the flat laying state, and the worker does not need to turn the CCS integrated busbar around, so that the total time for performing the flexible wire harness collecting threading operation can be greatly reduced, and the labor intensity of the worker is effectively reduced.

[0013] 2) Also thanks to the fact that the CCS integrated busbar does not need to be turned around, the phenomenon of mutual entanglement of the collected flexible wire harnesses is completely eliminated from the source, and a large amount of combing time and combing workload is saved.

DETAILED DESCRIPTION

[0029] In the description of the utility model, it is understood that the terms "left", "right", "front", "back", "up", "down" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0030] In the field of new energy vehicles and energy storage, CCS integrated busbars are widely used in battery modules to realize high-voltage series and parallel connection of batteries and acquisition of information such as temperature and voltage, and provide important data for BMS systems. As shown in Figure 2 , the CCS integrated busbar 1 is mainly composed of an insulating support 11, a converging busbar 12 and a signal acquisition flexible wire harness 13. Among them, the converging busbar 12 is arranged along the length direction of the insulating support 11, and is fixed with the insulating support 11 by hot pressing or riveting process. The signal acquisition flexible wire harness 13 is wired along the length direction of the insulating support 11, and is wound through the threading hole formed on the insulating support 11 to sequentially electrically connect the converging busbars 12 located on the front and rear sides thereof (as shown in Figure 3 , 4 ).

[0031] The utility model discloses a CCS integrated busbar binding tool, which belongs to the technical field of CCS integrated busbar binding tool. Figure 5 The CCS integrated busbar binding tool 2 is mainly composed of a base plate 21, a threading guide plate 22 and a positioning pin assembly 23. The plurality of threading guide plates 22 are linearly arranged along the length direction of the base plate 21 and are fixed to the base plate 21. Figure 7 As shown in the drawings, a plurality of sink grooves 211 are formed on the base plate 21 to accommodate the threading guide plates 22. Figure 6 、 8 As shown in the drawings, a plurality of sink grooves 211 are formed on the base plate 21 to accommodate the threading guide plates 22. Figure 3 、 4 As shown in the drawings, a plurality of sink grooves 211 are formed on the base plate 21 to accommodate the threading guide plates 22. Figure 12 、 13 As shown in the drawings, a plurality of sink grooves 211 are formed on the base plate 21 to accommodate the threading guide plates 22.

[0032] As shown in the drawings, a plurality of sink grooves 211 are formed on the base plate 21 to accommodate the threading guide plates 22. Figure 1 As shown in the drawings, a plurality of sink grooves 211 are formed on the base plate 21 to accommodate the threading guide plates 22. Figure 12 、 13 As shown in the drawings, a plurality of sink grooves 211 are formed on the base plate 21 to accommodate the threading guide plates 22.

[0033] By adopting the technical scheme, on one hand, during the whole process of the threading process of the flexible wire harness 13, the CCS integrated busbar 1 is always kept in the flat and laid state, and the worker does not need to turn the CCS integrated busbar 1 circumferentially, so that the total time for performing the threading operation of the flexible wire harness 13 is greatly reduced, and the labor intensity of the worker is effectively reduced; on the other hand, also thanks to the characteristic that the CCS integrated busbar 1 does not need to be turned circumferentially, the occurrence of the mutual entanglement of the flexible wire harness 13 is completely eliminated from the source, and a large amount of combing time and combing workload is saved.

[0034] Thanks to the design concept that the threading guide plate 22 is semi-submerged to be fixed to the base plate 21, the threading guide plate 22 has good position stability after being assembled, and even when subjected to excessive external force, the relative position and azimuth angle remain unchanged. Furthermore, the working section of the CCS integrated busbar threading tool 2 presents a low-high-ground state along the rear-to-front direction, so as to match the shape of the bottom of the CCS integrated busbar 1, and ensure that the CCS integrated busbar 1 is in good contact with the CCS integrated busbar threading tool 2 after being laid, which is beneficial to the smooth entry of the flexible wire harness 13 into the adjacent threading hole 111 through the threading guide groove 221.

[0035] It can also be clearly known from the Figures 9-11 that the positioning pin assembly 23 has the functions of pressing and fixing the threading guide plate 22. The positioning pin assembly 23 is composed of a screw and an internally threaded cylindrical positioning pin. As shown in the Figure 7 , the bottom wall of the sinking groove 211 is further extended downward to form a mounting hole 212 for the screw, and on the other hand, the threading guide plate 22 is provided with a through hole 222 (as shown in the Figure 8 ) for the screw to pass through freely. When the internally threaded cylindrical positioning pin is pre-tightened, the threading guide plate 22 is locked due to the pressing force from the internally threaded cylindrical positioning pin.

[0036] As shown in the Figure 6 , 8 , the threading guide groove 221 presents a “boat shape” and is formed by a plurality of arc curves with different curvature radii. In this way, the threading guide groove 221 has excellent threading guiding function, and effectively avoids the occurrence of the threading process interruption phenomenon caused by the jamming of the flexible wire harness 13.

[0037] In order to further reduce the motion resistance of the flexible wire harness 13 during the threading process in the threading guide groove 221, the forming precision of the threading guide groove 221 needs to be controlled in actual design, specifically as follows: the forming dimensional precision of the threading guide groove 221 is higher than IT6 level, and the surface roughness value is ≤3.2 μm.

[0038] The above description of disclosed embodiments enables one of ordinary skill in the art to make or use the application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
