As the core part of the power battery safety monitoring center, the CCS component usually includes isolation brackets, FPCs, conductive bars, nickel collection sheets and other components, among which the FPCs and conductive bars are fixedly placed on the isolation brackets.

[0003] In the prior art, a plurality of hot melt columns are usually arranged on the isolation bracket for positioning and limiting. Through holes matching the hot melt columns are arranged on the FPC and the conductive bar. The FPC and the conductive bar are placed on the corresponding hot melt columns, and then the FPC and the conductive bar are fixed on the plastic bracket through the hot riveting process. Refer to Chinese invention patent application CN117464310A, which discloses an automatic assembly process for CCS integrated busbars, and the assembly process is: 1) aluminum bar loading; 2) aluminum bar overall hot riveting; 3) FPCA loading: 4) FPCA single-point hot riveting. However, due to the long length of the FPC, it is necessary to arrange a plurality of hot melt columns along the length direction of the FPC to better fix the FPC, and the hot melt columns on the FPC need single-point hot riveting. Therefore, it takes a long time to hot-rivet the FPC hot melt columns, which seriously affects the work efficiency and increases the cost.

[0004] Therefore, in view of the above-mentioned technical problems, the utility model proposes a blister limiting bracket and a CCS component and a battery module having the bracket. Utility Model Content

[0005] The utility model aims to solve the technical problem that the CCS component in the prior art uses hot riveting to fix the FPC, which leads to long time consumption and low working efficiency, and proposes a blister limiting bracket and a CCS component and a battery module with the bracket.

[0006] In order to achieve the above-mentioned purpose, on the one hand, the utility model provides a blister limit bracket, which includes an FPC main body fixing area, a first side edge and a second side edge are respectively arranged on both sides of the FPC main body fixing area, a first conductive bar installation area is arranged outside the first side edge and a second conductive bar installation area is arranged outside the second side edge, a plurality of first bosses are arranged in sequence between the first side edge and the first conductive bar installation area, and a plurality of second bosses are arranged in sequence between the second side edge and the second conductive bar installation area, each of the first bosses is provided with a first limit plate extending toward the FPC main body fixing area, each of the second bosses is provided with a second limit plate extending toward the FPC main body fixing area, an insertion gap for inserting an external FPC body is arranged between the first limit plate and the second limit plate and the FPC main body fixing area respectively, and the first limit plate and the second limit plate are staggered with each other on a plane parallel to the FPC main body fixing area.

[0007] Furthermore, through holes are formed in the FPC body fixing area at positions corresponding to the first limiting piece and the second limiting piece respectively.

[0008] Furthermore, the overlapping length of the first limiting piece and the second limiting piece on the external FPC body is 5-15 mm, and the overlapping length does not exceed 1 / 3 of the width of the external FPC body.

[0009] Furthermore, the distance between the central axes of the adjacent first limiting pieces and the second limiting pieces is 25-40 mm.

[0010] Furthermore, a plurality of conductive bar installation slots are sequentially arranged in the first conductive bar installation area and the second conductive bar installation area, and at least one first limiting column is arranged in each of the conductive bar installation slots.

[0011] Furthermore, an escape space for accommodating the first boss or the second boss is provided between adjacent conductive bar mounting slots on the same side, and the escape space is located at one end of the conductive bar mounting slot close to the FPC body fixing area.

[0012] Furthermore, an FPC board end fixing area is provided at one end of the FPC main body fixing area, and at least one second limiting column is provided on the FPC board end fixing area.

[0013] Furthermore, there are two second limiting posts, and the two second limiting posts are diagonally arranged.

[0015] On the other hand, the utility model further provides a battery module, which includes the above-mentioned CCS component.

[0016] The beneficial effects of the utility model are as follows:

[0017] When the FPC is to be fixed in the blister limit frame, it is only necessary to insert the FPC body into the insertion gap between the first limit plate, the second limit plate and the fixed area of ​​the FPC body. Compared with the single-point hot riveting method using hot melt columns in the prior art, it effectively saves the time for fixing the FPC, improves work efficiency and reduces production costs; and because the first limit plate and the second limit plate are staggered up and down in a plane parallel to the fixed area of ​​the FPC body, they can generate pressing pressure on multiple positions on both sides of the FPC body respectively, and the pressing pressure on both sides is staggered along the length direction of the FPC body, so that the FPC body can be well fixed and the FPC body can be effectively prevented from warping, thereby ensuring a stable connection between the FPC body and the collection nickel sheet, and further ensuring the reliability of the CCS assembly.

DETAILED DESCRIPTION

[0024] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0025] like Figures 1 to 4 As shown, the utility model provides a blister limit bracket, which includes an FPC main body fixing area 1, and the two sides of the FPC main body fixing area 1 are respectively provided with a first side 11 and a second side 12, the first side 11 is provided with a first conductive bar installation area 21 outside, and the second side 12 is provided with a second conductive bar installation area 22 outside, and a plurality of first bosses 31 are sequentially provided between the first side 11 and the first conductive bar installation area 21, and a plurality of first bosses 31 are sequentially provided between the second side 12 and the second conductive bar installation area 22. There are a plurality of second bosses 32, each of which is provided with a first limiting piece 41 extending toward the FPC body fixing area 1, and each of which is provided with a second limiting piece 42 extending toward the FPC body fixing area 1. A plug-in gap 5 for inserting an external FPC body is provided between the first limiting piece 41 and the second limiting piece 42 and the FPC body fixing area 1, respectively. The first limiting piece 41 and the second limiting piece 42 are staggered with each other on a plane parallel to the FPC body fixing area 1.

[0026] In actual use, when the FPC needs to be fixed in the blister limit frame, it is only necessary to insert the FPC body into the insertion gap 5 between the first limit plate 41, the second limit plate 42 and the FPC body fixing area 1. Specifically, the height of the insertion gap 5 is 0.3-0.5mm, which is compatible with the thickness of the FPC body 7. Since the first limiting piece 41 and the second limiting piece 42 have a certain elasticity, they can generate a certain pressing force on the FPC body 7 located therebelow, and the first limiting piece 41 and the second limiting piece 42 are staggered up and down in a plane parallel to the FPC body fixing area 1, and can generate pressing force on multiple positions on both sides of the FPC body 7 respectively, and the pressing forces on both sides are staggered along the length direction of the FPC body 7, so that the FPC body 7 can be well fixed and the FPC body can be effectively prevented from warping, thereby ensuring a stable connection between the FPC body 7 and the collection nickel sheet 9, and further ensuring the reliability of the CCS assembly; and the method of fixing with the staggered first limiting piece 41 and the second limiting piece 42 effectively improves work efficiency, saves time for fixing the FPC, and reduces costs compared with the method of single-point hot riveting with hot melt columns in the prior art.

[0027] Furthermore, through holes 13 are formed in the FPC body fixing area 1 at positions corresponding to the first limiting piece 41 and the second limiting piece 42 .

[0028] Furthermore, the overlap length L of the first limiting piece 41 and the second limiting piece 42 overlapped on the external FPC body is 5-15 mm, and the overlap length L does not exceed 1 / 3 of the width of the external FPC body. Through the above arrangement, the pressing force of the first limiting piece 41 and the second limiting piece 42 on the FPC body can be ensured, and the first limiting piece 41 and the second limiting piece 42 can be prevented from affecting other structures and functions of the FPC body.

[0029] Furthermore, the distance T between the central axes of the adjacent first limiting pieces 41 and second limiting pieces 42 is 25-40 mm. Through the above arrangement, the number of the first limiting pieces 41 and the second limiting pieces 42 can be reasonably set to ensure the pressing force on the FPC body.

[0030] Further, a plurality of conductive bar installation slots 23 are sequentially provided in the first conductive bar installation area 21 and the second conductive bar installation area 22, and at least one first limiting column 24 is provided in each conductive bar installation slot 23. Preferably, two first limiting columns 24 are provided in each conductive bar installation slot 23. In this embodiment, the conductive bar 8 can be well limited and fixed by the conductive bar installation slot 23 and the first limiting column 24, thereby ensuring the positioning accuracy of the conductive bar.

[0031] Furthermore, an escape space for accommodating the first boss 31 or the second boss 32 is provided between the adjacent conductive bar mounting grooves 23 on the same side, and the escape space is located at one end of the conductive bar mounting groove 23 close to the FPC body fixing area 1. Specifically, at least one of the two adjacent conductive bar mounting grooves 23 on the same side is set in a "convex" shape to form an escape space at one end close to the FPC body fixing area 1 for accommodating the first boss 31 and the second boss 32, so that the overall structure of the CCS assembly is more compact, and a first limiting piece 41 and a second limiting piece 42 are provided at the position of the escape space, and a collection nickel sheet 9 is provided at the protruding part of the "convex" shape, so that the first limiting piece 41 and the collection nickel sheet 9 and the second limiting piece 42 and the collection nickel sheet 9 are arranged in sequence and spaced apart, so as to avoid the first limiting piece 41 and the second limiting piece 42 from interfering with the setting of the collection nickel sheet 9.

[0032] Furthermore, an FPC board end fixing area 6 is provided at one end of the FPC body fixing area 1, and at least one second limiting column 61 is provided on the FPC board end fixing area 6. Preferably, there are two second limiting columns 61, and the two second limiting columns 61 are diagonally arranged. In this embodiment, since the size of the FPC board end 10 is different from that of the FPC body 7, it is not convenient to use the same first limiting plate 41 and second limiting plate 42 to fix the FPC board end 10. Therefore, an FPC board end fixing area 6 adapted to the size of the FPC board end 10 is additionally provided, and the FPC board end 10 is stably limited by two second limiting columns 61 arranged diagonally.

[0033] On the other hand, the utility model also provides a CCS component, the CCS component includes any of the above-mentioned blister limit brackets, the FPC body 7 is installed in the FPC body fixing area 1, and a plurality of connecting pieces 71 are arranged on both sides of the FPC body 7 in sequence, the first limiting piece 41 and the second limiting piece 42 avoid the connecting piece 71 and overlap the two sides above the FPC body 7, and the first conductive bar installation area 21 and the second conductive bar installation area 22 are respectively arranged in sequence. A plurality of conductive bars 8 are arranged in each of the first conductive bar installation area 21 and the second conductive bar installation area 22, and each of the connecting pieces 71 is connected to the corresponding conductive bar 8 through the collection nickel sheet 9. It can be understood that the number of conductive bars 8 matches the number of collection nickel sheets 9.

[0034] In this embodiment, the first limiting piece 41 and the second limiting piece 42 are overlapped on both sides of the FPC body 7 by staggered arrangement up and down, so as to generate pressing force on multiple positions on both sides of the FPC body 7 respectively, and the pressing force on both sides is staggered along the length direction of the FPC body 7, so that the FPC body 7 can be well fixed and the FPC body can be effectively prevented from warping, thereby ensuring the stable connection between the FPC body 7 and the collection nickel sheet 9, and further ensuring the reliability of the CCS component; and the first limiting piece 41 and the second limiting piece 42 are arranged to avoid the connecting piece 71. Since the connecting piece 7 and the conductive bar 8 need to be connected through the collection nickel sheet 9, such an arrangement can make the first limiting piece 41 and the collection nickel sheet 9 and the second limiting piece 42 and the collection nickel sheet 9 be arranged in sequence, thereby avoiding the first limiting piece 41 and the second limiting piece 42 from interfering with the setting of the collection nickel sheet 9, and making the structure of the CCS component more compact.

[0035] On the other hand, the utility model further provides a battery module, which includes the above-mentioned CCS component.

[0036] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
