Description

Technical Field

[0001] The present disclosure relates to the technical field of flexible flat cables, and in particular to a flexible flat cable used in a CCS module and a CCS module. Background Art

[0002] The battery module CCS is an electrical connection structure within the battery module. It integrates information collection components (flexible cables such as FPC and FFC), plastic structural components, aluminum bars and other components into a module and installs it in the battery module to achieve functions such as high-voltage series and parallel connection of battery cells, temperature sampling of the battery, voltage sampling of the battery cells and overcurrent fusing. It is part of the BMS battery management system. Due to the complex connection relationship between the internal structural components of the CCS module, the flexible cable often needs to be electrically connected one-to-many, that is, one end of the flexible cable is connected to one power supply component and the other end is connected to multiple power supplies. This requires that one end of the flexible cable needs to be torn open to form multiple connection ports. However, the structural design of traditional flexible cables has the problem of being difficult to tear open and easily damaging the wire layer when torn open.

[0003] In order to solve the above problems, a Chinese patent with application number CN202123144471.4 discloses a flexible flat cable that is easy to tear, including a flexible flat cable body, the flexible flat cable body including an upper insulating layer, a wire and a lower insulating layer, one end of the flexible flat cable body and located between two adjacent wires are provided with a tear line distributed along the length direction of the flexible flat cable body, which is used to tear the soft flat cable body, one end of the soft flat cable body and located on both sides of the tear line are respectively provided with a first splicing block and a second splicing block, and the first splicing block and the second splicing block are detachably connected.

[0004] However, the structural design of the above-mentioned flexible row connecting line has the following problems during use:

[0005] The above-mentioned flexible flat cable has an easy-tear wire distributed along the length direction of the flexible flat cable body between two adjacent wires, that is, when an external force acts on the easy-tear wire, the two adjacent wires are separated to form two connection ports. However, when the easy-tear wire is subjected to a large force, it is easy to cause the easy-tear wire to be torn for a long length, resulting in damage to the flexible flat cable body. At the same time, there is also a problem that the accuracy of the wire length obtained after the easy-tear wire is torn is not high.

[0006] Therefore, there is an urgent need for a flexible flat cable structure that can prevent the flexible flat cable from being damaged and has a high length accuracy after the wire is torn. Utility Model Content

[0007] The purpose of the present disclosure is to overcome the deficiencies in the prior art and to provide a flexible flat cable and a CCS module for use on a CCS module that prevents damage to the flexible flat cable and has a higher length accuracy after the wire is torn.

[0008] The purpose of this disclosure is achieved through the following technical solutions:

[0011] The flexible flat cable also includes a plurality of blocking protective members, which are spaced apart along the length direction of the insulating protective layer, and have different lengths. Each of the blocking protective members is respectively abutted against the corresponding tear line, so that when the insulating protective layer is torn along the tear line, conductor layers of different lengths are formed.

Furthermore, each barrier protection part is respectively in contact with the corresponding tearing line, and the position of the barrier protection part in the insulating protective layer can be adjusted to obtain a conductor layer of corresponding length, thereby improving the accuracy of the length of the conductor layer obtained after the insulating protective layer is torn.

[0032] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0033] like Figure 1 and Figure 2As shown, a flexible flat cable 10 for a CCS module in one embodiment includes a flexible flat cable body 100, an insulating protective layer 200 and a plurality of blocking protective members 300, wherein the flexible flat cable body 100 is connected to the insulating protective layer 200, and the flexible flat cable body 100 includes a plurality of spaced apart wire layers 110, both ends of each of the wire layers 110 are protruding from the insulating protective layer 200, a tearing gap is formed between two adjacent wire layers 110 along the length direction, the insulating protective layer 200 is provided with a tearing line 210 corresponding to the tearing gap, a plurality of the blocking protective members 300 are spaced apart along the length direction of the insulating protective layer 200, and the lengths of the plurality of the blocking protective members 300 are different, and each of the blocking protective members 300 is respectively in contact with the corresponding tearing line 210, so that when the insulating protective layer 200 is torn along the tearing line 210, the wire layers 110 of different lengths are formed.

[0034] In this embodiment, a plurality of conductor layers 110 are spaced apart and distributed inside the insulating protective layer 200, and both ends of each conductor layer 110 are protruded from the insulating protective layer 200, so that both ends of the conductor layer 110 are electrically connected to the power supply. Further, the insulating protective layer 200 is provided with a plurality of tear lines 210 along the length direction, each tear line 210 is used to obtain a conductor layer 110 of a corresponding length after tearing, and a blocking protective member 300 is provided at the tail of each tear line 210, and each blocking protective member 300 is set at a different length, and the blocking protective member 300 is connected to the surface of the insulating protective layer 200 by bonding, and when the tear line 210 is torn to the tail, it is blocked by the blocking protective member 300, that is, the tear line 210 cannot be torn further, thereby avoiding the problem of damage to the flexible flat cable body due to excessive tearing. Furthermore, the position where the barrier protection member 300 is bonded to the surface of the insulating protection layer 200 can be adjusted so that a conductor layer 110 of a corresponding length can be obtained after the tear line 210 is torn, thereby improving the accuracy of controlling the length of the conductor layer 110 .

[0035] In the flexible flat cable 10 used in the CCS module, a plurality of conductor layers 110 are spaced apart and distributed in the insulating protective layer 200, a tearing gap is formed between two adjacent conductor layers 110, the insulating protective layer 200 is provided with a tearing line 210 corresponding to the tearing gap, and a plurality of blocking protective members 300 of different lengths are spaced apart along the length direction of the insulating protective layer 200. When the insulating protective layer 200 is torn to a certain position along the tearing line 210, it is blocked by the blocking protective member 300, that is, it cannot be torn along the tearing line 210 further, thus avoiding the problem of damage to the flexible flat cable body 100 due to excessive tearing. Furthermore, each blocking protective member 300 is respectively in contact with the corresponding tearing line 210, and the position of the blocking protective member 300 in the insulating protective layer can be adjusted to obtain a conductor layer 110 of a corresponding length, thereby improving the accuracy of the length of the conductor layer 110 obtained after the insulating protective layer 200 is torn.

[0036] In one embodiment, the widths of the plurality of barrier protection members 300 are set to be the same, so that the overall structure of the flexible flat cable is more compact and the appearance is neater.

[0037] In one embodiment, the width of each of the blocking protective members 300 is 9 mm to 10 mm. In this embodiment, the width of the blocking protective member 300 is 10 mm.

[0038] In one embodiment, the barrier protection member 300 is a Mylar film barrier protection member 300. In this embodiment, the barrier protection member 300 is a transparent Mylar film, which is bonded to the surface of the insulating protective layer 200 and does not affect the appearance of the flexible flat cable. At the same time, the Mylar film also has high temperature resistance to adapt to the working environment of the flexible flat cable.

[0039] like Figure 2 As shown, in one embodiment, the length of the plurality of blocking protective members 300 gradually decreases along the length direction of the insulating protective layer 200. In this embodiment, the two ends of the wire layer 110 are respectively a first end and a second end, the first end is electrically connected to the power supply, and the second end needs to be torn along the tear line 210 to be electrically connected to another power supply, the length of the blocking protective member 300 close to the first end is the largest, and the length of the subsequent blocking protective member 300 gradually decreases, so that the blocking protective members 300 of different wire layers 110 will not interfere with each other when they are torn.

[0040] In one embodiment, the insulating protective layer 200 includes a first insulating layer and a second insulating layer connected to each other, the two sides of the conductive wire layer 110 are respectively connected to the first insulating layer and the second insulating layer, the tear line 210 includes a first tear line 210 unit and a second tear line 210 unit, the first insulating layer is formed with the first tear line 210 unit along the length direction, the second insulating layer is formed with the second tear line 210 unit along the length direction, and the first tear line 210 unit and the second tear line 210 unit are arranged correspondingly.

[0041] It can be understood that the first insulating layer and the second insulating layer are an integral injection molding structure, so that the middle part of the wire layer 110 is wrapped between the first insulating layer and the second insulating layer. When an external force acts on the first insulating layer and the second insulating layer, the first tear line 210 unit and the second tear line 210 unit are torn together to separate the two adjacent wire layers 110.

[0042] In one embodiment, a plurality of barrier protection members 300 are bonded to the surface of the first insulating layer. In this embodiment, the barrier protection members 300 are bonded to the surface of the first insulating layer by glue or PP glue, so that the barrier protection members 300 are fixed to the surface of the first insulating layer.

[0043] like Figure 2 As shown, in one embodiment, the surface of the first insulating layer is further provided with an identification area 400, and the identification area 400 is used for device scanning. It can be understood that the identification area 400 is a QR code, which contains product information of the flexible flat cable, such as production date, batch code, material type, etc., and the product information can be scanned by a mobile phone or other communication device, so that the user can better trace the product during use.

[0044] The present application also provides a CCS module, comprising the flexible flat cable 10 used on the CCS module as described in any of the above embodiments.

[0045] Compared with the prior art, the present invention has at least the following advantages:

[0046] In the flexible flat cable 10 used in the CCS module, a plurality of conductor layers 110 are spaced apart and distributed in the insulating protective layer 200, a tearing gap is formed between two adjacent conductor layers 110, the insulating protective layer 200 is provided with a tearing line 210 corresponding to the tearing gap, and a plurality of blocking protective members 300 of different lengths are spaced apart along the length direction of the insulating protective layer 200. When the insulating protective layer 200 is torn to a certain position along the tearing line 210, it is blocked by the blocking protective member 300, that is, it cannot be torn along the tearing line 210 further, thus avoiding the problem of damage to the flexible flat cable body 100 due to excessive tearing. Furthermore, each blocking protective member 300 is respectively in contact with the corresponding tearing line 210, and the position of the blocking protective member 300 in the insulating protective layer can be adjusted to obtain a conductor layer 110 of a corresponding length, thereby improving the accuracy of the length of the conductor layer 110 obtained after the insulating protective layer 200 is torn.

[0047] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be based on the attached claims.
