Specifically, as shown in fig. 1, the nickel plate 3 is used for connecting with an external automobile battery pack, and then is connected with the main circuit board 1 through the conducting wire 5, so that the purpose of detecting the performance of the automobile battery pack can be achieved through connecting the main circuit board 1 with an external detection device. The structure of the connecting wire 21 of this embodiment is as shown in fig. 1, and is preferably a flat flexible cable, which covers a plurality of wires 5 through two layers of insulating layers 4, and when the wires 5 are actually used, they can be bent or folded to facilitate connection with the nickel sheets 3, and the adjacent nickel sheets 3 are not easy to have a short circuit, and are also convenient to be connected with an external battery pack, as shown in fig. 1, the specific structure of this embodiment is not limited, as long as the function of connecting each wire 5 with a battery pack can be realized. Further, the radial cross section of the lead 5 of the present embodiment is circular or eccentric, such as a transverse oval or a vertical oval, as shown in fig. 7 to 9, which is not limited in the present embodiment.
The protection module 13 of this embodiment is a fuse protector 15, the fuse protector 15 is welded to the main circuit board 1, each conducting wire 5 is electrically connected to the fuse protector 15, as shown in fig. 1, this embodiment sets up a plurality of pads for welding the fuse protector 15 on the main circuit board 1, weld the fuse protector 15 on the main circuit board 1, each fuse protector 15 is electrically connected to a conducting wire 5, thereby when the power supply of the automobile battery pack is abnormal, the fuse protector 15 can disconnect the automobile battery pack from the main circuit board 1. The fuse protector 15 may be a fuse resistor or a fuse, as long as the fuse protection function is achieved. The present embodiment provides the fuse protector 15 independently on the main circuit board 1 so that the corresponding fuse protector 15 can be replaced when the fuse protector 15 is damaged, without affecting the use of the connection wires 21.
In the special-shaped flexible flat signal collecting line with replaceable protection components provided by this embodiment, as shown in fig. 11, the main circuit board 1 of this embodiment may be configured as a structure combining the PCB 19 and the FPC 20, and since the FPC 20 has the advantages of lightness, flexibility, and the like, the design combining the FPC with the PCB 19 is helpful to reduce the volume, weight, and the like of this embodiment compared with completely using the PCB 19, and may also be more flexible.
Specifically, in the prior art, as shown in fig. 10, by adopting the structural design of the PCB 19 and the complete FPC, the FPC flexible circuit board needs to design 21 lines of connecting wires, which is high in cost, and when a certain detecting element is damaged or a certain line on the board is damaged, the whole FPC needs to be replaced, and when the structure with the obstacle in fig. 10 is encountered, the structure of the FPC needs to be designed correspondingly, so that the structure meets different use environments, that is, when the FPC is applied to different automobile battery environments, the corresponding FPC needs to be matched, so that each FPC can only adapt to one use environment, and the practicability is relatively low.
In the present embodiment, the structure of pure FPC in the prior art is set as the structure of FPC plus flat connecting wires 21, as shown in fig. 11 and 12. That is to say, the PCB 19 and the FPC 20 at the front end can be arranged in a general design, and then the structure of the connecting wire 21 at the rear end is changed correspondingly according to the structure of the car battery pack in practical application, but the structure of the connecting wire 21 of the embodiment is simpler than the prior art in production mode, so even if the structure is modified in a bending manner according to different application environments, the structure is faster and simpler than the structure completely adopting the FPC, and the production cost is lower than the FPC, so that the structure has higher practicability.
Example two:

The fuse protector 15 may be a fuse resistor or a fuse, as long as the fuse protection function is achieved.
Specifically, in this embodiment, the fuse protector 15 is independently configured as a protection module 13, and is welded with the nickel sheet 3 and the lead 5 by using a welding method, so that firstly, the protection function of the fuse protector 15 can be achieved, and secondly, if one of the fuse protectors 15 is damaged, the protection module 13 where the fuse protector 15 is located can be detached and replaced, so that the protection module 13 can continue to perform the protection function, and the use of the connection line 21 of this embodiment is not affected.
As an embodiment of the present embodiment, the first pad 17 of the present embodiment may be designed in a rectangular shape as shown in fig. 3, so as to facilitate the bonding of the wire 5 to the first pad 17.
As another embodiment of this embodiment, the first pad 17 of this embodiment may also be provided in a cross shape as shown in fig. 2, and since the wire 5 may be folded or bent into a structure as shown in fig. 2 or fig. 4 in an actual design, the first pad 17 is provided in a cross shape, so that the first pad can be well contacted and welded with the first pad 17 in a cross shape regardless of the structure of the vertical and horizontal wire 5 in fig. 4, which helps to reduce the occurrence of false welding or cold welding.
Example three:
the present embodiment is different from the first and second embodiments in the arrangement of the protection module 13, as shown in fig. 5 and 6, and the third embodiment is combined with the first and second embodiments, and the fuse protector 15 is arranged on the main circuit board 1, and the fuse protector is not arranged on the protection circuit board 16, and the first pads 17 and the second pads 18 are directly connected together. Wherein the structure of the first pads 17 also includes a square shape and a cross shape.
