[0016] The utility model will be further explained in detail in combination with the drawings and specific embodiments.

[0017] As Figures 1-2 The embodiment relates to the FPC temperature sampling NTC fixed structure of a power battery CCS assembly, and the FPC temperature sampling NTC fixed structure comprises a blister isolation plate 1 connected with an FPC assembly 4, a temperature sampling NTC 7 is punched on one side of the blister isolation plate 1 and is connected with the FPC assembly 4 in electricity through the foam 8.

[0018] The blister isolation plate 1 has a thickness and forms a first end face 9 and a second end face 10.

[0019] The size of the configuration groove 2 is matched with the foam 8, in actual operation, the foam 8 can be selected or cut according to the size of the configuration groove 2, in order to simplify the structure and make the FPC assembly 4 pass through, a reserved hole 3 is formed on one side of the configuration groove 2.

[0020] The FPC assembly 4 comprises a main body and a pin 5, and a bend is formed between the main body and the pin 5 of the FPC assembly 4, the design of the bend facilitates the outward extension of the pin 5.

[0021] On this basis, the main body of the FPC assembly 4 is connected on one side of the first end face 9, the connection between the FPC assembly 4 and the blister isolation plate 1 is prior art, the pin 5 of the FPC assembly 4 is led to one side of the second end face 10 through the reserved hole 3, that is, as Figure 1 As shown in the figure, the pin 5 of the FPC assembly 4 is led to one side of the groove bottom surface of the configuration groove 2 through the reserved hole 3, in this process, it can be seen that the bend between the main body and the pin 5 of the FPC assembly 4 plays a good transition role, and the structure is prevented from being bad from the structure.

[0022] The reserved space 6 is formed between the pin 5 and the configuration groove 2, which is the difference in space thickness, and is also the space thickness difference formed by leveling the reserved space 6, so the thickness of the reserved space 6 is matched with the thickness of the foam 8. In the actual processing process, the thickness of the reserved space 6 is actively matched by cutting or selecting the foam 8, so as to form a stable plane structure.
