To this end, the present application provides a flat spring terminal, as shown in fig. 1 to 3, the flat spring terminal 3 in the embodiment of the present application includes a first clamping piece 31 and a second clamping piece 32 which are fixedly connected together at tail portions and are arranged in parallel, wherein:
The first clamping piece 31 is provided with a first elastic piece 33, and the first elastic piece 33 is bent towards the second clamping piece 32 to form a first clamping boss 331.
The second clamping piece 32 is provided with a second elastic piece 34, and the second elastic piece 34 is bent toward the first clamping piece 31 to form a second clamping protrusion 341. In particular, the second clamping protrusion 341 and the first clamping protrusion 331 are offset in the longitudinal direction (X-axis direction as shown in fig. 1) of the flat elastic terminal.
The flat elastic terminal 3 according to the embodiment of the present application performs elastic clamping connection to a target mating terminal (for example, a unipolar plate of a galvanic pile) through the first clamping protrusion 331 on the first elastic piece 33 and the second clamping protrusion 341 on the second elastic piece 34.
Since the first clamping protrusion 331 and the second clamping protrusion 341 are offset in the length direction of the flat elastic terminal. Therefore, the overall thickness of the flat spring terminal 3 of the present application can be reduced while maintaining the clamping force.
The flat elastic terminal 3 of the present application can realize elastic connection to a mating terminal such as a unipolar plate of a fuel cell.
Fig. 4 and 5 show a connection state of the flat elastic terminal 3 and the unipolar plate 101 of the stack 100 of the fuel cell in the embodiment of the present application. The galvanic pile 100 has several layers of monopole boards 101, gaps are formed between two adjacent layers of monopole boards 101, when the connection to a certain monopole board 101 needs to be implemented, the first clamping piece 31 and the second clamping piece 32 are aligned to the gaps on two sides of the monopole board 101 respectively, then the first clamping piece 31 and the second clamping piece 32 are synchronously inserted into the corresponding split gaps, and the first clamping protruding portion 331 on the first elastic piece 33 and the second clamping protruding portion 341 on the second elastic piece 34 can be elastically pressed on two side walls of the monopole board 101, so that the elastic connection to the monopole board 101 is implemented.

In addition, optionally, the first elastic check plate 313 and the second elastic check plate 323 may be integrally formed on the first clamping plate 31 and the second clamping plate 32, so that the elastic force of the first elastic check plate 313 and the second elastic check plate 323 may be further improved.
