The flexible connection 43 is a helical connection and includes substantially two turns of the helix.

In addition, in the embodiment according to the present disclosure, the longitudinal deformation portion 5211 has a substantially circular shape, which is capable of being elastically deformed in a longitudinal direction parallel to the longitudinal axis of the second electrical connection member 50, so that it is possible to accommodate manufacturing, mounting errors of the respective devices, and relative movement between the respective devices due to impact, vibration, or the like during use. As a possible embodiment, the longitudinal deformation portion 5211 is formed by notching a substantially middle position of the second elastic bent portion 521 by punching or the like, and bending two legs separated by the notch into substantially semicircular shapes in opposite directions, respectively.
It should be understood that although the second elastic bent portions 521 of the two adjacent second electrical connection parts 50 are staggered with each other in the embodiments shown in fig. 8, 9 and 9A, the second end portions 52 of the two adjacent second electrical connection parts 50 may not be staggered with each other according to the present disclosure.

In addition, in one embodiment, a plurality of protruding portions 33 are disposed on the outer side of the base 30, and the protruding portions 33 are located between two adjacent elastic bending portions 63 of the elastic connecting piece 60. Specifically, as shown in fig. 8, the elastic connecting piece 60 includes 6 sets of elastic bent portions 63, each set of elastic bent portions 63 includes 4 elastic bent portions, and the protruding portion 33 is clamped between the elastic bent portions 63 of adjacent sets.

Specifically, as shown in fig. 10, the first electrical connection member 40 and the elastic connection piece 60 are used to electrically connect and fix the base 30 to the circuit board 20 in such a manner that the base 30 moves in multiple directions relative to the circuit board 20 (downward arrows show the direction of fastening force), thereby crimping the second electrical connection members 50 arranged in two rows onto the conductive portions 22 of the circuit board 20 and causing the longitudinal deformation portions 5211 of the second electrical connection members 50 to be compressed and deformed, so that reliable electrical contact of the second electrical connection members 50 with the conductive portions 22 of the circuit board 20 can be maintained even when the base 30 moves away from the circuit board 30 due to vibration, impact, or the like.
In one embodiment according to the present disclosure, the surface of the base 30 adjacent to the circuit board 20 is spaced a distance from the circuit board 20 such that the base 30 "floats" above the circuit board 20, thereby enabling the base 30 to move in a direction towards the circuit board 20 and in a direction away from the circuit board 20 while maintaining proper electrical connections between the various components. That is, the base 30 of the electrical connection assembly 10 according to the present disclosure is capable of moving relative to the circuit board 20 in various directions parallel to the circuit board 20 and in directions perpendicular to the circuit board 20 while maintaining a proper electrical connection between the electrical connection assembly 10 and the circuit board 20.
