As shown in fig. 1 and fig. 2a and 2b, the inner conductor 1 may be implemented as a pogo pin or other elastic contact, and under the action of an external force, specifically, a pressing action, the top end of the inner conductor 1 can be compressed along the axial direction, and an electrical connection with a corresponding circuit board is implemented.

Further, the tip of the outer conductor 2, in particular the tip of the first outer conductor 21, forms an inwardly turned spring 211, the spring 211 may have a compression in the axial direction and a compression in the radially inward direction under the action of an external force, in particular a pressing action.
