The opposite-inserting device according to any one of claims 1 to 6, wherein a guide post protrudes from one side of the second seat body facing the first seat body, and the first seat body is provided with a guide hole corresponding to the guide post; the height of the guide post relative to the surface of the second base body is higher than that of the second end conductive piece;

and in the process of inserting the female seat and the male plug in an opposite way, the guide column and the guide hole are used for assisting in aligning.

8. The opposite insertion device according to claim 7, wherein one end of the guide post, which is far away from the second seat body, is provided with a conical surface convex portion, and an edge of the guide hole, which is close to the guide post, is provided with a conical surface concave portion corresponding to the conical surface convex portion.

9. The opposite insertion device according to any one of claims 1 to 6, wherein a mounting portion for mounting the second end conductive member is provided at the center of the movable seat, and the second end conductive members are uniformly arranged in the mounting portion along a horizontal transverse direction or a horizontal longitudinal direction;

the second end conductive piece comprises a plurality of conductive monomers; at least part of the conductive monomers are arranged among the rest conductive monomers, and the current bearing capacity of the at least part of the conductive monomers is smaller than that of the rest conductive monomers.

10. A test system comprising a battery of a device under test, test equipment and an interposer device as claimed in any one of claims 1-9.
