When the driving device 500 drives the pushing assembly 400 to move, so that the pushing assembly 400 is separated from the collar assembly 300, the collar assembly 300 is in a release state, the conductive outer ring assembly 310 and the conductive inner ring assembly 320 are reset to the initial position, the conductive inner ring assembly 320 does not press the conductive outer ring assembly 310 any more, at least part of the outer peripheral wall of the conductive outer ring assembly 310 and the inner peripheral wall of the second accommodating cavity 210 are arranged at intervals, at least part of the inner peripheral wall of the conductive inner ring assembly 320 and the male terminal conductive terminal 21 are arranged at intervals, so as to release the male terminal conductive terminal 21, at this time, the male terminal conductive terminal 21 is easily taken out from the collar assembly 300 and is easily inserted again, when the male terminal 21 is inserted or taken out, a plating layer on the male terminal is not easily rubbed with the collar assembly 300 to generate abrasion, which is beneficial to improving the conductivity of the male terminal 21.

When the inner conductive rings 321 and the outer conductive rings 311 are disposed in the sequence ABABAB, the driving device 500 drives the pushing assembly 400 to push the collar assembly 300, the pushing assembly 400 pushes the adjacent inner conductive rings 321 to inwardly contract until the inner conductive rings are abutted to the male terminal conductive terminals 21 inserted into the collar assembly 300, the pushed inner conductive rings 321 continue to push the adjacent outer conductive rings 311, the outer conductive rings 311 outwardly expand to be abutted to the inner peripheral wall of the second receiving cavity 210, the pushed outer conductive rings 311 continue to push the adjacent inner conductive rings 321, the inner conductive rings 321 inwardly contract to be abutted to the male terminal conductive terminals 21, the inner conductive rings 321 continue to push the adjacent outer conductive rings 311 outwardly expand to be abutted to the inner peripheral wall of the second receiving cavity 210, and the remaining inner conductive rings 321 and outer conductive rings 311 sequentially push in the above manner, which is not described herein.

The radial multi-contact shunt of the conductive connecting terminal 200 has strong current carrying capacity, and can carry current from tens of amperes to hundreds of amperes or even thousands of amperes. By making the radial line contact and the point contact, even the surface contact, of the conductive connection terminal 200 coexist, the current carrying capacity of the conductive connection terminal 200 and the female terminal connector 10 is greatly improved. The number of the inner conductive rings 321 and the outer conductive rings 311 can be properly matched based on the conductive connection terminals 200, so as to achieve functional diversity of the product.

Alternatively, the projections on the axial vertical planes of the inner conductive ring 321 and the outer conductive ring 311 may be a fracture 330 circle, a regular fracture 330 polygon or an irregular fracture 330 polygon, and the shapes of the inner conductive ring 321 and the outer conductive ring 311 may be selected according to the shape of the second receiving cavity 210.
