The conductive piece 3 has a first position during installation and a second position where it is moved by the lock cylinder 2 and connected to the conductive element 6 for ignition. The advantages of this invention are that the connector assembly, with its conductive element directly connected to the electric vehicle wiring harness, allows the lock cylinder to move the conductive element, causing the transmission element to engage or disengage with the conductive element, thus achieving circuit connection or disconnection. This avoids the need for soldering connecting wires and reduces the number of components. This invention also has advantages such as simple structure, convenient assembly, reliable operation, and long service life.

[0026] This utility model also includes a connector 7 connected to the insert housing 5. The conductive component 6 includes a conductive part 61 for connecting to the conductive sheet 3 and a plug-in part 62 for connecting to the electric vehicle wiring harness.

More specifically, the insert housing 5 has an annular plate 57, which forms the slot 55, and the annular plate 57 has a notch 571 at the pin 56 to facilitate the deformation of the pin 56. The pin can reliably and quickly plug and unplug into existing electric vehicle wiring harnesses, has a simple structure, and is connected to the electric vehicle wiring harness through the conductive element within the slot.

[0032] The insert 5 is connected to the housing 1 via a locking block 58 and a locking hole 11. The lock cylinder 2 is linked to the electric transmission plate 3 via a rotor component 8. The rotor component 8 is provided with a rotating bead 9 that forms a stop with the inner wall of the housing 1. Specifically, the lock cylinder driving the electric transmission plate through the rotor component can be achieved using existing technology.
