[0034] 5、The insertion guide block provides auxiliary guiding function for the insertion process, ensuring the accuracy and smoothness of the insertion. The symmetrical guide block design helps the male plug and the electrical docking socket to be self-adaptively aligned, preventing the deviation of the docking angle. The arrow-shaped design at the front end of the insertion plate helps to quickly position the insertion plate during the docking process. The unique shape reduces the resistance when the male plug is inserted, while preventing the uneven force on the insertion plate from causing jamming or damage.

[0035] 6、The mounting cover is fixed on the structural profile of the automatic threading machine head by bolts, providing a stable foundation support. The fixed docking seat provides a stable installation platform for the electrical docking plug, ensuring that it can accurately align with the electrical docking socket of the female plug.

[0037] 8. By aligning the insertion guide post with the center hole of the insertion guide block, automatic guidance is achieved during the insertion process, improving docking accuracy. The use of guide wheels ensures the smooth introduction of the male connector during the insertion process, avoiding shaking or offset during insertion and increasing docking stability. A retaining ring is installed on one side of the guide wheel to provide additional fixing force, preventing loosening or falling off due to vibration or external force during the insertion process, thus improving the safety of the mechanical connection. Precise docking and stable connection effectively reduce electrical faults caused by poor contact or misalignment, such as signal loss or short circuit.

[0038] 9. The self-locking fixing seat provides a stable docking position, ensuring connection stability and reducing operational errors caused by loosening or misalignment. The guide slot and locking pin move closer to each other and achieve precise alignment during docking, ensuring high docking accuracy. The sliding fit between the locking jaws and the guide slot enables precise guidance and locking of the locking pin, effectively avoiding misalignment or insertion failure. The arc-shaped locking jaws can slide to insert the locking pin and, together with the guide slot, firmly lock the locking pin, effectively improving locking stability and preventing loosening. The tension spring effectively tightens the locking jaws and locks them onto the locking pin. Attached Figure Description
