Through the corresponding structural arrangement of the male and female connectors, the locking structure is externally mounted. The spring-loaded and snap-locking mechanisms on the male and female ends cooperate to achieve a reliable locking function. Slots and guide ribs on the male plug and female socket ensure accurate and smooth mating of the male and female ends. The cooperation of the anti-misalignment ribs and anti-misalignment grooves effectively prevents assembly errors. The sealing ring meets IPX7 waterproof performance. The guide plate and ramp restrict and... The protective latches feature a guide structure that slowly lifts the male latch during mating, guiding it into the female latch. When locked in place, the female latch engages with the male latch, providing a locking function. Tactile feedback is provided upon successful assembly to prevent improper installation. Pressing the unlock button on the male latch lifts it, separating it from the female latch and unlocking the device. A limiting protrusion on the male plug prevents over-pressure during unlocking, providing a locking and unlocking protection function and improving the tactile feel during actual use.
