The present invention relates to a
coupling device, in particular to a waterproof
coupling device, comprising an inserter, a coupler, a sealing cover, a data bridge module, a live wire bridge module and a neutral bridge module, and the inserter is provided with a live wire insert The input terminal, the
neutral line insertion terminal, the data
insertion terminal and the insulating layer covering the outer surface of the live wire
insertion terminal, the
neutral line insertion terminal and the data insertion terminal; the coupler is divided into a
coupling chamber and a sealed cavity The external matching thread outside the chamber and the sealing chamber, the coupling chamber and the sealing chamber are separated by a
barrier layer provided in the coupler, and the
barrier layer is provided with a live wire coupling sleeve, a neutral wire coupling sleeve, a data
Coupling sleeve, data through hole, live line through hole,
neutral line through hole and sliding sleeve cooperate with the extension sleeve; the invention can be used immediately after insertion, one step in place, with anti-shock design; has multiple waterproof effects, can be used in water, and adopts
Modular design for easy repair and replacement parts.
