DETAILED DESCRIPTION
[0018] Clearly, the described embodiments are merely part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.
[0019] Please refer to Figs. 1-3 An embodiment provided by the present application:
[0020] The three-section hollow butt-joint waterproof connector includes a middle connector 16 in the middle, a first connector 17 and a second connector 18 connected with the middle connector 16, and an outer shell middle section 5 of the middle connector 16 is connected with the first connector 17 and the second connector 18 in an interference fit, and the interference fit part is fixedly connected through a connector 6, and the outer shell A 19 is fixedly connected with the first connector 17 and the second connector 18 through a sealing ring C 15 at both ends.
