The invention discloses a
tail end joint of an
alternating current charging gun. The problems that an existing
alternating current charging gun is poor in
tail end waterproof effect and circuit line fixing effect are solved. The
tail end joint comprises an outer
pipe and an inner
pipe. The outer
pipe comprises a connecting section and a squeezing section, the inner wall of the connecting section is provided with an internal thread, and the inner
diameter of the squeezing section is smaller than that of the connecting section. The inner pipe comprises a pipe core and a pipe mat, the pipe core comprises a locating ring and a
deformation ring which are formed into a whole, the pipe mat comprises a
gasket and spacers evenly formed at the end of the
gasket, the pipe core is sleeved with the pipe mat, the
gasket corresponds to the locating ring to form a locating section, the spacers correspond to the
deformation ring to form a deformation section, the inner
diameter of the deformation section is gradually reduced from the side corresponding to the locating section to the side opposite to the locating section, and the outer
diameter of the side, opposite to the locating section, of the deformation section is larger than the inner diameter of the squeezing section. An effective waterproof effect on the tail end of the
alternating current charging gun can be achieved, and cables can beeffectively fixed as well.
