Embodiment
For setting forth the thought and the purpose of the utility model, will combine accompanying drawing and specific embodiment that the utility model is done further explanation below.
See also Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, Fig. 1 is the decomposition texture sketch map of the utility model electrical connector plug; Fig. 2 is the cutaway view of the utility model electrical connector plug; Fig. 3 is the decomposition texture sketch map of the utility model electric connector socket; Fig. 4 is the cutaway view of the utility model electric connector socket.The utility model provides a kind of three-start screw and connects electric connector fast, comprises plug and socket, and plug wherein is made up of through back-up ring 10 is spacing coupling nut 5 and plug casing 2; Plug casing 2 arranged outside have shading ring 1, shading ring 1 be fixedly connected with plug casing 2 through the draw-in groove on the plug casing 2; Also be provided with ratchet reed 4 between plug casing 2 and the coupling nut 5, plug casing 2 is fixedly connected through ratchet reed 4 and rivet 3 with coupling nut 5; Be provided with insulator 7 and plug grommet 8 behind insulator 6 before the plug, the plug in the said plug casing 2, before the said plug behind insulator 6, the plug insulator 7 and plug grommet 8 internal fixation plug contact 9 is arranged.
Socket by the socket grommet 12 in Socket casing 16, locking nut 19 and setting and the Socket casing 16, socket after before the insulator 13, socket insulator 14 and interface sealing body 15 constitute; Be provided with socket contact 11 in the insulator 14 before insulator 13 and the socket behind said socket grommet 12, the socket; Said plug is corresponding to be connected with socket, and plug contact 9 and the 11 corresponding contacts of socket contact; Locking nut 19 is connected with Socket casing 16 through interfacial seal circle 17, O-ring seals 18.
