As preferably, described folder spring structure is made monolithic construction by the phosphorus copper plate punching press of excellent spring, and its front portion is that the folder spring to the external symmetry reflexed constitutes receiving electrode, and its rear portion is the binding post that is provided with buckle that can the wrapped folder cable core.Utilize buckle that cable core is pinched on described binding post to realize cable core and to press from both sides fixedlying connected of spring structure.
As preferably, described folder spring structure is provided with two row folder springs arranged side by side; Described lock ring cover front end is provided with two metal plate springs of two groups of symmetries side by side, and two metal plate springs withstand on the back waist location of two row folder springs respectively.
As preferably, described lock ring cover rear end is arranged with the shell fragment of two outside reflexeds, and the afterbody of two shell fragments is against the bottom of two draw-in grooves that are provided with in the plug casing respectively.It can prevent that the folder spring structure that is connected with cable core from being deviate from by the cable core tractive.
As preferably, the tail structure of described plug casing lengthening as the tail of lizard, be tapered and be provided with thread groove.This structure can effectively prevent stress raisers, has improved the pliability of afterbody, prolongs power line useful life.
As preferably, respectively be provided with a convex tendon outside the both sides of described plug casing; This convex tendon can play guide effect in the time of can matching for plug insertion socket with the groove on being located at socket, and prevents that in the use of electric connector the relative socket of plug from waving loosening phenomenon, further improves the connection reliability of plug and socket male part.
The beneficial effects of the utility model are:
1. reduce the folder spring structure probability that makes moist, improve the electric connector safety performance;
2. the folder spring makes the reed applying of folder spring tightr by means of the elastic force of metal plate spring, and resilience force and durability are better, are electrically connected more reliable;
3. plug is provided with the locking device that is connected with socket, this locking device structure compactness, and locking is reliable, and is easy to use;
4. housing tail structure lengthening is tapered and is provided with thread groove, has improved the pliability of afterbody, prolongs power line useful life.
