Chinese invention patent CN101060210A discloses a kind of key-type safety plug and socket thereof, but the firewire electrode of the firewire electrode of its plug and zero wire electrode and socket and zero wire electrode coordinate and bad, be easy to loose contact, and it does not solve the problem that plug comes off from socket.
Utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, it is high that the purpose of this utility model is to provide a kind of fail safe, the safety socket that the reliable and plug of contact can not come off and plug thereof.
In order to solve the problem, the utility model is by the following technical solutions: a kind of safety socket, comprise jack body and be arranged on zero wire electrode, firewire electrode and the ground wire electrode on jack body, described jack body is provided with cylindrical receptacle, the openend of described cylindrical receptacle is axially provided with protrusion chute, is provided with and protrudes that chute communicates and coaxial with cylindrical receptacle annular groove I on the top of cylindrical receptacle; The middle part of described cylindrical receptacle is provided with annular groove II; Described ground wire electrode is arranged on the bottom of cylindrical receptacle, and described firewire electrode is arranged in annular groove II, and described zero wire electrode is arranged on the upper surface of annular groove I; The bottom of described cylindrical receptacle is provided with spring, and ground wire electrode is fixed on spring upper end.
Further, in described annular groove II, be provided with spring, firewire electrode is fixed on spring; Firewire electrode is arc, and two ends are concordant with the surface of cylindrical receptacle, and centre is protruded to cylindrical receptacle.
With the plug that above-mentioned safety socket is supporting, described plug is cylindrical, and its top is provided with handheld terminal, the bottom of described plug is provided with ground wire, and intermediate position is provided with ring-shaped fire the end of a thread, at an upper portion thereof, be positioned at below described handheld terminal and arrange zero line head, zero line head is the projection protruded.Further, the side of described handheld terminal is provided with anti-slip veins.
The beneficial effects of the utility model are:
1, its socket and plug design are key-type, by live wire, zero line and ground wire layering, and use safety.
2, rationally, coordinate ingenious, contact is good, can not loose contact for the electrode on plug and the electrode structural designs on socket.
3, the zero line head on plug can be stuck in socket after insertion socket, prevents plug from falling.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described further:
Fig. 1 is the overall structure schematic diagram of the utility model socket;
Fig. 2 is that structural representation cut open by socket of the present utility model;
Fig. 3 is plug construction schematic diagram of the present utility model.
Embodiment
As depicted in figs. 1 and 2, the cylindrical receptacle 2 that safety socket of the present utility model comprises jack body 1 and is arranged on jack body, is provided with zero wire electrode 3, firewire electrode 4 and ground wire electrode 5 in cylindrical receptacle.
The openend of described cylindrical receptacle 2 is axially provided with and protrudes chute 21, is provided with and protrudes that chute 21 communicates and coaxial with cylindrical receptacle 2 annular groove I 22 on the top of cylindrical receptacle 2.The middle part of described cylindrical receptacle 2 is provided with annular groove II 23, further, spring 7 is provided with in described annular groove II 23, firewire electrode 4 is fixed on spring 7, firewire electrode 4 is arranged in annular groove II 23, it can be one piece of circular ring metal conducting strip, also can be some pieces of metallic conduction sheets.The longitudinal profile of firewire electrode 4 is arc, and two ends are concordant with the surface of cylindrical receptacle 2, and centre is protruded to cylindrical receptacle 2.Described ground wire electrode 5 is arranged on the bottom of cylindrical receptacle 2, and the bottom of described cylindrical receptacle 2 is provided with spring 6, and ground wire electrode 5 is fixed on spring 6 upper end.Described firewire electrode 4 is arranged in annular groove II 23, and described zero wire electrode 3 is arranged on the upper surface of annular groove I 22.Power line on socket is laid, here no longer describes in detail, in Fig. 2, also depict schematic diagram.
As shown in Figure 3, the plug 8 that a kind of and above-mentioned safety socket is supporting, described plug 8 is cylindrical, and its top is provided with handheld terminal 81, in order to prevent sliding when rotary connector, the side of described handheld terminal 81 is provided with anti-slip veins.The bottom of described plug 8 is provided with ground wire 82, and intermediate position is provided with ring-shaped fire the end of a thread 83, and the diameter of ring-shaped fire the end of a thread 83 is slightly less than the diameter of cylindrical receptacle.On plug 8 top, be positioned at below described handheld terminal and arrange zero line head 84, zero line head is the projection protruded, and the openend of cylindrical receptacle 2 is axially provided with and protrudes chute 21 for the design of zero line head.Conducting strip is set at the upper surface of zero line head 84, matches with the zero wire electrode 3 of annular groove I 22 upper surface.The lateral wall of ring-shaped fire the end of a thread 83 arranges conducting strip, coordinates with firewire electrode 4 in annular groove II 23.
During use, protrusion chute 21 on zero line head 84 alignment socket 1, then plug 8 is inserted, ground wire 82 bottom plug 8 contacts with ground wire electrode 5, after in zero line head 84 slideway annular groove I 22, rotate plug 8, make zero line head 84 away from protrusion chute 21, plug 8 by jack-up, makes zero line head 84 only match with the zero wire electrode 3 of annular groove I 23 upper surface under the restoring force of spring 6.While pressing down plug 8, ring-shaped fire the end of a thread 83 is extruding firewire electrode 4 inwardly, under the active force of spring 7, and firewire electrode 4 and ring-shaped fire the end of a thread 83 close contact.
