Abstract
The utility model relates to a rotary contact type safety plug and a socket. The utility model is characterized in that a gear engagement device is arranged in the plug. Thus, an insertion sheet can rotate in a self mode. A socket medium fire and the contact sheet of a zero line are sealed in an insulation groove. When the insertion sheet is inserted into a jack and is rotated into a certain angle, the insertion sheet is contacted with the contact sheet through a contact hole. At ordinary time, the contact hole is sealed by a seal seat. Even if a child finger or a metal object is inserted into the jack, electric shock accident can not occur. The utility model which can be widely used for families and industries can be universally used for plugs and sockets of multi-phase of two-phase, three-phase, four-phase, etc.
Description
The utility model relates to a kind of rotary contact type safety plug and socket.
General family, socket for industry, the contact of its fire, zero line exposes, and causes electric shock accidents easily.By retrieval, patent ZL87216795 proposes, and special-shaped plug is inserted in the jack, by the rotation whole plug inserted sheet is contacted with contact, and energized is to reach purpose of safety.But this method can only be used for two phase plugs, and is powerless for three-phase, four phase plugs.
The purpose of this utility model provides a kind of plug that makes can be around the device that self rotates, and it can effectively make two-phase, three-phase, four equate that heterogeneous plugs contact with the socket contact sheet rotation, and reaches safe and reliable purpose.
The purpose of this utility model is achieved in that a plug totally is divided into bayonet cap, plug body two parts, and two parts link to each other by bayonet socket, so bayonet cap can rotate relatively.Embed a gear ring on bayonet cap, tab end portion has gear, and by the engagement of gear and gear ring, the relative rotation of bayonet cap just can drive inserted sheet and rotate around self.Contact is encapsulated in and has flat band breach and touch in the separate slot in hole in the socket, touches the sealed seat sealing in hole at ordinary times.Inserted sheet is designed to key shape, and inserted sheet inserts jack, depresses seal receptacle, exposes and touches the hole, and rotation inserted sheet certain angle, inserted sheet just can touch the hole breach and contact energized with contact by touching the hole and snapping in.
The utility model can rotate inserted sheet around self because utilize Principles of Gear Connection, equates heterogeneous plug so can be used in three-phase, four, and versatility is wide; Because contact is encapsulated in and has in the separate slot that touches the hole in the socket, and touch the sealed seat sealing in hole at ordinary times, so safer.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the profile according to the rotary contact type 3-phase plug that the utility model proposes.
Fig. 2 is the engagement figure of the gear ring that embeds on the gear of tab end portion and the bayonet cap.
Fig. 3,4,5 is the schematic diagram of three parts of plug body.
Fig. 6 is the outline drawing of socket.
Fig. 7 is the part sectioned view of socket.
Describe the details and the working condition of the concrete device that the utility model proposes in detail below in conjunction with legend.
This device comprises rotation plug (Fig. 1) and socket (Fig. 6) two parts.
Plug is assembled with a support spring (3) by bayonet socket mutually by bayonet cap (1) and plug body (6,7,8).By fastening being assembled into one of screw (4), power line is entered by hole (9) plug body by three parts (6,7,8), inserts binding post (5) respectively.Bayonet cap (1) is gone up and is embedded a gear ring (11), and the end of inserted sheet (10) has gear (2) to mesh in gear ring (11).
Socket is made up of socket cover (17), socket (16).On cover the jack (18) of three special shapes.The contact (12) of fire, zero line is encapsulated in respectively in the separate slot (19), and that opens on the separate slot that a flat has a breach touches hole (15), and on separate slot (19) wall, introduced by hole (20) and be connected on the contact (12) by power line by spring compression for contact (12).
During energized, the inserted sheet of plug (10) is inserted in the jack (18) of socket, press down plug, seal receptacle (position 5) moves down, and exposes and touches hole (15), rotary connector lid (1); By the engagement of gear ring (11) and gear (2), drive the inserted sheet rotation, the sweep of inserted sheet is entered touch hole (15); And snap in breach, link to each other with contact (12).When cutting off the electricity supply, press rightabout, turn bayonet cap (1), the sealed seat of inserted sheet (10) (14) ejects automatically.
As be used for two-pin plug, and plug body can change two parts symmetrical into to be formed, and inserted sheet moves to center line; As be used for four plugs, can on the basis of 3-phase plug, increase by an inserted sheet and get final product.The quantity of receptacle sockets and structure can correspondingly be adjusted.
Claims (5)
1, rotary contact type safety plug and socket, the plug that can make inserted sheet self rotation is arranged and have the socket that touches the hole, it is characterized in that bayonet cap (1), plug body (6 that plug is connected by bayonet socket, 7,8) form, the gears engaged device is arranged in the plug, can make inserted sheet (10) rotation, contact in the socket (12) is packaged in and has in the separate slot that touches hole (15), and touching the hole can sealed seat (14) sealing.
2,, it is characterized in that bayonet cap (1) and plug body (6,7,8) have bayonet arrangement, and link to each other with support spring (3) by bayonet socket according to right 1 described plug and socket.
3,, it is characterized in that going up embedding one gear ring (11) at bayonet cap (1) according to right 1 described plug and socket.
4, according to right 1 described plug and socket, it is characterized in that there is a gear (2) end of inserted sheet (10), the other end has a crooked contact.
5, according to right 1 described plug and socket, it is characterized in that contact in the socket (12) is encapsulated in the separate slot (19), open the notched hole (15) of touching of a flat on the separate slot.
