Abstract
The utility model relates to a coupler which is free from the limitation of directions and can randomly rotate. The utility model is composed of a coupler head and a coupler seat which respectively present a concave convex concentric ring, wherein, a ground rod and a metallic conduction ring are arranged on the coupler head; a ground lead rod and a metal conduction rod are arranged in a groove of the coupler seat. The coupler is suitable for the switch-on and the switch-off of various split electric appliances and is free from the limitation of the directions; the utility model can randomly rotate and can also keep a favorable contact.
Description
The utility model relates to a kind of power on/off device, and especially a kind of no orientation limits rotatable coupler.
At present, known switching electricity except outside the Pass, generally be to adopt the plug and the socket of two pin or tripod to realize, because plug and socket are subjected to the restriction in orientation, then can't meet the demands to some electrical equipment,, adopt prior art can't solve especially particularly to split type electric food warmer.
The purpose of this utility model provides a kind of coupler, and it can not only make up, separate, and any in the horizontal direction rotation does not influence coupler contact performance and can be multi-joint yet.
The purpose of this utility model is achieved in that this coupler mainly is made up of coupler head that respectively is the concave-convex concentric ring and coupler seat.Center at the coupler head is provided with earth rod, is provided with the metallic conduction circle on each protruding circle, and is provided with leading foot at an end of earth rod and metallic conduction circle, and in order to connect lead, the surface of each metallic conduction circle is through silver-plated processing, to strengthen conductive effect.Be provided with flexible ground connection freely and draw rod and many metal conductive bar in the groove of coupler seat, ground connection is drawn rod and of metal conductive bar respectively is provided with silver contact; The other end that ground connection is drawn rod and metal conductive bar respectively is provided with spring, when the coupler head cooperates with the coupler seat, this spring is in compressive state, make ground connection draw rod and every metal conductive bar is subjected to certain expansive force, with keep ground connection draw on excellent and each metal conductive bar silver contact all the time with the coupler head on earth rod and metallic conduction circle well contact.When coupler seat in a state of nature the time, the silver contact that ground connection is drawn rod is higher than the silver contact of each metal conductive bar, thereby has guaranteed " first ground connection, back energising; Outage earlier, the back is liftoff " safety requirements.Metallic conduction circle on the coupler head can be provided with simply connected, duplex and multi-joint according to different purposes settings with metal conductive bar on the coupler seat.Because coupler head and coupler seat adopt the manufacturing of concave-convex concentric ring structure, reach and be not subjected to the orientation to limit any rotation also to keep the purpose that well contacts.
Because adopt such scheme, the utility model can rotate arbitrarily in use, not limited by the orientation, and simple in structure, contact performance is good, long service life.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the profile of the utility model embodiment.
Fig. 2 is the floor map of coupler head embodiment.
Fig. 3 is the floor map of coupler seat embodiment.
1. coupler heads, 2. earth rods, 3. metallic conduction circles, 4. screws, 5. leading foots, 6. silver contacts, 7. springs, 8. ground connection are drawn excellent 9. jump rings, 10. coupler seats, 11. metal conductive bar among the figure
Press shown in Fig. 1,2,3, the utility model adopts insulating material to make, and it is mainly by respectively being concave-convex concentric ring coupler head (1) and coupler seat (10) is formed.Be provided with earth rod (2) in the center of coupler head (1), be provided with metallic conduction circle (3) on each protruding circle, this metallic conduction circle bottom surface is a plane of a loop.End at earth rod (2) and metallic conduction circle (3) is provided with lead connection leading foot (5), and is fixed on the coupler head (1) with screw (4), and the surface of each metallic conduction circle (3) is through silver-plated processing, to strengthen conductive effect.Be provided with ground connection in the center of coupler seat (10) and draw rod (8), and in its groove, be provided with flexible many metal conductive bar (11) freely.Ground connection is drawn rod (8) and metal conductive bar (11) one and respectively is provided with silver contact (6), respectively is provided with a spring (7) in the other end, and fixing with jump ring (9).When coupler head (1) and coupler seat (10) when cooperating, this spring (7) is in compressive state, make ground connection draw rod (8) and each metal conductive bar (11) is subjected to certain expansive force, with keep ground connection draw on rod (8) and each metal conductive bar (11) silver contact (6) all the time with coupler head (1) on earth rod (2) and metallic conduction circle (3) well contact.When coupler seat (10) in a state of nature the time, the silver contact (6) that ground connection is drawn rod (8) is higher than the silver contact (6) of each metal conductive bar (11), thereby has guaranteed first ground connection, the requirement that the back is liftoff.Because coupler head (1) and coupler seat (10) adopt the manufacturing of concave-convex concentric ring structure, reach and be not subjected to the orientation to limit any rotation also to keep excellent contact.
