Abstract

The utility model discloses a single-phase multifunctional plug belonging to an electrical apparatus element. The utility model comprises a shell and an upper cover, wherein, the upper cover is provided with three round holes which are arranged at the three vertexes of a triangular; the two underlying round holes are provided with a positioning concave groove; each round hole is provided with a metal cylinder which can rotate in the round hole; the upper end of each metal cylinder is provided with a pin; the pin at the upper end can rotate by 90 DEG in a vertical plane. The utility model which can be matched with a two-hole or a three-hole socket respectively has the advantage of safe and convenient use.

Description

Single-phase multifunctional plug

The utility model belongs to a kind of electrical equipment original paper, particularly a kind of single-phase multifunctional plug.

Existing plug can be divided into two kinds of two pins and three pins substantially, two pins need the use that matches of the socket in two holes, three pins then need the socket in three holes to be used with it, if there is not corresponding socket will feel inconvenient in use; When pin is three and socket when being two holes, people can be habitually with one of them pin bending, and inconvenience is also dangerous.In addition, different electrical equipment needs different plugs, and when the plug conversion, original plug will be useless, causes waste.

The purpose of this utility model is to overcome the existing single in the use defective of plug, and a kind of single-phase multifunctional plug that can match with two holes or Three-hole socket respectively is provided.

The utility model is achieved in that it has a housing and a loam cake, on cover circular hole or two circular holes that are arranged in parallel that three triangularities are arranged, the circular hole place that is arranged in parallel two of loam cake upper surfaces is processed with detent; A metal cartridge that can rotate in the hole all is installed in each circular hole, and all there is a pin upper end of each metal cartridge.

Advantage of the present utility model is and can be complementary with two holes or Three-hole socket respectively.Because metal cartridge can rotate in the hole, can make pin form the angle that the jack angle with socket adapts, adapting to the needs of different sockets, thereby safety, convenience when using.

Fig. 1 is a schematic appearance of the present utility model;

Fig. 2 is a front view of the present utility model;

Fig. 3 is an A-A cutaway view of the present utility model;

Fig. 4 is a B-B cutaway view of the present utility model.

Fig. 5 is the schematic diagram that the place, two holes that covers on the utility model to become to be arranged in parallel processes scalloped recess.

Provide embodiment of the present utility model below in conjunction with accompanying drawing.

As shown in drawings: the utility model has the housing 1 of an injection mo(u)lding, is connected with a loam cake 2 by screw on housing 1, forms an entrance hole 11 between the afterbody of housing 1 and loam cake 2.On loam cake 2, be processed with circular hole that three triangularities arrange and one and the crossing rectangular recess 12 of the circular hole of upper end.Cross circular hole at two circular hole places of loam cake 2 lower ends and also be processed with two detents that intersect with circular hole respectively, one of them detent is parallel with groove 12, and another detent becomes 30 to spend angles with outside.Also can not process into the groove of 30 degree angles, directly processing central angle is the fan-shaped detent of 30 degree.Said fan-shaped detent can be two relative detents, also can be that a central angle is the scalloped recess of 30 degree.The metal cartridge 6 that a lower end is processed with internal thread hole and can rotates in the hole is installed in the circular hole of upper end, be processed with a groove in the upper end of metal cartridge 6, in groove, be connected with a pin 4 by pin, pin 4 can rotate around pin, when turning to 90 reliable pins 4 when spending and cylinder 6 formed shoulders location, submerge when spending in the groove 12 of loam cake 2 when turning to 0.Side surface at said cylinder 6 is processed with an annular groove, a spring card 5 that plays position-limiting action is installed in the annular groove, also be processed with a internal thread hole in metal cartridge 6 side surface lower ends and intersect, be used for the small sircle hole used by electric wire, in the internal thread hole of metal cartridge 6 lower ends, be equipped with one and compress the screw 7 that electric wire is used with metal cartridge 6 lower ends.In the circular hole that two one-tenth of loam cake 2 lower ends are arranged in parallel, be separately installed with a upper end and have pin 3, the lower end is processed with the metal cartridge 13 of internal thread hole, said cylinder 13 also can rotate in circular hole, be processed with an annular groove in the side surface bottom of metal cartridge 13, a spring card 10 is installed in the annular groove, also be processed with in metal cartridge 13 side surface lower ends one by electric wire with and the small sircle hole that intersects with metal cartridge 13 lower end internal thread holes, in the internal thread hole of metal cartridge 13 lower ends, be used for compressing the screw 9 that electric wire is used by being threaded one.Outer surface at metal cartridge 13 is set with a back-moving spring 8, and back-moving spring 8 lower ends withstand on the spring card 10.

At first electric wire is stretched into from housing 1 and loam cake 2 formed entrance holes 11 during use, and then with every wire respectively the entrance hole on

metal cartridge

6 and 13 stretch into and with screw in compression on metal cartridge, with screw loam cake 2 is fixed on the housing 1 at last.When using Three-hole socket, the pin of upper end can be forwarded to 90 degree, again two pins of lower end slightly upwards be mentioned and rotate 30 degree and put into detent and get final product as need; As the need two hole socket, the pin 4 of upper end can be changeed sinking in the rectangular recess 12 of loam cake 2, then two pins 3 of lower end are returned to original position and get final product.

Claims

1, a kind of single-phase multifunctional plug comprises housing, loam cake, on cover and be processed with three triangularities and arrange or two circular holes that are arranged in parallel, it is characterized in that: cover two circular hole places that are arranged in parallel and be processed with detent last; The metal cartridge that can rotate in circular hole is installed in said circular hole, and the upper end of metal cartridge all is equipped with pin.
