Particularly, the size of above-mentioned angle a is 90 °.

From the description stated the utility model structure, the utility model tool has the following advantages:

One, the utility model, comprise the single-phase two pole pins of band or the base of single-phase three pole pins, lid and rotor, rotor comprise be provided with two jacks disk, rotating shaft and for hindering the insulation shell fragment of rotor turns.During use, the plug slice of another plug is stretched in two jacks of this plug, inconsistent with insulation shell fragment, make the generation deformation of insulation shell fragment and be separated from each other with the draw-in groove of base, thus making rotor rotatable; Now metal clips does not contact with plug slice, and another plug is in non-"on" position; After plug slice inserts completely, overcome torsion spring resistance, rotary connector and rotor, until plug slice is stuck in the recess of metal clips, now rotor and plug cannot be rotated further the inhibition of plug slice because of metal clips, and another plug is in "on" position; After pulling out another plug, rotor returns back to initial position because of the active force of torsion spring, until insulation shell fragment and draw-in groove fasten mutually, is retightened by rotor.Visible, external object cannot directly contact with metal clips after inserting jack, prevents electric shock accidents.Another plug rotates and gets an electric shock injured when the design that could be energized can avoid child to play, and drastically increases fail safe; Rotor only all with during exact separation could be rotated at two insulation shell fragments in the design of insulation shell fragment, and when the jack of this plug is left unused, rotor cannot arbitrarily rotate, and improves fail safe further.

Two, in the utility model, one is formed for accommodating the annular gathering sill of plug slice between rotor and base, annular gathering sill can limit the rotational trajectory of plug slice, ensures plug slice and coordinating more accurately between insulation shell fragment, metal clips, improves the reliability of this plug.

Three, in the utility model, the upper surface of disk is provided with an annular table terrace, and the upper surface of disk is mutually concordant with the upper surface of lid.The design of annular table terrace allows rotor better be located between base and lid, prevents rotor from sliding; Can prevent dust from entering socket inside by the space between disk and lid simultaneously.

Four, in the utility model, when plug slice is stuck in the recess of metal clips, the sidewall of the insulation lower end of shell fragment and metal clips is inconsistent and be right against recess.By the effect of shell fragment of insulating, plug slice is more firmly stuck in the recess of metal clips, and cooperatively interacting by insulation shell fragment and metal clips, better plug slice can be clamped, depart from from the jack of this plug to prevent another plug.

Five, in the utility model, the width of metal clips is 0.3cm ~ 0.5cm, and the lower surface of metal clips contacts with base.Like this, could contact with metal clips in the jack that the plug slice of another plug needs almost to insert completely this plug, prevent people from getting an electric shock, improve the fail safe of this plug.
