Embodiment
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the embodiment of the present invention and accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described.It should be noted that, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment
Refer to Fig. 1, the invention discloses a kind of safety electric plug, comprise front plug 1 and rear plug 2;
Front plug 1 comprises first plug body 3, conduction tongue 4, conducting ring 7, conductive reed 13 and the first annular permanent magnet 12; Conduction tongue 4 is located at the front of the first plug body 3; The center, the back side of the first plug body 3 is provided with a line receptacle 5, is arranged with the neutral receptacle 6 of one annular outside line receptacle 5; Within conducting ring 7 is embedded in neutral receptacle 6 and with conduction tongue 4 zero line side be electrically connected; Conductive reed 13 is located at line receptacle 5 inside and is electrically connected with the live wire end of conduction tongue 4; First annular permanent magnet 12 is located at the inside of the first plug body 3, is positioned at the periphery of neutral receptacle 6;
Rear plug 2 comprises second plug body 8, live wire tongue 9, zero line tongue 10 and the second annular permanent magnet 12; Second plug body 8 back side is connected with wire; Live wire tongue 9 is located at the positive Middle face of the second plug body 8; Ringwise, zero line tongue 10 is located at the periphery of live wire tongue 9 to zero line tongue 10; Second annular permanent magnet 12 is located at the inside of the second plug body 8, is positioned at the periphery of zero line tongue 10, the second annular permanent magnet 12 contrary with the magnetic pole of the first annular permanent magnet 12 opposite side;
Live wire tongue 9 is plugged among line receptacle 5, and zero line tongue 10 is plugged among neutral receptacle 6.
Plug of the prior art is unitary design, and direct and socket is plugged in together use, and grafting is comparatively tight, once electric wire is stumbled to by the foot of people, easily makes electric wire rupture, and produces Danger Electric shock risk.Also be easier to people is stumbled to, injury human body simultaneously.
Operation principle of the present invention is: plug design becomes split type structure, is formed by connecting by front plug 1 and rear plug 2.Engaged by the magnetic force of the first permanent magnet with the second permanent magnet between front plug 1 with rear plug 2, as long as outside has enough pulling force that both can be made to be separated and power-off.Front plug 1 is plugged on socket, identical with general plug using method.The live wire end of conduction tongue 4 is connected with conductive reed 13, then through live wire tongue 9 delivered current, the zero line side of conduction tongue 4 is connected with conducting ring 7, then through zero line tongue 10 delivered current, forms the complete circuit that a zero line is communicated with live wire thus.But when being subject to External Force Acting, the front plug 1 only connected by magnetic force can be separated easily with rear plug 2, and so electric wire is just not easy to trip people, is also not easy fracture and causes Danger Electric shock risk.
As preferably, the length of described live wire tongue 9 is less than 3mm, and the length of described zero line tongue 10 is less than 3mm, and the diameter of described line receptacle 5 is less than 3mm, and the width of described neutral receptacle 6 is less than 3mm.When front plug 1 is separated with rear plug 2, line receptacle 5 and neutral receptacle 6 expose, the risk of contact can be produced, thus the width of the diameter of line receptacle 5 and neutral receptacle 6 is defined as and is less than 3mm, effectively can prevent the finger of people from stretching into and contact with conductive reed 13 or conducting ring 7.And the length of live wire tongue 9 and zero line tongue 10 should be short as far as possible, be separated to ensure that front plug 1 can comparatively be changed places with rear plug 2.
As preferably, described line receptacle 5 is tapered, the taper of described live wire tongue 9 in most advanced and sophisticated fillet.Because front plug 1 is likely subject to certain moment of flexure with rear plug 2 when being separated, non-fully axially loaded is separated, and live wire tongue 9 and line receptacle 5 is designed to taper and is more conducive to preventing live wire tongue 9 to be subject to moment of flexure and locked.
A kind of safety electric plug provided by the invention, can be separated completely when being subject to External Force Acting, thus ensures the safety of product and power supply.And front plug 1 is not easy to get an electric shock, all electrical connection interfaces are all less than the finger of human body, ensure Electrical Safety.Meanwhile, structure is simple, connects easily, easy to use.
The above embodiment only have expressed one embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
