Specific embodiment
Invention is further explained with reference to the accompanying drawing:
In Fig. 2, new-energy automobile cable security component, by center cable, inner restrictive coating, waterproof twining package tape, plastic-aluminum
Composite shielding twining package tape and jacket layer from-inner-to-outer successively coat；Wherein waterproof twining package tape accurately describe should for around
Packet is outside inner restrictive coating.Plastic-aluminum combined shielding twining package tape can play the role of the cable of reinforcing, while can also play the work of shielding
With.
The center cable includes the adjusting cavity 30 being axially arranged, and adjusts cavity 30 and is similar to a container, the tune
Section 30 both ends of cavity are respectively equipped with one group of conductor cable 100；100 quantity of conductor cable described in one group is 2, makes it possible to pass through
Single line cable realizes that circuit controls in charging；The conductor cable 100 is adjusted and is filled out between cavity 30 and the inner restrictive coating
Filled with filled layer；Filled layer is generally gasket for packing, and two groups of conductor cables 100 are respectively used to connection charging pile and vehicle power supply.
In conjunction with shown in Fig. 1, be equipped with the first link block 10 and the second link block 20 in the adjusting cavity 30, and the two it
Between be connected with spring 300；Spring 300 makes the first link block 10 and the second link block 20 have the trend being located remotely from each other.Work as institute
When stating spring 300 deformation occurs, first connecting hole 11 is not electrically connected with first connector 21, and described second connects
Hole 12 is connect not to be electrically connected with second connector 22.
Conductor cable 100 described in two groups is fixedly connected on 30 both ends of adjusting cavity.Outside the every conductor cable 100
Layer is equipped with insulating layer.
First link block, 10 right side is equipped with the first connecting hole 11 and the second connecting hole 12, second link block 20
Left side is equipped with the first connector 21 and the second connector 22；First connecting hole 11 and second connecting hole 12 and institute
State and adjust conductor cable 100 described in one group of the left side of cavity 30 and be electrically connected, first connector 21 and the second connector 22 with
Conductor cable 100 described in one group for adjusting 30 right side of cavity is electrically connected；First link block 10 and the second link block 20
Outer diameter with it is described adjust cavity 30 internal diameter match.
First connecting hole 11 and first connector 21 matching setting；Second connecting hole 12 and described second
The matching setting of connection frame 22.
Electromagnetic coil 14 is axially arranged in first isolation cover 13,14 liang of binding posts of the electromagnetic coil are electrically connected
First connecting hole 11 and second connecting hole 12；Metal block 24 is equipped in second isolation cover 23.Metal block 24 has
It is magnetic, gravitation can be generated with electromagnetic coil 14, metal block 24 can be attracted by magnetic pole, which can be iron.
After the conductor cable 100 in 10 left side of the first link block connects charging pile, electromagnetic coil 14 has electric current by generating
Magnetic field is in series with resistance between the electromagnetic coil 14 and first connecting hole 11 or the second connecting hole 12.
In conjunction with Fig. 7, short circuit not will form due to being equipped with resistance；After the power on circuitry of left side, after electromagnetic coil 14 has magnetism,
It is attractive to metal block 24, and the two is close to each other, further, the first link block 10 and the second link block 20 also phase
Mutually close, spring 300 is extruded, and the first connecting hole 11 and 21 grafting of the first connector form electrical connection, 12 He of the second connecting hole

Car power supply voltage is less than the voltage of former charging pile, simultaneously as power supply is connected with other electrical equipments, also can divide to fall very much
Voltage reduces the voltage of the charging cable, so that the electric current passed through in electromagnetic coil 14 can also reduce, thus
Electromagnetic coil 14 becomes smaller to 24 gravitation of metal block, and gravitation is less than 300 elastic force of spring, the first link block 10 and the second link block 20
It is located remotely from each other, the electrical connection cutting of the component in the two, thus make whole electric discontinuity of cable, 10 left side of the first link block
Conductor cable 100 will not cause danger when being short-circuited.
It should be noted that the size setting of resistance needs to be set according to automobile virtual voltage, it is a kind of well-known technique.Than
Such as, charging voltage 220V, the moment that is powered can be understood as electromagnetic coil and resistance gets 220V voltage, when entire cable becomes
After access, electromagnetic coil and resistance can persistently get 40V voltage；When taking out charging plug, automobile power source is connected with other use
Electric equipment, then power supply gives the charging circuit and only has 20V, in electromagnetic coil 14 by electric current it is opposite before reduce half, then it is electric
The gravitation of magnetic coil can also reduce therewith, and when gravitation is less than 300 elastic force of spring, the first link block 10 is far from the second link block 20
Movement, to cut off circuit, then the circuit no current in 10 left side of the first link block passes through, and will not voluntarily connect into access.
The content in conjunction with shown in Fig. 5,6,10 right end of the first link block are equipped with the first isolation cover 13, second link block
20 left ends are equipped with the second isolation cover 23；First isolation cover 13 and 23 position of the second isolation cover are oppositely arranged, and the two
Opposite face is equipped with opening；The electromagnetism connector 130 of first isolation cover, 13 right end is convex right in first link block 10
End face, 23 left end of the second isolation cover are equipped with and the matched electromagnetism connecting hole 230 of the electromagnetism connector 130；Described first
Isolation cover 13 and second isolation cover 23 be metal material；It and is that cup configuration only has one end equipped with opening.
In conjunction with Fig. 3,4, after the first link block 10 and the contact of the second link block 20, the first isolation cover 13 and the second isolation cover
23 are connected by electromagnetism connector 130 and electromagnetism connecting hole 230, the first isolation cover 13 and the second isolation cover 23 after the two connection
A cylindrical shape is formed, electromagnetic coil 14 and metal block 24 are shrouded in inside, so that electromagnetic coil 14 be isolated to a certain extent
Influence to electric current.
