As shown in fig. 1, new-energy automobile high voltage cable, by center cable 1, inner restrictive coating 2, waterproof twining package tape 3, aluminium
Modeling composite shielding twining package tape 4 and 5 from-inner-to-outer of jacket layer successively coat；Wherein accurately description should for waterproof twining package tape 3
For outside inner restrictive coating 2.Plastic-aluminum combined shielding twining package tape 4 can play the role of the cable of reinforcing, while can also play screen
The effect covered.
As shown in connection with fig. 2, the center cable 1 includes the adjusting cavity 30 being axially arranged, and adjusts cavity 30 and is similar to one
A container, 30 both ends of adjusting cavity are respectively equipped with one group of conductor cable 100；100 quantity of conductor cable described in one group is 2,
Make it possible to realize that circuit controls in charging by single line cable；The conductor cable 100 adjusts cavity 30 and the interior shield
Filled layer is filled between jacket layer 2；Filled layer is generally gasket for packing, two groups of conductor cables 100 be respectively used to connection charging pile and
Vehicle power supply.
It is equipped with the first link block 10 and the second link block 20 in the adjusting cavity 30, and is connected with spring between the two
300；Spring 300 makes the first link block 10 and the second link block 20 have the trend being located remotely from each other.When the spring 300 does not occur
When deformation, first connecting hole 11 is not electrically connected with first connector 21, and second connecting hole 12 is not with described
The electrical connection of two connectors 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 with it is described
Adjust the electrical connection of conductor cable 100, first connector 21 and the second connector 22 and institute described in one group of 30 left side of cavity
It states and adjusts the electrical connection of conductor cable 100 described in one group of 30 right side of cavity；First link block 10 and the second link block 20
Outer diameter matches with the internal diameter for adjusting cavity 30.
First connecting hole 11 and first connector 21 matching setting；Second connecting hole 12 and described second
The matching setting of connection frame 22.

After the power supply of cutting charging pile, 10 left end of the first link block does not have electric current to flow into, 20 right side of the second link block
The voltage that car power supply voltage is less than former charging pile also can divide to fall many electricity simultaneously as power supply is connected with other electrical equipments
Pressure, reduces the voltage of the charging cable, so that the electric current passed through in electromagnetic coil 14 can also reduce, thus electromagnetism
Coil 14 becomes smaller to 24 gravitation of metal block, and gravitation is less than 300 elastic force of spring, and the first link block 10 and the second link block 20 are mutually remote
From, the electrical connection cutting of the component in the two, thus make whole electric discontinuity of cable, the conductor cable in 10 left side of the first link block
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 logical
Lu Hou, electromagnetic coil and resistance can persistently get 40V voltage；When taking out charging plug, automobile power source is connected with other electricity consumptions
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 electromagnetism
The gravitation of coil can also reduce therewith, and when gravitation is less than 300 elastic force of spring, the first link block 10 is transported far from the second link block 20
Dynamic, 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.
In conjunction with Fig. 3,4,10 right end of the first link block is equipped with the first isolation cover 13, and 20 left end of the second link block is set
There is the second isolation cover 23；First isolation cover 13 and 23 position of the second isolation cover are oppositely arranged, and the face that the two is opposite
It is equipped with opening；The electromagnetism connector 130 of first isolation cover, 13 right end is convex in 10 right side of the first link block, described
Second isolation cover, 23 left end is equipped with and the matched electromagnetism connecting hole 230 of the electromagnetism connector 130；First isolation cover, 13 He
Second isolation cover 23 be metal material；It and is cup configuration.
In conjunction with shown in Fig. 5,6, after the first link block 10 and the second link block 20 contact, the first isolation cover 13 and second every
It is connected from cover 23 by electromagnetism connector 130 and electromagnetism connecting hole 230, the first isolation cover 13 and the second isolation cover after the two connection
23 form a cylindrical shape, electromagnetic coil 14 and metal block 24 are shrouded in inside, so that electromagnetic coil be isolated to a certain extent
The influence of 14 pairs of electric currents.
