L ', N ' and E ' connect vehicle plug 4, and vehicle socket 4 and cable through the control protection electric circuit 3.1 on cable in control protective unit 3
Both upper control protective units 3 are fixed on same housing.
Main improve is to be connected thereto between terminal L ', N ' and E ' in 2 end 3.2 of cable and be inserted into control protection electric circuit such as
Under:
--- 2 relays 1K and 2K in parallel are connected across 2 end 3.2 of cable after several protections of series connection and control contact
L, the pole N;
--- the pole L, N of 2 end 3.2 of Zenith tracking relay SU "Jumper" cable;
--- overcurrent detects relay SI and relay 1K, 2K each moving together contact series connection 2 end 3.2 of "Jumper" cable
The pole L is connected thereto terminal L ';
--- the pole N of another each moving together contact series connection 2 end 3.2 of "Jumper" cable relay 1K, 2K is connected thereto terminal N ';
--- above-mentioned relay 1K, 2K it is concatenated protection and control contact be overcurrent detect relay SI dynamic circuit breaker touching
Point, Zenith tracking relay SU break contact, be parallel with the moving together contact of relay 1K for self-locking start button QA.
The control protection electric circuit course of work is as follows:
--- it is electric for being obtained after the insertion power supply base of plug 1;
--- start button QA is pressed, relay 1K, 2K obtain electric, electromagnetic system movement, and closure moving together contact makes cable 2
L, N of end 3.2 are extremely respectively connected with the sub- L ' of corresponding output connector, N ', come from power supply base to the input of control protection electric circuit 3.1
Power supply, through control protection electric circuit 3.1 to 4 output voltage of vehicle plug;
--- after plug 1 pulls away power supply base, the voltage between bolt disappears therewith, relay 1K, 2K power loss, electromagnetic system
It resetting, the moving together contact of reset disconnects the pole L, N connection with corresponding output connector sub- L ', N ' respectively of 2 end 3.2 of cable,
Even if human body touches pull away socket after hanging bolt, will not be dangerous by being fed back from connection terminal L ', N ' to the pole bolt L, N
The electric shock of voltage;
--- so that overcurrent detection relay SI movement or supply voltage was made electricity greater than 250V when charging current is greater than 16A
Detection relay SU movement is pressed, their break contact powers off relay 1K, 2K, resets its electromagnetic system, and reset is moved
Conjunction contact disconnects the pole L, N connection with corresponding output connector sub- L ', N ' respectively of 2 end 3.2 of cable, stops charging, at this time
Even if human body touches pull away socket after hanging bolt, will not be dangerous by being fed back from connection terminal L ', N ' to the pole bolt L, N
The electric shock of voltage.
The embodiment of the present invention 2 is for plug circuit theory as shown in Figure 1, the circuit is met in prior art one kind
For improving on the basis of plug, continue to use structure is mainly GB1002 and GB2099.1:
--- bolt L, N and E for fixing for the original shell of plug and its mating surface and its outer conductor accordingly exported connect
Connecting terminal L ', N ' and E '.
Main improve be, is inserted between outer conductor connection terminal L ', N ' and the E ' in bolt L, N and E and its accordingly exported
Control protection electric circuit is as follows:
A) single-chip microprocessor MCU is set, it is whole through resistance 4R decompression, diode D1 from the pole bolt L with bolt N extremely common ground VSS
Stream, capacitor C filtering and voltage-stabiliser tube D2 pressure stabilizing, power to the power end VDD of single-chip microprocessor MCU;
B) the I/O port I1 input of single-chip microprocessor MCU detects signal by the supply voltage of resistance 1R and 2R partial pressure sampling;
C) action signal of the I/O port I2 input start button QA of single-chip microprocessor MCU;
D) the I/O port I3 of single-chip microprocessor MCU inputs the current detection signal sampled by resistance 3R;
E) the I/O port O1 output control transistor BG of single-chip microprocessor MCU drives relay 1K, 2K;
F) each moving together contact of relay 1K, 2K, which is in series connected across, patches the pole pin L and its outer conductor connection terminal L '
G) the another each moving together contact of relay 1K, 2K, which is in series connected across, patches the pole pin N (through current sense resistor 3R) and it leads outside
Line connection terminal N ';
H) single-chip microprocessor MCU plug-in implements the following course of work:

K1, K2 movement, are closed moving together contact, connect the pole L, N of bolt with corresponding output outer conductor connection terminal L ', N ' respectively, defeated
The power supply of electrical socket is confessed out.
--- after plug 1 pulls away power supply base, the voltage between bolt disappears therewith, loses the single-chip microprocessor MCU control of power supply
Relay 1K, 2K reset, they reset moving together contact disconnect bolt the pole L, N connect respectively with the outer conductor accordingly exported
The connection of terminal L ', N ' will not be by the outer conductors accordingly exported certainly even if human body touches bolt hanging after pulling away socket
Connection terminal L ', N ' feed back the electric shock of dangerous voltage to the pole bolt L, N;
--- the signal of I/O port I1, I3 input of single-chip microprocessor MCU shows that charging current is greater than 16A or supply voltage is greater than
When 250V, the I/O port O1 output signal of single-chip microprocessor MCU ends transistor BG, and relay 1K, the 2K controlled resets, reset
Moving together contact disconnects the pole L, N connection with the outer conductor connection terminal L ', N ' that accordingly export respectively of bolt, stops charging, this
Even if when human body touch pull away socket after hanging bolt, will not be by from outer conductor connection terminal L ', the N ' accordingly exported
The electric shock of dangerous voltage is fed back to the pole bolt L, N.
Because using single-chip microcontroller, the volume of the control protection electric circuit is greatly reduced compared to the 1st embodiment, can be packed into lesser insert
In casing, be conducive to the general various power devices of connection.
2 embodiment can have following improvement:
If --- former control protection electric circuit 3.1 has had overcurrent or overvoltage protection function in control protective unit 3 on cable
Can, then the overcurrent in above-described embodiment or excess voltage protection can be cancelled;
--- start button can be cancelled (as being shorted), and relay K1, K2 movement are after being inserted into power supply base for plug
Start immediately;
--- increase leakage protection circuit, as embodiment 1 can not take out stitches for plug 1 can be selected standardized product electric leakage
Protect plug, or in control protection electric circuit referring to traditional electric-leakage detection circuit detection leakage current and share relay 1K,
2K control: leakage current resets relay 1K, 2K when being more than specified value.
