Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment the present invention will be further explained, as shown in Fig. 1,2,4,5：The invention provides a kind of special socket and its plug for carrying arc-control device of direct current, including：
A kind of special socket for carrying arc-control device of direct current, it include jack housing 2, socket panel 12,
Socket conductors 5, arc extinguishing conductor 4, unilateral diode 13 and arc-suppression circuit 8, the positive and negative end of the arc-suppression circuit 8 are connected with the positive and negative electrodes in same polarity of arc extinguishing conductor 4 respectively, and socket conductors 5 are connected with power line both positive and negative polarity respectively.Unilateral diode is concatenated between positive source and socket conductors positive pole, prevents reverse polarity connection from damaging arc-suppression circuit.
A kind of special matched plug for carrying arc-control device socket of direct current, including plug body 1, plug conductors 3, unilateral diode 7, the plug conductors 3 include positive pole, negative pole and the end of earthing pole three；Just extremely elongated cylinder, negative pole are prolate cube to the plug conductors 3, and its positive pole connects unilateral diode 7, make plug powered because of perception and the inverse electromotive force of capacitive device in equipment after preventing reverse polarity connection damage equipment and extracting.
Plug has positive pole, just three conductors of negative pole and ground connection, extremely elongated cylinder, and negative pole is prolate cube, and diameter, width are equal, equal length, ground connection extremely elongated cylinder, slightly thin more slightly longer than positive pole.There are two groups of conductors of arc extinguishing and socket power in socket, shape distinguishes the shape of corresponding plug conductor, to be in close contact good conductive.The shape of socket panel jack also corresponding plug, will not wrong plug it is anti-inserted.
4 points of arc extinguishing conductor is two groups of positive and negative electrode, respectively the shape of the both positive and negative polarity of corresponding plug conductor 1, and is fixed on socket panel by bolt 11（12）Below.
5 points of socket conductors are positive and negative, three groups of earthing pole, and difference corresponding plug conductor is positive and negative, earthing pole shape, and is fixed on socket conductors insulating base 6 by bolt 10.
The positive pole of the plug conductors, arc extinguishing conductor and socket conductors is different from negative pole shape, and positive pole in the present embodiment selects prolate cube from elongated cylinder, negative pole, to show differentiation；Other shapes are also can select in addition to distinguish positive and negative two-stage, and the purpose of reversal connection is prevented to reach.
Arc quenching principle of the invention is as shown in Figure 1-2：
When a plug is to be inserted into the socket, plug conductors 3 are powered by unilateral diode 7 by inserting socket conductors 5, positive source after arc extinguishing conductor 4 to equipment, circuit turn-on, while being powered to arc-suppression circuit 8 by arc extinguishing conductor 4.
When plug extracts socket, plug conductors 3 continue to be contacted with arc extinguishing conductor 4 after departing from socket conductors 5, now have the potential equal with socket conductors 5 on arc extinguishing conductor 4, without the voltage difference for producing electric arc enough, will not produce electric arc.When plug conductors 3 continue to depart from arc extinguishing conductor 4, the distance for producing electric arc is lost between plug conductors 3 and socket conductors 5, and the energy storage very little of arc-suppression circuit 8 is also insufficient to allow between arc extinguishing conductor 4 and plug conductors 3 and produces electric arc.
Arc-suppression circuit of the invention is as shown in Figure 3：
When the circuit is on, positive pole A is charged by current-limiting resistance R and charging diode Z3 to electric capacity C, just lower negative in polarity, electric current is flowed back to by negative pole B, when a circuit is open, electric capacity C passes through fly-wheel diode Z2 repid discharges, A ends are for just, B ends are negative, are maintained equal with the potential of power supply, prevent voltage difference and possess discharging condition, prevent the generation of electric arc.
Content described in this specification embodiment is only to realize enumerating for pattern to inventive concept; protection scope of the present invention is not construed as being only limitted to the concrete form that embodiment is stated, protection scope of the present invention also and in those skilled in the art according to present inventive concept it is conceivable that equivalent technologies mean.
