Embodiment
Below in conjunction with embodiment, the utility model is described in further detail:
Embodiment
As shown in Figure 1, magnetic quenching formula high-voltage electric connector of the present utility model comprises forming contact right the first terminal 1 and the second terminal 2, and this first terminal 1 and the second terminal 2 all are arranged in holder.Holder of the present utility model is made as pedestal, and this pedestal comprises pedestal 1 and pedestal 26, and 1 of described the first terminal is arranged in this pedestal 1, and the second terminal 2 is arranged in pedestal 26.For the ease of arc extinguishing, also be respectively equipped with magnet 3 and high magnetic permeability solid 4 in described pedestal.
As shown in Figure 1, described magnet 3 all is arranged in pedestal 26 with high magnetic permeability solid 4, and this magnet 3 and high magnetic permeability solid 4 lay respectively at the left and right sides of the second terminal 2.The N utmost point of the magnet 3 in the utility model or the S utmost point are over against high magnetic permeability solid 4.Described high magnetic permeability solid 4 is made by high-permeability material, high magnetic permeability solid 4 in the present embodiment is made by one or more in the pig iron, industrial silicon Steel material, silicon nickel alloy and polyaniline, the material of making high magnetic permeability solid 4 is not limited to above several, can also be other materials with high magnetic permeability.For the ease of magnet 3 and high magnetic permeability solid 4 are fixed on pedestal 26, magnet 3 of the present utility model is arranged on the sidewall of pedestal 26, as shown in Figure 1 by the mode of inlaying with high magnetic permeability solid 4.Magnet 3 of the present utility model can also be fixed on pedestal 26 by bonding or other connected mode with high magnetic permeability solid 4, so that magnet 3 keeps constant with the reinforced magnetic field that high magnetic permeability solid 4 produces.
Fig. 2 and Fig. 3 have provided the magnetic quenching principle schematic of the high-voltage electric connector that is provided with magnet 3 and high magnetic permeability solid 4, and in the present embodiment, the hypothesis the first terminal is positive terminal, and the second terminal is negative terminal; When the first terminal 1 and the second terminal 2 plugged together, when the first terminal 1 and 2 voltages of the second terminal and distance reached certain condition, the electronics on the second terminal 2 obtained enough large kinetic energy and breaks away from the second terminal 2 to the first terminal 1 emission, thus generation electric arc.after adding magnet 3 and high magnetic permeability solid 4, the zone of the first terminal 1 and the second terminal 2 generation electric arcs is passed in the magnetic field that the magnet 3 of strengthening through high magnetic permeability solid 4 produces, learn that by left hand rule moving charge in magnetic field is subjected to as shown in Figure 3 to the Lorentz force of right (or in the other direction) as can be known, when the Lorentz force of 3 pairs of the first terminals of magnet, 1 emission moving electron reaches certain value, the movement locus of electronics is offset out the space between the first terminal 1 and the second terminal 2, thereby the air between the first terminal 1 and the second terminal 2 can not be ionized fully, can make electric arc lose the ignition condition, the extension ignition, make the first terminal 1 and the second terminal 2 plug together the electric arc that does not produce electric arc or generation in process and have (even and have electric arc, due to the effect of Lorentz force, the electric arc of generation is also the state that is cooled at) in the utmost point short time, when the first terminal 1 separated with the second terminal 2, identical with above-mentioned action principle, due to the effect of Lorentz force, the electric arc that produces between the first terminal 1 and the second terminal 2 elongated rapidly, make the electric arc lighted fast cooling, extinguish, thereby avoided the first terminal 1 and the second terminal 2 by scaling loss, guaranteed the reliability of high-voltage electric connector, improved the useful life of high-voltage electric connector, (just the direction under configuration state is to the right in the drawings for the Lorentz force direction that provides in Fig. 2 to have avoided the generation of peril, but the Lorentz force direction is not limited to this, and is fixed according to actual conditions).
As shown in Figures 2 and 3, because magnet 3 and high magnetic permeability solid 4 can be done very littlely, distance between magnet 3, high magnetic permeability solid 4 and the second terminal 2 can be quite near, therefore can regard magnet 3 as constant (line of magnetic induction is perpendicular to magnet 3 surfaces) in the magnetic field that electric arc produces the zone generation; The electronics initial velocity is made as zero, obtains theoretical formula and is: theoretical magnetic flux density absolute value
And find in experiment, the absolute value of the actual magnetic induction P durection component of (with distance solid magnets surface being as the criterion farthest) position need to satisfy as shown in A line in Fig. 2 between the first terminal or the second terminal:
Wherein, d produces the operating distance of electric arc between the first terminal 1 and the second terminal 2; L is that the first terminal 1 or the second terminal 2(are with large being as the criterion of end face width) the end face width; Q is the electrically charged amount in electron institute; M is electron mass; U is the first terminal 1 when contacting with the second terminal 2, is added in the voltage at the first terminal 1 and the second terminal 2 two ends.Passable by above-mentioned analysis, the absolute value of the actual magnetic induction P durection component of the actual magnetic induction position of (with distance solid magnets surface being as the criterion farthest) need to satisfy as shown in A line in Fig. 2 between the first terminal 1 and the second terminal 2:
Just can play good arc extinguishing effect, can better block, postpone the ignition of electric arc when also namely plugging together, during separation can better to the electric arc that produced fast cooling, extinguish.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
