Effect；It is also provided with wire casing and jack on second insulation board, is equipped with phosphor-bronze wire in the wire casing, the phosphor-bronze wire is used for
It is contacted with sheet metal, sheet metal is pierced by after contacting with phosphor-bronze wire by jack, and (CN108134230A) is utilized compared with prior art
Spring leaf contact, the arrangement of phosphor-bronze wire is more flexible and is not take up longitudinal space, and the space having more is used to arrange permanent magnet, so that
Magnetic field can preferably act on electronics, reach more preferably arc quenching effect.
Preferably, the phosphor-bronze wire has U-shaped elbow, short side and long side, forms gap just between the short side and long side
It is passed through in sheet metal, the U-shaped elbow is for being fixed on the second insulation board.
Preferably, the magnetic pole of the permanent magnet is horizontal direction arrangement, and the magnetic line of force and charged particle that permanent magnet is formed are transported
Dynamic direction is vertical, and therefore, magnetic pole is that horizontal direction arranges that the magnetic field effect to be formed is best.
Preferably, the phosphor-bronze wire and permanent magnet are arranged in parallel, and spring leaf is used in the prior art (CN108134230A)
Permanent magnet can not be then arranged in parallel, therefore the magnetic field arc quenching effect of generation in the prior art is poor.
Preferably, the axis direction of the phosphor-bronze wire and the pole orientation of permanent magnet are arranged vertically.
Preferably, thick screw hole is offered on first insulation board, is offered thin screw hole on second insulation board, is convenient for
The first insulation board and the second insulation board are fixed using screw.
The advantages of the utility model:
1. extinguishing arc socket device provided by the utility model can be reached with permanent magnet cooperation by phosphor-bronze wire and more preferably be gone out
Arc effect.
2. extinguishing arc socket device provided by the utility model can not allow permanent magnet to connect with electric arc by the first insulation board
Touching, but so that the magnetic line of force is acted on electric arc, and keep the magnetic line of force vertical with charging particle movement side, promote arc quenching effect.
