Abstract
The utility model relates to a speedy magnetic switch. One end of a reed is fixed, the other end is provided with a contact magnetic steel, an upper and a lower contact boxes are respectively arranged at both sides of the contact magnetic steel, an upper and a lower auxiliary magnetic steels which can slide are respectively arranged in the upper and the lower contact boxes, and an external magnetic steel is fixed on a signal sending device. The utility model has the advantages of simple structure, small size, low possibility of damage of the switch, no need of maintenance, long service life, and good vibration resistance. The signal emission is determined by the moving direction of the external magnetic steel, and has no relationship with the strength of applied force. The utility model can be carry 500 volt-ampere load.
Description
The utility model relates to a kind of electric signal switch, relates in particular to a kind of and the switch contactless memory travel switch relevant with the stroke of mechanism displacement of posting a letter.
Present widely used travel switch great majority will have the transmission mechanism of mechanical force, the transmission mechanism displacement signal of then can not sending out not in place, and displacement is excessive can to damage transferring elements again.For example near switch, its transmission mechanism and switch will be done head-on motion.Between the transmission mechanism parts relative motion is arranged, the time one, long can the generation worn and torn and stuck phenomenon, needed often to safeguard or adjust.With the travel switch of tongue tube work, because tongue tube two contact distances and area all can not be excessive, generally can not be with the above loads of tens of volt-ampere.With the travel switch that wet reed pipe is done, not only wet reed pipe is equipped with strict demand to the installation position, and its vibration resistance is also relatively poor, very easily damages.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provides a kind of simple in structure, but bringing onto load is big, Maintenance free, long service life, the contactless memory travel switch of the quick-action of good anti-vibration.
The purpose of this utility model can reach by following measure:
A kind of Speedy magnetic switch, comprise reed, auxiliary magnet steel and be fixed in outer steel on the signalling device parts, its special character is: described reed one end is fixed, the other end is provided with the contact magnet steel, upper and lower contact box is divided into magnet steel both sides, contact, be respectively equipped with in upper contact box and the following contact box can in box, slide on auxiliary magnet steel and time auxiliary magnet steel.
The tip side that upper and lower auxiliary magnet steel of the present utility model and contact magnet steel constitute is different pole mutually.
The accompanying drawing drawing is described as follows:
Fig. 1-3 is a structural representation of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing:
Referring to Fig. 1, one end of the utility model reed 1 is fixed, the other end is fixed with contact magnet steel 5, and upper contact box 2 and following contact box 3 are individually fixed in the both sides of contact magnet steel 5, be respectively equipped with in upper contact box 2 and the following contact box 3 can horizontally slip within it go up auxiliary magnet steel 4 and following auxiliary magnet steel 6.Reed 1 and upper and lower contact box 2,3 constitute a normally-open normally-close contact respectively, and the magnetic pole of upper and lower auxiliary magnet steel 4,6 and contact magnet steel 5 is arranged and should be guaranteed that tip side is different pole mutually.Outer steel 7 is fixed on the equipment unit, and its pole polarity is provided with identical with contact magnet steel 5.The setting of present embodiment magnetic pole is: upward auxiliary magnet steel 4 left ends are the N utmost point, and right-hand member is the S utmost point; Auxiliary magnet steel 6 left ends are the S utmost point down, and right-hand member is the N utmost point; Contact magnet steel 5 and outer steel 7 all are that the upper end is the N utmost point, and the lower end is the S utmost point.When outer steel 7 moves up to upper contact box 2 at same horizontal plane, it is identical with outer steel 7 bottom pole polarity to go up auxiliary magnet steel 4 right-hand members, external force will go up the left end that auxiliary magnet steel 4 is pushed into upper contact box 2, and contact magnet steel 5 is pushed in the process that outer steel 7 moves upward and auxiliary magnet steel 6 adhesives down.Referring to Fig. 2, outer steel 7 from up to down moves, the N utmost point of outer steel 7 upper ends is inhaled mutually with the S utmost point of last auxiliary magnet steel 4 right-hand members, go up the right-hand member that auxiliary magnet steel 4 is drawn to upper contact box 2, contact magnet steel 5 is attracted and moves upward, outer steel 7 continues to move to center line OO ', is a dead band when coincideing with the center line of contact magnet steel 5.When outer steel 7 continues to move downward, after crossing center line OO ', make a concerted effort upwards in the magnetic field that contact magnet steel 5 is subjected to, contact magnet steel 5 is pushed to upper contact box 2 rapidly, with last auxiliary magnet steel 4 adhesives, see Fig. 3, at this moment, outer steel 7 moves to down contact box 3, when same horizontal plane, because outer steel 7 upper ends are identical with following auxiliary magnet steel 6 right-hand member pole polarity, following auxiliary magnet steel 6 is pushed into down contact box 3 left ends by repulsion.
Upper and lower contact box of the present utility model can adopt silver-plated or gilding; Auxiliary magnet steel is good with rare earth magnetic steel, and this can guarantee stability, and makes volume-diminished.
The utility model compared with prior art has following advantage:
1, post a letter to be decided by whether outer steel moving direction and shift position cross the reed center line, irrelevant with application of force size, the position of therefore posting a letter is accurate, and repeatability is good.
2, the closing of contact or disconnection, only relevant with the outer steel direction of motion, the contact contact is reliable, and switch is not fragile, and long service life does not need to safeguard.
3, good anti-vibration can work in various relatively poor environment.
4, simple in structure, volume is little, and cost is low.
5, can be with 500 volt-amperes load.
Claims (2)
