Abstract
The invention discloses a high-stability switch structure. The high-stability switch structure comprises a housing, first magnetic strips, a reed switch, a piston, a magnetic ring, a cylinder barrel and a second magnetic strip; the reed switch is arranged in the housing; the top of the inner wall of the housing is provided with the plurality of magnetic strips; the housing is arranged at the top of the cylinder barrel; one end of the housing is connected with a lead; the piston is located in the cylinder barrel; the magnetic ring wraps the piston; the second magnetic strip is arranged on the piston and is close to the reed switch; the magnetic property of the first magnetic strips is the same as that of the second magnetic strip. According to the high-stability switch structure, the unstable action is not produced by the external interference even in a magnetic retardation area to enable the movement range of a magnetic switch to be wide, a user can rapidly determine whether the switch works normally or not, and accordingly the use is flexible and stable.
Description
Technical field
The present invention relates to field of switches, be specifically related to high stability construction of switch.
Background technology
In the prior art, magnetic switch is used to detect cylinder piston position, namely detects the movement travel of piston, and magnetic switch is called point contact type magnetic switch or contactless triode type NPN and positive-negative-positive by the break-make that switch is carried out in the action of machinery electric shock.Magnetic switch has the advantages such as structure is simple, low price and is extensively used.There is magnetic hysteresis interval in the piston on existing magnetic switch, in magnetic hysteresis interval, switch motion easily occurs that action is unstable and be subject to the defects such as external interference, limits the moving range of magnetic switch, affects the normal use of switch in the back and forth movement of left and right.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, high stability construction of switch is provided, even if this switch is not also subject to external interference in magnetic hysteresis district and occurs the situation of action instability, makes the moving range of magnetic switch wider, can also judge whether switch normally works fast, use and stablize more flexibly.
For solving above-mentioned technical problem, the present invention is by the following technical solutions: high stability construction of switch, comprise shell, the first magnetic stripe, reed switch, piston, magnet ring, cylinder barrel and the second magnetic stripe, described reed switch is installed in the enclosure, at the inwall top of shell, polylith first magnetic stripe is also installed, shell is arranged on the top of cylinder barrel, also connects wire in one end of shell; Described piston is positioned at cylinder barrel, and piston also wraps up magnet ring; Described second magnetic stripe is arranged on also near reed switch on piston, and the first magnetic stripe and the second magnetic stripe Magnetic Phase are together.Piston arranges the second magnetic stripe, second magnetic stripe is near reed switch, magnetic hysteresis interval corresponding in inner walls arranges the first magnetic stripe, second magnetic stripe and the first magnetic stripe Magnetic Phase are together, when in the actuating range interval of piston in side-to-side movement, motion moves to magnetic hysteresis interval, make to be positioned at the second magnetic stripe on piston parallel to correspondence with the first magnetic stripe time, two magnetic stripe magnetic fields are identical, the magnetic influence that reed switch is strengthened and remain attracting state, avoid reed switch only higher in the centre position sensitivity of shell, and ectocine is subject in the magnetic hysteresis district on both sides, the situation of switch motion instability occurs, the moving range of reed switch is wider, use and stablize more flexibly.
Indicator light and protector are also installed in the inside of described shell.Indicator light person easy to use judges whether magnetic switch normally works fast, and protector, then for the protection of switch, makes its work more stable.
The inwall top of shell is provided with two piece of first magnetic stripe, and two piece of first magnetic stripe is symmetrical about reed switch.Piston is slided into be positioned at the magnetic hysteresis interval on reed switch both sides all can realize steady closure.
Described reed switch is arranged two pieces of parallel reeds.
Compared with prior art, the invention has the beneficial effects as follows:
1, the magnetic stripe that portion is identical with piston being arranged polarity is in the enclosure passed through, when piston moves left and right hysteresis area, the first magnetic stripe is identical with the magnetic direction on the second magnetic stripe, strengthens magnetic field, ensure that reed switch is not subject to ectocine in magnetic hysteresis district, stablizing of adhesive.
2, indicator light and protector are also installed in the inside of shell, and indicator light person easy to use judges whether magnetic switch normally works fast, and protector, then for the protection of switch, makes its work more stable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, Reference numeral is expressed as: 1, shell; 2, the first magnetic stripe; 3, indicator light; 4, reed switch; 5, piston; 6, magnet ring; 7, cylinder barrel; 8, wire; 9, the second magnetic stripe; 10, protector.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further elaborated, and embodiments of the invention are not limited thereto.
Embodiment 1:
As shown in Figure 1, the present invention includes shell 1, first magnetic stripe 2, reed switch 4, piston 5, magnet ring 6, cylinder barrel 7 and the second magnetic stripe 9, described reed switch 4 is arranged in shell 1, at the inwall top of shell 1, polylith first magnetic stripe 2 is also installed, shell 1 is arranged on the top of cylinder barrel 7, also connects wire 8 in one end of shell 1; Described piston 5 is positioned at cylinder barrel 7, and piston 5 also wraps up magnet ring 6; Described second magnetic stripe 9 to be arranged on piston 5 and near reed switch 4, first magnetic stripe 2 and the second magnetic stripe 9 Magnetic Phase with.
Taken shape in by reed switch in synthetic resin block, the cylinder piston with magnet ring moves from left to right, and reed switch enters in magnetic field, and two reeds are magnetized and attract each other, the closing of contact, sends a signal of telecommunication; When piston movement is to rightmost, reed switch leaves magnetic field, and reed loss of excitation, contact is thrown off automatically.A-B interval is called the actuating range of magnetic switch.During piston counter motion left, actuating range is that C-D is interval.C-D is interval and A-B is interval intersects mutually, and the position of each point is from left to right followed successively by D, A, C, B, and the actuating range of magnetic switch is generally at 5-14mm.B-C interval and D-A interval are called that magnetic hysteresis is interval, and this interval is less than 2mm usually.Intermediate position is called maximum sensitivity position.Piston arranges the second magnetic stripe, second magnetic stripe is near reed switch, magnetic hysteresis interval corresponding in inner walls arranges the first magnetic stripe, second magnetic stripe and the first magnetic stripe Magnetic Phase are together, when in the actuating range interval of piston in side-to-side movement, motion moves to magnetic hysteresis interval, make to be positioned at the second magnetic stripe on piston parallel to correspondence with the first magnetic stripe time, two magnetic stripe magnetic fields are identical, the magnetic influence that reed switch is strengthened and remain attracting state, avoid reed switch only higher in the centre position sensitivity of shell, and ectocine is subject in the magnetic hysteresis district on both sides, the situation of switch motion instability occurs, the moving range of reed switch is wider, use and stablize more flexibly.
