Description
Technical field
The utility model relates to Elevator landing switchgear field, and particularly a kind of Elevator landing is used bistable magnetic swich.
Background technology
Widely used leveling device is exactly the transducer that produces the Elevator landing signal in the Elevator landing field, and when elevator arrived each layer, transducer all will send the signal that arrives at a station.According to the difference of elevator structure and purposes, transducer uses different patterns usually.The normal at present transducer that adopts mainly contains magnetic inductor, bistable switch, optoelectronic switch, Hall switch etc.
Though the Switch product is compared its advantage with magnetic inductor; But use can't be brought into play real flat bed effect at all separately; And the Switch product needed just can be had an effect under the situation of energising; So just exist except that useful power consumption, diminish power consumption in addition, stop all kinds of perils in case have a power failure to have only by closing whole elevator.
It is slow that also there is response speed in mechanical switch in addition, limited service life, shortcoming such as reliability is low; And because the various defectives that itself exists are very easily damaged, therefore will reach desirable flat bed effect just need be used in combination other multiple switches, and therefore a function needs a plurality of switches to use simultaneously; So just make to reaching a function and just need the high cost of cost; And in a single day mechanical switch damages, just need to seek the source and make the rising of maintenance cost straight line again, and also extremely loaded down with trivial details at unloading process.
And if do not use mechanical switch to use magnetic induction switch, though magnetic induction switch is compared with mechanical switch and do not had response speed slow, limited service life; Shortcomings such as reliability is low; But the magnetic inductor leveling device only relies on the screening magnetic sheet that is installed on the well enclosure to interact, and the actual environment of installing is quite abominable, and magnetic induction switch receives the influence of dust, moisture easily in addition; Usually can send wrong signal, cause the consequence that to retrieve.
Tongue tube is a kind of special key of magnetosensitive, also claims dry-reed relay.It is usually by two or three reed contacts that soft magnetic material is made; Reed contact is encapsulated in the glass tube that is filled with inert gas (like nitrogen, helium etc.) or vacuum; The leaf end of parallel encapsulation is overlapping in the glass tube, and leaves certain interval or be in contact with one another often opening or normally-closed contact with the formation switch.
Since tongue tube compare with the common mechanical switch have simple in structure, volume is little, speed is high, the characteristics of long working life; And compare with electronic switch, it has characteristics such as anti-load shock ability is strong again, and functional reliability is very high.Therefore at present many magnetic switches bring into use tongue tube to use as relay in the switch.
Magnetic switch mainly uses bar permanent magnet to magnetize around the tongue tube reed that makes on the tongue tube near tongue tube or with the magnetic field that coil electricity forms with tongue tube at present; Because the particularity of Elevator landing magnetic field environment need the more weak permanent magnet of magnetic, and bar permanent magnet magnetic is stronger; And be difficult for magnetic is controlled; Therefore should not use at this, and magnetize around the tongue tube reed that makes on the tongue tube in the magnetic field of using coil electricity to form, though can this magnetic be controlled; But structure is too complicated again, seeing that the particularity of Elevator landing magnetic field environment does not need so complicated structure.
The utility model content
To above problem, the utility model is used bistable magnetic swich through a kind of Elevator landing of design, and this bistable magnetic swich utilizes the particularity of Elevator landing switch environment; The tongue tube that use is with circular magnet with relay in the switch, because dry reed-pipe structure is compact, weight is little, therefore can be installed in the extremely limited space as Elevator landing; Thereby it is safe and reliable to have improved switch greatly, has reduced noise and vibrations, for reaching this purpose; The utility model provides a kind of Elevator landing to use bistable magnetic swich, comprises bistable magnetic swich shell, lead and copper Binding post/stud, and an end has the inside and outside wiring inlet that connects in the said bistable magnetic swich shell; There is installing hole bistable magnetic swich shell upper end; Said bistable magnetic swich also comprises tongue tube and annular magnet, in the said bistable magnetic swich shell tongue tube mounting groove is arranged, and said copper Binding post/stud is arranged on the tongue tube mounting groove and is connected between the wiring inlet with inside and outside; Said copper Binding post/stud has two rows; Said every row's copper Binding post/stud has two copper Binding post/studs, and tongue tube and foreskin lead are arranged in the said tongue tube mounting groove, and tongue tube and foreskin lead are arranged side by side; The vitreum at said reed switch contact position is set with annular magnet outward; Said tongue tube tail end links to each other with first row's diplopore copper Binding post/stud through lead, and said foreskin lead one end links to each other with second row's diplopore copper Binding post/stud through the peeling lead, links to each other through pad between said tongue tube and the foreskin lead.
As the further improvement of the utility model, there is the part shock-absorption said tongue tube mounting groove tongue tube both sides, through the part shock-absorption is set tongue tube useful life can be provided.
As the further improvement of the utility model, said bistable magnetic swich shell upper end installing hole has 2-4, and this patent needs to be provided with according to the switch model installing hole of respective numbers.
The utility model bistable magnetic swich utilizes the particularity of Elevator landing switch environment, use be with circular magnet tongue tube as Elevator landing with relay in the switch, because dry reed-pipe structure compactness, weight are little; Therefore can be installed in the extremely limited space, thereby it is safe and reliable to have improved switch greatly, has reduced noise and vibrations; Make whole switch more steady when playing braking, installation connection is more easy, the operation of being more convenient for; This patent is provided with the inner body shock-absorption around tongue tube in addition; Thereby prolonged the useful life of whole tongue tube, in addition because this patent is according to Elevator landing switch environment particular design, so this patent also has response rapidly; Cost is low, the characteristics that economic performance is good.
