Abstract
The utility model relates to an outer sleeve for a normally-open magnetic sensor. As at the opening end of a sleeve body, a magnetic switch is provided with a water-proof plug and is matched with a water-proof nut, the whole water-proof and humidity resistance properties of a product are improved greatly; and as a pair of symmetrical guide slots are arranged on the inner wall of the sleeve body, a circuit board can be clamped in the guide slot, so that the phenomena of collision and damage can be avoided in the using process, the service life of the product is prolonged, and the costs for maintenance and use are reduced. As the circuit board and a wire at one end of the circuit board are not welded and fixed with the outer sleeve, the daily maintenance and replace are facilitated.
Description
Technical field
The utility model relates to the technical field of magnet contactor, and specifically a kind of Elevator landing device, elevator magnet contactor of leveling device again that is used for relates in particular to the housing physical construction of often opening magnet contactor.
Background technology
The wide model of magnet contactor series products is applied to household electrical appliances number, mechanical control, automobile, industry control security protection, elevator or the like numerous areas, and it is with low cost, and is practical, and stable performance has obtained users' approval.
(photoelectric switch product precision can be controlled in ± 1mm, and conventional type of magnet contactor precision can only reach ± 4mm), field of application receives very big restriction but its actv. actuation range, the operation precision of magnet contactor and existing photoelectricity series products also have a certain distance.Such as, at elevator again in the flat bed field, because of being difficult to guarantee precision, and can't be applied.
So-called elevator flat bed again is meant elevator when the access door district, and the Elevator landing device can be given signal of elevator, and elevator is according to this signal; Begin braking; Because the inertia of elevator brake will cause elevator not to be parked in level position exactly, at this time; Need apparatus for controlling elevator that the position of elevator is adjusted, so that elevator is parked in position exactly.Let apparatus for controlling elevator make control command, must send the signal of flat bed to control system again, sending of this signal is exactly elevator leveling device role again.
Elevator leveling device again need be installed in the top of elevator cab; Working environment humidity is bigger; So moistureproof damp proof having relatively high expectations to the magnetic strength device; And existing magnetic strength device not only operation precision can't guarantee that its containment structure also can't satisfy the elevator installation needs of leveling device again, moistureproof moisture-proof characteristic is relatively poor.Existing magnetic strength device in-to-in circuit card, electric wire output adopt the mode of welding to be connected with magnetic strength device itself simultaneously; Because circuit card has only an end and housing relative fixed; In the use of magnetic strength device; Circuit card bumps in housing easily and damages, and has increased maintenance and use cost, and integrally welded this fixed form makes troubles also for the maintenance and the replacement of daily magnetic strength device.
Summary of the invention
The purpose of the utility model is to provide a kind of improved Elevator landing magnet contactor of using, and it is relatively poor that it can overcome in the prior art the moistureproof moisture-proof characteristic of containment structure, maintenance and replacement inconvenience, the some shortcomings that use cost is higher.
To achieve these goals; The technical scheme of the utility model is: a kind of Elevator landing magnet contactor, and it mainly comprises union body and is located at union body in-to-in circuit card; It is characterized in that: the surface of union body is provided with outside thread; Outside thread is provided with waterproof nut and captive nut, and an end of union body is provided with the waterproof plug, and the waterproof nut sleeve is located at an end of union body and matches with the waterproof plug.
During use, the magnet contactor of the utility model is combined with the waterproof nut again owing to the open end at union body both had been provided with the waterproof plug; Make product single-piece waterproof, anti-soak properties promote greatly; Because the inwall of union body is provided with the guide groove of one group of symmetry, make circuit card can be fastened in the guide groove again, in use can not bump and damage; Prolonged the service life of product, the cost that has reduced maintenance and used.Because the electric wire of circuit card and circuit card one end is not to weld to fix with outer tube, for daily maintenance and replacement brought convenient.

Fig. 4 is the running condition reference diagram of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe.
The utility model mainly comprises union body 1; Be located at union body in-to-in circuit card; Its difference with the prior art is: the surface of union body is provided with outside thread 2; Outside thread is provided with waterproof nut 3 and captive nut 4, and an end of union body is provided with waterproof plug 5, and the waterproof nut sleeve is located at an end of union body and matches with the waterproof plug.The inwall of union body is provided with the guide groove 6 of one group of symmetry, and the degree of depth of guide groove is 75mm-95mm.Circuit card mentioned above is a prior art, has just repeated no more its topology layout and principle of work here.
The waterproof plug is " T " font, and the waterproof plug is provided with the electric conduit 9 that runs through the waterproof plug, and the waterproof nut is provided with the through hole that matches with electric conduit.Captive nut has 2, and two captive nuts are arranged on externally threaded interlude in opposite directions.One end of union body is a closed end; The other end is an open end, and the outside face that links to each other with open end is provided with outside thread, and externally threaded length accounts for 3/5-1/3 of union body length; Outside face between closed end and the outside thread is a smooth side, and a side of smooth side is provided with scale 7.The waterproof nut is arranged on the open end of union body.Union body adopts nylon material to process.
In force, the utility model is installed in the top of elevator cab, and magnetic stripe 8 sticks on the cage guide and is used with this product; The open end inside of union body is provided with the waterproof plug; The outside is combined with the waterproof nut again, makes the waterproof of product, anti-soak properties obtain duplicate protection, and the inwall of union body is provided with the guide groove of one group of symmetry; Circuit card can be fastened in the guide groove and the union body relative fixed; Make circuit card in use be not easy to bump and damage, prolonged the service life of product, the cost that has reduced maintenance and used.Because circuit-board card is located in the union body, the electric wire of circuit card one end is through electric conduit and external linkage on the waterproof plug, and it is convenient that above-mentioned connection mode is that daily maintenance and replacement have brought.
