Abstract
Two point type Hall watertight travel switch, is characterized in that comprising shell, screw thread, hall sensor component, casting glue, lead-in wire, tail nut, fluid sealant, vulcanized rubber, cable; Shell is the hollow stud of one end sealing, hollow stud outer surface is shaped with screw thread, with casting glue embedding after hollow stud interior accommodation hall sensor component, be provided with the hollow position of tail nut cap at hollow stud, the junction of tail nut and hollow stud is provided with fluid sealant, in hollow stud, the lead-in wire of hall sensor component is electrically connected with cable, and cable is drawn from tail nut; Cable is provided with vulcanized rubber sealing sheath from the extraction of tail nut.The utility model real work is in abyssal environment, and its intensity, sealing and corrosion resistance require all higher, utilizes structure of the present utility model Hall element reliably can be installed and outgoing signal.
Description
One. technical field
The utility model relates to a kind of switch, especially closed type travel switch.
Two. background technology
Hall watertight travel switch is the device of the detection position utilizing Hall effect principle to make.Its outstanding feature is in abyssal environment, detect the location status of motion, and have precision high, power consumption is little, sound construction; volume is little, lightweight, and the life-span is long, easy for installation; response frequency is high, vibration resistance, is not afraid of dust, greasy dirt, steam, salt fog and seawater etc. and pollutes or corrosion.Its operation principle is arranged on motion by magnetic steel component, when motion is near watertight travel switch, the Hall integrated circuit of travel switch inside detects the change in magnetic field and is translated into voltage signal, this signal undertaken amplifying by the amplifier of Hall integrated circuit inside and Schmidt trigger and shaping again by phase inverter and the load of power expansion circuit drives of outside, thus achieve process mechanical displacement signal being converted to the signal of telecommunication.
But the poor performance of water-stop when prior art prepares watertight travel switch.
Three. utility model content
The utility model object is, proposes the two point type Hall watertight travel switch of a kind of good reliability, long service life, good seal performance.
The technical solution of the utility model is, two point type Hall watertight travel switch, comprises shell, screw thread, hall sensor component, casting glue, lead-in wire, tail nut, fluid sealant, vulcanized rubber, cable; Shell is that hollow stud, the hollow stud outer surface of one end sealing is shaped with in screw thread, hollow stud and holds after hall sensor component with casting glue embedding, be provided with tail nut 5 and cover hollow position at hollow stud, tail nut 5 is provided with fluid sealant 6 with the junction of hollow stud, in hollow stud, the lead-in wire 4 of hall sensor component is electrically connected with cable 8, and cable 8 is drawn from tail nut 5; Cable 8 is provided with vulcanized rubber 7 sealing sheath from tail nut 5 extraction.
The beneficial effects of the utility model: the utility model real work is in abyssal environment, and its intensity, sealing and corrosion resistance require all higher, utilizes structure of the present utility model Hall element reliably can be installed and outgoing signal.Case body material is aluminium bronze, corrosion-resistantly ensure that two point type Hall watertight travel switch external structure is injury-free under severe conditions.The length of its nose threads seal section and rear end and rubber adapter section increases thus promotes its sealing property, and overstriking lengthens vulcanized rubber sealing expansion sheath and improves sealing and warping resistance further.
Four, accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Five, detailed description of the invention
As shown in the figure, shell 1, screw thread 1-1, hall sensor component 2, casting glue 3, lead-in wire 4, tail nut 5, fluid sealant 6, vulcanized rubber 7, cable 8.
Shell have employed aluminium bronze, shell 1 surface is shaped with screw thread, make it have higher intensity and good sealing property, and there is the performance of installing and fixing, inner embedding adopts L-II type thermal conductive insulation glue to improve its bulk strength, and thread seal place have employed Oil-proof Silicone Sealant HZ-1213 and improves its voltage endurance capability.Overstriking lengthens vulcanized rubber and improves sealing and warping resistance further.
The hall sensor component 2 of two point type Hall watertight travel switch inside is installed two and is overlapped independently Hall switch circuit and outsidely adopt enhancement mode vulcanized rubber hermetically-sealed construction, has higher circuit reliability and seal durability.Hall sensor component signal exports and receives cable, and provides operating voltage by cable.
Two point type Hall watertight travel switch mainly detects in order to the position realizing motion under abyssal environment, and its basic parameter is:
Operating voltage: 8-30V DC
Load current: every road is not more than 200mA
Operating distance: trigger point >=5mm, cut off≤10mm
Working environment: work in the seawater for a long time, operating pressure is 3Mpa;
Environment temperature :-40 DEG C ~+85 DEG C;
Impact resisting vibrating (meeting GJB4-83).
Insulaion resistance: be greater than 50M Ω
The length of its nose threads seal section and rear end and rubber adapter section increases thus promotes its sealing property, and overstriking lengthens vulcanized rubber and improves sealing and warping resistance further.
