Abstract
The utility model relates to an electronic sensor, in particular to a position sensing output module. The module shell is internally in the hollow shape and provided with a Hall sensor, and the outside of the Hall sensor is coated with epoxy resin. The utility model has the advantages of simple structure, long service life and high measuring precision.
Description
Technical field
The utility model relates to a kind of electronic sensor, especially relates to a kind of position sensing output module.
Background technology
Most of still sensor of contact-type that uses in the present automobile, the price of contactless sensor is not preponderated, but it has environmental protection, durable, antidetonation, easy contact type sensor such as the installations advantage that can't be equal to, and will be trend of the times to the development of contactless sensing direction.In the contactless sensor, by feat of advantages such as high reliability, hall effect sensor wins application space widely at automotive field.
A kind of utility model patent is called the Hall-type CMPS Camshaft Position Sensor, its patent No. is: CN200420018704.3, anodontia cam is signal panels on this utility model employing excircle, the top is equipped with housing, the position of going to the bottom in it is equipped with Hall chip IC, Hall chip IC is embedded on the circuit board of control circuit, circuit board and permanent-magnet steel closely are abutted against, circuit board and permanent-magnet steel are assemblied in respectively on the CMPS Camshaft Position Sensor internal frame, the CMPS Camshaft Position Sensor internal frame is provided with lead A, COM, the B end is connected with circuit board respectively, and is simple in structure, reasonable in design, the measuring accuracy height, detect dependable performance.Produce but in less position transducer, circuit and magnetic field are intensive, and electric leakage is arranged unavoidably, escape phenomenon such as electricity,,, also total system is produced harmful effect simultaneously will influencing greatly in serviceable life of position transducer in case these phenomenons occur.
Summary of the invention
The utility model mainly is short serviceable life at existing in prior technology, and the problem that measuring accuracy is not high provides a kind of long service life, the position sensing output module that measuring accuracy is high.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: described module housing inside is cavity-like, is provided with Hall element, and the Hall element outside scribbles epoxy resin.Epoxy resin plays insulating effect, does not have the negative effect of aspect, magnetic field again.
As preferably, described electric wire stretches into inside modules by protecting pipe, and is connected with Hall element.
As preferably, described electric wire is potted in by epoxy resin in inside modules with the part of Hall element, isolate mutually with the inside modules wall body.Epoxy resin is securing electric lines both, plays insulating effect again.
As preferably, the input end of described position sensing output module is provided with rotation axis, and auxilliary on the rotation axis have an O type circle.
As preferably, have cover plate on the described module housing, the cover plate plane is vertical with rotation axis.
As preferably, be with heat-shrinkable T bush on the described module housing, plug connector is installed in the heat-shrinkable T bush.
As preferably, described rotation axis is arranged with magnetic patch, alternating floor module housing wall between magnetic patch and Hall element.
Therefore, the utlity model has characteristics such as rational in infrastructure, long service life, measuring accuracy height.
