Description
Technical field
The utility model patent relates to a kind of switch, relates in particular to a kind of contactless vehicle speed sensor, is used for automobile.
Background technology
Present sensor of the prior art, the electronic devices and components in traditional vehicle speed mileage sensor and other parts all are installed in enclosure interior, the easy phase mutual friction of each parts and damaging; And poor radiation receives water, wet goods erosion easily, and traditional housing is an aluminium shell simultaneously; Cost of manufacture is high, and moulding is difficult, in the traditional product through closing with the magnet steel deallocation; Be easy to cause verticality bad, directly cause stuck and the electronic devices and components of grinding away.
Traditional vehicle speed mileage sensor provides signal through electronic devices and components and Hall element; In case make moist or problem on the welding technology occurring will cause mileometer to show problems such as inaccurate; The failure rate of product is very high; And coil all is to be wrapped in magnet steel, make the instability of face transducing signal easily, and serviceable life is not high.Though electromagnetic sensor can solve the mechanical wear and the difficult problem of installing and debugging that are prone to cause transducing part that existing touch sensor exists; But its structure relative complex; And magnetic signal is unstable, causes a deviation easily, and hazard rate is high.
Summary of the invention
The utility model mainly is to solve the deficiency that exists in the prior art, provides a kind of simple in structure, and can guarantee the contactless vehicle speed sensor of mission life.
The above-mentioned technical matters of the utility model mainly is able to solve through following technical proposals:
A kind of contactless vehicle speed sensor comprises housing, and the bottom of described housing is provided with plug-in unit; The head of described housing is provided with spiro connecting piece; Be provided with wiring board in the described housing, be provided with coil in the described spiro connecting piece, be provided with magnet steel in the described coil; One end of described wiring board is connected with coil, and the other end of described wiring board is connected with plug-in unit.
As preferably, described plug-in unit seals through O-ring seal with housing mutually, and the top of described housing is provided with pad.
The utility model provides contactless vehicle speed sensor, and is simple in structure, and usability is good, increases the service life.
