Description
Technical field
The utility model relates to a kind of automobile sensor, what be specifically related to is a kind of automobile crane position transducer.
Background technology
Crankshaft position sensor is for detection of the automobile engine crankshaft angle position, be arranged on ignition distributor, whether can accurately detect each cylinder after engine operation works well, as certain cylinder crankshaft does not reach top dead center position, this sensor feeds back at once control module (ECU) and judges whether to travel or to stop.The crankshaft position sensor of prior art, have shell and upper cover usually, in shell, after the installation parts, will be covered with upper cover, and upper cover general using close-fitting mode and shell fixed engagement, also will apply glue in junction in advance.
Summary of the invention
In view of the problem that current known technology exists, the technical problems to be solved in the utility model is to provide a kind of crankshaft position sensor simple in structure, easy to assembly.
For solving the problems of the technologies described above, the utility model takes following technical scheme to complete:
Crankshaft position sensor, comprise shell and wiring board, it is characterized in that: wiring board is installed on Hall cannon born frame, Hall cannon born frame is inserted in shell from the open top of shell, the bottom of Hall cannon born frame is equipped with the Hall pipe, the top of Hall cannon born frame is provided with Plug pin patch bay, contact pin is installed in Plug pin patch bay, the Hall pipe is electrically connected to wiring board by wiring pin, the front of Hall pipe is near the shell bottom surface, the back side of Hall pipe is provided with magnet, and magnet is fixing in the circuit board, and wiring board is exported with contact pin and is electrically connected to by three binding posts.The open top of described shell is provided with blanching and closes the in-flanges of formation Hall cannon born frame and shell are fixed together.
The crankshaft position sensor of technique scheme, simple in structure, assemble very convenient, at first all parts are comprised to wiring board, Hall pipe and magnet etc. (except shell) all are installed on Hall cannon born frame, then Hall cannon born frame is inserted into to the endoporus of shell, finally by blanching close the cover top portion opening make open top form in-flanges just Hall cannon born frame be fixed together and complete assembling with shell, whole assembling process very simply.The principle of work of above-mentioned crankshaft position sensor is: when the signal wheel rotates, form the magnetic circuit of a variation between Hall pipe in signal wheel and sensor, magnet, when the double wedge of signal wheel over against or while leaving the sensitive surface of magnet, magnetic flux changes, so the Hall pipe by the magnetic flux change information that detects after the wiring board inner modulation, output signal to control module (ECU) and judge whether to travel or to stop, guarantee traffic safety.
The accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model.
Embodiment
Accompanying drawing has meaned the technical solution of the utility model and embodiment, below further describes by reference to the accompanying drawings each details and the principle of work thereof of embodiment again.
As shown in the figure, crankshaft position sensor of the present utility model, comprise shell 1 and wiring board 7, wiring board 7 is installed on Hall cannon born frame 4, Hall cannon born frame 4 is inserted in shell 1 from the open top of shell 1, the bottom of Hall cannon born frame 4 is equipped with Hall pipe 11, the top of Hall cannon born frame 4 is provided with Plug pin patch bay 3, the interior installation contact pin 2 of Plug pin patch bay 3, Hall pipe 11 is electrically connected to wiring board 7 by wiring pin 9, the front of Hall pipe 11 is near shell 1 bottom surface, the back side of Hall pipe 11 is provided with magnet 10, magnet 10 is fixed on wiring board 7, wiring board 7 is exported with contact pin 2 and is electrically connected to by three binding posts 6, the open top of described shell 1 is provided with the in-flanges 5 that blanching closes formation Hall cannon born frame 4 and shell 1 is fixed together, and the mounting hole 12 of sensor is located on shell 1, is provided with in mounting hole 12 copper sheathing 8 is installed.
The utility model is work like this: the utility model is installed on motor car engine, when the signal wheel rotates, form the magnetic circuit of a variation between Hall pipe in signal wheel and sensor, magnet, when the double wedge of signal wheel over against or while leaving the sensitive surface of magnet, magnetic flux changes, so the Hall pipe after the wiring board inner modulation, outputs signal to the magnetic flux change information that detects control module (ECU) and judges whether to travel or to stop, and guarantees traffic safety.
