Abstract
The utility model discloses a cam shaft sensor, which comprises a shell, a plug, a circuit board and a Hall generator, wherein the plug is clamped with the shell in a matching way; the circuit board is arranged in the shell; the Hall generator is connected with the circuit board; a plurality of plug sheets are assembled in the plug and are connected with the circuit board; and the Hall generator consists of a Hall element and magnetic steel. By adopting the structure, the cam shaft sensor provided by the utility model is a signal generator using the Hall effect, which is used for acquiring a position signal of a gas mixing cam shaft and inputting the position signal into an ECU (Electronic Control Unit), so that the cylinder compression top dead center can be recognized by the ECU, and furthermore, oil injection control, ignition moment control and detonation control are sequentially performed. Since a small number of parts are used by the cam shaft sensor provided by the utility model, the cam shaft sensor provided by the utility model has a simple structure and is convenient for a user to mount and use.
Description
Technical field
The utility model relates to a kind of camshaft-signal sensor.
Background technology
At present, along with global automobile industry improving constantly to emission standard, impelling car load ECU that the dense dilution of engine mixed gas body and the control accuracy of optimum igniting time are required will be more and more higher, camshaft-signal sensor then is one of most important sensor in the automotive electronic control system system, but existing camshaft-signal sensor structure is complicated, and installation and use are all extremely inconvenient.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of camshaft-signal sensor simple in structure, easy to install.
For achieving the above object, the utility model provides a kind of camshaft-signal sensor, comprise shell, plug, wiring board, Hall generator, described plug and shell card are joined, wiring board is located in the shell, Hall generator is connected with wiring board, is equipped with some inserted sheets in the described plug, and described inserted sheet is connected with wiring board.
The utility model can further be set to described Hall generator and be made of Hall element and magnet steel.
The beneficial effects of the utility model are: adopt said structure, camshaft-signal sensor provided by the utility model is a kind of signal generator that utilizes Hall effect, be used to gather the position signalling of distribution cam axle, and input ECU, so that ECU identification cylinder compression top center, thereby carry out order oil spout control, time of ignition control and detonation control.Because the used parts of camshaft-signal sensor provided by the utility model are less, therefore camshaft-signal sensor provided by the utility model is simple in structure, and is convenient to user installation and use.
Description of drawings
Fig. 1 is a structure cut-open view of the present utility model.
Embodiment
Provided a kind of camshaft-signal sensor as shown in Figure 1, comprise shell 1, plug 2, wiring board 3, Hall generator 4, described plug 2 is joined with shell 1 card, wiring board 3 is located in the shell 1, Hall generator 4 is connected with wiring board 3, be equipped with some inserted sheets 21 in the described plug 2, described inserted sheet 21 is connected with wiring board 3.Described Hall generator 4 is made of Hall element 41 and magnet steel 42.
Adopt said structure, camshaft-signal sensor provided by the utility model is a kind of signal generator that utilizes Hall effect, be used to gather the position signalling of distribution cam axle, and input ECU, so that ECU identification cylinder compression top center, thereby carry out order oil spout control, time of ignition control and detonation control.Because the used parts of camshaft-signal sensor provided by the utility model are less, therefore camshaft-signal sensor provided by the utility model is simple in structure, and is convenient to user installation and use.
