Abstract
The utility model discloses a crank shaft sensor having a direction identification function. The crank shaft sensor comprises a housing and a plug, wherein a support is disposed in the housing; a Hall chip having a direction identification function and a contact pin are fixed to the support; a pin foot of the contact pin and a pin of the Hall chip are mutually welded, an insertion end of the contact pin extends outside the housing and is connected with the plug; and the plug is molded with the housing into one through injection moulding. The chip adopted in the crank shaft sensor is the Hall chip having the direction identification function, and at the same time, the pin of the chip and the pin foot of the contact pin are directly welded together, and thus output precision of signals is substantially improved, the sensor is enabled to accurately identify an operation direction of the crank shaft at the first moment and to provide accurate output signals.
Description
Technical field
The utility model relates to the engine sensor technical field, more particularly, relates in particular to a kind of crankshaft sensor with direction recognition function.
Background technology
Crankshaft sensor is one of topmost sensor in electronic engine management system, and the signal that it provides time of ignition (ignition advance angle) and confirms crank position is for detection of piston top dead center, crank angle and engine speed.The crankshaft sensor of conventional design is to come output signal by reading the number of teeth, often can not judge the sense of rotation of bent axle, when engine kill, conventional crankshaft sensor can only just can provide signal after bent axle reverses 3～6 circles, and this brings certain danger to driving.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of crankshaft sensor with direction recognition function is provided, and it can identify the rotation direction of bent axle the very first time, and output signal accurately is provided.
For achieving the above object, crankshaft sensor with direction recognition function provided by the utility model, comprise housing and plug, be provided with support in described housing, be fixed with Hall chip and contact pin with direction recognition function on support, the stitch of contact pin and the pin of Hall chip are welded to each other, and the inserted terminal of contact pin stretches out outside housing and plug joins, and described plug is shaped to one by injection molding and housing.
The chip that the utility model adopts is the Hall chip with direction recognition function, simultaneously the pin of chip and the stitch of contact pin are directly welded together, improved widely the output accuracy of signal, make sensor can identify exactly in the very first time rotation direction of bent axle, and output signal accurately is provided.
