Description
Technical field
This utility model relates to a kind of sensor technology, is specifically related to a kind of vehicle cam shaft position sensor.
Background technology
In automobile electric control system, CMPS Camshaft Position Sensor is for gathering the position signalling of distribution cam axle, and inputs ECU, in order to ECU identifies cylinder compression top dead centre, controls thus carrying out sequential fuel injection control, time of ignition control and detonation.
The CMPS Camshaft Position Sensor of prior art, owing to shell comprises installation orifice, so mould structure is complicated；Skeleton comprises terminal, operation inconvenience during injection moulding, and production efficiency is low, and terminal also wants mold simultaneously, adds manufacturing cost.Generally speaking this design structure is complicated, and technical process is more, and the production cycle is long, uses mould more, and production cost is higher.
Utility model content
Goal of the invention: the purpose of this utility model is in that to solve the deficiencies in the prior art, it is provided that a kind of vehicle cam shaft position sensor, this utility model simple in construction, technical process simply easily realize, and production efficiency is high, cheap for manufacturing cost.
Technical scheme: a kind of vehicle cam shaft position sensor of the present utility model, including sensor body and bundle assembly, sensor body includes sensing head and injection moulding body, described sensing head includes frame body, circuit board, Hall chip and magnet steel, magnet steel snaps in frame body, and Hall chip adopts soldering by chip stitch with circuit board；Described injection moulding body injection moulding, outside sensing head, injection moulding body is provided with the junction of frame body lining and sealing ring；Described bundle assembly includes cable wire harness, cable harness protection sleeve and adapter, and one end of cable wire harness is connected to adapter, the other end and circuit board wiring hole soldering, and cable harness protection sleeve is placed on outside cable wire harness.
Further, described frame body is provided with the mounting groove corresponding with Hall chip and circuit board.
Further, described sealing ring is O RunddichtringO and is installed in the seal groove on injection moulding body.
In order to improve insulating properties, corrosion resistance and thermostability, described sensing head pours into epoxide-resin glue and has formed epoxy glue layer.
Beneficial effect: compared with prior art, this utility model has the advantage that
(1) snapping in frame body by magnet steel, pouring into of epoxide-resin glue makes sensing head and shell and is integrated, the reliability of the product of raising, insulating properties, corrosion resistance and thermostability；
(2) injection moulding of injection moulding body is outside also simultaneously together with installing lining and being injection-moulded in sensing head, eliminates the installation of additional location-plate, decreases cost, improves production efficiency；
(3) bundle assembly directly with circuit board wiring hole employing soldering, eliminate terminal transition, reduce by a welding sequence, easily operate, decrease terminal die cost, simplify skeleton die structure, reduce die cost, improve production efficiency.
In sum, this utility model is sensed by Hall chip, can accurately measure the real time position of engine cam, additionally export low and high level (0～12V), there is measurement accurately, contactless, long service life, the feature such as high-low temperature resistant (-40 DEG C--150 DEG C)；Simple in construction, technical process simply easily realize, and production efficiency is high, vehicle cam shaft position sensor cheap for manufacturing cost.
