Abstract
The utility model discloses a kind of new type of cam shaft position sensor, it is characterised in that including housing, skeleton, the bottom of skeleton is inserted in the enclosure interior, riveting has a groove on the side wall of housing, at the position of the groove, and the madial wall of housing protrudes towards center of circle direction；On horizontal direction corresponding with the groove：There is the space for accommodating the groove on the lateral wall of skeleton, do not contacted between gap housing and skeleton, the axial direction both sides in the space, the lateral wall of skeleton is close to the madial wall of housing.The utility model has the advantage that：By way of riveting groove, forming screens, and in enclosure interior encapsulating, improve structural strength and stability in housing sidewall after assembling.The elastic construction that enclosure interior is installed contributes to be fastened on chip into the bottom of housing again.
Description
Technical field
The utility model is related to automobile sensor correlative technology field, and in particular to a kind of novel camshaft position sensing
Device.
Background technology
CMPS Camshaft Position Sensor is a kind of sensor for being used to detect vehicle cam shaft position, instantly hall sensor
Technology is the most ripe, gathers sensor chip by Hall effect and outputs signal to ECU, so as to realize the smooth point of automobile
Fire.However, the CMPS Camshaft Position Sensor of existing conventional design is fastening type structure, intubating length is high, is easily damaged internal device
Part, if insertion is too short, and easily produces gap.
Utility model content
The purpose of this utility model is to improve structural stability there is provided a kind of to make up the deficiencies in the prior art
New type of cam shaft position sensor.
In order to reach the purpose of this utility model, technical scheme is as follows：
A kind of new type of cam shaft position sensor, it is characterised in that including housing, skeleton, the bottom of skeleton is inserted in described
Enclosure interior, riveting has a groove on the side wall of housing, at the position of the groove, and the madial wall of housing is towards the center of circle
Protrude in direction；On horizontal direction corresponding with the groove：There is the space for accommodating the groove, in sky on the lateral wall of skeleton
Do not contacted between housing and skeleton at gap, the axial direction both sides in the space, the lateral wall of skeleton and the madial wall of housing
It is close to.
Preferably, in addition to FPC components, chip, exterior seal ring, contact pin and reinforcing ring, one loading enclosure interior of skeleton
And equipped with three contact pins inside other end, contact pin passes through whole skeleton, and one end of contact pin is connected with FPC components, and FPC components are fixed
It is connected in enclosure interior and with chip, chip is arranged on the bottommost of enclosure interior, described exterior seal ring is arranged on outside housing
Side.
Preferably, silicone filler is used in described enclosure interior gap.
Preferably, the skeleton is provided with elastic construction, and elastic construction is to ensure bottommost of the chip top pressure in housing.
The utility model has the advantage that：
By way of riveting groove, forming screens in housing sidewall after assembling, and in enclosure interior encapsulating, improve
Structure strength and stability.The elastic construction that enclosure interior is installed contributes to be fastened on chip into the bottom of housing again.

Fig. 3 is the lateral cut-away illustration of the utility model CMPS Camshaft Position Sensor.
Fig. 4 be in Fig. 3 A-A to cut-away illustration.
Embodiment
The utility model is further described with reference to embodiment, but protection domain of the present utility model not only office
It is limited to embodiment.
With reference to shown in Fig. 1-Fig. 4, a kind of new type of cam shaft position sensor, it is characterised in that including housing 1, skeleton 2,
FPC components 3, chip 4, exterior seal ring 5, contact pin 6 and reinforcing ring 7, reinforcing ring 7, which is arranged on housing 1, to be used to strengthen total
Intensity.Housing 1, which is integrated, to be molded and for interior hollow round column shape, and the bottom of skeleton 2 is arranged in housing 1.Skeleton 2 is one
Body is molded and as generally L-shaped.
Contact pin 6 passes through whole skeleton 2, and one end of contact pin 6 is connected with FPC components 3, and FPC components 3 are fixed on inside housing 1
And be connected with chip 4, chip 4 is arranged on the bottommost inside housing 1, and described exterior seal ring 5 is arranged on the outside of housing 1.
Filled at the internal voids of housing 1 with silica gel 8.The skeleton 2 is provided with elastic construction 9, and elastic construction 9 is to protect
Demonstrate,prove bottommost of the top pressure of chip 4 in housing 1, it is ensured that the stability of the corrosion-resistant anti-vibration resistance of sensor internal and structure.
Riveting has a groove 10 on the side wall of housing 1, at the position of the groove 10, the madial wall court of housing 1
Protruded to center of circle direction.With on the corresponding horizontal direction of the groove 10：Have on the lateral wall of skeleton 2 and accommodate the groove
Space 11, do not contacted between housing 1 and skeleton 2 at space 11.Axial direction both sides (i.e. on Fig. 4 in the space 11
Lower direction both sides), the lateral wall of skeleton 2 is close to the madial wall of housing 1, the groove formation screens after riveting, can make bone
Frame is secured firmly to enclosure interior without departing from out of housing.
Finally it should be noted that：Above example only not limits the utility model and retouched to illustrate the utility model
The technical scheme stated, therefore, although this specification the utility model is had been carried out with reference to each above-mentioned embodiment it is detailed
Illustrate, still, it will be understood by those within the art that, still the utility model can be modified or equally replaced
Change, and technical scheme that all do not depart from spirit and scope of the present utility model and its improvement, it all should cover new in this practicality
In the right of type.
