Description
Technical field
The utility model is related to automotive field more particularly to a kind of crankshaft position sensors.
Background technology
The modernization of electron controls technology so that the electric control field of automobile develops rapidly, and sensor is that connection with automotive vehicles is each
The hinge of the action of a part and state and auto electric control, is the input information of automobile electric control system, is the pass on automobile
The research core of key member and automotive electronic technology.
However, in actual production, because of the limitation of technique and technology, still can there is different problems.As shell is consolidated
Periodically, often shell is damaged by pressure due to coupling mechanism force is too big.
Utility model content
The purpose of this utility model is to be directed to above-mentioned present situation, provide it is a kind of it is simple in structure, stable and reliable for performance, install and use
Convenient and long-lived crankshaft position sensor.
The technical solution adopted in the utility model：A kind of crankshaft position sensor, including it is contact pin component, bucket, embedded rings, outer
Shell and sealing ring, and the contact pin component, bucket, embedded rings and the shell injection molding, the sealing ring are sheathed on described outer
The periphery of shell, the embedded rings injection molding packaging is in the shell；One end resin of the contact pin component is potted in the bucket, separately
For one end injection molding packaging in the shell, the contact pin component includes contact pin, pcb board, holder and magnet, and the pcb board is fixed
On the bracket, the contact pin is welded on the pcb board, and the magnet is fixed on the bracket, the embedded rings
Upper and lower two contact surface protrudes from the upper and lower surface of the shell.
The effect of the utility model is：The crankshaft position sensor is simple in structure, stable and reliable for performance, the side of installing and using
Just, and it is durable.
Description of the drawings
Fig. 1 is the assembling figure for the crankshaft position sensor that the utility model embodiment provides.
Fig. 2 is the diagrammatic cross-section of Fig. 1.
Specific implementation mode
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining this practicality
It is novel, it is not intended to limit the scope of the utility model.
Referring to Fig. 1, be a kind of crankshaft position sensor provided by the utility model comprising contact pin component 1, bucket 2, it is embedding
Enter ring 3, shell 4 and sealing ring 5.And contact pin component 1, bucket 2, embedded rings 3 and 4 injection molding of shell, sealing ring 5 are sheathed on outer
The periphery of shell 4.3 injection molding packaging of embedded rings is in shell 4；One end resin of contact pin component 1 is potted in bucket 2, other end injection sealed
In shell 4.
Contact pin component 1 includes the main kernel portion of contact pin 11, pcb board 12, holder 13 and the composition of magnet 14 and sensor
Point, pcb board 12 is stuck on holder 13, then contact pin 11 is welded on pcb board 12, while magnet 14 is also secured at holder
On 13, they are fitted into together in bucket 2 later, pours resin seal, making them, structure and performance can be steady in working condition
It is fixed to play, form shell 4；Bucket 2 and shell 4, embedded rings 3 are finally made into a complete component together, put on sealing ring 5,
It is thus easy to install and use, while also to ensure that its air-tightness is intact.
In this present embodiment, embedded rings 3 are becket, and two contact surfaces up and down of embedded rings 3 protrude from the upper of shell 4
Lower surface, convenient for preferably sensor is fixed with screw, without by pressure effect with shell 4 on, will not be because of coupling mechanism force too
Shell 4 is damaged by pressure greatly.PCB plates 12 are equipped with Hall chip, and contact pin 11 is welded on pcb board 12.
Two muscle positions have been done in bucket 2 and have formed a card slot, and the holder 13 of contact pin component 1 is packed into bucket along the position of card slot
In 2, installation direction and fixing bracket 13 are thus readily identified, prevents contact pin component 1 tilted in bucket 2, so that influencing to insert
The grafting effect of needle 11 directly hits contact pin 11 curved.
It is sleeved on outside sealing ring 5 in the groove of 4 periphery of sensor outer housing, the lower part of groove is sky, and top is suitable with installation environment
Match, the installation of sealing ring and sensor is convenient in such design, while sealing ring is also less likely to be damaged, and air-tightness can obtain very
Good guarantee.
In this way, crankshaft position sensor provided by the utility model is designed using " hall effect type " principle, it is simple in structure,
It is stable and reliable for performance, easy to install and use and durable.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
