Description
Technical field
The utility model relates to field of automobile parts and components, specially a kind of novel vehicle speed sensor.
Background technique
Sensor structure before is injection molding type, since interiors of products has a circuit board, in order to which protection circuit plate is being infused
It is not damaged when modeling, can all carry out on circuit boards playing encapsulating protection before injection molding, even if in this way, being still suffered from after injection molding certain
The defective products of ratio is primarily present following disadvantage:
1. need to beat casting glue before injection molding, operate it is cumbersome, and beat after casting glue still to wait glue curings after could be after
Continuous production, the production cycle is long, low efficiency；
2. it is high for equipment and technology parameter request when injection molding, if injection pressure is bigger than normal or the injection time is partially long, still
A certain proportion of defective products, unstable product quality are had, and the product that an amount is made is defective in quality, then product will not
It can be carried out and do over again, circuit board can only be scrapped together with chip, high production cost.
Utility model content
It is mentioned above in the background art to solve the purpose of this utility model is to provide a kind of novel vehicle speed sensor
Problem.
To achieve the above object, the utility model provides the following technical solutions: a kind of novel vehicle speed sensor, including circuit
It board mount, O-ring seal, sensing head housing, circuit board, chip and buckles a little, the fixed peace in the positive bottom of circuit board support
Equipped with the chip, the surface of the chip is equipped with the circuit board, the back side of the circuit board and the circuit board support
Front be welded to connect, the circuit board support is arranged with the O-ring seal, the circuit close to one end of the circuit board
The bottom of board mount is arranged with the sensing head housing.
As a kind of optimal technical scheme of the utility model, the O-ring seal is made of rubber material.
As a kind of optimal technical scheme of the utility model, the circuit board support passes through the button point and the sensing
Head housing is fixedly connected.
As a kind of optimal technical scheme of the utility model, the circuit board is electrically connected the chip.
Compared with prior art, the utility model has the beneficial effects that the utility model 1. eliminates gluing process, save
Cured time after gluing, simple production process, high production efficiency；
2. Improving The Quality of Products, using novel structure, chip not will receive the influence of injection pressure, product with circuit board
Quality is stablized；
3. as fruit product make it is rear defective in quality, it is easy to operate then product development can be done over again, and core
Piece is unaffected with circuit board, reduces cost.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the schematic cross-sectional view of the utility model；
In appended drawing reference: 1. circuit board supports；2.O type sealing ring；3. sensing head housing；4. circuit board；5. chip；6. button
Point.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of novel vehicle speed sensor, including circuit board support 1, O-shaped sealing referring to FIG. 1-2,
Circle 2, sensing head housing 3, circuit board 4, chip 5 and buckle a little 6, the positive bottom of circuit board support 1 is fixedly installed with chip 5, core
The surface of piece 5 is equipped with circuit board 4, and the back side of circuit board 4 and the front of circuit board support 1 are welded to connect, and circuit board support 1 leans on
One end of nearly circuit board 4 is arranged with O-ring seal 2, and the bottom of circuit board support 1 is arranged with sensing head housing 3.
Preferably, O-ring seal 2 is made of rubber material, and sealing effect is preferable.
Preferably, circuit board support 1 is fixedly connected by button point 6 with sensing head housing 3, makes circuit board support 1 and sensing
Head housing 3 buckles labor, uses relatively stable.
Preferably, circuit board 4 is electrically connected chip 5.
Working principle: first circuit board 4 is welded on circuit board support 1, chip 5 is then assembled to circuit board support 1
On, then O-ring seal 2 is assembled between the top of sensing head housing 3 and circuit board support 1, such as the mark position in Fig. 2,
Play the role of waterproof sealing, last sensing head housing 3 is assembled with circuit board support 1, by button point 6, circuit board branch
1 component of frame is fixed together with sensing head housing 3, and product can be produced and be finished, and eliminates gluing process, consolidates after saving gluing
The time of change, simple production process, high production efficiency, Improving The Quality of Products, using novel structure, chip and circuit board will not
Influenced by injection pressure, stable product quality, as fruit product make it is rear defective in quality, then can product development into
Row is done over again, easy to operate, and chip is unaffected with circuit board, reduces cost.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
