Abstract
The utility model discloses a kind of pressure sensor, including sensor housing and bonnet and valve, the valve and bonnet are each provided on sensor housing, the sensor housing is provided with protruding circular ring, described valve one end is provided with cylindrical structure, and the cylindrical structure interference fit of the valve, which is enclosed on protruding circular ring, to be weldingly connected.Pressure sensor structure is reasonable in design, is welded after being interference fitted between valve and sensor housing by lf, welds efficient stable, improves the sealing property at cooperation, pulling-out force is also strengthened after connection so that product safety is reliable, fault rate is low.
Description
Technical field
Automotive sensor technology field is the utility model is related to, more particularly, to a kind of pressure sensor.
Background technology
Most of existing car force sensor be all using epoxy resin by the valve of sensor and case bonding,
Viscose glue of having a rest coordinates, this coordinate shortcoming between viscose glue easy gas leakage, come off and production process time-consuming, it is low production efficiency, easy to aging
Come off, quality it is unstable.
Utility model content
In view of the shortcomings of the prior art, technical problem to be solved in the utility model is to provide a kind of pressure sensor, with
It is easy to reach production, the purpose of sealed reliable.
In order to solve the above-mentioned technical problem, technical scheme is used by the utility model：
The pressure sensor, including sensor housing and bonnet and valve, the valve and bonnet are each provided at sensor
On housing, the sensor housing is provided with protruding circular ring, and described valve one end is provided with cylindrical structure, the cylinder knot of the valve
Structure interference fit, which is enclosed on protruding circular ring, to be weldingly connected.
Further, it is described to be welded as laser welding.
The open end of the protruding circular ring is provided with arc angling.
The outer rim of the open end of the protruding circular ring is provided with excessive glue groove.
The bonnet is the box like structure provided with opening, is determined between the side of box like structure and sensor housing by clamp
Position.
The excessive glue groove is annular groove.
The utility model compared with prior art, has advantages below：
The pressure sensor structure is reasonable in design, is welded after being interference fitted between valve and sensor housing by lf
Connect, weld efficient stable, improve the sealing property at cooperation, pulling-out force is also strengthened after connection so that product safety is reliable, failure
Rate is low.
Brief description of the drawings
The content expressed by each width accompanying drawing of this specification and the mark in figure are briefly described below：
Fig. 1 is the utility model pressure sensor structure schematic diagram.
Fig. 2 is the utility model pressure sensor exploded perspective view.
Fig. 3 is the utility model pressure sensor partial schematic diagram.
In figure：
1. sensor housing, 2. valves, 3. bonnets, 4. circuit boards, 5. barrier films, 6. excessive glue grooves.
Embodiment
Below against accompanying drawing, by the description to embodiment, specific embodiment of the present utility model is made further detailed
Thin explanation.
As shown in Figure 1 to Figure 3, the pressure sensor, including sensor housing 1 and bonnet 3 and valve 2, valve 2 is with after
Lid 3 is each provided on sensor housing 1.
Sensor housing 1 is provided with protruding circular ring, and the one end of valve 2 is provided with cylindrical structure, and the cylindrical structure interference of valve 2 is matched somebody with somebody
Trap, again by being welded and fixed, is provided with barrier film 5 on the protruding circular ring of sensor housing in protruding circular ring, for unidirectional in housing
Valve seals；Preferably, laser welding is welded as, plastic contact surface is melted by heat caused by laser beam and then is bonded in one
Rise, good seal performance, efficiency high.
The open end of protruding circular ring is provided with arc angling, is easy to the cylindrical structure of valve to be enclosed on protruding circular ring, installation
It is easy to operate.
Bonnet 3 is the box like structure provided with opening, is positioned between the side of box like structure and sensor housing by clamp,
The circuit board 4 being located in sensor housing is covered by bonnet 3；Installation operation is easy, and maintenance easy to disassemble.
The outer rim of the open end of protruding circular ring is provided with excessive glue groove 6, it is preferred that excessive glue groove 6 is annular groove；Laser Welding
Contact surface melts when connecing, and the setting of excessive glue groove prevents the plastics outflow of fusing, and the setting of excessive glue groove can improve sealing effectiveness
With raising pulling-out force.
The utility model is exemplarily described above in conjunction with accompanying drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, as long as employing the improvement of the various unsubstantialities of design of the present utility model and technical scheme progress,
Or it is not improved by it is of the present utility model design and technical scheme directly apply to other occasions, in guarantor of the present utility model
Within the scope of shield.
