Description
Technical field
The utility model belongs to pressure sensor product technical field, in particular to a kind of pressure sensing of band signal output
Device is mainly used in air suspension distributing valve, plays pressure detection and signal output control action.
Background technique
In the prior art, the distributing valve in AIRMATIC Dual Control, is internally provided with pressure sensor, for detecting distribution
Pressure inside valve.Currently, its general only effect of pressure detection of common pressure sensor and no signal output function, because
This its can only the requirement according to system to air pressure realize the detecting of pressure, the effect without can be carried out signal output control.In addition,
Its volume of pressure sensor in the prior art is big, and assembling is complicated, it has not been convenient to which it is used cooperatively in the distributing valve of suspension
In.
In the distributing valve of AIRMATIC Dual Control, if pressure detection and signal output are controlled and can be provided simultaneously with,
Distributing valve is greatly improved in the air pressure distributional effects of AIRMATIC Dual Control, it is ensured that the safety in utilization of automobile air suspension system and
Unfailing performance.
Therefore, the pressure sensor for researching and developing a kind of band signal output is extremely urgent.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, specifically disclose a kind of pressure sensing of band signal output
There is preferable pressure detection effect and signal to export control effect, it is outstanding to be widely used in air for device, the pressure sensor
In the distributing valve of extension system, it is ensured that safety and reliability when AIRMATIC Dual Control uses, while its is small in size, it is easy to assembly
Fast.
In order to reach above-mentioned technical purpose, the utility model is realized by following technical scheme:
The pressure sensor of band signal output described in the utility model, including upper housing and lower case, the upper housing
Circuit board assemblies and the pressing plate for the circuit board assemblies that are fixed and clamped, the circuit board group are equipped in the space surrounded with lower case
Part is equipped with several contact pin pins, and the pressure sensor chip position of corresponding circuits board group part is equipped with the on the circuit board assemblies
One air inlet, the lower case bottom are equipped with the second air inlet, first air inlet and the connection of the second air inlet.
As the further improvement of above-mentioned technology, it is equipped with sealing ring between the lower case and circuit board assemblies, effectively mentions
High sealing effect.
As the further improvement of above-mentioned technology, described contact pin pin a part is embedded in the inside of lower case and under
Shell integrated injection molding, a part are stretched out from the side of lower case.
As the further improvement of above-mentioned technology, the upper housing two sides are equipped with buckle structure, the lower case
Upper corresponding lateral location also is provided with buckle structure, and the two is engaged by clamping.
Compared with prior art, the utility model has the beneficial effects that
(1) the utility model on circuit board assemblies due to being equipped with several contact pin pins, so that pressure sensor is in addition to tool
Play the role of detecting except pressure, moreover it is possible to have both signal output control action, point of AIRMATIC Dual Control can be widely used in
With in valve, it is ensured that safety and reliability when AIRMATIC Dual Control uses.
(2) pressure sensor described in the utility model, it is small in size, while upper housing and lower case are buckle-type connection sides
Formula is easy to assembly quick.
Detailed description of the invention
The utility model is described in detail in the following with reference to the drawings and specific embodiments:
Fig. 1 is the pressure sensor positive structure schematic of band signal output described in the utility model；

3 pressing plate 4, the circuit board assemblies 3 are equipped with several contact pin pins 5, and described 5 a part of contact pin pin is embedded in lower case 2
Inside and with 2 integrated injection molding of lower case, a part from the side of lower case 2 stretch out.
In the present invention, the pressure sensor chip position of corresponding circuits board group part 3 is set on the circuit board assemblies 3
There is the first air inlet 6,2 bottom of lower case is equipped with the second air inlet 7, and first air inlet 6 and the second air inlet 7 connect
It is logical.
In the present invention, it is equipped with sealing ring 8 between the lower case 2 and circuit board assemblies 3, effectively improves sealing effect
Fruit.
In addition, as shown in Figure 3, Figure 4,1 two sides of upper housing are equipped with buckle structure 11, it is right in the lower case 2
The lateral location answered also is provided with buckle structure 21, and two buckle structure 11 and 21 is firm by upper housing 1 and lower case 2 after being engaged by clamping
Solid assembling, while be engaged by clamping structure be also convenient for detachable maintaining, it is easy to use.
The utility model is not limited to above embodiment, and all various changes or modifications to the utility model do not take off
Spirit and scope from the utility model, if these modification and variations belong to the claims and equivalents of the utility model
Within the scope of, then the utility model is also implied that comprising these modification and variations.
