Description
Technical field
The utility model belongs to engine oil pressure monitoring technical field, is specifically related to a kind of sensor unit for automatically monitoring oil pressure of automobile engine.
Background technique
At present, sensor for monitoring engine oil pressure on automobile mainly contains two kinds by output signal point: a kind of is export the sensor for continuous voltage signal, another kind is output is the sensor that a road continuous resistance signal adds a way switch, the cost of these two kinds of sensors is higher, and also needs the follow-up program of motormeter to judge to determine that whether engine oil pressure is normal again.
Summary of the invention
The utility model provides a kind of output to be the sensor of a way switch, cost is lower, directly can be connected in series tutorial light in order to point out driver's engine oil pressure whether normal in instrument, has the advantages that product structure exquisiteness, long service life and reliable long-term working are good.
Technical solution of the present utility model is: a kind of oil pressure sensor assembly, is characterized in that: be made up of housing assembly, lower spring cup, measuring spring, terminal assembly; Wherein, housing assembly is made up of housing, seal washer, diaphragm, pressing plate, plunger tip, seal washer, diaphragm, pressing plate, plunger tip are pressed and are fixed in housing chamber, pressing plate is circular, recessed to side in the middle part of pressing plate, and recessed face is provided with through hole, the side of plunger tip and film contact, the opposite side of plunger tip passes from the through hole of pressing plate; Terminal assembly is made up of inserted sheet, terminal housing, and inserted sheet is fixed in terminal housing, and terminal assembly press seal is on housing assembly; Lower spring cup is loaded on plunger tip by the through hole at center; Measuring spring is between lower spring cup and inserted sheet, and the side of plunger tip penetrates in measuring spring.
Terminal assembly described in technical solution of the present utility model by inserted sheet, engineering plastics PA6630%GF through injection molded.
The utility model is owing to adopting by housing assembly, lower spring cup, measuring spring, the oil pressure sensor assembly of terminal assembly composition, and seal washer, diaphragm, pressing plate, plunger tip is pressed to be fixed in housing chamber and is formed housing assembly, terminal assembly is by inserted sheet, terminal housing forms, and press seal is on housing assembly, measuring spring and lower spring cup are between plunger tip and inserted sheet, thus diaphragm can preferably by machine oil and the isolation of electric measurement part, the housing entirety mode of pressing makes sealability of the present utility model, reliability is largely increased, and can ensure that diaphragm is not depressed into permanent deformation in the process of pressing, measuring spring is used for the displacement that switching to pressure is corresponding lower spring cup, control the conducting between lower spring cup and pressing plate, and then control the conducting of sensor, disconnect.
The utility model have compact structure, average weight, without the high feature of the defect such as oil impregnate or leakage of oil, long product lifecycle and functional reliability.The utility model is mainly used in the sensor of automatically monitoring oil pressure of automobile engine.

Fig. 2 is the sectional view of the housing assembly structure of the utility model oil pressure sensor assembly.
Fig. 3 is the sectional view of the utility model oil pressure sensor terminal assembly.
Fig. 4 is that the housing assembly of the utility model oil pressure sensor assembly presses front cross sectional view.
Fig. 5 is sectional view after the housing assembly of the utility model oil pressure sensor assembly presses.
Embodiment
As shown in Figures 1 to 5.The utility model is made up of housing assembly 1, lower spring cup 2, measuring spring 3, terminal assembly 4.Housing assembly 1 is made up of housing 5, seal washer 6, diaphragm 7, pressing plate 8, plunger tip 9.Terminal assembly 4 is made up of terminal housing 10, inserted sheet 11.
Seal washer 6, diaphragm 7, pressing plate 8, plunger tip 9 are pressed be fixed in housing chamber through assembly process, the operations that presses.Pressing plate 8 is circular, recessed to side in the middle part of pressing plate 8, flare, and recessed face is provided with through hole.The side of plunger tip 9 contacts with diaphragm 7, and the opposite side of plunger tip 9 passes from the through hole of pressing plate 8, and is fixed by pressing plate 8 at step place.Housing assembly 1 operation that presses realizes sealing by pressing to housing entirety and ensure that diaphragm 7 is not depressed into permanent deformation.Diaphragm 7 is for isolating machine oil and electric measurement part.Terminal assembly 4 is by inserted sheet 11, engineering plastics PA6630%GF through injection molded, and inserted sheet 11 is fixed in terminal housing 10, and terminal assembly 4 press seal is on housing assembly 1, and the electric connecting member of terminal assembly 4 meets the requirement of IP67 protective.Lower spring cup 2 is loaded on plunger tip 9 by the through hole at center.Measuring spring 3 is between lower spring cup 2 and inserted sheet 11, and the side of plunger tip 9 penetrates in measuring spring 3.Measuring spring 3 is the displacement of corresponding lower spring cup 2 for switching to pressure, controls the conducting between lower spring cup 2 and pressing plate 8, and then controls conducting, the disconnection of sensor.
After sensor base oilhole passes into the machine oil of pressure, by diaphragm 7, pressure is passed to measuring spring 3, pressure is converted to the displacement of lower spring cup 2 by measuring spring 3, then controls the conducting between lower spring cup 2 and pressing plate 8, disconnection, realizes the switch control rule of sensor.When engine oil pressure is too low, sensor conducts, the warning light connected in instrument informs that driver's engine oil pressure is abnormal.
Operating voltage is that 12/24V is general, and measure accurately, the impact by external environment is less, stable performance.Highly versatile, can become the sensor of different installation form, meet user's needs according to motor Interface design.
