Abstract

The utility model relates to an engine oil pressure sensor, which belongs to the technical field of pressure alarms, and mainly solves the problems that an existing exposed conducting inserting piece is easily oxidized to cause insufficient contact, alarm flash and even failure, and alarm points are easy to change in use process. The engine oil pressure sensor is mainly characterized by comprising a casing assembly, a spring seat, a measuring spring and an end button; the casing assembly includes a casing, a sealing gasket, a film, a top core, a pressing plate and a washer for fixing the top core; the end button and a conducting inserting piece are integrally formed into an end button inserting piece assembly in an injection molding manner; and the casing assembly is arranged between the film and the spring seat. The engine oil pressure sensor has the advantages of avoidance of oxidization of the conducting inserting piece, stable alarm points and high reliability, and is mainly used for realizing alarm when the engine oil pressure of an automobile is over-low.

Description

Oil pressure sensor
Technical field
The utility model belongs to the pressure alarm technical field.Be specifically related to the machine oil hydraulic that a kind of automobile uses and cross the low oil pressure sensor of realizing warning function.
Background technique
At present, the oil pressure that uses on the automobile is crossed low alarm sensor as shown in Figure 4, is made up of housing 16, spring seat 18, measuring spring 14, rubber washer 21, diaphragm 20, adjusting top board 12, aluminium ring 15, pressing plate 19, terminal assembly 13.Wherein, electric interfaces partly is to adopt screw assemblies 11 to be fixed on the terminal assembly.The inserted sheet 17 that directly will conduct electricity when entrucking is fixed on the screw assemblies 11.Such sensor causes conducting electricity the inserted sheet oxidation easily and contacts insufficiently owing to the conduction inserted sheet exposes, cause report to the police flicker even lost efficacy of sensor.While is adjusted by adjusting top board 2 owing to its alarm point and is fixing with varnish, so in use occur the phenomenon of alarm point change easily.
Summary of the invention
The purpose of this utility model is exactly to cross low alarm sensor deficiency and a kind of oil pressure sensor that inserted sheet can be not oxidized, alarm point is reliable and stable that conducts electricity is provided at existing oil pressure.
Technical solution of the present utility model is: a kind of oil pressure sensor, be contained on the motor car engine main oil pipe road, comprise housing assembly, spring seat, measuring spring, terminal, conduction inserted sheet, housing assembly comprises housing, rubber washer, diaphragm, it is characterized in that: with described terminal, conduction inserted sheet integral molded plastic and constitute terminal inserted sheet assembly; Also comprise plunger tip in the housing assembly and fix the pressing plate and the pad of this plunger tip, be arranged between diaphragm and the spring seat.
Terminal inserted sheet assembly described in the technical solution of the utility model is formed by standard terminal, conduction inserted sheet integral molded plastic, and terminal is the plug receptacle of water proof and dust proof, and material is PA66 30%GF plastics.
Seal washer described in the technical solution of the utility model adopts the resistant to elevated temperatures fluorosioloxane rubber material of oil resistant to make.
Housing described in the technical solution of the utility model adopts easy cutting structural carbon steel to make, and the surface is provided with zinc coat.
Diaphragm described in the technical solution of the utility model adopts polyimide 6050 diaphragms.
Plunger tip described in the technical solution of the utility model adopts PA66 30%GF material to make.
Pressing plate described in the technical solution of the utility model, pad, spring seat adopt the carbon constructional quality steel Cold Rolled Sheet Steel to make.
Measuring spring described in the technical solution of the utility model adopts piano wire to make.
The utility model is owing to described terminal, conduction inserted sheet integral molded plastic are constituted terminal inserted sheet assembly, and in housing assembly, increase plunger tip and fix the pressing plate and the pad of this plunger tip, be arranged between diaphragm and the spring seat, thereby realized that the coupling connector assembly carries out ways of connecting, internal structure can not be adjusted, so not only connect reliably, the conduction inserted sheet can be not oxidized, and alarm point is stable.The seal washer that the utility model is made owing to the resistant to elevated temperatures fluorosioloxane rubber material of employing oil resistant, thereby have the good characteristics of compressive strain.The utility model is owing to adopt polyimide 6050 diaphragms, thereby has good temperature resistance and stable mechanical property.The utility model is owing to adopt the carbon constructional quality steel Cold Rolled Sheet Steel to make pressing plate, pad, spring seat, thereby has toughness height, the good characteristics of cold stamping.
The utility model has overcome the defective that existing oil pressure is crossed low alarm sensor, has the advantages that the conduction inserted sheet can be not oxidized, alarm point is reliable and stable.The utility model is mainly used in the machine oil hydraulic of realizing automobile and crosses warning when low.

Fig. 2 is the general structure schematic representation plan view of the utility model oil pressure sensor;
Fig. 3 is the housing assembly structural representation of the utility model oil pressure sensor;
Oil pressure commonly used is at present crossed the general structure schematic representation of low alarm sensor during Fig. 4.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3.Oil pressure sensor is made of housing assembly 4, spring seat 3, measuring spring 2 and terminal inserted sheet assembly 1.Housing assembly 4 comprises housing 7, seal washer 6, diaphragm 10, plunger tip 8, pressing plate 5 and pad 9.Terminal inserted sheet assembly 1 is formed by terminal, conduction inserted sheet integral molded plastic.Housing 7 adopts easily cutting structural carbon steel, and the surface is provided with zinc coat.Plunger tip 8 adopts PA66 30%GF plastics to make.Pressing plate 5, pad 9, spring seat 3 adopt the carbon constructional quality steel Cold Rolled Sheet Steel to make.
Diaphragm 10 on the sensor produces distortion with the height of oil pressure and replys, and its deformation promotes measuring spring 2 to-and-fro motion by plunger tip 8 and spring seat 3, contact closed and disconnecting when being implemented in predetermined pressure, thus realize the function of reporting to the police.Diaphragm 10 adopts polyimide 6050 diaphragms, and the oil leakage fault that traditional rubber folder cloth diaphragm occurs can not appear in sensor internal.
Pressing plate 5 compresses by the interference fit of pad 9 with housing 7, with the guiding and the stroke of control plunger tip 8, and utilizes 6 pairs of diaphragms 10 of seal washer to seal.Seal washer 6 adopts the resistant to elevated temperatures fluorosioloxane rubber material of oil resistant to make.
Be injection-moulded in the international standard that terminal inserted sheet assembly 1 top terminal has adopted water proof and dust proof, material is PA66 30%GF plastics, and SICMA2 is good fit with sheath, can improve reliability, water proof and dust proof.Terminal inserted sheet assembly 1 has the reliable and easy accessibility of connection, highly versatile.
The utility model oil pressure sensor, its alarm point need not adjusted, and realizes that this requirement mainly contains the improvement of two aspects.The one, the accurate Calculation of measuring spring and a large amount of checking determine that the various parameters of spring are the keys that the sensor realization need not be regulated.The 2nd, this sensor has increased the hold down gag of diaphragm, sees accompanying drawing 3.Diaphragm 10 adopts the polyimide diaphragm, and its thickness has only 0.08mm, and the dimensional accuracy height, like this to the essentially no influence of the stroke of spring, just can satisfy the function that predetermined alarm point is reported to the police thereby can realize need not adjusting stroke.
The utility model oil pressure sensor, electric interfaces adopt terminal inserted sheet assembly, have to connect reliable and easy accessibility, highly versatile.
