Abstract
The utility model relates to an air filter blocking warning sensor and belongs to the technical field of air filter blocking warning sensors. The air filter blocking warning sensor mainly solves the problem that most of existing air filter blocking warning sensors are in a normally open type, designs a normally closed type air filter blocking warning sensor, and provides one more selection scheme of finished automobile circuit design for customers. The air filter blocking warning sensor is mainly characterized by comprising an electric plug sheet, a flat washer, a sealing washer, a regulating plug screw, a locking nut, a spring washer, a shell body, a diaphragm assembly and a measuring spring, and further comprises a terminal assembly which is formed as a whole by a conducting rod and an injection molding body. The injection molding body is provided with a terminal groove, the diaphragm assembly comprises a conducting sheet, a semi-hollow rivet, an O-shaped ring and a diaphragm pressing rivet, and the terminal assembly, the diaphragm assembly and the sealing washer are arranged in the shell body. The air filter blocking warning sensor has the advantages of being compact in structure, light, long in service life of the product and high in work reliability. The air filter blocking warning sensor is mainly used for automatically detecting whether the air filter of a car is blocked and sending out alarming signals in real time.
Description
Technical field
The utility model belongs to air filter and blocks the alarm sensor technical field.Be specifically related to a kind of sensor unit that whether blocks and send in real time alarm signal for air filter on the automatic detection automobile.
Background technique
At present, the air filter of using on the automobile is blocked alarm sensor and is mainly contained two kinds of patterns: open in usual and Normally closed type.The concrete circuit layout that uses any needs to look car load decides, and existing air filter is blocked alarm and mostly is open in usual; The utility model is Normally closed type, for the vehicle complete vehicle circuit layout provides many a kind of selections.
Existing Normally closed type air filter is blocked alarm sensor and is comprised conductive insert, plain washer, seal washer, adjusting plug screw, locking nut, spring washer, housing, diaphragm assembly, measuring spring, because not by the injection molded terminal assembly of electric-conducting stem, easily loosening after the long-time use of conductive insert; The conventional construction diaphragm drives plunger tip promotion spring and easily causes the force value loss.
Summary of the invention
The purpose of this utility model is exactly to block alarm sensor for present air filter to open and close form and provide a kind of compact structure, lightweight, long product lifecycle and the good air filter of functional reliability to block the alarm sensor assembly.
Technical solution of the present utility model is: a kind of air filter is blocked the alarm sensor assembly, comprise conductive insert, plain washer, seal washer, adjusting plug screw, locking nut, spring washer, housing, diaphragm assembly, measuring spring, it is characterized in that: also comprise by electric-conducting stem and injection molding body forming whole terminal assembly, the axial side end face of this injection molding body is provided with the terminal groove; The diaphragm assembly is pressed and is consisted of by conducting plate, semitubular rivet, O type circle, diaphragm; Terminal assembly, diaphragm assembly, seal washer are loaded in the housing.
Injection molding body described in the technical solution of the present utility model is provided with the vent that communicates with the terminal groove.
The utility model is owing to adopt the air filter that is made of conductive insert, plain washer, terminal assembly, seal washer, adjusting plug screw, locking nut, spring washer, housing, diaphragm assembly, measuring spring to block alarm sensor, after being contained on the car load, car load air pressure promotes the diaphragm assembly and moves axially, thereby drive the contact of semitubular rivet and electric-conducting stem or separate to realize the closed of sensor unit or disconnect that the warning light on this closure or the cut-off signal access vehicle circuitry operating board is to the running state of driver's output display air filter.Owing in sensor mechanism, be provided with seal washer and O type circle, thereby realize the partition between car load end air pressure and the atmospheric pressure, so that diaphragm assembly drive semitubular rivet under the ordering about of car load negative pressure moves axially.Thereby vent has been avoided because the alarm drifting problem that sensor self the internal cavity pressure change that the variation of serviceability temperature causes causes owing to be provided with in the terminal assembly.Owing to adopted the adjusting screw plug structure, adjustable sensor is realized warning function under different force value, enlarged adaptability and the applicable scope of assembly.Owing to adopted standard-sized conductive insert, so that car load is quick and easy for installation.The utlity model has compact structure, the moderate long product lifecycle of weight and the high characteristics of functional reliability.The utility model is to be mainly used in automatically detecting the sensor that alarm signal is blocked and sent in real time to the automobile air filter whether.

Embodiment
Extremely shown in Figure 5 such as Fig. 1.The utility model is comprised of conductive insert 1, plain washer 2, terminal assembly 3, seal washer 4, adjusting plug screw 5, locking nut 6, spring washer 7, housing 8, diaphragm assembly 9, measuring spring 10.Terminal assembly 3 realizes that by mold injection molding injection molding body 12 axial side end faces are provided with the terminal groove together by electric-conducting stem 11 and injection molding body 12.Conductive insert 1 is fixed on the electric-conducting stem 11 by plain washer 2, spring washer 7, locking nut 6.Diaphragm assembly 9 is pressed by press by conducting plate 14, semitubular rivet 15, O type circle 16, diaphragm 17 and forms.Combination between terminal assembly 3 and the housing 8 realizes by press riveting limit.Combination between terminal assembly 3 and the housing 8 realizes by press riveting limit.Diaphragm assembly 9 and terminal assembly 3 are at the complete rear formation sensor inner chamber of general assembly, the terminal groove upper end of terminal assembly 3 arranges an axial vent 13, realize that sensor inner chamber and barometric pressure communicate, avoid because the inner chamber atmospheric pressure value that temperature causes changes the alarm point drift that brings.Regulating plug screw 5 adopts screw pair to be combined with housing 8.The precompressed amount of the position regulation measuring spring 10 by regulate regulating plug screw 5, thus realize that sensor connects alarm signal when different force value.Diaphragm assembly 9 is realized car load end air pressure and external atmospheric isolation, and when there are pressure difference in car load mounting hole place's air pressure and external barometric pressure, drive semitubular rivet 15 motions, realize with the contact of electric-conducting stem 11 or separate then conducting or disconnect the output of sensor alarm signal.
Operating voltage is that 12/24V is general, measures accurately, is subjected to the impact of external environment less, stable performance.Highly versatile can become according to the height design of the requirement of car load the sensor of different pressures alarm point, satisfies user's needs.
