Abstract
An engine oil pressure alarm sensor comprises a housing, a tubular spring, a movable contact, a stationary contact, a binding post and a pipe joint, wherein the pipe joint is arranged at the bottom of the housing, the tubular spring is arranged in the housing, one end of the tubular spring is communicated with a lubrication system main oil gallery through the pipe joint, the other end of the tubular spring is connected with the movable contact, the binding post is arranged at the upper end of the housing, the stationary contact is placed at the tail end of the binding post, and the movable contact is located above the stationary contact. When engine oil pressure is low, deformation of the tubular spring is small, the movable contact and the stationary contact are closed, an electric circuit is closed, and a warning lamp shines. When the engine oil pressure is normal, elastic deformation generated by the tubular spring is large, the movable contact and the stationary contact are disconnected, the electric circuit is cut off, and the warning lamp is turned off. The engine oil pressure alarm sensor has the advantages of being simple in structure, excellent in performance, safe and reliable and the like.
Description
Technical field
The utility model belongs to automobile equipment field, is specifically related to a kind of machine oil pressure warning sensor.
Background technique
In the time that the engine oil pressure of motor is in improper scope, engine oil pressure alarm sends alarm signal.Engine oil pressure alarm of the prior art, mainly exists defect to be, the extending means in alarm, after long period operation, is prone to movable inefficacy, thereby causes sending alarm signal, to such an extent as to occur security incident.
Model utility content
In order to solve the technical problem existing in prior art, the purpose of this utility model is to provide a kind of engine oil pressure alarm sensor of simple in structure, function admirable.
The technical solution adopted in the utility model is as follows:
Machine oil pressure warning sensor, by housing, tubular spring, movable contact, stationary contact, wiring terminal and pipe joint.
Described housing bottom is provided with pipe joint, has a tubular spring in housing, and tubular spring one end communicates with lubricating system main oil gallery through pipe joint, and the other end is connected with movable contact.
Described housing upper end portion is provided with wiring terminal, and described stationary contact is placed in wiring terminal end, makes movable contact in stationary contact top.
In the time that engine oil pressure is too low, tubular spring distortion is very little, makes movable contact and stationary contact closure, and circuit is connected, and makes emergency warning lamp shinny; In the time that engine oil pressure is normal, the resiliently deformable that tubular spring produces is large, and movable contact and stationary contact are disconnected, circuitry cuts, and emergency warning lamp extinguishes.
The utility model has the advantage of: simple in structure, function admirable, safe and reliable etc.
Brief description of the drawings
Fig. 1 is complete section structural representation of the present utility model.
Wherein: 1. housing, 2. tubular spring, 3. movable contact, 4. stationary contact, 5. wiring terminal, 6. pipe joint.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, machine oil pressure warning sensor, by housing 1, tubular spring 2, movable contact 3, stationary contact 4, wiring terminal 5 and pipe joint 6 for the utility model.
Described housing 1 bottom is provided with pipe joint 6, has a tubular spring 2 in housing 0, and tubular spring 2 one end communicate with lubricating system main oil gallery through pipe joint 6, and the other end is connected with movable contact 3.
Described housing 0 upper end portion is provided with wiring terminal 5, and described stationary contact 4 is placed in wiring terminal 5 ends, makes movable contact 3 in stationary contact 4 tops.
When engine oil pressure is lower than 0.05～0.09MPa (0.6～1.0kgf/cm
2) time, tubular spring 2 is out of shape very little, makes movable contact 3 and stationary contact 4 closures, and circuit is connected, and makes emergency warning lamp shinny, points out that main oil gallery engine oil pressure is too low, in time shutdown maintenance; In the time that engine oil pressure exceedes 0.05～0.09MPa, the resiliently deformable that tubular spring 2 produces is large, and movable contact 3 and stationary contact 4 are disconnected, circuitry cuts, and emergency warning lamp extinguishes, and illustrates that lubricating system is working properly.
