Abstract
The utility model discloses a contact micro vibration sensor, which is mainly composed of an insulating shell, an electrode, a conductive body and a monostable trigger. The utility model has the advantages of reliable performance, simple structure, small size and low cost. The contact micro vibration sensor is suitable for a plurality of fields such as the machinery, the meter, the domestic appliance, etc.
Description
The utility model is a kind of little vibration sensor.
At present, the application of sensor is extensive day by day, from being used for aspects such as military and exact instrument, is just changing the civilian stage over to.This makes vibration transducer obtain very big development, and the future that is widely used.In the prior art, little vibration sensor of technology such as widespread usage electromagnetic field mode and power sensing mode exists complex structure, makes trouble, problem such as cost height, thereby has limited further applying of it.
In view of the foregoing, the design provides a kind of little vibration sensor simple in structure.
Design proposal of the present utility model is achieved in that mainly to be made up of insulation shell, electrode, electric conductor and monostalbe trigger.Promptly on the inwall of insulation shell body cavity, be arranged to right electrode, connect an electrode order steady state trigger of paired electrode through mobilizable electric conductor.In paired telegraph circuit, impedance is arranged, connect through movable electric conductor and can not cause short circuit.Insulation shell be shaped as square or non-square.Be arranged to right electrode in the one side of insulation shell inwall or simultaneously.Electrode be shaped as rectangular parallelepiped or other shape.Electric conductor be shaped as spheroid or non-spheroid.Electrode and electric conductor are the metal material or the nonmetallic materials of high conductivity.
Little vibration sensor of the design, dependable performance, simple in structure, volume is little, and cost is lower.Be applicable to a plurality of fields such as machinery, instrument, household electrical appliance, easy to utilize.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a sectional structure chart of the present utility model.
With reference to Fig. 1, on the bottom surface of square organic glass housing 1 inner chamber, be fixed with the rectangular electrode 3,4 of two mutually insulateds, in organic glass housing 1 chamber, be equipped with a diameter greater than movable conducting sphere 2 clearance for insulation between the rectangular electrode 3,4 and can be in the chamber free.Rectangular electrode 4 order steady state triggers 5 are to carrying out shaping because conducting sphere 2 vibrates the electric signal that electrode 4 is produced. Rectangular electrode 3,4 and conducting sphere 2 are that the copper of high conductivity becomes.
