Reference numeral: 10, sensor core; 11, mass; 12, piezoelectric ceramics; 13, support; 20, radome; 30, insulating trip; 40, glass sintering two core connectors; 50, shell; 51, outer casing base; 60, inner space.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Be illustrated in figure 1 the utility model high dielectric voltage withstand vibration transducer embodiment, this vibration transducer sensor core 10, radome 20, insulating trip 30, shell 50 and connector, described radome 20 covers in sensor core 10 on insulating trip 30, by insulating trip 30, is fixed on outer casing base 51.Wherein, connector is glass sintering two core connectors 40, is located at above shell 50; Between glass sintering two core connectors 40, shell 50 and radome 20, form an inner space 60.These glass sintering two core connectors 40 adopt dielectric voltage withstand to make up to the glass sintering material of 4kV/AC, have improved the dielectric voltage withstand characteristic of heart yearn and shell, and its ground wire is connected with radome 20, and signal wire is connected with sensor core 10.
This sensor internal, forms the protection to sensor core 10 by radome 20 and insulating trip 30, and 60 li of the inner spaces forming at glass sintering two core connectors 40, shell 50 and radome 20 filling inert gas.Because the ionospheric structure of inert gas is stable, ionization activity is low, therefore strengthened the dielectric voltage withstand characteristic between radome 20 and shell 50, electric clearance and creepage distance of insulation have effectively been increased, significantly improved insulative dielectric performance, further guarantee to meet the high request of safety and Health monitoring system to vibration transducer, expanded the range of application of vibration transducer.
In this embodiment, sensor core 10 comprises sheathed successively support 13, piezoelectric ceramics 12 and mass 11, is located in radome 20, and compact conformation, volume are little, stable performance, safe.The ground wire of glass sintering two core connectors 40 is connected with radome 20, and signal wire is connected with the mass 11 of sensor core 10.Insulating trip 30 between sensor core 10 and outer casing base 51, has further improved the insulative dielectric performance of sensor.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but those skilled in the art should be understood that; within not departing from the spirit and scope of the present utility model that appended claims limits; the various variations of in the form and details the utility model being made, are protection domain of the present utility model.
