Abstract
A high-G piezoelectric acceleration transducer comprises a base, a piezoelectric device, a bracket and a cable; the piezoelectric device is connected with the column of the bracket via glue, the cable is adhered to the bracket via high-strength glue, the positive electrode and the negative electrode of the cable are correspondingly connected with the positive electrode and the negative electrode of the piezoelectric device respectively, then the bracket which is adhered with the piezoelectric device and the cable is adhered to the base via glue. The high-G piezoelectric acceleration transducer uses shear force generated when vibrating by gravity of the piezoelectric device for generating electric charges; and the high-G piezoelectric acceleration transducer uses the cable for transferring the generated electric charges outward to a signal conditioner, the high-G piezoelectric acceleration transducer changes installation way of the piezoelectric device from traditional base installation to upper bracket hanging installation, and increases impact resistance. The high-G piezoelectric acceleration transducer spreads an insulation layer on the place of the bracket which is fixed with the piezoelectric device for reaching requirement of insulating the transducer, does not use connectors in fact, throws wires directly, and protects the root of the cable, and guarantees that the cable is difficult to damage while being impacted largely.
Description
Technical field
The utility model belongs to electronic technology field, relates to acceleration transducer, relates in particular to a kind of high G value piezoelectric acceleration transducer.
Background technology
Domestic like product designs piezoelectric acceleration transducer owing to structural design often is employed in the method that adds mass on the piezoelectric device; Can cause total quality higher like this; Make the impact of product tolerance can't reach 100,000 acceleration of gravity; External product also exists and impacts cable root fracture when reaching 100,000 acceleration of gravity, perhaps problem such as sensor failure.In addition, like product often adopts the bottom to add the mode of collets at sensor insulating Design this part, and the mode that perhaps adds insulating screw realizes insulation, and technology is loaded down with trivial details, under the efficient.
Summary of the invention
The utility model purpose is to solve above problem, and a kind of low noise is provided, and cable is not fragile, special insulation mode, simple and reliable high G value piezoelectric acceleration transducer.
For reaching above-mentioned purpose, the utility model adopts following technical scheme:
High G value piezoelectric acceleration transducer comprises: pedestal, piezoelectric device, support, cable; Piezoelectric device is connected on the pillar of support with glue, with cable through the high strength glue bond on support, the both positive and negative polarity of cable respectively with the corresponding connection of both positive and negative polarity of piezoelectric device, the support that will glue piezoelectric device and cable again sticks with glue knot on pedestal.
Adopt technique scheme, the utility model utilizes the gravity of piezoelectric device self, and the shearing force that when vibration, produces produces electric charge.And the electric charge that produces with the cable handle reaches signal conditioner outward.The mounting means of piezoelectric device is installed by traditional pedestal and is changed the installation of upper bracket suspension type into, increases impact resistance value.On support, smear the requirement that insulation course reaches the sensor insulation with the fixing place of piezoelectric device.Impracticable connector, directly fishing line, and do protection at the cable root and handle, guarantee that cable is not fragile when receiving HI high impact.
Description of drawings
Below with accompanying drawing the utility model is specified:
Fig. 1 is the utility model decomposition texture synoptic diagram;
Fig. 2 is the utility model unitized construction synoptic diagram.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is detailed
Like the embodiment of the utility model of Fig. 1-shown in Figure 2, high G value piezoelectric acceleration transducer comprises: pedestal 1, piezoelectric device 2, support 3, cable 4; Piezoelectric device 2 is connected on the pillar of support 3 with glue; Cable 4 is passed through the high strength glue bond on support 3; The both positive and negative polarity of cable 4 respectively with the corresponding connection of both positive and negative polarity of piezoelectric device 2, the support that will glue piezoelectric device and cable again sticks with glue knot on pedestal 1.
The utility model utilizes the gravity of piezoelectric device self, and the shearing force that when vibration, produces produces electric charge.And the electric charge that produces with the cable handle reaches signal conditioner outward.The mounting means of piezoelectric device is installed by traditional pedestal and is changed the installation of upper bracket suspension type into, increases impact resistance value.On support, smear the requirement that insulation course reaches the sensor insulation with the fixing place of piezoelectric device.Impracticable connector, directly fishing line, and do protection at the cable root and handle, guarantee that cable is not fragile when receiving HI high impact.
