Technical field
The utility model relates to piezoelectric seismometer fields, and in particular to a kind of piezoelectric seismometer machine core waterproof and anti-tampering knot Structure.
Background technique
Pressure point wave detector machine core output impedance is very big, needs circuit cooperation that could complete the conversion of impedance, pressure point wave detector Inner core be it is independent, the shell with machine core is insulation, and influence of the insulating resistance value to circuit is very big between line shell, if machine core Insulating resistance value reaches or approaches the impedance resistors value of circuit module, to detection becoming smaller due to getting damp, intake etc. between line shell Device overall performance index has very big influence;And piezoelectric seismometer machine core once leaves the dust proof workshop of production machine core, machine Insulating resistance value is easily affected by the external environment between core wire shell.
Summary of the invention
The utility model provides a kind of machine core with waterproof and anti-interference structure, especially a kind of piezoelectric seismometer machine Core waterproof and anti-interference structure.
The technical issues of the utility model is solved can be realized using following technical scheme:
A kind of piezoelectric seismometer machine core waterproof and anti-interference structure, at least incrustation and setting mass block inside the shell and Piezoelectric chip further includes signal wire, gland, sealing cover, sealing ring and sealing-plug, and upper end is provided with internal screw thread in the shell, institute It states housing top end and is provided with embedding slot, the sealing ring is embedded in embedding slot, and the gland is detachably connected on upper shell, and Gland is bonded with sealing ring top, and the gland top has protrusion, and the protrusion is outer to be provided with external screw thread, and the sealing cover passes through The external screw thread of protrusion is detachably connected, and circular seal slot is provided in the protrusion, and the sealing-plug is arranged in circular seal slot, And sealing cover top is bonded with sealing-plug top, the sealing cover and gland and sealing-plug are provided with wiring hole, the signal wire It is connect with piezoelectric chip, and signal wire passes through wiring hole.
The sealing-plug is pyramidal structure, and having a size of top end diameter 6.4*3.5mm, and the wiring hole of sealing-plug is two The wiring hole of 0.1mm.
Signal wire is a pair of 0.07m2Signal wire, a pair of signal wire is each passed through two wiring holes of sealing-plug.
Hollow cylinder is fixed on the sealing cover, and signal wire passes through hollow cylinder, the hollow cylinder is number steel.
The beneficial effects of the utility model are:
1, the core module of piezoelectric seismometer realizes hermetically sealed, after core module is sealed, it is desirable that the storage of core module Dis environment reduces, and can shift to an earlier date a certain amount of core module of production reserve, no longer be influenced by outside air humidity.
2, key technology of the invention is to be sealed between core shell and gland with sealing ring, and center signal line is close from taper Packing passes through, then with nut tightening, achievees the purpose that machine core is hermetically sealed.Protection point of the invention is that the machine core of piezoelectric seismometer is used The structure of sealing ring and conical gasket sealer in-core core.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
