The installing hole of existing test fixture is all evenly distributed, and thus needs additionally to design special test fixture.
Utility model content
Technical problem to be solved in the utility model is that the quartz providing a kind of antidetonation, waterproof and dustproof effective is scratched
Property accelerometer assembly.
The technical solution of the utility model is as follows: a kind of quartz flexible accelerometer assembly, including quartz flexible acceleration
Meter (1) and shell (3), in wherein quartz flexible accelerometer (1) and circuit board (2) are contained in described shell (3), quartz flexible adds
Velometer (1) electrically connects with circuit board (2)；Described shell (3) outer wall is provided with a triangle mounting flange (3a), this triangle
Each apex of shape mounting flange has the installing hole (3a ') of a up/down perforation, it is characterised in that: described quartz is scratched
Property accelerometer (1) be positioned at circuit board (2) lower section, be provided with pad between the bottom of this quartz flexible accelerometer and shell (3)
(5), and described circuit board (2) is connected to go between (6), and this lead-in wire stretches out after the installation via on described shell (3) sidewall；Institute
Having filled Silica hydrogel in stating shell (3), the opening of this shell upper end is closed by one piece of cover plate (7).
In said structure, pad (5) can adjust cross-couplings, it is ensured that quartz flexible accelerometer (1) is installed with shell (3)
Face perpendicularity requirement.Use Silica hydrogel can improve antidetonation, waterproof and dustproof effect, be so possible not only to protect quartz flexible to accelerate
Degree meter and circuit board, and ensure the installation accuracy of quartz flexible accelerometer.Further, lead-in wire (6) design is used not only to save
Switching circuit board, simplifies structure, reduces cost, and can avoid damaging lead-in wire, effectively overcomes tradition contact pin structure
The defect of circuit board connecting line and contact pin weld easy fracture.
As preferably, and three described installing holes (3a ') uniform along the circumference of shell (3), thus can use existing
Test fixture, thus improve performance of the present utility model.
In order to prevent scratching lead-in wire (6), described lead-in wire (6) being set with protection set (8), this protection set snaps in described
In installation via on shell (3) sidewall, then by gluing fixing.
As preferably, between described cover plate (7) and shell (3), use 3 circumference uniform distribution postweldings, then by gluing fixing.
Using above structure, be just avoided that the cover plate (7) of thin-walled deforms because welding is heated, 3 circumference uniform distributions weld also
Readily accessible and maintenance.
Beneficial effect: this utility model has the advantage that
1, use Silica hydrogel to fill shell inner cavity, thus improve antidetonation, waterproof and dustproof effect, be so possible not only to protection
Quartz flexible accelerometer and circuit board, and ensure the installation accuracy of quartz flexible accelerometer；
2, use lead design not only to eliminate switching circuit board, simplify structure, reduce cost, and can avoid
Damage lead-in wire, effectively overcome the circuit board connecting line of tradition contact pin structure and the defect of contact pin weld easy fracture.
3, three installing holes are uniform along the circumference of shell, thus can improve interchangeability, such that it is able to use existing survey
Trial work fills.
