Description
Technical field
The present invention relates to a kind of monolithic quartz crystal filter fine setting circle and manufacture method, belong to quartz crystal frequency and adjust apparatus field.
Background technology
Quartz-crystal filter is widely used in the electronic equipments such as communication, navigation, measurement, monolithic crystal filter therein is due to simple in construction, and volume is little, and price is low, add upper frequency selectance very precipitous, loss is low, and stability is good, the characteristic that stopband attenuation is high, become requisite primary intermediate-frequency filter, adjusting in operation in frequency, the fine setting circle copper pipe being used for carrying crystal very easily damages, only about 3 months service life. Copper pipe exchanges copper pipe cost after damaging is high, if not exchanging, causes loose contact, and conforming product rate is low. Existing crystal filter fine setting circle copper pipe adopts installs snap ring in top, it is ensured that crystal pins contacts well with copper pipe. But it is relatively slow that the parallel spigots on snap ring top inserts hourly velocity in crystal pins, and snap ring easily comes off after using a period of time, the easy scratch of the gold-plated film of crystal pins outer layer. After clamping ring falling, crystal pins insertion can contact bad with copper pipe, and the product frequency scattered error being adjusted out is big, and product fraction defective is high, and efficiency is low, as shown in Figure 2.
Summary of the invention
What the present invention proposed is a kind of monolithic quartz crystal filter fine setting circle and manufacture method, it is intended to improves the service life of fine setting circle copper pipe, reduces the maintenance cost of fine setting circle, improves fine setting qualification rate.
The technical solution of the present invention: monolithic quartz crystal filter fine setting circle, the apron that its structure includes copper pipe insert port, entity is enclosed in fine setting, engaged test point, copper pipe groove port, insulating elastic material are made, wherein the side of copper pipe insert port is fine setting circle entity, a circle fine setting circle groove is established newly from top down 5～10mm at fine setting circle entity, apron is arranged in this fine setting circle groove, and the degree of depth of fine setting circle groove is to the center installing copper pipe through hole;From copper pipe top, down the concave indentation of about 3/5ths is cut in 5～10mm position, copper pipe groove port is on copper pipe top, insert the crystal filter pin after copper pipe and be between copper pipe wall and apron, installing copper test contact in circular fine setting circle bottom through-hole, this copper test contact is together with copper pipe bottom welding.
Its manufacture method:
1) copper pipe top insert port is processed into " V " font, in the concave indentation cutting 3/5ths from copper pipe top down 5～10mm position;
2) establishing a circle groove at fine setting circle body newly from top down 5～10mm, the degree of depth is to the center installing copper pipe through hole;
3) make apron with insulating elastic material, be arranged in fine setting circle groove, utilize the elasticity of apron to make all crystal pins and copper pipe wall be fully contacted;
This method solving crystal pins and copper pipe electrical contact on the whole, crystal filter pin insertion speed can be improved and contact bad phenomenon with copper pipe with reducing pin, improve conforming product rate, extend the service life of copper pipe, and crystal pins coating will not be caused scratch.
Advantages of the present invention: the produced crystal filter fine setting circle of the technology of the present invention, the electrical contact of each copper pipe and crystal pins need not be considered as existing scheme, but solve contact problems between the two on the whole, and it is fast to put into hourly velocity at product, decrease because pin contacts bad with plumbers shed that cause product is bad. The service life of copper pipe can extend to more than 3 years. Conforming product rate can improve more than 10%.
