Description
Technical field
What the present invention relates to is a kind of monolithic quartz crystal filter fine setting circle and manufacture method, belongs to quartz crystal frequency and adjusts apparatus field.
Background technology
Quartz-crystal filter is widely used in electronic equipments such as communication, navigation, measurement, monolithic crystal filter wherein is because simple in structure, and volume is little, and price is low, it is very precipitous to add the upper frequency selectance, loss is low, and stability is good, the characteristic that stopband attenuation is high, become requisite elementary intermediate-frequency filter, in frequency was adjusted operation, the fine setting circle copper pipe that is used for carrying crystal very easily damaged, and useful life is only about 3 months.Copper pipe damages the cost height of back exchange copper pipe, does not then cause loose contact if do not exchange, and product percent of pass is low.Existing crystal filter fine setting circle copper pipe adopts installs snap ring in the top, guarantee that crystal pins contacts well with copper pipe.But the parallel socket on snap ring top speed when crystal pins is inserted is slower, and snap ring comes off after using a period of time easily, the easy scratch of the outer gold-plated film of crystal pins.The snap ring back crystal pins insertion meeting that comes off contacts badly with copper pipe, the product frequency scattered error of adjusting out is big, product fraction defective height, and efficient 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, is intended to improve the useful life that copper pipe is enclosed in fine setting, reduces the maintenance cost of fine setting circle, improves and finely tunes qualification rate.
Technical solution of the present invention: monolithic quartz crystal filter fine setting circle, its structure comprises the apron that copper pipe insertion mouth, fine setting circle entity, engaged test point, copper pipe groove mouth, insulation elastomeric material are made, wherein a side of copper pipe insertion mouth is fine setting circle entity, downward 5～10mm establishes a circle fine setting circle groove newly from the top at fine setting circle entity, apron is installed in this fine setting circle groove, and the degree of depth of fine setting circle groove is to the center that the copper pipe through hole is installed; Down one about 3/5ths concave indentation is cut in 5～10mm position from the copper pipe top, copper pipe groove mouth is on copper pipe top, crystal filter pin behind the insertion copper pipe is between copper pipe wall and the apron, in the circular fine setting circle bottom through-hole copper test contact is installed, this copper test contact and copper pipe bottom weld together.
Its manufacture method:
1) mouth is inserted at the copper pipe top and be processed into " V " font, in the concave indentation of cutting 3/5ths from downward 5～10mm position, copper pipe top;
2) downward 5～10mm establishes a circle groove newly from the top at the fine setting circle body, and the degree of depth is to the center that the copper pipe through hole is installed;
3) make apron with the insulation elastomeric material, be installed in the fine setting circle groove, utilize the elasticity of apron that all crystals pin is fully contacted with the copper pipe wall;
Thisly solve the method that crystal pins and copper pipe electrically contact on the whole, can improve crystal filter pin insertion speed and contact bad phenomenon with copper pipe with the minimizing pin, improve product percent of pass, prolong the useful life of copper pipe, and can not cause scratch to crystal pins coating.
Advantage of the present invention: the produced crystal filter fine setting of the technology of the present invention circle, needn't consider electrically contacting of each root copper pipe and crystal pins as existing scheme, but contact problems have between the two been solved on the whole, and speed is fast when product drops into, and has reduced that contact the bad product that causes with plumbers shed bad because of pin.Can extend to more than 3 years the useful life of copper pipe.Product percent of pass can improve more than 10%.
