Description
Technical field
The present invention relates to a kind of microwave filter, more particularly to a kind of test fixture for testing surface-mount type wave filter.
Background technology
With the development of radio-frequency technique, the transceiver channel of some conventional communication equipments needs surface-mount type wave filter increasingly
It is many, therefore, the requirement to surface-mount type filter frequencies index is increasingly harsh.
For surface-mount type filter device, if to realize that intact payment user uses, wave filter is just must assure that
The characterisitic parameter of setting can be met, therefore, need that filter device first is arranged on into bottom in surface-mount type wave filter production process
Primary screening debugging is first carried out on seat, the device debugged then could be screened and be done experiment checking, finally tested.And this
Plant way and there is Railway Project：First, whether the installment state for screening debugging is consistent, if installment state is inconsistent, is grounded shape
State is not good, and surveying parameter must change, and increased debugging difficulty.Second, after the completion of device experiment, state during test
It is different with screening adjustment and installation state, the disqualification rate of product can be increased.
It is well known that if surface-mount type filter device earthing effect is bad, installment state is inconsistent, and screening can be caused to debug
Inefficiency and test accuracy it is low be also unfavorable for batch production, on the one hand can increase the cost of product, the qualification rate of product
It is greatly reduced, therefore, it is possible to ensure that installment state is consistent, earthing effect good screening debugging, the fixture of test, for carrying
The scheduling and planning of surface-mount type filter device is risen, testing efficiency is significant, and does not meet the requirement also in the prior art
Fixture.
The content of the invention
It is it is an object of the invention to provide a kind of efficiency and reliability high, and simple structure, it is with low cost, be easily achieved
Test the test fixture of surface-mount type wave filter.
The purpose of the present invention is achieved through the following technical solutions：
The test fixture of test surface-mount type wave filter of the invention, including the testing base and top pressure that side is hinged
Block, is provided with hollow test trough, the test trough and tested surface-mount type filter device bottom shape in the testing base
Shape is consistent, and the test trench bottom sets the multiple ground connection of quantity and plays pin and be provided with input and output shell fragment, the top pressure at two ends
Block inner face is provided with raised line, the raised line when the top briquetting is fallen within shown testing base with the tight contract of the test trough
Close.
As seen from the above technical solution provided by the invention, test surface-mount type wave filter provided in an embodiment of the present invention
Test fixture, can screen in the surface-mount type filter device production process apply in debugging, test, can effectively improve survey
The precision of examination and the efficiency of debugging, improve the reliability of production speed and product, and simple structure, low cost
It is honest and clean, it is easy to accomplish.

Raised line.
Specific embodiment
With reference to the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Ground description, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based on this
Inventive embodiment, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, belongs to protection scope of the present invention.
The test fixture of test surface-mount type wave filter of the invention, its preferably specific embodiment is：
The testing base and top briquetting being hinged including side, hollow testing in being provided with the testing base
Groove, the test trough is consistent with tested surface-mount type filter device bottom shape, and it is multiple that the test trench bottom sets quantity
Ground connection plays pin and is provided with input and output shell fragment at two ends, and the top briquetting inner face is provided with raised line, and the raised line is on the top
Closely agree with the test trough when portion's briquetting is fallen within shown testing base.
The ground connection bullet pin is realized soft for tested surface-mount type filter device with input and output shell fragment with test fixture
Connection.
The raised line compresses tested surface-mount type filter device, makes tested surface-mount type filter device uniform force.
The test fixture of test surface-mount type wave filter of the invention, can screen in surface-mount type filter device production process
Applied in debugging, test, can effectively improve the precision of test and the efficiency of debugging, improve production speed and product
The reliability of product, and simple structure, it is with low cost, it is easy to accomplish.
Specific embodiment：
As shown in figure 1, including testing base, test trough, the test trough and table are provided with the middle part of the testing base
The bottom size shape of mounted filter device is consistent, and the test trough is used for device performance and tests and circuit debugging；The survey
Experimental tank bottom is in contact equipped with pin, the bullet pin is played with the bottom surface of the surface-mount type wave filter device；There is output in the test trough
