Description
Technical field
The utility model relates to microwave power device parameter measuring apparatus technical field.
Background technology
Carrying out microwave parameters test to Microwave Power Tubes is the requisite important step confirming the performance of power tube and assess.Microwave parameters test is carried out to Microwave Power Tubes, needs power tube to be fixed on special test fixture.In the common method of existing Microwave Power Tubes parameter testing, current domestic general way is, adopts screw to be directly fixed on test fixture by power tube, and direct screw fastening is installed for a small amount of and that reliability requirement is low method general by industry.
Utilize the method can realize for Microwave Power Tubes microwave parameters test test, the field such as production test, experimental test for Microwave Power Tubes have firm, simple and direct, contact good effect.But the method mounting screw holding time is long, easily scratches power tube surface, and directly scratch power tube base, leave scar, introduce test damage, repeatedly after installation testing, pipe base leaves indenture, damage power pipe, affect outward appearance and payment.Meanwhile, different power tubes is needed to back out screw and changes different power tubes, and each change power tube all will degree of tightness 2-4 screw repeatedly, virtually waste a large amount of time, this greatly reduces detection efficiency.
Utility model content
Technical problem to be solved in the utility model is the technical deficiency existed for above-mentioned proving installation, provides a kind of Microwave Power Tubes self-locking test fixture, reduces the test damage of Microwave Power Tubes, improves testing efficiency, shorten test period.
The technical solution adopted in the utility model is: provide a kind of Microwave Power Tubes self-locking test fixture, comprise aluminium alloy pedestal, the test circuit be fixed on aluminium alloy pedestal, also comprises briquetting, aluminium alloy pedestal has test trough; One end and the aluminium alloy pedestal of briquetting are hinged, and jointed shaft is socketed with the A reduction torsion spring of briquetting; The other end of briquetting is provided with fixing dead bolt; The position that aluminium alloy pedestal is corresponding with fixing dead bolt is connected with dead bolt clip, and pin sleeve is connected to the B reduction torsion spring of dead bolt clip; Position corresponding with test trough on the bottom surface of briquetting has at least two through holes; An insulated column is all slidably connected in each through hole; The lower end of insulated column extends to the outside of briquetting bottom surface; Back-moving spring is provided with between the upper end of insulated column and via bottoms.
Further optimization the technical program, on the bottom surface of the briquetting of Microwave Power Tubes self-locking test fixture, the position corresponding with test trough has four through holes.
Further optimization the technical program, the briquetting of Microwave Power Tubes self-locking test fixture is teflon material.
Further optimization the technical program, the lower surface of each insulated column of Microwave Power Tubes self-locking test fixture is all fixed with rubber blanket.
The beneficial effects of the utility model are: 1, easy to use, testing efficiency is high.Tested Microwave Power Tubes is directly put in test trough, then briquetting is covered, tested Microwave Power Tubes just compresses by insulated column, namely complete test to prepare, after having tested, open briquetting, take out tested Microwave Power Tubes, need not repeated disassembled and assembled screw, insulated column and Microwave Power Tubes Elastic Contact, can not cause test damage.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, Microwave Power Tubes self-locking test fixture, comprises aluminium alloy pedestal 1, the briquetting 2 of the test circuit be fixed on aluminium alloy pedestal 1, teflon material, aluminium alloy pedestal 1 has test trough 3; One end and the aluminium alloy pedestal 1 of briquetting 2 are hinged, and jointed shaft is socketed with the A reduction torsion spring 4 of briquetting 2; The other end of briquetting 2 is provided with fixing dead bolt 5; The position that aluminium alloy pedestal 1 is corresponding with fixing dead bolt 5 is connected with dead bolt clip 6, and pin sleeve is connected to the B reduction torsion spring 7 of dead bolt clip 6; On the bottom surface 8 of briquetting 2, the position corresponding with test trough 3 has four through holes 9; An insulated column 10 is all slidably connected in each through hole 9; The lower end of insulated column 10 extends to the outside of bottom surface 8; The lower surface of each insulated column 10 is all fixed with rubber blanket 12; Back-moving spring 11 is provided with between bottom the upper end of insulated column 10 and through hole 9.
Test circuit of the present utility model is identical with traditional test circuit, forms by gate bias circuit and drain bias circuit, unlike in Microwave Power Tubes 13 built-in test groove 3, and the connection of implementation and testing circuit in test trough 3.
During test Microwave Power Tubes 13, be placed in test trough 3, the pin of Microwave Power Tubes 13 is connected with corresponding test circuit, then overturn briquetting 2, fixing dead bolt 5 is snapped in dead bolt clip 6, finally adds electrical testing.
The effect of aluminium alloy pedestal 1 is not the carrier as Microwave Power Tubes 13 and its test circuit, radiating piece when also testing as Microwave Power Tubes 13.
When compressing Microwave Power Tubes 13, back-moving spring 11 bottom the upper end of insulated column 10 and through hole 9 is compressed, so insulated column 10 is Elastic Contact with the contact of compression Microwave Power Tubes 13, and the effect of rubber blanket 12 prevents insulated column 10 from damaging Microwave Power Tubes 13 further, allow that different size specification Microwave Power Tubes 13 is tested.
