Present test for the power amplifier product, test again after need be with the screw of power amplifier product shell all fastening, when finding that in test process defective products or appearance test are unusual, need with check after the dismounting of power amplifier product shell or keep in repair after just can test again, need to repeat the aforesaid operations step as going wrong once more.In disassembly process repeatedly, screw can occur damages, bad phenomenon such as threaded hole stripped thread, the power amplifier product of power amplifier product shell broken, testing tool damage, this has just caused, and the fraction defective of product increases, cost increases, and big to the demand of hand labor power.
How by prior art is improved, make a kind of simple operation, and power amplifier product and testing tool are damaged little testing tool, this becomes present people's question of common concern, yet, also there not be the design of being correlated with now, do not see relevant report yet.
The utility model content
The purpose of this utility model is to overcome now power amplifier testing tool complicated operation when the power amplifier product is tested, power amplifier product and testing tool are fragile, and to the big problem of hand labor power demand, provide a kind of test after adopting the simulation screw fastening to the power amplifier product casing be used for the test fixture of power amplifier under simulation screw tightening state.
The purpose of this utility model is achieved through the following technical solutions:
Be used for the test fixture of power amplifier under simulation screw tightening state, comprise power amplifier test fixture body, power amplifier test fixture body comprises base and is arranged on base plate on the base, the upper surface of described base plate is provided with supporting plate and column, described column is provided with pressing plate, and this pressing plate is provided with the compression leg assembly.
Be provided with groups of springs between described base plate and the supporting plate.
Described supporting plate is provided with shielding cavity.
The quantity of described column is more than one.
Be connected with lever on the described pressing plate, and this lever is connected with handle.
Described lever is connected with handle by clamp.
Described pressing plate is connected with top board by coupling shaft, and described lever is connected on the top board.
Described compression leg assembly runs through pressing plate.
Described compression leg assembly mainly is made up of copper sheathing, compression leg and spring.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) pressing plate of the present utility model is provided with the compression leg assembly, when the power amplifier product is tested, the compression leg assembly constitutes the simulation screw and replaces the entity screw, when the appearance test is unusual, do not need the power amplifier product is dismantled, the right angle just can be tested by regulating the compression leg assembly, thereby has overcome bad phenomenon such as screw damage, the threaded hole stripped thread of power amplifier product shell, the power amplifier product that may cause in the unloading process are broken, testing tool damage, and has saved hand labor power.
(2) pressing plate of the present utility model is connected with top board by coupling shaft, and top board is connected with lever, and lever is connected with handle, and be provided with clamp between lever and the handle, directly move up and down with regard to the may command pressing plate by operating grip, therefore, the utility model simple operation.
