[0002] The filter plays the role of filtering specific frequency signals in the circuit. When the current passes through the filter, a certain voltage drop will be generated. Performing a filter voltage drop test can evaluate the energy loss of the filter.
[0003] Current voltage drop testing methods typically require applying voltage to the filter input and connecting a voltage test device to the filter output to measure the output voltage and determine the filter's voltage drop.

During frequent testing, the cables can become tangled and knotted, impacting work efficiency and even causing damage due to improper placement. This increases production and maintenance costs, while cable organization is labor-intensive and time-consuming. To address this issue, we propose a filter voltage drop test fixture.

[0022] A baffle 13 that contacts the mounting plate 7 is fixedly installed on the outside of the connecting cable 9 . A movable block 14 that passes through the mounting tube 8 is fixedly installed on the outside of the connecting cable 9 . An elastic component connected to the movable block 14 is installed on one side of the mounting tube 8 .
[0023] Specifically, when in use, the connecting cable 9 is pulled toward a position close to the filter to facilitate electrical connection of the filter input and output ends to the adjustable power supply 10 and the voltage detection device 11, respectively. After the test is completed, the connecting cable 9 is pulled away under the pull of the elastic component to prevent the connecting cable 9 from being entangled and knotted.
[0024] Among them: the clamping assembly includes a sliding block 3, the sliding block 3 is slidably installed in the slide groove 2, a connecting rod 4 is installed on the outside of the sliding block 3, and one end of the connecting rod 4 is connected to a splint 5. Adjusting parts for driving the sliding block 3 to move are installed on both sides of the test bench 1. The adjusting parts are specifically electric push rods 6. The outer rod of the electric push rod 6 is assembled on one side of the test bench 1, and the inner rod of the electric push rod 6 moves through the test bench 1 to the slide groove 2. One end of the inner rod of the electric push rod 6 is fixed between the sliding block 3. Turning on the switch of the electric push rod 6 drives the sliding block 3 to move. The sliding block 3 drives the splint 5 to move through the connecting rod 4, and the two splints 5 clamp the outside of the filter.
[0025] Among them: the outer diameter of the movable block 14 is appropriately matched with the inner diameter of the mounting tube 8, the movable block 14 is slidably installed in the mounting tube 8, the elastic component includes a support rod 15, a connecting block 16 and an elastic rope 17, the support rod 15 is connected to one side of the mounting tube 8, the connecting block 16 is assembled at one end of the support rod 15, one end of the elastic rope 17 is connected to one side of the connecting block 16, and the other end of the elastic rope 17 is connected to one side of the movable block 14, and one end of the connecting cable 9 is installed with a terminal 12 for connecting to the filter.
