The existing filter is generally connected to the grounding wire by clamping a conductive sheet connected to the grounding wire directly between the nut and the grounding terminal to achieve the grounding effect of the power filter. However, when installing and removing the conductive sheet, the nut needs to be rotated and removed from the outside of the grounding terminal, and then the conductive sheet is placed on the outside of the grounding terminal, and then the nut is rotated to the outside of the grounding terminal to fix the conductive sheet. When removing the conductive sheet, the nut needs to be rotated and removed. This wastes a lot of time for the assembly and disassembly of the conductive sheet. In addition, the existing filter needs to be installed on the device housing, and the filter housing and the device housing will have multiple mounting holes reserved.

A clamping hole 202 is opened on one side of the outer end of the connecting block 201, and a stopper 203 is arranged on the outer side of the clamping column 2. When it is necessary to electrically connect the grounding wire 102 to the grounding block 101, the connecting block 201 can be placed on the outer side of the clamping column 2 through the clamping hole 202, and then the connecting block 201 is pressed against the stopper 203, so that one side of the connecting block 201 is tightly fitted with the grounding block 101, and one end of the grounding block 101 is connected to the grounding point of the filter body 1, so that the noise current of the filter body 1 can be guided to the ground through the grounding wire 102. Good grounding can reduce signal reflection and crosstalk, thereby improving signal integrity.

[0024] Among them, two fixing frames 3 are installed on both sides of the outer end of the filter body 1, and a slot 301 is opened on one side of the outer end of the fixing frame 3. The grounding block 101 and the clamping column 2 are both located inside the slot 301. When the connecting block 201 is installed to the outside of the clamping column 2, the pull plate 401, the movable rod 4 and the stop block 203 are driven by the handle 402 to move toward the movable plate 403 until the stop block 203 completely slides out from the outside of the clamping column 2. At this time, one end of the connecting block 201 is moved to the inside of the slot 301, and the connecting block is fixed through the clamping hole 202. 201 is placed on the outside of the column 2, and when the movable rod 4 moves, it will drive the movable plate 403 to move and compress the spring 404. After the connecting block 201 is placed on the outside of the column 2, the movable plate 403 is pushed by the elastic force of the spring 404, and the movable plate 403 drives the stop block 203 to move toward the grounding block 101 through the movable rod 4, until the stop block 203 moves to the outside of the column 2 and one side of it is in contact with the connecting block 201. At this time, the connecting block 201 can be clamped and fixed between the stop block 203 and the grounding block 101.

[0026] Among them, a movable groove 5 is opened inside the fixed frame 3, and two through holes 501 are opened on one side of the outer end of the fixed frame 3 and one side of the inner wall of the groove 301, and the four through holes 501 are respectively connected to the movable groove 5. The movable plate 403 and multiple springs 404 are all located inside the movable groove 5, and one end of the multiple springs 404 is in contact with one side of the inner wall of the movable groove 5. The through hole 501 is used to ensure that one end of the movable rod 4 can penetrate the fixed frame 3 and protrude from one side of the outer end of the fixed frame 3 to be connected with the pull plate 401, and one end of the spring 404 is in contact with the inner wall of the movable groove 5 to ensure that the spring 404 is compressed when the movable plate 403 moves.

[0027] Among them, both sides of the outer end of the filter body 1 are connected with mounting blocks 6, and one side of the outer ends of the two mounting blocks 6 is provided with three mounting grooves 601 in a long strip structure, and threaded columns 602 are arranged inside the six mounting grooves 601. The outer side of the threaded column 602 is threadedly connected with a nut 603. When the filter body 1 needs to be installed on the device housing, the filter body 1 is placed at the mounting hole reserved in the device housing, and the mounting hole is aligned with the mounting groove 601, and then the threaded column 602 is passed through the mounting groove 601 and turned into the mounting hole. When the threaded column 602 passes through the mounting hole without threads, the nut 603 can be rotated to the outside of the threaded column 602, so that the mounting block 6 and the filter body 1 can be fixed on the device housing, and the mounting groove 601 with a long strip structure can be aligned with multiple mounting holes at different positions, thereby ensuring the installation of the filter body 1.

[0028] Among them, an input terminal 7 is provided on one side of the outer end of the filter body 1, and an output terminal 701 is provided on the other side of the outer end of the filter body 1. When the filter body 1 is used, the input terminal 7 is used to receive the original signal from the external signal source, and the output terminal 701 is used to transmit the filtered signal to the subsequent circuit or load.

When the connecting block 201 is installed to the outside of the card column 2, the handle 402 drives the pull plate 401, the movable rod 4 and the stop block 203 to move in the direction of the movable plate 403 until the stop block 203 completely slides out from the outside of the card column 2. At this time, one end of the connecting block 201 is moved to the inside of the slot 301, and the connecting block 201 is placed on the outside of the card column 2 through the card hole 202. When the movable rod 4 moves, it will drive the movable plate 403 to move and compress the spring 404. After the connecting block 201 is placed on the outside of the card column 2, the elastic force of the spring 404 pushes the movable plate 403, and the movable plate 403 drives the stop block 203 to move in the direction of the grounding block 101 through the movable rod 4, until the stop block 203 moves to the outside of the card column 2 and one side of it is in contact with the connecting block 201. At this time, the connecting block 201 can be fixed between the stop block 203 and the grounding block 101.
