Description

Technical Field

[0001] This utility model relates to a high-performance power filter structure and belongs to the field of power filter technology. Background Technology

[0002] An EMI power filter acts as two low-pass filters: one attenuates common-mode interference, and the other attenuates differential-mode interference. An EMI power filter attenuates radio frequency energy within its stopband, allowing power frequency energy to pass through with little or no attenuation. EMI power filters are the preferred tool for electronic equipment design engineers to control conducted and radiated electromagnetic interference. However, during wiring and installation, unstable connections at the connection points are common; and the filter is prone to swaying during installation on the track. Utility Model Content

[0003] The purpose of this invention is to provide a high-performance power filter structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a high-performance power filter structure, including a rail, a power filter, wiring ports, tightening screws, cable management racks, rail mounting racks, and rail support racks. Wiring ports are installed on the left and right sides of the power filter. The wiring ports are threadedly connected to the tightening screws. The wiring port racks are inserted into the cable management racks. The rail mounting racks at the front and rear positions of the power filter are installed by positioning and connecting with the rail through the rail support racks.

[0005] Preferably, the track support frame consists of positioning bolts, support springs, irregular brackets, and horizontal support pads. The positioning bolts position and install the irregular brackets through the support springs, and the irregular brackets are horizontally welded and installed at the bottom.

[0006] Preferably, the cable management rack consists of plugs, fixing screws, a crossbar and a wiring limiting groove. Plugs are welded and installed at both ends of the crossbar, and fixing screws are screwed and tightened onto the side end faces of the plugs. The wiring limiting groove is welded and installed on the horizontal frame of the crossbar.

[0007] Preferably, a rubber pad is attached to the bottom of the horizontal support pad.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] The track support frame consists of positioning bolts, support springs, irregular brackets, and horizontal support pads. The support springs provide elastic support for the irregular brackets, while the horizontal support pads stably support the track base plate, ensuring stable installation without wobbling. The cable management frame consists of inserts, fixing screws, crossbars, and wiring limit grooves. The inserts of the cable management frame are inserted and mated with the edge of the wiring port and then fixed with fixing screws. After the wiring port is connected to the cable by tightening the screws, the cable is embedded in the inner diameter of the wiring limit groove, which can reduce the probability of the cable falling off due to irregular swinging and pulling.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] like Figures 1-4 As shown, a high-performance power filter structure includes a rail 1, a power filter 2, a wiring port 3, a tightening screw 4, a cable management rack 5, a rail mounting bracket 6, and a rail support bracket 7. The power filter 2 has wiring ports 3 installed on its left and right sides. The wiring ports 3 are threadedly connected to the tightening screw 4. The wiring port 3 frame is inserted into the cable management rack 5. The rail mounting bracket 6 at the front and rear positions of the power filter 2 is positioned and connected to the rail 1 through the rail support bracket 7.

[0017] The track support frame 7 consists of positioning bolts 8, support springs 9, irregular brackets 10, and horizontal support pads 11. The positioning bolts 8 position and install the irregular brackets 10 through the support springs 9. The bottom of the irregular brackets 10 is horizontally welded with the horizontal support pads 11. The support springs 9 provide elastic support for the irregular brackets 10. The horizontal support pads 11 stably support the bottom plate of the track 1, ensuring stable installation without shaking.

[0018] The cable management frame 5 consists of insert blocks 12, fixing screws 13, a cross frame 14, and a wiring limiting groove 15. Insert blocks 12 are welded and installed at both ends of the cross frame 14. Fixing screws 13 are tightened and installed on the side end face of the insert blocks 12. The wiring limiting groove 15 is welded and installed on the horizontal frame of the cross frame 14. After the insert blocks 12 are inserted and connected to the edge of the wiring port 3, they are fixed by fixing screws 13. After the wiring port 3 is connected to the cable by tightening screws 4, the cable is embedded in the inner diameter of the wiring limiting groove 15, which can reduce the probability of the cable falling off due to irregular swinging and pulling.

[0019] The bottom of the horizontal support plate 11 is fitted with a rubber pad, which has a certain buffering performance and a high coefficient of friction and strong stability.

[0020] Specific usage: A high-performance power filter structure. This device is designed for stable wiring and fixed installation of power filters on rails. The plug of the cable management frame is inserted and connected to the edge of the wiring port and then fixed with fixing screws. After the wiring port is connected to the cable by tightening screws, the cable is embedded in the inner diameter of the wiring limit groove, which can reduce the probability of the cable falling off due to irregular swinging. The support spring provides elastic support for the irregular bracket, and the horizontal support pad stably supports the bottom plate of the rail, ensuring stable installation without shaking.
