Description

Technical Field

[0001] This utility model relates to the field of filter technology, and more specifically to a filter with fixed lines to prevent incorrect insertion. Background Technology

[0002] A filter is a device or circuit that processes signals. It filters and selects input signals based on specific frequency characteristics, allowing certain frequency components to pass while suppressing or attenuating others. The basic principle of existing filters is to utilize the different impedance characteristics of circuit elements (such as resistors, capacitors, and inductors) to different frequency signals, thereby achieving frequency selection. For example, a capacitor presents low impedance to high-frequency signals, allowing them to pass easily, while presenting high impedance to low-frequency signals, hindering their passage. This forms the principle of a simple high-pass filter. In various electronic devices, filters are used to remove noise from the power supply, prevent mutual interference between signals, and improve signal quality and stability.

[0003] For example, the existing technology disclosure number CN214959475U is a mis-insertion prevention filter. This utility model can effectively prevent the input and output lines from twisting together, which would lead to a deterioration in the EMI characteristics of the whole machine, and it also has the function of preventing mis-insertion.

[0004] However, the existing technology described above still has the following problems in use: when connecting the filter, the wire ends are easily bent at the input and output terminals due to the softness of the wire material, affecting the service life of the wire. Therefore, this invention provides a filter with fixed wiring to prevent incorrect insertion. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a filter with fixed wiring to prevent incorrect insertion. A separator plate separates each pair of adjacent input terminals and each pair of adjacent output terminals, facilitating accurate insertion of wiring into the input and output terminals and preventing incorrect insertion from affecting the normal operation of the filter. Simultaneously, two arc-shaped clamps hold the wiring connected to the input and output terminals in place, thereby improving the stability of the wiring connections and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a filter body for preventing incorrect insertion, comprising a filter body, wherein multiple input terminals are fixedly provided on one side of the filter body, and multiple output terminals are fixedly provided on the other side of the filter body. Incorrect insertion mechanisms are fixedly provided on both sides of the filter body, each of which includes multiple partition plates. The partition plates are used to separate each pair of adjacent input terminals or each pair of adjacent output terminals. Two vertically symmetrically distributed grooves are provided on the outer walls of both sides of the partition plates. Two vertically symmetrically distributed arc-shaped clamps are provided on the outer walls of each input terminal and each output terminal. The arc-shaped clamps on the upper and lower sides are respectively fixed on two sliders, and the two sliders are slidably disposed within the grooves on the upper and lower sides.

[0007] In a preferred embodiment, the upper arc-shaped clamps are fixed to one of the upper sliders, and the lower arc-shaped clamps are fixed to another lower slider. The upper slider is slidably disposed in the upper groove, and the lower slider is slidably disposed in the lower groove.

[0008] In a preferred embodiment, three input terminals are fixedly provided on one side of the filter body, and three output terminals are fixedly provided on the other side of the filter body. Each anti-misinsertion mechanism includes two partition plates.

[0009] In a preferred embodiment, each slide groove is provided with a return spring. One end of the return spring is connected to the inside of the slide groove, and the other end of the return spring is connected to the slider. The slider can slide in the slide groove and squeeze the return spring. The elastic force of the return spring pushes the slider and the arc-shaped clamp to always be in contact with the circuit, thereby improving the stability of the circuit.

[0010] In a preferred embodiment, connecting plates are fixedly provided at the top and bottom of the two partition plates, and connecting grooves adapted to the connecting plates are machined on both sides of the filter body. The connecting plates are detachably connected and fixed to the connecting grooves, and the workers can remove the connecting plates from the filter body for quick replacement of the partition plates.

[0011] In a preferred embodiment, a limiting plate is fixedly provided on the outer wall of each slider, and a pin is fixedly provided on the limiting plate. Each partition plate has a socket adapted to the pin on its outer wall. The pin and the socket are detachably connected. When the operator is connecting the line, the pin and the socket are fixed to keep the arc-shaped clamp away from the line and prevent the arc-shaped clamp from affecting the installation of the line.

[0012] In a preferred embodiment, a rubber pad is fixedly bonded to the inner wall of each arc-shaped clamp. The outer surface of the rubber pad is processed with anti-slip texture. The rubber pad is made of soft material, which can play a buffering role between the arc-shaped clamp and the circuit, preventing the arc-shaped clamp from damaging the circuit. In addition, the anti-slip texture design can improve the stability between the rubber pad and the circuit.

[0013] In a preferred embodiment, the filter body is fixedly provided with fixing plates on both the front and rear sides, and fixing holes are opened on the top of both fixing plates. In actual use, the staff can use bolts to pass through the fixing holes to securely install the filter body for use.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] This invention uses multiple partition plates to separate each pair of adjacent input terminals and each pair of adjacent output terminals, making it easier for staff to accurately insert the wires into the input and output terminals and avoiding incorrect insertion that could affect the normal use of the filter body. At the same time, two arc-shaped clamps are used to hold the wires connected to the input and output terminals, thereby improving the stability of the wire connection and preventing the wires from bending and being damaged.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Refer to the instruction manual appendix Figures 1-6 This utility model provides a filter with fixed wiring to prevent incorrect insertion, including a filter body 1. Multiple input terminals 2 are fixedly mounted on one side of the filter body 1, and multiple output terminals 3 are fixedly mounted on the other side of the filter body 1. Anti-insertion mechanisms 4 are fixedly mounted on both sides of the filter body 1. Each anti-insertion mechanism 4 includes multiple partition plates 41, which are used to separate each pair of adjacent input terminals 2 or each pair of adjacent output terminals 3. Two vertically symmetrically distributed grooves 42 are formed on the outer walls of both sides of the partition plates 41. The outer walls of each input terminal 2 and... Each output terminal 3 has two symmetrically distributed arc-shaped clamps 43 on its outer wall. The arc-shaped clamps 43 on the upper and lower sides are respectively fixed on two sliders 44. That is, each arc-shaped clamp 43 on the upper side is fixed on one of the upper sliders 44, and each arc-shaped clamp 43 on the lower side is fixed on the other lower slider 44. The two sliders 44 are respectively slidably disposed in the upper and lower sliding grooves 42. That is, the upper slider 44 is slidably disposed in the upper sliding groove 42, and the lower slider 44 is slidably disposed in the lower sliding groove 42.

[0026] Specifically, in this embodiment, three input terminals 2 are fixedly provided on one side of the filter body 1, and three output terminals 3 are fixedly provided on the other side of the filter body 1. Each anti-misinsertion mechanism 4 includes two partition plates 41, but is not limited thereto.

[0027] Furthermore, a return spring 45 is provided inside each slide groove 42. One end of the return spring 45 is connected to the inside of the slide groove 42, and the other end is connected to the slider 44. The slider 44 can slide inside the slide groove 42 and compress the return spring 45. Connecting plates 5 are fixedly provided at the top and bottom of the two partition plates 41. Connecting grooves 6 adapted to the connecting plates 5 are machined on both sides of the filter body 1. The connecting plates 5 are detachably connected and fixed to the connecting grooves 6 by bolts or plugs. The operator can remove the connecting plates 5 from the connecting grooves 6 of the filter body 1 for quick replacement of the partition plates 41.

[0028] Each slider 44 has a fixed limiting plate 7 on its outer wall, and a pin 8 is provided on the limiting plate 7. Each partition plate 41 has a socket 9 that matches the pin 8 on its outer wall. The pin 8 and the socket 9 are detachably connected. When the operator is connecting the line, the pin 8 and the socket 9 are fixed to keep the arc-shaped clamp 43 away from the line and prevent the arc-shaped clamp 43 from affecting the installation of the line.

[0029] In actual use, the operator first moves the slider 44 and the arc-shaped clamp 43 to a location away from the input terminal 2 and the output terminal 3. The slider 44 slides within the groove 42, compressing the return spring 45, and is then fixed to the socket 9 using the pin 8. Figure 4 As shown; then, the connecting plate 5 is aligned with the connecting slot 6 and inserted. The two partition plates 41 on the left and right sides of the filter body 1 separate the three input terminals 2 and the three output terminals 3, so as to facilitate the staff to accurately insert the wires into the input terminals 2 and output terminals 3, and avoid incorrect insertion affecting the normal use of the filter body 1. After the wires are connected, the staff pulls the pin 8 on the limiting plate 7 out of the socket 9. The two sliders 44 move closer to each other under the elastic force of their respective return springs 45, which drives the two arc-shaped clamps 43 to move closer to each other and contact the wires, as shown. Figure 5 As shown, the two arc-shaped clamps 43 distributed vertically clamp the lines connected to the input terminal 2 and the output terminal 3, thereby improving the stability of the connection at the end of the line and preventing the line from bending and being damaged. In addition, the connecting plate 5 can provide a certain degree of protection above and below the input terminal 2 and the output terminal 3, thereby improving the service life of the input terminal 2, the output terminal 3 and the line.

[0030] In this embodiment, a rubber pad 10 is fixedly bonded to the inner wall of each arc-shaped clamp 43. The outer surface of the rubber pad 10 is processed with anti-slip texture. The rubber pad 10 is made of soft material and can play a buffering role between the arc-shaped clamp 43 and the circuit, so as to prevent the arc-shaped clamp 43 from damaging the circuit.

[0031] The filter body 1 is fixedly provided with fixing plates 11 on both the front and rear sides. The top of each fixing plate 11 is provided with fixing holes 12. In actual use, the staff can use bolts to pass through the fixing holes 12 to securely install the filter body 1 for use.
