Description

TECHNICAL FIELD

[0001] The utility model belongs to filter technical field, concretely relates to a filter with communication access protection port. BACKGROUND

[0002] The filter is a common electrical component, which is used for effectively filtering a specific frequency point in a power line or a frequency outside the frequency point, obtaining a specific frequency power signal, or eliminating a specific frequency power signal. Generally, a protective box is arranged outside the filter, and a spacing groove is formed on the protective box, and a stabilizing mechanism is arranged in the spacing groove. The stabilizing mechanism can better protect the filter body, reduce damage to the filter body, and increase the stability of the filter body during movement. However, when the filter is used, it may be collided or pulled, and the line at the wiring port may be easily detached, which is inconvenient and affects use.

[0003] Therefore, a filter based on very high frequency adjustment with publication number "CN219960543U" is provided, which includes a filter body, the filter body is arranged on a mounting plate, a clamping mechanism is fixedly installed on the mounting plate, a plurality of wire pressing mechanisms are installed on the clamping mechanism, and a protective shell is installed on the mounting plate. The filter has good heat dissipation and protection effects, can tightly fix the line at the wiring port, and avoids the line at the wiring port from being detached, thereby affecting use.

[0004] However, for the filter based on very high frequency adjustment, although the wire pressing mechanism can tightly fix the line at the wiring port of the filter body, and avoid the line at the wiring port from being detached due to the filter body being pulled, the following obvious defects still exist during use: the wire pressing mechanism in the filter can tightly fix the signal, but the contact area of the pressing plate in the wire pressing mechanism is small, and the pressing plate tightly fixes the signal by using the elasticity of the spring. In addition, the elasticity of the spring gradually decreases when the spring tightly presses the pressing block for a long time, which causes the pressing block to tightly fix the inserted line, and the inserted line is loose and detached. TECHNICAL FIELD

[0005] The utility model aims at providing a filter with a communication access protection port to solve the problems in the background art.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a filter with a communication access protection port, which includes:

[0007] The filter body has a positioning pad at its bottom for positioning after installation. Side guards on both sides of the positioning pad protect the signal ports at both ends of the filter body from external signal lines. The filter body has a top guard that covers the end of the side guards. One side of the side guard has a port protection cavity that fits around the signal ports of the filter body and has a tapered structure at one end. A tapered positioning sleeve is inserted into the inner side of the outer end of the port protection cavity to tighten and position the connected signal line.

[0008] Preferably, one end of the filter body is provided with a signal input connection port, and the other end of the filter body is provided with a signal output connection port. The external surfaces of the signal input connection port and the signal output connection port are threaded locking surfaces, which can lock the external access line and the output line after they are inserted by thread.

[0009] Preferably, the positioning pad has a positioning groove at its end, and the bottom of the filter body is positioned and installed in the positioning groove. A silicone grease pad is provided at the bottom of the inner side of the positioning groove to position the filter body after positioning.

[0010] Preferably, the inner end of the port protection cavity is provided with a conical tightening and fixing cavity, and the outer side of the tightening and fixing cavity is uniformly provided with internal thread locking holes. The conical positioning sleeve is inserted into the tightening and fixing cavity to tighten and fix the connected signal terminal, and then locked by screws to achieve shrinking and pressing after the external signal line is connected.

[0011] Preferably, one side of the side guard plate is provided with a rubber pad, and the rubber pad is provided with a port protection cavity at the position corresponding to the signal input connection port and the signal output connection port, which can cover and protect the signal input port and the side of the filter, so that the access line is more secure and will not loosen after it is connected.

[0012] Preferably, a locking rod is provided through the bottom of one side of the side guard plate, and the locking rod is locked and fixed to one side of the positioning pad after the side guard plate is combined with the filter body and the positioning pad, so as to realize the installation of the side guard plate on the side of the filter.

[0013] Preferably, the top protective plate is fixed to the end of the filter body and has a rubber pad layer, and the two ends of the top protective plate cover the ends of the side protective plates, which can cover and protect the ends of the filter, and allow for ventilation and heat dissipation on the sides.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows: This filter with a communication access protection port, through the combination of a side guard plate, a port protection cavity, a conical positioning sleeve, and a conical tightening and fixing cavity, allows the signal line to pass through the port protection cavity and the conical tightening and fixing cavity and then be threadedly locked to the signal input connection port and the signal output connection port. At the same time, the port protection cavity in the rubber pad covers and protects the outside of the signal input connection port and the signal output connection port. The cylindrical positioning sleeve is inserted into the conical tightening and fixing cavity of the signal line. As the tightening and fixing cavity narrows, the conical positioning sleeve contracts and presses against the connection of the access line, thereby effectively tightening and fixing the connection between the access line and the signal input connection port and the signal output connection port. It also protects the access line port and the filter access port, so that it will not loosen or fall off during long-term use.

[0015] The filter body is positioned in the positioning groove by using a positioning pad, a positioning groove, a top protective plate on the filter body, and side protective plates that are locked on both sides. This ensures that the filter body remains in a stable position on the positioning pad. At the same time, the side protective plates are fixed to both ends of the positioning pad using rubber pads to press and position the filter body tightly against both ends. Furthermore, the top protective plate covers the ends of the side protective plates, thus effectively protecting the filter body and preventing it from shaking or loosening at the connection point under external force. This further ensures that the connection line is more secure and stable after connection, preventing the connection line from falling off. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a filter with a communication access protection port, comprising:

[0023] Filter body 1. Filters play a crucial role in signal processing. Their basic task is to allow or block signals within a specific frequency range to pass through, thereby altering the signal's spectral characteristics. They are widely used in communication, audio, imaging, medical, radar, and many other fields. Their main functions include noise reduction, signal separation, enhancement, smoothing, and bandwidth limiting, while their specific application scenarios vary depending on the application requirements. By rationally selecting and designing filters, the quality and efficiency of signal processing can be greatly improved, meeting the needs of different fields. The bottom of the filter body 1 is provided with a positioning pad 2 to position the filter body 1 after installation, which plays a supporting role in the installation and use of the filter body 1. The positioning pad 2 is provided with side guards 3 on both sides to protect the signal ports at both ends of the filter body 1 from external signal line connections. The side guards 3 can not only protect the input signal lines and connection ports, but also protect the sides of the filter body 1. The end of the filter body 1 is provided with a top guard 4 that covers the end of the side guards 3, allowing the filter body 1 to work in a relatively safe environment without external interference. One side of the side guard 3 is evenly provided with port protection cavities 5 that fit outside the signal ports of the filter body 1 and have a conical structure at one end, which plays a role in protecting the port of the body and the connection point of the input wire harness. The conical positioning sleeve 6 is inserted into the inner side of the outer end of the port protection cavity 5 to tighten and fix the input wire harness after it is connected, and facilitates the quick removal of the input signal wire harness later.

[0024] The filter body 1 has a signal input connection port 7 at one end. The signal source of the filter is input to the signal input port 7. The filter receives this input signal and processes it through its internal processing structure. The processing unit is responsible for processing the input signal according to the designed rules (such as frequency response, cutoff frequency, etc.). This part is usually implemented through circuits, algorithms, or mathematical models. The filter body 1 has a signal output connection port 8 at the other end. The output of the signal output port 8 is the result signal of the filter, that is, the signal after the filter processing. It can be an analog signal or a digital signal, depending on the type of filter. The signal input connection port 7 and the signal output connection port 8 have threaded locking surfaces on the outside. The positioning pad 2 has a positioning groove 9 at its end, and the bottom of the filter body 1 is positioned in the positioning groove 9, so that the filter body 1 is positioned in the positioning groove 9. The bottom of the inner side of the positioning groove 9 is provided with a silicone grease pad 10, which plays the role of absorbing and dissipating heat. The inner end of the port protection cavity 5 is provided with a conical tightening and fixing cavity 11, which can tighten and fix the access line. The outer side of the tightening and fixing cavity 11 is uniformly provided with internal threaded locking holes 12. The conical positioning sleeve 6 is inserted into the tightening and fixing cavity 11 to tighten and fix the access signal terminal and then lock it with screws.

[0025] The side guard plate 3 is provided with a rubber pad 13 on one side, which protects the end of the filter body 1. The rubber pad 13 is provided with a port protection cavity 14 at the position of the signal input connection port 7 and the signal output connection port 8, which realizes the outer protection of the access port. A locking rod 15 is provided through the bottom of one side of the side guard plate 3 to lock and fix the side guard plate 3. After the side guard plate 3 is combined with the filter body 1 and the positioning pad 2, the locking rod 15 is locked and fixed to one side of the positioning pad 2. The top guard plate 4 is fixed to the end of the filter body 1 and is provided with a rubber pad layer 16, which provides good protection for the filter body 1. The two ends of the top guard plate 4 cover the ends of the side guard plate 3.

[0026] Specifically, in use, first place the filter body 1 in the positioning groove 9 at the end of the positioning pad 2 to keep the filter body 1 in a fixed position during vibration. Then, assemble the side guard plates 3 at both ends of the filter body 1, allowing the rubber pads 13 to fit against the sides of both ends of the filter body 1. The signal input connection port 7 and the signal output connection port 8 are then enclosed in the port protection cavity 14 for protection. Next, use screws to fix the side guard plates 3 to the sides of both ends of the positioning pad 2. This allows the side guard plates 3 to protect the sides of the filter body 1 and position it on the positioning pad 2. Finally, thread the signal lines that need to be connected through the side guard plates. The tapered positioning sleeve 6 is used to connect the signal line to the signal input port 7 and signal output port 8 through the port protection cavity 5 and the tightening and fixing cavity 11. After thread locking, the tapered positioning sleeve 6 is inserted into the tightening and fixing cavity 11. As the tightening and fixing cavity 11 narrows, the tapered positioning sleeve 6 contracts and presses against the connection of the access line. This effectively tightens and fixes the connection between the access line and the signal input port 7 and signal output port 8, and also protects the access line port and the filter access port, so that it will not loosen or fall off during long-term use.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
