Description

Technical Field

[0001] This utility model relates to the field of communication equipment, and in particular to an anti-interference communication transmission device. Background Technology

[0002] Communication equipment is an electronic device used to send, receive, convert, and process signals to achieve information transmission and exchange. They are widely used in various communication systems, such as wireless communication, fiber optic communication, satellite communication, and the Internet. The core function of communication equipment is to ensure effective signal transmission and minimize interference and signal distortion. The main role of communication equipment is to transmit information and data through different technologies and media, enabling people to engage in real-time communication, remote communication, and information sharing. They play a vital role in daily life and various industries, allowing people to quickly and conveniently transmit information between different locations, whether it be voice, text, video, or data. Common devices such as mobile phones, telephones, and fax machines support direct communication between people. In the workplace, communication equipment such as email, instant messaging software, and video conferencing systems help improve team collaboration and communication efficiency, avoiding information delays or misunderstandings.

[0003] However, existing technologies often encounter the following problems in use:

[0004] (1) Traditional external electromagnetic interference signals usually come from various electronic devices, communication base stations, power lines, radio frequencies, etc. When these electromagnetic waves propagate in the environment, they will enter the communication equipment with different frequencies, intensities, and modes. When these external interference signals meet the received signals of the equipment, signal overlap, distortion, or frequency aliasing will occur, which may lead to data loss, communication interruption, or equipment failure in severe cases. These interferences not only affect the quality of communication, but also cause delays and instabilities in information transmission, thereby affecting the overall performance and reliability of the equipment.

[0005] (2) Power supply noise and signal interference can also influence each other, creating a mutually reinforcing negative effect. In some devices, the power supply system may generate high-frequency noise or transient voltages, which are transmitted through power lines or grounding systems and enter the signal processing section of the device. At the same time, the signal path of the device may also be affected by electromagnetic interference emitted by other electronic components or modules. These power supply noises and signal interferences intertwine, exacerbating signal loss, reducing the system's anti-interference capability, thereby leading to a decline in device performance, and even instability and incorrect transmission of communication links, affecting the end-user experience. Utility Model Content

[0006] The main objective of this invention is to provide an anti-interference communication transmission device that solves at least one of the aforementioned problems to a certain extent.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] An anti-interference communication transmission device, comprising:

[0009] A shielding shell, comprising an outer layer, a middle layer, and an inner layer, wherein the outer layer is fitted over the inner side, and the middle layer is located between the inner layer and the outer layer;

[0010] Multiple interfaces are provided on one side of the shielding housing;

[0011] A data connector, which is plugged into any one of the plurality of interfaces;

[0012] A shielding layer, which is sleeved on the outer layer of the cable of the data connector;

[0013] A partition is disposed within the internal accommodating space of the shielding shell, dividing the shielding shell into a power supply area, a signal processing area, and a transmission area. The power supply area is connected to the plurality of interfaces, and the signal processing area and the transmission area are both located on one side of the power supply area.

[0014] Also includes:

[0015] A directional antenna, which is mounted on one side of the shielding housing, is a helical metal rod;

[0016] Heat dissipation fins are formed on the shielding shell and are located above the signal processing area;

[0017] A metal partition, the metal partition being located within the power supply area, the metal partition covering the battery in the power supply area;

[0018] An encoding processor is located within the signal processing area and below the heat sink fins;

[0019] A transmission board located within the transmission area.

[0020] The heat dissipation fins also include:

[0021] The heat dissipation holes are strip-shaped holes and are arranged side by side;

[0022] The shielding fins are annular and surround all the heat dissipation holes.

[0023] A metal strip, the two ends of which are connected to the annular fins of the shielding fin.

[0024] The transmission board is electrically connected to the directional antenna.

[0025] The outer layer is made of a metal alloy material.

[0026] The inner layer is an iron-nickel alloy.

[0027] The middle layer is a microwave absorbing material.

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] (1) To address the problem of external electromagnetic interference, this invention employs a three-layer shielding shell combined with a high-permeability iron-nickel alloy thin plate to ensure effective absorption and isolation of external electromagnetic interference signals. This shielding measure prevents external electromagnetic waves from affecting the device's signals, ensuring signal stability during communication. Furthermore, the signal processing module and other circuit components within the device are rationally laid out and optimized for electromagnetic compatibility, ensuring that the signal is not interfered with by external electromagnetic waves, thereby maintaining high-quality communication.

[0030] (2) To address the issue of mutual interference between power supply noise and signal interference, this design physically isolates the power supply area from the signal processing area, encapsulates the power supply area in a metal box, and sets up an independent power supply shield, effectively reducing the interference of power supply noise on the signal processing section. Through this design, power supply noise cannot be directly transmitted to the signal section, avoiding mutual interference between power supply and signal, thereby ensuring the stable performance of the equipment and the integrity of signal transmission.

[0037] 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.

[0038] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] like Figure 1-4 As shown, an anti-interference communication transmission device includes: a shielded shell 1, multiple interfaces 2, a data connector 3, a shielding layer 4, and partition plates 5. The shielded shell 1 includes an outer layer 101, a middle layer 102, and an inner layer 103. The outer layer 101 is fitted inside the shell, and the middle layer 102 is located between the inner layer 103 and the outer layer 101. The outer layer 101 is made of a metal alloy material, such as aluminum-magnesium alloy, which has good conductivity and strength. The shell is rectangular in shape, and seamless welding technology is used on all six sides of the shell to ensure the integrity of electromagnetic shielding. The inner layer 103 uses a thin iron-nickel alloy plate with high magnetic permeability. This thin plate is fixed to the outer shell 101 at a certain distance of 5-10 mm by a special fixing structure, such as evenly spaced elastic clips. The function of the inner layer 103 is to further absorb and isolate low-frequency magnetic field interference from the outside. A microwave absorbing material, such as a microwave absorbing sponge made of ferrite powder and polymer, is filled between the two shells. This absorbing material can effectively absorb electromagnetic interference waves that penetrate from the outer layer 101 and are reflected from the inner layer 103, converting them into heat energy and dissipating them.

[0040] In this embodiment, multiple interfaces 2 are located on one side of the shielding shell 1. A data connector 3 is plugged into any one of the interfaces 2. A shielding layer 4 is fitted over the outer cable layer 101 of the data connector 3. A partition 5 is disposed within the internal accommodating space of the shielding shell 1, dividing the shielding shell 1 into a power supply area 501, a signal processing area 502, and a transmission area 503. The power supply area 501 communicates with the multiple interfaces 2, and the signal processing area 502 and transmission area 503 are both located on one side of the power supply area 501. For various interfaces of the device, such as power interfaces and signal interfaces, the power supply area 501 is encapsulated in an independent metal box. The metal box is completely enclosed except for the power cable inlet. The circuit board layout inside the power supply area 501 adopts a multi-layer board structure, with power lines and ground lines of different layers interleaved to reduce electromagnetic interference generated by the power supply itself. An independent metal shielding cover is used. The shielding cover is well grounded to the outer shell 101 of the device via a grounding spring plate. The interface connection cable uses a dedicated cable with a metal braided shielding layer 4. The shielding layer 4 is grounded 360 degrees around the device interface to prevent interference waves from entering the device from the interface. The transmission area 503 is located on the other side of the device, and this area mainly contains the circuitry related to the transmitting and receiving antennas.

[0041] In the above embodiment, a filtering circuit is provided between the transmission area 503 and the signal processing area 502. The filtering circuit is installed in a separate metal box to prevent interference signals from the signal processing area 502 from entering the transmission area 503, and also to prevent interference signals from the transmission area 503 from entering the signal processing area 502 in the opposite direction.

[0042] In this invention, a directional antenna 6 is mounted on one side of the shielding housing 1. The directional antenna 6 is a spiral metal rod. Heat dissipation fins 7 are formed on the shielding housing 1 and are located above the signal processing area 502. A metal partition 8 is located within the power supply area 501, covering the battery in the power supply area 501. An encoding processor 9 is located within the signal processing area 502, below the heat dissipation fins 7. A transmission board 10 is located within the transmission area 503 and is electrically connected to the directional antenna 6. In the encoding processor 9, different functional circuit modules, such as the modulation module and the encoding module, are isolated by a metal shield, which is grounded. Signal transmission between modules is achieved through a ribbon cable with a shielding layer 4, both ends of which are grounded.

[0043] In this invention, the antenna uses a directional antenna structure 6, and the antenna element is a specially shaped metal rod, such as a spiral metal rod. This shape of the element enhances the antenna's directivity and reduces the reception of interference signals from non-communication directions. The outer layer 101 of the antenna is wrapped with a wave-transparent electromagnetic shielding material, which allows electromagnetic waves of the communication frequency to pass through but blocks interference waves of other frequencies. At the antenna's feed point, a small filter circuit is provided to further filter out any interference signals that may be mixed in.

[0044] To ensure a balance between heat dissipation and shielding effectiveness, the heat dissipation fins 7 include: strip-shaped heat dissipation holes 71 arranged side-by-side; annular shielding fins 72 surrounding all the heat dissipation holes 71; and metal strips 73 connected at both ends to the annular fins of the shielding fins 72. The shielding fins 72 are made of copper. The fins not only ensure good airflow for heat dissipation but also guarantee electromagnetic shielding effectiveness within the electromagnetic shielding frequency range, such as 100kHz-10GHz. Adjacent fins are connected at specific locations via metal jumpers to maintain the continuity of electromagnetic shielding.

[0045] It should be noted that when using the anti-interference communication transmission device designed in this utility model, check whether the shielding shell 1 is intact, and whether the outer layer 101, middle layer 102, and inner layer 103 are damaged, especially checking whether the seamless welds are firm to ensure the integrity of electromagnetic shielding. Check whether the multiple interfaces 2 are normal, including the internal structure of the interfaces and whether the shielding layer 4 around the interfaces is intact. Ensure that the cable connecting the device is a dedicated cable with a metal braided shielding layer 4, and that the cable is not damaged. As needed, insert the corresponding data connector 3 with the shielding layer 4 into the appropriate interface among the multiple interfaces 2 opened on one side of the shielding shell 1. Ensure that the shielding layer 4 is sleeved on the outer layer 101 of the cable of the data connector 3, and that the shielding layer 4 is grounded 360 degrees around the device interface. If power connection is involved, connect the power cord to the corresponding interface of the power supply area 501. The power supply area 501 is encapsulated in an independent metal box, and the rest is completely sealed except for the power cord inlet. Turn on the power. Due to the multi-layer board structure inside the power supply area 501, the power cords and ground wires of different layers are distributed alternately, which can reduce the electromagnetic interference generated by the power supply itself. After the signal enters the device through the interface, it is processed in the signal processing area 502.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
