[0002] With the rapid development of 5G communications, smart grids and industrial Internet, data optical terminals, as core equipment for converting optical signals into electrical signals, are widely used in strong electromagnetic interference environments such as high-voltage substations, rail transit, and field communication base stations.

[0003] Traditional optical transceivers mostly use simple aluminum alloy casings, and internal heat dissipation mainly relies on small fans. Therefore, there are the following shortcomings:

[0004] First, a single-layer aluminum alloy shell cannot effectively shield low-frequency and high-frequency electromagnetic interference, which can easily cause signal distortion or interruption;

[0005] Second, there's a conflict between heat dissipation and sealing. Ventilation holes are necessary to control heat dissipation. However, these holes allow dust and moisture to enter, affecting heat dissipation and causing corrosion to the circuit boards. Furthermore, these holes further weaken the electromagnetic shielding effect of the single-layer aluminum alloy housing.

[0006] Third, the motherboard is mostly fixed with screws or disposable clips, which require tools for disassembly and assembly and are prone to damage to the shell; when external cables are connected, a chaotic layout can easily cause crosstalk, further reducing signal stability.

The sealed heat dissipation unit is used to balance the heat dissipation and sealing requirements. The heat spreader, heat pipe, heat dissipation base and heat conduction chamber work together to quickly extract and dissipate the heat of the components. At the same time, the entire device remains sealed, blocking the invasion of dust and moisture and preventing circuit corrosion. It has excellent heat dissipation and sealing performance.

[0054] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0055] The present invention provides an anti-interference data optical terminal and its use method, addressing the problems of traditional optical terminals in complex electromagnetic environments. The single-layer housing structure of the optical terminal is difficult to block strong electromagnetic interference, which can easily cause signal errors and packet loss. Furthermore, the optical terminal has poor heat dissipation and often uses fans for heat dissipation, which can easily overheat and damage components during high-temperature operation, and the vents reduce the electromagnetic shielding effect. Furthermore, the mainboard is cumbersome to fix and time-consuming to maintain, affecting the normal use of the equipment.

[0056] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0057] Embodiment 1: The embodiment of the present invention discloses a data optical terminal with anti-interference function. Figure 1 To the attached Figure 10 As shown, it includes an optical terminal housing 1, an interface panel 2, a snap-on base 3, a mainboard 4, a sealed heat dissipation unit 5, and a Faraday cage 7;

[0058] The optical terminal housing 1 is used to support the entire device. The optical terminal housing 1 adopts an inner and outer double-layer metal shell, and the middle is filled with absorbing material. The absorbing material adopts ferrite or conductive foam. The optical terminal housing 1 itself has a shell shielding effect. After the design of the inner and outer double-layer metal shell and the middle absorbing material, a more complex shielding cavity is formed. The outer metal shell reflects high-frequency electromagnetic waves, and the inner shell absorbs low-frequency residual interference. The absorbing material reduces the resonance effect of electromagnetic waves in the shell and avoids secondary radiation. Therefore, the equipment performs better in extremely strong interference fields. Combined with the design of the outermost Faraday cage 7, not only a multi-level anti-electromagnetic interference structure is formed, but also the grounding of the Faraday cage 7 prevents the entire optical terminal housing 1 from leakage and external electric shock. The Faraday cage 7 also protects the optical terminal housing 1 from damage, greatly improving the anti-interference ability and extending the service life of the optical terminal equipment.

[0059] The interface panel 2 is fixedly connected to the front of the optical terminal housing 1 and is used to connect to external devices to transmit data;

[0060] The clamping base 3 is provided at the bottom of the optical terminal housing 1 and is used for mounting the mainboard 4;

[0061] The mainboard 4 is fixedly connected to the card base 3. The mainboard 4 is provided with an optical terminal electronic component 41 and a terminal block 42. The optical terminal electronic component 41 is responsible for the core data processing function. A flat cable 421 is connected between the terminal block 42 and the interface panel 2; the terminal block 42 is connected to the interface panel 2 through the flat cable 421, forming a complete signal transmission link.

[0062] The sealed heat dissipation unit 5 is provided on the optical terminal housing 1 and is used to dissipate heat from the optical terminal electronic components 41. The sealed heat dissipation unit 5 includes:

[0063] A heat spreader 51 is fixedly connected to the main board 4 and contacts the optical terminal electronic components 41;

[0064] The heat dissipation base 52 is provided on the top of the optical terminal housing 1;

[0065] Several groups of heat pipes 53 are fixedly connected to the heat dissipation base 52;

[0066] The heat transfer chamber 54 is provided on the heat pipe 53 and is attached to the heat spreader 51;

[0067] The heat sink 51 of the sealed heat dissipation unit 5 is in close contact with the optical terminal electronic component 41 to collect heat, which is then transferred to the heat dissipation base 52 via the heat pipe 53. The heat transfer medium is provided inside the heat conduction chamber 54 and the heat pipe 53. After absorbing the heat, the heat is circulated, thereby enhancing the heat conduction efficiency and achieving efficient heat dissipation of the optical terminal electronic component 41.

[0068] The Faraday cage 7 is arranged outside the optical terminal housing 1, and uses the electromagnetic shielding principle to block external electromagnetic interference and ensure stable signal transmission inside the device.

[0069] A first mounting base 11 is provided at the bottom of the optical terminal housing 1. The snap-on base 3 is movably snap-fitted within the first mounting base 11. A locking unit 6 is provided on the first mounting base 11 for limiting the position of the snap-on base 3. The mechanical snap-on connection and the locking structure of the locking unit 6 facilitate installation and removal of the snap-on base 3, and facilitate maintenance or replacement of the mainboard 4. Maintenance operations are simplified, and the snap-on base 3 can be quickly installed and removed, reducing the time and difficulty of equipment maintenance.

[0070] A locking hole 31 is provided on the side of the clamping base 3, and the locking unit 6 includes:

[0071] The guide rail frame 61 is fixedly connected to the first mounting base 11;

[0072] The adjusting block 62 is movably connected to the guide rail frame 61;

[0073] The locking rod 63 is fixedly connected to the adjusting block 62 and movably inserted into the locking hole 31 .

[0074] The movement of the adjusting block 62 on the guide rail frame 61 drives the locking rod 63 to move, thereby realizing flexible locking and loosening of the clamping base 3 .

[0075] A reinforcement tube 32 is fixedly connected to the interior of the clamping base 3, corresponding to the position of the locking hole 31. A screw 64 is threadedly connected to the guide rail frame 61 and is rotatably connected to the adjustment block 62. The reinforcement tube 32 prevents deformation or damage to the clamping base 3 during locking. The rotation of the screw 64 drives the adjustment block 62 along the guide rail frame 61, facilitating adjustment of the adjustment block 62 and the locking rod 63. This ensures that the clamping base 3 and the mainboard 4 are easily disassembled and maintained, and maintains a stable position when the clamping base 3 and the mainboard 4 are fixed.

[0076] A mounting bracket 13 is fixedly attached to the bottom of the optical transceiver housing 1 and is fixedly connected to the Faraday cage 7. This bracket provides stable support and a secure anchor for the Faraday cage 7, facilitating the installation and securement of the entire optical transceiver. This ensures the stability of the Faraday cage 7, thereby ensuring its shielding effectiveness and providing a more secure installation that adapts to various installation environments.

[0077] The mounting bracket 13 is made of insulating material. The Faraday cage 7 includes a left metal frame 71 and a right metal frame 72. The left metal frame 71 is provided with a clamping column 711, and the right metal frame 72 is provided with a sleeve 721. The sleeve 721 is clamped with the clamping column 711. Both the left metal frame 71 and the right metal frame 72 are provided with a cable reinforcement rod 73.

[0078] The mounting bracket 13 is made of insulating material to avoid electrical coupling interference with the Faraday cage 7. The left metal frame 71 and the right metal frame 72 are connected in a snap-fit ​​manner to achieve quick assembly and disassembly of the Faraday cage 7, making the installation and maintenance of the Faraday cage 7 convenient. At the same time, the cable reinforcement rod 73 and the cable tie cooperate to facilitate cable positioning, prevent the cable from loosening, ensure stable cable connection, and further improve the anti-interference ability of the equipment.

[0079] The device utilizes the design of an optical terminal housing 1, an interface panel 2, a snap-on base 3, a mainboard 4, a sealed heat dissipation unit 5, and a Faraday cage 7, so that the entire mainboard 4 and the optical terminal electronic components 41 are placed in a closed environment, thereby preventing the intrusion of dust and foreign matter caused by the heat dissipation channel, and also avoiding signal interference caused by the entry of electromagnetic waves. At the same time, in conjunction with the design of the optical terminal housing 1 and the Faraday cage 7, a multi-level anti-interference capability is formed, ensuring the stability of the entire machine equipment and meeting usage requirements.

[0080] Embodiment 2: The embodiment of the present invention discloses a data optical terminal with anti-interference function. Figure 1 To the attached Figure 10 As shown, it includes an optical terminal housing 1, an interface panel 2, a snap-on base 3, a mainboard 4, a sealed heat dissipation unit 5, and a Faraday cage 7;

[0081] The optical terminal housing 1 is used to support the entire device;

[0082] The interface panel 2 is fixedly connected to the front of the optical terminal housing 1;

[0083] The clamping base 3 is arranged at the bottom of the optical terminal housing 1;

[0084] The mainboard 4 is fixedly connected to the card base 3. The mainboard 4 is provided with optical terminal electronic components 41 and a wiring seat 42. A flat cable 421 is connected between the wiring seat 42 and the interface panel 2.

[0085] The sealed heat dissipation unit 5 is provided on the optical terminal housing 1 and is used to dissipate heat from the optical terminal electronic components 41. The sealed heat dissipation unit 5 includes:

[0086] A heat spreader 51 is fixedly connected to the main board 4 and contacts the optical terminal electronic components 41;

[0087] The heat dissipation base 52 is provided on the top of the optical terminal housing 1;

[0089] The heat transfer chamber 54 is provided on the heat pipe 53 and is attached to the heat spreader 51;

[0090] The Faraday cage 7 is arranged outside the optical terminal housing 1 .

[0091] A second mounting base 12 is fixedly connected to the top of the optical terminal housing 1, and the heat sink base 52 is movably snapped into place within the second mounting base 12. The second mounting base 12 is used to mount the heat sink base 52. Bolts are used to secure the second mounting base 12 and the heat sink base 52 together. This facilitates assembly, disassembly, and maintenance of the heat sink base 52, ensuring stable heat dissipation. This also helps the heat sink base 52 dissipate heat generated by the device's operation and maintain the normal operating temperature of internal components.

[0092] The heat sink 52 has a cooling chamber 523 within it. A top cover 521 is located on top of the heat sink 52, which is equipped with several sets of heat fins 522. A cooling medium is located within the cooling chamber 523, and the heat pipes 53 are positioned within the cooling medium. The heat fins 522 on the top cover 521 increase the heat dissipation area. After the vapor chamber 51 collects heat, the heat pipes 53 transfer the heat to the cooling medium, where it is then dissipated by the heat fins 522.

[0093] The heat pipe 53 has efficient heat conduction and the cooling medium has heat absorption characteristics, which can quickly transfer and dissipate heat, achieve good heat dissipation effect, ensure that electronic components work at an appropriate temperature, extend service life, and improve working stability.

[0094] The bottom of the heat spreader 51 is provided with a plurality of heat conducting blocks 511, which are respectively attached to the optical terminal electronic components 41. The heat conducting blocks 511 increase the contact area and improve the heat collection efficiency.

[0095] A second aspect of the present invention provides a method for using a data optical terminal with an anti-interference function, the method comprising the following steps: Step S1: fixing the optical terminal housing 1 in an equipment cabinet via a mounting bracket 13, ensuring that the ground wire of the Faraday cage 7 is connected to the ground;

[0096] Step S2: Connect the fiber optic patch cord to the optical port of the interface panel 2, connect the data cable to the electrical port, and secure them with a cable tie and a cable reinforcement rod 73;

[0097] Step S3: When equipment maintenance is required, the adjusting block 62 is driven by rotating the screw 64 to disengage the locking rod 63 from the locking hole 31 , and the clamping base 3 is pulled out to perform maintenance on the mainboard 4 ;

[0098] Step S4: After maintenance, push back the clamping base 3 and reversely rotate the screw rod 64 to lock the main board 4;

[0099] Step S5: When the optical terminal is in operation, the heat of the electronic components 41 of the optical terminal is transferred to the heat spreader 51 via the heat conducting block 511;

[0100] Step S6: The heat from the vapor chamber 51 is introduced into the heat pipe 53 through the heat transfer chamber 54 and circulated by the cooling medium in the cooling chamber 523 to dissipate the heat.

[0101] Step S7: The Faraday cage 7 and the optical terminal housing 1 form a double-layer shielding structure to continuously shield external electromagnetic interference and ensure signal transmission stability.

[0102] In summary, the data optical terminal with anti-interference function uses a double-layer shielding system formed by the Faraday cage 7 and the optical terminal housing 1, and cooperates with the double-layer metal and absorbing material of the optical terminal housing 1 to form a multi-level electromagnetic shielding mechanism, which effectively resists high and low frequency electromagnetic interference and ensures stable signal transmission. The sealed heat dissipation unit 5 is used to balance the heat dissipation and sealing requirements. The heat sink 51, heat pipe 53, heat dissipation base 52 and heat conduction chamber 54 work together to quickly extract and dissipate the heat of the components. At the same time, the entire equipment remains sealed to block the invasion of dust and moisture and prevent circuit corrosion. It has excellent heat dissipation and sealing performance. The overall architecture of the machine and equipment is compact and easy to disassemble and maintain. At the same time, the Faraday cage 7 also facilitates the reasonable layout and fixed limit of external cables, thereby effectively suppressing crosstalk and ensuring the integrity of data transmission.
