Description

Technical Field

[0001] This utility model relates to the field of ruggedization and electromagnetic information protection technology, and in particular to a low-leakage ruggedized switch. Background Technology

[0002] With the rapid development of the information industry, the interconnection between devices is becoming increasingly common, placing higher demands on the number of switch ports and transmission rates. Rugged 1U chassis that meet low-leakage requirements are often limited by height, resulting in a limited number of connection ports, which cannot meet the needs of modern battlefields. To achieve the high-performance transmission requirements of 48 network ports and 4 fiber optic ports, traditional equipment, constrained by rack size requirements, typically uses a dual-layer RJ45 port layout, with ports soldered directly from the motherboard to the rear panel of the chassis. This often sacrifices the equipment's electromagnetic interference resistance and information shielding. Since switches are the central hub for connecting data and information exchange between devices, they themselves generate strong electromagnetic radiation and carry large amounts of data. If left uncontrolled, this electromagnetic radiation can be easily intercepted and reproduced, leading to equipment damage or information theft.

[0003] There is an urgent need for a high-performance, low-leakage ruggedized 1U 48-port switch with high transmission speed, multiple connection ports, and compliance with electromagnetic interference and shielding requirements. This switch must meet the high-performance transmission requirements of 48 network ports and 4 10 Gigabit optical ports within the space constraints of a 1U form factor, preventing information leakage and external electromagnetic interference. Furthermore, it needs to be designed for use in harsh outdoor environments with a portable trolley chassis; therefore, the device must also meet shock and vibration requirements, as well as certain dust and water resistance requirements.

[0004] To address the aforementioned problems, this invention provides a low-leakage ruggedized switch to solve the issues of poor electromagnetic protection and weak anti-interference capabilities of previous switches. Utility Model Content

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.

[0029] The purpose of this invention is to provide a low-leakage ruggedized switch to improve electromagnetic protection and anti-interference capabilities.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] refer to Figures 1 to 8A low-leakage ruggedized switch includes a chassis, a management interface, mode button, power switch, guide pins, a power input connector, a fuse, an optical port connector, a network port connector, and a grounding post, all mounted on the outer wall of the chassis. Inside the chassis are network port cards, heat sinks, a switching motherboard, a power module, a filter, a filter cover, and a fan mechanism. The chassis includes a top cover, a bottom plate, a front panel, and side panels. Each of the side panels, front panel, and rear panel has a first groove containing a silver-plated aluminum conductive rubber strip. Second grooves are located at both ends of the side panels, containing first shielding rubber plates. The network port connector and the optical port connector are both located on the rear panel. A second shielding rubber plate and a third shielding rubber plate are respectively provided between the rear panel and the network port connector and the optical port connector. A beryllium copper spring is provided at the junction of the filter cover and the chassis. The power supply lines and data transmission signal lines on the motherboard are printed separately. All cables inside the chassis are shielded cables. This utility model has made a large number of conductive shielding overlaps between the internal cables and the chassis to form an electromagnetic shielding cavity. This enables high performance, small size, and input / output functions of 48 network ports and 4 optical ports in a 1U height size. It achieves the purpose of anti-electromagnetic interference and anti-vibration. It solves the problems of electromagnetic shielding, dust and water resistance, and heat dissipation in a confined internal space that were not available in previous models of this height size.

[0032] refer to Figure 1 The management interface is a 1C type connector and is located on the front panel. The management interface is used to configure the initial network port of the switching motherboard locally, which facilitates the connection and debugging of equipment. The management interface adopts the 1C type connector, which is not only compact and small in structure, but also dustproof and waterproof.

[0033] refer to Figure 1 The front panel also features 48 network port indicator lights and status indicator lights, clearly displaying the connection and operation status of each port.

[0034] Furthermore, conductive rubber pads are provided at the connection points between the management interface, mode button, and power switch button and the front panel; these pads serve to provide waterproofing while also allowing for electrical connection to the front panel. Shielded cables are used. The fundamental purpose is to achieve high-speed, high-performance transmission with 48 ports and 4 optical ports within a 1U chassis, while also meeting waterproofing and electromagnetic compatibility requirements.

[0035] refer to Figure 2Both the network port connector and the optical port connector are located on the rear panel. A second shielding rubber pad and a third shielding rubber pad are respectively provided between the rear panel and the network port connector and the optical port connector; these serve to conduct electricity, shield, and seal. The network port connector adopts a micro-circular high-density electrical connector structure with a straight push-in and pull-out structure, suitable for high-density installation and installation in relatively small spaces. One network port connector can realize the connection of 8 network ports, and 6 network port connectors can meet 48 network connections. One optical port connector can realize the high-speed transmission of two optical ports, and installing two can realize the transmission of 4 10 Gigabit optical ports. The connector structure is small in size and light in weight, can realize quick connection and disconnection, is easy to operate, and has reliable connection. The shell is made of stainless steel, which has good anti-mildew and anti-dust properties.

[0036] refer to Figures 6 to 7 A heat dissipation protrusion is located between the base plate and the switching motherboard, and a thermal pad is attached to it. Heat is conducted to the heatsink fins above, and then carried out of the chassis by two exhaust fans mounted on the front panel. These fans are speed-adjustable exhaust fans, allowing the fan speed and airflow to be adjusted according to the motherboard's power and heat generation. Furthermore, a heatsink is located in the chip area above the motherboard, transferring heat in two directions within the small 1U interior space via its upper and lower surfaces.

[0037] refer to Figures 6 to 7 The fan mechanism includes an exhaust fan, a fan dust filter frame, a fan dust filter, a side panel dust filter frame, and a side panel dust filter. The exhaust fan is mounted on the front panel and is used to remove heat from the chassis. Ventilation holes are provided on both sides of the side panel. The side panel dust filter frame presses the side panel dust filter onto the side panel. The exhaust fan, fan dust filter frame, and fan dust filter are all pressed onto the side panel. This mechanism can create negative pressure inside the chassis, allowing cool external air to continuously enter the chassis and be removed by the exhaust fan on the front panel, thus meeting the requirements for high performance and high heat dissipation.

[0038] Furthermore, the chassis houses a switching motherboard with power supply and data transmission signal lines printed separately to achieve electromagnetic isolation and prevent interference. The power input connector is connected to a filter, which is further shielded from external electromagnetic signals. Beryllium copper springs are attached to the junction of the filter and the chassis to ensure a shielded cavity. All internal cables are shielded, ensuring reliable grounding of the cable shielding layer and adhering to the principle that power cables do not cross with signals transmitted from other network ports.

[0039] Furthermore, the chassis is made of magnesium-aluminum alloy, which greatly reduces the weight of the chassis and is treated with conductive oxidation. The outer surface is painted, and all surfaces inside except the overlapping surfaces are coated with conformal coating. The motherboard and power module are coated with conformal coating, all fasteners are soaked in anti-rust oil, and all aviation connectors are equipped with waterproof and dustproof covers.

[0040] refer to Figure 2 The circuit boards inside the chassis are screwed onto the blind hole studs on the base plate. The cable connection between the power module and the switching motherboard is treated with adhesive to prevent the connectors from becoming loose. The connection between the network port plug and the switching motherboard is reinforced with network cable clips to prevent the connectors from falling off or becoming loose due to impact and vibration. Since there are a lot of 48 network cables, the cables are bundled in groups with nylon tape and tied to the blind hole nuts on the base plate.

[0041] Any adaptive changes made according to actual needs are within the protection scope of this utility model.

[0042] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered as exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
