[0003] Currently, market switches do not have power redundancy or the ability to cascade multiple switches. They can only supply power to the switch itself. If you want to use a second or more switches, you need to supply power to them separately. Utility Model Content

[0004] In view of this, the present invention aims to propose a dual-power port switch with IP67 protection level to solve the problem in the prior art that current market switches do not have power redundancy and multiple switches can be cascaded, and can only supply power to their own switches, requiring separate power supplies.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A dual-power-port switch with IP67 protection rating includes a switch body. A flange interface 1 and a flange interface 2 are respectively installed on one end of the surface of the switch body. A plurality of network ports are installed at equal intervals on the surface of the switch body. The flange interface 1 is a power input interface, and the flange interface 2 is a power output interface. Multiple switch bodies can be cascaded sequentially through the flange interface 1 and the flange interface 2.

[0007] Furthermore, both flange interface one and flange interface two are M12 A-coding flanges.

[0008] Furthermore, the number of network ports is eight.

Network ports one, two, three and four are equally spaced from top to bottom on the left side of the switch body, and network ports five, six, seven and eight are equally spaced from top to bottom on the right side of the switch body.

[0010] Furthermore, all of the network ports 1, 2, 3, 4, 5, 6, 7, and 8 are M12-D snap flanges.

[0011] Furthermore, the switch body has mounting hole one and mounting hole two at its upper and lower ends, respectively.

[0012] Furthermore, a configuration interface is also provided on one side of the second mounting hole.

[0013] Furthermore, the outer shell seams of the switch body are fitted with rubber or silicone sealing rings for sealing.

[0014] Furthermore, the switch body is made of aluminum alloy or stainless steel.

[0015] Compared with existing technologies, the IP67-rated dual-power-port switch of this invention has the following advantages:

[0016] This utility model discloses an IP67-rated dual-power-port switch, which can be applied in fields such as metallurgical engineering, packaging machinery, and rail transportation.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] It should be noted that the existing switches contain core switching modules, power modules, and auxiliary functional components such as heat dissipation and status indicator lights. The existing core switching module is primarily responsible for data processing and forwarding. It mainly consists of a switching chip, memory unit, and network port circuitry. The switching chip uses an industrial-grade dedicated chip, supports the IEEE 802.3 standard, and implements functions such as VLAN and QoS. The memory unit includes SDRAM (data cache) and Flash (firmware storage) to ensure data forwarding efficiency. The network port circuitry provides 8 / 16 / 24 RJ45 industrial Ethernet ports with built-in surge protection and typically supports ±2kV electrostatic discharge protection. The existing power module is mainly for redundant power supply. Key components include: a power interface supporting DC 24V / 48V or AC 220V input, equipped with reverse connection protection circuitry; and a power management chip that automatically detects the status of the two power supplies for seamless switching.

[0027] like Figures 1 to 2As shown, the IP67-rated dual-power-port switch includes a switch body 1. Flange interface 2 and flange interface 3 are respectively installed on one end of the switch body 1. Several network ports 4 are equidistantly installed on the surface of the switch body 1. Flange interface 2 is a power input interface, and flange interface 3 is a power output interface. Multiple switch bodies 1 can be cascaded sequentially through flange interface 2 and flange interface 3. In this embodiment, flange interface 2 and flange interface 3 are dual power supply ports, and both flange interface 2 and flange interface 3 are M12 A-coding flanges. Four switch bodies 1 are cascaded sequentially through flange interface 2 and flange interface 3. The IP67-rated dual-power-port switch is a high-reliability network device designed specifically for harsh industrial environments, possessing complete dustproof and short-term water immersion protection capabilities.

[0028] In a preferred embodiment of this utility model, the number of network ports 4 is eight, namely network port 1 41, network port 2 42, network port 3 43, network port 44, network port 5 45, network port 6 46, network port 7 47, and network port 8 48. Network ports 1 41, 2 42, 3 43, and 44 are equidistantly arranged from top to bottom on the left side of the switch body 1, and network ports 5 45, 6 46, 7 47, and 8 48 are equidistantly arranged from top to bottom on the right side of the switch body 1. The network ports 4 are M12-D flanges. In this embodiment, the switch body 1 has two M12 A-coding flanges (power input interface and power output interface) and eight M12-D flanges (network ports). In this embodiment, the M12 A-coding flange is an M12 specification flange connector with A-coding design, mainly used for power or signal interfaces of industrial equipment. The A-code is a common type of M12 connector, typically supporting 2-17 pin configurations. It is suitable for DC power supply and sensor signal transmission, and some can be used for low-speed industrial Ethernet. Mechanical structures prevent mis-mating with other codes (such as D and X codes). It uses flange mounting (such as square / round flanges), supporting front locking or panel mounting, suitable for panel interfaces of switches, control cabinets, and other equipment, improving connection stability. It has an IP67 / IP68 protection rating, is dustproof and waterproof, and can withstand harsh industrial environments such as metallurgy and rail transportation.

[0029] In this embodiment, the eight M12-D snap-fit ​​flanges refer to the eight connectors used for network ports on a dual-power port switch with IP67 protection rating. They adopt an M12 specification, D-key snap-fit ​​flange structure. M12 refers to the M12×1 thread specification, commonly found in industrial connectors. D-key flange refers to the D-key design (preventing mis-insertion), flat flange installation method, IP67 protection rating, RoHS compliant, and suitable for network port connections in harsh industrial environments.

[0030] In a preferred embodiment of this utility model, the switch body 1 is provided with mounting hole 11 and mounting hole 12 at its upper and lower ends, respectively. A configuration interface 13 is also provided on one side of mounting hole 12. In this embodiment, mounting holes 11 and 12 are designed with metal threaded holes of M4 / M5 specification, used to fix the switch to a DIN rail, wall mount, or industrial control cabinet using screws. This structure can withstand a static tensile force of ≥50N, ensuring stable installation of the equipment under vibration and shock environments. It is a key fixed component for industrial field deployment. The configuration interface 13, based on the typical layout of industrial switches, is a Console debugging port (RS232 / RS485) or a Mini USB interface, used to connect a laptop for local configuration. The interface cover is equipped with a rubber sealing plug to maintain an IP67 protection rating.

[0031] In a preferred embodiment of this utility model, a rubber or silicone sealing ring is installed at the seam of the outer shell of the switch body 1 for sealing. The material of the switch body 1 is aluminum alloy or stainless steel. In this embodiment, professional sealing components, such as rubber / silicone sealing rings, are used at the seam of the outer shell of the switch body 1 to ensure complete dustproof and short-term water immersion protection. The M12 A-coding flange (power interface) and M12-D snap flange (network port) are both industrial connectors compliant with IP67 standards. This mechanical seal and anti-misinsertion design enhance the protection capability at the interface. The outer shell of the switch body 1 is made of metal materials such as aluminum alloy or stainless steel, which balances structural strength and sealing compatibility. The selection of sealing structure and materials ensures that the switch body 1 has stable IP67 protection capability in harsh industrial environments such as metallurgy and rail transportation.

[0032] Working principle of a dual-power-port switch with IP67 protection rating:

[0033] After power is applied, the power indicator light will illuminate; flange interface 1 (2) is connected to the power supply, and flange interface 2 (3) outputs power. It can be powered by connecting the cable of another switch body 1 (gateway) to flange interface 1 (2), and so on; after the 8 network ports 4 are connected, they can exchange and analyze previous commands to enable the switch to work.

[0034] This switch can be applied in fields such as metallurgical engineering, packaging machinery, and rail transportation. It eliminates the need for each switch to be externally powered; when multiple switches are operating, power can be supplied through one of them, ensuring normal power supply between all switches. It features dual M12 A-coding power interfaces and reduces cabling between control cabinets and machines.

[0035] This invention allows multiple switches to be connected to a single power source, which can then be cascaded to other switches via its own power supply flange, eliminating the need for additional cables. This effectively reduces the length of on-site cabling and the required space for cabling.

[0036] It should be noted that this utility model only improves the mechanical structure of the switch structure, and does not improve the control program. The control program and its electrical components involved are all existing technologies.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
