Summary of the invention

[0004] The object of the present invention is to provide a rack-mounted reinforced industrial Ethernet switch to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a rack-mounted reinforced industrial Ethernet switch, comprising a casing, and also comprising a protective structure and a circuit protection structure; the protective structure comprises a control panel, a shielding cover plate, a slide rail, and a side guide plate, the slide rail is fixedly connected to the inner wall of the casing, the side guide plate is slidably connected to the inner side of the slide rail, the control panel is fixedly connected to the front side of the side guide plate, and the shielding cover plate is fixedly connected to the inner side of the control panel; the module structure comprises a memory slot shell, a hard disk slot shell, a heat dissipation end, a power supply, a mainboard, a power-on end, an electromagnet, a magnetic lift, a contact end, and a power-on fixed plate, the memory slot shell is slidably connected to the left side of the casing, the hard disk slot shell is slidably connected to the right side of the casing, the heat dissipation end is slidably connected to the left end bottom surface of the casing, the power supply is slidably connected to the right end bottom surface of the casing, the mainboard is arranged at the inner top of the casing, the power-on end is fixedly connected to the side of the power-on fixed plate, the electromagnet is fixedly connected to the left side of the power-on end, the magnetic lift is arranged at the left end of the power-on end, and the contact The end is arranged on the left side of the magnetic lift piece, and the power-carrying fixed plate is fixedly connected to the inner bottom surface of the casing; the bottom surface of the power-carrying end is fixedly connected with a frame plate, and the magnetic lift piece is rotatably connected to the frame plate, the contact end is fixedly connected to the frame plate, and the contact end is electrically connected to the mainboard through a wire, and a torsion spring is arranged on the bottom side of the rotating shaft of the magnetic lift piece, and the magnetic lift piece is electrically connected to the power-carrying end through a wire. Through the above structure, when a short circuit occurs in the internal circuit of the mainboard, the current in the series circuit will increase, so that the current passing through the power-carrying end enters the electromagnet. The increased current will increase the magnetism of the side of the electromagnet, and the magnetism will cause the electromagnet to attract the magnet on the side of the magnetic lift piece, so that the magnetic lift piece deflects and separates from the contact end, disconnecting the access circuit to play a protective role. At the same time, the memory slot shell and the hard disk slot shell are installed and disassembled by sliding with the casing, and the components that originally need to be disassembled and replaced are replaced in a modular manner. The above scheme is adopted for the heat dissipation end and the power supply, which is convenient for disassembly to prevent component damage from causing bad circuits in the mainboard, and convenient for replacement at any time to avoid bad circuits and affect the normal operation of the function.

[0006] According to the above technical solution, a ventilation device is provided between the mainboard and the heat dissipation end, and the ventilation device includes an exhaust fan, an exhaust duct, a sub-item exhaust duct, a guide plate, a copper tube, an air inlet duct, a weak magnetic block, a strong magnetic block, and a push rod.

Through the above structure, the heat dissipation end 10 is connected to the mainboard 12 After the connection, the power supply 11 supplies power to the powered fixing plate 18, and then the powered fixing plate 18 supplies power to the heat sink 10. When the heat sink 10 is in operation, the exhaust fan 51 and the small fan in the heat sink 10 start to operate, and the outside air enters the inside of the housing 1 through the air inlet 56, while the air inside the housing 1 is drawn in through the two sides of the sub-item exhaust channel 53, and the shielding cover plate 7 is attached to the side of the sub-item exhaust channel 53 to isolate the air inlet 56 in front. The mesh structure of the shielding cover plate 7 can be used to shield the external electrical signal, and the mesh structure can be used to filter to prevent dust from entering the interior along with the air and entering the sub-item exhaust channel 53.

At the same time, the memory slot shell 3 and the hard disk slot shell 4 are installed and disassembled by sliding with the case 1, and the components that originally need to be disassembled and replaced are replaced in a modular manner. The above scheme is adopted for the heat dissipation terminal 10 and the power supply 11, which is convenient for disassembly, prevents component damage from causing a bad circuit in the mainboard 12, and is convenient for replacement at any time to avoid the occurrence of a bad circuit to avoid affecting the normal operation of the function;

[0028] Power is supplied to the powered fixing plate 18 through the power supply 11, and then power is supplied to the heat dissipation end 10 through the powered fixing plate 18.

The mesh structure of the shielding cover plate 7 can be used to shield the external electrical signal, and the mesh structure can be used to filter to prevent dust from entering the interior along with the air, and the air entering the sub-item exhaust duct 53 The heat accumulated on the copper tube 55 is taken away by the flow guide plate 54 to prevent the internal temperature from being too high. At the same time, when a fault occurs inside the heat dissipation end 10, the heat collected at the copper tube 55 will be transferred to the fixed weak magnetic block 57. By increasing the temperature, the weak magnetic block 57 will be reduced as the temperature rises, and then the weak magnetic block 57 will reduce its magnetism and break away from the adsorption of the strong magnetic block 58. Under the action of the spring tension, the copper tube 55 will be quickly triggered to drive the deflector plate 54 to deflect, and the deflector plate 54 will hit the push rod 59.
