Specific embodiments

[0021] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Referring in combination to Figures 1-5 , the present utility model provides a network isolation transformer, including a housing 1, a shell cover 9 bolted to the top of the housing 1, a magnetic ring assembly 4 disposed in the housing 1, and pins 5 disposed on one side of the housing 1. The shell cover 9 can be connected to the housing 1 by bolts; the magnetic ring assembly 4 is composed of a magnetic core and a coil wound around the magnetic core, and the pins 5 are used to connect the coil. The inner cavity of the housing 1 is provided with a plurality of assembly frames 2 and a plurality of heat dissipation partitions 3. The plurality of assembly frames 2 and the plurality of heat dissipation partitions 3 are arranged in an alternating manner. The arrangement of the plurality of assembly frames 2 and the plurality of heat dissipation partitions 3 can be divided into multiple regions for installing and removing the magnetic ring assembly 4, so as to avoid the problem of short circuit caused by contact between multiple magnetic ring assemblies 4. The assembly frame 2 is fixedly connected in the housing 1, and the heat dissipation partition 3 is detachably connected in the housing 1. When using the heat dissipation partition 3, due to the detachable nature of the heat dissipation partition 3, after the magnetic ring assembly 4 is installed on the assembly frame 2, the heat dissipation partition 3 is then installed into the housing 1.

[0023] The inner cavity of the housing 1 is divided into heat dissipation bending channels by a number of heat dissipation partition plates 3. The setting of the heat dissipation bending channels can concentrate the space for heat dissipation. With the housing cover 9 blocking the top of the channels, negative pressure is generated through the heat dissipation bending channels. Then, the magnetic ring assembly 4 in the heat dissipation bending channels can quickly drive heat with the flowing air, achieving a reliable heat dissipation effect. The magnetic ring assembly 4 is arranged on the mounting rack 2, and the magnetic ring assembly 4 is located in the heat dissipation bending channels. One end of the housing 1 is detachably connected with an assembly frame 6, and a dust-proof net 7 is fixedly connected to the assembly frame 6. The dust-proof net 7 can intercept dust entering the housing 1. The dust-proof net 7 is located at the head position of the heat dissipation bending channels. A suction fan 8 is arranged in the housing 1, and the suction fan 8 is located at the tail position of the heat dissipation bending channels.

[0024] A sealing gasket 10 is fixedly connected to the lower surface of the housing cover 9. With the setting of the sealing gasket 10, after the housing cover 9 is installed on the housing 1, the top of the heat dissipation bending channels can be blocked at this time. In this way, the positions of the dust-proof net 7, the heat dissipation bending channels, and the suction fan 8 can form a heat dissipation line to air-cool the magnetic ring assembly 4 arranged in the heat dissipation bending channels.

[0025] Both the mounting rack 2 and the heat dissipation partition plates 3 are made of insulating materials. The insulating materials can make the magnetic ring assembly 4 have contact insulation with the mounting rack 2 and the heat dissipation partition plates 3, so as to avoid the problem of short circuit of the magnetic ring assembly 4.

[0026] One end of the heat dissipation partition plate 3 is fixedly connected with a second plug connector 12. The heat dissipation partition plate 3 is tightly inserted into the inner wall of the housing 1 through the second plug connector 12. A gap is reserved between the other end of the heat dissipation partition plate 3 and the inner wall of the housing 1. The setting of the gap can facilitate the air flow path at the bending part of the heat dissipation bending channels, so that air can enter the housing 1 at the position of the dust-proof net 7 and flow in a bent manner; in this application, the second plug connector 12 can be made of rubber material. While meeting the convenience of disassembling the heat dissipation partition plate 3, it can improve the connection tightness to ensure the airtightness of the air flow in the heat dissipation bending channels.

[0027] Mounting grooves 14 are formed on the mounting rack 2, and the magnetic ring assembly 4 is fixedly connected in the mounting grooves 14. The magnetic ring assembly 4 arranged in the mounting grooves 14 is suspended in the housing 1. The setting of the mounting grooves 14 can be used to distribute the installation positions of the magnetic ring assembly 4 to reserve a safety distance; and the suspended setting can make the flowing air fully contact the magnetic ring assembly 4 to ensure the comprehensiveness of heat dissipation.

[0028] First plug connectors 11 are fixedly connected to both ends of the assembly frame 6. The assembly frame 6 is tightly inserted into the inner wall of one end of the housing 1 through the first plug connectors 11. In this application, the first plug connectors 11 also adopt rubber materials. The plugging method of the first plug connectors 11 provides convenience for disassembling the assembly frame 6, so that the dust-proof net 7 can be easily removed for cleaning.

[0029] A filter screen 13 is provided on one side of the housing 1. The filter screen 13 corresponds to the tail position of the heat dissipation bending channel. Since the exhaust fan 8 performs a negative pressure exhaust function on the heat dissipation bending channel, external air enters through the position of the dust-proof net 7. Therefore, the dust-proof net 7 needs to be cleaned more. The filter screen 13 is arranged near the exhaust fan 8, and its main function is to prevent foreign objects from entering the heat dissipation bending channel, so the filter screen 13 does not need to be disassembled.
