Description

Technical Field

[0001] This utility model belongs to the field of network equipment technology, specifically referring to a network transformer that can support external power supply. Background Technology

[0002] The primary function of a network transformer is to isolate, filter, and transmit signals through magnetic coupling; it does not involve a power supply. The working principle of a network transformer is to enhance signals through electromagnetic field conversion and filter noise and interference through differential-mode coupled coils, ensuring stable signal transmission. Most network transformers do not require external power. However, when integrated with other electronic devices, an external power supply is needed to drive their internal circuits or provide the necessary operating voltage to ensure normal operation; most of these external power supplies incorporate built-in batteries.

[0003] However, when the built-in battery of the existing network transformer fails to function properly, it will stop operating due to power failure, causing network communication interruption and causing great inconvenience to users. It is necessary to replace the built-in battery or network transformer, resulting in a long-term network interruption and affecting the normal use of the network. Utility Model Content

[0004] In response to the above situation and to overcome the shortcomings of the existing technology, this utility model proposes a network transformer that can support external power supply. This effectively solves the problem that when the built-in battery of the network transformer fails to function properly, it will stop operating due to power failure, resulting in network communication interruption, causing great inconvenience to users, requiring the replacement of a new built-in battery or network transformer, causing long-term network interruption, and affecting the normal use of the network.

[0005] The technical solution adopted by this utility model is as follows: This utility model proposes a network transformer that can support external power supply, including a base and a transformer structure. The transformer structure is disposed on the base. The transformer structure includes a transformer unit and an external power supply unit. The transformer unit is disposed on the base, and the external power supply unit is electrically connected to the transformer unit.

[0006] The transformer unit includes a network transformer body, pin wires, a device housing, a built-in battery, and a working indicator light. The network transformer body is fixedly mounted on a base. The pin wires pass through the base and are electrically connected to the network transformer body. The device housing covers the network transformer body and is fixedly mounted on the base. The built-in battery is electrically connected above the partition of the network transformer body and located inside the device housing. The working indicator light is electrically connected to the circuit of the network transformer body and is fixedly mounted above the partition of the network transformer body.

[0007] Preferably, the external power supply unit includes a circuit board, a charging cable, an overvoltage protector, an overcurrent protector, a power bank USB port, indicator light one, a DC plug, and indicator light two. The circuit board is fixedly mounted on the partition of the network transformer body and located inside the device housing. One end of the charging cable is electrically connected to the circuit board, and the other end is electrically connected to the built-in battery. The overvoltage protector is electrically connected to the circuit on the circuit board. The overcurrent protector is electrically connected to the circuit on the circuit board. The power bank USB port passes through the top of the device housing and is electrically connected to the circuit on the circuit board. Indicator light one passes through the top of the device housing and is electrically connected to the circuit on the circuit board. The DC plug passes through the top of the device housing and is electrically connected to the circuit on the circuit board. Indicator light two passes through the top of the device housing and is electrically connected to the circuit on the circuit board.

[0008] To better achieve the effect of external power supply, the circuit board is equipped with both DC and AC circuits to adapt to various power supplies.

[0009] To achieve stable power supply more quickly, the overvoltage protector is used to regulate the voltage or cut off the power supply when the voltage exceeds the safe range, ensuring equipment safety. The overcurrent protector is used to automatically cut off the power supply when the current exceeds a set threshold, preventing damage to the network transformer and network equipment due to excessive current.

[0010] Furthermore, the USB port and indicator light one of the power bank are located in the DC circuit, while the DC plug and indicator light two are located in the AC circuit.

[0011] The beneficial effects of this utility model using the above structure are as follows: The proposed solution provides a network transformer that can support external power supply, and is equipped with a mobile power supply USB port and a DC power plug to enable multiple power supply methods, ensuring that the network transformer itself works normally without interruption and without affecting the user's normal use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention proposes a network transformer that can support an external power supply, including a base 1 and a transformer structure 2. The transformer structure 2 is disposed on the base 1. The transformer structure 2 includes a transformer unit 3 and an external power supply unit 4. The transformer unit 3 is disposed on the base 1, and the external power supply unit 4 is electrically connected to the transformer unit 3.

[0020] The transformer unit 3 includes a network transformer body 5, pin wires 6, a housing 7, a built-in battery 8, and a working indicator light 9. The network transformer body 5 is fixedly mounted on the base 1. The pin wires 6 pass through the base 1 and are electrically connected to the network transformer body 5. The housing 7 covers the network transformer body 5 and is fixedly mounted on the base 1. The built-in battery 8 is electrically connected to the partition of the network transformer body 5 and is located inside the housing 7. The working indicator light 9 is electrically connected to the circuit of the network transformer body 5 and is fixedly mounted to the partition of the network transformer body 5.

[0021] like Figure 1 , Figure 3 and Figure 4As shown, the external power supply unit 4 includes a circuit board 10, a charging cable 11, an overvoltage protector 12, an overcurrent protector 13, a power bank USB port 14, an indicator light 15, a DC power plug 16, and an indicator light 17. The circuit board 10 is fixed on the partition of the network transformer body 5 and located inside the device housing 7. The circuit board 10 has both DC and AC circuits to adapt to various power supplies. One end of the charging cable 11 is electrically connected to the circuit board 10, and the other end is electrically connected to the built-in battery 8. The overvoltage protector 12 is electrically connected to the circuit on the circuit board 10. The overvoltage protector 12 is used to regulate the voltage or cut off the power supply when the voltage exceeds the safe range to ensure device safety. The overcurrent protector 13 is electrically connected to the circuit board 10. In the circuit of circuit board 10, overcurrent protector 13 is used to automatically cut off the power supply when the current exceeds the set threshold to prevent damage to the network transformer body 5 and network equipment due to excessive current. The power bank USB port 14 passes through the top of the device housing 7 and is electrically connected to the circuit of circuit board 10.

[0022] In practical use, the pins on both sides are first connected to the Ethernet device, thereby enhancing the signal through the network transformer body 5. Differential-mode coupled coils filter noise and interference, ensuring stable signal transmission. For the network transformer body 5 to stably enhance the signal, an external power supply is required. The electrical energy stored in the built-in battery 8 is applied to the network transformer body 5 and converted into a magnetic field to enhance the signal. When the built-in battery 8 malfunctions, has low power, or cannot store electricity, an external power supply is needed to maintain stable operation of the network transformer body 5. Therefore, a power bank can be connected via the USB port 14. When the circuit is powered on, the current is transmitted through the circuit board 10. At this time, indicator light 15 lights up, indicating that the working status is normal. At this time, the current flows through the charging cable 11 to the built-in battery 8, and then through the built-in battery 8 to the network transformer body 5. Alternatively, a DC power supply can be plugged in through the DC plug 16, and the current is transmitted through the circuit board 10. At this time, indicator light 17 lights up, indicating that the working status is normal. The current flows through the charging cable 11 to the built-in battery 8, and then through the built-in battery 8 to the network transformer body 5, thus ensuring that the network transformer body 5 always works normally. The above is the entire usage process of the network transformer that supports external power supply.
