DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] Embodiment 1: A network transformer, see Figure 1-Figure 5 , including a transformer body 1, pins 2, baffles 3, iron cores 4, windings 5 and shielding covers 6. Multiple pins 2 are fixedly connected to the left and right sides of the transformer body 1, and the multiple pins 2 are evenly spaced. A baffle 3 is slidably arranged at the bottom of the transformer body 1, and a protrusion is fixedly connected to the front side of the baffle 3. The protrusion increases the contact area between the hand and the baffle 3, so as to facilitate the removal of the baffle 3. Multiple iron cores 4 are arranged at the bottom of the transformer body 1, and windings 5 are wound on the iron cores 4. A shielding cover 6 is arranged on the transformer body 1, and the shielding cover 6 absorbs electromagnetic waves and thus shields external and internal electromagnetic radiation. It also includes a first fixed block 11 and a signal amplifier 12. Two first fixed blocks 11 are arranged on the left side of the shielding cover 6 by bolt connection. A signal amplifier 12 for enhancing the signal is commonly arranged on the two first fixed blocks 11. It also includes an antenna 7. The antenna 7 is connected to the right side of the transformer body 1, and the antenna 7 is L-shaped.
[0028] When the transformer is needed, the staff puts the transformer body 1 into the network card. Then, the staff connects the network card to the electronic device to enable the transformer body 1 to run and transmit data. The shielding cover 6 absorbs electromagnetic waves, thereby shielding external and internal electromagnetic radiation, thereby preventing electromagnetic radiation from interfering with the outside world and ensuring the normal operation of the transformer body 1. The signal amplifier 12 amplifies the signal to avoid the problem of signal blind spots.
[0029] Example 2: Based on Example 1, please refer to Figure 1 and Figure 3 , also includes a heat sink 8, a fixing frame 9 and a fan 10. A plurality of heat sinks 8 are arranged on the top of the shielding cover 6. A fixing frame 9 is arranged on the top of the shielding cover 6 by bolt connection. A fan 10 is arranged inside the fixing frame 9 by bolt connection. The heat sink 8 absorbs the heat inside the transformer body 1, and the fan 10 blows the hot air to the outside. It also includes a silicone thermal pad 18. The silicone thermal pad 18 is arranged on the shielding cover 6. The silicone thermal pad 18 conducts the heat from the transformer body 1, thereby accelerating the heat dissipation.
[0030] When the transformer body 1 is in operation, heat is generated. The staff turns on the fan 10, and the heat generated by the transformer body 1 is transferred to the heat sink 8. The fan 10 rotates to blow the heat to the outside, thereby dissipating the heat of the transformer body 1, thereby preventing the normal operation of the transformer body 1 from being affected by excessive temperature.
[0031] See also Figure 1 and Figure 5 , also includes a second fixed block 13, a guide rod 14 and a card plate 15. Two second fixed blocks 13 are fixedly connected to the front side of the transformer body 1. The two second fixed blocks 13 are fixedly connected to the guide rod 14. Two card plates 15 are rotatably arranged on the guide rod 14. The card plates 15 are located at the left and right ends of the guide rod 14. The card plates 15 are rotated downward to make them disengage from the baffle 3. It also includes a torsion spring 16. The guide rod 14 is sleeved with two torsion springs 16 for resetting the card plates 15. The two ends of the torsion spring 16 are respectively connected to the card plates 15 and the guide rod 14. It also includes a guide block 17. The left and right sides of the transformer body 1 are fixedly connected with the guide blocks 17. The guide block 17 is provided with a slide groove, and the baffle 3 slides in the slide groove.
[0032] When the transformer body 1 needs to be repaired, the staff takes the transformer body 1 out of the network card, and then rotates the card plate 15 downward to make it out of contact with the baffle 3, and the torsion spring 16 is deformed accordingly, and then the baffle 3 is pulled forward to remove the baffle 3 from the bottom of the transformer body 1, and the transformer body 1 is repaired, thereby achieving the purpose of facilitating maintenance. After the maintenance is completed, the staff puts the baffle 3 back to the bottom of the transformer body 1 along the guide block 17, and the staff releases the card plate 15. The torsion spring 16 returns to its original shape to make the card plate 15 rotate upward and reset, thereby fixing the baffle 3 to the bottom of the transformer body 1.
