Technical Field

[0001] The invention belongs to the technical field of network transformers, and in particular relates to a combined network transformer that is easy to replace. Background Art

Data pumps are devices available on consumer-grade PCI network cards. Data pumps are also called network transformers or network isolation transformers. It plays two main roles on a network card. One is to transmit data. It uses differential mode coupled coils to couple and filter the differential signal sent by PHY to enhance the signal, and couples it to the other end of the network cable with different levels through electromagnetic field conversion; the other is to isolate the different levels between different network devices connected by the network cable to prevent different voltages from damaging the equipment through the network cable. In addition, the data pump can also provide certain lightning protection for the equipment.

[0003] The existing network transformer is fixed by soldering. When replacing, it is necessary to first melt the tin of one PIN pin with a soldering iron, then use tweezers to lift up the PIN pin on this side to separate it from the contact piece on the mainboard, and then melt the tin of the other PIN pin. During this operation, when lifting the PIN pin, it is easy to cause the contact piece on the mainboard connected to the other PIN pin to be lifted up simultaneously due to excessive force, thus damaging the mainboard contact piece, making it impossible to install the subsequent network transformer. When disassembling the network transformer with a soldering iron, it is also easy for the soldering iron to touch the electronic components around the network transformer, causing other electronic components to shift, thereby affecting the overall maintenance efficiency.
