Embodiment Construction

[0019] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0020] Such as figure 1 As shown in , it is a schematic diagram of a network isolation transformer included in the network port, and the network isolation transformer contains a resistor network inside. J1, J2, J3, J4, J5, J6, J7, and J8 are the pins of the network port with network isolation transformer. The network isolation transformer is also called the network transformer. It is a magnetic component that connects the Ethernet chip (10 / 100 / 1000) and the terminal network port (RJ45). Its main functions are signal transmission, impedance matching, waveform repair, Clutter suppression and high voltage isolation. The network isolation transformer and the network port can be two independent components, or an integrated component with a network isolation transformer in the network port. The internal circuits of different types of network ...

Abstract

The invention relates to the field of anti-theft technology, in particular to an anti-theft method by making use of the features of a network isolation transformer in network apparatus. The anti-theft method is realized by making use of the characteristics of resistance network and inductive choke of the internet isolation transformer. An anti-theft device designed by utilizing the method can solve the anti-theft problem of most network equipment. If being used for equipment such as a network switch or a hub and the like, the method has wider market prospect.

Description

Technical field [0001] The invention relates to the field of anti-theft technology, in particular to a method for anti-theft by utilizing the characteristics of a network isolation transformer in network equipment. Background technique [0002] There are network isolation transformers in network equipment. Network isolation transformers are also called network transformers. It is a magnetic component that connects the Ethernet chip (10 / 100 / 1000) and the terminal network port (RJ45). Its main function is to act as a signal Transmission, impedance matching, waveform repair, clutter suppression, and high voltage isolation. The network isolation transformer and the network port can be two independent components, or an integrated component with a network isolation transformer in the network port. The internal circuits of different types of network isolation transformers from different companies are different, but they all have one thing in common, that is, they contain inductanc...
