Abstract

The invention provides a low-loss network information transmission device. The low-loss network information transmission device comprises an enclosure, a circuit board and several pins; a network information transmission circuit is arranged on the circuit board; the network information transmission circuit comprises a first transformer, a second transformer and a signal control chip; two input ends of the signal control chip are separately connected with two input ends of the first transformer; the first transformer comprises a first magnetic core, a first primary coil wound on the first magnetic core, and a first secondary coil wound on the first magnetic core; the first primary coil is a stranded wire made of multiple strands of wires; and the first secondary coil is a stranded wire madeof multiple strands of wires. According to the low-loss network information transmission device provided by the invention, signals can be enhanced through the first transformer and the second transformer; the transmission distance is increased; therefore, the chip side is isolated from outside; the anti-interference capability is improved; the signal control chip is protected; the stranded wiresmade of multiple strands of wires are used as the first primary coil and the first secondary coil; insertion loss can be reduced; and thus, loss can be reduced.

Description

technical field [0001] The invention belongs to the technical field of information transmission, and more specifically relates to a low-loss network information transmission device. Background technique [0002] The network information transmission module is an electronic component commonly used in information transmission. The network information transmission module is a module required for a link in the two-way AC data voltage signal chain between the computer and the server. When the signal passes through this module, there will inevitably be some attenuation. Insertion loss is an indicator to measure the degree of signal attenuation. A transformer is generally used in the network information transmission module. The transformer generally includes a magnetic core and an enameled wire wound on the magnetic core. Since the transformer has a great influence on the insertion loss, the loss of the current network information transmission module is relatively large. Contents...
