Four-port 100Mbps (million bits per second) network transformer in 40 PIN encapsulation structure

Abstract

The invention discloses a four-port 100Mbps (million bits per second) network transformer in a 40 PIN encapsulation structure, and the four-port 100Mbps network transformer comprises a square insulating base, wherein the upper end of the base is provided with an opening, an upper cover is arranged above the base, a plurality of coils are arranged in the base, a row of 20 winding pins re arranged at both sides of the base, an extension piece is connected with the upper cover, bumps are arranged on the inner wall of the extension piece, and salient points matched with the bumps are arranged at both sides of the base opposite to the extension piece. The four-port 100Mbps network transformer in the 40 PIN encapsulation structure has the advantages of simple structure, simple assembling process and suitability for large-scale operation.

Description

technical field [0001] The invention relates to a network transformer, in particular to a four-port 100M network transformer with a 40PIN packaging structure. Background technique [0002] Existing network converters generally leave the bottom of the base bare and empty, and then arrange the pins around them. However, due to the small space between the pins on the horizontal plane and the PCB space of the terminal board, there will be safety problems, which will make the production process complicated and lead to solder flow. Potential adverse risks of beads and high temperature resistance. In mass production, it is difficult, and the production is often not smooth, which increases the production cost. In addition, the assembly process of the existing network transformer is complicated, and the distribution of the pins is not uniform, which leads to poor tin immersion. Contents of the invention [0003] The problem to be solved by the present invention is to provide a fo...

Problems solved by technology

[0002]Existing network converters generally leave the bottom of the base empty, and then arrange around the pins, but because the pins are on the horizontal plane, the terminal board PCB space distance is small , there will be safety problems, which will make the production process complex and the potential adverse risks of solder balling and high temperature resistance

In mass production, it is easy, and often the production is not smooth, which increases the production cost

In addition, the assembly process of the existing network transformer is complicated, and the distribution of the pins is uneven, which leads to poor tin immersion.
