Description

[Technical Field]

[0001] This invention relates to the technical field of electrical connector structures, and more particularly to an electrical connector that connects to the connector of an RJ45 cable, having staggered and side-by-side first to eighth signal pins and five ground pins. [Previous Technology]

[0002] It is known that RJ (Registered Jack) connectors are mainly distinguished into RJ11 connectors and RJ45 connectors. The difference is that the size of the RJ45 connector is larger than that of the RJ11 connector, and the RJ45 connector has eight contact terminals to meet the needs of computer networks or digital communications.

[0003] As the demand for communication bandwidth and speed continues to increase, for example, the communication speed has been continuously increased from 155M to 1G, 2.5G, 10G, etc.; however, the higher the communication speed of the conventional RJ45 connector, the higher the electromagnetic waves generated by the eight contact terminals, which causes the electromagnetic waves generated by the eight contact terminals of the conventional RJ45 connector to interfere with each other.

[0004] In addition, the soldering pins of the eight contact terminals of the conventional RJ45 connector are all designed in a distributed manner, that is, the eight soldering pins of the conventional RJ45 connector are not on the same axis, which also makes the soldering process of the conventional RJ45 connector quite cumbersome and inconvenient.

[0005] Therefore, the present invention aims to solve the problem of how to provide an RJ45 connector socket with staggered and side-by-side first to eighth signal solder pins and five ground solder pins to reduce mutual interference between the eight contact terminals, while simplifying the soldering process and reducing the processing time. [Summary of the Invention]

The first to eighth signal contacts extend from the front end of the tongue portion of the insulating base and are positioned opposite each other in the insertion space of the insulating shell. The first to eighth signal solder feet and the five grounding solder feet are arranged alternately in the same direction and on the same axis.

[0009] The base of the insulating base and the signal connector are respectively attached to the two ends of the control circuit board.

The first signal connection terminal group of the signal connector is electrically connected to the third solder pin group.

Furthermore, the insulating housing, the control circuit board, the signal connector, and the transformer module are covered by a metal shell and a metal baffle.

[0010] Therefore, by arranging the first to eighth signal solder pins and the five ground solder pins side by side on the same axis, the process of soldering electrical connectors can be effectively simplified, thereby reducing the time required for the process.
