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. Prior Technology

[0002] RJ (Registered Jack) connectors are mainly distinguished into RJ11 connectors and RJ45 connectors. The difference is that the RJ45 connector is larger than the RJ11 connector and 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, communication speeds have been continuously increasing 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 makes the soldering process of the conventional RJ45 connector quite cumbersome and inconvenient.

[0005] Therefore, the problem to be solved by this invention is to provide an RJ45 connector socket with staggered and side-by-side first to eighth signal solder pins and five ground solder pins, so as to reduce mutual interference between the eight contact terminals and simplify the soldering process to reduce the processing time. Summary of the Invention

[0006] The main objective of this invention is to provide an electrical connector structure, particularly for connecting to a pre-defined RJ45 cable connector. The electrical connector structure of this invention includes a signal terminal group and a grounding terminal group.

[0007] The signal terminal group is disposed inside the electrical connector and includes a first to an eighth signal terminal. The first signal terminal has a first signal solder pad at one end, the second signal terminal has a second signal solder pad at one end, the third signal terminal has a third signal solder pad at one end, the fourth signal terminal has a fourth signal solder pad at one end, the fifth signal terminal has a fifth signal solder pad at one end, the sixth signal terminal has a sixth signal solder pad at one end, the seventh signal terminal has a seventh signal solder pad at one end, and the eighth signal terminal has an eighth signal solder pad at one end.

[0008] The grounding terminal group is located inside the electrical connector and includes at least five grounding solder pins.

[0009] The first to eighth signal solder pins and the five ground solder pins are arranged in the same direction, and the arrangement of the first to eighth signal solder pins and the five ground solder pins is as follows: one ground solder pin, the first signal solder pin, the second signal solder pin, one ground solder pin, the fourth signal solder pin, the fifth signal solder pin, one ground solder pin, the third signal solder pin, the sixth signal solder pin, one ground solder pin, the seventh signal solder pin, the eighth signal solder pin, and one ground solder pin.

[0010] Therefore, the technical feature of this invention is that two grounding solder pins are respectively set at the left and right ends of the first to eighth signal solder pins as shielding, and three grounding solder pins are respectively staggered between every two signal solder pins as shielding. Through this arrangement design, the first to eighth signal solder pins and five grounding solder pins can be staggered and arranged side by side, thereby reducing the mutual interference of electromagnetic waves between the first to eighth signal terminals.

[0011] Furthermore, by arranging the first to eighth signal solder pads and the five ground solder pads side by side on the same axis, the soldering process can be effectively simplified, thereby reducing the processing time. Simple Explanation of the Diagram

Furthermore, three grounding solder pads 21 are staggered between every two signal solder pads as shielding. This arrangement allows the first to eighth signal solder pads 111, 121, 131, 141, 151, 161, 171, and 181, along with the five grounding solder pads 21, to be arranged side-by-side in a staggered manner, thereby reducing electromagnetic interference between the first to eighth signal terminals 11, 12, 13, 14, 15, 16, 17, and 18.
