Description

Technical Field

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

[0002] The main distinctions between existing RJ (Registered Jack) connectors are RJ11 and RJ45 connectors. The difference lies in the size of the RJ45 connector, which is larger than that of the RJ11 connector. The RJ45 connector also 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 are constantly increasing from 155M to 1G, 2.5G, 10G, etc.; however, the higher the communication speed of the existing 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 existing RJ45 connector to interfere with each other.

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

[0007] The present invention provides an electrical connector structure, particularly for connecting to a pre-set RJ45 cable connector, wherein the RJ45 cable connector has an elastic snap-fit ​​element at its top.

The tongue portion of the insulating base is located in the insertion space, and the front ends of the two light guide pillars protrude from the insulating housing. A metal baffle is movably connected to the metal housing and is attached to the bottom of the metal housing. The control circuit board has a first soldering pin group, a second soldering pin group, and a third soldering pin group on one surface.

The first to eighth signal contacts extend from 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.

[0010] The base of the insulating base and the signal connector are respectively attached to both ends of the control circuit board. The first to eighth signal pins of the signal terminal group and the five grounding pins of the grounding terminal group are electrically connected to the first soldering pin group. The first signal connection terminal group of the signal connector is electrically connected to the third soldering pin group. Furthermore, the primary and secondary terminal groups of the transformer module are electrically connected to the second soldering pin group, thus forming an electrical connection between the signal terminal group, the grounding terminal group, the transformer module, and the signal connector. Finally, a metal shell and a metal baffle cover the insulating shell, the control circuit board, the signal connector, and the transformer module.

[0011] Therefore, by arranging the first to eighth signal solder pins and the five ground solder pins side by side on the same axis, the soldering process of electrical connectors can be effectively simplified, thereby reducing the processing time. Attached Figure Description

[0042] This invention illustrates the terminal structure of signal terminal group 1 and the arrangement relationship between signal terminal group 1 and ground terminal group 2 (please refer to the accompanying documentation). Figure 6 , Figure 7As shown), wherein: a first signal terminal 11 has a first signal solder pad 111 at one end and a first signal contact portion 112 at the other end, and a first signal section 113 is provided between the first signal solder pad 111 and the first signal contact portion 112; a second signal terminal 12 has a second signal solder pad 121 at one end and a second signal contact portion 122 at the other end, and a second signal section 123 is provided between the second signal solder pad 121 and the second signal contact portion 122; a third signal terminal 13 has a third signal solder pad 131 at one end and a third signal contact portion 132 at the other end, and a third signal section 133 is provided between the third signal solder pad 131 and the third signal contact portion 132; a fourth signal terminal 14 has a fourth signal solder pad 141 at one end and a fourth signal contact portion 142 at the other end, and a fourth signal section is provided between the fourth signal solder pad 141 and the fourth signal contact portion 142. 143; The fifth signal terminal 15 has a fifth signal solder foot 151 at one end and a fifth signal contact portion 152 at the other end, and a fifth signal section 153 is provided between the fifth signal solder foot 151 and the fifth signal contact portion 152; The sixth signal terminal 16 has a sixth signal solder foot 161 at one end and a sixth signal contact portion 162 at the other end, and a sixth signal section 163 is provided between the sixth signal solder foot 161 and the sixth signal contact portion 162; The seventh signal terminal 17 has a seventh signal solder foot 171 at one end and a seventh signal contact portion 172 at the other end, and a seventh signal section 173 is provided between the seventh signal solder foot 171 and the seventh signal contact portion 172; The eighth signal terminal 18 has an eighth signal solder foot 181 at one end and an eighth signal contact portion 182 at the other end, and an eighth signal section 183 is provided between the eighth signal solder foot 181 and the eighth signal contact portion 182.

[0043] The first signal solder pin 111, the second signal solder pin 121, the third signal solder pin 131, the fourth signal solder pin 141, the fifth signal solder pin 151, the sixth signal solder pin 161, the seventh signal solder pin 171, the eighth signal solder pin 181, and the five grounding solder pins 21 are arranged in the same direction and on the same axis, and their arrangement order is as follows: one grounding solder pin 21, the first signal solder pin 111, the second signal solder pin 121, one grounding solder pin 21, the fourth signal solder pin 141, the fifth signal solder pin 151, one grounding solder pin 21, the third signal solder pin 131, the sixth signal solder pin 161, one grounding solder pin 21, the seventh signal solder pin 171, the eighth signal solder pin 181, and the last grounding solder pin 21.

[0044] The design utilizes two grounding solder pins 21 positioned at the left and right ends of the first signal solder pin 111 and the eighth signal solder pin 181, respectively, as shielding.

[0048] The insulating base 3 has multiple perforated holes 321 on the top and bottom surfaces of the tongue plate portion 32, with each perforated hole 321 corresponding to the positions of the first signal segment 113, the second signal segment 123, the fourth signal segment 143, the fifth signal segment 153, the third signal segment 133, the sixth signal segment 163, the seventh signal segment 173, and the eighth signal segment 183 (e.g., ...). Figure 5 , Figure 8 , Figure 9 As shown), the first to eighth signal segments 113, 123, 133, 143, 153, 163, 173, and 183 are relatively exposed to the outside, thereby relatively increasing the impedance of the signal terminal group 1.

[0049] In summary, by arranging the first signal solder pin 111, the second signal solder pin 121, the third signal solder pin 131, the fourth signal solder pin 141, the fifth signal solder pin 151, the sixth signal solder pin 161, the seventh signal solder pin 171, the eighth signal solder pin 181, and the five grounding solder pins 21 in the same direction and on the same axis, the soldering process of the electrical connector can be simplified, thereby reducing the processing time. At the same time, by arranging the first to eighth signal solder pins 111, 121, 131, 141, 151, 161, 171, 181, and the five grounding solder pins 21 in an alternating manner, the mutual interference of electromagnetic waves between the first to eighth signal terminals 11, 12, 13, 14, 15, 16, 17, and 18 can be effectively reduced.
