Through the above description, we can understand the structure of this technology, and according to the corresponding cooperation of this structure, it can also achieve the advantages of optimizing signal quality, reducing the occurrence of common mode noise, and suppressing electromagnetic wave radiation interference or radio frequency interference. The explanation will be explained below.

Specifically, because the front-row contact points of the female transmission conductor set 11 are also composed of the first high-frequency differential signal contact portion 213, the second high-frequency differential signal contact portion 223, the second power circuit contact portion 323, and the first The ground contact portion 531, the third high frequency differential signal contact portion 613, and the fourth high frequency differential signal contact portion 623 are arranged in sequence, and are connected by the second power circuit contact portion 323 and the first ground contact portion 531 The same PIN is formed and the terminal characteristics are the same, so it is equivalent to the 7th PIN GND_DRAIN of the conventional USB 3.0 connector. As for the second row of contact points of the female transmission conductor set 11, the first high-frequency differential signal holding portion 212, the second high-frequency differential signal holding portion 222, the first power circuit contact portion 313, and the second power circuit are held. 322, the first low-frequency differential signal contact portion 413, the second low-frequency differential signal contact portion 423, the ground holding portion 52, the second ground contact portion 532, the third high-frequency differential signal holding portion 612, and the fourth high The frequency differential signal holding parts 622 are arranged in sequence, and only the first power circuit contact part 313, the first low frequency differential signal contact part 413, the second low frequency differential signal contact part 423, and The second ground contact 532. Therefore, the arrangement sequence of the front-row contact portions and the second-row contact portions of the female transmission conductor set 11 conforms to the USB 3.0 specification.

And the arrangement sequence of the contact points of the second row of the female transmission conductor set 11 is the same as the arrangement sequence of the welding points because the first ground contact portion 531 and the second ground contact portion 532 extend from the ground holding portion 52 and extend to the welding end There is only one ground welding part 51, so that the welding points of the female transmission conductor group 11 are arranged in the first high-frequency differential signal welding part 211, the second high-frequency differential signal welding part 221, and the first power circuit welding part 311 , The second power circuit welding part 321, the first low frequency difference The moving signal welding part 411, the second low frequency differential signal welding part 421, the ground welding part 51, the third high frequency differential signal welding part 611, and the fourth high frequency differential signal welding part 621. In this arrangement sequence, the first high-frequency differential signal transmission conductor pair 2 (the first high-frequency differential signal welding portion 211 and the second high-frequency differential signal welding portion 221), the power circuit transmission conductor pair 3 (the first The power circuit welding part 311, the second power circuit welding part 321), the low frequency differential signal transmission conductor pair 4 (the first low frequency differential signal welding part 411, the second low frequency differential signal welding part 421), and the second high frequency The pair of differential signal transmission conductors 6 (the third high-frequency differential signal welding part 611 and the fourth high-frequency differential signal welding part 621) are each arranged in pairs by two terminals, so the purpose of each coupling can be achieved.

And through the arrangement sequence of the first high-frequency differential signal transmission conductor pair 2, the power circuit transmission conductor pair 3, the low-frequency differential signal transmission conductor pair 4, the ground transmission conductor 5 and the second high-frequency differential signal transmission conductor pair 6, In order to avoid improper coupling between the power circuit transmission conductor pair 3 and the adjacent first high-frequency differential signal transmission conductor pair 2 or the low-frequency differential signal transmission conductor pair 4, common mode phenomenon occurs, thereby improving signal quality and avoiding The common mode of the radio frequency signal will further reduce electromagnetic interference and radio frequency interference.

Furthermore, the distance d1 between the first high-frequency differential signal transmission conductor pair 2 and the distance d2 between the power circuit transmission conductor pair 3 and the distance d3 between the low-frequency differential signal transmission conductor pair 4 and the second high The distance d4 between the frequency differential signal transmission conductor pair 6 is smaller than the distance D1 between the first high frequency differential signal transmission conductor pair 2 and the power circuit transmission conductor pair 3, the power circuit transmission conductor pair 3 and the low frequency differential signal The distance D2 between the signal transmission conductor pair 4, the distance D3 between the low frequency differential signal transmission conductor pair 4 and the ground transmission conductor 5, and the distance D4 between the ground transmission conductor 5 and the second high frequency differential signal transmission conductor pair 6 . In other words, the distance d1 between the first high-frequency differential signal welding portion 211 and the second high-frequency differential signal welding portion 221, the distance d2 between the first power circuit welding portion 311 and the second power circuit welding portion 321 , The distance d3 between the first low-frequency differential signal welding portion 411 and the second low-frequency differential signal welding portion 421, and the third high-frequency differential signal welding portion 611 and the fourth high-frequency differential signal welding portion 621 The distance d4 is smaller than the distance D1 between the second high frequency differential signal welding part 221 and the first power circuit welding part 311, the distance between the second power circuit welding part 321 and the first low frequency differential signal welding part 411 The distance D2, the distance D3 between the second low-frequency differential signal welding portion 421 and the ground welding portion 51, and the distance D4 between the ground welding portion 51 and the third high-frequency differential signal welding portion 611, thereby further confirming Through the difference of the spacing d1, d2, d3, d4, D1, D2, D3, D4, the coupling stability of the paired transmission conductors is increased.

Please also refer to the third figure, which is a front perspective view of yet another preferred embodiment of the present invention, and hides the insulating colloid and sees through the elastic pieces 831a on both sides of the first shielding shell 83a to facilitate illustration. It can be clearly seen from the figure that this embodiment is similar to the above-mentioned embodiment, except that the first high-frequency differential signal transmission conductor pair 2a has a first side grounded on the side facing away from the power loop transmission conductor pair 3a. The isolation portion 71a, and the second high-frequency differential signal transmission conductor pair 6a has a second side ground isolation portion 72a on the side away from the ground transmission conductor 5a. The first side ground isolation portion 71a and the second side ground isolation portion 72a are used to conduct the ground wire of the circuit board 81a, or through the first shielding shell 83a and the ground wire of the circuit board 81a to form a connection, and the first high frequency The outer sides of the differential signal transmission conductor pair 2a and the second high-frequency differential signal transmission conductor pair 6a simultaneously form noise isolation to enhance the isolation effect of the female transmission conductor group 11a from the outside.

Please also refer to Figures 4 to 8A at the same time, which are a three-dimensional perspective view of another preferred embodiment of the present invention to a schematic diagram of the female cable line (2). It can be clearly seen from the figure that this embodiment The example is similar to the above-mentioned embodiment, except that the first high-frequency differential signal welding portion 211b, the second high-frequency differential signal welding portion 221b, the first power circuit welding portion 311b, and the second power circuit welding portion 321b, the first low-frequency differential signal welding portion 411b, the second low-frequency differential signal welding portion 421b, the ground welding portion 51b, the third high-frequency differential signal welding portion 611b, and the fourth high-frequency differential signal welding portion The surfaces of the signal soldering portion 621b are exposed (ie, the upper and lower surfaces are not sealed), so as to be soldered to a circuit board 81b by means of Surface Mount Technology (SMT), so that the present invention can utilize SMT technology Quickly connect to the circuit board 81b.

In addition, the female transmission conductor set 11b of the present invention is combined with an insulating gel 82b, and after the insulating gel 82b is combined with a first shielding shell 83b, it can be parallel, vertical or side-stationed according to the welding point and the circuit board 81b. The following different types of electrical connectors are produced in the same form. Specifically, an insertion cavity (not marked, which is the space when the electrical connector is provided for the mating of the male and female socket) is defined in the first shielding shell 83b, and the insertion direction of the insertion cavity is the same as The first high-frequency differential signal welding portion 211b, the second high-frequency differential signal welding portion 221b, the first power circuit welding portion 311b, the second power circuit welding portion 321b, the first low-frequency differential signal welding When the welding surfaces of the portion 411b, the second low-frequency differential signal welding portion 421b, the ground welding portion 51b, the third high-frequency differential signal welding portion 611b, and the fourth high-frequency differential signal welding portion 621b are parallel to each other , It can produce the sinking plate type as shown in the fifth figure A, the sinking plate type as shown in the fifth figure B, and the pad height type as shown in the fifth figure C.

And can be combined with the first high-frequency differential signal welding part 211b, the second high-frequency differential signal welding part 221b, the first power circuit welding part 311b, the second power circuit welding part 321b, the first low frequency One end of the differential signal welding portion 411b, the second low frequency differential signal welding portion 421b, the ground welding portion 51b, the third high frequency differential signal welding portion 611b, and the fourth high frequency differential signal welding portion 621b Each has at least one first bending portion 91b, and the total bending angle of the first bending portion 91b is 90 degrees. In other words, the welding point of the original female transmission conductor set 11b is parallel to the circuit board 81b, but due to the existence of the first bending portion 91b, the welding point is perpendicular to the original circuit board 81b (the first bending portion of this embodiment 91b is continuously bent with two 45-degree bending angles, so the total bending angle is 90 degrees). And by the design of the first bending portion 91b, the electrical connector can be vertically arranged on the circuit board 81b, as shown in the sixth figure.

If each of the first bending portions 91b is further away from the first high-frequency differential signal welding portion 211b, the second high-frequency differential signal welding portion 221b, the first power circuit welding portion 311b, and the second power circuit The welding portion 321b, the first low-frequency differential signal welding portion 411b, the second low-frequency differential signal welding portion 421b, the ground welding portion 51b, the third high-frequency differential signal welding portion 611b, and the fourth high-frequency One end of the differential signal welding portion 621b respectively has a second bending portion 92b, and the total bending angle of the second bending portion 92b is 90 degrees. Then change the bending direction of the first bending portion 91b to be 90 degrees horizontally, even if the welding point of the female transmission conductor set 11b is bent to the left or right by 90 degrees vertically, the second bending portion 92b is used to bend upward or downward. By bending it downward by 90 degrees, the design of the first bending portion 91b and the second bending portion 92b can make the electrical connector stand on the circuit board 81b, as shown in the seventh figure.

In addition, as shown in Figure 8A, if the first high-frequency differential signal welding portion 211b, the second high-frequency differential signal welding portion 221b, the first power circuit welding portion 311b, and the second power circuit welding 321b, the first low-frequency differential signal welding portion 411b, the second low-frequency differential signal welding portion 421b, the ground welding portion 51b, the third high-frequency differential signal welding portion 611b, and the fourth high-frequency difference The upper surface of the moving signal welding part 621b is exposed (that is, one side is sealed with glue, the other side is not sealed) for welding to a cable 85b, and a second shielding shell is provided on one side of the first shielding shell 83b The body 84b is used to cover the cable 85b. With this design, the electrical connector is made into a welding cable 85b type, and the welding part of the cable 85b is covered by the second shielding shell 84b, as shown in the eighth figure.
