Description

Technical Field

[0002] Generally, electrical connectors are used as connecting elements and accessories for electronic signals and power. Their main function is to provide electrical connections between various electronic devices or equipment to ensure accurate signal transmission. Current electrical connector structures are not only moving towards miniaturization, but also facing increasingly higher requirements for transmission speed and bandwidth. Consequently, problems arising from high-frequency signal transmission are becoming increasingly apparent. For example, if the thickness of the conductive terminals near the male connector is too large, or the width of the conductive terminals near the printed circuit board is too small, the impedance of the conductive terminals exposed to air will increase, thereby increasing energy loss during high-frequency signal transmission. Therefore, reducing energy loss during high-frequency signal transmission and improving the quality, transmission rate, and bandwidth of high-frequency signal transmission remain ongoing challenges that developers and researchers in related industries need to overcome and resolve.

[0050] Please refer to Figures 1 to 5 , Figure 1 This is a perspective view of an electrical connector structure 100 according to an embodiment of the present invention. Figure 2 This is a perspective view of the electrical connector structure 100 according to one embodiment of the present invention from another angle. Figure 3 This is a partial perspective view of an electrical connector structure 100 according to an embodiment of the present invention, omitting some conductive terminals 120. Figure 4 This is a perspective view of the conductive terminal 120 and the conductive spring piece 130 according to an embodiment of the present invention. Figure 5 This is a side view of the conductive terminal 120 and the conductive spring piece 130 according to an embodiment of the present invention. Figures 1 to 5 In the middle, the electrical connector structure 100 includes an insulating base 110, a plurality of conductive terminals 120 and a conductive spring piece 130.

[0051] In some embodiments, the insulating base 110 has a terminal slot 112 and a spring slot 114 disposed on one side of the terminal slot 112. For example, the insulating base 110 may have terminal slots 112 disposed vertically opposite each other, and the spring slot 114 of the insulating base 110 is located on the upper terminal slot 112. The terminal slot 112 of the insulating base 110 has a plurality of terminal contact areas 111. The terminal contact areas 111 of the insulating base 110 may be disposed in the upper and lower terminal slots 112, and the terminal contact areas 111 may be arranged along a first direction D1.

[0052] In some embodiments, a plurality of conductive terminals 120 are respectively inserted into a plurality of terminal contact areas 111 of the insulating base 110, and each conductive terminal 120 has a main body portion 122 and solder portions 124 and contact portions 126 disposed at opposite ends of the main body portion 122. It is worth noting that the first thickness T1 of the contact portion 126 of the conductive terminal 120 is smaller than the second thickness T2 of the main body portion 122 of the conductive terminal 120, thereby improving the signal performance and transmission speed of the electrical connector structure 100 during high-frequency transmission, and thus enabling the electrical connector structure 100 to meet the PCIe 6.0 operating standard.

[0053] Specifically, the first thickness T1 of the contact portion 126 of the conductive terminal 120 of the electrical connector structure 100 is smaller than the second thickness T2 of the main body portion 122 of the conductive terminal 120. This improves the signal performance and transmission speed of the electrical connector structure 100 during high-frequency transmission, thereby enabling the electrical connector structure 100 to meet the PCIe 6.0 operating standard. Furthermore, by adjusting the first thickness T1 of the contact portion 126 of the conductive terminal 120 and the pin width W of the solder portion 124 of the conductive terminal 120 (which will be explained in detail later), the impedance of the conductive terminal 120 exposed to air can be directly reduced, improving the impedance matching effect of the electrical connector structure 100. This, in turn, enhances the overall bandwidth performance and signal transmission quality of the electrical connector structure 100, thereby increasing its application value.

[0054] In some embodiments, each of the plurality of conductive terminals 120 may be distinguished as a signal terminal 1201 or a ground terminal 1202. Specifically, every two signal terminals 1201 are disposed adjacent to each other in the terminal slot 112, and every two ground terminals 1202 are disposed on opposite sides of the two signal terminals 1201 in the terminal slot 112. That is, the conductive terminals 120 are arranged in the order of the first direction D1: first ground terminal 1202, first signal terminal 1201, second signal terminal 1201, and second ground terminal 1202.

[0055] In some embodiments, the conductive spring element 130 is disposed in the spring slot 114 of the insulating base 110, and the conductive spring element 130 has a first portion 132 and a plurality of second portions 134 extending from the first portion 132. The plurality of second portions 134 of the conductive spring element 130 respectively contact a plurality of grounding terminals 1202, so that the plurality of grounding terminals 1202 are grounded together through the conductive spring element 130.

[0056] Next, please refer to Figures 6 to 9 , Figure 6 This is a perspective view of the conductive terminal 120 according to an embodiment of the present invention. Figure 7 This is a top view of the conductive terminal 120 according to an embodiment of the present invention. Figure 8 This is a perspective view of an electrical connector structure 100 according to an embodiment of the present invention, showing the electrical connection between a male connector 200 and a printed circuit board 300. Figure 9 This is a cross-sectional view of an electrical connector structure 100 according to an embodiment of the present invention, showing the electrical connection between a male connector 200 and a printed circuit board 300. Figures 4 to 9 In the conductive terminal 120, the first thickness T1 of the contact portion 126 is between 0.18 mm and 0.22 mm, for example, 0.2 mm, while the second thickness T2 of the main body portion 122 of the conductive terminal 120 is between 0.24 mm and 0.26 mm, for example, 0.25 mm. Furthermore, the solder portion 124 of the conductive terminal 120 has a lead width W, which is between 0.8 mm and 0.9 mm, for example, 0.86 mm. This improves the signal performance and transmission speed of the electrical connector structure 100 during high-frequency transmission, thereby enabling the electrical connector structure 100 to meet the PCIe 6.0 operating standard.

[0057] In some embodiments, the conductive terminal 120 further has a contact segment 128 located between the main body 122 and the soldering portion 124, and the second portion 134 of the conductive spring member 130 is further used to contact the contact segment 128 of the grounding terminal 1202, so that the plurality of grounding terminals 1202 are grounded together through the conductive spring member 130. Furthermore, the length direction of the conductive spring member 130 is parallel to the first direction D1, and the first portion 132 of the conductive spring member 130 is parallel to the plurality of conductive terminals 120 in the first direction D1. In some embodiments, the second portion 134 of the conductive spring member 130 extends along a second direction D2 perpendicular to the first direction D1 to contact the grounding terminal 1202. Furthermore, a plurality of conductive terminals 120 are arranged along the first direction D1 in a plurality of terminal contact areas 111 of the insulating base 110, a plurality of signal terminals 1201 do not contact the conductive spring piece 130, and two signal terminals 1201 are located between two second portions 134 of the conductive spring piece 130.

[0058] In some embodiments, the contact portion 126 of the conductive terminal 120 of the electrical connector structure 100 is electrically connected to the male connector 200, while the solder portion 124 of the conductive terminal 120 of the electrical connector structure 100 is electrically connected to the printed circuit board 300. In this way, by adjusting the first thickness T1 of the contact portion 126 of the conductive terminal 120 of the electrical connector structure 100 and the pin width W of the solder portion 124 of the conductive terminal 120, the impedance of the conductive terminal 120 exposed to air can be directly reduced, thereby improving the impedance matching effect of the electrical connector structure 100, and further enhancing the overall bandwidth performance and signal transmission quality of the electrical connector structure 100, thus increasing the application value of the electrical connector structure 100.
