Description

Technical Field

[0001] The invention relates to the field of connectors, and in particular to a connector for improving crosstalk interference. Background Art

[0002] Connectors play a vital role in existing electronic devices and communication systems. They not only need to ensure the stability of physical connections, but also ensure that electrical signals can be transmitted efficiently and accurately. However, in the field of high-frequency signal transmission, traditional connector design faces a series of challenges.

[0003] Reference Figure 1 and attached Figure 2 As shown in FIG. 1 , it is a schematic diagram of the structure of the existing connector 1 and a schematic diagram of the exploded structure. It can be seen that the upper terminal group 11 is embedded in the upper tongue plate 111, and the lower terminal group 12 is embedded in the lower tongue plate 121. Figure 2 As shown in the figure, it can be clearly seen that the two sides of the grounding plate 13 extend and are connected to the upper terminal group 11 and the lower terminal group 12 respectively, so the upper terminal group 11 and the lower terminal group 12 are mutually conductive through the grounding plate. The main problem is that when an integrated conductive loop is formed, although the structure can be simplified and the mechanical strength can be improved, this also leads to a relative increase in the impedance path of the entire connector system. This increased impedance may not be a problem for low-frequency or DC applications, but it will have a significant impact on high-frequency signals.

[0004] Specifically, due to the crosstalk interference caused by the non-ideal grounding design.

[0029] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations. The basic principles defined in the following description of the present invention can be applied to other embodiments, variations, improvements, equivalent solutions, and other technical solutions without departing from the spirit and scope of the present invention.

[0030] Those skilled in the art should understand that in the disclosure of the present invention, the orientation or positional relationship indicated by terms such as "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present invention.

[0031] It can be understood that the term "a" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of the element can be multiple. The term "a" should not be construed as limiting the quantity.

[0032] Refer to the Figure 3 to the Figure 8 figures. The connector 6 for improving crosstalk interference according to the embodiment of the present invention is schematically shown. As Figure 3 shown, it is a schematic diagram of the overall structure of the connector 6 for improving crosstalk interference. The connector 6 for improving crosstalk interference includes a fixing component 61, a first grounding terminal group 62, a second grounding terminal group 63, a first grounding piece 65, and a second grounding piece 64. The first grounding terminal group 62 is connected to the first grounding piece 65 and forms an independent electrical conduction loop. The second grounding terminal group 63 is connected to the second grounding piece 64 and forms another independent electrical conduction loop. The first grounding terminal group 62 and the second grounding terminal group 63 are fixed to the fixing component 61, and the first grounding piece 65 and the second grounding piece 64 are kept at a predetermined interval. Keeping the first grounding piece 65 and the second grounding piece 64 at an interval can effectively reduce crosstalk interference during signal transmission, significantly improve the signal quality during high-frequency signal transmission, and the first grounding piece 65 and the second grounding piece 64 are not connected, further reducing the overall impedance of the connector, which helps to reduce signal attenuation during high-frequency signal transmission and improve signal transmission quality.

[0033] Specifically, the first grounding terminal group 62 includes a plurality of first grounding terminals 621. In other words, the plurality of first grounding terminals 621 together form the first grounding terminal group 62. The second grounding terminal group 63 includes a plurality of second grounding terminals 631. Similarly, the plurality of second grounding terminals 631 together form the second grounding terminal group 63. Preferably, in the present invention, the number of the first grounding terminals 621 and the second grounding terminals 631 is implemented as 4. Those skilled in the art should understand that the implemented number of the first grounding terminals 621 and the second grounding terminals 631 can also be other numbers, including but not limited to the numbers listed above.

[0034] The connector 6 for improving crosstalk interference further includes a plurality of first connection terminals 651 and a plurality of second connection terminals 641. Preferably, in this embodiment, the number of the first connection terminals 651 and the second connection terminals 641 is implemented as 4. Those skilled in the art should understand that the implemented number of the first connection terminals 651 and the second connection terminals 641 can also be other numbers, including but not limited to the numbers listed above.

[0035] The first connection terminals 651 are integrally provided on one side of the first grounding plate 65, and the other sides are respectively connected to the first grounding terminals 621 of the first grounding terminal group 62. The second connection terminals 641 are integrally provided on one side of the second grounding plate 64, and the other sides are respectively connected to the second grounding terminals 631 of the second grounding terminal group 63, and the first connection terminals 651 and the second connection terminals 641 are arranged back to back. That is to say, the extending directions of the first connection terminals 651 and the second connection terminals 641 are opposite to each other, so that the sides of the first grounding plate 65 and the second grounding plate 64 with flat edges are arranged opposite to each other, and a spaced space 66 is formed between the sides of the first grounding plate 65 and the second grounding plate 64 with flat edges.

[0036] The first connection terminals 651 and the first grounding plate 65 are integrally manufactured and formed to ensure the integrity of the connection between the first connection terminals 651 and the first grounding plate 65, thereby further reducing the impedance during connection and reducing the signal attenuation during signal transmission; the second connection terminals 641 and the second grounding plate 64 are also integrally stamped and bent to ensure the integrity of the connection between the second connection terminals 641 and the second grounding plate 64, while reducing the impedance, further reducing the production cost and saving the material cost for connecting the first connection terminals 651 and the second connection terminals 641 to the first grounding plate 65 and the second grounding plate 64.

[0037] Refer to the appendix Figure 4As shown, the spacing space 66 can enhance electrical insulation and reduce mutual interference between electromagnetic signals, which is crucial for maintaining signal integrity and improving the quality of data transmission. Further, the spacing space 66 can effectively divide the current path, thereby reducing the overall impedance of the connector and reducing attenuation and distortion of high-frequency signals during transmission.

[0038] Refer to the attached Figure 5 to the attached Figure 7 As shown, the fixing component 61 includes an upper tongue piece 611, a lower tongue piece 612, and a base 613. The upper tongue piece 611 and the lower tongue piece 612 are installed on both sides of the base 613. Further, the base 613 includes an upper base 6131 and a lower base 6132. The upper base 6131 has a plurality of first mounting holes 6141, and the lower base 6132 has a plurality of second mounting holes 6142. The upper base 6131 and the lower base 6132 can be engaged with each other to form an integral structure. The first mounting holes 6141 and the second mounting holes 6142 are evenly spaced on both sides of the base 613.

[0039] The upper tongue piece 611 has a plurality of first positioning grooves 6111, and the lower tongue piece 612 has a plurality of second positioning grooves 6121. The first positioning grooves 6111 correspond to the first mounting holes 6141, and the second positioning grooves 6121 correspond to the second mounting holes 6142. A plurality of the first positioning grooves 6111 and the second positioning grooves 6121 are both spaced on the upper tongue piece 611 and the lower tongue piece 612 to ensure electrical insulation between the grooves.

[0040] The upper tongue piece 611 further includes a plurality of first contact terminals 6112. The first contact terminals 6112 are spaced and installed and fitted with the first grounding terminals 621 in the first positioning grooves 6111 and pass through the first mounting holes 6141 to ensure the stability of the installation, so that the first contact terminals 6112 and the first grounding terminals 621 can be fixed on the upper tongue piece 611, and the first grounding piece 65 fits the lower bottom surface of the base 613; the lower tongue piece further includes a plurality of second contact terminals 6122. The second contact terminals 6122 are spaced and installed and fitted with the second grounding terminals 631 in the second positioning grooves 6121 and pass through the second mounting holes 6142 to ensure the stability of the installation, so that the second contact terminals 6122 and the second grounding terminals 631 can be fixed on the lower tongue piece 612, and the second grounding piece 64 fits the lower bottom surface of the base 613. As Figure 7As shown, the sides of the first ground plate 65 and the second ground plate 64 with flat edges are arranged opposite to each other, and the spacing space 66 is formed between the sides of the first ground plate 65 and the second ground plate 64 with flat edges. The spacing space 66 can enhance electrical insulation and reduce mutual interference between electromagnetic signals, which is crucial for maintaining signal integrity and improving the quality of data transmission. Further, the spacing space 66 can effectively divide the current path, thereby reducing the overall impedance of the connector, and reducing attenuation and distortion of high-frequency signals during transmission.

[0041] The fixing component 61 further includes a bottom plate 617, which is installed below the base 613, that is, below the position where the upper base 6131 engages with the lower base 6132, so as to clamp the first ground plate 65 and the second ground plate 64, and form the spacing space 66 between the first ground plate 65 and the second ground plate 64. Further strengthen the overall structural strength of the connector 6 for improving crosstalk interference and maintain the stability of electrical insulation.

[0042] The fixing component 61 further includes a fixing plate 615 and a reinforcing plate 616. The fixing plate 615 is attached to the surface of the upper tongue 611, that is, the side without the first positioning groove 6111. The reinforcing plate 616 is attached to the surface of the lower tongue 612, that is, the side without the second positioning groove 6121. The fixing plate 615 and the reinforcing plate 616 are made of high-strength materials to further strengthen the interface strength of the connector 6 for improving crosstalk interference. At the same time, a fixing groove 6151 is provided on the fixing plate 615 for fixedly connecting the connector of the connector 6 for improving crosstalk interference, ensuring the stability of the connector 6 for improving crosstalk interference during signal transmission.

[0043] Reference Figure 8 As shown, it is a schematic diagram of parameter signal testing of the connector 6 for improving crosstalk interference and the existing connector 1. As shown in the figure, the horizontal axis represents frequency and the vertical axis represents dB value. Under the same parameter test, the attenuation value of the connector 6 for improving crosstalk interference is less than -40 dB when the high-frequency signal is between 35 GHz and 45 GHz. For the existing connector 1 under the same high-frequency signal test, when the high-frequency signal is between 35 GHz and 45 GHz, its attenuation value exceeds -40 dB and even approaches -50 dB. It can be seen that the connector 6 for improving crosstalk interference achieves a lower signal attenuation degree than the existing connector 1 in the high-frequency range. That is to say, the connector 6 for improving crosstalk interference helps to reduce signal attenuation during high-frequency signal transmission, improve signal transmission quality, meet the requirements of high-speed data transmission technologies such as PAM4 and PCIe 5.0, and adapt to the needs of the high-speed connector era.
