[0040] In order for those skilled in the art to better understand the technical solutions of the present disclosure, the embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0042] The drawings of the embodiments of the present disclosure are used to provide further understanding of the embodiments of the present disclosure and constitute a part of the specification, which is used together with the detailed embodiments to explain the present disclosure and does not constitute a limitation of the present disclosure. The above and other features and advantages will become more apparent to those skilled in the art by referring to the detailed embodiments described below with reference to the drawings.

[0043] The present disclosure can be described with reference to plan views and / or cross-sectional views by idealized schematic illustrations of the disclosure. Thus, the example illustrations can not reflect manufacturing techniques and / or tolerances of the examples.

[0044] The embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0045] The terms used in the present disclosure are only used to describe specific embodiments and are not intended to limit the present disclosure. As used in the present disclosure, the term "and / or" includes any and all combinations of one or more of the associated listed items. As used in the present disclosure, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms "comprises," "comprising," "includes," "including," "contains," "containing," "has," "having," or the like are intended to be inclusive and allow for the presence of one or more other features, integers, steps, operations, elements, and / or groups thereof, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, and / or groups thereof.

[0046] Unless otherwise defined, all terms used in the present disclosure, including technical and scientific terms, have the same meaning as commonly understood by one of ordinary skill in the art. It will also be understood that terms such as those defined in a generally used dictionary should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and should not be interpreted in an idealized or overly formal sense unless expressly so defined in the present disclosure.

[0047] The present disclosure is not limited to the embodiments shown in the drawings, but includes modifications of the configuration formed based on the manufacturing process. Therefore, the regions illustrated in the drawings have a schematic property, and the shape of the regions shown in the drawings illustrates a specific shape of the region of the element, but is not intended to be restrictive.

[0048] FIG. 1 is a structural schematic diagram of a connector in the related art. As shown in FIG. 1, the connector includes a conductor sheet 10, an opening 20 is provided on the conductor sheet, and elastic sheets 30 with different tilt directions are provided in the opening 20. The conductor sheet 10 is stacked between the connector and the PCB board. The elastic sheet 30 can be used for electrical connection between the connector and the PCB board, and can also be used for suppressing crosstalk between adjacent pins. However, since the elastic sheet 30 is provided at the opening 20, the opening 20 forms an air cavity, and the air in the air cavity can act as a coupling medium, reducing the suppression ability of high-frequency crosstalk. Therefore, the current grounding structure is only suitable for crosstalk suppression requirements of 112 Gbps and lower rates, and cannot meet the requirements of crosstalk suppression ability of rates of 112 Gbps and above, affecting the quality of signal transmission.

[0049] In a first aspect, the embodiments of the present disclosure provide a connector for reducing signal crosstalk, thereby improving the quality of signal transmission.

[0050] Fig. 2 is a structural schematic diagram of a connector and a PCB board mating end according to an embodiment of the present disclosure, Fig. 3 is a structural schematic diagram of a connector according to an embodiment of the present disclosure, and Fig. 4 is a structural schematic diagram of a connector according to an embodiment of the present disclosure. The connector 1 and the mating end 2 are electrically connected according to the embodiments of the present disclosure.

[0051] The connector 1 comprises a housing 11, and the housing 11 comprises a connector crimping surface 111 which is electrically conductive.

[0052] In some embodiments, the housing 11 comprises a housing body made of electrically conductive material, so as to obtain an electrically conductive connector crimping surface. For example, the housing body is made of aluminum, copper or the like.

[0053] In other embodiments, the housing comprises a housing body made of insulating material and an electrically conductive layer arranged on the surface of the housing body. For example, the housing body is made of plastic, and the electrically conductive layer is arranged on the surface of the plastic housing body, so that the connector crimping surface is electrically conductive. The electrically conductive layer can be formed by using aluminum, copper or other electrically conductive metal materials.

[0054] The connector 1 comprises an elastic connecting member 3 arranged between the connector crimping surface 111 and a mating end crimping surface 21 of the mating end 2, and applies an elastic force to the connector crimping surface 111 away from the mating end 2, and applies an elastic force to the mating end crimping surface 21 away from the housing 11.

[0055] The mating end 2 can be various electronic devices, including but not limited to computers, routers and printed circuit boards. The embodiments of the present disclosure are described by taking a printed circuit board as an example. When the mating end is a printed circuit board, the mating end crimping surface of the mating end can be a crimping surface of the printed circuit board, and the potential of the crimping surface of the printed circuit board is a ground potential.

[0056] In the embodiments of the present disclosure, the connector crimping surface 111 and the mating end crimping surface 21 are both electrically conductive surfaces, and the elastic connecting member 3 is an electrically conductive connecting member. When the connector is electrically connected to the mating end, the potentials of the connector crimping surface 111, the mating end crimping surface 21 and the elastic connecting member 3 are the same, i.e., all are ground potentials.

[0057] Fig. 5 is a schematic diagram of a connector connected to a mating end according to an embodiment of the present disclosure. As shown in Fig. 5, the connector 1 further comprises a plurality of connecting units 12 arranged in an array. The embodiments of the present disclosure do not limit the number of connecting units 12 in each row and each column in the array.

[0058] In the embodiments of the present disclosure, at least one elastic connecting member 3 is arranged around each connecting unit 12.

[0059] For example, four elastic connecting pieces 3 are arranged around each connection unit 12, and the four elastic connecting pieces 3 are arranged at intervals around the connection unit 12.

[0060] FIG. 6 is a schematic diagram of a partial area of a connector according to an embodiment of the present disclosure. As shown in FIG. 6, the connection unit 12 includes a first fisheye 121 and a second fisheye 122, wherein the first fisheye 121 is used for transmitting signals, and the second fisheye 122 is used for grounding. The number of the first fisheye 121 and the second fisheye 122 in the connection unit 12 is not limited in the present disclosure. When transmitting differential signals, the connection unit 12 includes two first fisheyes 121, and the number of the second fisheye 122 can be one or two.

[0061] For example, the connection unit 12 includes two first fisheyes 121 and two second fisheyes 122, the two first fisheyes 121 are arranged at intervals, and the two second fisheyes 122 are arranged on the two sides of the first fisheye 121, respectively.

[0062] In some embodiments, the shell 11 is provided with a first through hole 113 and a second through hole 114 penetrating through the thickness of the shell 11, the first fisheye 121 penetrates through the first through hole 113 and protrudes out of the connector crimping surface 111, and the second fisheye 122 penetrates through the second through hole 114 and protrudes out of the connector crimping surface 111. The first fisheye 121 and the second fisheye 122 protrude out of the connector crimping surface 111 to facilitate electrical connection with the mating end.

[0063] In the present disclosure, the elastic connecting piece 3 can have various forms, for example, the elastic connecting piece 3 can be a spring piece, an arched spring piece, or a hair button, etc. The elastic connecting pieces 3 with different structures and the connection mode between the electric connecting piece and the mating end will be introduced one by one.

[0064] FIG. 7 is a structural schematic diagram of a spring piece according to an embodiment of the present disclosure. As shown in FIG. 7, the spring piece includes a first crimping arm 41, a second crimping arm 42, and a connecting arm 43 connecting the first crimping arm 41 and the second crimping arm 42, that is, the first crimping arm 41 and the second crimping arm 42 are arranged at the two end portions of the connecting arm 43, or can be regarded as the extension of the two end portions of the connecting arm 43.

[0065] In some embodiments, the first crimping arm 41, the second crimping arm 42, and the connecting arm 43 form a U-shaped spring piece, a V-shaped spring piece, or a Z-shaped spring piece. As shown in FIG. 7, the first crimping arm 41, the second crimping arm 42, and the connecting arm 43 form a U-shaped spring piece. When making a U-shaped spring piece, a flat plate with elasticity can be bent by 180°, and the connecting arm 43 is a smooth arc structure or a straight line structure.

[0066] Figure 8 is a structural schematic diagram of a U-shaped spring according to an embodiment of the present disclosure. As shown in Figure 8, the connecting arm 43 is a straight structure, and the first pressing arm 41, the second pressing arm 42 and the connecting arm 43 form a U-shaped spring with a right angle, i.e., the included angle between the first pressing arm 41 and the connecting arm 43 is a right angle, and the included angle between the second pressing arm 42 and the connecting arm 43 is a right angle.

[0067] Figure 9 is a structural schematic diagram of another U-shaped spring according to an embodiment of the present disclosure. As shown in Figure 9, the connecting arm 43 is a smooth arc structure, and the first pressing arm 41, the second pressing arm 42 and the connecting arm 43 form a U-shaped spring with an arc-shaped included angle, i.e., the included angle between the first pressing arm 41 and the connecting arm 43 is a smooth arc angle, and the included angle between the second pressing arm 42 and the connecting arm 43 is a smooth arc angle.

[0068] In order to ensure that the spring 4 is electrically connected to the connector 1 and the mating end 2, conductive glue is applied to the surface of the first pressing arm 41 and the second pressing arm 42 of the spring 4, i.e., conductive glue is applied to the surface of the first pressing arm 41 in contact with the connector pressing surface, and conductive glue is applied to the surface of the second pressing arm 42 in contact with the mating end pressing surface 21, as shown in Figure 10.

[0069] As shown in Figure 11, the first pressing arm 41, the second pressing arm 42 and the connecting arm 43 form a V-shaped spring. In the production of the V-shaped spring, a flat plate with elasticity can be folded in half. As shown in Figure 6, a schematic diagram of the V-shaped spring arranged around the connecting unit 12. After pressing, the V-shaped spring, the first pressing arm 41 and the second pressing arm 42 apply forces in opposite directions in the time direction to the connector 1 and the mating end 2, i.e., the first pressing arm 41 applies a force to the connector 1 in a direction away from the mating end 2, and the second pressing arm 42 applies a force to the mating end 2 in a direction away from the connector 1.

[0070] Figure 12 is a schematic diagram of the spring before and after pressing according to an embodiment of the present disclosure. As shown in Figure 12, before pressing, the ends of the first pressing arm 41 and the second pressing arm 42 are far apart, and the first pressing arm 41 only makes point or line contact with the connector 1, and the second pressing arm 42 only makes point or line contact with the mating end 2. After pressing, the ends of the first pressing arm 41 and the second pressing arm 42 are close together, and the first pressing arm 41 makes surface contact with the connector 1, i.e., the first pressing arm 41 tightly abuts the connector pressing surface, and the second pressing arm 42 makes surface contact with the mating end 2, i.e., the second pressing arm 42 tightly abuts the mating end pressing surface.

[0071] In the embodiments of the present disclosure, the U-shaped spring and the V-shaped spring can also be referred to as a hairpin-shaped spring.

[0072] As shown in FIG. 13, the first crimping arm 41, the second crimping arm 42 and the connecting arm 43 form a Z-shaped spring piece, the first crimping arm 41, the second crimping arm 42 and the connecting arm 43 are all flat plate structures, the planes where the first crimping arm 41 and the second crimping arm 42 are located are parallel to each other, and the plane where the connecting arm 43 is located is an inclined plane, that is, the plane where the connecting arm 43 is located forms a certain angle with the planes where the first crimping arm 41 and the second crimping arm 42 are located.

[0073] FIG. 14 is a schematic view of the Z-shaped spring piece provided by the embodiment of the present disclosure arranged around the connecting unit. As shown in FIG. 14, four Z-shaped spring pieces 4 are arranged around each connecting unit 12, and the four Z-shaped spring pieces 4 are arranged at intervals. It should be noted that the number of Z-shaped spring pieces can be set as required, and the embodiment of the present disclosure does not limit this.

[0074] It should be noted that the projection distance of the contact points of the Z-shaped spring piece with the connector 1 and the mating end 2 on the connector crimping surface is equal to the projection distance of the connecting arm on the connector crimping surface. That is, for the Z-shaped spring piece, the distance between the contact point with the connector 1 and the contact point with the mating end 2 is far. When transmitting high-frequency signals, especially transmitting signals of 224 Gbps (base frequency point 56 GHz, bandwidth requirement above 70 GHz), the path of the crosstalk noise of one pin coupled to the Z-shaped spring piece and reaching the mating end crimping surface is long, so the probability of the crosstalk noise coupled to the adjacent pin of the pin is large, that is, the ability to suppress crosstalk is weak. If the length of the Z-shaped spring piece is shortened, the elastic deformation ability of the Z-shaped spring piece will also be reduced, which will affect the reliability of the spring piece. However, the projection of the contact points of the U-shaped spring piece and the V-shaped spring piece with the connector 1 and the mating end 2 on the connector crimp surface is completely or basically coincident. Therefore, for the U-shaped spring piece and the V-shaped spring piece, the distance between the contact point with the connector 1 and the contact point of the mating end 2 is close, the path of the crosstalk noise of one pin coupled to the Z-shaped spring piece and arriving at the mating end crimping surface is short, and the probability of the crosstalk noise coupled to the adjacent pin of the pin is small, that is, the ability to suppress crosstalk is strong.

[0075] FIG. 15 is a structural schematic view of the structure for electrically connecting the connector and the mating end by using the spring piece in the embodiment of the present disclosure. As shown in FIG. 15, in the case of electrically connecting the connector and the mating end, the first crimping arm 41 crimps the connector crimping surface 111, and the second crimping arm 42 crimps the mating end crimping surface 21.

[0076] In some embodiments, the elastic connecting piece includes an arch-shaped spring piece. FIG. 16 is a structural schematic view of an arch-shaped spring piece and a shell provided by the embodiment of the present disclosure. As shown in FIG. 16, the arch-shaped spring piece 5 includes a base 51 and an arch-shaped portion 52, and each of the two end portions of the arch-shaped portion 52 is provided with a base 51.

[0077] A guide groove 1111 is arranged in the connector compression surface 111, the base 51 of the arc spring 5 is arranged in the guide groove 1111 and slides in the guide groove 1111, and the arch part 52 protrudes out of the guide groove 1111. When the arch part 52 is pressed, the arch part 52 is deformed, and the base 51 presses the inner wall of the guide groove 1111.

[0078] FIG. 17 is a schematic diagram of the state of the arc spring before and after being pressed by the mating end according to an embodiment of the present disclosure, wherein (a) is a schematic diagram of the state of the arc spring before being pressed, and (b) is a schematic diagram of the state of the arc spring after being pressed. As shown in FIG. 17, before the mating end 2 presses the arc spring, the arc spring 5 is in a natural state, the distance between the top end of the arch part 52 and the connector compression surface 111 is large, and the top end of the arch part 52 protrudes out of the connector compression surface 111 more. When the mating end compression surface 21 presses the arc spring 5, the arch part 52 is pressed and deformed, the distance between the top end of the arch part 52 and the connector compression surface 111 is small, and the top end of the arch part 52 protrudes out of the connector compression surface 111 less.

[0079] In some embodiments, in the width direction of the arc spring 5, the size of the base is greater than the size of the arch part.

[0080] FIG. 17 is a sectional view along the line A-A in FIG. 16. As shown in FIG. 17, the size of the base 51 of the arc spring 5 is greater than the size of the arch part 52. The width of the base 51 is less than the width of the guide groove 1111, and the height of the base 51 is not greater than the height of the guide groove 1111.

[0081] In some embodiments, the arc springs 5 can be arranged around the connection unit 12, and the number and specific arrangement of the arc springs 5 are not limited in the embodiments of the present disclosure.

[0082] For example, FIG. 18 is a schematic diagram of the layout of the arc springs according to an embodiment of the present disclosure. As shown in FIG. 18, three arc springs 5 are arranged corresponding to each connection unit 12, and at least one arc spring 5 is arranged between adjacent connection units 12.

[0083] For example, FIG. 19 is another schematic diagram of the layout of the arc springs according to an embodiment of the present disclosure. As shown in FIG. 19, two arc springs 5 are arranged corresponding to each connection unit 12, and one arc spring 5 is arranged between adjacent connection units 12.

[0084] The arc spring provided by the embodiments of the present disclosure has three contact points with the connector and the mating end, the three contact points are close to the projection of the mating end compression surface, the path that the crosstalk noise needs to pass through to reach the mating end compression surface after being coupled to the arc spring is shortened. In this way, the crosstalk noise is not easy to be coupled to the adjacent pin again, thereby improving the ability to suppress crosstalk.

[0085] In some embodiments, the resilient connector includes a fuzz button. Figure 20 is a structural schematic diagram of the fuzz button in an embodiment of this disclosure, Figure 21 is a schematic diagram before the connector and mating end are electrically connected using the fuzz button in an embodiment of this disclosure, and Figure 22 is a schematic diagram after the connector and mating end are electrically connected using the fuzz button in an embodiment of this disclosure. Referring to Figures 20, 21, and 22, the fuzz button includes spirally arranged filaments, which are spirally wound with different curvatures at different points. When a force is applied to the radial direction of the fuzz button, its radial dimension will change.

[0086] In use, the button 6 can be placed on the connector 1 first. At this time, the button 6 is in its natural state. When opposing forces are applied to the connector 1 and the mating end 2, the button is deformed by the compression of the connector 1 and the mating end 2, and then opposing forces are applied to the connector 1 and the mating end 2. That is, the button 6 applies a force to the connector 1 that is opposite to the mating end 2, and applies a force to the mating end 2 that is opposite to the connector 1.

[0087] The outer surface of the button 6 is not smooth. When the connector is electrically connected to the mating end, there are multiple contact points between the button and both the connector crimping surface and the mating surface. Moreover, the distance between adjacent contact points is relatively short, which shortens the path that crosstalk noise coupled to the button needs to take to reach the mating surface. Therefore, crosstalk noise is less likely to be recoupled to adjacent pins, thereby improving the ability to suppress crosstalk.

[0088] Figure 23 is a schematic diagram of one layout of the bobby button in an embodiment of this disclosure. As shown in Figure 23, the bobby button 6 has a ring structure, and a ring-shaped bobby button is arranged around each connecting unit 12.

[0089] Figure 24 is a schematic diagram of another layout of the bobby button in an embodiment of this disclosure. As shown in Figure 24, the bobby button 6 has a linear structure and is disposed between adjacent rows of the connecting unit 12.

[0090] To facilitate the installation and positioning of the button 6, a positioning groove or positioning protrusion is provided on the connector crimping surface 111, and the button is fixed in the positioning groove or at the top of the positioning protrusion.

[0091] Figure 25 illustrates one arrangement of the button in an embodiment of this disclosure. As shown in Figure 25, a positioning groove 1112 is provided on the connector crimping surface 111, and the button 6 is disposed within the positioning groove 1112. To improve the reliability of the electrical connection between the connector 1 and the mating end, a conductive medium 1113 can also be provided within the positioning groove 1112. The button 6 is electrically connected to the conductive medium 1113, and the conductive medium 1113 is electrically connected to the connector crimping surface 111, thereby making the potentials of the connector crimping surface 111, the button 6, and the mating surface of the mating end the same, i.e., in a grounded state.

[0092] Figure 26 shows another layout of the bobby button in an embodiment of this disclosure. As shown in Figure 26, a positioning protrusion 1114 is provided in the positioning groove 1112, and the bobby button 6 is positioned on the top of the positioning protrusion 1114.

[0093] Figure 27 shows the simulated crosstalk curves of the spring sheet provided in this embodiment and an existing perforated spring sheet. The horizontal axis represents the crosstalk noise frequency (GHz), and the vertical axis represents the crosstalk (dB). The solid line represents the simulated crosstalk curve of the perforated spring sheet, and the dashed line represents the simulated crosstalk curve of the spring sheet provided in this embodiment. As can be seen from Figure 27, the crosstalk of the spring sheet provided in this embodiment is significantly reduced.

[0094] Figure 28 shows the simulated crosstalk curves of the U-shaped and Z-shaped springs provided in the embodiments of this disclosure. The horizontal axis represents the crosstalk noise frequency (GHz), and the vertical axis represents the crosstalk (dB). The solid line represents the simulated crosstalk curve of the Z-shaped spring provided in this embodiment, and the dashed lines represent the simulated crosstalk curves of the U-shaped and V-shaped springs provided in this embodiment. As can be seen from Figure 28, the crosstalk of the U-shaped and V-shaped springs provided in the embodiments of this disclosure is significantly lower than that of the Z-shaped spring. This is because the distance between the two contact points of the Z-shaped spring is longer. When transmitting high-frequency signals, especially 224Gbps (base frequency 56GHz, bandwidth requirement above 70GHz), the crosstalk noise of one pin needs to travel a longer path to couple to the spring and reach the ground plane of the PCB board. Therefore, the probability of this crosstalk coupling to adjacent pins is higher.

[0095] Figure 29 shows the simulated crosstalk curves of the U-shaped spring, Z-shaped spring, and arched spring provided in the embodiments of this disclosure. The horizontal axis represents the crosstalk noise frequency (GHz), and the vertical axis represents crosstalk (dB). The solid line represents the simulated crosstalk curve of the Z-shaped spring provided in this embodiment, the dashed line represents the simulated crosstalk curve of the U-shaped spring provided in this embodiment, and the dotted line represents the simulated crosstalk curve of the arched spring provided in this embodiment. As can be seen from Figure 29, the arched spring has the strongest crosstalk resistance, followed by the U-shaped spring, while the Z-shaped spring has a relatively weaker crosstalk resistance. However, the crosstalk resistance of the Z-shaped spring is still superior to that of the open-hole type in the prior art.

[0096] Figure 30 shows the simulated crosstalk curves of the Z-shaped spring provided in this embodiment with and without an opening and a shielding mesh. The horizontal axis represents the crosstalk noise frequency (GHz), and the vertical axis represents crosstalk (dB). The solid line represents the simulated crosstalk curve of the Z-shaped spring with and without an opening and a shielding mesh, while the dashed line represents the simulated crosstalk curve of the Z-shaped spring without an opening. As can be seen from Figure 30, when the distance between the crimping surface and the opposite crimping surface of the connector is the same, if an opening (air hole) is provided around the Z-shaped spring, the ability to suppress crosstalk decreases as the crosstalk noise frequency increases, and the overall crosstalk suppression ability is lower than that of the Z-shaped spring without an opening.

[0097] The connectors provided in this disclosure are suitable for high-speed connectors, and are particularly suitable for high-speed backplane connectors and high-speed snap-on connectors that connect to PCBs.

[0098] Secondly, embodiments of this disclosure provide an electronic device.

[0099] Figure 31 is a schematic diagram of the structure of an electronic device provided in an embodiment of this disclosure. As shown in Figure 31, the electronic device includes a connector 1 and a mating end 2, which are electrically connected. The connector 1 includes the connector provided in the embodiment of this disclosure, which will not be described in detail here.

[0100] In this embodiment of the disclosure, the interface can be a computer, router, printed circuit board, or other components, and the disclosure does not limit the form of the interface.

[0101] The electronic device provided in this embodiment has a connector crimping surface on the housing of the connector, and an elastic connector is disposed between the connector crimping surface and the mating surface. An elastic force is applied to the connector crimping surface away from the mating end, and an elastic force is applied to the mating surface away from the housing. Moreover, both the connector crimping surface and the mating surface are conductive surfaces, and the elastic connector is a conductive connector. Electrical connection between the connector and the mating end can be achieved without openings in the housing, and crosstalk of signals can be reduced, thereby improving the signal transmission quality of the electronic device.

[0102] This disclosure has disclosed exemplary embodiments, and although specific terminology has been used, it is for general illustrative purposes only and should not be construed as limiting. In some instances, it will be apparent to those skilled in the art that features, characteristics, and / or elements described in conjunction with particular embodiments may be used alone, or in combination with features, characteristics, and / or elements described in conjunction with other embodiments, unless otherwise expressly indicated.
