[0044] The accompanying drawings of the embodiments of the present disclosure are used to provide a further understanding of the embodiments of the present disclosure, and constitute a part of the specification, and are used together with the detailed embodiments to explain the present disclosure, and do not constitute a limitation of the present disclosure. By describing the detailed embodiments with reference to the accompanying drawings, the above and other features and advantages will become more apparent to those skilled in the art.

[0045] The present disclosure may be described with reference to plan views and / or cross-sectional views by means of ideal schematic views of the present disclosure. Therefore, the exemplary illustrations may be modified according to manufacturing techniques and / or tolerances.

[0046] In the absence of conflict, the various embodiments of the present disclosure and the various features therein may be combined with each other.

[0047] The terms used in the present disclosure are only used to describe specific embodiments and are not intended to limit the present disclosure.

It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and this disclosure, and will not be interpreted as having an idealized or overly formal meaning unless expressly defined in this disclosure.

[0049] The present disclosure is not limited to the embodiments shown in the drawings, but includes modifications of the configurations formed based on the manufacturing process. Therefore, the regions illustrated in the drawings have schematic properties, and the shapes of the regions shown in the drawings illustrate the specific shapes of the regions of the elements, but are not intended to be limiting.

[0050] Figure 1It is a structural diagram of a connector in the related art, such as Figure 1 As shown, the connector includes a conductor sheet 10, an opening 20 is arranged on the conductor sheet, and springs 30 with different inclination directions are arranged in the opening 20, and then the conductor sheet 10 is stacked between the connector and the PCB board, and the springs 30 are used for both electrical connection between the connector and the PCB board and for suppressing crosstalk between adjacent pins. However, since the springs 30 are arranged at the opening 20, the opening 20 forms an air cavity, and the air in the air cavity can be used as a coupling medium, which reduces the ability to suppress high-frequency crosstalk. Therefore, the current grounding structure is only suitable for the crosstalk suppression requirements of 112Gbps and lower rates, and cannot meet the requirements of crosstalk suppression capabilities at rates above 112Gbps, affecting the quality of signal transmission.

[0051] In a first aspect, an embodiment of the present disclosure provides a connector for reducing signal crosstalk, thereby improving signal transmission quality.

[0052] Figure 2 A schematic diagram of the structure of a connector and a PCB board docking end is provided for an embodiment of the present disclosure. Figure 3 A partial structural diagram of a connector is provided in accordance with an embodiment of the present disclosure. Figure 4 A partial structural diagram of a connector is provided in accordance with an embodiment of the present disclosure. Figure 2 , Figure 3 and Figure 4 The connector 1 provided in the embodiment of the present disclosure is electrically connected to the docking terminal 2, and the connector 1 includes:

[0053] The housing 11 includes a connector crimping surface 111 , and the connector crimping surface 111 is conductive.

[0054] In some embodiments, the housing 11 includes a conductive housing body to obtain a conductive connector crimping surface. For example, the housing body is made of conductive materials such as aluminum and copper.

[0055] In other embodiments, the housing includes an insulating housing body and a conductive layer disposed on the surface of the insulating housing body. For example, the housing body is made of plastic, and the conductive layer is disposed on the surface of the plastic housing body, so that the connector crimping surface is conductive. The conductive layer can be formed of conductive metal materials such as aluminum and copper.

[0056] The elastic connector 3 is arranged between the connector crimping surface 111 and the opposite crimping surface 21 of the butt end 2, and applies an elastic force to the connector crimping surface 111 away from the butt end 2, and applies an elastic force to the opposite crimping surface 21 away from the shell 11.

[0057] The docking terminal 2 may 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 docking terminal is a printed circuit board, the docking terminal crimping surface of the docking terminal may be a crimping surface of the printed circuit board, and the potential of the crimping surface of the printed circuit board is the ground potential.

[0058] In the embodiment of the present disclosure, the connector crimping surface 111 and the opposite end crimping surface 21 are both conductive surfaces, and the elastic connector 3 is a conductive connector. When the connector is electrically connected to the opposite end, the connector crimping surface 111, the opposite end crimping surface 21 and the elastic connector 3 have the same potential, that is, they are all ground potential.

[0059] Figure 5 A schematic diagram of a connector and a docking end connected to each other provided by an embodiment of the present disclosure. Figure 5 As shown, the connector 1 further includes a plurality of connection units 12 arranged in an array. The embodiment of the present disclosure does not limit the number of connection units 12 in each row and column in the array.

[0060] In the embodiment of the present disclosure, at least one elastic connector 3 is correspondingly disposed for each connection unit 12 , and the at least one elastic connector 3 is disposed at intervals around the connection unit 12 .

[0061] For example, four elastic connectors 3 are arranged around each connecting unit 12 , and the four elastic connectors 3 are arranged at intervals around the connecting unit 12 .

[0062] Figure 6 A schematic diagram of a local area of ​​a connector provided by an embodiment of the present disclosure. Figure 6 As shown, the connection unit 12 includes a first fisheye 121 and a second fisheye 122, wherein the first fisheye 121 is used to transmit signals, and the second fisheye 122 is used for grounding. The embodiment of the present disclosure does not limit the number of the first fisheye 121 and the second fisheye 122 in the connection unit 12. When transmitting a differential signal, the connection unit 12 includes two first fisheyes 121, and the number of the second fisheye 122 can be one or two.

[0063] By way of 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 both sides of the first fisheye 121 .

[0064] In some embodiments, the housing 11 is provided with a first through hole 113 and a second through hole 114 that penetrates the thickness thereof, the first fish eye 121 passes through the first through hole 113 and protrudes out of the connector crimping surface 111, and the second fish eye 122 passes through the second through hole 114 and protrudes out of the connector crimping surface 111. The first fish eye 121 and the second fish eye 122 protrude out of the connector crimping surface 111 to facilitate electrical connection with the butt end.

[0065] In the embodiment of the present disclosure, the elastic connector 3 can have various forms, for example, the elastic connector 3 can be a spring sheet, an arched spring sheet or a fur button, etc. The following introduces the elastic connector 3 of different structures and the way of connecting the electrical connector and the docking end one by one.

[0066] Figure 7 The schematic diagram of the structure of a spring provided by the embodiment of the present disclosure is shown in FIG. Figure 7 As shown, 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 two ends of the connecting arm 43, and can also be regarded as extensions of the two ends of the connecting arm 43.

[0067] In some embodiments, the first crimping arm 41, the second crimping arm 42 and the connecting arm 43 form a U-shaped spring sheet, a V-shaped spring sheet or a Z-shaped spring sheet. Figure 7 As shown, the first crimping arm 41, the second crimping arm 42 and the connecting arm 43 form a U-shaped spring piece. When making the U-shaped spring piece, the elastic flat plate can be bent 180 degrees, and the connecting arm 43 is a smooth arc structure or a straight line structure.

[0068] Figure 8 The structure diagram of a U-shaped spring piece provided by an embodiment of the present disclosure is shown in FIG. Figure 8 As shown, the connecting arm 43 is a straight structure, and the first crimping arm 41, the second crimping arm 42 and the connecting arm 43 form a right-angled U-shaped spring piece, that is, the angle between the first crimping arm 41 and the connecting arm 43 is a vertical angle, and the angle between the second crimping arm 42 and the connecting arm 43 is a vertical angle.

[0069] Fig. 9 This is a schematic diagram of the structure of another U-shaped spring provided in an embodiment of the present disclosure. Fig. 9 As shown, the connecting arm 43 is a smooth arc structure, and the first crimping arm 41, the second crimping arm 42 and the connecting arm 43 form a U-shaped spring piece with an arc angle, that is, the angle between the first crimping arm 41 and the connecting arm 43 is a smoothly transitioned arc angle, and the angle between the second crimping arm 42 and the connecting arm 43 is a smoothly transitioned arc angle.

[0070] In order to ensure that the spring piece 4 is electrically connected to the connector 1 and the butt end 2, conductive glue is applied to the surfaces of the first crimping arm 41 and the second crimping arm 42 of the spring piece 4, that is, conductive glue is applied to the surface of the first crimping arm 41 that contacts the crimping surface of the connector, and conductive glue is applied to the surface of the second crimping arm 42 that contacts the crimping surface 21 of the opposite end. Fig.10 shown.

[0071] like Fig.11 As shown, the first crimping arm 41, the second crimping arm 42 and the connecting arm 43 form a V-shaped spring sheet. When making the V-shaped spring sheet, the elastic flat plate can be folded in half. Figure 6 FIG. 1 is a schematic diagram of arranging the V-shaped spring piece around the connection unit 12. After the V-shaped spring piece is crimped, the first crimping arm 41 and the second crimping arm 42 exert forces in opposite directions on the connector 1 and the butt end 2, that is, exerting a force on the connector 1 facing away from the butt end 2, and exerting a force on the butt end 2 facing away from the connector 1.

[0072] Fig.12 Schematic diagram of the spring piece before and after crimping in the embodiment of the present disclosure. Fig.12 Before crimping, the V-shaped spring piece has a long distance between the ends of the first crimping arm 41 and the second crimping arm 42, and the first crimping arm 41 is only in point contact or line contact with the connector 1, and the second crimping arm 42 is only in point contact or line contact with the butt end 2. After crimping, the ends of the first crimping arm 41 and the second crimping arm 42 are close to each other, and the first crimping arm 41 is in surface contact with the connector 1, that is, the first crimping arm 41 is close to the crimping surface of the connector; the second crimping arm 42 is in surface contact with the butt end 2, that is, the second crimping arm 42 is close to the crimping surface of the opposite end.

[0073] In the disclosed embodiment, the U-shaped spring clip and the V-shaped spring clip may also be referred to as a hairpin-type spring clip.

[0074] like Fig.13 As shown, 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 surface where the connecting arm 43 is located is an inclined surface, that is, the plane where the connecting arm 43 is located is at a certain angle to the planes where the first crimping arm 41 and the second crimping arm 42 are located.

[0075] Fig.14 This is a schematic diagram of arranging the Z-shaped spring sheet provided in the embodiment of the present disclosure around the connection unit. Fig.14 As shown, four Z-shaped spring pieces 4 are arranged around each connection 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.

[0076] It should be noted that the projection distance of the contact points of the Z-shaped spring with connector 1 and butt 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, the distance between the contact point with connector 1 and the contact point with butt end 2 is relatively far. When transmitting high-frequency signals, especially 224Gbps (base frequency 56GHz, bandwidth requirement above 70GHz) signals, the path for the crosstalk noise of a pin to couple to the Z-shaped spring and reach the crimping surface of the butt end is relatively long. Therefore, the probability of the crosstalk noise coupling to the pin adjacent to the pin is relatively high, that is, the ability to suppress crosstalk is relatively weak. If the length of the Z-shaped spring is shortened, the elastic deformation ability of the Z-shaped spring will be reduced, affecting the reliability of the spring. However, the projections of the contact points of the U-shaped spring clip and the V-shaped spring clip with the connector 1 and the butt end 2 on the connector crimping surface completely or substantially overlap. Therefore, for the U-shaped spring clip and the V-shaped spring clip, the distances between the contact points with the connector 1 and the contact points with the butt end 2 are relatively close, and the path for the crosstalk noise of one pin to couple to the Z-shaped spring clip and reach the crimping surface of the butt end is relatively short. The probability of the crosstalk noise coupling to the pins adjacent to the pin is relatively small, that is, the ability to suppress crosstalk is relatively strong.

[0077] Fig.15 FIG. 1 is a schematic diagram of a structure in which a connector and a butt end are electrically connected by using a spring in an embodiment of the present disclosure. Fig.15 As shown, when the connector is electrically connected to 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 .

[0078] In some embodiments, the elastic connecting member includes an arched spring piece. Fig.16 The schematic diagram of the structure of an arched spring and a housing provided in an embodiment of the present disclosure. Fig.16 As shown, the arched spring piece 5 includes a base 51 and an arched portion 52 , and a base 51 is disposed at each of the two ends of the arched portion 52 .

[0079] A guide groove 1111 is provided in the connector crimping surface 111, and the base 51 of the arch spring 5 is provided in the guide groove 1111 and slides in the guide groove 1111, and the arch portion 52 protrudes out of the guide groove 1111. When the arch portion 52 is squeezed, the arch portion 52 is deformed, and the base 51 squeezes the inner wall of the guide groove 1111.

[0080] Fig.17 The following is a schematic diagram of an arched spring piece before and after being squeezed by a butt end according to an embodiment of the present disclosure, wherein (a) is a schematic diagram of the arched spring piece before being squeezed, and (b) is a schematic diagram of the arched spring piece after being squeezed. Fig.17As shown, before the butt end 2 squeezes the arched spring piece, the arched spring piece 5 is in a natural state, the top of the arched portion 52 is at a greater distance from the crimping surface 111 of the connecting portion, and the top of the arched portion 52 protrudes more from the connector crimping surface 111. When the butt end crimping surface 21 squeezes the arched spring piece 5, the arched portion 52 is squeezed and deformed, the top of the arched portion 52 is at a smaller distance from the crimping surface 111 of the connecting portion, and the top of the arched portion 52 protrudes less from the connector crimping surface 111.

[0081] In some embodiments, in the width direction of the arched elastic piece 5 , the size of the base portion is greater than the size of the arched portion.

[0082] Fig.17 For along Fig.16 The cross-sectional view of the AA line. Fig.17 As shown, the size of the base 51 of the arched elastic sheet 5 is larger than the size of the arched portion 52. The width of the base 51 is smaller than the width of the guide slot 1111, and the height of the base 51 is not greater than the height of the guide slot 1111.

[0083] In some embodiments, the arched spring pieces 5 may be arranged around the connecting unit 12 . The embodiment of the present disclosure does not limit the number and specific arrangement of the arched spring pieces 5 .

[0084] For example, Fig.18 FIG. 1 is a schematic diagram of a layout of the arched springs in the embodiment of the present disclosure. Fig.18 As shown, three arched elastic pieces 5 are correspondingly arranged at each connection unit 12 , and at least one arched elastic piece 5 is arranged between adjacent connection units 12 .

[0085] For example, Fig.19 FIG. 2 is another schematic diagram of the layout of the arched spring piece in the embodiment of the present disclosure. Fig.19 As shown, two arched elastic sheets 5 are correspondingly arranged at each connection unit 12 , and one arched elastic sheet 5 is arranged between adjacent connection units 12 .

[0086] The arch spring piece provided in the embodiment of the present disclosure has three contact points with the connector and the butt end. The projection distance of the three contact points on the crimping surface of the opposite end is relatively close, which shortens the path that the crosstalk noise coupled to the arch spring piece needs to travel to reach the crimping surface of the opposite end. In this way, the crosstalk noise is not easily coupled to the adjacent pins for a second time, thereby improving the ability to suppress crosstalk.

[0087] In some embodiments, the elastic connector comprises a wool button. Fig. 20 is a schematic diagram of the structure of the wool button in the embodiment of the present disclosure, Fig.21 This is a schematic diagram of an embodiment of the present disclosure before the connector and the butt end are electrically connected using a wool button. Fig. 22 FIG. 1 is a schematic diagram of an embodiment of the present disclosure in which a connector and a butt end are electrically connected using a wool button. Fig. 20 , Fig.21 and Fig. 22 The wool button includes spirally arranged filaments, the filaments are spirally wound, and the curvatures of different sections are different. When a force is applied in the radial direction of the wool button, the radial size of the wool button will change.

[0088] When in use, the fur button 6 can be first placed on the connector 1, and the fur button 6 is in a natural state. When forces acting in opposite directions are applied to the connector 1 and the butt end 2, the fur button is squeezed by the connector 1 and the butt end 2, deforms, and applies forces in opposite directions to the connector 1 and the butt end 2, that is, the fur button 6 applies forces acting in the direction away from the butt end 2 to the connector 1, and applies forces acting in the direction away from the connector 1 to the butt end 2.

[0089] The outer surface of the fur button 6 is not smooth. When the connector is electrically connected to the mating end, there are multiple contact points between the fur button and the crimping surface of the connector and the crimping surface of the opposite end, and the distance between adjacent contact points is relatively close, which shortens the path that the crosstalk noise coupled to the fur button needs to take to reach the crimping surface of the opposite end. Therefore, the crosstalk noise is not easily coupled to the adjacent pins for a second time, thereby improving the ability to suppress crosstalk.

[0090] Fig.23 FIG. 1 is a schematic diagram of a layout of the fur buttons in the embodiment of the present disclosure. Fig.23 As shown, the wool button 6 is an annular structure, and an annular wool button is arranged around each connecting unit 12 .

[0091] Fig.24 FIG. 2 is another schematic diagram of the layout of the fur buttons in the embodiment of the present disclosure. Fig.24 As shown, the wool buttons 6 are linear structures, and the wool buttons 6 are arranged between adjacent rows of the connecting units 12 .

[0092] In order to facilitate the installation and positioning of the wool button 6, a positioning groove or a positioning protrusion is provided on the connector crimping surface 111, and the wool button is fixed in the positioning groove or at the top of the positioning protrusion.

[0093] Fig.25 This is a layout of the fur buttons in the embodiment of the present disclosure. Fig.25 As shown, a positioning groove 1112 is provided on the connector crimping surface 111, and the hair button 6 is provided in the positioning groove 1112. In order to improve the reliability of the electrical connection between the connector 1 and the butt end, a conductive medium 1113 can also be provided in the positioning groove 1112, the hair button 6 is electrically connected to the conductive medium 1113, and the conductive medium 1113 is electrically connected to the connector crimping surface 111, so that the potentials of the connector crimping surface 111, the hair button 6 and the crimping surface of the opposite end are the same, that is, they are in a grounded state.

[0094] Fig.26This is another layout of the fur buttons in the embodiment of the present disclosure. Fig.26 As shown, a positioning protrusion 1114 is provided in the positioning groove 1112 , and the wool button 6 is arranged on the top of the positioning protrusion 1114 .

[0095] Fig. 27 The simulated crosstalk curve of the spring sheet provided in the embodiment of the present disclosure and the existing spring sheet with a hole is shown in the figure, wherein the horizontal axis is the crosstalk noise frequency (GHz), the vertical axis is the crosstalk (dB), the solid line represents the simulated crosstalk curve of the spring sheet with a hole, and the dotted line represents the simulated crosstalk curve of the spring sheet provided in the embodiment. Fig. 27 It can be seen that the crosstalk of the spring provided by the embodiment of the present disclosure is significantly reduced.

[0096] Fig.28 The simulated crosstalk curve of the U-shaped spring and the Z-shaped spring provided in the embodiment of the present disclosure is shown in the figure, wherein the horizontal axis is the crosstalk noise frequency (GHz), the vertical axis is the crosstalk (dB), the solid line represents the simulated crosstalk curve of the Z-shaped spring provided in the embodiment, and the dotted line represents the simulated crosstalk curve of the U-shaped and V-shaped springs provided in the embodiment. Fig.28 It can be seen that the U-shaped spring clip and the V-shaped spring clip provided in the embodiments of the present disclosure have significantly lower crosstalk than the Z-shaped spring clip. This is because the distance between the two contact points of the Z-shaped spring clip is longer. When transmitting high-frequency signals, especially when transmitting 224Gbps (base frequency point 56GHz, bandwidth requirement above 70GHz), the crosstalk noise of a pin needs to be coupled to the spring clip and reach the ground plane of the PCB board through a longer path, and the probability of the crosstalk coupling to the pins adjacent to the pin is higher.

[0097] Fig.29 The simulated crosstalk curves of the U-shaped spring, Z-shaped spring and arch-shaped spring provided in the embodiment of the present disclosure are shown in FIG., wherein the horizontal axis is the crosstalk noise frequency (GHz), the vertical axis is the crosstalk (dB), the solid line represents the simulated crosstalk curve of the Z-shaped spring provided in the embodiment, the dotted line represents the simulated crosstalk curve of the U-shaped spring provided in the embodiment, and the dotted line represents the simulated crosstalk curve of the arch-shaped spring provided in the embodiment. Fig.29 It can be seen that the arch-shaped spring piece has the strongest anti-crosstalk ability, the U-shaped spring piece has the second strongest anti-crosstalk ability, and the Z-shaped spring piece has a relatively weaker anti-crosstalk ability, but the Z-shaped spring piece still has better anti-crosstalk ability than the case of opening holes in the prior art.

[0098] Fig.30 The simulated crosstalk curve of the Z-shaped spring provided in the embodiment of the present disclosure with an opening and a shielding net and without an opening, wherein the horizontal axis is the crosstalk noise frequency (GHz), the vertical axis is the crosstalk (dB), the solid line represents the simulated crosstalk curve of the Z-shaped spring provided in the embodiment with an opening and a shielding net, and the dotted line represents the simulated crosstalk curve of the Z-shaped spring provided in the embodiment without an opening. Fig.30 It can be seen that when the distance between the crimping surface of the connector and the crimping surface of the opposite end is the same, if openings (air holes) are set around the Z-shaped spring piece, the ability to suppress crosstalk weakens as the frequency of the crosstalk noise increases, and the overall crosstalk suppression ability is lower than that of the Z-shaped spring piece without an opening.

[0099] The connector provided in the embodiment of the present disclosure is suitable for a high-speed connector, and is particularly suitable for a high-speed backplane connector and a high-speed buckle plate connector connected to a PCB.

[0100] In a second aspect, an embodiment of the present disclosure provides an electronic device.
