Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to a connector. Background Art

[0002] With the rapid development of science and technology, data processing speed and bandwidth are constantly improving. Accordingly, connectors used to transmit data signals in communication systems also need to support higher-speed and longer-distance data communications.

[0003] High-speed connectors contain multiple terminals, each capable of transmitting different signals. However, crosstalk (for example, unwanted voltage noise interference between adjacent terminals) can occur between these terminals. This problem is particularly severe for compact, high-density connectors. This crosstalk can lead to poor signal transmission quality within high-speed connectors, hindering overall transmission speed improvements. Utility Model Content

[0004] In order to solve the above technical problems, the present application provides a connector. The present application is introduced from multiple aspects below, and the implementation methods and beneficial effects of the following multiple aspects can be referenced to each other.

The connecting terminal is disposed opposite the housing. The shielding structure is disposed between the connecting terminal and the housing. Furthermore, the shielding structure is made of a wave-absorbing material.

[0006] In the above-mentioned connector, since the material of the shielding structure is an absorbing material, the electromagnetic waves radiated outward by the connecting terminal during operation can be absorbed by the shielding structure and will not continue to propagate inside the connector, thereby preventing other connecting terminals inside the connector from receiving the electromagnetic waves radiated by the connecting terminal, effectively alleviating the crosstalk problem between multiple connecting terminals, and helping to improve the transmission rate of the connector.

[0007] In a possible implementation of the first aspect above, the shielding structure is a ring-shaped structure, a sheet-shaped structure, a strip-shaped structure, or a cylindrical structure.

[0008] In a possible implementation of the first aspect above, there are one or more shielding structures, and the multiple shielding structures are arranged in a rectangular array or a circular array.

[0009] In a possible implementation of the first aspect, the shielding structure is mounted on an inner surface of the housing, and the inner surface of the housing faces the connecting terminal.

[0010] In a possible implementation of the first aspect, the shielding structure covers at least a portion of the inner surface of the shell.

[0011] In a possible implementation of the first aspect above, the shielding structure is fixedly connected to the inner surface of the shell by injection molding, welding, or attachment.

[0012] In a possible implementation of the first aspect above, the shell is an annular structure, a sheet structure, a U-shaped structure, or a box-shaped structure.

[0026] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0027] The embodiment of the present application is used to provide a connector. The connector can be applied to information technology (IT) equipment (for example, equipment in the fields of traditional computers, the Internet, etc.), communication technology (CT) equipment (for example, equipment in the field of traditional telecommunications), and other electronic devices. In some embodiments, the electronic device may be a computer, a switch, a router, a blade server, a rack server, a gateway, a supercomputing cluster, etc., and this application does not impose specific restrictions on this. In some embodiments, the connector can be a high-speed input / output (IO) connector, a cable connector, etc. The connector can be a 112G or higher connector, for example, a 224G connector. This application does not impose specific restrictions on this.

[0028] Figure 1 The following shows an exemplary application scenario of the connector in the embodiment of the present application. Figure 1 One end of the first connector 100 is used to connect to a first electronic device. The other end of the first connector 100 is connected to the second connector 200. The other end of the second connector 200 is used to connect to a second electronic device. In this way, data can be transmitted between the first electronic device and the second electronic device through the connector assembly 10 (first connector 100 and second connector 200). Specifically, the first connector 100 can be provided with multiple connection terminals inside, and each of the multiple connection terminals can be plugged into the second connector 200. Each connection terminal of the first connector 100 can transmit a different data signal.

[0029] It is worth noting that each connection terminal inside the first connector 100 radiates electromagnetic waves when transmitting signals. If the electromagnetic waves are coupled to other devices (eg, antennas, other connector components, etc.), they may affect the normal operation of other devices.

[0030] To this end, in one implementation, the first connector includes a metal shielding housing. The connecting terminals are disposed within the metal shielding housing. The metal shielding housing can reflect electromagnetic waves radiated outward from the connecting terminals, thereby preventing the electromagnetic waves radiated from the connecting terminals from spreading outside the metal shielding housing, thereby preventing the first connector from affecting the normal operation of other devices.

[0031] However, the above solution cannot prevent crosstalk between the multiple connection terminals within the first connector (for example, unwanted voltage noise interference between adjacent connection terminals). For example, when transmitting a signal, one connection terminal may radiate electromagnetic waves. After being reflected by the housing, these electromagnetic waves continue to propagate inside the housing and are received by another connection terminal. This in turn interferes with another signal transmitted by the other connection terminal, resulting in a decrease in signal transmission quality.

[0032] To this end, in another implementation, a metal shielding sheet is provided inside the first connector. A plurality of connection terminals are distributed in a rectangular array. The metal shielding sheet is provided between two adjacent rows of connection terminals. In this way, during the propagation process, the electromagnetic waves radiated by the connection terminals in a certain row will be reflected back by the metal shielding sheet to the area where the connection terminals in that row are located, rather than being transmitted to the area where the connection terminals in another row are located, thereby avoiding crosstalk between the connection terminals in the two adjacent rows. However, the space inside the first connector is limited, and therefore the size of the shielding sheet is limited, and the shielding sheet cannot completely isolate the crosstalk between adjacent connection terminals. For example, after the electromagnetic waves radiated by one connection terminal in a certain row are reflected back by the shielding sheet, they will continue to propagate and be received by another connection terminal in the row.

[0033] In order to solve the above problems, the present application provides a connector. The connector includes a shielding structure, which is arranged between the connecting terminal and the shell, and the material of the shielding structure is an absorbing material (for example, a type of material that can absorb the electromagnetic wave energy propagating to the surface of the absorbing material). The electromagnetic waves radiated by the connecting terminal can be absorbed by the shielding structure instead of being reflected. In this way, the propagation path of the electromagnetic wave can be effectively blocked, thereby reducing the crosstalk between the multiple connecting terminals. At the same time, it can also effectively prevent the electromagnetic waves radiated by the connecting terminal from spreading to the outside of the connector, thereby reducing the impact of the first connector on other devices (for example, antennas, other connector components, etc.). Therefore, the connector can have a higher data transmission rate.

[0034] The following continues to take the first connector 100 as an example to describe the technical solution of the present application in detail with reference to the accompanying drawings.

[0035] Figure 2A FIG. 1 shows an exemplary structure of the first connector 100 in an embodiment of the present application. Figure 2B FIG. 1 shows an exemplary arrangement of the shielding structure 130 in the first connector 100 in an embodiment of the present application. Figure 2A and Figure 2B Structural features of the shielding structure 130 are shown as areas filled with dots.

[0036] refer to Figure 2A and Figure 2BThe first connector 100 includes a housing 110 , a connecting terminal 120 and a shielding structure 130 .

[0037] The housing 110 is used to protect and support the connecting terminal 120. The material of the housing 110 can be metal. The housing 110 and the connecting terminal 120 are arranged opposite to each other. For example, Figure 2A and Figure 2B In the illustrated embodiment, the housing 110 is a rectangular ring-shaped structure, comprising a first portion 111, a second portion 112, a third portion 113, and a fourth portion 114, which are connected end to end. The first portion 111 and the third portion 113 are arranged opposite each other along the X-direction, and the second portion 112 and the fourth portion 114 are arranged opposite each other along the Y-direction. For example, the X-direction and the Y-direction may be perpendicular to each other. The housing 110, which has a rectangular ring structure, is arranged around the connecting terminal 120. The first portion 111, the second portion 112, the third portion 113, and the fourth portion 114 are respectively arranged opposite each other to the connecting terminal 120. Furthermore, along the X-direction, the first portion 111 and the third portion 113 are located on opposite sides of the connecting terminal 120, respectively; and along the Y-direction, the second portion 112 and the fourth portion 114 are located on opposite sides of the connecting terminal 120, respectively.

[0038] The shielding structure 130 is provided between the housing 110 and the connecting terminal 120. For example, Figure 2A and Figure 2B In the illustrated embodiment, shielding structure 130 is also a rectangular ring structure, comprising a first shielding portion 131, a second shielding portion 132, a third shielding portion 133, and a fourth shielding portion 134, which are connected end to end. First shielding portion 131 and third shielding portion 133 are disposed opposite each other along the X-direction, while second shielding portion 132 and fourth shielding portion 134 are disposed opposite each other along the Y-direction. Along the X direction, the first shielding portion 131 of the shielding structure 130 is located between the first portion 111 of the shell 110 and the connecting terminal 120, that is, along the X direction, the projection area of ​​the first shielding portion 131 on the first portion 111 at least partially overlaps with the projection area of ​​the connecting terminal 120 on the first portion 111; along the Y direction, the second shielding portion 132 of the shielding structure 130 is located between the second portion 112 of the shell 110 and the connecting terminal 120, that is, along the Y direction, the projection area of ​​the second shielding portion 132 on the second portion 112 at least partially overlaps with the projection area of ​​the connecting terminal 120 on the second portion 112; similarly, along the X direction, the third shielding portion 133 of the shielding structure 130 is located between the third portion 113 of the shell 110 and the connecting terminal 120; along the Y direction, the fourth shielding portion 134 of the shielding structure 130 is located between the fourth portion 114 of the shell 110 and the connecting terminal 120.

[0039] The shielding structure 130 is made of an absorbing material. Thus, the electromagnetic waves radiated outward from the connection terminals 120 can be absorbed by the shielding structure 130 and will not be reflected back by the housing 110 and propagate inside the housing 110, thereby avoiding crosstalk between the multiple connection terminals 120.

[0040] Taking the first connection terminal 121 and the second connection terminal 122 as an example, the first connection terminal 121 and the second connection terminal 122 are respectively used to transmit different data signals. When the first connection terminal 121 and the second connection terminal 122 are in operation, the first connection terminal 121 will radiate electromagnetic waves outward. When these electromagnetic waves are transmitted to the surface of the shielding structure 130, they are absorbed by the shielding structure 130, rather than continuing to transmit to the housing 110, being reflected back by the housing 110, and propagating within the housing 110. This prevents the second connection terminal 122 from receiving the electromagnetic waves radiated by the first connection terminal 121, thereby effectively reducing the interference of the first connection terminal 121 on the second connection terminal 122. Correspondingly, the electromagnetic waves radiated outward from the second connection terminal 122 will also be absorbed by the shielding structure 130, rather than continuing to transmit to the housing 110, being reflected back by the housing 110, and propagating within the housing 110. In this way, the first connection terminal 121 can be prevented from receiving electromagnetic waves radiated by the second connection terminal 122, thereby effectively reducing the interference of the second connection terminal 122 on the first connection terminal 121. In this way, the resonance amplitude between the first connection terminal 121 and the second connection terminal 122 can be effectively reduced, and the crosstalk problem between the first connection terminal 121 and the second connection terminal 122 can be improved, thereby facilitating an increase in the data transmission rate of the first connector 100.

[0041] Secondly, because the shielding structure 130 can absorb the electromagnetic waves radiated by the connecting terminal 120, the electromagnetic waves radiated by the connecting terminal 120 will not propagate outside the first connector 100, thereby avoiding any impact on other devices (e.g., antennas, other connector components, etc.), effectively improving the electromagnetic compatibility (EMC) of the first connector 100. Electromagnetic compatibility refers to the ability of a device or system to operate in accordance with requirements in its electromagnetic environment and not cause intolerable electromagnetic interference to any other device in the environment.

[0042] In addition, the shielding structure 130 provided in the present application has a relatively simple structure and occupies a small space, which is conducive to achieving a miniaturized design of the first connector 100 .

[0043] It is understandable that the above Figure 2A and Figure 2BIn the illustrated embodiment, the housing 110 is a rectangular ring structure, but the present application is not limited thereto. In other embodiments, the housing 110 may also be other ring structures, for example, regular ring structures such as a circular ring structure or a pentagonal ring structure, or other irregular ring structures of different shapes. In other embodiments, the housing 110 may not be a ring structure.

[0044] For example, Figure 3A and Figure 3B FIG1 shows exemplary structures of the housing 110 in some other embodiments of the present application. Figure 3A In some implementations, the housing 110 may be a U-shaped structure. For example, the housing 110 may include a fifth portion 115, a sixth portion 116, and a seventh portion 117. The fifth portion 115 and the seventh portion 117 extend along the X direction, respectively, and are disposed opposite to each other along the Y direction. The sixth portion 116 extends along the Y direction, and its two ends are connected to the fifth portion 115 and the seventh portion 117, respectively, so that the housing 110 has a U-shaped structure. Figure 3B In other implementations, the housing 110 may also be a sheet-like structure and extend along the XY plane. For example, the housing 110 may be parallel to the XY plane, i.e., the housing 110 is a planar sheet-like structure. In another example, the housing 110 may extend along the XY plane while being slightly convex or concave, i.e., the housing 110 is a curved sheet-like structure.

[0045] It should be noted that Figures 2A to 3B The form of the housing 110 is only partially shown and does not constitute a specific limitation on the implementation of the present application. In some other implementations, the housing 110 may also be a box-shaped structure. For example, the housing 110 may be a semi-enclosed box-shaped structure with one end open. Figure 2A and Figure 2B The bottom wall is added to the rectangular ring-shaped shell 110 shown in the figure. The bottom wall extends along the XY plane and covers one end opening of the rectangular ring-shaped shell 110, thereby obtaining a semi-closed box-shaped shell 110. For example, the shell 110 can also be a closed box-shaped structure. Figure 2A and Figure 2B A bottom wall and a top wall are added to the rectangular ring-shaped shell 110 shown. Both the bottom wall and the top wall extend along the XY plane and are respectively covered on the two end openings of the rectangular ring-shaped shell 110, thereby obtaining a closed box-shaped shell 110.

[0046] After introducing the exemplary structure of the housing 110 , the exemplary structure of the shielding structure 130 will be introduced below with reference to the accompanying drawings.

[0047] In some embodiments of the present application, the shielding structure 130 may cover the entire area of ​​the inner surface of the housing 110, wherein the inner surface of the housing 110 refers to the surface of the housing 110 facing the connection terminal 120. Figure 2A and Figure 2B In the example shown, the first shielding portion 131 of the shielding structure 130 covers the entire area of ​​the inner surface of the first portion 111 of the housing 110. It can also be understood that, along the X direction, the projection area of ​​the first shielding portion 131 on the first portion 111 covers the entire area of ​​the inner surface of the first portion 111; the second shielding portion 132 of the shielding structure 130 covers the entire area of ​​the inner surface of the second portion 112 of the housing 110. It can also be understood that, along the Y direction, the projection area of ​​the second shielding portion 132 on the second portion 112 covers the entire area of ​​the inner surface of the second portion 112. area; the third shielding portion 133 of the shielding structure 130 covers the entire area of ​​the inner surface of the third portion 113 of the shell 110, which can also be understood as, along the X direction, the projection area of ​​the third shielding portion 133 on the third portion 113 covers the entire area of ​​the inner surface of the third portion 113; the fourth shielding portion 134 of the shielding structure 130 covers the entire area of ​​the inner surface of the fourth portion 114 of the shell 110, which can also be understood as, along the Y direction, the projection area of ​​the fourth shielding portion 134 on the fourth portion 114 covers the entire area of ​​the inner surface of the fourth portion 114.

[0048] In some other embodiments of the present application, the shielding structure 130 may also cover a local area of ​​the inner surface of the housing 110 .

[0049] For example, Figures 4A to 4D FIG. 1 shows exemplary structures of the shielding structure 130 in some other embodiments of the present application. Figure 4A In some implementations, the housing 110 is Figure 3A The shielding structure 130 covers the entire area of ​​the inner surface of the sixth portion 116 of the housing 110, but does not cover the inner surfaces of the fifth portion 115 and the seventh portion 117 of the housing 110. Figure 4B In some other implementations, the housing 110 is Figure 3A The shielding structure 130 covers a partial area of ​​the inner surface of the sixth portion 116 of the housing 110, does not cover another partial area of ​​the inner surface of the sixth portion 116, and does not cover the inner surfaces of the fifth portion 115 and the seventh portion 117. Figure 4C and Figure 4D In some other implementations, the housing 110 is Figure 3B In the illustrated embodiment, the shielding structure 130 covers a partial area of ​​the sheet-shaped housing 110 .

[0050] It should be noted that Figures 4A to 4D It only shows the arrangement of part of the shielding structure 130 and does not constitute a specific limitation on the implementation of this application. Figures 4A to 4D The shape of the shell in the illustrated embodiment is not limited to a U-shaped structure or a sheet-shaped structure. In other embodiments, the shell 110 may also be replaced with a ring-shaped structure or a box-shaped structure, and this application does not impose any specific restrictions on this.

[0051] The shielding structure 130 in the present application can have various forms. In some implementations, the shielding structure 130 can be a ring structure, for example, Figure 2A and Figure 2B The rectangular ring structure in the example shown, or other ring structures, for example, regular ring structures such as circular ring structures or pentagonal ring structures, or other irregular ring structures of special shapes. In some other implementations, the shielding structure 130 can also be a sheet structure, for example, Figure 4A and Figure 4C The sheet-like structure extending along the XY plane in the example shown. In some other implementations, the shielding structure 130 may also be a strip-like structure, for example, Figure 4B The strip structure extending along the Z direction in the example shown. In some other implementations, such as Figure 4D As shown, the shielding structure 130 can also be a cylindrical structure. It can be understood that Figure 2A 、 Figure 2B 、 Figures 4A to 4D It only shows the form of part of the shielding structure 130 and does not constitute a specific limitation on the implementation of the present application.

[0052] The present application does not specifically limit the number of shielding structures 130. In some embodiments of the present application, such as Figure 2A 、 Figure 2B 、 Figures 4A to 4C As shown, the number of shielding structures 130 can be one. In other embodiments of the present application, the number of shielding structures 130 can also be multiple (for example, two, three, four, five, etc.), for example Figure 4D In the illustrated embodiment, the number of shielding structures 130 is twenty-four. In some implementations, the plurality of shielding structures 130 may be arranged in a rectangular array, for example Figure 4D In the illustrated embodiment, twenty-four shielding structures 130 form a 3×8 rectangular array. In other implementations, the shielding structures 130 may be arranged in a circular array. For example, the shielding structures 130 may be arranged in a plurality of concentric rings to form a circular array. In still other implementations, some of the shielding structures 130 may be arranged in a rectangular array, while others may be arranged in a circular array to form a combined array.

[0053] In some embodiments of the present application, the shielding structure 130 may be installed on the inner surface of the housing 110 .

[0054] In some implementations, the shielding structure 130 may be fixedly connected to the inner surface of the housing 110 by injection molding, welding, or attachment. For example, when the housing 110 and the shielding structure 130 are fixedly connected by attachment, the housing 110 and the shielding structure 130 may be cleaned and pre-treated to ensure that their surfaces are flat and free of impurities. The housing 110 and the shielding structure 130 may then be tightly attached together by high temperature or pressure to achieve a fixed connection between the housing 110 and the shielding structure 130.

[0055] In some other embodiments of the present application, the shielding structure 130 may also be installed on other devices.

[0056] In some implementations, the first connector 100 further includes insulating plastic, and the shielding structure 130 can be mounted on the insulating plastic. Figure 5 FIG. 1 shows an exemplary structure of the insulating plastic 140 in an embodiment of the present application. Figure 5 The areas filled with grid lines in the figure show the structural features of the insulating plastic 140 .

[0057] refer to Figure 5 The connecting terminals 120, insulating plastic 140, shielding structure 130, and housing 110 are sequentially arranged from the inside out, thereby forming a nested structure. The connecting terminals 120 and shielding structure 130 are both mounted on the insulating plastic 140, and two adjacent connecting terminals, for example, the first connecting terminal 121 and the second connecting terminal 122, are separated by the insulating plastic 140. This prevents mutual conduction between the first connecting terminal 121 and the second connecting terminal 122. The specific implementation of the shielding structure 130 being mounted on the insulating plastic 140 can be referred to the specific implementation of the shielding structure 130 being mounted on the housing 110, and will not be further described here.

[0058] There may be a gap between the shielding structure 130 and the housing 110 (eg Figure 5 The gap G1) in the example shown may also be in contact, and this application does not impose any specific limitation on this.

[0059] It is understandable that the above Figure 5The shape of the insulating plastic 140 is merely schematically illustrated. In other embodiments, the insulating plastic 140 may have other shapes. For example, the insulating plastic 140 may have other annular structures, such as regular annular structures such as circular or pentagonal annular structures, or other irregular annular structures. For example, the insulating plastic 140 may have a U-shaped structure, a box-shaped structure, a sheet-like structure, a strip-like structure, etc., but this application does not limit these.

[0060] In some other implementations, the first connector 100 may further include a support member for mounting the shielding structure 130, with the shielding structure 130 mounted on the support member. For example, the support member may be disposed between the housing 110 and the insulating plastic 140, and the shielding structure 130 may be mounted on a surface of the support member facing the insulating plastic 140.

[0061] In some other implementations, when there are multiple shielding structures 130 , the multiple shielding structures 130 can be installed on different devices respectively. For example, one of the two shielding structures 130 is installed on the housing 110 , and the other is installed on the insulating plastic 140 .

[0062] The present application does not impose any specific limitation on the installation method of the shielding structure 130 , as long as the shielding structure 130 can alleviate the above-mentioned crosstalk problem.

[0063] In some embodiments of the present application, the absorbing material may include at least one of conductive plastic, graphene, silicon carbide, or conductive polymer.

[0064] In some embodiments of the present application, the material of the housing 110 may not be entirely metal. For example, Figure 2A and Figure 2B In the illustrated embodiment, the first portion 111 of the rectangular ring-shaped housing 110 is made of metal, and the second portion 112 , the third portion 113 and the fourth portion 114 are made of non-metal, such as plastic.
