[0045] To make the objectives, technical solutions, and beneficial effects of this application clearer, the following detailed description, in conjunction with the accompanying drawings and specific embodiments, further illustrates this application. It should be understood that the specific embodiments described in this specification are merely for explaining this application and are not intended to limit it.

[0046] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0047] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0048] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0049] With the continuous development of electronic technology, crosstalk in high-speed backplane connectors has become a critical issue for signal integrity. Existing backplane connectors typically achieve overlap by designing a bump on the shield and using the bump to contact the pins. However, this connection method usually requires avoiding the opposite side of the bump to prevent rigid contact between the bump and the shield, which could affect the product's mechanical properties. This results in the shield near the bump not being able to overlap, only ensuring single-sided ground return, and the limited overlap points on the shield significantly reduce connector performance.

[0050] To address the aforementioned problems, in the embodiments of this application, reference is made to... Figures 1 to 9 This application provides a backplane connector having a first direction X, a second direction Y, and a third direction Z that intersect each other in pairs. For example, the backplane connector has a first direction X, a second direction Y, and a third direction Z that are perpendicular to each other in pairs. Here, "perpendicular" refers to a state where the angle formed by lines and lines, lines and surfaces, or surfaces is 89° to 91°.

[0051] Specifically, the backplane connector includes a female connector 100 and a male connector 200, which are electrically connected.

[0052] Reference Figures 4 to 8 The female connector 100 includes: a first base 110, a shielding component 120, and a signal module 130.

[0053] Specifically, the shielding assembly 120 includes: a shielding housing 121, a first shielding member 122, and a second shielding member 123. The shielding housing 121 is disposed on the first base 110, and a shielding cavity 1211 is formed inside the shielding housing 121. The first shielding member 122 includes: a first shielding part 1221 and a second shielding part 1222. Both the first shielding part 1221 and the second shielding part 1222 are disposed inside the shielding cavity 1211. The second shielding part 1222 protrudes from the first shielding part 1221. The first shielding part 1221 is in contact with the shielding housing 121, and the second shielding part 1222 is spaced apart from the housing 121. The second shielding part 1222 is used for electrical connection with external components. The second shielding member 123 is disposed between the second shielding part 1222 and the shielding housing 121 to connect the second shielding part 1222 and the shielding housing 121.

[0054] The first base 110 is made of an insulating material. For example, the first base 110 may be made of polybutylene terephthalate (PBT), nylon, polycarbonate (PC) or liquid crystal polymer (LCP), but is not limited thereto.

[0055] The shielding shell 121 is made of conductive plastic, which is a plastic material with conductive properties. This conductivity is typically achieved by adding conductive fillers to a plastic matrix. For example, the shielding shell 121 is made of conductive plastic with at least one of the following added to the plastic matrix: metal powder (such as copper, silver, or aluminum), carbon fiber, or carbon black. However, it is not limited to this type of material.

[0056] The first shielding element 122 may be made of conductive metal. For example, the first shielding element 122 may be made of nickel silver, stainless steel or tinplate, but is not limited to these.

[0057] The first shielding part 1221 and the second shielding part 1222 can be integrally formed, that is, the first shielding part 1221 and the second shielding part 1222 are a one-piece structure. For example, the first shielding part 1221 and the second shielding part 1222 are integrally die-cast, but not limited thereto. The first shielding part 1221 and the second shielding part 1222 can also be separately arranged, and the first shielding part 1221 and the second shielding part 1222 are fixedly connected. For example, the second shielding part 1222 is fixedly connected to the first shielding part 1221 by welding or other processes. This application does not make specific limitations and can be specifically set according to the actual situation. For example, in this application, the first shielding part 1221 and the second shielding part 1222 are integrally formed to facilitate the processing and forming of the first shielding part 122 and improve the overall assembly efficiency of the female connector 100.

[0058] Reference Figure 9 The male connector 200 includes a second base 210, a plurality of first pins 220 and a plurality of second pins 230. The plurality of first pins 220 and the plurality of second pins 230 are all disposed on the second base 210, and the plurality of first pins 220 and the plurality of second pins 230 are arranged alternately in the first direction X.

[0059] The second base 210 is made of an insulating material. For example, the second base 210 may be made of polybutylene terephthalate (PBT), nylon, polycarbonate (PC) or liquid crystal polymer (LCP), but is not limited thereto.

[0060] The first pin 220 and the second pin 230 are made of conductive metal. For example, the first pin 220 and the second pin 230 are made of copper or aluminum, but are not limited thereto.

[0061] Specifically, the first pin 220 passes through the shielding cavity 1211 to be electrically connected to the second shielding part 1222; the second pin 230 is electrically connected to the signal connector 132 to realize signal transmission.

[0062] Understandably, this application provides a second shielding member 123 between the second shielding part 1222 and the shielding housing 121 to electrically connect the second shielding part 1222 and the shielding housing 121. This enables multiple different positions of the first shielding member 122 to be electrically connected to the shielding housing 121, forming a return path from the second shielding part 1222 to the first shielding part 1221 to the shielding housing 121, and a return path from the second shielding part 1222 to the second shielding member 123 to the shielding housing 121. This increases the return path of the shielding assembly 120, optimizes signal crosstalk, improves the shielding performance and crosstalk performance of the female connector 100, and ultimately improves the shielding performance and crosstalk performance of the backplane connector.

[0063] In one embodiment, reference is made to Figures 5 to 8 The first shielding component 122 and the second shielding component 123 are arranged sequentially in the first direction X.

[0064] Along the first direction X, the surface of the first shielding portion 1221 facing away from the second shielding member 123 protrudes to the side away from the second shielding member 123 to form the second shielding portion 1222, and the surface of the first shielding portion 1221 near the second shielding member 123 is recessed to the side away from the second shielding member 123 to form a groove 1223, so as to facilitate the processing and forming of the second shielding portion 1222 and the groove 1223 on the first shielding portion 1221, thereby improving the overall forming efficiency of the first shielding member 122 and ultimately improving the overall processing efficiency of the female connector 100.

[0065] The second shielding part 1222 and the groove 1223 can be integrally cast with the first shielding part 1221 using a casting mold; alternatively, the first shielding part 1221 can be die-cast using a casting mold, and the second shielding part 1222 and the groove 1223 can be stamped onto the first shielding part 1221 using a stamping device, but this is not a limitation. This application does not make specific limitations, and the choice can be made according to the actual situation.

[0066] In one embodiment, reference is made to Figure 7 Multiple second shielding portions 1222 are provided, and the multiple second shielding portions 1222 are spaced apart in the second direction Y. The second shielding member 123 is disposed between the multiple second shielding portions 1222 and the shielding housing 121 to connect the multiple second shielding portions 1222 and the shielding housing 121, thereby further increasing the return path of the shielding assembly 120, optimizing signal crosstalk, improving the shielding performance and crosstalk performance of the female connector 100, and ultimately improving the shielding performance and crosstalk performance of the backplane connector.

[0067] In one embodiment, the second shield 123 is made of conductive plastic, but is not limited thereto.

[0068] This application uses conductive plastic to make the second shield 123, so that the second shield 123 has a certain elasticity, and the second shield 123 is elastically connected to the second shield 1222, thereby enabling the female connector 100 and the male connector 200 to be assembled with each other. When the first pin 220 contacts the second shield 1222, the second shield 123 can be deformed, which facilitates the assembly of the female connector 100 and the male connector 200 and improves the assembly efficiency of the backplane connector.

[0069] In one embodiment, reference is made to Figures 7 to 8 The shielding assembly 120 further includes a third shielding member 124, which is disposed within the shielding cavity 1211.

[0070] The third shielding element 124 may be made of conductive metal. For example, the third shielding element 124 may be made of nickel silver, stainless steel or tinplate, but is not limited thereto.

[0071] Specifically, the third shielding component 124 includes: a shielding body 1241 and a spring piece 1242.

[0072] The shielding body 1241 is in contact with the shielding shell 121, and the shielding body 1241 and the first shielding part 1221 are arranged opposite each other in the first direction X. Multiple spring parts 1242 are provided, and multiple spring parts 1242 are all provided on the shielding body 1241. The multiple spring parts 1242 are arranged sequentially in the second direction Y. Each spring part 1242 is arranged opposite to a corresponding second shielding part 1222 in the first direction X. The spring part 1242 is used for electrical connection with external components, and relative displacement can occur between the spring part 1242 and the shielding body 1241.

[0073] The shielding body 1241 and the spring contact portion 1242 can be integrally formed, meaning they are a single, integrated structure. For example, the shielding body 1241 and the spring contact portion 1242 can be die-cast integrally, but this is not a limitation. Alternatively, the shielding body 1241 and the spring contact portion 1242 can be separately configured, and fixedly connected, for example, the spring contact portion 1242 can be fixedly connected to the shielding body 1241 through welding or other processes. This application does not impose specific limitations and can be configured according to actual circumstances. For example, in this application, the shielding body 1241 and the spring contact portion 1242 are integrally formed to facilitate the processing and forming of the third shielding component 124, thereby improving the overall assembly efficiency of the female connector 100.

[0074] The spring portion 1242 of the third shielding member 124 is electrically connected to the first pin 220.

[0075] This application provides a third shield 124, and uses the spring portion 1242 of the third shield 124 to electrically connect with the first pin 220 to form a return path from the first pin 220 to the third shield 124 to the shield housing 121. This further increases the return path of the shielding assembly 120, optimizes signal crosstalk, improves the shielding performance and crosstalk performance of the female connector 100, and ultimately improves the shielding performance and crosstalk performance of the backplane connector.

[0076] In one embodiment, reference is made to Figure 8 The shielding housing 121 has a partition 1212, which is disposed inside the shielding cavity 1211 and between the shielding body 1241 and the first shielding part 1221 to separate the two.

[0077] In one embodiment, reference is made to Figures 4 to 5 The shielding housing 121 also has a receiving cavity 1213, which is separated from the shielding cavity 1211.

[0078] The female connector 100 also includes a signal module 130, which is used to transmit signals.

[0079] Specifically, the signal module 130 includes: an insulating housing 131, a signal connector 132, and a fourth shielding component 133.

[0080] An insulating housing 131 is disposed on one side of the shielding housing 121 in the third direction Z; some signal connectors 132 are disposed inside the insulating housing 131, and another part of the signal connectors 132 are disposed inside the accommodating cavity 1213; multiple fourth shielding members 133 are disposed, and the multiple fourth shielding members 133 are arranged at intervals in the second direction Y, and the multiple fourth shielding members 133 are respectively disposed on the outer surface of the insulating housing 131 that is disposed opposite to each other in the second direction Y, and the fourth shielding members 133 are electrically connected to the shielding housing 121.

[0081] Specifically, the second pin 230 passes through the accommodating cavity 1213 to be electrically connected to the signal connector 132 located in the accommodating cavity 1213, so as to realize signal transmission.

[0082] The insulating shell 131 may be made of polyethylene (PE), polyvinyl chloride (PVC) or polytetrafluoroethylene (PTFE), but is not limited to these.

[0083] The signal connector 132 is made of a conductive metal. For example, the signal connector 132 is made of copper or aluminum, but is not limited thereto.

[0084] The fourth shield 133 may be made of conductive metal. For example, the fourth shield 133 may be made of nickel silver, stainless steel or tinplate, but is not limited thereto.

[0085] Understandably, this application places some signal connectors 132 inside the insulating housing 131 to achieve insulation isolation between the signal connectors 132 and the fourth shield 133 and the shield housing 121, preventing short circuits caused by contact between the signal connectors 132 and the fourth shield 133 and the shield housing 121, thus ensuring normal use of the connectors. At the same time, by setting the fourth shield 133, signal crosstalk is further optimized, improving the shielding performance and crosstalk performance of the female connector 100, and ultimately improving the shielding performance and crosstalk performance of the backplane connector.

[0086] In one embodiment, the receiving cavity 1213 and the shielding cavity 1211 are alternately arranged in the first direction X. That is, the signal connector 132 located in the receiving cavity 1213 and the first shield 122 and the third shield 124 located in the shielding cavity 1211 are alternately arranged in the first direction X to form an encircling shield for the signal connector 132, shorten the return path, optimize signal crosstalk, and improve the shielding performance and crosstalk performance of the female connector 100.

[0087] In one embodiment, reference is made to Figures 4 to 5 The shielding housing 121 has a receiving groove 1214 on the side near the signal module 130. At least part of the insulating housing 131 is embedded in the receiving groove 1214. The cooperation between the receiving groove 1214 and the insulating housing 131 is used to achieve the initial fixation of the insulating housing 131, thereby achieving the initial fixation of the signal module 130, preventing the components from shaking at will, ensuring the normal use of the connector, and making the overall structure compact and reducing the space occupied by the female connector 100.

[0088] In one embodiment, reference is made to Figure 5 The first base 110 has a first through hole 111 and a second through hole 112. The first through hole 111 is connected to the shielding cavity 1211, and the second through hole 112 is connected to the accommodating cavity 1213.

[0089] The first pin 220 passes through the first through hole 111 to be electrically connected to the second shielding part 1222 and the spring part 1242; the second pin 230 passes through the second through hole 112 to be electrically connected to the signal connector 132 to realize signal transmission.

[0090] In one embodiment, reference is made to Figure 9 The male connector 200 also includes a male grounding module 240 and a male signal module 250.

[0091] Specifically, the male-end grounding module 240 and the male-end signal module 250 are both disposed on the second base 210, and the male-end grounding module 240 is electrically connected to the first pin 220, and the male-end signal module 250 is electrically connected to the second pin 230.

[0092] Among them, the public terminal signal module 250 is a differential signal module.

[0093] In summary, this application provides a second shielding member 123 between the second shielding part 1222 and the shielding housing 121 to electrically connect the second shielding part 1222 and the shielding housing 121. This enables multiple different positions of the first shielding member 122 to be electrically connected to the shielding housing 121, forming a return path from the second shielding part 1222 to the first shielding part 1221 to the shielding housing 121, and a return path from the second shielding part 1222 to the second shielding member 123 to the shielding housing 121. This increases the return path of the shielding assembly 120, optimizes signal crosstalk, improves the shielding performance and crosstalk performance of the female connector 100, and ultimately improves the shielding performance and crosstalk performance of the backplane connector.

[0094] The above steps are provided only to help understand the method, structure, and core ideas of this application. Those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims.
