Description

Technical Field

[0001] This application relates to the technical field of high-speed backplane connectors, and particularly to a shielding component. Background Art

[0002] The signal transmission between a high-speed backplane connector and a PCB board is usually achieved by crimping the fish-eye terminals of the signal module onto the PCB board. Currently, as the signal transmission rate is getting faster and faster, the shielding treatment of interference signals has become an important issue in high-speed signal transmission.

[0003] The existing shielding treatment generally involves setting a grounding component on the PCB board. There are two facing shielding plates on the outside of the signal module. The shielding plates are inserted into a conductive plate, and there is a lap joint between the shielding plate and the conductive plate. When the fish-eye terminals are crimped onto the PCB board, the conductive plate is lapped with the grounding component. Through the above, the return of interference signals from the shielding plate, the conductive plate to the grounding component is realized, thereby avoiding or reducing the influence of interference signals and achieving the shielding effect.

[0004] However, with the continuous improvement of the signal transmission rate, there is currently an unreliable problem in the contact between the conductive plate and the PCB board. The lap joint point between the conductive plate and the PCB board is uncertain, and the lap joint point is unstable during use, resulting in unstable return of interference signals and making it difficult to adapt to the shielding of high-speed signal transmission. Summary of the Invention

[0005] This application provides a shielding component to solve the technical problem that the current shielding treatment of high-speed backplane connectors is insufficient, resulting in poor high-speed transmission performance.

[0006] This application provides a shielding component, which includes:

[0007] A conductive plate;

[0008] A signal module, on one side of the signal module facing the conductive plate, there are signal terminals;

[0009] An insertion chamber for inserting the signal terminals is formed on the conductive plate;

[0010] Wherein, the conductive plate includes:

[0011] A body, the body has an attachment surface facing the PCB board;

[0012] Elastic bumps, a plurality of elastic bumps are arranged at intervals on the attachment surface, and the elastic bumps are integrally connected with the body;

[0013] Wherein, the material of the conductive plate is conductive plastic.

[0014] To implement the above technical solution, when the body is crimped with the PCB board, multiple elastic bumps are in contact with the surface of the PCB board, achieving a relatively stable and reliable lap joint, so that interference signals can return more stably, improving the shielding reliability and stability; the conductive plate is made of conductive plastic, and the conductive plastic has good elasticity and is not likely to damage the PCB board during the pressing process of the body and the PCB board. The flexibility of the elastic bumps themselves and their integral connection to the body also make the connection between the elastic bumps and the body more reliable and stable.

[0015] As an optional embodiment of this solution, the Shore hardness of the conductive plastic is 50HA - 100HA, and the conductivity of the conductive plastic at a temperature of 25 degrees Celsius is 10 2 -10 4 S / m.

[0016] To implement the above technical solution, a Shore hardness of 50HA - 100HA ensures the elasticity of the elastic bumps and the body, reducing the situation where the elastic bumps are damaged or the PCB board is damaged. The conductivity ensures the return of signals and thus the shielding effect.

[0017] As an optional embodiment of this solution, the elastic bumps are evenly distributed on the attachment surface.

[0018] As an optional embodiment of this solution, the signal module has a thickness direction, a length direction perpendicular to the thickness direction, and a height direction. The height direction is parallel to the insertion direction of the signal terminal. The signal module includes:

[0019] Signal components;

[0020] A first shielding plate and a second shielding plate, the first shielding plate and the second shielding plate are respectively fixed on the outer sides of the signal module facing each other in the thickness direction. The first shielding plate has a first shielding insertion end, and a first contact point protrudes from the first shielding insertion end. The second shielding plate has a second shielding insertion end, and a second contact point protrudes from the second shielding insertion end;

[0021] Wherein, when the signal terminal is inserted to a predetermined position, the first contact point contacts the circumferential inner wall of the insertion chamber to form a lap joint to achieve electrical conduction, and the second contact point contacts the circumferential inner wall of the insertion chamber to form a lap joint to achieve electrical conduction.

[0022] As an optional embodiment of this solution, at least one of the first shielding insertion ends is provided with an extension end along the insertion direction. The insertion chamber has an insertion opening and an insertion bottom wall opposite to the insertion opening. At least one of the insertion bottom walls is provided with an extension hole for the extension end to be inserted;

[0023] Among them, a plurality of third contact points are provided on the extension end. When the extension end is inserted into a predetermined position of the extension hole, the third contact points are in contact with the inner wall of the extension hole to form a plurality of overlapping points to achieve electrical conduction.

[0024] To implement the above technical solution, the third contact point includes two convex points in the length direction and one convex point in the thickness direction, effectively increasing the number of overlapping points formed between the extension end and the conductive plate, improving the overlapping reliability and the signal return stability; and the extension end has a contact surface that forms a surface contact with the inner wall of the extension hole, providing a stable support for other overlapping points during insertion, and further improving the stability of other overlapping points.

[0025] As an optional embodiment of this solution, the extension hole is rectangular, and the third contact point includes at least two third transverse contact points provided on the extension end in the length direction and at least one third longitudinal contact point on the side away from the second shielding plate in the thickness direction. The extension end has a contact surface that is in contact with the inner wall of the extension hole.

[0026] As an optional embodiment of this solution, a limiting portion is integrally provided on the inner wall of the extension hole facing the contact surface. The limiting portion has a limiting surface that is in contact with the contact surface. The length of the limiting portion in the length direction is less than the length of the extension hole in the length direction. When the extension end is inserted into a predetermined position of the extension hole, the limiting portion, the extension hole, and the extension end enclose an avoidance space.

[0027] To implement the above technical solution, the materials of the first shielding plate and the second shielding plate are generally metals, and the material of the conductive plate is conductive plastic with a certain toughness; when the extension end is inserted into the extension hole, one side of the extension end is squeezed by the third longitudinal contact point, causing a large squeezing force between the contact surface and the limiting surface, so that the edge of the extension end in the length direction is squeezed against the inner wall of the extension hole. During the insertion process, the extension end moves along the insertion direction while the edge is squeezed against the inner wall of the extension hole, which may cause the edge to cut the inner wall of the extension hole, resulting in damage to the extension hole and affecting the overlapping reliability of subsequent overlapping points and the signal return stability; in this solution, the limiting portion and the limiting surface are provided and the shape and size of the limiting portion are limited, so that an avoidance space is formed by the limiting portion, the extension hole, and the extension end during the insertion of the extension end, and the edge will not cause an extrusion effect on the inner wall of the extension hole, thus avoiding damage to the inner wall of the extension hole during the assembly process and ensuring the interference signal return effect. Especially in the field of high-speed connectors like this solution, the shielding reliability is ensured.

[0028] As one of the optional embodiments of this solution, the extension hole is a through hole. The plugging bottom wall is also provided with a first hole and a second hole that penetrate along the insertion direction. One end of the second shielding plugging end facing the conductive plate is also provided with a grounding terminal, and the first hole and the second hole are used for the grounding terminal to be plugged and matched.

[0029] As one of the optional embodiments of this solution, at least one of the second shielding plugging ends is provided with a second groove along the insertion direction. There is a blocking wall between the first hole and the second hole to space the first hole and the second hole apart. The blocking wall is plugged and matched with the second groove. The inner wall of the second groove is provided with a fourth contact point. When the blocking wall is plugged into a predetermined position in the second groove, the fourth contact point abuts against the blocking wall to form a lap joint point to achieve electrical conduction.

[0030] To implement the above technical solution, when the blocking wall is plugged and matched with the second groove, a fourth contact point contacts the blocking wall is additionally formed on the inner wall of the second groove, thereby further improving the return lap joint point between the second shielding plate and the conductive plate, improving the return effect, and ensuring high-speed performance.

[0031] As one of the optional embodiments of this solution, the inner wall of the first hole facing the second shielding plugging end is provided with a first limiting block, and the inner wall of the second hole facing the second shielding plugging end is provided with a second limiting block.

[0032] One of the technical solutions in the above technical solution has the following advantages or beneficial effects:

[0033] 1. When the body is crimped with the PCB board, multiple elastic bumps abut against the surface of the PCB board to achieve a relatively stable and reliable lap joint point, so that interference signals can return more stably, improving the shielding reliability and stability; the conductive plate is made of conductive plastic, and the conductive plastic has good elasticity and is not easy to damage the PCB board during the pressing process of the body and the PCB board. The flexibility of the elastic bumps themselves and the setting of being integrally connected to the body also make the connection between the elastic bumps and the body more reliable and stable;

[0034] 2. The setting of the extension end and the extension hole increases the lap joint points between the first shielding plate and the conductive plate in the length direction and the thickness direction, increasing the path for interference signal return, thereby improving the high-speed signal transmission performance. When the extension end is plugged into the extension hole, an avoidance space is set to make the extension end contact the inner wall of the extension hole more stably and safely, thereby avoiding damage to the conductive plate while increasing the lap joint points.

Detailed implementation

[0052] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0053] In the description of the present application, it should be noted that unless otherwise clearly defined and limited, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally represents an "or" relationship between the associated objects before and after without special explanation.

[0054] Figure 1 It is a general structure of a conductive plate in the prior art, which includes a body 1. The body 1 has an attachment surface 1b, and the attachment surface 1b serves as the contact surface when the body 1 is press-fitted to the PCB board. When the body 1 is press-fitted onto the PCB board, the attachment surface 1b forms a surface contact with the surface of the PCB board.

[0055] However, due to various factors such as process limitations and assembly deformation, it is easy to cause this kind of surface contact to be difficult to form a strictly accurate lap joint. For example, after magnifying the attachment surface 1b and the surface of the PCB board by several times, they are uneven, and for example, the attachment surface 1b and the PCB board are unevenly stressed at each point during the press-fitting process. Factors such as the above will all lead to unreliable lap joints generated by surface contact during use. In the process of some ultra-high-speed signal transmissions, this kind of lap joint shielding method is difficult to adapt to.

[0056] Therefore, the exemplary conductive plate disclosed in this article includes a body 1 and elastic bumps 3 integrally connected to the body 1. The overall material is conductive plastic. When the body 1 is press-connected to the PCB board, multiple elastic bumps 3 are in contact with the surface of the PCB board to achieve a relatively stable and reliable lap joint, so that interference signals can return more stably, improving the shielding reliability and stability. Moreover, both the elastic bumps 3 and the body 1 are made of conductive plastic, and the connection between the elastic bumps 3 and the body 1 is relatively reliable and stable, and there are very few cases of falling off or damage.

[0057] The following will further describe Figures 2 - 15 this application in conjunction with the attached

[0058] Referring to Figures 2 - 4 , a shielding component disclosed in this application includes a conductive plate. The conductive plate is in the shape of a rectangular plate and includes a body 1. The two largest opposite sides of the body 1 are respectively an attachment surface 1b and a back surface 1a. Among them, the attachment surface 1b serves as the contact surface when the body 1 is press-connected to the PCB board. The conductive plate further includes elastic bumps 3. A plurality of elastic bumps 3 are arranged at intervals on the attachment surface 1b, and the elastic bumps 3 are integrally connected to the body 1. When the body 1 is press-connected to the PCB board, multiple elastic bumps 3 are in contact with the surface of the PCB board to form a relatively stable and reliable lap joint, so that interference signals can return more stably, improving the shielding reliability and stability. The material of the conductive plate is set as conductive plastic. The conductive plastic has good elasticity and toughness, is not easy to damage the PCB board during the press-fitting process of the body 1 and the PCB board, and can also improve the toughness of the elastic bumps 3 to make the connection between the elastic bumps 3 and the body 1 more reliable and stable. The Shore hardness of the conductive plastic is 50HA - 100HA, and the conductivity of the conductive plastic at a temperature of 25 degrees Celsius is 102 - 104 S / m. The Shore hardness of 50HA - 100HA ensures the elasticity of the elastic bumps 3 and the body 1, reducing the situation where the elastic bumps 3 are damaged or the PCB board is damaged, and the conductivity ensures the return of signals and thus the shielding effect.

[0059] Referring to Figure 2 and Figure 3A plurality of insertion chambers 7 are provided on the backing surface 1a, and the insertion chambers 7 are used for inserting and inserting parts in the later assembly. The elastic bumps 3 are evenly distributed on the attachment surface 1b so that the force of each elastic bump 3 tends to be the same when the attachment surface 1b is pressed against the PCB board, thereby improving the crimping stability.

[0060] Reference Figure 4 , Figure 5 and Figure 6 , the shielding component also includes a signal module 4, the signal module 4 includes a signal component 41, and the signal component 41 is provided with a signal terminal 4a on the side facing the conductive plate, and the signal terminal 4a is fisheye-shaped. The signal module 4 has a thickness direction, a length direction perpendicular to the thickness direction, and a height direction. Among them, the height direction is parallel to the plug-in direction of the signal module 4. The signal module 4 also includes a first shielding plate 5 and a second shielding plate 6, and the first shielding plate 5 and the second shielding plate 6 are riveted and fixed on the two facing outer sides of the signal module 4 in the thickness direction. The first shielding plate 5 has a first shielding plug-in terminal 51 on the side facing the conductive plate, and the second shielding plate 6 has a second shielding plug-in terminal 61 on the side facing the conductive plate. A grounding terminal 612 is also provided on part of the second shielding plug-in terminal 61, specifically, two grounding terminals 612 are provided on the second shielding plug-in terminals 61 spaced from each other. The shielding component also includes the conductive plate involved in Example 1. During assembly, the signal module 4, the first shielding plug-in terminal 51 and the second shielding plug-in terminal 61 are plugged into the plug-in chamber 7.

[0061] Reference Figure 7 The plug-in chamber 7 has a plug-in port 71 and a plug-in bottom wall 72 facing the plug-in port 71 in the insertion direction. Part of the plug-in bottom wall 72 is provided with a signal hole 9 for the signal terminal 4a to pass through. Part of the plug-in bottom wall 72 is provided with a first hole 722 and a second hole 723 for the ground terminal 612 to pass through.

[0062] Reference Figure 5 , Figure 6 ,as well as Figures 8 - 11 , a first contact 511 is protruded on the first shielding plug end 51, and the first contact 511 includes first transverse contacts 511a on both sides of the first shielding plug end 51 in the length direction and a first longitudinal contact 511b arranged on the side of the first shielding plug end 51 away from the second shielding plate 6. A second contact 611 is protruded on the second shielding plug end 61, and the second contact 611 includes second transverse contacts 611a on both sides of the second shielding plug end 61 in the length direction and a second longitudinal contact 611b arranged on the side of the second shielding plug end 61 away from the first shielding plate 5. When the first shielding plug end 51 and the second shielding plug end 61 are inserted into the predetermined position of the plug-in chamber 7, the first contact 511 contacts the circumferential inner wall of the plug-in chamber 7 to form a lap joint to achieve electrical conduction.

[0063] Reference Figures 8 - 9 , Figures 13 - 14 , at least one first shielding plug-in end 51 is provided with an extension end 8 along the insertion direction, and the plug-in bottom wall 72 of at least one plug-in chamber 7 is provided with an extension hole 721 along the insertion direction, and the extension end 8 is in plug-in fit with the extension hole 721. Among them, a plurality of third contact points 10 are provided on the extension end 8. When the extension end 8 is inserted into a predetermined position of the extension hole 721, the third contact points 10 are in contact with the inner wall of the extension hole 721 to form a plurality of overlapping points. The setting of the extension end 8 and the extension hole 721 increases the overlapping points between the first shielding plate 5 and the conductive plate, increases the path for the interference signal to return, and thus improves the high-speed signal transmission performance. The extension hole 721 is rectangular. The third contact points 10 include two third transverse contact points 101 arranged on the extension end 8 in the length direction and a third longitudinal contact point 102 on the side away from the second shielding plate 6 in the thickness direction. The extension end 8 has an abutting surface 81 that abuts against the inner wall of the extension hole 721. When the extension end 8 is inserted into the extension hole 721, the third transverse contact points 101 are in contact with the two inner walls of the extension hole 721 in the length direction, and the third longitudinal contact point 102 is in contact with the inner wall of the extension hole 721 away from the first shielding plate 5. The third contact points 10 include two convex points in the length direction and one convex point in the thickness direction, effectively increasing the number of overlapping points formed by the extension end 8 and the conductive plate, and improving the overlapping reliability and signal return stability. The extension end 8 has an abutting surface 81 that forms a surface contact with the inner wall of the extension hole 721, providing a stable support for other overlapping points during insertion and further improving the stability of other overlapping points.

[0064] Reference Figure 7 , Figures 14 - 15, a limiting portion 11 is integrally protruded on the inner wall of the extending hole 721 facing the abutting surface 81. The limiting portion 11 has a limiting surface 111 that abuts against the abutting surface 81. The length of the limiting portion 11 in the length direction is less than the length of the extending hole 721 in the length direction. When the extending end 8 is inserted into a predetermined position of the extending hole 721, the limiting portion 11, the extending hole 721, and the extending end 8 enclose an avoidance space 12. The materials of the first shielding plate 5 and the second shielding plate 6 are generally metals, and the material of the conductive plate is conductive plastic with certain toughness; when the extending end 8 is inserted into the extending hole 721, one surface of the extending end 8 is squeezed by the third longitudinal contact 102, so that a large squeezing force is generated between the abutting surface 81 and the limiting surface 111, thereby causing the edge of the extending end 8 in the length direction to be squeezed against the inner wall of the extending hole 721. During the insertion process, while the extending end 8 moves along the insertion direction, the edge of the extending end 8 is simultaneously squeezed against the inner wall of the extending hole 721, which may cause the edge to cut the inner wall of the extending hole 721, resulting in damage to the extending hole 721 and affecting the subsequent lap joint reliability of the lap joint point and the signal return stability; in this solution, the limiting portion 11 and the limiting surface 111 are provided, and the shape and size of the limiting portion 11 are limited, so that when the extending end 8 is inserted, the limiting portion 11, the extending hole 721, and the extending end 8 enclose an avoidance space 12, and the edge will not produce a squeezing effect on the inner wall of the extending hole 721, thereby avoiding damage to the inner wall of the extending hole 721 during the assembly process and ensuring the interference signal return effect. Especially in the field of high-speed connectors like this solution, the shielding reliability is ensured. In other alternative embodiments, the limiting portion 11 may also be of other shapes to form avoidance spaces 12 of different shapes.

[0065] Refer to Figure 7 , Figures 10 - 12, at least one second shielding insertion end 61 is provided with a second groove 613 along the insertion direction. The first hole 722 and the second hole 723 are spaced apart to form a blocking wall 13. When the grounding terminal 612 passes through the first hole 722 and the second hole 723 respectively, the blocking wall 13 is inserted and matched with the second groove 613. A fourth contact 14 is provided on the inner wall of the second groove 613. When the blocking wall 13 is inserted into the second groove 613 at a predetermined position, the fourth contact 14 abuts against the blocking wall 13 to form a lap joint point to achieve electrical conduction. When the blocking wall 13 is inserted and matched with the second groove 613, a fourth contact 14 is additionally formed on the inner wall of the second groove 613 in contact with the blocking wall 13, improving the return lap joint point between the second shielding plate 6 and the conductive plate, thereby improving the return effect and ensuring high-speed performance. The inner wall of the first hole 722 facing the second shielding insertion end 61 is provided with a first limiting block 7221. The length of the first limiting block 7221 in the length direction is less than the length of the first hole 722 in the length direction. When the second groove 613 is inserted and matched with the blocking wall 13, a first avoidance groove 7222 is formed between the first limiting block 7221, the first hole 722 and the first shielding insertion end 51. The inner wall of the second hole 723 facing the second shielding insertion end 61 is provided with a second limiting block 7231. The length of the second limiting block 7231 in the length direction is less than the length of the second hole 723 in the length direction. When the second groove 613 is inserted and matched with the blocking wall 13, a second avoidance groove 7232 is formed between the second limiting block 7231, the second hole 723 and the second shielding insertion end 61. This setting can prevent the edges of the second shielding insertion end 61 from cutting and wearing the inner walls of the first hole 722 and the second hole 723 when the second shielding insertion end 61 is squeezed by the second contact 611, ensuring the lap joint reliability.

[0066] As described above, it is only a partial implementation manner of the embodiments of the present application, and does not impose any form of limitation on the application. The protection scope of the embodiments of the present application is not limited thereto. Any simple modifications, equivalent changes and decorations that can be easily thought of by those skilled in the technical field of the present application within the technical scope disclosed in the embodiments of the present application should be covered within the protection scope of the embodiments of the present application.
