Description

Technical Field

[0001] This application relates to the field of connector technology, and more particularly to a shielding component and connector for a connector. Background Technology

[0002] In modern electronic devices, the connection between the connector and the reference ground of the printed circuit board (PCB) is crucial, affecting not only signal transmission quality but also the reliability of the device. Currently, each pair of signal terminals in a connector socket has an external shielding structure, and the shielding structures of different pairs of signal terminals are connected by a common shielding ground structure. However, the reliability of the common shielding ground structure and the connection between the shielding structures is not high, increasing signal crosstalk. Summary of the Invention

[0003] The main objective of this application is to provide a shielding component and connector for a connector, which aims to reduce signal crosstalk in the connector.

[0004] To achieve the above objectives, embodiments of this application propose a shielding assembly and a connector, comprising:

[0005] The grounding connector is provided with a clearance hole; and

[0006] A plurality of terminal shielding components are provided at intervals. Each terminal shielding component includes a shielding sleeve and a grounding rod. One end of the grounding rod is connected to the shielding sleeve, and the other end of the grounding rod passes through the clearance hole. In the thickness direction of the grounding rod, the grounding rod and the wall of the clearance hole abut against each other to form a contact point.

[0007] To achieve the above objectives, this application provides a connector comprising conductive terminals, a circuit board, and a shielding assembly of the connector described above. The conductive terminals are disposed inside the shielding sleeve, and the grounding rod is connected to the circuit board.

[0008] The technical solution of this application, through the provision of terminal shielding, provides a return path and prevents electromagnetic fields from interfering with signal propagation at the signal terminals. Furthermore, a common ground connector links multiple terminal shielding components together, enabling different shielding components to achieve common ground conduction. This ensures that all signal terminals reference the same common ground standard during transmission, preventing interference between signal terminals due to inter-terminal correlation and thus reducing signal crosstalk. Moreover, the grounding rod in the terminal shielding abuts against the wall of the clearance hole in the thickness direction, ensuring stable fixation within the clearance hole. This enhances the reliability of the connection between the terminal shielding and the common ground connector, improving the uniformity of magnetic field distribution within the clearance hole, weakening the electromagnetic field intensity, and effectively reducing signal crosstalk. Additionally, eliminating the use of a common ground elastic structure saves costs, avoids poor contact between the common ground elastic structure and the circuit board, effectively reduces signal crosstalk, and improves the reliability of the connector in application.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the embodiments of this application.

[0027] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).

[0030] Furthermore, the technical solutions of the various embodiments of this application can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them.

[0031] Connectors are an important component of communication systems, providing electrical connections and serving as structural mechanical parts. With technological advancements, the application of connectors is becoming increasingly widespread, leading to more stringent requirements for their electrical performance and specifications.

[0032] As data transmission rates increase, it is usually necessary to ensure that the reference ground of the connector is connected to the reference ground of the PCB circuit board in order to achieve better crosstalk performance.

[0033] In applications where signal rate requirements are not high, such as during the 3G or 4G era, it is usually sufficient to simply crimp the grounding via of the connector to the grounding via of the circuit board.

[0034] In 5G or future 6G and 7G technologies, the requirement of a single-point contact between the PCB circuit board and the connector via a grounding eye is no longer sufficient. Therefore, each pair of signal differential terminals in the connector is typically covered with an external shielding structure, and electroplated plastic is used to connect the external shielding structures of multiple signal differential terminals to a common ground to reduce signal crosstalk.

[0035] Because the flatness of electroplated plastic is poor, and it is prone to deformation after prolonged use, poor contact between the electroplated plastic and the circuit board can occur, meaning that some areas can make contact while others cannot, thus affecting the grounding effect. Therefore, a grounding elastic structure is usually added between the connector crimping surface and the circuit board to improve the reliability of the connector-circuit board contact.

[0036] However, since connectors are typically crimped to the circuit board, the common ground resilient structure inevitably reduces the connector's holding force on the circuit board. Moreover, the common ground resilient structure is usually a thin metal sheet, which is prone to poor contact with the circuit board's reference ground after high temperatures or prolonged use, leading to increased crosstalk and eventual failure.

[0037] In view of this, the present application provides a shielding assembly for a connector, which eliminates the use of a common ground elastic structure. At the same time, the grounding rod in the terminal shielding is pressed against the wall of the clearance hole in the thickness direction, so that the grounding rod can be stably fixed in the clearance hole. The connection between the terminal shielding and the common grounding connector is more reliable, which can improve the uniformity of electromagnetic field distribution in the clearance hole, reduce the intensity of electromagnetic field, and effectively reduce signal crosstalk.

[0038] To better understand the above technical solution, the following detailed explanation is provided in conjunction with the accompanying drawings.

[0039] like Figures 1 to 7 As shown in the figure, this application embodiment proposes a shielding component for a connector, the shielding component for the connector comprising:

[0040] The common ground connector 110 has a clearance hole 111, mainly used to achieve common ground conduction of multiple terminal shields 120, reducing interference between signal terminals. Optionally, the common ground connector 110 is configured as electroplated plastic. It is understood that the main body of the common ground connector 110 is an elastic component such as plastic or rubber, and the surface of the plastic and / or the wall of the clearance hole 111 is provided with conductive metal; and

[0041] Terminal shielding components 120 are provided at intervals. Each terminal shielding component 120 includes a shielding sleeve 121 and a grounding rod 122. The shielding sleeve 121 is fitted over the signal terminal and is conductive, thereby providing a return path and preventing electromagnetic field propagation interference. One end of the grounding rod 122 is connected to the shielding sleeve 121, and the other end of the grounding rod 122 is connected to the circuit board, thereby achieving common ground conduction with the circuit board. Optionally, the shielding sleeve 121 and the grounding rod 122 are made of conductive metal. In one embodiment, the grounding rod 122 is configured as a grounding fisheye. Of course, in other embodiments, the grounding rod 122 can also have other structural forms, as long as it can achieve common ground conduction with the circuit board, which is not limited here. One end of the grounding rod 122 is connected to the shielding sleeve 121, and the other end of the grounding rod 122 passes through the clearance hole 111, so that the grounding rod 122 can pass through the common ground connector 110 and be electrically connected to the reference ground of the circuit board. To achieve common grounding among multiple terminal shields 120, the grounding rod 122 is electrically connected to the conductive metal in the common ground connector 110, or the shielding sleeve 121 is electrically connected to the conductive metal in the common ground connector 110, or both the grounding rod 122 and the shielding sleeve 121 are electrically connected to the conductive metal in the common ground connector 110; this is not limited here. Specifically, in the thickness direction of the grounding rod 122, the grounding rod 122 and the wall of the clearance hole 111 abut against each other to form a contact point. Since the grounding rod 122 needs to be press-fitted to the circuit board, a clearance hole 111 needs to be provided on the common ground connector 110 to allow the grounding rod 122 to pass through and connect to the circuit board. Considering the existence of machining tolerances, the diameter of the clearance hole 111 needs to be larger than the outer diameter of the end of the grounding rod 122 that passes through the clearance hole 111. By forming a contact point where the grounding rod 122 and the wall of the clearance hole 111 abut against each other along the thickness direction of the grounding rod 122, the contact between the grounding rod 122 and the common ground shield can be ensured in the thickness direction, thus improving the contact stability between the grounding rod 122 and the common ground shield. Specifically, the larger the contact area, the better the crosstalk prevention effect. (Refer to...) Figure 11 In this diagram, the thin solid line represents crosstalk when the contact radius is 0.05 mm, the dashed solid line represents crosstalk when the contact radius is 0.1 mm, the dotted dashed line represents crosstalk when the contact radius is 0.15 mm, and the thick solid line represents crosstalk when the contact radius is 0.2 mm.

[0042] It should be noted that crosstalk generally occurs when a signal terminal is affected by the electromagnetic field of another terminal during signal transmission. Therefore, methods to improve crosstalk typically involve increasing the distance between the affected and attacking terminals, or adding a grounding structure to direct the interfering electromagnetic field from the attacking terminal into the reference ground, thus preventing further interference to the affected terminal. However, in most cases, application scenarios and space are limited, and the distance between the attacker and victim cannot be arbitrarily increased. Therefore, it is necessary to strengthen the grounding structure to reduce crosstalk. Research and experiments have shown that the specific location for strengthening grounding depends on a detailed analysis of the electromagnetic field distribution in the space. Therefore, this application increases the contact between the grounding rod 122 and the clearance hole 111 of the common ground connector 110 in the thickness direction. (Refer to...) Figure 10 Simulation analysis after increasing the contact in the thickness direction revealed that, under the same structure, the intensity of the interfering electromagnetic field was reduced, the distribution of the electromagnetic field was more uniform, and the crosstalk was smaller.

[0043] In this embodiment, the terminal shield 120 provides a return path, preventing electromagnetic interference to the signal propagation of the signal terminals. Furthermore, the common ground connector 110 connects multiple terminal shields 120, allowing different shields to achieve common grounding. This ensures that all signal terminals reference the same common ground standard during transmission, preventing interference between signal terminals due to correlation and reducing crosstalk. Moreover, the grounding rod 122 in the terminal shield 120 abuts against the wall of the clearance hole 111 in the thickness direction, ensuring stable fixation. This makes the connection between the terminal shield 120 and the common ground connector 110 more reliable, improving the uniformity of the magnetic field distribution in the clearance hole 111, weakening the electromagnetic field intensity, and effectively reducing crosstalk. Figure 13 The solid line represents crosstalk when the grounding rod 122 contacts the common ground connector 110 along the thickness direction, and the dashed line represents crosstalk when the common ground elastic structure is removed. Furthermore, eliminating the use of the common ground elastic structure saves costs, avoids poor contact between the common ground elastic structure and the circuit board, effectively reduces signal crosstalk, and improves the reliability of the connector in application. At the same time, the common ground contact in this application does not need to directly contact the crimping area of ​​the circuit board; that is, the crimping area of ​​the circuit board can be either bright copper or not, broadening the application scenarios.

[0044] In the embodiments of this application, reference is made to Figures 2 to 5The grounding rod 122 has two first sidewalls arranged opposite each other along its thickness direction. A contact structure 130 protrudes from each first sidewall. One end of the contact structure 130 connects to the first sidewall, and the other end contacts the wall of the clearance hole 111 to form a contact point. In other words, the grounding rod 122 has two first sidewalls along its thickness direction, which are arranged opposite each other and spaced apart. At least one first sidewall has a contact structure 130 protruding from it, thus thickening a local portion of the first sidewall and pressing it against the wall of the clearance hole 111. This improves the contact reliability of the grounding rod 122 with the grounding connector 110 in the thickness direction, effectively guiding crosstalk electromagnetic fields to the reference ground of the circuit board and reducing signal crosstalk. (Refer to...) Figure 9 The solid line represents crosstalk when neither of the two surfaces of the grounding rod 122 in the thickness direction is in contact with the common ground connector 110; the dashed line represents crosstalk when one surface of the grounding rod 122 in the thickness direction is in contact with the common ground connector 110; and the dotted dashed line represents crosstalk when both surfaces of the grounding rod 122 in the thickness direction are in contact with the common ground connector 110.

[0045] In the embodiments of this application, reference is made to Figure 2 The abutment structure 130 is configured as a solid protrusion. It is understood that in one embodiment, the abutment structure 130 is configured as a solid protrusion, in which case the solid protrusion makes rigid contact with the wall of the clearance hole 111. This provides stronger support and durability, preventing the grounding rod 122 from swaying under vibration or impact conditions, and improving the contact reliability between the grounding rod 122 and the common ground connector 110. Moreover, the solid protrusion has a relatively simple shape and can be manufactured through various methods such as injection molding, casting, and machining, reducing manufacturing costs.

[0046] In the embodiments of this application, the side of the solid protrusion facing away from the grounding rod 122 is an arc surface. Compared with sharp corners or flat surfaces, arc surfaces can effectively reduce stress concentration, withstand larger periodic loads or impacts, improve contact stability, and reduce displacement caused by vibration or impact. Moreover, it can also reduce scratches on the wall of the clearance hole 111, reduce damage to the conductive metal of the wall of the clearance hole 111, and improve the reliability of the electrical connection.

[0047] In the embodiments of this application, reference is made to Figures 3 to 5 The abutment structure 130 is configured as an elastic abutment part, which tends to abut against the wall of the clearance hole 111. Thus, the elastic abutment part and the wall of the clearance hole 111 are in elastic contact. When the grounding rod 122 passes through the clearance hole 111 under external force, the elastic abutment part deforms and becomes elastic. When the external force disappears, the elastic abutment part abuts against the wall of the clearance hole 111 under the action of elasticity, improving the reliability of the contact between the grounding rod 122 and the common ground connector 110.

[0048] In the embodiments of this application, reference is made to Figure 3 The elastic abutment part is configured as a stamped hollow convex shape; refer to Figure 5 Alternatively, the elastic abutment portion may be configured as an abutment spike, with one end of the abutment spike connected to the grounding rod 122, and the other end of the abutment spike tilted and folded away from the first sidewall; see reference. Figure 4 Alternatively, the elastic contact part can be configured as an arc-shaped spring. In this way, through its own structural design or by using elastic materials, the elastic contact part can be made elastic, thereby achieving elastic contact between the grounding rod 122 and the hole wall of the avoidance hole 111, resulting in a more reliable contact effect.

[0049] In the embodiments of this application, the height of the abutment structure 130 protruding from the grounding rod 122 is H, the diameter of the clearance hole 111 along the thickness direction is R, and the outer diameter of the grounding rod 122 along the thickness direction is L. The value of H is positively correlated with the difference between R and L. Specifically, the purpose of the abutment structure 130 is to achieve contact between the grounding rod 122 and the clearance hole 111 in the thickness direction. Therefore, the height of the abutment structure 130 protruding from the grounding rod 122 in the thickness direction needs to meet the requirement of tightly abutting against the clearance hole 111. It is understood that the value of H is positively correlated with the difference between R and L; that is, the larger the difference between R and L, the larger the value of H; the smaller the difference between R and L, the smaller the value of H. Optionally, 2H ≥ (RL).

[0050] In the embodiments of this application, H = (F*L³*10⁹) / (192*E*I); where E is the elastic modulus, I is the moment of inertia of the cross section of the abutment structure 130 (I = bh³, b is the width of the abutment structure 130, h is the thickness of the abutment structure 130), F is the force of the abutment structure 130, and L is the length of the abutment structure 130. If the height of the abutment structure 130 is too large, it will generate a large positive force on the ground connector 110, which will easily damage the ground connector 110. Therefore, H = (F*L³*10⁹) / (192*E*I) can prevent the ground connector 110 from being damaged due to the excessive height of the abutment structure 130. Within this range, the positive force on the ground connector 110 can be reduced while ensuring that the contact structure 140 abuts against the wall of the clearance hole 111.

[0051] Optionally, the abutment structure 130 is made of copper alloy with an elastic modulus E of 120 GPa. The length L of the abutment structure 130 is 0.4 mm, the thickness h is 0.15 mm, the width b is 0.15 mm, the moment of inertia I is 0.0005 mm⁴, and the force F of the abutment structure 130 is between 0 and 10 N. Therefore, the height H of the abutment structure 130 can be calculated to be 0 to 0.65 mm using the formula. Of course, in other embodiments, the abutment structure 130 can also be made of other materials such as iron, and the calculation method described above can be used as a reference, which will not be detailed further.

[0052] In the embodiments of this application, the end of the grounding rod 122 away from the shielding sleeve 121 has a crimping surface, and the contact point is located near the crimping surface; that is, the contact point should be close to the crimping surface. The grounding rod 122 needs to be crimped with the reference ground of the circuit board to achieve grounding conductivity. Therefore, the closer the contact point is to the crimping surface, the more conducive it is to reliable crimping of the grounding rod 122 with the circuit board, and the smaller the crosstalk. (Refer to...) Figure 12 The dashed line represents a distance of 0.25 mm from the contact point to the crimping surface, while the solid line represents a distance of 0.05 mm. Optionally, the distance from the contact point to the crimping surface can be ≤1.25 mm, meaning that 1.25 mm, 1 mm, 0.5 mm, or 0 mm can be selected depending on the specific application scenario; no limitation is imposed here.

[0053] In the embodiments of this application, reference is made to Figure 3 Each first sidewall is provided with an abutment structure 130, and the abutment structures 130 on the two first sidewalls are staggered in the thickness direction. In this way, abutment with the wall of the clearance hole 111 can be achieved at different positions in the axial direction of the grounding rod 122, further improving the contact reliability between the grounding rod 122 and the common ground connector 110.

[0054] In the embodiments of this application, reference is made to Figure 8 The diameter of the clearance hole 111 decreases along its thickness direction away from the shielding sleeve 121, causing the outer peripheral wall of the grounding rod 122 to abut against the wall of the clearance hole 111. It is understood that the diameter of the clearance hole 111 along its thickness direction is slightly smaller than the thickness of the grounding rod 122 at the end away from the shielding sleeve 121. This ensures that the grounding rod 122 abuts against the diameter of the clearance hole 111, while facilitating one end of the grounding rod 122 to pass through the clearance hole 111 and be pressed against the circuit board. Optionally, the clearance hole 111 is a tapered hole.

[0055] In the embodiments of this application, reference is made to Figure 2 , Figure 3 as well as Figure 6The grounding rod 122 also has two opposing second sidewalls, which connect to two opposing first sidewalls and are arranged along the width direction of the grounding rod 122. A contact structure 140 is provided on the second sidewall; in the width direction of the grounding rod 122, the contact structure 140 abuts against the wall of the clearance hole 111. In this way, the grounding rod 122 can simultaneously contact the common ground connector 110 in both the width and thickness directions, further improving the reliability of the contact. The specific structure of the contact structure 140 can refer to the specific structure of the abutment structure 130, and is not limited here.

[0056] This application also proposes a connector, which includes conductive terminals, a circuit board, and a shielding assembly of the connector described above. The conductive terminals are disposed inside the shielding sleeve 121, and the grounding rod 122 is connected to the circuit board. Specifically, the specific structure of the shielding assembly of the connector refers to the above embodiments. Since this connector adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0057] The above description is merely an exemplary implementation of this application and does not limit the patent scope of the embodiments of this application. Any equivalent structural transformations made based on the technical concept of the embodiments of this application and the contents of the specification and drawings of the embodiments of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the embodiments of this application.
