A shielding piece and a connector

Abstract

The present disclosure is related to a shielding piece and a connector. The shielding piece includes a plate portion and a tubular portion. The tubular portion is electrically connected to the plate portion. The tubular portion is used to absorb the crosstalk electromagnetic waves around it. The shielding piece absorbs and shields the crosstalk electromagnetic waves between the upper and lower rows of signal terminals through the electrically connected plate portion and tubular portion. In the thickness direction of the plate portion, since the size of the tubular portion is larger than the thickness of the plate portion, the spacing distance between the shielding piece and the signal terminal can be reduced by the tubular part, which can enhance the shielding effect of the shielding piece on the electromagnetic field. Therefore, the crosstalk electromagnetic waves of the signal terminals are efficiently absorbed, thereby improving the shielding effectiveness. This helps reduce the impact of external electromagnetic fields on signal transmission, ensures signal accuracy and stability, and thus improves the connector's high-frequency signal transmission capabilities.

Description

Technical Field

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

[0002] On the insulating tongue of a plug-in electrical connector, multiple rows of signal terminals are typically arranged to achieve signal transmission. However, in high-speed signal transmission, electromagnetic interference or capacitive coupling may occur between adjacent signal terminals, leading to a degradation in signal quality.

[0003] Existing technologies use a shielding plate to isolate interference and ensure signal purity and stability. However, existing shielding plates are typically single-plate structures, while signal terminals often have bends due to their orientation. When the signal terminal bends away from the shielding plate (i.e., the distance between the bend and the straight shielding plate is large), the shielding effect of the shielding plate on the signal terminal decreases, affecting the accuracy of signal transmission within the signal terminal. This limits the connector's signal transmission capability and prevents reliable transmission of high-frequency and ultra-high-frequency signals. Summary of the Invention

[0004] This application provides a shielding component and a connector to solve the technical problem that the existing shielding plate, when it is a flat plate structure, cannot achieve efficient shielding, resulting in limited signal transmission capability of the connector.

[0005] In a first aspect, this application provides a shielding member, comprising: a plate-shaped portion; and a tubular portion electrically connected to the plate-shaped portion, wherein the tubular portion is used to absorb crosstalk electromagnetic waves around its periphery.

[0006] Optionally, the tubular portion is disposed at one end of the plate-shaped portion, and the plate-shaped portion and the tubular portion are separately disposed; or, the tubular portion is disposed at one end of the plate-shaped portion, and the plate-shaped portion and the tubular portion are integrally disposed.

[0007] Optionally, the cross-sectional shape of the tubular portion can be polygonal, circular, or elliptical.

[0008] Optionally, the cross-sectional shape of the tubular part is an axisymmetric structure, and the axis of symmetry of the cross-sectional shape is parallel to the length direction of the plate-like part.

[0009] Optionally, the cross-sectional shape of the tubular portion is configured to match the shape of the signal terminals on its outer side.

[0010] Optionally, one or more grooves are provided on the plate-shaped portion.

[0011] Optionally, the groove is recessed on one or both sides of the plate-shaped portion.

[0012] Optionally, the groove extends through the plate-like portion.

[0013] Optionally, the shielding component also includes a connecting portion connected to the plate-shaped portion for electrical connection with the metal housing of the connector.

[0014] Optionally, the connecting portion is provided on both sides of the plate-shaped portion, and the connecting portion is provided with a protruding structure facing away from the plate-shaped portion.

[0015] Optionally, the protruding structure has an abutment surface for contacting the inner wall of the metal casing.

[0016] Secondly, this application provides a connector, including the shielding element provided in the first aspect of this application, and further including two rows of signal terminals, with the shielding element disposed between the two rows of signal terminals.

[0017] Compared with the prior art, the technical solution provided in this application has the following advantages: The shielding component provided in this application includes an electrically connected plate-shaped portion and a tubular portion. In the thickness direction of the plate-shaped portion, since the size of the tubular portion is larger than the thickness of the plate-shaped portion, the spacing between the shielding component and the signal terminal can be reduced through the tubular portion. This enhances the shielding effect of the shielding component on electromagnetic fields, effectively absorbing crosstalk electromagnetic waves from the signal terminals, thereby improving shielding effectiveness. This helps reduce the influence of external electromagnetic fields on signal transmission, ensuring signal accuracy and stability, thereby improving the high-frequency signal transmission capability of the connector.

[0018] The connector provided in this application includes the aforementioned shielding component, which can absorb and shield crosstalk electromagnetic waves between the upper and lower rows of signal terminals. Therefore, it naturally possesses the technical effects of the aforementioned shielding component. Simple Explanation of the Diagram

Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] The following disclosure provides many different embodiments or examples for implementing different structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0024] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly.

Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0025] To address the technical problem in existing technologies where the shielding plate is a flat plate structure, which fails to achieve efficient shielding and thus limits the signal transmission capability of the connector, this application provides a shielding component 1 and a connector. The shielding component 1 includes a plate-shaped portion 11 and a tubular portion 12. The tubular portion 12 reduces the distance between the shielding component 1 and the signal terminal 3, enhancing the shielding effect of the shielding component 1 against electromagnetic fields and efficiently absorbing crosstalk electromagnetic waves from the signal terminal 3, thereby improving shielding effectiveness. This helps reduce the influence of external electromagnetic fields on signal transmission, ensuring signal accuracy and stability, thereby improving the high-frequency signal transmission capability of the connector.

[0026] Please refer to Figures 1 to 17. The first aspect of this application provides a shielding member 1, which includes a plate-shaped portion 11 and a tubular portion 12. The tubular portion 12 is electrically connected to the plate-shaped portion 11 so as to transmit the crosstalk electromagnetic waves absorbed by the plate-shaped portion 11 and the tubular portion 12 to the grounding loop through other components (such as the metal housing 2), as shown in Figures 1 to 8.

[0027] The tubular portion 12 is used to absorb crosstalk electromagnetic waves around its periphery, especially crosstalk electromagnetic waves around the signal terminal 3 where the bend section 31 exists. In the thickness direction of the plate-like portion 11, since the size of the tubular portion 12 is larger than the thickness of the plate-like portion 11, the distance between the shielding member 1 and the bend section 31 of the signal terminal 3 can be reduced by the tubular portion 12, as shown in Figures 9 to 12. Reducing the distance between the shielding member 1 and the signal terminal 3 enhances the shielding effect of the shielding member 1 against electromagnetic fields, thereby improving the overall shielding effectiveness of the shielding member 1.

[0028] It should be noted that the shield 1 is made of metal. When the gap between the shield 1 and the signal terminal 3 is reduced, the electromagnetic coupling between them will be enhanced. This means that the signal is less likely to leak out from the gap between the shield 1 and the terminal, thereby reducing the interference of external electromagnetic fields on the signal terminal 3.

[0029] Furthermore, by reducing the distance between the shielding component 1 and the signal terminal 3 through the tubular portion 12, the shielding effect can be improved without increasing the additional space, thereby optimizing space utilization and reducing manufacturing costs.

[0030] It should be noted that the position of the tubular part 12 on the shielding member 1 can be determined according to the distribution of the bending section 31 of the signal terminal 3, so as to avoid contact and interference between the tubular part 12 and the signal terminal 3.

[0031] Since the bent section 31 of the signal terminal 3 is usually located at the tail end, it is preferable to place the tubular portion 12 at one end of the plate-shaped portion 11, and the axis of the tubular portion 12 is parallel to the width direction of the plate-shaped portion 11. The outer peripheral sidewall of the tubular portion 12 is used to reduce the distance between the tail end of the shielding member 1 and the bent section 31 of the tail end of the signal terminal 3, thereby enhancing the shielding effect of the shielding member 1 against crosstalk electromagnetic waves, as shown in Figures 9 to 12.

[0032] In some embodiments of the application, please refer to Figures 1 and 3. The tubular part 12 is disposed at one end of the plate-shaped part 11. The plate-shaped part 11 and the tubular part 12 are separately disposed, so that the plate-shaped part 11 and the tubular part 12 can be manufactured separately. Different structural forms of shielding 1 can be obtained by assembling plate-shaped parts 11 of different models and tubular parts 12 of different shapes. This is beneficial to realize the matching and setting of shielding 1 with signal terminals 3 of various different shapes.

[0033] In some other embodiments of this application, please refer to Figures 1, 2, 4 and 5. The tubular part 12 is disposed at one end of the plate-shaped part 11. The plate-shaped part 11 and the tubular part 12 are integrally disposed. The tubular part 12 can be made by performing multiple bending processes on the tail end of the metal plate, which helps to reduce the manufacturing difficulty of the shielding part 1 and improve the connection reliability between the plate-shaped part 11 and the tubular part 12.

[0034] In some embodiments of this application, please refer to Figures 1 to 8. The cross-sectional shape of the tubular part 12 is polygonal, circular or elliptical. The cross-sectional shape and size of the tubular part 12 can be set according to the impedance matching requirements. As long as the absorption of crosstalk electromagnetic waves between signal terminals 3 (such as the space between two rows of signal terminals 3) can be achieved, the purpose of this application can be achieved.

[0035] It should be noted that when the cross-sectional shape of the tubular part 12 is a polygon (i.e., the number of sides is 3 or more), it can be a regular polygon or a non-regular polygon. As long as a suitable distance can be maintained between the outer wall of the tubular part 12 and the signal terminal 3, the purpose of this application can be achieved.

[0036] In some embodiments of this application, please refer to Figures 2 and 4. The cross-sectional shape of the tubular part 12 is an axisymmetric structure. The axis of symmetry of the cross-sectional shape is parallel to the length direction of the plate-shaped part 11. This allows the tubular part 12 to extend equidistantly from both sides of the plate-shaped part 11 in the thickness direction, forming a symmetrical intermediate shielding member 1. By evenly distributing the shielding material, the influence of external electromagnetic interference on the internal signal can be reduced more effectively, improving the overall shielding effectiveness and thus ensuring the stability and quality of the signal.

[0037] In some embodiments of this application, please refer to Figures 1, 2, 9 and 10. The cross-section of the tubular portion 12 is pentagonal. There is a first preset distance L1 between the tubular portion 12 and the bent section 31 of the upper row of signal terminals 3, and a second preset distance L2 between the tubular portion 12 and the bent section 31 of the lower row of signal terminals 3. This shortens the distance between the metal plate of the tubular portion 12 and the bent sections 31 of the upper and lower rows of signal terminals 3, which can improve the absorption effect of the shielding member 1 on the crosstalk electromagnetic waves inside the space between the upper and lower rows of signal terminals 3.

[0038] In some other embodiments of this application, please refer to Figures 4, 5, 11 and 12. The cross-section of the tubular portion 12 is rectangular. This can also shorten the distance between the metal plate of the tubular portion 12 and the bent section 31 of the upper and lower rows of signal terminals 3, thereby improving the absorption effect of the shielding member 1 on the crosstalk electromagnetic waves inside the space between the upper and lower rows of signal terminals 3.

[0039] In some preferred embodiments of this application, as shown in Figures 1, 9, and 10, the cross-sectional shape of the tubular portion 12 is matched with the shape of the signal terminals 3 on its outer side. That is, the cross-sectional shape of the tubular portion 12 is the same as the cross-sectional shape of the space formed by the bent sections 31 of the upper and lower rows of signal terminals 3, and they are concentrically arranged (i.e., the centers of the cross-sections coincide). At different positions in the circumferential direction of the space, the distance between the outer wall of the tubular portion 12 and the plate of the bent section 31 opposite it can be the same or approximately the same. The tubular portion 12 absorbs crosstalk electromagnetic waves evenly in all directions of the circumference of the bent section 31, which helps to improve the shielding effect of the tubular portion 12 on the space.

[0040] As a specific embodiment of this application, please refer to Figures 9 and 10. The signal terminal 3 includes a straight section 32 and a bent section 31. The upper and lower rows of bent sections 31 enclose a pentagonal space. The tubular part 12 is disposed inside the space, and the cross-sectional shape of the tubular part 12 is the same as the cross-sectional shape of the space. It can absorb crosstalk electromagnetic waves inside the space, thereby ensuring fast, stable and balanced signal transmission.

[0041] In some embodiments of this application, please refer to Figures 1, 4, 6 and 7. One or more grooves are provided on the plate-shaped portion 11, which can change the electromagnetic field distribution of the plate-shaped portion 11, thereby more effectively limiting and reducing the propagation range of electromagnetic waves. This helps to confine electromagnetic wave signals to a specific area, reduce electromagnetic interference, and protect the signal terminals 3 inside the connector from the influence of external electromagnetic signals.

[0042] In some embodiments of this application, please refer to Figures 1 and 6. The groove is recessed on one side or both sides of the plate-shaped portion 11. Since the groove does not penetrate through the plate-shaped portion 11, the same or different electromagnetic field distributions can be formed on both sides of the plate-shaped portion 11, which helps to provide a stronger electromagnetic shielding effect in a specific area, thereby reducing electromagnetic interference in that area.

[0043] As a specific embodiment of this application, please refer to Figures 1 and 6. A first groove 111 and a second groove 112 are provided on the first plate surface 113 of the plate-shaped portion 11, and multiple first grooves 111 and second grooves 112 are arranged at the front end of the plate-shaped portion 11 to prevent the front end of the upper row of signal terminals 3 from being interfered with by external electromagnetic signals. Multiple third grooves 114 are provided on the second plate surface 115 of the plate-shaped portion 11 to prevent the front end of the lower row of signal terminals 3 from being interfered with by external electromagnetic signals.

[0044] It should be noted that when the groove does not penetrate the plate-shaped part 11, it will form a denser shielding layer in a local area, which helps to provide a stronger electromagnetic shielding effect in a specific area, and will not cause excessive damage to the overall structure of the shielding part 1. This helps to maintain the mechanical strength and stability of the plate-shaped part 11, so that it can better withstand external pressure and vibration during the insertion process.

[0045] In some other embodiments of this application, please refer to FIG7, the groove is provided through the plate-shaped portion 11, which can change the propagation path of electromagnetic waves, making them more difficult to penetrate the shield 1, which helps to further reduce the propagation of electromagnetic interference and improve the electromagnetic compatibility of the connector.

[0046] It should be noted that the shape, size, and position of the groove can be set according to the adjustment requirements of the electromagnetic waveform to ensure that it can achieve the expected technical effect.

[0047] As a specific embodiment of this application, please refer to FIG7. The plate-shaped portion 11 has a plurality of through-hole fourth grooves 116, fifth grooves 117 and sixth grooves 118, which not only helps to reduce the propagation of electromagnetic interference, but also allows the plurality of fourth grooves 116, fifth grooves 117 and sixth grooves 118 to serve as heat dissipation channels for the plate-shaped portion 11, dissipating the heat inside the shielding member 1, which is beneficial to realizing the transmission of high-frequency and high-speed data.

[0048] Specifically, the fourth groove 116 is a circular through-slot, which effectively reduces high-frequency electromagnetic interference. The symmetrical structure of the circular through-slot helps to evenly distribute the electromagnetic field, reducing signal reflection and crosstalk. The fifth groove 117 is a rectangular through-slot, which can provide better shielding in a specific direction, especially suitable for scenarios requiring directional shielding. The sixth groove 118 is a U-shaped groove with a front opening, providing good shielding and reducing signal reflection and crosstalk, especially performing well in complex electromagnetic environments. By combining grooves of various shapes, different electromagnetic shielding effects can be formed in different areas of the plate-shaped portion 11, thereby optimizing the signal transmission performance and shielding effect of the connector.

[0049] In some embodiments of this application, please refer to Figures 1 to 8. The shield 1 also includes a connecting portion 13 connected to the plate-shaped portion 11 for electrical connection with the metal housing 2 of the connector, and a grounding loop is formed by connecting the metal housing 2 to the circuit board 5, so that the potential of the metal housing 2 and the shield 1 are the same, and the metal housing 2 is prevented from introducing external electromagnetic interference into the signal terminal 3.

[0050] In some embodiments of this application, please refer to Figures 6 and 8. The connecting part 13 is disposed on both sides of the plate-shaped part 11, and the connecting part 13 is provided with a protruding structure 131 facing away from the plate-shaped part 11. When the metal shell 2 is snapped onto the outside of the insulating tongue core of the connector, the protruding structure 131 exposed on the insulating body 4 can directly abut against the inner walls of both sides of the metal shell 2, thereby realizing the electrical connection between the shielding part 1 and the metal shell 2, which is beneficial to improving the connection reliability and connection convenience between the connecting part 13 and the metal shell 2.

[0051] As a specific embodiment of this application, please refer to Figures 6 and 8. Two connecting parts 13 are symmetrically arranged on the left and right sides of the shield 1. They can be used to abut against the inner walls of the left and right sides of the metal shell 2 and conduct crosstalk electromagnetic waves to ground, blocking external electromagnetic interference from entering the signal transmission system. This helps to protect the internal signals of the system from external noise interference and improve the accuracy and stability of signal transmission.

[0052] In some embodiments of this application, please refer to FIG8. The protruding structure 131 has an abutment surface for contacting the inner wall of the metal shell 2, which can increase the contact area between the protruding structure 131 and the metal shell 2, help reduce the contact resistance between the protruding structure 131 and the metal shell 2, and make the transmission of electromagnetic waves at the connection smoother.

[0053] In some embodiments of this application, referring to FIG8, the connecting portion 13 further includes an ear plate 133, and a protruding structure 131 protrudes from the outer surface of the ear plate 133. The connecting portion 13 and the plate-shaped portion 11 are an integrated connecting structure. The connecting portion 13 can be made by bending both sides of the metal plate, which helps to reduce the manufacturing difficulty of the shielding component 1 and improve the connection reliability between the plate-shaped portion 11 and the connecting portion 13.

[0054] It should be noted that, since the ear plate 133 is made of metal, it has a certain deformation capability. When the protruding structure 131 is subjected to the abutting force of the inner wall of the metal shell 2, the ear plate 133 will deform under the external force and generate deformation elastic force on its own, so that the protruding structure 131 is tightly abutted against the inner wall of the metal shell 2, which can improve the tightness and reliability of the connection between the protruding structure 131 and the metal shell 2.

[0055] In some embodiments of this application, please refer to Figure 8. The ear plate 133 is also provided with a positioning structure 132 to facilitate the positioning and assembly between the shielding member 1 and the insulating body 4. The positioning structure 132 can be a positioning groove, a positioning protrusion, etc., all of which can achieve the purpose of this application.

[0056] Please refer to Figures 1 to 17. A second aspect of this application provides a connector, including the shielding member 1 described in the above embodiments, and also including a metal shell 2 and two rows of signal terminals 3. The shielding member 1 is disposed between the two rows of signal terminals 3, as shown in Figures 9, 10, 11, 12, 16 and 17. It can shield the crosstalk electromagnetic waves between the upper and lower rows of signal terminals 3 and absorb the crosstalk electromagnetic waves inside the space, thereby ensuring fast, stable and balanced signal transmission.

[0057] The shield 1 is electrically connected to the metal shell 2, and then the metal shell 2 is connected to the circuit board 5 to form a grounding loop, so that the potential of the metal shell 2 and the shield 1 is the same, avoiding the metal shell 2 from introducing external electromagnetic interference into the signal terminal 3. This can prevent damage to the integrity of the connector's signal transmission, reduce data loss, and reduce the bit error rate.

[0058] In some embodiments of this application, please refer to Figures 13, 14, 15, 16 and 17. A shielding plate 6 is also provided on the outside of the signal terminal 3. The two shielding plates 6 are respectively disposed on the outer sides of the tail ends of the two rows of signal terminals 3, and are used to electrically connect with the metal shell 2 of the connector, so that the potential of the shielding plate 6 and the metal shell 2 are the same, which can shield the crosstalk electromagnetic waves outside the space, and can further improve the signal transmission effect of the connector.

[0059] It should be noted that, based on the absorption of internal crosstalk electromagnetic waves between the upper and lower rows of signal terminals 3 by the shielding component 1, two shielding plates 6 can be set on the outer sides of the tail end of the signal terminal 3 to further shield external crosstalk electromagnetic waves, which can ensure that the signal transmission of the connector is fast, stable and balanced.

[0060] In some embodiments of this application, please refer to Figures 15, 16, and 17. To secure the shielding component 1 and the signal terminals 3 within the connector, the shielding component 1 and multiple signal terminals 3 are embedded within the insulating body 4. Specifically, the plate-shaped portion 11 and the straight section 32 of the signal terminals 3 are embedded in the insulating tongue plate at the front end of the insulating body 4, while the tubular portion 12 and the bent section 31 of the signal terminals 3 are embedded in the insulating block 42 at the rear end of the insulating body 4. This facilitates the assembly and arrangement of the shielding component 1 and the signal terminals 3 within the connector.

[0061] It should be noted that the tubular portion 12 can also be embedded in the insulating tube 41 of the insulating body 4, ensuring that there is no electrical connection between the signal terminal 3 and the shield 1. This helps prevent current from flowing through unexpected paths, thereby avoiding problems such as short circuits or signal interference. It also ensures that the signal terminal 3 is not interfered with by the shield 1 during signal transmission, which helps maintain the integrity and accuracy of the signal, and is especially important for high-frequency and high-speed signal transmission.

[0062] The connector of this application can achieve grounding transmission of crosstalk electromagnetic waves by abutting the shield 1 against the inner wall of the metal shell 2, blocking external electromagnetic interference from entering the signal transmission system, which helps to protect the internal signals of the system from external noise interference, improves the accuracy and stability of signal transmission, and makes the connector of this application more suitable for high-precision, high-reliability and high-frequency transmission application scenarios.
