Abstract
Description
Technical Field
[0001] The present application relates to the field of electronic communication technology, and in particular to a shielding component and a connector. Background Art
[0002] On the insulating tongue core of the plug-in electrical connector, multiple rows of signal terminals are usually arranged for signal transmission. During high-speed signal transmission, electromagnetic interference or capacitive coupling may occur between adjacent signal terminals, resulting in a decrease in signal quality.
[0003] In the prior art, these interferences can be isolated by setting a partition shielding plate to ensure the purity and stability of the signal. However, the existing partition shielding plate is usually a single plate-shaped structure, and the signal terminal usually has a bending section according to its trend. When the signal terminal is bent away from the partition shielding plate (that is, the distance between the bending section of the signal terminal and the straight partition shielding plate is large), the shielding effect of the partition shielding plate on the signal terminal is reduced, affecting the accuracy of signal transmission in the signal terminal, resulting in the signal transmission capacity of the connector being limited, and unable to achieve reliable transmission of high-frequency and ultra-high-frequency signals. Summary of the invention
[0004] The present application provides a shielding component and a connector to solve the technical problem in the prior art that when the intermediate shielding plate is a flat plate structure, an efficient shielding effect cannot be achieved, resulting in limited signal transmission capacity of the connector.

[0021] The shielding member provided in the embodiment of the present application includes a plate-shaped portion and a tubular portion that are electrically connected. 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 distance between the shielding member and the signal terminal can be reduced by the tubular portion, which can enhance the shielding effect of the shielding member on the electromagnetic field, and efficiently realize the absorption of the crosstalk electromagnetic waves of the signal terminal, thereby improving the shielding effectiveness. This helps to reduce the impact of the external electromagnetic field on signal transmission, ensure the accuracy and stability of the signal, and thus improve the high-frequency signal transmission capability of the connector.
[0022] The connector provided in the embodiment of the present application includes the above-mentioned shielding component, which can absorb and shield the crosstalk electromagnetic waves between the upper and lower rows of signal terminals. Therefore, it naturally has the technical effect possessed by the above-mentioned shielding component. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0051] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.
[0052] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure.

Therefore, the example term "below..." may 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 herein are interpreted accordingly.
[0053] In order to solve the technical problem that the intermediate shielding plate in the prior art cannot achieve efficient shielding when it is a flat plate structure, resulting in limited signal transmission capacity of the connector, the present application provides a shielding member 1 and a connector, the shielding member 1 includes a plate-shaped portion 11 and a tubular portion 12, and the tubular portion 12 can reduce the spacing between the shielding member 1 and the signal terminal 3, which can enhance the shielding effect of the shielding member 1 on the electromagnetic field, and efficiently achieve the absorption of the crosstalk electromagnetic waves of the signal terminal 3, thereby improving the shielding effectiveness. This helps to reduce the impact of external electromagnetic fields on signal transmission, ensure the accuracy and stability of the signal, and thus improve the high-frequency signal transmission capacity of the connector.
[0054] See also Figures 1 to 17 In a first aspect, an embodiment of the present application provides a shielding member 1, comprising a plate-shaped portion 11 and a tubular portion 12, wherein 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), such as Figures 1 to 8 shown.
[0055] The tubular portion 12 is used to absorb the crosstalk electromagnetic waves around the outer periphery thereof, especially the crosstalk electromagnetic waves around the signal terminal 3 having the bent section 31. In the thickness direction of the plate-shaped portion 11, since the size of the tubular portion 12 is larger than the thickness of the plate-shaped portion 11, the distance between the shielding member 1 and the bent section 31 of the signal terminal 3 can be reduced by the tubular portion 12. Figures 9 to 12 By reducing the distance between the shielding member 1 and the signal terminal 3 , the shielding effect of the shielding member 1 on the electromagnetic field can be enhanced, thereby improving the overall shielding effectiveness of the shielding member 1 .
[0056] It should be noted that the shielding member 1 is made of metal material. When the distance between the shielding member 1 and the signal terminal 3 is reduced, the electromagnetic coupling between them will be enhanced, which means that the signal is less likely to leak from the gap between the shielding member 1 and the terminal, thereby reducing the interference of the external electromagnetic field on the signal terminal 3.
[0057] Furthermore, by reducing the distance between the shielding member 1 and the signal terminal 3 through the tubular portion 12 , the shielding effect can be improved without adding extra space, thereby optimizing space utilization and reducing manufacturing costs.
[0058] It should be noted that the location of the tubular portion 12 on the shielding member 1 can be determined according to the distribution of the bending sections 31 of the signal terminals 3 , so as to avoid contact and interference between the tubular portion 12 and the signal terminals 3 .
[0059] Since the bending section 31 of the signal terminal 3 is usually arranged at the tail end, it is preferred that the tubular portion 12 is arranged 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 side wall of the tubular portion 12 is used to reduce the distance between the tail end of the shielding member 1 and the bending section 31 of the tail end of the signal terminal 3, thereby enhancing the shielding effect of the shielding member 1 on crosstalk electromagnetic waves. Figures 9 to 12 shown.
[0060] In some embodiments of the application, see Figure 1 and Figure 3 The tubular portion 12 is arranged at one end of the plate-like portion 11, and the plate-like portion 11 and the tubular portion 12 are separately arranged, so that the plate-like portion 11 and the tubular portion 12 can be manufactured separately, and then different structural forms of the shielding member 1 are obtained by assembling different types of plate-like portions 11 with different shapes of tubular portions 12, which is conducive to the matching setting of the shielding member 1 with a variety of different shapes of signal terminals 3.
[0061] In other embodiments of the present application, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5The tubular portion 12 is arranged at one end of the plate-like portion 11. The plate-like portion 11 and the tubular portion 12 are integrated. The tubular portion 12 can be made by performing multiple bending processes on the tail end of the metal plate, which is beneficial to reduce the manufacturing difficulty of the shielding component 1 and improve the connection reliability between the plate-like portion 11 and the tubular portion 12.
[0062] In some embodiments of this application, please refer to Figures 1 to 8 The cross-sectional shape of the tubular portion 12 is polygonal, circular or elliptical. The cross-sectional shape and size of the tubular portion 12 can be set according to the impedance matching requirements. As long as the absorption of crosstalk electromagnetic waves between the signal terminals 3 (such as inside the spacing space between the upper and lower rows of signal terminals 3) can be achieved, the purpose of this application can be achieved.
[0063] It should be noted that when the cross-sectional shape of the tubular portion 12 is a polygon (i.e., the number of sides is 3 or more), it can be a regular polygon or an irregular polygon. As long as a suitable distance can be maintained between the outer wall of the tubular portion 12 and the signal terminal 3, the purpose of this application can be achieved.
[0064] In some embodiments of this application, please refer to Figure 2 and Figure 4 The cross-sectional shape of the tubular portion 12 is an axisymmetric structure, and the symmetry axis of the cross-sectional shape is parallel to the length direction of the plate-shaped portion 11, so that the distances of the tubular portion 12 extending toward both sides of the thickness direction of the plate-shaped portion 11 are equal, forming a structurally symmetrical intermediate shielding member 1. By evenly distributing the shielding material, it is possible to more effectively reduce the impact of external electromagnetic interference on the internal signal, thereby improving the overall shielding effectiveness, thereby ensuring the stability and quality of the signal.
[0065] In some embodiments of this application, please refer to Figure 1 , Figure 2 , Fig. 9 and Fig.10 The cross-section of the tubular portion 12 is a pentagon. There is a first preset spacing L1 between the tubular portion 12 and the bending section 31 of the upper row of signal terminals 3, and there is a second preset spacing L2 between the tubular portion 12 and the bending 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 bending section 31 of the upper and lower rows of signal terminals 3, and can enhance the absorption effect of the tail end of the shielding component 1 on the crosstalk electromagnetic waves inside the space between the upper and lower rows of signal terminals 3.
[0066] In other embodiments of the present application, please refer to Figure 4 , Figure 5 , Fig.11 and Fig.12The cross-section of the tubular portion 12 is rectangular, and the distance between the metal plate of the tubular portion 12 and the bending section 31 of the upper and lower rows of signal terminals 3 can also be shortened, thereby improving the absorption effect of the tail end of the shielding member 1 on the crosstalk electromagnetic waves inside the space between the upper and lower rows of signal terminals 3.
[0067] In some preferred embodiments of this application, please refer to Figure 1 , Fig. 9 and Fig.10 The cross-sectional shape of the tubular portion 12 is matched with the shape of the signal terminal 3 outside it, that is, the cross-sectional shape of the tubular portion 12 is the same as the cross-sectional shape of the spacing space enclosed by the bending sections 31 of the upper and lower rows of signal terminals 3, and they are concentrically arranged (that is, the center of the cross section coincides). At different positions on the circumference of the spacing space, the distance between the outer wall of the tubular portion 12 and the plate body of the bending section 31 opposite to it can be made the same or approximately the same, and the tubular portion 12 can evenly absorb the crosstalk electromagnetic waves at various locations on the circumference of the bending section 31, which is conducive to improving the shielding effect of the tubular portion 12 on the spacing space.
[0068] As a specific embodiment of this application, please refer to Fig. 9 and Fig.10 The signal terminal 3 includes a straight section 32 and a bent section 31. The bent sections 31 in the upper and lower rows form a pentagonal spacing space. The tubular portion 12 is arranged inside the spacing space, and the cross-sectional shape of the tubular portion 12 is the same as the cross-sectional shape of the spacing space, which can absorb the crosstalk electromagnetic waves inside the spacing space, thereby ensuring fast, stable and balanced signal transmission.
[0069] In some embodiments of this application, please refer to Figure 1 , Figure 4 , Figure 6 and Figure 7 One or more grooves are provided on the plate-like portion 11, which can change the electromagnetic field distribution of the plate-like portion 11, thereby more effectively limiting and reducing the propagation range of electromagnetic waves, helping to limit electromagnetic wave signals to a specific area, reducing electromagnetic interference, and protecting the signal terminals 3 inside the connector from the influence of external electromagnetic signals.
[0070] In some embodiments of this application, please refer to Figure 1 and Figure 6 The groove is recessed on one side or both sides of the plate-like portion 11. Since the groove is not set through the plate-like portion 11, the same or different electromagnetic field distributions can be formed on the two side surfaces of the plate-like portion 11, which helps to provide a stronger electromagnetic shielding effect in a specific area, thereby reducing electromagnetic interference in the area.
[0071] As a specific embodiment of this application, please refer to Figure 1 and Figure 6A first groove 111 and a second groove 112 are provided on the first plate surface 113 of the plate-shaped portion 11, and a plurality of first grooves 111 and second grooves 112 are arranged at the front end of the plate-shaped portion 11, so as to prevent the front end of the upper row of signal terminals 3 from being interfered by external electromagnetic signals. A plurality of third grooves 114 are provided on the second plate surface 115 of the plate-shaped portion 11, so as to prevent the front end of the lower row of signal terminals 3 from being interfered by external electromagnetic signals.
[0072] It should be noted that when the groove does not penetrate the plate-like portion 11, it will form a denser shielding layer locally, which helps to provide a stronger electromagnetic shielding effect in a specific area without causing excessive damage to the overall structure of the shielding component 1. It helps to maintain the mechanical strength and stability of the plate-like portion 11, so that it can better withstand external pressure and vibration during the plug-in process.
[0073] In other embodiments of the present application, please refer to Figure 7 The groove is arranged to pass through the plate-like portion 11, which can change the propagation path of the electromagnetic wave, making it more difficult for it to penetrate the shielding member 1, which helps to further reduce the propagation of electromagnetic interference and improve the electromagnetic compatibility of the connector.
[0074] 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.
[0075] As a specific embodiment of this application, please refer to Figure 7 The plate-like portion 11 has a plurality of fourth grooves 116, fifth grooves 117 and sixth grooves 118 that penetrate therethrough, 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 of the plate-like portion 11 to dissipate the heat inside the shielding member 1, which is conducive to the transmission of high-frequency and high-speed data.
[0076] Specifically, the fourth groove 116 is a circular through groove, which can effectively reduce high-frequency electromagnetic interference. The structural symmetry of the circular through groove helps to evenly distribute the electromagnetic field and reduce signal reflection and crosstalk. The fifth groove 117 is a rectangular through groove, which can provide better shielding effect in a specific direction, especially suitable for scenes requiring directional shielding. The sixth groove 118 is a U-shaped groove with a front opening, which provides a good shielding effect and reduces signal reflection and crosstalk, especially in a complex electromagnetic environment. By combining grooves of various shapes, different electromagnetic shielding effects can be formed in different areas of the plate-like portion 11, thereby optimizing the signal transmission performance and shielding effect of the connector.
[0077] In some embodiments of this application, please refer to Figures 1 to 8The shielding member 1 also includes a connecting portion 13 connected to the plate-like portion 11, which is used to be electrically connected to the metal shell 2 of the connector, and is connected to the circuit board 5 through the metal shell 2 to form a grounding loop, so that the potential of the metal shell 2 and the shielding member 1 is the same, thereby preventing the metal shell 2 from introducing external electromagnetic interference into the signal terminal 3.
[0078] In some embodiments of this application, please refer to Figure 6 and Figure 8 The connecting portion 13 is arranged on both sides of the plate-like portion 11, and a protruding structure 131 facing away from the plate-like portion 11 is provided on the connecting portion 13. When the metal shell 2 is clamped on the outer side 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 on both sides of the metal shell 2, thereby realizing the electrical connection between the shielding component 1 and the metal shell 2, which is beneficial to improving the connection reliability and convenience between the connecting portion 13 and the metal shell 2.
[0079] As a specific embodiment of this application, please refer to Figure 6 and Figure 8 The two connecting parts 13 are symmetrically arranged on the left and right sides of the shielding member 1, and can be used to achieve abutment with the inner walls on the left and right sides of the metal shell 2 and the ground-conducting transmission of crosstalk electromagnetic waves, blocking external electromagnetic interference from entering the signal transmission system, helping to protect the internal signals of the system from interference from external noise, and improving the accuracy and stability of signal transmission.
[0080] In some embodiments of this application, please refer to Figure 8 The protruding structure 131 has an abutting 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.
[0081] In some embodiments of this application, please refer to Figure 8 The connecting portion 13 further includes an ear plate 133, and the protruding structure 131 is protrudingly arranged on the outer surface of the ear plate 133. The connecting portion 13 and the plate-shaped portion 11 are an integrated connection structure, and the connecting portion 13 can be made by bending both sides of the metal plate, which is conducive to reducing the difficulty of making the shielding member 1 and improving the connection reliability between the plate-shaped portion 11 and the connecting portion 13.
[0082] It should be noted that, since the ear plate 133 is made of metal material, it has a certain degree of deformation ability. When the protruding structure 131 is subjected to the abutment force of the inner wall of the metal shell 2, the ear plate 133 will be deformed by the external force and generate deformation elastic force on itself, 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.
[0083] 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., which can achieve the purpose of the present application.
[0084] See also Figures 1 to 17 In a second aspect of the embodiment of the present application, a connector is provided, comprising the shielding member 1 described in the above embodiment, and also comprising a metal shell 2 and two rows of signal terminals 3, wherein the shielding member 1 is arranged between the two rows of signal terminals 3. Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.16 and Fig.17 As shown, the crosstalk electromagnetic waves between the upper and lower rows of signal terminals 3 can be shielded, and the crosstalk electromagnetic waves inside the interval space can be absorbed, thereby ensuring fast, stable and balanced signal transmission.
[0085] The shielding component 1 is electrically connected to the metal shell 2, and then connected to the circuit board 5 through the metal shell 2 to form a grounding loop, so that the potential of the metal shell 2 and the shielding component 1 are the same, thereby preventing the metal shell 2 from introducing external electromagnetic interference into the signal terminal 3, thereby preventing the integrity of the signal transmission of the connector from being damaged, reducing data loss, and reducing the bit error rate.
[0086] In some embodiments of this application, please refer to Fig.13 , Fig.14 , Fig.15 , Fig.16 and Fig.17 A shielding plate 6 is also provided on the outside of the signal terminal 3. The two shielding plates 6 are respectively arranged on both sides of the outside of the tail ends of the two rows of signal terminals 3, and are used to be electrically connected to the metal shell 2 of the connector, so that the potential of the shielding plate 6 is the same as that of the metal shell 2, which can shield the crosstalk electromagnetic waves outside the interval space, and can further improve the signal transmission effect of the connector.
[0087] It should be noted that, on the basis of absorbing the internal crosstalk electromagnetic waves between the upper and lower rows of signal terminals 3 through the shielding member 1, two shielding plates 6 can be respectively provided on both sides of the outside of the tail end of the signal terminal 3 to further shield the external crosstalk electromagnetic waves, thereby ensuring that the signal transmission of the connector is fast, smooth and balanced.
[0088] In some embodiments of this application, please refer to Fig.15 , Fig.16 and Fig.17In order to fix the shielding member 1 and the signal terminals 3 in the connector, the shielding member 1 and the plurality of signal terminals 3 are embedded in the insulating body 4. The plate-shaped portion 11 and the straight section 32 of the signal terminal 3 are embedded in the insulating tongue plate at the front end of the insulating body 4, and the tubular portion 12 and the bent section 31 of the signal terminal 3 are embedded in the insulating block 42 at the rear end of the insulating body 4, which is conducive to the assembly and layout of the shielding member 1 and the signal terminal 3 inside the connector.
[0089] It should be noted that the tubular portion 12 can also be embedded in the insulating tube 41 of the insulating body 4 to ensure that there is no electrical connection between the signal terminal 3 and the shielding member 1, which helps prevent current from flowing through an unexpected path, thereby avoiding problems such as short circuits or signal interference. It can also ensure that the signal terminal 3 is not interfered by the shielding member 1 during signal transmission, which helps maintain the integrity and accuracy of the signal, which is particularly important for high-frequency and high-speed signal transmission.
[0090] The connector of the present application can achieve ground-conducting transmission of crosstalk electromagnetic waves by abutting the shielding part 1 against the inner wall of the metal shell 2, thereby blocking external electromagnetic interference from entering the signal transmission system, helping to protect the internal signals of the system from interference from external noise, and improving the accuracy and stability of signal transmission, making the connector of the present application more suitable for application scenarios with high precision, high reliability and high frequency transmission.
