[0050] In order to make the purpose, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the 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 of the present application.

For the purpose of simplicity, the elements and settings of particular examples in the following description will be described. Of course, they are only examples and are not intended to limit the present application.

[0053] To solve the technical problem that the diaphragm shielding plate in the prior art cannot achieve high-efficiency shielding effect when it is in a flat plate structure, resulting in limited signal transmission capability 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. The tubular portion 12 can reduce the spacing distance between the shielding member 1 and the signal terminal 3, and can enhance the shielding effect of the shielding member 1 on the electromagnetic field, efficiently realizing the absorption of crosstalk electromagnetic waves of the signal terminal 3, thereby improving the shielding efficiency. This helps to reduce the influence of external electromagnetic field on signal transmission, ensures the accuracy and stability of the signal, and thus improves the high-frequency signal transmission capability of the connector.
[0054] Please refer to Figures 1 to 17 The first aspect of the embodiments of the present 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 with 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 ground loop through other components (such as a metal shell 2), as shown in Figures 1 to 8 .
[0055] The tubular portion 12 is used to absorb the crosstalk electromagnetic wave around the outer periphery of the signal terminal 3, especially the crosstalk electromagnetic wave around the bending section 31 of the signal terminal 3. In the thickness direction of the plate-shaped portion 11, the size of the tubular portion 12 is greater than the thickness size of the plate-shaped portion 11, so that the distance between the shielding member 1 and the bending 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 can enhance the shielding effect of the shielding member 1 on the electromagnetic field, thereby improving the overall shielding performance of the shielding member 1.
[0056] It should be noted that the shielding member 1 is made of a metal material, and when the distance between the shielding member 1 and the signal terminal 3 is reduced, the electromagnetic coupling effect between them will be enhanced, which means that the signal is less likely to leak out 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] And 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 increasing additional space, thereby optimizing the space utilization and reducing the manufacturing cost.
[0058] It should be noted that the setting position of the tubular portion 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 portion 12 and the signal terminal 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, and to enhance the shielding effect of the shielding member 1 on the crosstalk electromagnetic wave, as shown in Figures 9 to 12 .
[0060] In some embodiments of the application, please refer to Figure 1 and Figure 3 , the tubular portion 12 is arranged at one end of the plate-shaped portion 11, and the plate-shaped portion 11 and the tubular portion 12 are arranged in a split type, so that the plate-shaped portion 11 and the tubular portion 12 can be manufactured separately, and then different types of plate-shaped portions 11 and different shapes of tubular portions 12 are assembled to obtain shielding members 1 with different structural forms, which is conducive to the matching arrangement of the shielding member 1 with a plurality of signal terminals 3 with different shapes.
[0061] In some embodiments of the application, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5The tubular part 12 is arranged at one end of the plate-shaped part 11, and the plate-shaped part 11 and the tubular part 12 are integrally arranged. The tubular part 12 can be manufactured by performing a plurality of bending processes on the tail end of the metal plate body, which is conducive to reducing the manufacturing difficulty of the shielding part 1 and improving the connection reliability between the plate-shaped part 11 and the tubular part 12.
[0062] In some embodiments of the present application, referring 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 requirement of impedance matching, as long as the absorption of crosstalk electromagnetic waves between the signal terminals 3 (such as the space between the upper and lower rows of signal terminals 3) can be achieved, the purpose of the present application can be achieved.
[0063] It should be noted that when the cross-sectional shape of the tubular part 12 is polygonal (i.e. the number of sides is more than 3), it can be a regular polygon or an irregular polygon, as long as the outer wall of the tubular part 12 can maintain an appropriate distance with the signal terminals 3, the purpose of the present application can be achieved.
[0064] In some embodiments of the present application, referring to Figure 2 and Figure 4 The cross-sectional shape of the tubular part 12 is an axisymmetric structure, and the symmetry axis of the cross-sectional shape is parallel to the length direction of the plate-shaped part 11, so that the tubular part 12 can extend to both sides of the thickness direction of the plate-shaped part 11 with equal distance, forming a structure-symmetrical partition shielding part 1. By evenly distributing the shielding material, the influence of external electromagnetic interference on the internal signal can be more effectively reduced, the overall shielding effectiveness is improved, and the stability and quality of the signal are ensured.
[0065] In some embodiments of the present application, referring to Figure 1 , Figure 2 , Figure 9 and Figure 10 The cross-section of the tubular part 12 is pentagonal, and the tubular part 12 and the bent section 31 of the upper row of signal terminals 3 have a first preset distance L1, and the tubular part 12 and the bent section 31 of the lower row of signal terminals 3 have a second preset distance L2. The distance between the metal plate of the tubular part 12 and the bent section 31 of the upper and lower rows of signal terminals 3 is shortened, which can improve the absorption effect of the tail end of the shielding part 1 on the crosstalk electromagnetic waves in the space between the upper and lower rows of signal terminals 3.
[0066] In some embodiments of the present application, referring to Figure 4 , Figure 5 , Figure 11 and Figure 12, the cross section of the tubular part 12 is rectangular, and the distance between the metal plate of the tubular part 12 and the bent sections 31 of the signal terminals 3 in the upper and lower rows can be shortened, so that the tail end of the shielding part 1 can improve the absorption effect of the crosstalk electromagnetic waves in the space between the signal terminals 3 in the upper and lower rows.
[0067] In some preferred embodiments of the present application, please refer to Figure 1 , Figure 9 and Figure 10 , the cross section shape of the tubular part 12 is matched with the shape of the signal terminals 3 outside, that is, the cross section shape of the tubular part 12 is the same as the cross section shape of the space enclosed by the bent sections 31 of the signal terminals 3 in the upper and lower rows, and is concentrically arranged (that is, the cross section centers coincide). At different positions in the circumferential direction of the space, the distance between the outer wall of the tubular part 12 and the plate body of the opposite bent section 31 can be the same or approximately the same, and the tubular part 12 can uniformly absorb crosstalk electromagnetic waves at different positions in the circumferential direction of the bent section 31, which is conducive to improving the shielding effect of the tubular part 12 on the space.
[0068] As a specific embodiment of the present application, please refer to Figure 9 and Figure 10 , the signal terminal 3 includes a flat section 32 and a bent section 31, and the bent sections 31 in the upper and lower rows enclose a pentagonal space, and the tubular part 12 is arranged inside the space, and the cross section shape of the tubular part 12 is the same as the cross section shape of the space, which can absorb the crosstalk electromagnetic waves in the space, so as to ensure the fast, smooth and balanced signal transmission.
[0069] In some embodiments of the present application, please refer to Figure 1 , Figure 4 , Figure 6 and Figure 7 , one or more grooves are arranged on the plate-shaped part 11, which can change the electromagnetic field distribution of the plate-shaped part 11, so as to more effectively limit and reduce the propagation range of electromagnetic waves, help to limit the electromagnetic wave signals in a specific area, reduce electromagnetic interference, and protect the signal terminals 3 inside the connector from the influence of external electromagnetic signals.
[0070] In some embodiments of the present application, please refer to Figure 1 and Figure 6 , the grooves are recessed on one side of the plate-shaped part 11 or on both sides of the plate-shaped part 11. Since the grooves are not arranged through the plate-shaped part 11, the same or different electromagnetic field distributions can be formed on both sides of the plate-shaped part 11, which helps to provide stronger electromagnetic shielding effect in a specific area, so as to reduce electromagnetic interference in the area.
[0071] As a specific embodiment of the present application, please refer to Figure 1 and Figure 6The first recess 111 and the second recess 112 are arranged on the first plate surface 113 of the plate-shaped portion 11, and a plurality of the first recess 111 and the second recess 112 are arranged at the front end of the plate-shaped portion 11, so that the front end of the upper row of signal terminals 3 is prevented from being interfered by external electromagnetic signals. A plurality of third recesses 114 are arranged on the second plate surface 115 of the plate-shaped portion 11, so that the front end of the lower row of signal terminals 3 is prevented from being interfered by external electromagnetic signals.
[0072] It should be noted that when the recess does not penetrate the plate-shaped portion 11, it will form a more dense shielding layer in a local area, which helps to provide stronger electromagnetic shielding effect in a specific area, and will not cause excessive damage to the overall structure of the shielding member 1, which helps to maintain the mechanical strength and stability of the plate-shaped portion 11, so that it can better withstand external pressure and vibration during plugging.
[0073] In some other embodiments of the present application, please refer to Figure 7 The recess penetrates the plate-shaped portion 11, which can change the propagation path of the electromagnetic wave, making it more difficult 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 recess can be set according to the adjustment requirements of the electromagnetic wave form to ensure that it can achieve the expected technical effect.
[0075] As a specific embodiment of the present application, please refer to Figure 7 The plate-shaped portion 11 has a plurality of fourth recesses 116, fifth recesses 117 and sixth recesses 118 arranged therethrough, which not only helps to reduce the propagation of electromagnetic interference, but also can be used as heat dissipation channels of the plate-shaped portion 11 to dissipate the heat inside the shielding member 1, which helps to realize high-frequency and high-speed data transmission.
[0076] Specifically, the fourth recess 116 is a circular through slot, which can effectively reduce high-frequency electromagnetic interference, and the structural symmetry of the circular through slot helps to uniformly distribute the electromagnetic field and reduce signal reflection and crosstalk; the fifth recess 117 is a rectangular through slot, which can provide better shielding effect in a specific direction, especially suitable for scenarios requiring directional shielding. The sixth recess 118 is a U-shaped slot with an open front end, which provides good shielding effect and reduces signal reflection and crosstalk, especially in complex electromagnetic environments; by combining a plurality of recesses with different 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.
[0077] In some embodiments of the present application, please refer to Figures 1 to 8The shielding member 1 further comprises a connecting portion 13 connected to the plate-shaped portion 11, which is electrically connected to the metal shell 2 of the connector and forms a grounding loop with the circuit board 5 through the metal shell 2, so that the metal shell 2 has the same potential as the shielding member 1, thereby avoiding the metal shell 2 from introducing external electromagnetic interference into the signal terminal 3.
[0078] In some embodiments of the present application, referring to Figure 6 and Figure 8 The connecting portion 13 is arranged on both sides of the plate-shaped portion 11, and the connecting portion 13 is provided with a protruding structure 131 facing away from the plate-shaped portion 11. When the metal shell 2 is clamped on the outside of the insulating tongue core of the connector, the protruding structure 131 exposed on the insulating body 4 can directly abut on the inner walls of both sides of the metal shell 2, thereby realizing the electrical connection between the shielding member 1 and the metal shell 2, and facilitating the connection reliability and convenience between the connecting portion 13 and the metal shell 2.
[0079] As a specific embodiment of the present application, referring to Figure 6 and Figure 8 The two connecting portions 13 are symmetrically arranged on the left and right sides of the shielding member 1, which can be used to abut on the inner walls of the left and right sides of the metal shell 2 and to conduct and transmit the crosstalk electromagnetic waves, thereby blocking the external electromagnetic interference from entering the signal transmission system, helping to protect the internal signals from the interference of external noise, and improving the accuracy and stability of signal transmission.
[0080] In some embodiments of the present application, referring 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, thereby reducing the contact resistance between the protruding structure 131 and the metal shell 2 and making the transmission of electromagnetic waves at the connection smoother.
[0081] In some embodiments of the present application, referring to Figure 8 The connecting portion 13 further comprises 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 in an integrated connection structure, which can be manufactured by bending the two sides of the metal plate body to form the connecting portion 13, thereby facilitating the manufacturing difficulty of 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 the ear plate 133 is made of metal material and has a certain deformation ability. When the protruding structure 131 is abutted by the inner wall of the metal shell 2, the ear plate 133 will be deformed by external force to generate a deformation elastic force on itself, so that the protruding structure 131 is tightly abutted on the inner wall of the metal shell 2, thereby improving the connection tightness and reliability between the protruding structure 131 and the metal shell 2.
[0083] In some embodiments of the present application, referring to Figure 8 , the ear plate 133 is further provided with a positioning structure 132, so as to facilitate the positioning assembly between the shielding member 1 and the insulating main body 4. The positioning structure 132 can be a positioning groove, a positioning protrusion or the like, and all of them can achieve the purpose of the present application.
[0084] Referring to Figures 1 to 17 , the second aspect of the embodiments of the present application provides a connector, which comprises the shielding member 1 described in the above embodiments, further comprises a metal shell 2 and two rows of signal terminals 3, and the shielding member 1 is arranged between the two rows of signal terminals 3, as shown in Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 16 and Figure 17 , the crosstalk electromagnetic waves between the upper and lower two rows of signal terminals 3 can be shielded, and the crosstalk electromagnetic waves inside the interval space can be absorbed, so as to ensure the fast, smooth and balanced signal transmission.
[0085] The shielding member 1 is electrically connected with the metal shell 2, and then connected with the circuit board 5 through the metal shell 2 to form a grounding loop, so as to make the potential of the metal shell 2 and the shielding member 1 the same, avoid the metal shell 2 from leading external electromagnetic interference into the signal terminals 3, avoid the integrity of the signal transmission of the connector from being damaged, reduce the data loss and reduce the bit error rate.
[0086] In some embodiments of the present application, referring to Figure 13 、 Figure 14 、 Figure 15 、 Figure 16 and Figure 17 , the outer side of the signal terminal 3 is further provided with a shielding plate 6, and two shielding plates 6 are respectively arranged on the outer sides of the tail ends of the two rows of signal terminals 3, which are used to be electrically connected with the metal shell 2 of the connector, so that the potential of the shielding plate 6 and the metal shell 2 is the same, and the crosstalk electromagnetic waves outside the interval space can be shielded, which 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 two rows of signal terminals 3 by the shielding member 1, two shielding plates 6 can be respectively arranged on the outer sides of the tail ends of the signal terminals 3, so as to further shield the external crosstalk electromagnetic waves, and ensure the fast, smooth and balanced signal transmission of the connector.
[0088] In some embodiments of the present application, referring to Figure 15 、 Figure 16 and Figure 17In order to realize the fixation of 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. Among them, the plate-shaped part 11 and the flat 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 part 12 and the bent section 31 of the signal terminal 3 are embedded in the insulating block 42 at the tail end of the insulating body 4, which is beneficial to realize the assembly and layout of the shielding member 1 and the signal terminals 3 in the connector.
[0089] It should be noted that the tubular part 12 can also be embedded in the insulating tube 41 of the insulating body 4, which can ensure that the signal terminal 3 and the shielding member 1 are not electrically connected, which is helpful to prevent current from flowing through unintended paths, thereby avoiding problems such as short circuit or signal interference. It can also ensure that the signal terminal 3 is not interfered by the shielding member 1 during signal transmission, which is helpful to 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 realize the ground transmission of crosstalk electromagnetic waves by the abutment of the shielding member 1 and the inner wall of the metal shell 2, block the external electromagnetic interference from entering the signal transmission system, which is helpful to protect the internal signal of the system from the interference of external noise, improve the accuracy and stability of signal transmission, and make the connector of the present application more suitable for application scenarios of high precision, high reliability and high frequency transmission.
