[0068] In order to make the objects, 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. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the scope of protection of the present application.

[0069] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplification, the components and arrangements of the specific examples are described in the following. Of course, they are only examples and the purpose is not to limit the present application. In addition, reference numerals and / or letters can be repeated in different examples in the present application. Such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or arrangements discussed.

[0070] For the purpose of description, spatial relative terms can be used in the description to describe the relative position relationship or movement of one element or feature with respect to another element or feature as shown in the drawings, such as "inner", "outer", "inboard", "outboard", "under", "below", "over", "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 drawings. For example, if the device in the drawings is flipped over or the posture is changed or the movement state is changed, the directional indications will also change accordingly, for example: the element described as "under" or "below" another element or feature will be oriented as "above" or "above" another element or feature. Therefore, the example term "below" can include both up and down positions. The device can be additionally oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the description are interpreted accordingly.

[0071] In order to solve the technical problem that the signal frequency that can be transmitted by the connector in the prior art is limited due to crosstalk between multiple signal terminals, the application provides a terminal assembly, a shielding structure and a connector, the terminal assembly can form an anti-crosstalk space 3 through the bending sections of the two terminal units arranged opposite to each other, the spacing between the two rows of terminals arranged opposite to each other can be increased, the coupling capacitance and mutual inductance effect between the signal terminals can be reduced by increasing the distance between the signal terminals, thereby reducing the generation of crosstalk, which is conducive to the transmission of high-frequency signals by the connector.

[0072] Please refer to Figures 1 to 5 The first aspect of the embodiments of the application provides a terminal assembly, which comprises a first terminal unit and a second terminal unit, wherein the first terminal unit comprises a plurality of first terminals 1 arranged side by side, each first terminal 1 having a first bending section 11; the second terminal unit comprises a plurality of second terminals 2 arranged side by side, each second terminal 2 having a second bending section 21, as shown in Figure 1 .

[0073] The first terminal unit and the second terminal unit are arranged opposite to each other in a first direction, the spacing between the first terminals 1 and the second terminals 2 in the first direction can be increased through the first bending sections 11 and the second bending sections 21, so as to form an anti-crosstalk space 3 between the plurality of first bending sections 11 and the plurality of second bending sections 21, due to the existence of the anti-crosstalk space 3, the coupling capacitance and mutual inductance effect between the adjacent first terminals 1 and second terminals 2 can be reduced, thereby reducing the generation of crosstalk. Reducing crosstalk can enhance the integrity of the signal, ensure that the signal is not disturbed during transmission, and help to improve the communication quality of the connector, so that it is more suitable for application scenarios of high precision, high reliability and high frequency transmission.

[0074] It should be noted that the first terminals 1 and the second terminals 2 can be made by stamping process, and the bending shape and size of the first bending sections 11 and the second bending sections 21 can be designed according to the size requirements of the anti-crosstalk space 3. Since crosstalk can cause impedance matching accuracy to decrease, thereby affecting the efficiency and quality of signal transmission. The application reduces crosstalk through the anti-crosstalk space 3, which can improve the accuracy of impedance matching and ensure that the signal can be accurately matched to the expected impedance value during transmission.

[0075] In some embodiments of the application, please refer to Figure 2 and Figures 1 to 5The first bending section 11 and the second bending section 21 are opposite in direction, synchronous stamping of the first bending section 11 and the second bending section 21 can be realized, and the processing steps of the first terminal unit and the second terminal unit are reduced. The openings of the first bending section 11 and the second bending section 21 are opposite in direction, the anti-crosstalk space 3 symmetrical in up and down can be enclosed, the spacing trend between the first bending section 11 and the second bending section 21 is relatively stable in the length direction of the first terminal 1 or the second terminal 2, the condition of sudden change of spacing is avoided, and the anti-crosstalk effect of the anti-crosstalk space 3 is improved.

[0076] It should be noted that the front ends of the first terminal 1 and the second terminal 2 need to be attached to the insulating tongue plate, so as to realize the fixing and positioning of the first terminal 1 and the second terminal 2, and the spacing between the first terminal 1 and the second terminal 2 needs to match the thickness of the insulating tongue plate, therefore, the anti-crosstalk space 3 is preferably arranged at the tail end of the first terminal unit and the second terminal unit.

[0077] In some embodiments of the present application, referring to Figure 3 , the first bending section 11 is arranged at the tail end of the first terminal 1, and the second bending section 21 is arranged at the tail end of the second terminal 2, so as to avoid that the anti-crosstalk space 3 formed at the front end of the first terminal 1 and the second terminal 2 affects the attached connection of the first terminal 1, the second terminal 2 and the insulating tongue plate. Since the first bending section 11 and the second bending section 21 are the same in structure, the structure of the first bending section 11 is described as an example.

[0078] Referring to Figure 4 , Figure 5 and Figure 5 , the first bending section 11 comprises an inclined section 111, a straight section 112 and a first connecting section 113 connected in sequence, and the two ends of the straight section 112 are angularly connected with the inclined section 111 and the first connecting section 113 respectively; when the first direction is a vertical direction, the first bending section 11 can protrude upward, and the second bending section 21 can protrude downward, so as to increase the spacing between the first bending section 11 and the second bending section 21 below the first bending section 11, thereby reducing the crosstalk between the first terminal 1 and the adjacent second terminal 2. The first connecting section 113 extends along the first direction, is used for connecting with the circuit board 9, and realizes the transmission of signals between the electronic product connected with the connector and the circuit board 9.

[0079] It should be noted that the front end of the inclined section 111 of the first bending section 11 is connected with the second connecting section 12 at the front end of the first terminal 1, and the rear end of the inclined section 111 of the first bending section 11 is connected with the flat section 112. The interval between the first terminal 1 and the second terminal 2 can be gradually increased through the inclined section 111, so as to avoid the discontinuity of the wiring impedance caused by the sudden change of the interval between the first terminal 1 and the second terminal 2, and to protect the integrity of the signal and the stability of the system.

[0080] In some embodiments of the present application, referring to Figures 1 to 5 , the connection angle between the flat section 112 and the inclined section 111 is θ1, preferably the value of θ1 is obtuse angle, which can reduce the stress at the connection between the flat section 112 and the inclined section 111, and specifically preferably 135°±10°. The connection angle between the flat section 112 and the first connecting section 113 is θ2, preferably the value of θ2 is between 90° and 100°, which facilitates the first connecting section 113 to extend in the vertical direction, so as to realize the signal connection between the first connecting section 113 and the circuit board 9. The connection angle between the inclined section 111 and the second connecting section 12 is θ3, preferably θ3=θ1, which can make the second connecting section 12 (or the third connecting section 22) parallel to the flat section 112, and facilitate the shape control of the first terminal 1 or the second terminal 2.

[0081] In some embodiments of the present application, referring to Figure 4 , when the first bending section 11 and the second bending section 21 are arranged in an up-down symmetry, the anti-crosstalk space 3 is a sharp shuttle-shaped space, and the cross section of the sharp shuttle-shaped space is approximately a pentagonal structure. By adjusting the size of the sharp shuttle-shaped space, the impedance of the terminal assembly can be adjusted, so as to make the impedance matching close to consistent, and make the impedance topology basically balanced, which is beneficial to reduce the signal attenuation in the terminal assembly.

[0082] In some embodiments of the present application, referring to Figure 5 , Figure 21 , Figure 22 , Figure 25 , Figure 27 and Figure 27 , the first connecting section 113 has a protruding part 1131, which is used for abutting with the metal contact on the circuit board 9, so as to realize the signal connection between the first terminal 1 or the second terminal 2 and the circuit board 9.

[0083] It should be noted that, since the first terminal 1 and the second terminal 2 are made of metal materials, the first bending section 11 and the second bending section 21 have elastic deformation capability, and the substrate 91 side of the circuit board 9 is provided with a plurality of gold fingers 92 (i.e. a plurality of metal contacts), when the protruding part 1131 of the first bending section 11 or the second bending section 21 abuts on the gold finger 92, the protruding part 1131 can be tightly abutted on the gold finger 92 by the elastic force of the first bending section 11 and the second bending section 21 itself, and self-adaptive elastic contact can be achieved, avoiding separation between the first connecting section 113 and the gold finger 92, and avoiding connection failure between the terminals in the terminal assembly and the circuit board 9, to ensure normal conduction connection of the electrical transmission and signal channel.

[0084] In some preferred embodiments of the present application, referring to Figure 4 , the side of the protruding part 1131 facing the circuit board 9 has an arc-shaped guide surface, and the circuit board 9 can move smoothly along the length direction of the arc-shaped guide surface, so as to facilitate adjustment of the abutting position between the circuit board 9 and the terminal assembly.

[0085] In some embodiments of the present application, referring to Figure 4 , a plurality of grooves are arranged on the second connecting section 12 of the first terminal 1 (or on the third connecting section 22 of the second terminal 2), and the shape and number of the grooves can be designed as needed, which helps to prevent the terminals from loosening or falling off on the insulating tongue plate, thereby improving the connection reliability and ensuring stable and reliable transmission of signals.

[0086] As a specific embodiment of the present application, referring to Figures 1 to 27 , the first connecting section 12 of the first terminal 1 is sequentially provided with a first groove 121 and a second groove 122, and the first groove 121 and the second groove 122 are arranged towards the insulating tongue plate in the insulating body 8, which is conducive to improving the connection reliability between the second connecting section 12 and the insulating tongue plate, thereby improving the stability and reliability of signal transmission and ensuring accurate signal waveform.

[0087] When the terminal assembly is applied to a connector, in order to protect the insulating tongue plate and the signal terminal, a metal shell 7 is arranged on the outer periphery of the insulating tongue plate, which protects the insulating tongue plate and the terminal and facilitates the interface plugging of the connector and the electronic equipment. However, the metal shell 7 is easy to introduce external electromagnetic interference into the signal terminal, which will damage the integrity of the signal transmission of the connector, resulting in data loss or increased bit error rate.

[0088] In order to solve the above problems, referring to Figures 6 to 14The second aspect of this application provides a shielding structure, including the terminal assembly described in the above embodiments, and further including a first shielding member 4. The first shielding member 4 is used for electrical connection with the metal housing 7 of the connector. The metal housing 7 is connected to the circuit board 9 to form a grounding loop, so that the potential of the metal housing 7 and the first shielding member 4 are the same, preventing the metal housing 7 from introducing external electromagnetic interference into the first terminal 1 and the second terminal 2. The first shielding member 4 is disposed between the first terminal unit and the second terminal unit, and a portion of the first shielding member 4 extends into the interior of the anti-crosstalk space 3, such as... Figure 20 As shown, it can shield the crosstalk electromagnetic waves between the first terminal 1 and the second terminal 2, and absorb the crosstalk electromagnetic waves inside the anti-crosstalk space 3, thereby ensuring fast, stable and balanced signal transmission.

[0089] It should be noted that the first shielding member 4 is made of metal. To secure the first terminal unit, the first shielding member 4, and the second terminal unit within the connector, the first shielding member 4, multiple first terminals 1, and multiple second terminals 2 are all embedded in the insulating tongue plate of the insulating body 8, as shown below. Figure 24 , Figure 25 , Figure 26 and Figures 6 to 8 As shown. The tail end of the first shield 4 extends into the anti-crosstalk space 3, which can absorb the crosstalk electromagnetic waves inside the anti-crosstalk space 3.

[0090] In some embodiments of this application, please refer to Figures 9 to 14 The main body of the first shielding component 4 is a plate-shaped structure (i.e., plate-shaped part 42), which makes the distance between the tail end of the first shielding component 4 and the straight section 112 larger, resulting in a poor absorption effect of the tail end of the first shielding component 4 on the crosstalk electromagnetic waves in the corresponding area of ​​the straight section 112.

[0091] To address the aforementioned issues, please refer to some embodiments of this application. Figures 9 to 14 The first shielding component 4 includes a tubular portion 41 located inside the anti-crosstalk space 3. There is a first preset distance L1 between the tubular portion 41 and the first bending section 11, and a second preset distance L2 between the tubular portion 41 and the second bending section 21. This shortens the distance between the metal plate of the tubular portion 41 and the first bending section 11 and / or the second bending section 21, thereby improving the absorption effect of the tail end of the first shielding component 4 on the crosstalk electromagnetic waves inside the anti-crosstalk space 3.

[0092] It should be noted that the cross-sectional shape and size of the tubular portion 41 can be set according to the impedance matching requirements. The cross-section of the tubular portion 41 can be rectangular, elliptical, or polygonal, etc. The tubular portion 41 can also be embedded in the insulating tube 81 of the insulating body 8, such as... Figure 9 As shown, as long as the absorption of crosstalk electromagnetic waves inside the anti-crosstalk space 3 can be achieved, the purpose of this application can be achieved.

[0093] In some preferred embodiments of the present application, referring to Figure 10 , Figure 11 and Figures 9 to 14 , the shape of the tubular portion 41 is matched with the shape of the anti-crosstalk space 3, that is, the cross-sectional shape of the tubular portion 41 is the same as the cross-sectional shape of the anti-crosstalk space 3, and is concentrically arranged (that is, the cross-sectional centers coincide). At different positions in the circumferential direction of the anti-crosstalk space 3, the outer wall of the tubular portion 41 can be arranged at the same or approximately the same distance from the opposite bent segment plate body, so that the tubular portion 41 can uniformly absorb the crosstalk electromagnetic waves at each position in the circumferential direction of the bent segment (that is, the first bent segment 11 and the second bent segment 21), which is conducive to improving the shielding effect of the tubular portion 41 on the anti-crosstalk space 3.

[0094] In some embodiments of the present application, referring to Figure 10 , the first shielding member 4 further comprises a plate-shaped portion 42 embedded in the insulating tongue plate at the front end of the insulating main body 8, for shielding and absorbing crosstalk electromagnetic waves between the second connecting segment 12 and the third connecting segment 22. The plate-shaped portion 42 is electrically connected with the tubular portion 41, so that the plate-shaped portion 42 and the tubular portion 41 are connected in one shielding whole, and then are electrically connected with the metal shell 7, realizing the shielding of crosstalk electromagnetic waves on the terminal assembly.

[0095] In the above embodiments, the plate-shaped portion 42 and the tubular portion 41 can be designed in a split type and then assembled into one body, but the assembly process is relatively complicated. Therefore, in some preferred embodiments of the present application, referring to Figure 11 , Figure 13 , Figure 14 and Figures 6 to 14 , the plate-shaped portion 42 and the tubular portion 41 are connected in an integrated structure, and the tubular portion 41 can be made by a multi-bending process on the tail end of the metal plate body, which is conducive to reducing the manufacturing difficulty of the first shielding member 4 and improving the connection reliability between the plate-shaped portion 42 and the tubular portion 41.

[0096] In some embodiments of the present application, referring to Figure 17 , the first shielding member 4 further comprises an ear plate portion 43 for abutting against the inner wall of the metal shell 7. When assembling the first shielding member 4 and the insulating main body 8, the ear plate portion 43 is exposed outside the insulating main body 8, so as to realize the electrical connection between the ear plate portion 43 and the inner wall of the metal shell 7, and thus realize the ground of the crosstalk electromagnetic waves. The ear plate portion 43 can be arranged on one side or both sides of the first shielding member 4, and both can achieve the purpose of the present application.

[0097] As a specific embodiment of the present application, two ear plate parts 43 are symmetrically arranged on the left and right sides of the first shielding part 4, which can be used to realize abutment with the inner walls on the left and right sides of the metal shell 7 and to realize ground transmission of crosstalk electromagnetic waves, block external electromagnetic interference from entering the signal transmission system, help to protect the internal signals of the system from external noise interference, and improve the accuracy and stability of signal transmission.

[0098] In some embodiments of the present application, referring to Figure 18 、 Figure 19 、 Figure 24 、 Figure 25 、 Figure 26 and Figures 1 to 27 , the shielding structure further comprises a second shielding part 5 and a third shielding part 6, which are respectively arranged on the outer sides of the anti-crosstalk space 3, and are used to be electrically connected with the metal shell 7 of the connector, so that the second shielding part 5 and the third shielding part 6 have the same potential as the metal shell 7, and can shield the crosstalk electromagnetic waves outside the anti-crosstalk space 3 (i.e. outside the first bending section 11 and the second bending section 21), avoiding the metal shell 7 from leading external crosstalk into the first terminal 1 and the second terminal 2.

[0099] Referring to Figure 16 , the third aspect of the embodiments of the present application provides a shielding structure, which comprises the terminal assembly described in the above embodiments, and further comprises a second shielding part 5 and a third shielding part 6, which are respectively arranged on the outer sides of the anti-crosstalk space 3, and are used to be electrically connected with the metal shell 7 of the connector, so that the second shielding part 5 and the third shielding part 6 have the same potential as the metal shell 7, and can shield the crosstalk electromagnetic waves outside the anti-crosstalk space 3 (i.e. outside the first bending section 11 and the second bending section 21), avoiding the metal shell 7 from leading external crosstalk into the first terminal 1 and the second terminal 2. The difference between this shielding structure and the shielding structure provided in the second aspect of the present application is that the first shielding part 4 is not arranged between the first terminal unit and the second terminal unit, and only the second shielding part 5 and the third shielding part 6 are used to shield the crosstalk electromagnetic waves outside the first terminal unit and the second terminal unit.

[0100] It should be noted that the second shielding part 5 and the third shielding part 6 are made of a metal plate body, and in order to fix the second shielding part 5 and the third shielding part 6, part of the second shielding part 5 and part of the third shielding part 6 are connected with the insulating main body 8, and the connection mode can be embedded connection or adhesion, which can achieve the purpose of the present application.

[0101] In some embodiments of the present application, referring to 15 and Figure 15The second shielding member 5 is arranged in matching with the first bending section 11, and is used for shielding the tail of the plurality of first terminals 1 in the upper layer from external electromagnetic waves. The third shielding member 6 is arranged in matching with the second bending section 21, and is used for shielding the tail of the plurality of second terminals 2 in the lower layer from external electromagnetic waves. The sharp-pen-shaped bidirectional signal protection structure is formed by the combination of the second shielding member 5 and the third shielding member 6, so that the fault or inconsistency of the signal terminal loop can be avoided, the external crosstalk electromagnetic waves can be completely shielded, and the signal transmission can be ensured to be fast, smooth and balanced.

[0102] In some embodiments of the present application, referring to Figure 16 and Figure 21 , the second shielding member 5 and the third shielding member 6 are the same in structure and are opposite in direction, and can form a sharp-pen-shaped bidirectional signal protection structure which is symmetrical upward and downward. Taking the second shielding member 5 as an example, the structure is described as follows: the second shielding member 5 includes a first plate body 51 and a second plate body 52 which are connected at an angle. The first plate body 51 extends along a first direction, and is used for shielding the first connecting section 113 of the first terminal 1 or the second terminal 2. Only the protruding part 1131 is exposed between the gaps of the first plate body 51 on the upper and lower sides. The shielding of the tail of the terminal is realized, and the abutment between the protruding part 1131 and the circuit board 9 is facilitated, as shown in Figure 22 , Figure 23 and Figure 15 .

[0103] In some embodiments of the present application, the connecting angle between the second plate body 52 and the first plate body 51 is the same as θ2, so that the first plate body 51 can shield the first connecting section 113, and the second plate body 52 can shield the flat section 112.

[0104] In some embodiments of the present application, referring to Figure 16 and Figure 17 , the second shielding member 5 further includes a third plate body 53. The third plate body 53 is embedded in the insulating body 8, and the inclination angle of the third plate body 53 and the corresponding inclined section 111 is the same, so that the inclined section 111 in the bending section can be shielded.

[0105] It should be noted that the second shielding member 5 and the third shielding member 6 in the above embodiments of the present application are also applicable to the shielding structure provided in the second aspect of the present application, as shown in Figure 18 , Figure 19 , Figures 23 to 26 and Figures 1 to 27As shown, the first shielding member 4, the second shielding member 5 and the third shielding member 6 can be combined to form a full-coverage shielding structure, the internal crosstalk electromagnetic waves between the first terminal 1 and the second terminal 2 are absorbed by the first shielding member 4, and the external crosstalk electromagnetic waves of the first terminal 1 and the second terminal 2 are shielded by the second shielding member 5 and the third shielding member 6, which can significantly improve the stability of signal transmission, enhance the signal shielding effect, and improve the system reliability.

[0106] As shown in Figures 20 to 26 , the fourth aspect of the embodiment of the present application provides a connector comprising the terminal assembly described in the above embodiments. Since the tail end of the terminal assembly is provided with the crosstalk prevention space 3, the tail end spacing of the adjacent first terminal 1 and the second terminal 2 can be increased, and the increase of the spacing directly leads to the increase of the tail end crosstalk prevention space 3. Such a change in space helps to reduce the overlap and interaction of electromagnetic fields, and the electromagnetic field interaction between the differential pairs is effectively weakened, reducing the possibility of crosstalk between the differential pairs. This means that the interference of the differential pairs by the adjacent signal lines during signal transmission will be greatly reduced, thereby achieving the technical effect of being less susceptible to crosstalk, making the connector of the present application more suitable for high-precision, high-reliability and high-frequency transmission application scenarios, such as Figures 24 to 26 As shown.

[0107] In some embodiments of the present application, as shown in ​ , the connector comprises the shielding structure provided by the second aspect of the present application, and the internal crosstalk electromagnetic waves between the first terminal 1 and the second terminal 2 can be absorbed by the first shielding member 4, which can further improve the crosstalk prevention performance of the connector. On this basis, the second shielding member 5 and the third shielding member 6 can be respectively arranged on the outer sides of the crosstalk prevention space 3 to further shield the external crosstalk electromagnetic waves, which can ensure fast, smooth and balanced signal transmission.

[0108] In some embodiments of the present application, the connector comprises the shielding structure provided by the third aspect of the present application, and the second shielding member 5 and the third shielding member 6 can form a sharp shuttle-shaped bidirectional signal protection structure, which can avoid the generation of faults or inconsistencies in the signal terminal loop, so that the impedance topology is basically balanced and the impedance matching is close to consistent. Since the first shielding member 4 is not provided in this connector, the second shielding member 5 and the third shielding member 6 are only embedded on the upper and lower sides of the insulating body 8, which can reduce the assembly difficulty of the shielding structure in the connector and reduce the manufacturing cost of the connector.
