Description

Technical Field

[0001] The present application relates to the field of electronic communication technology, and in particular to a terminal assembly, a shielding structure and a connector. Background Art

[0002] In order to achieve electrical connection and information exchange between electronic products, connectors are often used to achieve signal connection between two or more electronic products. The existing connector interface usually has a single insulating tongue plate, and two rows of upper and lower metal signal terminals are embedded on both sides of the insulating tongue plate to achieve multi-channel signal transmission through multiple signal terminals.

[0003] Since multiple signal terminals are closely arranged on the upper and lower sides of the insulating tongue plate, the spacing between the upper and lower rows of signal terminals is small. When the signal on one or more of the signal terminals changes, unexpected voltage noise, i.e., crosstalk, will be generated on adjacent signal terminals due to electromagnetic coupling.

[0004] When crosstalk occurs, the signal waveform will be distorted. In high-speed signal transmission, this distortion may cause an increase in the signal bit error rate, thereby limiting the signal frequency that the connector can transmit. Summary of the invention

[0068] 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.

[0069] 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.

[0070] 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. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". 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.

[0071] In order to solve the technical problem in the prior art that the frequency of signals that can be transmitted by the connector is limited due to crosstalk between multiple signal terminals, the present 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 two relatively arranged terminal units, which can increase the spacing between two relatively arranged rows of terminals. By increasing the distance between the signal terminals, the coupling capacitance and mutual inductance effect between them can be reduced, thereby reducing the generation of crosstalk, which is beneficial for the connector to achieve high-frequency signal transmission.

[0072] See also Figures 1 to 27 In a first aspect, an embodiment of the present application provides a terminal assembly, including a first terminal unit and a second terminal unit, wherein the first terminal unit includes a plurality of first terminals 1 arranged side by side, each of which has a first bending section 11; the second terminal unit includes a plurality of second terminals 2 arranged side by side, each of which has a second bending section 21, such as Figures 1 to 5 shown.

[0073] The first terminal unit and the second terminal unit are arranged opposite to each other along the first direction, and the first bending section 11 and the second bending section 21 can be used to increase the spacing between the first terminal 1 and the second terminal 2 in the first direction, 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 terminal 1 and the second terminal 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 interfered during transmission, and help improve the communication quality of the connector, making it more suitable for application scenarios with high precision, high reliability and high frequency transmission.

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

[0075] In some embodiments of this application, please refer to Figure 1 and Figure 2The first bending section 11 and the second bending section 21 have the same structure, and the first bending section 11 and the second bending section 21 are oriented in opposite directions, so that the first bending section 11 and the second bending section 21 can be stamped synchronously, reducing the processing steps of the first terminal unit and the second terminal unit. The openings of the first bending section 11 and the second bending section 21 are oriented in opposite directions, and can be enclosed to form an anti-crosstalk space 3 that is symmetrical up and down. In the length direction of the first terminal 1 or the second terminal 2, the spacing change trend between the first bending section 11 and the second bending section 21 can be made relatively stable, avoiding the situation of sudden spacing changes, which is conducive to improving the anti-crosstalk effect of the anti-crosstalk space 3.

[0076] It should be noted that since the front ends of the first terminal 1 and the second terminal 2 need to be fitted with the insulating tongue plate in order to facilitate the fixation and positioning of the first terminal 1 and the second terminal 2, the distance between the first terminal 1 and the second terminal 2 needs to match the thickness of the insulating tongue plate. Therefore, it is preferred to set the anti-crosstalk space 3 at the tail ends of the first terminal unit and the second terminal unit.

[0077] In some embodiments of this application, please refer to Figures 1 to 5 The first bending section 11 is disposed at the tail end of the first terminal 1, and the second bending section 21 is disposed at the tail end of the second terminal 2, so as to avoid that when the anti-crosstalk space 3 is formed at the front end of the first terminal 1 and the second terminal 2, the fitting connection between the first terminal 1, the second terminal 2 and the insulating tongue plate is affected. Since the first bending section 11 and the second bending section 21 have the same structure, the first bending section 11 is taken as an example for structural description.

[0078] See also Figure 3 , Figure 4 and Figure 5 The first bending section 11 includes 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 respectively connected to the inclined section 111 and the first connecting section 113 at an angle; when the first direction is a vertical direction, the first bending section 11 can be made to protrude upward and the second bending section 21 can be made to protrude downward, so as to increase the spacing between the first bending section 11 and the second bending section 21 below it, thereby reducing the crosstalk between the first terminal 1 and the second terminal 2 adjacent to it. The first connecting section 113 extends along the first direction and is used to connect to the circuit board 9, so as to realize the transmission of signals between the electronic product connected to 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 to 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 to the straight section 112. The inclined section 111 can be used to gradually increase the distance between the first terminal 1 and the second terminal 2, thereby avoiding discontinuity in routing impedance caused by a sudden change in the distance between the first terminal 1 and the second terminal 2, thereby ensuring signal integrity and system stability.

[0080] In some embodiments of this application, please refer to Figure 5 The connection angle between the straight section 112 and the inclined section 111 is θ1, and θ1 is preferably an obtuse angle, which can reduce the stress at the connection between the straight section 112 and the inclined section 111, and is specifically preferably 135°±10°. The connection angle between the straight section 112 and the first connecting section 113 is θ2, and θ2 is preferably between 90° and 100°, which facilitates the first connecting section 113 to extend in the vertical direction, thereby realizing 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, and θ3=θ1 is preferably used, so that the second connecting section 12 (or the third connecting section 22) can be parallel to the straight section 112, which facilitates the shape control of the first terminal 1 or the second terminal 2.

[0081] In some embodiments of this application, please refer to Figures 1 to 5 When the first bending section 11 and the second bending section 21 are symmetrically arranged in an upper and lower direction, the anti-crosstalk space 3 is a pointed shuttle-shaped space, and the cross-section of the pointed shuttle-shaped space is approximately a pentagonal structure. By adjusting the size of the pointed shuttle-shaped space, the impedance of the terminal assembly can be adjusted, so that the impedance matching is close to consistent, and the impedance topology is basically balanced, which is beneficial to reducing the signal attenuation in the terminal assembly.

[0082] In some embodiments of this application, please refer to Figure 4 , Figure 5 , Fig.21 , Fig. 22 , Fig.25 and Fig. 27 The first connecting section 113 has a protruding portion 1131 , and the protruding portion 1131 is used to abut against a metal contact on the circuit board 9 , thereby realizing a 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 material, the first bending section 11 and the second bending section 21 have elastic deformation capabilities, and a plurality of gold fingers 92 (i.e., a plurality of metal contacts) are provided on one side of the substrate 91 of the circuit board 9. When the protrusion 1131 of the first bending section 11 or the second bending section 21 abuts against the gold finger 92, the protrusion 1131 can be tightly abutted against the gold finger 92 through the elastic force of the first bending section 11 and the second bending section 21 themselves, thereby achieving adaptive elastic contact, avoiding separation between the first connection section 113 and the gold finger 92, and avoiding connection failure between the terminal in the terminal assembly and the circuit board 9, thereby ensuring normal conduction and connection of electrical transmission and signal channels.

[0084] In some preferred embodiments of this application, please refer to Fig. 27 The protrusion 1131 has an arc-shaped guide surface on one side facing the circuit board 9, and the circuit board 9 can move smoothly along the length direction of the arc-shaped guide surface to facilitate the adjustment of the abutment position between the circuit board 9 and the terminal assembly.

[0085] In some embodiments of this application, please refer to Figure 4 A plurality of grooves are provided on the second connecting section 12 of the first terminal 1 (or on the third connecting section 22 of the second terminal 2). The shape and number of the grooves can be designed as needed, which helps prevent the terminal from loosening or falling off on the insulating tongue plate, thereby improving the reliability of the connection and ensuring that the signal can be transmitted stably and reliably.

[0086] As a specific embodiment of this application, please refer to Figure 4 The first connecting section 12 of the first terminal 1 is provided with a first groove 121 and a second groove 122 in sequence, and the first groove 121 and the second groove 122 are arranged toward the insulating tongue plate in the insulating body 8, which is beneficial 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 the accuracy of the signal waveform.

[0087] When the terminal assembly is applied to the connector, in order to protect the insulating tongue plate and the signal terminal, a metal shell 7 is provided on the outer periphery of the insulating tongue plate, which protects the insulating tongue plate and the terminal and facilitates the connection between the connector and the electronic device interface. However, the metal shell 7 easily introduces external electromagnetic interference into the signal terminal, which may damage the integrity of the signal transmission of the connector, resulting in data loss or increased bit error rate.

[0088] To solve the above problems, see Figures 1 to 27In a second aspect of an embodiment of the present application, a shielding structure is provided, comprising the terminal assembly described in the above embodiment, and further comprising a first shielding member 4, the first shielding member 4 being used to be electrically connected to a metal shell 7 of a connector, the metal shell 7 being connected to a circuit board 9 to form a grounding loop, so as to make the metal shell 7 and the first shielding member 4 have the same potential, and to prevent the metal shell 7 from introducing external electromagnetic interference into the first terminal 1 and the second terminal 2; the first shielding member 4 is arranged 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 Figures 6 to 14 As shown, the crosstalk electromagnetic waves between the first terminal 1 and the second terminal 2 can be shielded, and the crosstalk electromagnetic waves inside the anti-crosstalk space 3 can be absorbed, thereby ensuring fast, stable and balanced signal transmission.

[0089] It should be noted that the first shielding member 4 is made of metal material. In order to fix the first terminal unit, the first shielding member 4 and the second terminal unit in the connector, the first shielding member 4, the plurality of first terminals 1 and the plurality of second terminals 2 are all embedded in the insulating tongue plate of the insulating body 8. Fig. 20 , Fig.24 , Fig.25 and Fig.26 The tail end of the first shielding member 4 extends into the anti-crosstalk space 3 , and can absorb the crosstalk electromagnetic waves inside the anti-crosstalk space 3 .

[0090] In some embodiments of this application, please refer to Figures 6 to 8 The main body of the first shielding member 4 is a plate-like structure (i.e., the plate-like portion 42), which will cause a larger distance between the tail end of the first shielding member 4 and the straight section 112, resulting in poor absorption effect of the tail end of the first shielding member 4 on the crosstalk electromagnetic waves in the corresponding area of ​​the straight section 112.

[0091] In order to solve the above problems, in some embodiments of the present application, please refer to 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 spacing L1 between the tubular portion 41 and the first bending section 11, and there is a second preset spacing L2 between the tubular portion 41 and the second bending section 21, so that the distance between the metal plate of the tubular portion 41 and the first bending section 11 and / or the second bending section 21 is shortened, 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-sectional shape 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 Figures 9 to 14 As shown, as long as the crosstalk electromagnetic waves inside the anti-crosstalk space 3 can be absorbed, the purpose of the present application can be achieved.

[0093] In some preferred embodiments of this application, please refer to Fig. 9 , Fig.10 and Fig.11 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 they are concentrically arranged (that is, the cross-sectional centers coincide). At different positions on the circumference of the anti-crosstalk space 3, the spacing between the outer wall of the tubular portion 41 and the bending section plate body opposite thereto can be made the same or approximately the same, and the tubular portion 41 can evenly absorb the crosstalk electromagnetic waves at various locations on the circumference of the bending section (that is, the first bending section 11 and the second bending section 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 this application, please refer to Figures 9 to 14 The first shielding member 4 also includes a plate-like portion 42, which is embedded in the insulating tongue plate at the front end of the insulating body 8, and is used to shield and absorb the crosstalk electromagnetic waves between the second connecting section 12 and the third connecting section 22. The plate-like portion 42 is electrically connected to the tubular portion 41, so that the plate-like portion 42 and the tubular portion 41 can be connected to form a shielding whole, and then electrically connected to the metal shell 7 to achieve crosstalk electromagnetic wave shielding of the terminal assembly.

[0095] In the above embodiments, the plate-shaped portion 42 and the tubular portion 41 can be designed as separate parts and then connected into one piece by assembly, but the assembly process is relatively complicated. Fig.10 , Fig.11 , Fig.13 and Fig.14 The plate-like portion 42 and the tubular portion 41 are an integrated connection structure, and the tubular portion 41 can be made by performing multiple bending processes on the tail end of the metal plate, which is beneficial to reduce the difficulty of making the first shielding member 4 and improve the connection reliability between the plate-like portion 42 and the tubular portion 41.

[0096] In some embodiments of this application, please refer to Figures 6 to 14 The first shielding member 4 is also provided with an ear plate portion 43 for abutting against the inner wall of the metal shell 7. When the first shielding member 4 and the insulating body 8 are assembled, the ear plate portion 43 is exposed to the insulating body 8, so that the ear plate portion 43 and the inner wall of the metal shell 7 are abutted to achieve electrical connection, thereby achieving the grounding of the crosstalk electromagnetic wave. The ear plate portion 43 can be arranged on one side or both sides of the first shielding member 4, and the purpose of the present application can be achieved.

[0097] As a specific embodiment of the present application, the two ear plate portions 43 are symmetrically arranged on the left and right sides of the first shielding component 4, and can be used to achieve abutment with the inner walls on the left and right sides of the metal shell 7 and ground-conducting transmission of crosstalk electromagnetic waves, 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.

[0098] In some embodiments of this application, please refer to Fig.17 , Fig.18 , Fig.19 , Fig.24 , Fig.25 and Fig.26 The shielding structure also includes a second shielding member 5 and a third shielding member 6, which are respectively arranged on both sides of the outside of the anti-crosstalk space 3 and are used to be electrically connected to the metal shell 7 of the connector, so that the second shielding member 5, the third shielding member 6 and the metal shell 7 have the same potential, which 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), and prevent the metal shell 7 from introducing external crosstalk into the first terminal 1 and the second terminal 2.

[0099] See also Figures 1 to 27 The third aspect of the embodiment of the present application provides a shielding structure, including the terminal assembly described in the above embodiment, and also including a second shielding member 5 and a third shielding member 6, wherein the second shielding member 5 and the third shielding member 6 are respectively arranged on both sides of the outside of the anti-crosstalk space 3, and are used to be electrically connected to the metal shell 7 of the connector, so that the second shielding member 5, the third shielding member 6 and the metal shell 7 have the same potential, 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), and prevent the metal shell 7 from introducing 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 member 4 is not arranged between the first terminal unit and the second terminal unit, and the crosstalk electromagnetic waves outside the first terminal unit and the second terminal unit are shielded only by the second shielding member 5 and the third shielding member 6.

[0100] It should be noted that the second shielding member 5 and the third shielding member 6 are made of metal plates. In order to fix the second shielding member 5 and the third shielding member 6, part of the second shielding member 5 and part of the third shielding member 6 are connected to the insulating body 8. The connection method can be an embedded connection or bonding, both of which can achieve the purpose of this application.

[0101] In some embodiments of the present application, see 15 and Fig.16The second shielding member 5 is matched with the first bending section 11 to shield the tails of the multiple first terminals 1 in the upper layer from external electromagnetic waves, and the third shielding member 6 is matched with the second bending section 21 to shield the tails of the multiple second terminals 2 in the lower layer from external electromagnetic waves. The second shielding member 5 and the third shielding member 6 form a pointed shuttle-shaped bidirectional signal protection structure, which can avoid faults or inconsistencies in the signal terminal loop, completely shield external crosstalk electromagnetic waves, and ensure fast, stable and balanced signal transmission.

[0102] In some embodiments of this application, please refer to Fig.15 and Fig.16 The second shielding member 5 and the third shielding member 6 have the same structure and face in opposite directions, so as to form a pointed shuttle-shaped bidirectional signal protection structure that is symmetrical up and down. The second shielding member 5 is used as an example for structural description: the second shielding member 5 includes a first plate body 51 and a second plate body 52 connected at an angle, and the first plate body 51 extends along a first direction, and is used to shield the first connecting section 113 of the first terminal 1 or the second terminal 2, and only exposes the protrusion 1131 between the gaps of the first plate body 51 on the upper and lower sides, so as to facilitate the contact between the protrusion 1131 and the circuit board 9 while achieving the shielding of the terminal tail end. Fig.21 , Fig. 22 and Fig.23 shown.

[0103] In some embodiments of the present application, the connection angle between the second plate 52 and the first plate 51 is the same as θ2, so that the first plate 51 can achieve corresponding shielding for the first connecting section 113 and the second plate 52 can achieve corresponding shielding for the straight section 112.

[0104] In some embodiments of this application, please refer to Fig.15 and Fig.16 The second shielding member 5 further includes a third plate 53, which is embedded in the insulating body 8 and has the same inclination angle as its corresponding inclined section 111, thereby realizing corresponding shielding for the inclined section 111 in the bending section.

[0105] It should be noted that the second shielding member 5 and the third shielding member 6 in the above-mentioned embodiment of the present application are also applicable to the shielding structure provided in the second aspect of the present application. Fig.17 , Fig.18 , Fig.19 as well as Figure 23 to Figure 26As shown, it can be combined with the first shielding component 4 to form an all-round shielding structure. The internal crosstalk electromagnetic waves between the first terminal 1 and the second terminal 2 are absorbed by the first shielding component 4, and the external crosstalk electromagnetic waves between the first terminal 1 and the second terminal 2 are shielded by the second shielding component 5 and the third shielding component 6, which can significantly improve the stability of signal transmission, enhance the signal shielding effect, and improve system reliability.

[0106] See also Figures 1 to 27 , the fourth aspect of the embodiment of the present application provides a connector, including the terminal assembly described in the above embodiment. Since the tail end of the terminal assembly is provided with an anti-crosstalk space 3, the tail end spacing between the adjacent first terminal 1 and the second terminal 2 can be increased. The increase in spacing directly leads to the increase of the tail end anti-crosstalk space 3. This spatial change helps to reduce the overlap and interaction of electromagnetic fields, and the electromagnetic field interaction between differential pairs is effectively weakened, reducing the possibility of crosstalk between differential pairs; this means that when the differential pairs transmit signals, the interference from adjacent signal lines will be greatly reduced, thereby achieving the technical effect of being less prone to crosstalk, making the connector of the present application more suitable for application scenarios with high precision, high reliability and high frequency transmission, such as Figure 20 to Figure 26 shown.

[0107] In some embodiments of this application, please refer to Figure 24 to Figure 26 The connector includes 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 anti-crosstalk performance of the connector. On this basis, the second shielding member 5 and the third shielding member 6 can be respectively arranged on both sides of the outside of the anti-crosstalk space 3 to further shield the external crosstalk electromagnetic waves, which can ensure fast, stable and balanced signal transmission.

[0108] In some embodiments of the present application, the connector includes the shielding structure provided in the third aspect of the present application, and a pointed shuttle-shaped bidirectional signal protection structure can be formed by the second shielding member 5 and the third shielding member 6, which can avoid the signal terminal loop from generating a fault or inconsistency, so that the impedance topology is basically balanced and the impedance matching is close to consistency. Since the first shielding member 4 is not provided in this connector, it is only necessary to embed the second shielding member 5 and the third shielding member 6 on the upper and lower sides of the insulating body 8, which can reduce the difficulty of assembling the shielding structure in the connector and reduce the manufacturing cost of the connector.
