Description

Technical Field

[0001] This application relates to the field of electrical connector technology, and more particularly to a lead assembly, connector, and electronic system. Background Technology

[0002] Connectors are widely used in motherboards, laptops, and other computing devices. They are used to connect compact, high-performance electronic components such as NVMe (Non-Volatile Memory Express) storage media, SATA (Serial Advanced Technology Attachment) solid-state drives, Wi-Fi (Wireless Fidelity) modules, and Bluetooth modules.

[0003] In related technologies, multiple electronic components of an electronic system are electrically connected via connectors, making the electronic system smaller, faster, and more complex overall. These changes mean that the number of circuits in an electronic system within a fixed area has increased significantly, and current electronic systems transfer more data between daughter cards, thus requiring new connectors that can achieve higher speeds, higher density, and handle more data than previous connectors.

[0004] One of the challenges in manufacturing connectors for higher speeds, higher densities, and handling more data is that the signal conductive elements within the connector are very close together, leading to electrical interference between adjacent signal conductive elements. In related technologies, grounding terminals are typically placed between adjacent signal conductive elements to reduce this interference. However, this method offers poor shielding and is insufficient to meet the requirements of current connectors. Utility Model Content

[0067] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0068] Figure 1 This diagram shows a schematic representation of the lead assembly 100 according to an embodiment of the present application. Figure 2 This diagram shows a structural schematic of the first terminal module 110 according to an embodiment of this application. Figure 3 This diagram shows a structural schematic of the first signal conductive element 111 according to an embodiment of this application. Figure 4 This diagram shows a structural schematic of the conductive housing 120 according to an embodiment of the present application. Figure 5 A schematic diagram of the conductive housing 120 according to an embodiment of this application is shown. See also: Figures 1 to 5This application provides a lead assembly 100, which includes a conductive housing 120 and a plurality of first terminal modules 110.

[0069] In some examples, the conductive housing 120 can be made of a metallic material. Furthermore, the conductive housing 120 can be made by methods such as stamping or welding metal sheets.

[0070] See Figure 2 and Figure 3 Each first terminal module 110 includes at least one first signal conductive element 111 and an insulating jacket 112. The first signal conductive element 111 includes a first mating end 1111, a first contact tail end 1112, and a first intermediate portion 1113 located between the first mating end 1111 and the first contact tail end 1112. The insulating jacket 112 covers the outside of at least a portion of the structure of the first signal conductive element 111.

[0071] It should be noted that the first mating end 1111 can be used to electrically connect with the gold fingers on electronic components such as daughtercards, so that the connector 10 of the lead assembly 100 using the embodiments of this application can be electrically connected with electronic components such as daughtercards. The first contact tail end 1112 can be used to electrically connect with the circuit board 20 when the connector 10 is connected to the circuit board 20. Exemplarily, the first contact tail end 1112 can be electrically connected to the circuit board 20 by means of soldering or bonding.

[0072] Among them, the gold fingers are usually a group of metal contacts on the edge of the card, and the gold fingers are usually arranged in strips.

[0073] In some examples, the insulating jacket 112 covers only the first mating end 1111 of the first signal conductive element 111, thereby protecting the contact area of ​​the first mating end 1111 and preventing interference from the external environment to the signal transmission of the first mating end 1111. In other examples, the insulating jacket 112 covers both the first mating end 1111 and the first intermediate portion 1113, thereby protecting the contact area of ​​the first mating end 1111 and the first intermediate portion 1113 of the first signal conductive element 111, and preventing interference from the external environment to the signal transmission of the first mating end 1111. In still other examples, the insulating jacket 112 covers the first mating end 1111, the first intermediate portion 1113, and the first contact tail end 1112, thereby protecting the contact area of ​​the first mating end 1111, the first intermediate portion 1113, and the first contact tail end 1112 of the first signal conductive element 111, and preventing interference from the external environment to the signal transmission of the first mating end 1111.

[0074] See Figure 1 , Figure 4as well as Figure 5 The conductive housing 120 integrally defines a plurality of mutually separated first chambers 121. The plurality of first terminal modules 110 correspond one-to-one with the plurality of first chambers 121. Each first terminal module 110 is arranged in the corresponding first chamber 121. With this arrangement, the conductive housing 120 can reduce electromagnetic interference between adjacent first terminal modules 110.

[0075] It should be noted that the conductive housing 120 integrally defines a plurality of mutually separated first chambers 121, that is, the conductive housing 120 is an integral workpiece, and the integrally formed conductive housing 120 defines a plurality of mutually separated first chambers 121.

[0076] According to the lead assembly 100 provided in the embodiments of this application, the conductive housing 120 defines a plurality of mutually separated first chambers 121, and each first terminal module 110 is arranged in a corresponding first chamber 121. This arrangement, through the combination of the conductive housing 120 and the plurality of first terminal modules 110, enables the first terminal modules 110 to effectively achieve efficient signal transmission and reliable electrical connection, effectively isolating each first terminal module 110, which helps reduce electromagnetic interference between adjacent first terminal modules 110 and reduces signal loss of the first terminal modules 110 in the connector 10, thereby ensuring efficient signal transmission of the first terminal modules 110. Secondly, the insulating jacket 112 covers the outer side of a portion of the structure of the first signal conductive element 111, thereby protecting the contact area of ​​the first signal conductive element 111 and helping to prevent interference from the external environment to the signal transmission of the first terminal module 110. Furthermore, the robust structure of the conductive housing 120 provides good structural protection for the first signal conductive element 111, which helps to increase the durability of the first terminal module 110 and reduce the occurrence of short circuits and leakage. Furthermore, the conductive housing 120 adopts an integrated design, which avoids structural loosening or instability problems that may occur when splicing multiple components. It provides more robust mechanical support for the entire lead assembly 100, effectively improving the impact and vibration resistance of the lead assembly 100, making it suitable for complex or harsh operating environments. The integrated conductive housing 120 can form a complete electromagnetic shielding structure, effectively reducing the impact of external electromagnetic interference on the first terminal module 110, while also preventing internal signal leakage, thereby further improving the stability and reliability of signal transmission.

[0077] In some embodiments, see Figure 1 , Figure 4 as well as Figure 5 The conductive outer shell 120 has a plurality of walls 122, and a first chamber 121 is defined between two adjacent walls 122. The plurality of walls 122 are spaced apart along the third direction Z.

[0078] According to the embodiments of this application, the wall 122 and the conductive housing 120 can be integrally formed. Multiple walls 122 act as partitions, and each first terminal module 110 is disposed between two adjacent walls 122, thereby ensuring physical and electrical isolation between the two first terminal modules 110. Furthermore, the walls 122 can provide good electromagnetic shielding, reducing electromagnetic interference between the two first terminal modules 110, thereby improving the signal transmission stability and reliability of the first terminal module 110.

[0079] In some embodiments, see Figure 4 and Figure 5 The conductive housing 120 defines an opening 123 communicating with the first chamber 121, and at least a portion of the first mating end 1111 extends through the opening 123 to the outside of the conductive housing 120. In some examples, a daughter card can be inserted into the opening 123 so that electronic components such as the daughter card and plug connector 10 can be electrically connected to the circuit board 20 via the connector 10 with lead assembly 100.

[0080] In some examples, opening 123 extends along the first direction X.

[0081] For example, the conductive housing 120 has an L-shaped cross-section and includes a first part and a second part. The first mating end 1111 is located in the first part, the first contact tail end 1112 is located in the second part, and the opening 123 is provided on the bottom surface of the first part, and the bottom surface of the first part is the mating surface. This arrangement allows the first mating end 1111 to be exposed from the opening 123 on the mating surface, so that the first mating end 1111 can make contact with the gold fingers on electronic components such as daughter cards.

[0082] According to the embodiments of this application, the opening 123 enables the conductive housing 120 to effectively isolate each first terminal module 110 to reduce electromagnetic interference between two adjacent first terminal modules 110, while preventing the conductive housing 120 from affecting the contact connection between the first mating terminal 1111 and electronic components such as the daughter card.

[0083] In some embodiments, see Figure 1 and Figure 4The conductive housing 120 has a first side 124 and a second side 125. The first chamber 121 is open on the first side 124 and the second side 125, that is, the first chamber 121 forms openings on the first side 124 and the second side 125 respectively, and the openings on the first side 124 and the second side 125 are connected. With this configuration, the first terminal module 110 can be inserted into the first chamber 121 through the openings on the first side 124 and the second side 125, thereby enabling the first terminal module 110 to be conveniently inserted into the first chamber 121 through the openings on the first side 124 and the second side 125. Furthermore, by providing openings on adjacent first side 124 and second side 125, this application adapts to the shape of the first signal conductive element 111, thereby enabling the first terminal module 110 to be conveniently inserted into the first chamber 121 through the openings on the first side 124 and the second side 125.

[0084] Figure 6 This diagram shows a schematic representation of the lead assembly 100 according to an embodiment of the present application. Figure 7 This diagram shows a schematic representation of the shielding member 130 according to an embodiment of this application. In some embodiments, see [link to relevant documentation]. Figure 6 and Figure 7 The embodiments of this application also include a shielding member 130, which covers the first side 124 and the second side 125 of the conductive housing 120, and the shielding member 130 can be electrically connected to the conductive housing 120 and the circuit board 20 respectively.

[0085] For example, one end of the shield 130 is electrically coupled to the conductive housing 120, and the other end of the shield 130 is electrically coupled to the circuit board 20. With this configuration, the conductive housing 120 can be electrically coupled to the shield 130, thereby grounding the conductive housing 120. This allows the conductive housing 120 and the wall 122 to form a signal shield between two adjacent first terminal modules 110, thereby effectively preventing the signal carried on one of the two adjacent first terminal modules 110 from causing crosstalk on the other first terminal module 110.

[0086] In this embodiment, grounding can shield signal interference by forming a low-impedance path through the shield 130 and the conductive housing 120, guiding the interference signal to the circuit board 20, thereby preventing the signal carried on one of the two adjacent first terminal modules 110 from generating crosstalk on the other first terminal module 110.

[0087] According to an embodiment of this application, each first terminal module 110 is arranged in the first chamber 121 of the corresponding conductive housing 120. The conductive housing 120 is grounded through electrical coupling with the shielding member 130. With this arrangement, the conductive housing 120 can provide shielding along the length direction of the first terminal module 110, thereby enabling the conductive housing 120 to provide shielding between two adjacent first terminal modules 110.

[0088] In some embodiments, the shielding element 130 is an integrated structure or an assembled structure.

[0089] In one example, the shielding component 130 can be an integral structure, meaning that the shielding component 130 can be manufactured using a one-piece molding process. This effectively simplifies the installation process of the shielding component 130, and the integrated design provides a continuous shielding layer, thereby reducing electromagnetic leakage of the first terminal module 110 and improving the signal shielding effect of two adjacent first terminal modules 110.

[0090] In another example, the shielding component 130 can adopt an assembly structure, that is, the shielding component 130 can be assembled from multiple individual structures. Preferably, the shielding component 130 is a detachable structure. A detachable shielding component 130 facilitates later maintenance or replacement of damaged parts, which helps to extend the service life of the connector 10 of the lead assembly 100 using the embodiments of this application. It should be noted that those skilled in the art can set the shielding component 130 as an integrated structure or an assembly structure according to actual needs.

[0091] In some embodiments, see Figure 6 and Figure 7 The shielding member 130 includes a first shielding part 131 and a second shielding part 132 that are electrically connected. The first shielding part 131 is disposed on the first side 124 and at least partially covers the opening of the first side 124, and the second shielding part 132 is disposed on the second side 125 and at least partially covers the opening of the second side 125.

[0092] For example, the first side 124 and the second side 125 are adjacent and arranged at an angle, for example, the angle between the first side 124 and the second side 125 is 90°. After the first terminal module 110 is inserted into the first chamber 121 through the openings of the first side 124 and the second side 125, the first shielding part 131 is attached to the first side 124 and covers the opening on the first side 124, and the second shielding part 132 is attached to the second side 125 and covers the opening on the second side 125. With this arrangement, the first terminal module 110 is shielded on each side by the conductive shell 120, the wall 122, the first shielding part 131, and the second shielding part 132, which can prevent external interference from entering the first chamber 121 through the openings of the first side 124 and the second side 125, and can prevent the external environment from interfering with the signal transmission of the first terminal module 110.

[0093] Figure 8 This diagram shows a schematic representation of the lead assembly 100 according to an embodiment of the present application. Figure 9 Show Figure 8 An enlarged diagram of A in the diagram. Figure 10 Show Figure 8 An enlarged diagram of B in the diagram is shown in some examples. Figures 8 to 10 The conductive housing 120 includes a first part and a second part. A first side 124 is located in the first part, and a second side 125 is located in the second part. The first part has a top surface (first side 124), a bottom surface, and a connecting surface connecting the top surface and the bottom surface. An opening 123 is provided on the bottom surface of the first part. A first shielding part 131 is provided on the top surface (first side 124) of the first part, and a second shielding part 132 is provided on the second side 125. The first shielding part 131 has a first extension part 1311. The first extension part 1311 extends to the connecting surface and the bottom surface of the first part, respectively. The first extension part 1311 is in contact with the connecting surface or the bottom surface, and the portions of the first extension part 1311 and the first mating end 1111 extending to the outside of the opening 123 are flush, so that the first extension part 1311 can form a grounding part that is in contact with the gold fingers on electronic components such as daughter cards.

[0094] In some embodiments, see Figures 8 to 10 The first extension 1311 is located between two adjacent first terminal modules 110. This arrangement enables the first extension 1311 to form a signal shield between the adjacent first terminal modules 110, so as to effectively prevent the signal carried on one of the two adjacent first terminal modules 110 from causing crosstalk on the other first terminal module 110.

[0095] In some embodiments, see Figure 7The first shielding part 131 and / or the second shielding part 132 are sheet-like structures. The sheet-like first shielding part 131 and the second shielding part 132 are lightweight, and the first shielding part 131 and the second shielding part 132 can provide a continuous shielding layer, which can effectively shield electromagnetic interference between two adjacent first terminal modules 110, thereby reducing signal crosstalk.

[0096] In some embodiments, the first shielding portion 131 and the second shielding portion 132 are connected by assembly. Exemplarily, at least one positioning protrusion is provided on the first side surface 124, and at least one positioning groove is provided on the first shielding portion 131. The positioning protrusion is engaged within the positioning groove, thereby achieving positioning between the first shielding portion 131 and the first side surface 124. The second shielding portion 132 defines a third extension 1322 on the side adjacent to the first shielding portion 131. The third extension 1322 extends into the first chamber 121, and the bottom surface of the first shielding portion 131 contacts the third extension 1322 of the second shielding portion 132, thereby achieving electrical connection between the first shielding portion 131 and the second shielding portion 132.

[0097] For example, the number of third extensions 1322 corresponds to the number of first chambers 121, and the third extensions 1322 extend into the corresponding first chambers 121.

[0098] In some embodiments, the first shielding part 131 and the second shielding part 132 are typically made of metal materials. Metal materials can effectively reflect and absorb electromagnetic waves, reducing signal interference and crosstalk of the external environment to the first terminal module 110.

[0099] For example, the first shielding portion 131 and the second shielding portion 132 are made of metal materials such as aluminum and copper, thereby providing excellent conductivity and helping to prevent external environment from interfering with the signal transmission of the first terminal module 110. Secondly, the metal material has high mechanical strength and corrosion resistance, which allows the conductive shell 120 to be used in the connector 10 to improve the service life of the connector 10.

[0100] In some embodiments, see Figure 7 and Figure 10 The second shielding portion 132 includes at least one second extension portion 1321, which is located between two adjacent first terminal modules 110 and is used for electrical connection with the circuit board 20.

[0101] For example, the circuit board 20 is generally disposed at the end of the second part away from the first part. The first contact tail 1112 of each first signal conductive element 111 is in contact with the circuit board 20. The second extension 1321 is located at the end of the second shielding part 132 away from the first shielding part 131 and between the first contact tails 1112 of the first signal conductive elements 111 of two adjacent first terminal modules 110. The second extension 1321 is in contact with the circuit board 20 so that the shielding member 130 can achieve the grounding function. The second extension 1321 can form a signal shield between adjacent first terminal modules 110, thereby effectively preventing the signal carried on one of the two adjacent first terminal modules 110 from generating crosstalk on the other first terminal module 110.

[0102] In some examples, the second extension 1321 of the second shield 132 and the first contact tail 1112 of the first signal conductive element 111 can be electrically connected to the printed circuit board by means of soldering or bonding.

[0103] In some embodiments, see Figure 6 The first shielding part 131 is welded and fixed to the first side surface 124. And / or, the second shielding part 132 is welded and fixed to the second side surface 125. The welding method provides a strong fixation between the first shielding part 131 and the second shielding part 132 and the conductive shell 120, thereby ensuring a tight bond between the first shielding part 131 and the second shielding part 132 and the conductive shell 120. Furthermore, the welding method eliminates gaps between the first shielding part 131 and the second shielding part 132 and the conductive shell 120, and the weld seam between the first shielding part 131 and the second shielding part 132 and the conductive shell 120 has good conductivity, ensuring the continuity of electromagnetic shielding.

[0104] In some embodiments, see Figure 3 The first intermediate portion 1113 is in a torsional state. This configuration provides the first intermediate portion 1113 with a certain degree of elasticity, allowing it to make minor adjustments through elastic deformation when the connector 10 is subjected to mechanical stress or vibration, thereby preventing damage to the first signal conductive element 111. Furthermore, the torsional state of the first intermediate portion 1113 ensures that the first mating terminal 1111 maintains its position and shape, thus preserving the characteristic impedance of the first mating terminal 1111.

[0105] In some embodiments, the torsion angle of the first intermediate portion 1113 is greater than or equal to 70° and less than or equal to 110°.

[0106] For example, the torsion angle of the first intermediate portion 1113 is 70°, 80°, 90°, 100°, or 110°. It should be noted that this is merely an example and does not constitute a limitation on this application. Those skilled in the art will understand that the torsion angle of the first intermediate portion 1113 can also be selected according to requirements.

[0107] In some embodiments, see Figure 3 The first intermediate portion 1113 includes a torsion structure disposed adjacent to the first mating end 1111. In some examples, the first intermediate portion 1113 includes a first segment 1113a and a second segment 1113b connected together, the first segment 1113a and the second segment 1113b being disposed at an included angle, the first segment 1113a being connected to the first mating end 1111, and the second segment 1113b being connected to the first contact tail end 1112. The first segment 1113a is in a torsion state.

[0108] For example, the first segment 1113a corresponds to the position of the first shielding part 131, and the second segment 1113b corresponds to the position of the second shielding part 132.

[0109] In some embodiments, the conductive housing 120 is die-cast from a copper alloy. Copper alloy has excellent conductivity and corrosion resistance, making it suitable for applications requiring high shielding performance. Furthermore, by selecting a copper alloy as the material for the conductive housing 120 and using a die-casting process, the conductive housing 120 can achieve good shielding performance.

[0110] In some embodiments, the shape of the insulating jacket 112 is adapted to the first chamber 121, thereby ensuring that the insulating jacket 112 and the first chamber 121 can fit tightly when the insulating jacket 112 is snapped into the first chamber 121, and ensuring that the conductive housing 120 and the first terminal module 110 of the connector 10 will not shift relative to each other under vibration.

[0111] In some embodiments, see Figure 1 , Figure 4 , Figure 5 as well as Figure 6 The first chamber 121 includes a first groove 1211 extending along a first direction X and a second groove 1212 extending along a second direction Y. A portion of the structure of the first mating end 1111 extends out of the first groove 1211, and at least a portion of the first contact tail end 1112 is arranged in the second groove 1212. The first direction X and the second direction Y intersect.

[0112] According to an embodiment of this application, the first groove 1211 corresponds to the opening on the first side 124, and the second groove 1212 corresponds to the opening on the second side 125. When the first terminal module 110 is inserted into the first chamber 121 from the openings of the first side 124 and the second side 125, the arrangement of the first groove 1211 and the second groove 1212 can adapt to the shape of the first mating end 1111, the first contact tail end 1112 and the first middle part 1113 in the first terminal module 110, thereby ensuring that the first module can be correctly positioned when inserted into the first chamber 121 and reducing installation errors.

[0113] In some embodiments, see Figure 4 and Figure 5 Multiple first chambers 121 are arranged at intervals along the third direction Z on the conductive shell 120, and the first direction X, the second direction Y and the third direction Z intersect each other in pairs.

[0114] For example, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other, that is, the preset angle between the third direction Z, the second direction Y and the first direction X can be 90°. Of course, the angle between the third direction Z, the second direction Y and the first direction X can also be other values, such as 50°, 70°, 80°, 95°, 112°, 120°, etc. The specific value of the preset angle between the third direction Z, the second direction Y and the first direction X is not specifically limited in this embodiment of the utility model.

[0115] For example, multiple walls 122 are spaced apart along the third direction Z to separate multiple conductive housings 120 arranged along the third direction Z. This arrangement can, on the one hand, divide the conductive housing 120 into multiple independent first chambers 121, forming good electromagnetic isolation between the first chambers 121 to avoid signal interference between different first terminal modules 110. On the other hand, it can make the arrangement of the multiple first chambers 121 perpendicular to the length direction of the first terminal modules 110, ensuring that the conductive housing 120 can accommodate more first terminal modules 110 within a limited size, thereby improving the layout rationality of the conductive housing 120.

[0116] Figure 11 This diagram shows a structural schematic of the connection body 200 according to an embodiment of this application. Figure 12 This diagram shows a structural schematic of the connector 10 according to an embodiment of this application. Figure 13 This diagram shows a structural schematic of the second terminal module 300 according to an embodiment of this application. Figure 14 This diagram illustrates the structure of a third terminal module 400 according to an embodiment of this application. See also, as another aspect of this application... Figures 11 to 14The application embodiment also provides a connector 10, which includes a conductive shell 120, a connecting body 200, a first row of terminal groups, and a second row of terminal groups.

[0117] See Figure 1 , Figure 4 , Figure 5 , Figure 11 as well as Figure 12 The conductive housing 120 integrally defines a plurality of mutually spaced first chambers 121. The connecting body 200 defines a slot 210, at least one second chamber 220 and at least one third chamber 230, the at least one second chamber 220 being mutually spaced, the at least one third chamber 230 being mutually spaced, and the conductive housing 120 being snapped into the slot 210, thereby realizing the connection between the conductive housing 120 and the connecting body 200.

[0118] See Figure 11 and Figure 12 The first row of terminal groups includes multiple first terminal modules 110 and at least one second terminal module 300. The multiple first terminal modules 110 and multiple first chambers 121 correspond one-to-one. Each first terminal module 110 is arranged in the corresponding first chamber 121, and the second terminal module 300 is arranged in the second chamber 220.

[0119] The conductive housing 120 defines a plurality of mutually separated first chambers 121 and second chambers 220. Each first terminal module 110 is arranged in a corresponding first chamber 121, and each second terminal module 300 is arranged in a corresponding second chamber 220. This arrangement enables the first terminal module 110 and the second terminal module 300 to achieve efficient signal transmission and reliable electrical connection, effectively isolating each first terminal module 110 and the second terminal module 300. This helps reduce electromagnetic interference between adjacent first terminal modules 110 and second terminal modules 300, reduces signal loss between first terminal modules 110 and second terminal modules 300, and ensures efficient signal transmission between first terminal modules 110 and second terminal modules 300.

[0120] See Figure 2 , Figure 3 as well as Figure 13 The first terminal module 110 includes a plurality of first signal conductive elements 111 constituting a differential pair, and the second terminal module 300 includes a plurality of second signal conductive elements 310 constituting a differential pair.

[0121] In the embodiments of this application, the type of signal transmitted by connector 10 is not specifically limited. For example, the first terminal module 110 includes a plurality of first signal conductive elements 111 constituting a differential pair, and the second terminal module 300 includes a plurality of second signal conductive elements 310 constituting a differential pair. It should be noted that the signal transmitted by connector 10 is not limited to differential pair signals.

[0122] See Figure 12 and Figure 14 The second row of terminal groups includes at least one third terminal module 400. The third terminal module 400 includes a plurality of third signal conductive elements 410 constituting a differential pair. The third terminal module 400 is arranged in a corresponding third chamber 230.

[0123] According to the embodiments of this application, the separate arrangement of multiple first chambers 121, second chambers 220, and third chambers 230 allows for the independent arrangement of different terminal modules in the first and second row terminal groups, facilitating adjustments to the type and quantity of terminal modules according to actual needs, thereby enhancing the design flexibility of the connector 10. Secondly, the first terminal module 110, second terminal module 300, and third terminal module 400 all include signal conductive elements constituting differential pairs, enabling each terminal module to support multiple signal types (such as single-ended signals, differential signals, etc.) to adapt to different application scenarios. Furthermore, by arranging multiple first terminal modules 110 within multiple first chambers 121, and by arranging the second terminal modules 300 and third terminal modules 400 in the second chambers 220 and third chambers 230 respectively, high-density signal transmission can be achieved while maintaining signal integrity. Moreover, by dividing the terminal modules into two rows, namely the first row terminal group and the second row terminal group, the embodiments of this application can achieve high-density signal transmission within a limited space while maintaining good electromagnetic compatibility.

[0124] In some embodiments, see Figure 5 , Figure 6 as well as Figure 12 The slot 210 defines a slot 211 on at least one side in the third direction Z, and the conductive housing 120 is provided with a locking protrusion 500 on at least one side in the third direction Z, the locking protrusion 500 being locked in the slot 211.

[0125] For example, the slot 210 has slots 211 defined on both sides in the third direction Z, and the conductive housing 120 has locking protrusions 500 on both sides in the third direction Z. The locking protrusions 500 are engaged with the corresponding slots 211, thereby achieving the connection between the conductive housing 120 and the connecting body 200. In other examples, the slot 210 has a slot 211 defined on one side in the third direction Z, and the conductive housing 120 has a locking protrusion 500 on one side in the third direction Z. The locking protrusion 500 is engaged with the corresponding slot 211, thereby achieving the connection between the conductive housing 120 and the connecting body 200.

[0126] According to the embodiments of this application, the mechanical cooperation between the slot 211 and the locking protrusion 500 can ensure a stable connection between the conductive shell 120 and the connecting body 200, and prevent the conductive element and the connecting body 200 from loosening when the connector 10 is subjected to vibration or external force.

[0127] In some embodiments, see Figures 1 to 3 , Figure 11 , Figure 12 Each first terminal module 110 includes at least one first signal conductive element 111 and an insulating jacket 112. The insulating jacket 112 covers the outer side of a portion of the structure of the first signal conductive element 111. The first signal conductive element 111 includes a first mating end 1111, a first intermediate portion 1113, and a first contact tail end 1112. The second terminal module 300 includes a second mating end 311, a second intermediate portion 312, and a second contact tail end 313. The third terminal module 400 includes a third mating end 411, a third intermediate portion 412, and a third contact tail end 413. The first contact tail end 1112 and the second contact tail end 313 are arranged in the same direction, and the first contact tail end 1112 and the third contact tail end 413 are arranged in opposite directions.

[0128] It should be noted that the first signal conductive element 111, the second signal conductive element 310 and the third signal conductive element 410 all have a mating end, a middle part and a first contact tail. The first signal conductive element 111, the second signal conductive element 310 and the third signal conductive element 410 may have different size ratios due to different models.

[0129] According to the embodiments of this application, on the one hand, the phase separation between the first chamber 121, the second chamber 220 and the third chamber 230 can shield the electromagnetic interference between the first signal conductive element 111, the second signal conductive element 310 and the third signal conductive element 410. On the other hand, the orientation of the mating ends, the middle part and the contact tail of the first signal conductive element 111 and the second signal conductive element 310 in the first row of terminal groups can be set to be the same, and the first contact tail 1112 and the third contact tail 413 can be set to be opposite to each other, so as to ensure that the conductive housing 120 can accommodate more terminal modules within a limited size, thereby improving the layout rationality of the connector 10.

[0130] Figure 15 The diagram shows a structural schematic of an electronic system 1 according to an embodiment of this application. See also, as another aspect of this application, [link to relevant documentation]. Figure 1 , Figure 6 , Figure 15 This application embodiment also provides an electronic system 1, which includes a circuit board 20 and a connector 10. The connector 10 includes a lead assembly 100, which includes a conductive housing 120, a shield 130, and a plurality of first terminal modules 110. The shield 130 covers a first side 124 and a second side 125 of the conductive housing 120. The conductive housing 120 integrally defines a plurality of mutually separated first chambers 121. The first terminal modules 110 are arranged in the corresponding first chambers 121. The shield 130 is electrically connected to the conductive housing 120 and the circuit board 20 respectively.

[0131] In some embodiments of this application, the connector 10 is the connector 10 provided in any of the above embodiments of this application.

[0132] The conductive housing 120 defines a plurality of mutually separated first chambers 121, and each first terminal module 110 is arranged in a corresponding first chamber 121. This arrangement enables the first terminal modules 110 to effectively achieve efficient signal transmission and reliable electrical connection, thereby effectively isolating each first terminal module 110, which helps to reduce electromagnetic interference between adjacent first terminal modules 110, reduce signal loss of the first terminal modules 110, and ensure efficient signal transmission of the first terminal modules 110.

[0133] For example, one end of the shield 130 is electrically coupled to the conductive housing 120, and the other end of the shield 130 is electrically coupled to the circuit board 20. With this configuration, the conductive housing 120 can be electrically coupled to the shield 130, thereby grounding the conductive housing 120. This allows the conductive housing 120 and the wall 122 to form a signal shield between two adjacent first terminal modules 110, thereby effectively preventing the signal carried on one of the two adjacent first terminal modules 110 from causing crosstalk on the other first terminal module 110.

[0134] According to an embodiment of this application, on one hand, the first terminal module 110 is covered by a conductive shell 120 and a shield 130 on each side, preventing external interference from entering the first chamber 121 through the openings of the first side 124 and the second side 125, which helps to prevent the external environment from interfering with the signal transmission of the first terminal module 110. On the other hand, one end of the shield 130 is electrically coupled to the conductive shell 120, and the other end of the shield 130 is electrically coupled to the circuit board 20. With this configuration, the conductive shell 120 can be electrically coupled to the shield 130, thereby grounding the conductive shell 120. This allows the conductive shell 120 and the wall 122 to form a signal shield between two adjacent first terminal modules 110, thereby effectively preventing the signal carried on one of the two adjacent first terminal modules 110 from causing crosstalk on the other first terminal module 110.

[0135] In some embodiments, see Figure 1 , Figure 11 , Figure 12 as well as Figure 15 The connector 10 also includes a connection body 200, which defines a slot 210. The conductive housing 120 is inserted into the slot 210 to achieve a connection between the conductive housing 120 and the connection body 200.

[0136] For example, the shape of the slot 210 is adapted to the shape of the conductive housing 120. The conductive housing 120 has two parallel sides in the third direction Z, and the slot 210 has two parallel sidewalls in the third direction Z. The two sides of the conductive housing 120 in the third direction Z respectively abut against the sidewalls of the slot 210 in the third direction Z. With this configuration, the connection between the conductive housing 120 and the connecting body 200 can be realized.

[0137] In some embodiments, see Figure 11 , Figure 12 as well as Figure 15The application also includes at least one second terminal module 300 and at least one third terminal module 400. The second terminal module 300 includes a plurality of second signal conductive elements 310 constituting a differential pair, and the third terminal module 400 includes a plurality of third signal conductive elements 410 constituting a differential pair. The connection body 200 further defines at least one second chamber 220 and at least one third chamber 230. The second terminal module 300 is disposed in the second chamber 220, and the third terminal module 400 is disposed in the corresponding third chamber 230.

[0138] It is understood that the first terminal module 110, the second terminal module 300, and the third terminal module 400 can be selected with different types of terminals or with the same type of terminals, and those skilled in the art can adjust this according to their needs.

[0139] In some embodiments, the conductive housing 120 and the connecting body 200 are disposed on the same side of the circuit board 20, and the first terminal module 110, the second terminal module 300 and the third terminal module 400 are electrically connected to the circuit board 20 respectively.

[0140] In some embodiments, see Figure 2 , Figure 3 , Figure 11 as well as Figure 13 The first terminal module 110 includes at least one first signal conductive element 111. The first signal conductive element 111 includes a first mating end 1111, a first intermediate portion 1113, and a first contact tail end 1112. The second signal conductive element 310 includes a second mating end 311, a second intermediate portion 312, and a second contact tail end 313. The second contact tail end 313 is electrically connected to the circuit board 20. The second intermediate portion 312 extends away from the circuit board 20. The first contact tail end 1112 and the second contact tail end 313 are arranged in the same direction.

[0141] In some embodiments, see Figure 11 and Figure 14 The third signal conductive element 410 includes a third mating end 411, a third intermediate portion 412 and a third contact tail end 413. The third contact tail end 413 is electrically connected to the circuit board 20. The third intermediate portion 412 extends away from the circuit board 20. The first contact tail end 1112 and the third contact tail end 413 are arranged opposite to each other.
