Description

[Technical field]

[0001] Books The application relates to the field of electronic technology, and in particular to a connector assembly and a manufacturing method thereof, and an electronic device. [Background technology]

[0002] In a communication device system, the combined backplane and sub-boards are usually printed circuit boards ( P The crosstalk indicators of connector assemblies are connected through PCB (Cable-Board) wiring. However, as the speed of communication devices evolves to 56Gbps and 112Gbps, the loss caused by traditional PCB wiring also faces greater challenges and can hardly meet the system's requirements for passive links. Compared with PCB wiring, connector assemblies have significant improvement in terms of loss. Replacing PCB wiring with connector assemblies becomes one of the main technological directions to reduce loss. However, currently, the crosstalk indicators of connector assemblies in the industry cannot meet the application requirement of 112Gbps. Summary of the Invention

[0003] Embodiments of the present application provide a connector assembly that reduces the effects of crosstalk in the connector assembly, a method for manufacturing the connector assembly, and an electronic device that includes the connector assembly, and provide a connector assembly and an electronic device that meet the application requirements of 112 Gbps.

[0004] According to a first aspect, a connector assembly is provided. The connector assembly includes a metal housing, a conductive component, a wire, and a shielding layer. The metal housing includes a shielding cavity. The conductive component is housed within the shielding cavity. The wire is partially located within the shielding cavity and electrically connected to one end of the conductive component. The shielding layer is wrapped around the wire. At least two electrical connections are disposed on an outer surface of the shielding layer. The at least two electrical connections face in different directions and are each electrically connected to a portion of the metal housing facing the at least two electrical connections so as to reduce crosstalk effects in the connector assembly.

[0005] In the present application, the conductive component is accommodated in the shield cavity, the wire is partially disposed in the shield cavity and electrically connected to one end of the conductive component, and at least two electrical connections on the shield layer wrapped around the wire face different directions and are electrically connected to the portion of the metal housing that the at least two electrical connections face. That is, the at least two electrical connections on the shield layer that face different directions are electrically connected to the peripheral wall of the shield cavity that the at least two electrical connections face. Thus, when the signal returns from the peripheral wall of the shield cavity to the wire, the signal on the peripheral wall of the shield cavity is transmitted to the electrical connection on the shield layer that is close to the peripheral wall. Compared to when the peripheral wall of the shield cavity is electrically connected to only one electrical connection on the shield layer, the signal return path is shorter and the loop inductance is smaller, thereby effectively reducing the crosstalk effect of the connector assembly and supporting signal transmission at 112Gbps and higher rates.

[0006] In some embodiments, the shield layer includes a first surface, a second surface, a third surface, and a fourth surface that face different directions and are connected in sequence, and at least two electricityThe connection portion includes a first electrical connection portion and a second electrical connection portion, the first electrical connection portion extending from the first surface to the third surface and the second electrical connection portion located on the fourth surface.

[0007] It will be understood that the first electrical connection and the second electrical connection are distributed together on the entire peripheral surface of the shield layer, so that the entire peripheral surface of the shield layer can be electrically connected to the peripheral wall of the shield cavity. That is, the four surfaces of the shield layer are electrically connected to the four peripheral walls of the shield cavity corresponding to the four surfaces, respectively. Thus, when the signal returns from the four peripheral walls of the shield cavity to the wire, the signal on the four peripheral walls of the shield cavity is transmitted to the four surfaces of the shield layer close to the four peripheral walls, respectively. Compared with the case where only one of the four peripheral walls of the shield cavity is electrically connected to the surface of the shield layer, the signal return path is shorter and the loop inductance is smaller, thereby effectively reducing the crosstalk effect of the connector assembly and supporting signal transmission at rates of 112 Gbps and higher.

[0008] In some embodiments, the metal housing includes a first housing and a second housing, the second housing is buckled to the first housing to form a shielded cavity, and the at least two electrical connections are electrically connected to the first housing and the second housing facing the at least two electrical connections, respectively. The first housing and the second housing form one or more shielded cavities. The shielded cavities are formed by the first housing and the second housing, thereby facilitating assembly of the connector assembly.

[0009] In some embodiments, there are at least two shield cavities, the at least two shield cavities forming at least two rows of shield cavities, the at least two rows of shield cavities including a first row of shield cavities and a second row of shield cavities, the metal housing includes a first housing, a second housing, and a metal sheet, the metal sheet is located between the first housing and the second housing, the metal sheet and the first housing forming the first row of shield cavities, the metal sheet and the second housing forming the second row of shield cavities, each conductive component and each wire corresponds to one shield cavity, the at least two electrical connections located in the first row of shield cavities are electrically connected to the first housing and the metal sheet facing each other, and the at least two electrical connections located in the second row of shield cavities are electrically connected to the second housing and the metal sheet facing each other.

[0010] In this embodiment, the amount of conductive parts and the amount of wires are the same as the amount of shielding cavities, and each conductive part and a portion of the wire connected to the conductive part are arranged in a separate shielding cavity, so as to separately shield each conductive part and the wire connected to the conductive part. This effectively reduces the effect of crosstalk between different conductive parts and the wires connected to the conductive parts, thereby effectively reducing the effect of crosstalk in the connector assembly and supporting signal transmission at rates of 112 Gbps and higher.

[0011] In some embodiments, the metal sheet includes a first metal sheet and a second metal sheet, the first metal sheet is connected to a first housing, the second metal sheet is disposed on a side of the first metal sheet that backs the first housing and is connected to a second housing, a first row of shielding cavities is formed between the first metal sheet and the first housing, a second row of shielding cavities is formed between the second metal sheet and the second housing, at least two electrical connections located in the first row of shielding cavities are electrically connected to the first housing and the first metal sheet that the at least two electrical connections face, respectively, and at least two electrical connections located in the second row of shielding cavities are electrically connected to the second housing and the second metal sheet that the at least two electrical connections face, respectively.

[0012] In this embodiment, there are two metal sheets, and the two metal sheets form the first row shielding cavity and the second row shielding cavity with the first housing and the second housing, respectively, so that the two metal sheets (the first metal sheet and the second metal sheet) can be staggered, thereby facilitating the staggered arrangement of the two metal sheets (the first metal sheet and the second metal sheet) and further facilitating the staggered arrangement of the conductive components of the two rows. In this embodiment, the first housing, the second housing, the first metal sheet, and the second metal sheet are fixed through connection, thereby facilitating the assembly of the connector assembly.

[0013] In some embodiments, the first housing includes a groove and a plurality of partition walls, the plurality of partition walls are spaced apart in the groove to form a plurality of first shield grooves, and the first metal sheet covers the openings of the first shield grooves to form a first row of shield cavities. That is, the cavity walls of the first row of shield cavities are formed by connecting the first metal sheet, the partition walls, and the groove walls of the grooves. The first body and the plurality of partition walls are integrated, thereby ensuring a connection structure between the first body and the partition walls.

[0014] In some embodiments, the portion of the wire located within the shield cavity is embedded in the first shield groove such that the electrical connection on the shield layer facing the groove wall of the first shield groove is attached to the groove wall. All electrical connections on the shield layer facing the groove wall of the first shield groove are electrically connected to the groove wall of the first shield groove. Thus, when the signal returns from the groove wall of the first shield groove to the electrical connection on the shield layer of the wire facing the first shield groove, the signal on the groove wall of the first shield groove is transmitted to the electrical connection on the shield layer close to the groove wall. The signal return path is shorter and the loop inductance is smaller, thereby effectively reducing the crosstalk effect of the connector assembly and supporting signal transmission at rates of 112 Gbps and higher.

[0015] In some embodiments, the shape of the electrical connection on the shielding layer facing the groove wall is the same as the shape of the groove wall, so that the electrical connection on the shielding layer facing the groove wall of the first shielding groove is closely attached to the groove wall of the first shielding groove. In this way, good electrical connection is implemented between the electrical connection on the three surfaces of the shielding layer and the groove wall of the first shielding groove, thereby effectively reducing the crosstalk of the connector assembly.

[0016] In some embodiments, a conductive part is disposed on a surface of the first metal sheet facing the first shielding groove, and the conductive part abuts an electrical connection part on the shielding layer lining the first shielding groove. In this embodiment, the conductive part is an elastomer. Since the elastomer is elastic, the first metal sheet can be electrically connected to a wire, and the wire can abut the groove wall of the first shielding groove, thereby ensuring a good electrical connection between the shielding layer of the wire and the groove wall of the first shielding groove, and effectively reducing the crosstalk of the connector assembly. Of course, the conductive part may be a convex structure, such as a convex hull structure.

[0017] In some embodiments, the connector assembly further includes a limiting block, the limiting block is disposed in the first shielding groove, and the end of the contact portion is embedded in the surface of the limiting block to restrict the contact portion. Specifically, the limiting block is made of an insulating material, and the end of the conductive part that is away from the wire may be partially embedded in the surface of the limiting block that lines the first shielding groove, or may be disposed on the surface of the limiting block that lines the first shielding groove. The limiting block restricts the conductive part to avoid deformation of the conductive part during use. In addition, the limiting block can further prevent the conductive part from being electrically connected to the groove wall of the first shielding groove, thereby improving the service life of the connector assembly and improving the safety performance of the connector assembly.

[0018] In some embodiments, the second housing includes a plurality of partition plates spaced apart on a surface of the second housing facing the first housing and forming a plurality of second shielding grooves together with the surface of the second housing facing the first housing, and a second metal sheet covering openings of the second shielding grooves to form a second row of shielding cavities.

[0019] In some embodiments, the conductive component includes a contact portion and a connection portion that are connected to each other, the connection portion is electrically connected to a wire, and the contact portion is exposed from a surface of a second housing that lines the first housing, and the contact portion is exposed from a surface of the second housing for connection to another associated device.

[0020] In some embodiments, the connector assembly further includes an insulator, the insulator being wrapped around the connection portion near the contact portion. The insulator is wrapped around the conductive component to secure the two conductive terminals of the conductive component. Additionally, the insulator can further isolate the conductive component from the first shield groove or isolate the conductive component from the cavity wall of the second row of shield cavities to prevent electrical connection between the conductive component and the groove wall of the first shield groove or the cavity wall of the second row of shield cavities.

[0021] In some embodiments, the connector assembly further includes a fastener, which is wound around the joint between the connection portion and the wire to fix the wire disposed in the shield cavity of the same row. The fastener can protect the solder joint between the conductive component and the wire. In addition, the fastener can be used to fix multiple conductive components and multiple wires located in the same row to form a transmission plate, so as to quickly assemble the connector assembly. This effectively improves the manufacturing efficiency of the connector assembly and reduces the manufacturing cost of the connector assembly.

[0022] According to a second aspect, an electronic device is provided. The electronic device includes a circuit board and the connector assembly described above. The connector assembly is connected between the circuit board and another device, or the connector assembly is connected between two elements of the circuit board. In the electronic device having the connector assembly provided in the present application, the loss and crosstalk of the connector assembly are effectively reduced, and 112G bps and higher signaling rates are supported.

[0023] According to a third aspect, there is provided a method of manufacturing a connector assembly, the method comprising: electrically connecting the conductive component to the wire to form a transmission component, wherein a shielding layer is wrapped around the wire and at least two electrical connections are disposed on an outer surface of the shielding layer, the at least two electrical connections facing in different directions; The method includes providing a metal housing and mounting a transmission component within a shielded cavity of the metal housing, wherein the at least two electrical connections are respectively electrically connected to portions of the metal housing facing the at least two electrical connections.

[0024] In the present application, a transmission component is formed first, and then the transmission component is mounted in a shielding cavity of a metal housing, and at least two electrical connections are electrically connected to the part of the metal housing that the at least two electrical connections face. That is, at least two electrical connections on the shielding layer facing different directions are electrically connected to the peripheral wall of the shielding cavity that the at least two electrical connections face. Therefore, when the signal returns to the wire from the peripheral wall of the shielding cavity, the signal on the peripheral wall of the shielding cavity is transmitted to the electrical connection on the shielding layer close to the peripheral wall. Compared with the case where the peripheral wall of the shielding cavity is electrically connected to only one electrical connection on the shielding layer, the signal return path is shorter and the loop inductance is smaller, thereby effectively reducing the crosstalk effect of the connector assembly and supporting signal transmission at 112Gbps and higher rates.

[0025] In some embodiments, providing a metal housing includes forming a first housing and a second housing, and mounting the transmission component in the shielding cavity of the metal housing includes placing the transmission component on the first housing and buckling the second housing to the first housing such that the transmission component is mounted in the shielding cavity formed by the first housing and the second housing. The first housing and the second housing form one or more shielding cavities, and the at least two electrical connections are electrically connected to the first housing and the second housing, respectively, facing the at least two electrical connections. The shielding cavities are formed by the first housing and the second housing, thereby facilitating assembly of the connector assembly.

[0026] In some embodiments, the manufacturing method further includes arranging a plurality of transmission components in a row to form a first transmission plate and a second transmission plate, and providing a metal housing includes forming the first housing and the second housing, providing a metal sheet including a first metal sheet and a second metal sheet, mounting the first metal sheet on the first transmission plate, and mounting the second metal sheet on the second transmission plate, and mounting the transmission components within the shielding cavity of the metal housing includes placing the first transmission plate, to which the first metal sheet is attached, on a side of the first metal sheet that faces the first housing and then mounting the second transmission plate, to which the second metal sheet is attached, on a side of the first metal sheet that backs the first housing. and finally, mounting the second housing on the first housing such that the transmission components of the first transmission plate are positioned within the shielding cavity formed by the first housing and the first metal sheet, the transmission components of the second transmission plate being positioned within the shielding cavity formed by the second housing and the second metal sheet, at least two electrical connection portions located within the shielding cavities of the first row being electrically connected to the first housing and the first metal sheet which the at least two electrical connection portions face, respectively, and at least two electrical connection portions located within the shielding cavities of the second row being electrically connected to the second housing and the second metal sheet which the at least two electrical connection portions face, respectively.

[0027] In this embodiment, first, a first metal sheet is attached onto a first transmission plate, a second metal sheet is attached onto a second transmission plate, and then the first metal sheet and No. 1 the transmission plate is mounted on the first housing, and the second metal sheet and the second transmission plate are mounted on the first housing. That is to say, in this embodiment, different elements of the connector assembly are modularized and then assembled, thereby effectively improving the assembly efficiency of the connector assembly, improving the manufacturing efficiency of the connector assembly, and reducing the manufacturing cost.

[0047] The following describes embodiments of the present application with reference to the accompanying drawings in which:

[0048] FIG. 1 is a schematic diagram of the structure of an electronic device 1000 according to an embodiment of the present application.

[0049] An embodiment of the present application provides an electronic device 1000. The electronic device 1000 includes, but is not limited to, an electronic device 1000 having a connector assembly, such as a large communication device, a super-performance server, a supercomputer, an industrial computer, or a high-end storage device. In this application, an example in which the electronic device 1000 is a communication device is used for concrete description.

[0050] The electronic device 1000 includes a connector assembly 100 and a circuit board. The circuit board includes a first circuit board 200 and a second circuit board 300. In this embodiment, the connector assembly 100 is connected between the first circuit board 200 and the second circuit board 300. The first circuit board 200 may be a primary circuit board. The primary circuit board, also called a host board, system board, logic board, motherboard, etc., is a primary circuit board that constitutes a complex electronic system, such as a communication device. The second circuit board 300 may be a secondary circuit board, which is a circuit board other than the primary circuit board in the electronic device 1000. The function of the connector assembly 100 is to build a bridge for communication between the first circuit board 200 and the second circuit board 300 so that an electric current can flow to implement a predetermined function of the circuit. In the electronic device 1000 having the connector assembly 100 provided in the present application, the loss and crosstalk of the connector assembly 100 are effectively reduced, and the 112G bps and higher rate signal transmission is supported.

[0051] Of course, in other embodiment scenarios, both the first circuit board and the second circuit board may alternatively be secondary circuit boards, and the connector assembly may be connected between the two secondary circuit boards. In other embodiment scenarios, the connector assembly may alternatively be connected between two elements of a first circuit board, or the connector assembly may be connected between two elements of a second circuit board.

[0052] In this embodiment, the first circuit board 200 is integrated with plug-in terminals and various chips 201, such as a central processing chip and a system chip. The second circuit board 300 is also integrated with chips 301 and plug-in terminals 302, and the connector assembly 100 is connected between the plug-in terminals of the first circuit board 200 and the plug-in terminals 302 of the second circuit board 300 to implement the circuit connection between the first circuit board 200 and the second circuit board 300. The first circuit board 200 shown in FIG. 1 is electrically connected to only one second circuit board 300 through the connector assembly 100. Of course, the first circuit board 200 may alternatively be electrically connected to multiple second circuit boards through multiple connector assemblies, respectively. The portions of the multiple connector assemblies connected to the second circuit board 300 may be fastened by using support fasteners 400.

[0053] It will be understood that the structure shown in this embodiment of the present application does not constitute a particular limitation on the electronic device 1000. In some other embodiments of the present application, the electronic device 1000 may include more or fewer components than those shown in the figures, or some components may be combined, or some components may be split, or a different component layout may exist.

[0054] Further, please refer to Fig. 2. Fig. 2 is a schematic diagram of the structure of the connector assembly 100 of the electronic device 1000 shown in Fig. 1.

[0055] The connector assembly 100 includes a connector 1a, a connector 1b, a wire 2, and a shielding layer. The shielding layer is wound around the wire 2. Both ends of the wire 2 are electrically connected to the connector 1a and the connector 1b, respectively. The connector 1a is electrically connected to a plug-in terminal of the first circuit board 200, and the connector 1b is electrically connected to a plug-in terminal 302 of the second circuit board 300, so that the first circuit board 200 is connected to the second circuit board 300 through the connector assembly 100. In this embodiment, the structures of the connector 1a and the connector 1b may be substantially the same. The following will describe the connector by using the connector 1a as an example. Of course, in another implementation, the structures of the connector 1a and the connector 1b may alternatively be different.

[0056] Please refer to Figures 3, 4, and 5. Figure 3 is a schematic diagram of a partial structure of the connector assembly 100 shown in Figure 2. Figure 4 is a schematic exploded view of the structure of the connector assembly 100 shown in Figure 3. Figure 5 is a partial cross-sectional view of the connector assembly 100 shown in Figure 4.

[0057] The connector 1a includes a metal housing 10 and a conducting piece 20. The metal housing 10 includes a shielding cavity 11 (FIG. 5). The conducting piece 20 is accommodated in the shielding cavity 11. The wire 2 is partially disposed in the shielding cavity 11 and electrically connected to one end of the conducting piece 20. At least two electrical connecting parts are disposed on the outer surface of the shielding layer 2a. The at least two electrical connecting parts face in different directions and are electrically connected respectively to parts of the metal housing 10 that the at least two electrical connecting parts face in order to reduce the crosstalk effect of the connector assembly.

[0058] In this embodiment, at least two electrical connections are arranged on the outer surface of the shielding layer 2a, the electrical connections being parts of the shielding layer 2a that are electrically connected to the metal housing 10. The electrical connections facing different directions may be connected or separated. Of course, in another embodiment, conductors may alternatively be arranged on the outer surface of the shielding layer 2a to form electrical connections to implement the electrical connection between the shielding layer 2a and the metal housing 10. Alternatively, multiple electrical connections facing different directions may be arranged on the outer surface of the shielding layer 2a, each electrical connection being electrically connected to the part of the metal housing 10 that it faces.

[0059] In the present application, the conductive part 20 is accommodated in the shield cavity 11, the wire 2 is partially disposed in the shield cavity 11 and electrically connected to one end of the conductive part 20, and at least two electrical connections on the shield layer 2a wrapped around the wire 2 face in different directions and are electrically connected to the parts of the metal housing 10 that the at least two electrical connections face, respectively. That is, the at least two electrical connections on the shield layer 2a that face in different directions are electrically connected to the peripheral walls of the shield cavity 11 that the at least two electrical connections face, respectively. Thus, when a signal returns to the wire 2 from the peripheral walls of the shield cavity 11, the signal on the peripheral walls of the shield cavity 11 is transmitted to the electrical connections on the shield layer 2a that are closer to the peripheral walls. Compared with the case where the peripheral wall of the shielding cavity 11 is electrically connected to only one electrical connection on the shielding layer 2a, the signal return path is shorter and the loop inductance is smaller, thereby effectively reducing the crosstalk effects of the connector assembly 100 (FIG. 6a is a schematic diagram of a comparison between the crosstalk in an embodiment of the present invention and the crosstalk in a conventional solution) and supporting signal transmission at rates of 112 Gbps and higher.

[0060] In this embodiment, as shown in Fig. 6b, the shield layer 2a includes a first surface 21a, a second surface 21b, a third surface 21c, and a fourth surface 21d that face different directions and are connected in sequence. The first surface 21a, the second surface 21b, the third surface 21c, and the fourth surface 21d are arranged in a circular shape to form a peripheral surface of the shield layer 2a, and at least two electricity It will be understood that the connection includes a first electrical connection and a second electrical connection, the first electrical connection extending from the first surface 21a to the third surface 21c, and the second electrical connection being disposed on the fourth surface 21d. The peripheral wall of the shield cavity 11 includes a first wall 111, a second wall 112, a third wall 113, and a fourth wall 114. The first surface 21a faces the first wall 111 and is electrically connected to the first wall 111. The second surface 21b faces the second wall 112 and is electrically connected to the second wall 112. The third surface 21c faces the third wall 113 and is electrically connected to the third wall 113. The fourth surface 21d faces the fourth wall 114 and is electrically connected to the fourth wall 114.

[0061] It will be understood that the first electrical connection portion and the second electrical connection portion are distributed together on the entire peripheral surface of the shield layer 2a so that the entire peripheral surface of the shield layer 2a can be electrically connected to the peripheral wall of the shield cavity 11. That is, the four surfaces of the shield layer 2a are electrically connected to the four peripheral walls of the shield cavity 11 corresponding to the four surfaces, respectively. Therefore, when the signal returns to the wire 2 from the four peripheral walls of the shield cavity 11, the signal on the four peripheral walls of the shield cavity 11 is transmitted to the four surfaces of the shield layer 2a close to the four peripheral walls, respectively. Compared with the case where only one of the four peripheral walls of the shield cavity 11 is electrically connected to the surface of the shield layer 2a, the signal return path is shorter and the loop inductance is smaller, thereby effectively reducing the crosstalk effect of the connector assembly 100 and supporting signal transmission at rates of 112 Gbps and higher. Of course, in another embodiment, the periphery of the shield layer 2a may alternatively be circular and at least two electrical connections may be arranged around the periphery of the shield layer 2a to form one electrical connection. Alternatively, multiple electrical connections facing different directions are arranged in different directions around the periphery of the shield layer 2a.

[0062] Please refer to Figures 5 and 7. Figure 7 is a cross-sectional view of the connector assembly 100 shown in Figure 3 in the direction AA.

[0063] In this embodiment, there are a plurality of shield cavities 11, and the plurality of shield cavities 11 form two rows of shield cavities, and the two rows of shield cavities include a first row of shield cavities 11a and a second row of shield cavities 11b. Each conductive part 20 and each wire 2 correspond to one shield cavity 11. That is, the amount of conductive parts 20 and the amount of wires 2 are the same as the amount of shield cavities 11. The plurality of conductive parts 20 form two rows of conductive parts. Each conductive part 20 and a portion of the wire 2 connected to the conductive part are arranged in a separate shield cavity 11 to separately shield each conductive part 20 and the wire 2 connected to the conductive part. This effectively reduces the effect of crosstalk between different conductive parts 20 and wires 2 connected to the conductive parts, thereby effectively reducing the effect of crosstalk in the connector assembly and supporting signal transmission at rates of 112 Gbps and higher.

[0064] Of course, in another embodiment scenario, there are at least two shielding cavities, and the at least two shielding cavities form at least two rows of shielding cavities, and the at least two rows of shielding cavities include a first row of shielding cavities and a second row of shielding cavities. In another embodiment scenario, there may alternatively be one or more shielding cavities, and the one or more shielding cavities form a row of shielding cavities.

[0065] As shown in Fig. 4, specifically, the metal housing 10 includes a first housing 12, a second housing 13, and a metal sheet 14. The metal sheet 14 is disposed between the first housing 12 and the second housing 13. The metal sheet 14 and the first housing 12 form a first row of shield cavities 11a. The metal sheet 14 and the second housing 13 form a second row of shield cavities 11b. In this embodiment, the metal sheet 14 includes a first metal sheet 14a and a second metal sheet 14b, the first metal sheet 14a is connected to the first housing 12, the second metal sheet 14b is arranged on a side of the first metal sheet 14a that lines the first housing 12 and is connected to the second housing 13, and a first row of shielding cavities 11a is formed between the first metal sheet 14a and the first housing 12, and a second row of shielding cavities 11b is formed between the second metal sheet 14b and the second housing 13. In this embodiment, the first electrical connection portion arranged in the first row of shielded cavities 11a is electrically connected to the first housing 12, the second electrical connection portion is electrically connected to the first metal sheet 14a, the first electrical connection portion arranged in the second row of shielded cavities 11b is electrically connected to the second housing 13, and the second electrical connection portion is electrically connected to the second metal sheet 14b.

[0066] It will be understood that in this embodiment, since there are two metal sheets, which together with the first housing 12 and the second housing 13 respectively form the first row of shield cavities 11a and the second row of shield cavities 11b, the two metal sheets (the first metal sheet 14a and the second metal sheet 14b) can be staggered, thereby facilitating the staggered arrangement of the two metal sheets (the first metal sheet 14a and the second metal sheet 14b) and further facilitating the staggered arrangement of the conductive components of the two rows. In this embodiment, the first housing 12, the second housing 13, the first metal sheet 14a, and the second metal sheet 14b are fixed through connection, thereby facilitating the assembly of the connector assembly 100.

[0067] Of course, in another embodiment scenario, the first housing, the second housing, the first metal sheet, and the second metal sheet may be integrated. In another scenario of another embodiment, alternatively, there may be only one metal sheet, which forms a first row of shielding cavities with the first housing and forms a second row of shielding cavities with the second housing. The locations where the first housing and the second housing are connected to the metal sheet may be set so that the first row of shielding cavities and the second row of shielding cavities are arranged opposite or staggered to each other. In this scenario, the first housing, the second housing, and the metal sheet may be integrated or fixed through the connection. In yet another scenario of another embodiment, the metal housing may alternatively include only the first housing and the second housing. The first housing and the second housing form one or more shielding cavities. The first electrical connection is electrically connected to the first housing and the second electrical connection is electrically connected to the second housing. In this scenario, the first and second housings may be integral or fixed through a connection to facilitate assembly of the connector assembly.

[0068] Please refer to Figures 4 and 8. Figure 8 is a schematic diagram of the structure of the first housing 12 of the connector assembly 100 shown in Figure 4.

[0069] In this embodiment, the first housing 12 includes a first body 121, a groove 122, an accommodation groove 123, and a plurality of partition walls 124. The first body 121 includes a first mounting surface 1210. Both the groove 122 and the accommodation groove 123 are provided on the first mounting surface 1210, and the accommodation groove 123 is disposed in the center of two sides of the groove 122 and connected to the groove 122. The plurality of partition walls 124 are disposed in the groove 122 at intervals to form a plurality of first shield grooves 125, and the first metal sheet 14a covers the openings of the first shield grooves 125 to form a first row of shield cavities 11a (FIG. 5). That is, the cavity walls 11a of the first row of shield cavities are formed by connecting the first metal sheet 14a, the partition walls 124, and the groove walls of the groove 122.

[0070] The second housing 13 covers the first housing 12, and two sides of the second housing 13 are fastened to the receiving groove 123. That is, the receiving groove 123 is configured to receive and connect the second housing 13. The receiving groove 123 is disposed in the center of two sides of the groove 122 such that a portion of the first shielding groove 125 is exposed from the second housing 13. It will be understood that since the second housing 13 does not cover a portion of the first shielding groove 125, the conductive part 20 is exposed from the metal housing 10 through this portion of the first shielding groove 125 so as to be electrically connected to an external related device. Of course, in another embodiment, the second housing may alternatively include a receiving groove, and the first housing may cover the second housing and be fastened to the receiving groove of the second housing.

[0071] The first housing 12 further includes a first wire trough 126. The first wire trough 126 penetrates the side wall of the first housing 12 facing the first shield groove 125. The first wire trough 126 is connected to the groove 122 and corresponds one-to-one with the first shield groove 125. The ends of the wires 2 disposed in the first row of shield cavities 11a lining the first shield groove 125 extend from the first housing 12 through the first wire trough 126. A fixing groove 1261 is provided in the side wall of the first housing 12 facing the first shield groove 125 and is configured to fix the second housing 13.

[0072] The first housing 12 may be integrally molded by using a process such as die casting or metal injection molding. That is, the first body 121 and the partition walls 124 are integrated together, thereby ensuring a connection structure between the first body 121 and the partition walls 124. Of course, the partition walls 124 may alternatively be fixed to the first body 121 in another connection method, such as welding.

[0073] The first shield groove 125 includes a first portion 1251 and a second portion 1252 connected to the first portion 1251. The first portion 1251 is exposed from the second housing 13. The groove bottom wall of the first portion 1251 gradually approaches the first mounting surface 1210 in a direction away from the second portion 1252. The groove bottom wall of the second portion 1252 is the groove bottom wall of the groove 122. That is, the groove bottom wall of the first portion 1251 is inclined with respect to the groove bottom wall of the second portion 1252 so as to fit the shapes of the conductive component 20 and the wire 2. Of course, in another embodiment, the first portion 1251 and the second portion 1252 may alternatively be located on the same horizontal plane.

[0074] In this embodiment, the groove bottom wall of the receiving groove 123 and the partition wall 124 located in the second part 1252 are located on the same horizontal plane, a limiting notch 1231 is provided in the receiving groove 123, a fixing post 1241 is disposed on the surface of the partition wall 124 lining the groove bottom wall of the groove 122, the first metal sheet 14a covers the opening of the second part 1252, the first metal sheet 14a is limited by the fixing post 1241, and the two sides of the first metal sheet 14a are limited in the limiting notch 1231 of the receiving groove 123 corresponding to the two sides. Of course, in another embodiment, the first metal sheet 14a may alternatively cover the entire opening of the first shield groove 125.

[0075] The connector assembly 100 further includes limiting blocks 127. A quantity of limiting blocks 127 corresponds to a quantity of first shielding grooves 125. Each limiting block 127 is disposed in the first shielding groove 125 corresponding to the limiting block, and is disposed at an end of the first portion 1251 remote from the second portion 1252. The end of the conductive part 20 disposed in the shielding cavity 11a of the first row remote from the wire 2 is disposed on the limiting block 127. Specifically, the limiting block 127 is made of an insulating material, and the end of the conductive part 20 remote from the wire 2 may be partially embedded in the surface of the limiting block 127 lining the first shielding groove 125, or may be disposed on the surface of the limiting block 127 lining the first shielding groove 125. The limiting block 127 limits the conductive part 20 to avoid deformation of the conductive part 20 during use. In addition, the limiting block 127 can further prevent the conductive part 20 from being electrically connected to the groove wall of the first shielding groove 125, thereby improving the life span of the connector assembly 100 and improving the safety performance of the connector assembly 100.

[0076] Please refer to Figures 3 and 9. Figure 9 is a schematic diagram of a partial structure of the connector assembly 100 shown in Figure 4.

[0077] The first metal sheet 14a includes a limiting structure 141, a via 142, and a conductive part 143. The limiting structure 141 is in one-to-one correspondence with the limiting notch 1231, and the via 142 is in one-to-one correspondence with the fixing post 1241. The limiting structure 141 is disposed on two opposite sides of the first metal sheet 14a. The via 142 penetrates the two opposite surfaces of the first metal sheet 14a. The limiting structure 141 is configured to fit with the limiting notch 1231 corresponding to the limiting structure, and is clamped between the second housing 13 and the adjustment groove 123. The fixing post 1241 passes through the via 142 corresponding to the fixing post to position and fix the first metal sheet 14a. The conductive part 143 is disposed on the surface of the first metal sheet 14a facing the first shielding groove 125, and is configured to be electrically connected to the shielding layer 2a of the wire 2. In this embodiment, the conductive portion 143 is an elastomer. Because the elastomer is elastic, the first metal sheet 14a can be electrically connected to the wire 2, and the wire 2 can abut against the groove wall of the first shield groove 125, thereby ensuring a good electrical connection between the shield layer 2a of the wire 2 and the groove wall of the first shield groove 125, and effectively reducing the crosstalk of the connector assembly 100. Of course, in another embodiment, the first metal sheet 14a may alternatively be connected to the first housing 12 by using a screw or in another manner. Alternatively, the conductive portion 143 may be a convex hull, and the convex hull abuts against the second electrical connection portion.

[0078] In this embodiment, the first metal sheet 14a is an integral structure obtained through integral molding to ensure the connection strength of the first metal sheet 14a. Of course, the conductive portion 143 may be fixed to the surface of the first metal sheet 14a through bonding, clamping, or welding. In another embodiment scenario, the first metal sheet only includes the limiting structure and the via, and the first metal sheet may be electrically connected to the shielding layer of the wire through welding, etc. In yet another embodiment scenario, a conductive material may be further added between the first metal sheet and the shielding layer of the wire to implement the electrical connection between the first metal sheet and the shielding layer of the wire.

[0079] See Figures 9 and 10. Figure 10 is a schematic diagram of a partial structure of the connector assembly 100 shown in Figure 4.

[0080] The conductive parts 20 have contact parts 21 and connection parts 22 connected to each other. The connection parts 22 are electrically connected to the wires 2. The contact parts 21 located in the first row of shield cavities 11a are located in the first parts 1251 of the first shield grooves 125. One end of the contact parts 21 is embedded in the surface of the limiting block 127 to limit the contact parts 21. The contact parts 21 are exposed from the surface of the second housing 13 lining the first housing 12. That is, since the contact parts 21 are exposed from the second housing 13, the contact parts 21 are electrically connected to an external related device. The connection parts 22 and a part of the wires 2 are disposed in the second parts 1252. That is, the connection parts 22 of the conductive parts 20 and the part of the wires 2 connected to the conductive parts 20 are disposed in the shield cavities 11, thereby effectively reducing the effect of crosstalk of the connector assembly 100 and supporting signal transmission at rates of 112 Gbps and higher.

[0081] In this embodiment, each conductive part 20 includes two conductive terminals 20a, and correspondingly, each wire 2 includes two signal lines. The two conductive terminals 20a are electrically connected to the signal lines corresponding to the two conductive terminals, respectively. The two conductive terminals 20a are embedded separately in the limit block 127 at intervals, thereby effectively preventing electrical connection between the two conductive terminals 20a during use. Of course, in another embodiment, each conductive part 20 may alternatively include more than two conductive terminals. In addition to the conductive terminals for transmitting signals, a conductive terminal used for grounding may further be included. The conductive terminal used for grounding is electrically connected to the first housing, thereby further reducing the effect of crosstalk in the connector assembly and supporting signal transmission at rates of 112 Gbps and higher.

[0082] The connector assembly 100 further includes an insulator 30, which is wound around the conductive parts 20 at the locations where the connection parts 22 are adjacent to the contact parts 21. Specifically, the insulator 30 is disposed at the locations where the connection parts 22 of each conductive part 20 are adjacent to the contact parts 21, and the insulator 30 is wound around the conductive parts 20 to fix the two conductive terminals 20a of the conductive parts 20. In addition, the insulator 30 can further separate the conductive parts 20 from the first shield groove 125 or separate the conductive parts 20 from the cavity walls of the second row of the shield cavity 11b to prevent electrical connection between the conductive parts 20 and the groove walls of the first shield groove 125 or the cavity walls of the second row of the shield cavity 11b.

[0083] The insulator 30 may further include a positioning pin 31. For example, the positioning pin 31 may be arranged on a surface of the insulator 30 located in a first row of the shield cavity 11a facing the first metal sheet 14a, in which case the positioning pin 31 may penetrate and limit the first metal sheet 14a. The positioning pin 31 may be arranged on a surface of the insulator 30 located in a second row of the shield cavity 11b facing the second metal sheet 14b, in which case the positioning pin 31 may penetrate and limit the second metal sheet 14b.

[0084] 5 and 8, the ends of the wires 2 arranged in the first row of the shielding cavity 11a, which is remote from the conductive parts 20, extend from the first housing 12 through the first wire trough 126. A portion of the wires 2 arranged in the shielding cavity 11a is embedded in the first shielding groove 125, so that a first electrical connection on the shielding layer 2a facing the groove wall of the first shielding groove 125 is attached to the groove wall. The conductive portion 143 abuts a second electrical connection on the shielding layer 2a lining the first shielding groove 125.

[0085] It will be understood that all the peripheral surfaces of the shield layer 2a are electrically connected to the peripheral wall of the shield cavity 11 that they face. Thus, when the signal returns to the wire 2 from the peripheral wall of the shield cavity 11, the signal on the peripheral wall of the shield cavity 11 is transmitted to the first electrical connection and the second electrical connection on the shield layer 2a close to the peripheral wall. The signal return path is shorter and the loop inductance is smaller, thereby effectively reducing the crosstalk effect of the connector assembly 100 and supporting signal transmission at rates of 112 Gbps and higher.

[0086] In this embodiment, the shape of the first electrical connection on the shield layer 2a facing the groove wall of the first shield groove 125 is the same as the shape of the groove wall, so that the first electrical connection on the shield layer 2a facing the groove wall of the first shield groove 125 is closely attached to the groove wall of the first shield groove 125. In this way, good electrical connection is implemented between the first electrical connection on the three surfaces of the shield layer 2a and the groove wall of the first shield groove 125, thereby effectively reducing the crosstalk of the connector assembly 100. Of course, in another embodiment, the part of the wire disposed in the shield cavity is disposed in the first shield groove, but conductive material is added between the shield layer and the groove wall of the first shield groove, and between the shield layer and the first metal sheet, to implement the electrical connection between the shield cavity and the shield layer.

[0087] Please refer to Figures 10 and 11. Figure 11 is a schematic exploded view of the structure of the connector assembly 100 shown in Figure 4.

[0088] The connector assembly 100 further includes a fastener 40. The fastener 40 is wound around the joint between the connection portion 22 and the wire 2, and fixes the wires 2 arranged in the same row of the shield cavity 11. Specifically, there are two fasteners 40. One fastener 40 is wound around the joint between the connection portion 22 and the wire 2 in the first row of the shield cavity 11a, and fixes all the wires 2 arranged in the first row of the shield cavity 11a. One fastener 40 is wound around the joint between the connection portion 22 and the wire 2 in the second row of the shield cavity 11b, and fixes all the wires 2 in the second row of the shield cavity 11b. The fastener 40 can protect the solder joint between the conductive part 20 and the wire 2. In addition, in order to quickly assemble the connector assembly 100, the fastener 40 can be used to fix multiple conductive parts 20 and multiple wires 2 arranged in the same row to form a transmission plate. This effectively improves the manufacturing efficiency of the connector assembly 100 and reduces the manufacturing cost of the connector assembly 100 .

[0089] Please refer to Figures 4, 11 and 12. Figure 12 is a schematic diagram of the structure of the second metal sheet 14b of the connector assembly 100 shown in Figure 11.

[0090] The second metal sheet 14b includes a flat section 144 and a bent section 145 connected to the flat section 144. A support pad 146 is disposed on the surface of the bent section 145 facing the first metal sheet 14a. The surface of the support pad 146 facing the first metal sheet 14a is flush with the surface of the flat section 144 facing the first metal sheet 14a so that the second metal sheet 14b can be disposed on the first metal sheet 14a. Specifically, a positioning groove 1461 is provided on each surface of the support pad 146 and the flat section 144 facing the first metal sheet 14a. The fastening post 1241 passing through the via 142 of the first metal sheet 14a is received in the positioning groove 1461 corresponding to the fastening post, thereby restricting the second metal sheet 14b on the first metal sheet 14a. In this embodiment, the support pad 146 is configured to support the bending section 145 and also increases the area of ​​the connection between the second metal sheet 14b and the first metal sheet 14a so that the second metal sheet 14b can be more stably restrained on the first metal sheet 14a.

[0091] The limiting block 147 is arranged on the surface of the bent section 145 of the second metal sheet 14b backing the support pad 146, and the limiting block 147 is arranged at the end of the bent section 145 away from the flat section 144. The contact portion 21 of the conductive component 20 arranged in the shielding cavity 11b of the second row is arranged on the side of the bent section 145 backing the support pad 146. The connection portion 22 of the conductive component 20 and a part of the wire 2 connected to the connection portion 22 are arranged on the side of the flat section 144 backing the first metal sheet 14a. The end of the contact portion 21 away from the connection section 22 is arranged on the limiting block 147. Specifically, the limiting block 147 is made of an insulating material, and the end of the contact portion 21 away from the connection portion 22 may be partially embedded in the surface of the limiting block 147 backing the first shielding groove 125, or may be arranged on the surface of the limiting block 147 backing the second metal sheet 14b. The limiting block 147 limits the conductive part 20 to avoid deformation of the contact portion 21 during use. In addition, the limiting block 147 can further prevent the contact portion 21 from being electrically connected to the second metal sheet 14b, thereby improving the service life of the connector assembly 100 and improving the safety performance of the connector assembly 100.

[0092] The second metal sheet 14b further includes a via 148, a conductive portion 149, and a clamping groove 140. The via 148 and the conductive portion 149 are provided in the flat section 144 at intervals. The conductive portion 149 is disposed at a location backing the surface of the first metal sheet 14a. The clamping groove 140 is provided in the bent section 145 and configured to fit with the second housing 13. The positioning pin 31 of the insulator 30 disposed in the shielding cavity 11b of the second row is received in the via 148 for positioning the transmission plate. The conductive portion 149 is configured to be electrically connected to the shielding layer 2a of the wire 2. The conductive portion 149 is configured to be electrically connected to the shielding layer 2a of the wire 2. 49 may be an elastomer. Since the elastomer is elastic, the second metal sheet 14b can be electrically connected to the wire 2, and the wire 2 can abut against the second housing 13, thereby ensuring a good electrical connection between the shield layer 2a of the wire 2 and the second housing 13, and effectively reducing the crosstalk of the connector assembly 100. In this embodiment, the second metal sheet 14b is an integral structure obtained through integral molding to ensure the connection strength of the second metal sheet 14b. Of course, the conductive part 149 may be fixed to the surface of the second metal sheet 14b through bonding, clamping, or welding. Alternatively, the conductive part 149 may be a convex shell structure, and the convex shell structure abuts against the second electrical connection part.

[0093] Please refer to Figures 11 and 13. Figure 13 is a schematic diagram of the structure of the second housing 13 of the connector assembly 100 shown in Figure 11.

[0094] The second housing 13 includes a second body 131 and a plurality of partition plates 132. The second body 131 includes a second mounting surface 1310. The second mounting surface 1310 faces the first housing 12. The plurality of partition plates 132 are arranged at intervals on the second mounting surface 1310. That is, the plurality of partition plates 132 are arranged at intervals on the surface of the second housing 13 facing the first housing 12, and form a plurality of second shield grooves 133 having the second mounting surface 1310 (the surface of the second housing 13 facing the first housing 12). The second metal sheet 14b covers the opening of the second shield groove 133. That is, the second housing 13 is arranged on the side of the second metal sheet 14b backing the first metal sheet 14a so as to form a second row of shield cavities 11b.

[0095] The second housing 13 further includes a plurality of partition posts 134. The plurality of partition posts 134 are spaced apart from each other on an edge of the second mounting surface 1310 facing the second shield groove 133. The plurality of partition posts 134 and the second mounting surface 1310 form a plurality of second wire troughs 135. The second wire troughs 135 correspond one-to-one with the second shield grooves 133. The ends of the wires 2 disposed in the second row of shield cavities 11b lining the second shield grooves 133 extend from the second housing 13 through the second wire troughs 135. A fastening protrusion 1341 is disposed on the partition post 134, and the fastening protrusion 1341 is fixed in a fastening groove 1261 of the first housing 12 corresponding to the fastening protrusion 1341 so as to be fixed to the first housing 12. In this embodiment, the second wire trough 135 is connected to the first wire trough 126. Of course, in other embodiments, the first wire trough 126 may alternatively not be connected to the second wire trough 135.

[0096] The second housing 13 may be integrally molded by using a process such as die casting or metal injection molding. That is, the second body 131, the partition plates 132 and the partition posts 134 are integrated together, thereby ensuring a connection structure between the second body 131 and the partition plates 132. Of course, the partition plates 132 and the partition posts 134 may alternatively be fixed to the second body 131 by another connection method such as welding.

[0097] The second shield groove 133 includes a third portion 1331 and a fourth portion 1332 connected to the third portion 1331. The contact portion 21 of the conductive component 20 arranged in the shield cavity 11b of the second row is arranged in the third portion 1331. The connection portion 22 of the conductive component 20 and a portion of the wire 2 connected to the connection portion 22 are located in the fourth portion 1332. Since the third portion 1331 includes an opening 1333, the contact portion 21 of the conductive component 20 is exposed from the second housing 13 through the opening 1333. The surface of the partition plate 132 arranged in the third portion 1331 facing the first housing 12 gradually moves away from the first housing 12 in a direction away from the fourth portion 1332. That is, the surface of the partition plate 132 located at the third portion 1331 facing the first housing 12 is an inclined surface, and the surface of the partition plate 132 located at the fourth portion 1332 facing the first housing 12 is a flat surface. Therefore, the third portion 1331 is connected to the bent section 145 of the second metal sheet 14b, and the fourth portion 1332 is connected to the flat section 144 of the second metal sheet 14b.

[0098] In this embodiment, the fixing post 1321 and the convex bar 1322 are disposed on the surface of the partition plate 132 facing the second metal sheet 14b. The convex bar 1322 is located in the third portion 1331, and the fixing post 1321 is located in the fourth portion 1332. The convex bar 1322 is clamped (fastened) in the clamping groove 140 (FIG. 12) corresponding to the convex bar, and the fixing post 1321 fits with the second metal sheet 14b such that the second housing 13 is fixed to the second metal sheet 14b. In another embodiment scenario, the second metal sheet 14b may alternatively be connected to the second housing 13 by using screws or in another manner.

[0099] The portion of the wire 2 located in the shielding cavity 11 of the second row located in the shielding cavity 11 is embedded in the second shielding groove 133 such that the first electrical connection on the shielding layer 2a facing the groove wall of the second shielding groove 133 is attached to the groove wall. The conductive portion 149 of the second metal sheet 14b abuts the second electrical connection on the shielding layer 2a lining the second shielding groove 133. That is, the first electrical connection and the second electrical connection on the shielding layer 2a are electrically connected to the peripheral wall of the shielding cavity 11 that the first electrical connection and the second electrical connection face, respectively. Thus, when the signal returns from the peripheral wall of the shielding cavity 11 to the wire 2, the signal on the peripheral wall of the shielding cavity 11 is transmitted to the first electrical connection and the second electrical connection on the shielding layer 2a close to the peripheral wall. The signal return path is shorter and the loop inductance is smaller, thereby effectively reducing the effects of crosstalk in the connector assembly 100 and supporting signal transmission at rates of 112 Gbps and higher.

[0100] In this embodiment, the shape of the first electrical connection on the shield layer 2a facing the groove wall of the second shield groove 133 is the same as the shape of the groove wall of the second shield groove 133, so that the first electrical connection on the shield layer 2a facing the groove wall of the second shield groove 133 is closely attached to the groove wall of the second shield groove 133. In this way, a good electrical connection is implemented between the first connection on the three surfaces of the shield layer 2a and the groove wall of the second shield groove 133, thereby effectively reducing the crosstalk of the connector assembly 100. Of course, in another embodiment, the part of the wire disposed in the shield cavity is disposed in the second shield groove, but a conductive material is added between the shield layer and the groove wall of the second shield groove and between the shield layer and the second metal sheet to implement the electrical connection between the shield cavity and the shield layer.

[0101] Please refer to Figures 14 and 15. Figure 14 is a schematic diagram of the structure of a second embodiment of a connector assembly 100 according to this embodiment. Figure 15 is a schematic cross-sectional view of the structure of the connector assembly 100 shown in Figure 14 in the BB direction.

[0102] This embodiment is almost the same as the first embodiment. The difference lies in that the metal housing 10 of this embodiment includes a first housing 12 and a second housing 13, and the second housing 13 is buckled to the first housing 12 to form a shielding cavity 11. The first housing 12 in this embodiment has the same structure as that of the first housing 12 in the first embodiment. The second housing 13 is a plate body, and the second housing 13 covers the first housing 12 and covers the opening of the first shielding groove 125 (FIG. 8) to form a plurality of shielding cavities 11. In this embodiment, the shielding cavities 11 are arranged in only one row, and the cavity wall of each shielding cavity of the plurality of shielding cavities 11 is formed by connecting the second housing 13, the partition wall 124, and the groove wall of the groove 122.

[0103] The second housing 13 covers the first housing 12, and two sides of the second housing 13 are fixed in the receiving groove 123. That is, the receiving groove 123 is configured to receive and connect the second housing 13. Since the second housing 13 does not cover a portion of the first shielding groove 125, the conductive part 20 is exposed from the metal housing 10 through this portion of the first shielding groove 125 so as to be electrically connected to an external related device.

[0104] The end of the wire 2 that is away from the conductive part 20 extends from the first housing 12 through a first wire trough. A portion of the wire 2 located in the shielding cavity 11 is embedded in the first shielding groove 125 such that a first electrical connection on the shielding layer 2a facing the groove wall of the first shielding groove 125 is attached to the groove wall. The conductive portion 136 may be arranged on a surface of the second housing 13 facing the first housing 12 and may abut a second electrical connection on the shielding layer 2a lining the first shielding groove 125. The conductive portion 136 may be an elastomer or may have a convex structure, such as a convex shell structure. That is, the first and second electrical connections on the shielding layer 2a are electrically connected to the peripheral walls of the shielding cavity 11 that the first and second electrical connections face, respectively. Therefore, when the signal returns to the wire 2 from the peripheral wall of the shield cavity 11, the signal on the peripheral wall of the shield cavity 11 is transmitted to the first electrical connection and the second electrical connection on the shield layer 2a close to the peripheral wall. The signal return path is shorter and the loop inductance is smaller, thereby effectively reducing the crosstalk effect of the connector assembly 100 and supporting signal transmission at rates of 112 Gbps and higher.

[0105] In this embodiment, the shape of the first electrical connection on the shield layer 2a facing the groove wall is the same as the shape of the groove wall, so that the first electrical connection on the shield layer 2a facing the groove wall of the first shield groove 125 is closely attached to the groove wall of the first shield groove 125. In this way, a good electrical connection is implemented between the first electrical connection on the three surfaces of the shield layer 2a and the groove wall of the first shield groove 125, thereby effectively reducing the crosstalk of the connector assembly 100. Of course, in another embodiment, the part of the wire located in the shield cavity is disposed in the first shield groove, but a conductive material is added between the shield layer and the groove wall of the first shield groove and between the shield layer and the second housing to implement the electrical connection between the shield cavity and the shield layer.

A manufacturing method is used to manufacture the connector assembly 100, and the manufacturing method for the connector assembly 100 includes the following steps S110 and S120.

[0107] S110: Electrically connect the conductive component 20 to the wire 2 to form a transmission component 50, in which a shielding layer 2a is wrapped around the wire 2 and at least two electrical connections are disposed on an outer surface of the shielding layer 2a, the at least two electrical connections facing in different directions.

Next, the conductive part 20 is stamped (punched out) so that the contact portion 21 is bent toward the connection portion 22. Next, as shown in FIG. 18, injection molding is performed on each conductive part to form an insulator 30 wrapped around the conductive part 20 at a location where the connection portion 22 of the conductive part 20 is adjacent to the contact portion 21. The material of the insulator 30 can be, for example, a liquid crystal polymer ( L The material may be a plastic having good fluidity such as CP. Two conductive terminals 20a are fixed at a distance by using an insulator 30.

Each wire 2 is electrically connected to a conductive part 20 corresponding to the wire. Specifically, the connection portion 22 of the conductive part 20 is electrically connected to the signal line of the wire 2 to form a transmission part 50.

[0110] Finally, as shown in Figures 20 and 21, a plurality of transmission parts 50 are arranged in a row, and a fastener 40 wrapped around the joint between the conductive part 20 and the wire 2 is formed through low pressure injection molding, so that the plurality of transmission parts 50 form a modular transmission plate 60. The fastener 40 is usually made of a low pressure adhesive such as polypropylene or polyethylene to protect the joint between the conductive part 20 and the wire 2 and to fix the plurality of transmission parts 50.

[0111] In this embodiment, two rows of transmission plates 60 are formed. For ease of distinction, the two transmission plates 60 are a first transmission plate 60a and a second transmission plate 60b. Of course, in another embodiment, one or more rows of transmission plates may alternatively be formed. Alternatively, the multiple transmission parts 50 may exist independently, i.e., the multiple transmission parts 50 may not be formed through injection molding.

[0112] S120: Providing a metal housing 10, and mounting a transmission component 50 within a shielded cavity of the metal housing 10, wherein the at least two electrical connections are respectively electrically connected to portions of the metal housing 10 facing the at least two electrical connections.

In this embodiment, the first housing 12 and the second housing 13 are integrally molded by using a process such as die casting or metal injection molding to ensure the connection strength of the first housing 12 and the second housing 13, respectively. Of course, in another embodiment, the first housing 12 and the second housing 13 may alternatively be formed through assembly by using another process.

[0114] As shown in FIG. 8, the first housing 12 includes a first body 121, a groove 122, an accommodation groove 123, a plurality of partition walls 124, and a first wire trough 126. The first body 121 includes a first mounting surface 1210. Both the groove 122 and the accommodation groove 123 are provided on the first mounting surface 1210, and the accommodation groove 123 is disposed on two sides of the groove 122 and connected to the groove 122. The plurality of partition walls 124 are spaced apart in the groove 122 to form a plurality of first shield grooves 125. The first wire trough 126 penetrates a side wall of the first housing 12 facing the first shield groove 125. The first wire trough 126 is connected to the groove 122 and corresponds one-to-one with the first shield groove 125.

[0115] The first shield groove 125 includes a first portion 1251 and a second portion 1252 connected to the first portion 1251. A groove bottom wall of the first portion 1251 gradually approaches the first mounting surface 1210 in a direction away from the second portion 1252. The groove bottom wall of the second portion 1252 is the groove bottom wall of the groove 122. That is, the groove bottom wall of the first portion 1251 is inclined with respect to the groove bottom wall of the second portion 1252 so as to fit the shapes of the conductive component 20 and the wire 2.

[0116] In this embodiment, the groove bottom wall of the receiving groove 123 and the partition wall 124 located at the second portion 1252 are located on the same horizontal plane, a limiting notch 1231 is provided in the receiving groove 123, and a fixing post 1241 is disposed on the surface of the partition wall 124 lining the groove bottom wall of the groove 122. An end of the first portion 1251 of each first shielding groove 125 remote from the second portion 1252 is disposed on a limiting block 147, and the limiting block 147 is formed of an insulating material.

[0117] As shown in FIG. 13, the second housing 13 includes a second body 131, a plurality of partition plates 132, and a plurality of partition posts 134. The second body 131 includes a second mounting surface 1310. The second mounting surface 1310 faces the first housing 12. The plurality of partition plates 132 are spaced apart on the second mounting surface 1310. That is, the plurality of partition plates 132 are spaced apart on the surface of the second housing 13 facing the first housing 12, and form a plurality of second shield grooves 133 together with the second mounting surface 1310. The plurality of partition posts 134 are spaced apart on an edge of the second mounting surface 1310 facing the second shield groove 133. The plurality of partition posts 134 and the second mounting surface 1310 form a plurality of second wire troughs 135. The second wire troughs 135 correspond one-to-one to the second shield grooves 133 .

[0118] The second shield groove 133 includes a third portion 1331 and a fourth portion 1332 connected to the third portion 1331. The third portion 1331 has an opening 1333. The surface of the partition plate 132 located in the third portion 1331 facing the first housing 12 gradually moves away from the first housing 12 in a direction away from the fourth portion 1332. That is, the surface of the partition plate 132 located in the third portion 1331 facing the first housing 12 is an inclined surface, and the surface of the partition plate 132 located in the fourth portion 1332 facing the first housing 12 is a flat surface. In this embodiment, the fixing post 1321 and the convex bar 1322 are disposed on the surface of the partition plate 132 facing the second metal sheet 14b. The convex bar 1322 is disposed in the third portion 1331, and the fixing post 1321 is disposed in the fourth portion 1332.

[0119] Next, as shown in FIG. 12 and FIG. 22, a metal sheet 14 is provided. The metal sheet 14 includes a first metal sheet 14a and a second metal sheet 14b. In this embodiment, the first metal sheet 14a, the second metal sheet 14b, the first housing 12, and the second housing 13 together constitute a metal housing. The first metal sheet 14a includes a limiting structure 141, a via 142, and a conductive portion 143. The second metal sheet 14b includes a flat section 144 and a bent section 145 connected to the flat section 144. A support pad 146 is disposed on a surface of the bent section 145 that backs the flat section 144. The support pad 146 is configured to support the bent section 145. The surface of the support pad 146 that backs the bent section 145 is flush with the surface of the flat section 144, so that the second metal sheet 14b can be disposed on the first metal sheet 14a. In this embodiment, the conductive portion 143 is an elastomer. Of course, the conductive portion may alternatively be a convex structure, such as a convex shell structure.

[0120] Specifically, a positioning groove is provided on each surface of the support pad 146 and the flat section 144 facing the first metal sheet 14a. A limiting block 147 is arranged on the surface of the bent section 145 of the second metal sheet 14b backing the support pad 146. The limiting block 147 is made of an insulating material, and the limiting block 147 is located at the end of the bent section 145 away from the flat section 144. The second metal sheet 14b further includes a via 148, a conductive portion 149, and a clamping groove 140. The via 148 and the conductive portion 149 are provided on the flat section 144 at intervals. The clamping groove 140 is arranged in the bent section 145 and is configured to fit with the second housing 13. In this embodiment, the conductive portion 149 is an elastomer. Of course, the conductive portion may alternatively be a convex structure, such as a convex shell structure.

[0121] Mounting the transmission component 50 in the shield cavity of the metal housing particularly includes first mounting the first metal sheet 14a to the first transmission plate 60a and mounting the second metal sheet 14b to the second transmission plate 60b, as shown in Figures 22 and 23. Specifically, the first metal sheet 14a is disposed on the surface in the bending direction of the contact portion 21 of the first transmission plate 60a, the first metal sheet 14a is clamped by the first transmission plate 60a, the first metal sheet 14a covers the connection portion 22 of the conductive component 20 and a part of the wire 2, and the conductive portion 143 of the first metal sheet 14a abuts and is electrically connected to the shield layer 2a on the outer surface of the wire 2.

[0122] In addition, the second metal sheet 14b is arranged on a surface backing the contact portion 21 of the second transmission plate 60b in the bending direction, the second metal sheet 14b is clamped with the second transmission plate 60b, the second metal sheet 14b covers the conductive part 20 and a part of the wire 2, the conductive part 149 of the second metal sheet 14b abuts and is electrically connected to the shield layer 2a on the outer surface of the wire 2, and the end of the contact portion 21 of the conductive part 20 of the second transmission plate 60b remote from the connection portion 22 is arranged on the limiting block 147. The end of the contact portion 21 remote from the connection portion 22 may be partially embedded in the surface of the limiting block 147 backing the first shield groove 125, or may be arranged on the surface of the limiting block 147 backing the second metal sheet 14b. The limiting block 147 limits the conductive part 20 to avoid deformation of the contact portion 21 during use. In addition, the limiting block 147 can further prevent the contact portion 21 from being electrically connected to the second metal sheet 14b, thereby improving the service life of the connector assembly and improving the safety performance of the connector assembly.

[0123] In another embodiment scenario, the first metal sheet and the second metal sheet may alternatively be electrically connected to the shielding layer of the wires of the first transmission plate and the second transmission plate, respectively, by using screws or in another manner. In another embodiment scenario, the first metal sheet and the second metal sheet may alternatively be electrically connected to the shielding layer of the wires, respectively, through welding. Alternatively, a conductive material may be added between the first metal sheet and the shielding layer to implement an electrical connection between the first metal sheet and the shielding layer corresponding to the first metal sheet, and a conductive material may be added between the second metal sheet and the shielding layer to implement an electrical connection between the second metal sheet and the shielding layer corresponding to the second metal sheet.

[0124] Next, as shown in FIG. 8 and FIG. 24, the first transmission plate 60a to which the first metal sheet 14a is attached is attached to the first housing 12. Specifically, the first transmission plate 60a is attached to the groove 122 of the first housing 12 with the side of the first transmission plate 60a backing the first metal sheet 14a facing the first housing 12, the conductive part 20 and a portion of the wire 2 of the first transmission plate 60a are disposed in the first shield groove 125, the contact portion 21 of the conductive part 20 is disposed in the first portion 1251, the end of the contact portion 21 remote from the connection portion 22 is disposed in the limit block 147, and the connection portion 22 of the conductive part 20 and a portion of the wire 2 are located in the second portion 1252. The end of the wire 2 remote from the conductive part 20 extends from the first housing 12 through the first wire trough 126.

[0125] In this embodiment, the end of the contact portion 21 remote from the connection portion 22 may be partially embedded in the surface of the limiting block 147 lining the first shielding groove 125, or may be disposed on the surface of the limiting block 147 lining the first shielding groove 125. The limiting block 147 limits the conductive part 20 to avoid deformation of the conductive part 20 during use. In addition, the limiting block 147 can further prevent the conductive part 20 from being electrically connected to the groove wall of the first shielding groove 125, thereby improving the service life of the connector assembly and improving the safety performance of the connector assembly.

[0126] The first metal sheet 14a covers the openings of the second parts 1252 of the multiple first shielding grooves 125 of the first housing 12, and the two sides of the first metal sheet 14a are restricted in the restricting notches 1231 of the receiving grooves 123 corresponding to the two sides. The fixing posts 1241 on the partition wall 124 pass through the vias 142 of the first metal sheet 14a to restrict the first metal sheet 14a. The first metal sheet 14a and the second shielding grooves 133 form multiple shielding cavities. The transmission components 50 of the first transmission plate 60a are located in the shielding cavities of the metal housing. The first electrical connection on the shielding layer 2a of the wire 2 of the first transmission plate 60a is electrically connected to the first housing 12, and the second electrical connection is electrically connected to the first metal sheet 14a.

[0127] It will be understood that since a portion of the wire 2 located in the shielding cavity is embedded in the first shielding groove 125, the first electrical connection on the shielding layer 2a facing the groove wall of the first shielding groove 125 is attached to the groove wall. The conductive portion 143 of the first metal sheet 14a abuts the second electrical connection on the shielding layer 2a lining the first shielding groove 125. Thus, when the signal returns from the peripheral wall of the shielding cavity to the wire 2, the signal on the peripheral wall of the shielding cavity is transmitted to the first electrical connection and the second electrical connection on the shielding layer 2a close to the peripheral wall. The signal return path is shorter and the loop inductance is smaller, thereby effectively reducing the crosstalk effect of the connector assembly and supporting signal transmission at rates of 112Gbps and higher.

[0128] 4 and 24, the second transmission plate 60b to which the second metal sheet 14b is attached is attached to the side of the first metal sheet 14a backing the first housing 12. Specifically, the surface of the second metal sheet 14b backing the second transmission plate 60b is placed on the first metal sheet 14a, and the fixing post 1241 penetrating the first metal sheet 14a is received in the positioning groove 1461 corresponding to the fixing post to restrict the second metal sheet 14b on the first metal sheet 14a.

[0129] Finally, as shown in Figures 13 and 24, the second housing 13 is attached to the first housing 12 with the second mounting surface 1310 facing the first housing 12 to form the connector assembly 100 (Figure 3). Specifically, the second shield groove 133 of each of the second housings 13 is wrapped around a portion of the conductive part 20 and the wire 2 on the second transmission plate 60b corresponding to the second shield groove 133 and abuts against the second metal sheet 14b to enclose the multiple shield cavities with the second metal sheet 14b. The end of the wire 2 remote from the conductive part 20 extends from the second housing 13 through the second wire trough 135.

[0130] Specifically, the second housing 13 covers the first housing 12, and two sides of the second housing 13 are fixed in the receiving groove 123. The second housing 13 may be fixed to the first housing 12 through clamps, screw fastening, etc. A portion of the first shielding groove 125 is exposed from the second housing 13. It will be understood that since the second housing 13 does not cover a portion of the first shielding groove 125, the conductive component 20 located on the first transmission plate 60a is exposed from the metal housing 10 through this portion of the first shielding groove 125 so as to be electrically connected to an external related device.

[0131] The convex bar 1322 on the second housing 13 is clamped in the clamp groove 140 on the second metal sheet 14b corresponding to the convex bar. The fixing post 1321 of the second housing 13 passes through the via 148 of the second metal sheet 14b to position the second housing 13 and the second metal sheet 14b and fix the second metal sheet 14b and the second housing 13. The contact portion 21 of the conductive part 20 is exposed from the second housing 13 through the opening 1333 of the second housing 13. The flat section 144 of the second metal sheet 14b covers the opening 133 of the second shield groove 133. The transmission part 50 of the second transmission plate 60b is located in the shield cavity of the metal housing 10. In addition, a first electrical connection on the shielding layer 2a is electrically connected to the second housing 13 and a second electrical connection is electrically connected to the second metal sheet 14b.

[0132] It will be understood that since a portion of the wire 2 of the second transmission plate 60b located in the shielding cavity is embedded in the second shielding groove 133, the first electrical connection on the shielding layer 2a facing the groove wall of the second shielding groove 133 is attached to the groove wall. The conductive portion 149 of the second metal sheet 14b abuts the second electrical connection on the shielding layer 2a lining the second shielding groove 133. Thus, when the signal returns from the peripheral wall of the shielding cavity to the wire 2, the signal on the peripheral wall of the shielding cavity is transmitted to the first electrical connection and the second electrical connection on the shielding layer 2a close to the peripheral wall. The signal return path is shorter and the loop inductance is smaller, thereby effectively reducing the crosstalk effect of the connector assembly 100 and supporting signal transmission at rates of 112 Gbps and higher.

[0133] In this embodiment, first, the first metal sheet 14a is attached to the first transmission plate 60a, the second metal sheet 14b is attached to the second transmission plate 60b, then the first metal sheet 14a and the second transmission plate 60b are attached to the first housing 12, and the second metal sheet 14b and the second transmission plate 60b are attached to the first housing 12. That is, in this embodiment, different elements of the connector assembly 100 are modularized and then assembled, thereby effectively improving the assembly efficiency of the connector assembly 100, improving the manufacturing efficiency of the connector assembly 100, and reducing the manufacturing cost.

[0134] Of course, in another embodiment scenario, the first metal sheet is not pre-mounted on the first transmission plate, and the second metal sheet is not pre-mounted on the second transmission plate. First, the first transmission plate is mounted on the first housing, and then the first metal sheet is placed on the side of the first transmission plate that backs the first housing. Next, the second metal sheet is placed on the surface of the first metal sheet that backs the first transmission plate. Next, the second transmission plate is placed on the surface of the second metal sheet that backs the first metal sheet. Finally, the second housing is mounted on the first housing.

[0135] In another scenario of another embodiment, the step of providing a metal housing includes forming a first housing and a second housing, providing a metal sheet, attaching the metal sheet to a first transmission plate, attaching the first transmission plate to which the metal sheet is attached by facing the first transmission plate, attaching a second transmission plate to the side of the metal sheet that backs the first transmission plate, and then attaching the second housing over the first housing such that the transmission parts of the first transmission plate are positioned within a shielding cavity formed by the first housing and the metal sheet and the transmission parts of the second transmission plate are positioned within a shielding cavity formed by the second housing and the metal sheet.

[0136] In yet another scenario of another embodiment, providing the metal housing includes forming a first housing and a second housing, arranging a transmission component or transmission plate on the first housing, and buckling the second housing to the first housing such that the transmission component is mounted in a shielding cavity formed by the first housing and the second housing, the first electrical connection is electrically connected to the first housing, and the second electrical connection is electrically connected to the second housing. It will be understood that one transmission component corresponds to one independent shielding cavity, and a certain amount of transmission components is the same as a certain amount of shielding cavities.

[0137] In the present application, the transmission component 50 is first formed, and then the transmission component 50 is mounted in the shield cavity of the metal housing 10, in which the at least two electrical connections are respectively electrically connected to the portion of the metal housing 10 that the at least two electrical connections face. That is, the at least two electrical connections on the shield layer 2a that face different directions are respectively electrically connected to the peripheral wall of the shield cavity that the at least two electrical connections face. Thus, when the signal returns from the peripheral wall of the shield cavity to the wire 2, the signal on the peripheral wall of the shield cavity is transmitted to the electrical connection on the shield layer 2a that is close to the peripheral wall. Compared with the case where the peripheral wall of the shield cavity is electrically connected to only one electrical connection on the shield layer 2a, the signal return path is shorter and the loop inductance is smaller, thereby effectively reducing the crosstalk effect of the connector assembly 100 and supporting signal transmission at rates of 112 Gbps and higher.

[0138] The above description is merely some embodiments and implementations of the present application, and is not intended to limit the scope of protection of the present application. Any modifications or replacements that can be easily understood by those skilled in the art within the technical scope disclosed in the present application will fall into the scope of protection of the present application. Therefore, the scope of protection of the present application shall be subject to the scope of protection of the claims.
