[0088] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0089] In the description of the present application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application.

[0090] The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise stated, the meaning of "a plurality" is two or more.

[0091] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0092] The present application provides a connector assembly, which will be described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present application. And in the following embodiments, each embodiment has its own emphasis. For parts not described in detail in a certain embodiment, reference may be made to the relevant descriptions of other embodiments.

[0093] Figure 1 is an exploded view of the connector assembly in an embodiment of the present application. Referring to Figure 1 it can be seen that the connector assembly includes a board - end connector 1 and a wire - end connector 10. Among them, the board - end connector 1 is used to connect to a circuit board 30, and the wire - end connector 10 is used to connect to a cable 40, thereby realizing the board - to - wire docking through the above - mentioned connector assembly.

[0094] Next, the structure of the board - end connector 1 in the connector assembly of the present application will be introduced in detail.

[0095] Figure 2 is an exploded view of the board - end terminal module in an embodiment of the present application. Figure 3 is a schematic structural diagram of a signal terminal pair and a ground terminal in an embodiment of the present application. Referring to Figures 1 to 3 , the above - mentioned board - end connector 1 includes an insulating housing 2 and a board - end terminal module 3 disposed in the insulating housing 2. The board - end terminal module 3 includes an insulating bracket 31, a plurality of signal terminal pairs 4, and a plurality of ground terminals 5. Among them, the insulating bracket 31 is generally plate - shaped and has opposite top edges 311 and bottom edges 312. The plurality of signal terminal pairs 4 are all supported by the insulating bracket 31, and each signal terminal pair 4 has a mounting contact 41 extending out of the top edge 311 and a mating contact 42 close to the bottom edge 312. The plurality of ground terminals 5 are all supported by the insulating bracket 31, and at least one signal terminal pair 4 is provided between two adjacent ground terminals 5. Each ground terminal 5 has a ground tail 51 extending out of the top edge 311 and a ground front 52 close to the bottom edge 312, and the two adjacent ground fronts 52 are connected and surround the corresponding signal terminal pair 4.

[0096] Compared with the prior art, in the present application, the ground fronts 52 of two adjacent ground terminals 5 are connected and surround the corresponding signal terminal pair 4, ensuring that the signal terminal pair 4 is completely surrounded by the ground terminals 5 in its signal path. Thus, through the above - mentioned ground terminals 5, a complete shielding and grounding effect of the signal terminal pair 4 in its signal path is achieved, effectively preventing electromagnetic crosstalk between the signal terminal pair 4 and adjacent signal terminal pairs 4 in its signal path.

[0097] Among them, the ground fronts 52 of the two adjacent connected ground terminals 5 are connected. More specifically, as Figure 3As shown, the two connected grounding terminals 5 described above can be of an integral structure. Of course, the two connected grounding terminals 5 can also be of a split structure, as long as it is ensured that the grounding front ends 52 of the two grounding terminals 5 can conduct electricity and surround the mating contact heads 42.

[0098] Please continue to refer to Figure 2 and Figure 3 As shown, the insulating bracket 31 has a first side surface 313 and a second side surface 314 that are opposite and vertically arranged. The board-end terminal module 3 further includes a grounding board 6. The grounding board 6 includes a grounding main board portion 61 and a contact portion 62. The grounding main board portion 61 is connected to the first side surface 313, and the contact portion 62 is electrically connected to the grounding terminal 5, so as to ground and shield the side of the signal terminal pair 4 facing the first side surface 313. Thus, the shielding effect on the signal terminal pair 4 is further improved through the grounding board 6, preventing electromagnetic interference from occurring.

[0099] It should be noted that the mating contact heads 42 of the plurality of signal terminal pairs 4 close to the bottom edge 312 and the grounding front ends 52 of the plurality of grounding terminals 5 close to the bottom edge 312 do not extend beyond the bottom edge of the insulating bracket 31, but are encapsulated inside the insulating bracket 31, ensuring that the plurality of signal terminal pairs 4 and the plurality of grounding terminals 5 have good ortho-position on the insulating bracket 31, that is, they will not deflect.

[0100] Furthermore, the grounding terminal 5 further includes a main body portion 53 connecting the grounding front end 52 and the grounding tail end 51. The grounding main board portion 61 has a top edge 611 and a bottom edge 612 that are oppositely arranged, and the contact portions 62 are provided on both the top edge 611 and the bottom edge 612. The contact portion 62 is configured as a conductive elastic piece bent toward the second side surface 314, and the conductive elastic piece contacts the main body portion 53, thereby realizing the installation and fixation of the grounding board 6 and its electrical connection with the grounding terminal 5.

[0101] Among them, it can be understood that a hollow portion is provided on the insulating bracket 31, and this hollow portion is used to expose at least a part of the main body portion 53 of the grounding terminal 5 to the outside of the insulating bracket 31, facilitating the contact conduction between the conductive elastic piece and the main body portion 53, that is, realizing the electrical connection between the two.

[0102] Based on the above embodiments, a riveting through-hole 613 is formed on the grounding main board portion 61, and a riveting protrusion 33 protruding in a direction away from the second side surface 314 is formed on the first side surface 313. The riveting protrusion 33 is riveted and assembled with the riveting through-hole 613. Thus, the grounding main board portion 61 is first buckled on the riveting protrusion 33 through the riveting through-hole 613 to achieve pre-positioning between the two, and then fixed by riveting, so as to ensure that the connection manner between the grounding main board portion 61 and the first side surface 313 is relatively simple and easy to implement. At the same time, it can also ensure that the connection between the two is relatively stable and reliable.

[0103] Alternatively, in some embodiments of the present application, the grounding main board portion 61 and the first side surface 313 may also be connected by means of threaded connection, snap connection or bonding through an adhesive layer.

[0104] Exemplarily, there are multiple riveting through-holes 613 on the grounding main board portion 61. Correspondingly, the number of the riveting protrusions 33 is also multiple, and the numbers of both are equal. One grounding main board portion 61 in the present application is riveted and assembled with multiple riveting protrusions 33 through multiple riveting through-holes 613 to ensure the connection reliability of the grounding main board portion 61.

[0105] Figure 4 is a schematic structural diagram of the board-end connector in the embodiment of the present application, showing the bottom structure of the insulating housing in the board-end connector. Figure 5 is a schematic structural diagram of the insulating housing in the embodiment of the present application, showing the top structure of the insulating housing. Figure 6 is a schematic structural diagram of the connector assembly in the embodiment of the present application.

[0106] Combined with Figure 1 、 Figures 4 to 6 it can be seen that the above insulating housing 2 is generally in a box-shaped structure, which has a top plate 21 and an opening facing the bottom to form an insertion port 22. An installation port 211 and an installation block 23 extending towards the insertion port 22 are formed on the top plate 21. The board-end connector 1 further includes a guiding structure 7. The guiding structure 7 includes a guiding protrusion 71 (the label is shown in Figure 2 ) and a vertically arranged guiding groove 72. One of the guiding protrusion 71 and the guiding groove 72 is arranged on the first side surface 313, and the other is arranged on the installation block 23. The installation port 211 is adapted to the outer contour of the top edge 311 to expose the top edge 311 outside the insulating housing 2. Thus, when the above board-end terminal module 3 is inserted into the insulating housing 2 from the installation port 211, the guiding structure 7 can play a guiding role for the two, ensuring that the board-end terminal module 3 can be smoothly inserted into the insulating housing 2, that is, no jamming occurs during the insertion process.

[0107] More specifically, since each of the signal terminal pairs 4 has a mounting contact 41 protruding from the top edge 311, and each of the ground terminals 5 has a ground tail 51 protruding from the top edge 311, the mounting opening 211 is adapted to the outer contour of the top edge 311 to expose the top edge 311 outside the insulating housing 2, that is, to expose the mounting contacts 41 in each of the signal terminal pairs 4 and the ground tails 51 in each of the ground terminals 5 outside the insulating housing 2 to achieve their connection to the circuit board 30.

[0108] It can be understood that the positions of the above-mentioned guiding protrusion 71 and guiding groove 72 can be interchanged. Only the embodiment in which the guiding protrusion 71 is provided on the first side 313 and the guiding groove 72 is provided on the mounting block 23 is shown in the drawings of the present application. At the same time, since the board-end terminal module 3 is inserted into the insulating housing 2 from the mounting opening 211, that is, when the board-end terminal module 3 is inserted into the insulating housing 2 from the top, the bottom of the board-end terminal module 3 first contacts the insulating housing 2. Therefore, the guiding protrusion 71 is provided in the bottom area of the first side 313 to ensure that the guiding protrusion 71 can always play a guiding role during the assembly of the board-end terminal module 3.

[0109] In some embodiments of the present application, the guiding protrusion 71 is configured as a T-shaped protrusion, and the guiding groove 72 is configured as a T-shaped groove. Through the sliding fit between the T-shaped protrusion and the T-shaped groove, it can play a guiding role when the board-end terminal module 3 and the insulating housing 2 are assembled, and can also realize the limiting function of the board-end terminal module 3 and the insulating housing 2 in the width direction of the insulating housing 2, that is, play an appropriate connection role, and further can increase the holding force and structural stability between the board-end terminal module 3 and the insulating housing 2.

[0110] Figure 7 is a schematic diagram of the assembly structure of the board-end terminal module in the embodiment of the present application. Refer to Figure 5 and Figure 7 The board-end connector 1 further includes a clamping structure 8. The clamping structure 8 includes a buckle 81 and a hook 82 that are clamped and connected. One of the buckle 81 and the hook 82 is provided on the second side 314, and the other is provided on the inner wall surface of the mounting opening 211 that cooperates with the second side 314. When the board-end terminal module 3 is installed into the insulating housing 2 and is installed in place, the above-mentioned buckle 81 and hook 82 are clamped and matched to realize the fixation of the board-end terminal module 3 and the insulating housing 2 in the vertical direction. At the same time, the clamping connection does not require an external tool to complete the connection between the two compared with the threaded connection, ensuring that the fixing method between the two is relatively simple and easy to implement.

[0111] It can be understood that the positions of the above-mentioned buckle 81 and hook 82 can be interchanged. Only the embodiment in which the buckle 81 is provided on the second side surface 314 and the hook 82 is provided on the inner wall surface where the mounting opening 211 cooperates with the second side surface 314 is shown in the accompanying drawings of the present application. Among them, the above-mentioned buckle 81 is provided in the top area of the second side surface 314. It should be explained that a deformation space is provided on the side of the above-mentioned hook 82 facing away from the buckle 81. This deformation space can be formed by opening a groove recessed toward the top surface on the bottom surface of the top plate 21 of the insulating housing 2. Thus, when the buckle 81 is pressed into the insulating housing 2, the hook 82 will deform toward the side away from the buckle 81 to avoid the buckle 81 so that the buckle 81 can be pressed into the insulating housing 2 and be engaged with the hook 82.

[0112] Exemplarily, the above-mentioned insulating housing 2 is generally in a box-shaped structure in the shape of a cuboid, and the mounting block 23 is also generally in a long strip shape, which has two long side walls and two short side walls. Three buckles 81 are provided on the second side surface 314 of the insulating bracket 31, and three hooks 82 are also provided on the inner wall surface of the mounting opening 211 that cooperates with the second side surface 314. In addition, four substantially rectangular mounting openings 211 are opened on the top plate 21 of the insulating housing 2. Correspondingly, the above-mentioned board-end terminal module 3 also includes four. Two of the four board-end terminal modules 3 are arranged in a row and are provided on one of the two long side walls of the mounting block 23, and the other two of the four board-end terminal modules 3 are arranged in a row and are provided on the other of the two long side walls of the mounting block 23.

[0113] Furthermore, the grounding plate 6 in the two rows of face-to-face arranged board-end terminal modules 3 can also shield the two signal terminal pairs 4 that are face-to-face arranged in the two board-end terminal modules 3, preventing crosstalk between the signal terminal pairs 4 in the two rows of face-to-face arranged board-end terminal modules 3.

[0114] It should be noted that the two board-end terminal modules 3 in the same row can also be of an integral structure. Correspondingly, the two mounting openings 211 in the same row can also be connected to form a relatively large mounting opening 211. Among them, the mounting opening 211 is connected to the mounting block 23, that is, in the horizontal projection plane, the long side wall of the above-mentioned mounting block 23 and the inner side wall of the mounting opening 211 close to the mounting block 23 are the same side wall.

[0115] Continue to refer to Figure 1 and Figure 4, the outer edge of the above-mentioned insertion interface 22 is configured as a hanging edge, and the board-end connector 1 further includes a shielding plate 9 provided outside the insulating housing 2. The shielding plate 9 includes a shielding substrate 91, a hanging portion 92, and a grounding pin 93. The shielding plate 9 has a top shielding edge 911 and a bottom shielding edge 912 that are oppositely arranged. The hanging portion 92 is provided on the bottom shielding edge 912, and a receiving portion 24 corresponding to the hanging portion 92 is provided on the hanging edge. The grounding pin 93 is provided on the top shielding edge 911 and extends upward to the outside of the insulating housing 2 for communicating with the grounding line in the circuit board 30, thereby realizing the shielding grounding of the entire board-end connector 1 and ensuring better crosstalk prevention effect of the above-mentioned board-end connector 1.

[0116] Exemplarily, the above-mentioned shielding plate 9 has four pieces and are all embedded in the outer periphery of the insulating housing 2, forming a complete plane with the outer wall surface of the insulating housing 2, ensuring that the above structure is more beautiful. Of course, the above four shielding plates 9 can also be made into an integral structure and sleeved on the outer periphery of the insulating housing 2. The above-mentioned grounding pin 93 is generally in the shape of a fish eye and extends vertically upward in a plane parallel to the shielding substrate 91.

[0117] It should be noted that the grounding lines in the above-mentioned circuit board 30 are all short-circuited designs, so as to ensure that the return path of the grounding line is shorter, so as to further increase the electromagnetic interference resistance of the board-end connector 1 and reduce crosstalk.

[0118] Based on the above embodiment, the shielding substrate 91 has a shielding inner side 913 covering the insulating housing 2 and a shielding outer side 914 opposite to the shielding inner side 913. The hanging portion 92 is configured as a U-shaped hook that bends toward the shielding inner side 913 and opens toward the top shielding edge 911. The receiving portion 24 is configured as a receiving groove that recesses toward the inside of the insulating housing 2. The U-shaped hook is embedded in the receiving groove to realize the limit of the shielding plate 9 and the insulating housing 2 in the length direction of the insulating housing 2.

[0119] Figure 8 is a cross-sectional view of the board-end connector in the embodiment of the present application to show the connection structure of the anti-retreat elastic piece and the anti-retreat groove. Further, refer to Figure 4 and Figure 8, in order to fix the shielding plate 9 and the insulating housing 2 in the vertical direction, a backstop spring piece 94 is provided on the shielding substrate 91 described above. The backstop spring piece 94 is bent toward the shielding inner side 913, and a backstop groove 25 matching the backstop spring piece 94 is provided on the insulating housing 2. Thus, when the shielding plate 9 is hung from the bottom to the insulating housing 2, the backstop spring piece 94 and the backstop groove 25 are snapped together to realize the vertical fixation of the shielding plate 9 and the insulating housing 2. At the same time, the manufacturing processes of the backstop spring piece 94 and the backstop groove 25 are relatively simple and easy to implement.

A grounding spring piece 95 bent toward the shielding outer side 914 is provided on the shielding substrate 91. When the wire-end connector 10 and the board-end connector 1 are assembled, the grounding spring piece 95 contacts the inner side wall of the conductive housing 11. Thus, through the shielding plate 9, not only the shielding grounding of the board-end connector 1 is realized, but also the shielding grounding of the wire-end connector 10 can be realized, thereby realizing the shielding grounding of the entire connector assembly and ensuring better anti-crosstalk effect of the connector assembly.

The connector assembly further includes a metal mounting seat 12 and a conductive plate 15. The metal mounting seat 12 is used to mount the conductive housing 11. The conductive plate 15 is used to electrically connect the metal mounting seat 12 and the conductive housing 11. Thus, when the connector assembly is mounted to other components through the metal mounting seat 12 above, the metal mounting seat 12 can also play a role in shielding grounding.

[0122] More specifically, as Figure 1 shown, the conductive housing 11 includes a top shell 111 and a bottom shell 112. The top shell 111 is docked with the insulating housing 2, and the bottom shell 112 is connected to the metal mounting seat 12.

Thus, the adjustment distance of the conductive housing 11 relative to the metal mounting base 12 in the vertical direction can be controlled by controlling the depth of the screw 161 screwed into the threaded hole 163, that is, the above gasket 162 is not completely pressed between the conductive housing 11 and the metal mounting base 12.

[0127] More specifically, arc-shaped grooves are provided on both side walls of the conductive housing 11 parallel to the width direction. Correspondingly, arc-shaped protrusions corresponding to the arc-shaped grooves are provided on the metal mounting base 12, facilitating the gasket 162 to cover both the conductive housing 11 and the metal mounting base 12 at the same time. It can be understood that in order to facilitate the cable 40 to pass through the metal mounting base 12, a wire passing port is further provided on one side wall of the metal mounting base 12.

After the cable 40 is welded to the cable connection portion 183, the connection between the cable connection portion 183 and the cable 40 is then sealed on the conductive housing 11 through a plastic sealing bottom plate 20 (reference number see Figure 11 ).
