[0002] With the development of communication technologies, the communication capacity of communication devices has been continuously increasing. The transmission rate of a single link has been upgraded from 56G to 224G, and the resulting signal crosstalk has also increased.

[0052] 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 the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of the present application.

[0053] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and 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 should not be construed as a limitation to the present application.

[0054] The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating 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 specified, the meaning of "a plurality" is two or more.

[0055] In the description of the present application, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" 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 components. 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 circumstances.

[0056] The present application provides a cable connector and 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 the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0057] Reference Figure 1 and Figure 2 The cable connector provided by the present application includes a conductive housing 1, a signal transmission module 2, a cable 3, a ground plate 4, and a plastic sealing housing 5. Among them, the signal transmission module 2 is received and fixed in the conductive housing 1. Each signal transmission module 2 includes a plurality of signal terminal pairs 21, a support member 22, a conductive member 23, and a shielding member 24. The plurality of signal terminal pairs 21 are arranged in a row and are fixedly supported by plastic encapsulation through the support member 22. The conductive member 23 is disposed on the outer peripheral side of the signal terminal pair 21. The shielding member 24 is connected to the plurality of conductive members 23 and forms a plurality of grounding channels 20. Each grounding channel 20 is at least partially in contact with the conductive housing 1 for grounding and surrounds the corresponding signal terminal pair 21. It can be understood that the grounding channel 20 is annular, and the annular grounding channel 20 does not mean that the grounding channel 20 is circular, but means that the trajectory of the grounding channel 20 in its cross-section is continuous and unbroken. Among them, the cable 3 can be a high-speed cable.

[0058] Compared with the prior art, in the cable connector of the present application, the conductive member 23 and the shielding member 24 are connected and then contact the conductive housing 1 to form a grounding channel 20. That is, after the conductive member 23 and the shielding member 24 are connected, a plurality of annular grounding channels 20 can be formed. Each grounding channel 20 completely surrounds the corresponding signal terminal pair 21 from all around. That is to say, each pair of signal terminal pairs 21 is surrounded by the corresponding grounding channel 20 from all around. The annular grounding channel 20 can enhance the shielding performance and prevent electromagnetic crosstalk between the signal terminal pair 21 and the adjacent signal terminal pairs 21 in its signal path, thereby increasing the shielding performance of the cable connector and reducing the problems of low signal transmission rate and slow signal transmission speed caused by crosstalk problems.

[0059] Refer to Figure 3and Figure 4 The cable connector further includes a cable 3. The conductive housing 1 has opposite docking surfaces 11 and connection surfaces 12, and both the docking surface 11 and the connection surface 12 are parallel to the horizontal plane. Moreover, an installation through groove 13 is provided on the conductive housing 1, and the installation through groove 13 has an extending direction Z, and the extending direction Z is inclined with respect to the horizontal plane. The cable 3 has an inclined section 31, a bent section 32, and a lead section 33 connected in sequence. The lead section 33 is parallel to the horizontal plane. The signal terminal pair 21 is inclined and arranged in the conductive housing 1. One end of the inclined section 31 away from the bent section 32 extends into the installation through groove 13 and is electrically connected to the signal terminal pair 21. One end of the inclined section 31 close to the bent section 32 extends out of the conductive housing 1 from the installation through groove 13, so that the height of the cable connector in this application can be reduced, which is beneficial to realizing the structural compactness of the cable connector.

[0060] Based on the above embodiment, at least a part of the inclined section 31 close to the signal terminal pair 21 is located in the grounding channel 20, that is, at least a part of the cable 3 extends into the grounding channel 20 formed by the conductive member 23 and the shielding member 24. Or, the inclined section 31 has a connecting portion close to the signal terminal pair 21, and the connecting portion extends into the grounding channel, so as to ensure that the signal terminal pair 21 is completely surrounded by the grounding channel 20 in its signal path, thereby realizing a complete shielding and grounding effect of the signal terminal pair 21 in its signal path.

[0061] Wherein, the inclined angles of the installation through groove 13, the inclined section 31 and the signal terminal pair 21 are the same, and the inclination angle α between the installation through groove 13, the inclined section 31 and the signal terminal pair 21 and the horizontal plane satisfies: α ≤ 45°. Thus, not only can the height of the cable connector be ensured to be appropriate, but also the risk of contact deformation of the mating contact 211 where the signal terminal pair 21 extends out of the conductive housing 1 can be prevented.

[0062] It can be understood that the above signal terminal pairs 21 can be combined into different combinations according to actual needs. For example, in the conductive housing 1 of the cable connector of the present application, 4 sets of signal transmission modules 2 are provided, and each set of signal transmission modules 2 includes 8 signal terminal pairs 21. Of course, 2 sets of signal transmission modules 2 can also be provided in the conductive housing 1 of the cable connector, and each set of signal transmission modules 2 includes 8 signal terminal pairs 21. Or, 6 sets of signal transmission modules 2 can also be provided in the conductive housing 1 of the cable connector, and each set of signal transmission modules 2 includes 8 signal terminal pairs 21. Or, 4 sets of signal transmission modules 2 can also be provided in the conductive housing 1 of the cable connector, and each set of signal transmission modules 2 includes 4 signal terminal pairs 21. Or, 4 sets of signal transmission modules 2 can also be provided in the conductive housing 1 of the cable connector, and each set of signal transmission modules 2 includes 12 signal terminal pairs 21. The present application does not specifically limit the number of sets of signal transmission modules 2 and the number of signal terminal pairs 21.

[0063] In some embodiments of the present application, referring to Figures 4 to 7 , both ends of the installation through groove 13 penetrate through the docking surface 11 and the connection surface 12 of the conductive housing 1 respectively. The signal terminal pair 21 has a butt contact head 211 facing away from the cable 3, and the butt contact head 211 extends out of the installation through groove 13 at the port of the docking surface 11. And the signal terminal pair 21 has a wiring contact head 212 connected to the cable 3, and the wiring contact head 212 and the butt contact head 211 are arranged opposite to each other. The cable connector further includes a grounding plate 4, the grounding plate 4 is arranged on the docking surface 11, the grounding plate 4 is provided with a grounding enclosure portion 41 and grounding elastic pieces 42 arranged around the outer periphery of the grounding enclosure portion 41. The grounding enclosure portion 41 surrounds the butt contact head 211, and the grounding elastic pieces 42 protrude in a direction away from the docking surface 11. The above grounding elastic pieces 42 are used to communicate with the grounding line in the circuit board. The grounding enclosure portion 41 surrounds the butt contact head 211 to perform complete shielding grounding around the butt contact head 211 of the signal terminal pair 21, thereby reducing crosstalk between the butt contact head 211 in this signal terminal pair 21 and the butt contact head 211 in the adjacent signal terminal pair 21.

[0064] Exemplarily, the above grounding enclosure portion 41 is a square through hole provided on the grounding plate 4, that is, the grounding enclosure portion 41 surrounds the outer periphery of the butt contact head 211 and is uninterrupted. There are eight upper grounding elastic pieces 42, and they are grouped in pairs and respectively arranged on the four side edges of the square through hole. It can also be understood that an equal number of grounding elastic pieces 42 are arranged around each side edge of the above square through hole. For example, 3 or 4 or other more numbers of grounding elastic pieces 42 can also be arranged around each side edge of the above square through hole. Among them, the more the number of grounding elastic pieces 42, the more beneficial it is to improve the anti-crosstalk effect of the butt contact head 211 in the signal terminal pair 21.

[0065] It is understandable that the inclined section 31 is welded to the signal terminal pair 21. To ensure the stability and reliability of the cable 3 and the corresponding signal terminal pair 21 at the connection, the above signal transmission module 2 further includes a protection member 25, as Figure 8 shown. The protection member 25 is wrapped around the outer periphery of the welding position of the cable 3 and the signal terminal pair 21. Among them, the above protection member 25 can be made by a plastic encapsulation process or a dispensing process.

[0066] Referring to Figure 3 、 Figure 4 and Figure 7 , the protection member 25 is made by a plastic encapsulation process, that is, the protection member 25 is a plastic encapsulated part, and it fixes the welding position through the plastic encapsulation process, so that the signal terminal pair 21, the support member 22, the conductive member 23, the shielding member 24 and the cable 3 are fixedly connected and form an integral structure, so that the above-mentioned components form a modular part, which is convenient to be installed into the installation through groove 13 of the conductive housing 1. At the same time, the plastic encapsulation fixing frame made by the injection molding process has a simple manufacturing process and high manufacturing efficiency.

[0067] Referring to Figure 3 and Figure 8 , an installation through groove 13 is formed in the conductive housing 1. An engaging portion 251 is provided on the outer periphery of the protection member 25, and a fitting portion 131 is provided on the inner wall of the installation through groove 13. The engaging portion 251 and the fitting portion 131 are matched with each other and both extend along the extending direction Z of the installation through groove 13. Through the mutually cooperating engaging portion 251 and fitting portion 131, the guiding and positioning can be realized when the modular signal transmission module 2 is installed into the conductive housing 1. Exemplarily, the above engaging portion 251 is an engaging groove, and the engaging groove is provided on the outer periphery of the protection member 25 and recesses toward the inside of the protection member 25. The above fitting portion 131 is a fitting post formed on the inner wall of the installation through groove 13 and protruding toward the inside of the installation through groove 13. The extending directions of the above engaging groove, fitting post, installation through groove 13 and the signal terminal pair 21 are the same. That is, the above installation through groove 13 is inclined with respect to the docking surface 11, so as to realize the inclined installation of the modular signal transmission module 2. Specifically, the above protection member 25 has a strip-shaped structure, and its length direction is consistent with the arrangement direction of the signal terminal pair 21.

[0068] Exemplarily, the above-mentioned fitting groove is strip-shaped and generally U-shaped. Its open end faces the mating contacts 211 of the signal terminal pair 2, and its closed end is away from the mating contacts 211 of the signal terminal pair 2. Thereby, the installation depth of the signal transmission module 2 installed on the conductive housing 1 is restricted, realizing the insertion depth of the two in the installation direction. Furthermore, the length of the mating contacts 211 of the signal terminal pair 2 protruding from the conductive housing 1 can be controlled, ensuring the reliability of the electrical connection between the mating contacts 211 and the signal conductive sheet docked with them. Specifically, when the modular signal transmission module 2 is installed on the conductive housing 1 from the top of the conductive housing 1, the closed end of the U-shaped fitting groove will abut against the fitting post, causing the signal transmission module 2 to be unable to continue to be inserted downward.

[0069] Refer to Figure 2 、 Figure 9 and Figure 10 , the shielding member 24 is generally plate-shaped. The conductive member 23 includes a plurality of U-shaped parts, each of which includes a fixing portion 231 close to the cable 3. The shielding member 24 includes a clamping plate portion 241 arranged opposite to the fixing portion 231. The end side of the cable 3 close to the signal terminal pair 21 is fixed between the fixing portion 231 and the clamping plate portion 241, ensuring relatively high welding stability and reliability at the welding position of the cable 3 and the connection contacts 212 of the signal terminal pair 21. Among them, the above-mentioned clamping plate portion 241 is arranged in imitation of the outer circumference of the cable 3, that is, the clamping plate portion 241 is a generally U-shaped clamping groove. The cable 3 is placed in the clamping groove, and part of its wall surface is attached to the inner wall of the clamping groove. The fixing portion 231 is a fixing groove, which is arranged outside the other part of the wall surface of the cable 3 to fix and clamp the cable 3 on the clamping plate portion 241.

[0070] Of course, in some other embodiments of the present application, in order to reduce the number of components in the signal transmission module 2, the above-mentioned plurality of conductive members 23 can also be of an integral structure, as long as a connecting portion is provided between the plurality of conductive members 23. The purpose of setting the conductive member 23 in multiple is to be able to freely combine the number of signal terminal pairs 21. At this time, just select the appropriate number of conductive members 23 as needed.

[0071] In order to achieve the positioning and fixation among the conductive member 23, the shielding member 24 and the support member 22, the conductive member 23 includes a main body portion 232 away from the cable 3. The shielding member 24 includes a shielding main board 242 disposed opposite to the main body portion 232. The shielding main board 242 is provided with a first set of riveting holes 2421, the main body portion 232 is provided with a second set of riveting holes 2321, and the support member 22 is provided with two sets of riveting posts 221. One set of the two sets of riveting posts 221 protrudes towards the shielding main board 242 and is riveted to the first set of riveting holes 2421, and the other set of riveting posts 221 protrudes forward and is riveted to the second set of riveting holes 2321. The extending directions of the two sets of riveting posts 221 are opposite, and the connection method of this riveting connection is relatively simple. Alternatively, the conductive member 23, the shielding member 24 and the support member 22 can be fixedly connected by means of snap connection, threaded connection or welding, etc.

[0072] The above-mentioned conductive member 23 is sequentially connected and formed by a fixing portion 231, an intermediate connecting portion 233 and a main body portion 232. The above-mentioned shielding member 24 is sequentially connected and formed by a clamping plate portion 241, a bending portion 243 and a shielding main board 242. Moreover, the above-mentioned conductive member 23 and the above-mentioned shielding member 24 are both of integral structure. Among them, the main body portion 232 and the shielding main board 242 are arranged away from the wiring contact 212 of the signal terminal pair 21. The intermediate connecting portion 233 and the bending portion 243 are arranged relative to the welding positions of the signal terminal pair 21 and the cable 3, and both the intermediate connecting portion 233 and the bending portion 243 are provided with hollow areas. The fixing portion 231 and the clamping plate portion 241 are used to fix and clamp the above-mentioned cable 3. The above-mentioned hollow areas can ensure that the encapsulation material of the encapsulation fixing member 25 completely wraps the welding positions of the signal terminal pair 21 and the cable 3.

[0073] Continue to refer to Figure 3 and Figure 10 , an installation through groove 13 is provided in the conductive housing 1. The conductive member 23 includes a first side wall 234 and a second side wall 235 disposed on both sides of the corresponding signal terminal pair 21, and an intermediate side wall 236 connecting the first side wall 234 and the second side wall 235. A contact portion 2361 is provided on the intermediate side wall 236. The contact portion 2361 contacts the inner wall of the installation through groove 13 to achieve elastic contact with the conductive housing 1, so as to realize the grounding series connection of the entire link by using the conductive housing 1, and ensure the reliability of the product by using the overall stable performance of the conductive housing 1. Similarly, the shielding member 24 is also provided with contact contacts on the side wall opposite to the support member 22, and the contact contacts are elastically in contact with the inner wall of the installation through groove 13.

[0074] Among them, first positioning portions are provided on the first side wall 234 and the second side wall 235 of the conductive member 23, and second positioning portions are provided on the shielding main board 242 of the shielding member 24. When the conductive member 23 and the shielding member 24 are both connected to the support member 22, the first positioning portion and the second positioning portion are adapted to each other, thereby defining the relative positions between the conductive member 23 and the shielding member 24. For example, the first positioning portion is a first positioning block, the second positioning portion is a second positioning hole, and the first positioning block and the second positioning hole are adapted to each other. Or, the first positioning portion is a positioning buckle, the second positioning portion is a positioning card hole, and the positioning buckle and the positioning card hole are snap-connected.

[0075] In order to achieve the shielding grounding of the entire row of signal transmission modules 2 and improve the anti-crosstalk effect of the entire row of signal transmission modules 2, a first conductive portion 2341 is provided on the first side wall 234, and a second conductive portion 2351 (see the label in Figure 2 ) is provided on the second side wall 235. The first conductive portion 2341 and the second conductive portion 2351 are in elastic contact. One of the first conductive portion 2341 and the second conductive portion 2351 is a connecting protrusion, and the other is a connecting elastic piece. Or, both the first conductive portion 2341 and the second conductive portion 2351 are connecting protrusions, or both the first conductive portion 2341 and the second conductive portion 2351 are connecting elastic pieces. In this application, by making one of the first conductive portion 2341 and the second conductive portion 2351 a connecting protrusion and the other a connecting elastic piece, it is ensured that the two are in elastic contact, so as to increase the error tolerance rate during the installation process of the above components and reduce the manufacturing precision requirements of each component, thereby ensuring the stable and reliable electrical connection between the first conductive portion 2341 and the second conductive portion 2351.

[0076] It should be noted that the first conductive portion 2341 on one of the two conductive members 23 located at the end side and the second conductive portion 2351 on the other conductive member 23 are both in elastic contact with the installation through groove 13 of the conductive housing 1 to further realize the grounding series connection of the entire link. As Figure 11 shown, the first conductive portion 2341 (shown as a connecting protrusion as Figure 11 shown) on the conductive member 23 located on the left side and the second conductive portion 2351 (shown as a connecting elastic piece as Figure 11 shown) on the other conductive member 23 are both in contact with the inner wall of the installation through groove 13 of the conductive housing 1.

[0077] Continuing to refer to Figure 1 , the cable connector further includes a plastic sealing housing 5. The plastic sealing housing 5 plastic-seals and fixes the conductive housing 1 and a plurality of signal transmission modules 2 provided in the conductive housing 1 to form a modular cable connector.

[0078] Thus, the grounding path of the cable connector provided by this application is composed of a conductive member 23, a shielding member 24, a conductive housing 1, a grounding plate 4, and a grounding spring piece 42 thereon. Connecting spring pieces and connecting protrusions are arranged on the left and right sides of the conductive member 23 and are in shielding contact with the conductive member 23. After the conductive member 23 is connected to the shielding member 24, all the signal terminal pairs 21 are surrounded to form a signal transmission module. Different numbers of signal transmission modules are combined according to application requirements through the conductive housing 1. An elastic contact portion 2361 is further arranged at the bottom of the conductive member 23 and is in elastic contact with the inner wall of the installation through groove 13 of the conductive housing 1. A grounding plate 4 is arranged at the bottom of the conductive housing 1. The mating contact heads 211 of the signal terminal pairs 2 are located within the grounding frame portion 41 of the grounding plate 4. Grounding spring pieces 42 are arranged around the grounding frame portion 41 for grounding contact with the PCB, thereby forming the grounding connection of the entire connector. Through the above structure, the shielding performance of the cable connector can be improved, and the problems of low signal transmission rate and slow signal transmission speed caused by crosstalk problems can be reduced.

[0079] Specifically, as Figure 12 shown, the figure shows the low-crosstalk simulation data of the above cable connector of this application. Among them, in the range of frequencies from 0 GHz to 80 GHz, the crosstalk specification of this cable connector is below -50 dB. Therefore, the cable connector with the above structure has good shielding performance.

[0080] In the description of this specification, specific features, structures, materials, or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0081] The above is only the specific implementation manner of this application, but the protection scope of this application is not limited thereto. Any person skilled in the art within the technical scope disclosed by this application can easily think of changes or substitutions, which should all be covered within the protection scope of this application. Therefore, the protection scope of this application should be subject to the protection scope of the claims. In addition, specific examples are used in the specification to elaborate on the principle and implementation manner of this application. The description of the above embodiments is only used to help understand the method and its core idea of this application. The content of this specification should not be construed as a limitation to this application.
