Description

Technical Field

[0001] This application relates to the field of connector technology, and in particular to a cable connector assembly. Background Technology

[0002] In modern electronic equipment signal transmission, cable connector assemblies are crucial for signal stability. Differential signal transmission technology is widely used in various fields due to its strong anti-interference capabilities and high efficiency. In connector products that adapt to twisted-pair cables, to ensure electrical performance and that the spacing between the two cores of the twisted pair matches the spacing between the two center conductors of the connector, the two cores of the twisted pair need to be separated and shaped. This allows the core spacing to smoothly transition from the cable's own adaptation size to the connector's adaptation size. However, in related technologies, the separation and shaping process is complex, which not only reduces product manufacturing efficiency but also leads to inconsistent product yields due to operational differences after shaping. Utility Model Content

[0003] Based on this, this application provides a cable connector assembly, including:

[0004] The cable includes two core wires arranged side-by-side in a first direction and a shielding layer covering the two core wires, with one end of each core wire exposed outside the shielding layer; and

[0005] The fixing clip is an elastic, one-piece molded part. The fixing clip includes two lobes arranged opposite each other in a second direction perpendicular to the first direction and a connecting part connecting the two lobes into one piece. The lobes have a first side and a second side arranged opposite each other in the first direction. The connecting part is connected to the first side of the two lobes. An opening slit is provided between the second sides of the two lobes. Two guide channels are formed between the two lobes. One guide channel is used to hold one of the core wires, and the other guide channel is used to hold the other core wire.

[0006] Furthermore, the opening has an open state and a closed state, respectively. When the opening is in the open state, the two core wires can be installed in the corresponding guide channels; when the opening is in the closed state, the two core wires are held in the corresponding guide channels.

[0007] Furthermore, the opening is in a closed state under natural conditions, and the fixing clamp can deform under external force to change the opening from the closed state to the open state; the fixing clamp can also deform to restore the opening from the open state to the closed state; and / or,

[0008] The cable connector assembly further includes a first welding structure disposed on a second side of the two said lobe portions, the first welding structure being used to keep the opening slit in the closed state.

[0009] Furthermore, at least one of the two lobes is recessed toward the other lobe to form a recessed structure and construct two guide channels located on both sides of the recessed structure in a first direction.

[0010] Furthermore, the fixing clamp has a first receiving space and a second receiving space arranged sequentially along the axial direction of the cable;

[0011] A portion of the shielding layer is held within the first containment space;

[0012] The second receiving space is divided into two guide channels by the recessed structure, and the two guide channels are respectively connected to the first receiving space.

[0013] Furthermore, the lobe portion includes a first clamping body, a transition body, and a second clamping body sequentially connected as an integral part along the axial direction of the cable. The connecting portion is connected between the second clamping bodies of the two lobe portions. The width of the second clamping body in the first direction is greater than the width of the first clamping body in the first direction. The transition body extends from the second clamping body toward the first clamping body and its two sides in the first direction approach each other to connect with the first clamping body.

[0014] The first clamping body of the two said lobes surrounds the first receiving space, the transition body of the two said lobes and the second clamping body surround the second receiving space, and the transition body and the second clamping body of at least one of the two said lobes are recessed toward the other said lobes to form the recessed structure.

[0015] Furthermore, the core wire includes an inner conductor and an insulating layer covering the inner conductor. One end of the inner conductor protrudes outside the insulating layer. The inner conductor protruding from the insulating layer protrudes outside the fixing clamp and is insulated from the fixing clamp. One end of the insulating layer protrudes outside the shielding layer. At least a portion of the insulating layer protruding outside the shielding layer is clamped between the two segments. A portion of the shielding layer is clamped between the two segments and electrically connected to the fixing clamp.

[0016] Furthermore, the cable connector assembly also includes:

[0017] Two center conductors are crimped one-to-one with the ends of the two core wires exposed in the shielding layer and electrically connected to the corresponding core wires; and

[0018] External conductor composite;

[0019] The center conductor, the fixing clip, and part of the cable are held within the outer conductor composite, and the center conductor is insulated from the outer conductor composite. The fixing clip and the shielding layer are electrically connected to the outer conductor composite.

[0020] Furthermore, the outer conductor composite includes:

[0021] First shielding shell;

[0022] An insulator is pressed into one end of the first shielding shell; and

[0023] The second shielding shell is fixed to the outside of the end of the first shielding shell where the insulator is located to hold the insulator between the first shielding shell and the second shielding shell. The second shielding shell is electrically connected to the first shielding shell.

[0024] The center conductor is inserted into the insulator from the end of the first shielding shell away from the insulator, and is insulated from the first shielding shell and the second shielding shell through the insulator. The fixing clip is fixed inside the first shielding shell and electrically connected to the first shielding shell. The end of the first shielding shell away from the insulator is pressed against the outside of the cable and electrically connected to the shielding layer.

[0025] Furthermore, the second shielding shell has an inwardly protruding bulge that abuts against the first shielding shell; and / or,

[0027] Furthermore, the shielding layer includes an aluminum foil layer covering the core wire and a metal braided layer covering the aluminum foil layer, wherein one end of the aluminum foil layer is exposed outside the metal braided layer, and a portion of the aluminum foil layer is clamped between the two segments and electrically connected to the fixing clamp.

[0028] The cable connector assembly further includes a cable clamp, which is pressed onto the metal braided layer. A portion of the metal braided layer is folded outward to wrap around the cable clamp. The folded metal braided layer is held between the first shielding shell and the cable clamp and is electrically connected to the first shielding shell.

[0029] Furthermore, the first shielding shell includes a flap, which is pressed against the outside of the cable to form a cylindrical structure that holds the folded metal braided layer in place. The cable connector assembly also includes a fourth welding structure, which is used to weld and fix the flap or to weld and fix the flap and the cable.

[0030] Compared with the prior art, the beneficial effects of this application are as follows: The cable connector assembly includes a retaining clip with an open slot, which facilitates the insertion of two core wires between two segments. Two guide channels can respectively hold the two core wires. The guide channels constrain and limit the spacing of the core wires in the first direction, preventing the core wires from shifting, crossing, or contacting during assembly or use. This not only simplifies the wire separation and shaping process and improves production efficiency, but also provides stable structural constraints on the core wires by clamping them outside the core wires. This improves the problem of poor product consistency caused by differences in manual operation, increases product yield, and ensures the stability of differential signal transmission.

Detailed Implementation

[0048] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of this application.

[0049] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0051] Please refer to Figures 1 to 14 This application embodiment of the cable connector assembly 10 includes a cable 1 and a retaining clip 2. The cable 1 includes two core wires 11 and a shielding layer 12 covering the two core wires 11. The two core wires 11 are arranged side by side in a first direction, and one end of each core wire 11 protrudes outside the shielding layer 12. The retaining clip 2 is an elastic, integrally molded part. The retaining clip 2 includes two flaps 21 and two connecting portions 22. The two flaps 21 are arranged opposite to each other in a second direction, wherein the second direction is perpendicular to the first direction. Each flap 21 has a first side 21a and a second side 21b arranged opposite to each other in the first direction. The connecting portion 22 connects the first side 21a of the two flaps 21, and an opening slit 23 is formed between the second sides 21b of the two flaps 21. Two guide channels 212 are formed between the two flaps 21, one guide channel 212 for holding one core wire 11 and the other guide channel 212 for holding the other core wire 11.

[0052] In this embodiment, the fixing clip 2 has an opening slit 23, which facilitates the insertion of two core wires 11 between the two segments 21. The two guide channels 212 can respectively fix the two core wires 11. The spacing of the core wires 11 in the first direction is constrained by the guide channels 212, which prevents the core wires 11 from shifting, crossing or contacting during assembly or use. This not only simplifies the wire separation and shaping steps and improves production efficiency, but also provides stable structural constraint on the core wires 11 by clamping them outside. This improves the problem of poor product consistency caused by differences in manual operation, improves product yield, and ensures the stability of differential signal transmission.

[0053] In some embodiments, the opening slit 23 has an open state and a closed state relative to each other. When the opening slit 23 is in the open state, the two core wires 11 can be installed between the two segments 21. The methods by which the two core wires 11 are installed between the two segments 21 can include multiple methods, at least including transverse installation along a first direction, or insertion installation from back to front along the extension direction of the fixing clip 2. This application does not limit the installation method of the two core wires 11 between the two segments 21. When the opening slit 23 is in the closed state, the fixing clip 2 is used to clamp the two core wires 11 between the two segments 21, thereby separating the two core wires 11 in the first direction and guiding the two core wires 11 to extend along a preset direction.

[0054] In this embodiment, the fixing clip 2 has an openable slit 23. When the slit 23 is open, it is convenient to insert two core wires 11 between two petals 21. When the slit 23 is closed, the two petals 21 can cooperate with each other to form a stable clamp on the core wires 11 and effectively separate the core wires 11 in the first direction. At the same time, it guides the two core wires 11 to extend along a preset direction. This not only simplifies the wire separation and shaping steps and improves production efficiency, but also provides stable structural constraints on the core wires 11 by clamping them outside. This improves the problem of poor product consistency caused by differences in manual operation, improves product yield, and provides a guarantee for the stability of differential signal transmission.

[0055] In some embodiments, the fixing clip 2 is elastic, and the opening slit 23 is in a closed state in its natural state. Please refer to [reference needed]. Figures 11 to 13 The fixing clip 2 can deform under external force to make the opening slit 23... Figure 13 The closed state shown changes to Figure 14 The opening state is shown. The fixing clip 2 can also deform to allow the opening slit 23 to... Figure 14 The opened state shown is restored as follows Figure 13 The closed state is shown.

[0056] In this embodiment, the opening slit 23 is closed in its natural state, allowing the opening slit 23 of the fixing clamp 2 to remain closed during production and transportation, thus improving the transportability and stability of the fixing clamp 2. Furthermore, because the fixing clamp 2 is elastic, it can undergo elastic deformation. Even if an external force is applied to the fixing clamp 2 to open the opening slit 23, it will not cause permanent structural damage or functional failure, and can stably maintain its ability to repeat deformation and reset. After the external force is removed, the fixing clamp 2 can rely on its own elastic restoring force or, relying on its own elastic restoring force and other external forces, return the opening slit 23 to a closed state and clamp the core wire 11, reducing the difficulty of operation. It can also ensure the consistency of the spacing and extension direction of the core wires 11 through a continuous and stable clamping force. At the same time, the elastic fixing clamp 2 can adapt to core wires 11 within a certain diameter range, improving the versatility of the fixing clamp 2.

[0057] In one implementation, the fixing clip 2 can rely on its own elastic restoring force and other external forces to return the opening slit 23 to a closed state. As an example, when no external force is applied, the opening slit 23 of the fixing clip 2 is in a closed state. In use, a first force can be applied to the fixing clip 2 using an auxiliary tool, for example, by inserting the auxiliary tool into the opening slit 23 to change the opening slit 23 from a closed state to an open state. Then, the two core wires 11 of the cable 1 are placed between the two segments 21. The first force applied to the fixing clip 2 is then removed, and a second force is applied to the fixing clip 2 to press the opening slit 23 together, changing the opening slit 23 from an open state to a closed state.

[0058] In one implementation, the fixing clip 2 can rely on its own elastic restoring force to return the opening slit 23 to a closed state. For example, when no external force is applied, the opening slit 23 of the fixing clip 2 is in a closed state. In use, a first force can be applied to the fixing clip 2 using an auxiliary tool, such as inserting the auxiliary tool into the opening slit 23 to change the opening slit 23 from a closed state to an open state. Then, the two core wires 11 of the cable 1 are placed between the two segments 21. The first force applied to the fixing clip 2 is then removed, allowing the opening slit 23 to return to a closed state under the elastic force of the fixing clip 2 itself, clamping the two core wires 11. The transition between the closed and open states of the opening slit 23 in this application is a well-known technical solution, and there are many ways to achieve this; therefore, no specific method is described here.

[0059] In some embodiments, the fixing clip 2 is a one-piece structure. The one-piece structure eliminates the need for splicing multiple parts, reduces assembly gaps and weak points in the connection, improves the overall structural strength and stability of the fixing clip 2, and ensures that the fixing clip 2 is not prone to breakage or loosening during deformation and clamping.

[0060] In one implementation, the fixing clip 2 is a one-piece metal stamping part. The metal stamping process enables high-precision mass production, ensuring consistency in the dimensional parameters of each fixing clip 2, reducing product performance fluctuations caused by structural differences, simplifying the production process, improving production efficiency, and reducing manufacturing costs. Simultaneously, the metal material itself possesses excellent elastic recovery properties and durability, enabling the fixing clip 2 to stably maintain its elastic deformation and reset capability during long-term use, further ensuring the reliability of clamping the core wire 11 and the consistency of wire branching, thereby improving the service life and quality stability of the cable connector assembly 10.

[0061] In some embodiments, at least one of the two lobes 21 is recessed toward the other lobe 21 to form a recessed structure 211 and to construct two guide channels 212 located on both sides of the recessed structure 211 in a first direction.

[0062] In this embodiment, the guide channel 212 formed by the recessed structure 211 guides the core wire 11, eliminating the need for repeated manual calibration of the core wire 11 position during assembly. This simplifies the wire separation and shaping process and reduces product inconsistency caused by manual alignment deviations. Furthermore, the two guide channels 212 can respectively hold two core wires 11, constraining the spacing of the core wires 11 in the first direction. This prevents the core wires 11 from shifting, crossing, or contacting during assembly or use, ensuring a smooth transition in spacing from the exposed end of the cable 1 shielding layer 12 to the connector adapter end (center conductor). Moreover, the recessed structure 211 can be formed in one step using processes such as stamping, eliminating the need for milling or cutting. This not only simplifies the production process but also saves materials, reduces manufacturing costs, and makes it easier to achieve dimensional consistency in mass production. In addition, the guide channel 212 formed by the recess can form a certain clamping buffer space by relying on the elasticity of the petal 21 itself, which can better adapt to the slight difference in the diameter of the core wire 11 and avoid the problem of being too loose or too tight due to the fixed size of the guide channel 212 opened by the block structure.

[0063] In one implementation, when the opening slit 23 is closed, the outer surface of the core wire 11 abuts against the inner wall of the guide channel 212, thereby further ensuring the stable clamping of the core wire 11 and preventing relative movement of the two core wires 11.

[0064] As one implementation method, please refer to Figures 11 to 14The two lobes 21 are symmetrically arranged in the second direction. This symmetrical structure allows the clamping clip 2 to experience more balanced stress during elastic deformation and recovery, preventing structural deformation or shortened service life due to stress concentration on one side, and ensuring the stability and smoothness of the opening and closing action of the slot 23. Simultaneously, the inner walls of the two guide channels 212 formed by the symmetrically arranged lobes 21 are closer to a circular surface, thus better conforming to the outer contour of the circular core wire 11, increasing the contact area between the core wire 11 and the inner wall of the guide channel 212, improving clamping stability, and preventing the core wire 11 from shaking or rotating within the guide channel 212, further ensuring the overall stability and reliability of the cable connector assembly 10. Furthermore, the symmetrical structure reduces processing difficulty and improves the consistency of product dimensional accuracy; during assembly, there is no need to distinguish between the two lobes 21, simplifying the operation process.

[0065] As an example, please refer to Figures 11 to 13 The two lobes 21 are recessed towards the other lobe 21 to form a recessed structure 211 and construct two guide channels 212 located on both sides of the recessed structure 211 in a first direction. In this embodiment, the two lobes 21 are recessed towards the other lobe 21 to construct two guide channels 212 on both sides of the first direction, making the cross-section of the guide channels 212 more likely to present a symmetrical arc-shaped profile, thereby better fitting the outer contour of the circular core wire 11 and making the core wire 11 more evenly stressed. Moreover, compared to only one lobe 21 being recessed towards the other lobe 21, the two lobes 21 being recessed towards the other lobe 21 can make the recess distance of a single lobe 21 relatively smaller, thereby reducing the stress load on a single lobe 21 during deformation, avoiding material fatigue or elastic decay caused by excessive recess on one side, and extending the service life of the fixing clip 2.

[0066] It should be noted that in other embodiments, only one lobe may form a recessed structure in the direction of approaching the other lobe, while the other lobe is not recessed.

[0067] In one implementation, when the opening slit 23 is closed, the recessed structure 211 of the petal 21 can abut against the other petal 21. For example, when the two petals 21 are recessed towards the other petal 21 to form the recessed structure 211, the recessed structures 211 of the two petals 21 can abut against each other, thereby further ensuring stable clamping of the core wire 11 and preventing relative movement of the two core wires 11.

[0068] It should be noted that actual production may involve manufacturing errors. Therefore, to ensure manufacturing performance, a tolerance gap can be reserved between the recessed structures 211 of the two petals 21. This prevents the two petals 21 from abutting against each other when the opening slit 23 is closed due to manufacturing errors, thus ensuring that the two petals 21 can clamp the core wire 11. In other words, during actual production, a tolerance gap can be reserved between the recessed structures 211 of the two petals 21 to prevent the two petals 21 from failing to clamp the core wire 11 due to the guide channel 212 being too large in the second direction.

[0069] In some implementation methods, please refer to Figure 10 The fixing clip 2 has a first receiving space 213 and a second receiving space, which are arranged sequentially along the axial direction of the cable 1. The shielding layer 12 is fixed in the first receiving space 213, and the second receiving space is divided into two guide channels 212 by a recessed structure 211. The two guide channels 212 are respectively connected to the first receiving space 213.

[0070] In this embodiment, the first receiving space 213 secures the shielding layer 12, ensuring stable fixation of the cable 1's shielding structure. This prevents the shielding layer 12 from loosening or shifting, which could affect signal anti-interference performance. Furthermore, the shielding layer 12 and the core wire 11 are integrated into the fixing clamp 2, eliminating the need for additional components and simplifying the overall assembly process. The first receiving space 213 and the second receiving space are sequentially arranged along the axial direction of the cable 1. The second receiving space is divided into two guide channels 212 by a recessed structure 211. These guide channels 212 are connected to the first receiving space 213, allowing the core wire 11 to naturally extend from within the shielding layer 12 to the guide channels 212, further enhancing the product's structural stability and electrical reliability.

[0071] In some implementation methods, please refer to Figure 4 , Figure 5 as well as Figures 10 to 12Each segment 21 includes a first clamping body 214, a transition body 215, and a second clamping body 216, which are sequentially connected as a single unit along the axial direction of the cable 1. The width of the second clamping body 216 in the first direction is greater than the width of the first clamping body 214 in the first direction. The transition body 215 extends from the second clamping body 216 toward the first clamping body 214 and connects to it. Furthermore, as the transition body 215 extends from the second clamping body 216 toward the first clamping body 214, the two sides of the transition body 215 gradually approach each other in the first direction until they connect to the first clamping body 214, thereby achieving a smooth transition from the second clamping body 216 to the first clamping body 214. The first clamping body 214 of the two petals 21 surrounds to form a first receiving space 213, the transition body 215 of the two petals 21 and the second clamping body 216 surround to form a second receiving space, and the transition body 215 and the second clamping body 216 of at least one of the two petals 21 are recessed toward the other petal 21 to form a recessed structure 211.

[0072] In this embodiment, the first clamping body 214 is narrower in the first direction than the second clamping body 216. The first receiving space 213 enclosed by the first clamping body 214 can be adapted to the outer diameter of the shielding layer 12, thus achieving a tight hold on the shielding layer 12. The second clamping body 216 is wider than the first clamping body 214. With the smooth transition of the transition body 215 from the second clamping body 216 to the first clamping body 214, it can provide more space for the core wire 11 to branch, and can also disperse stress through the gradual structure, avoiding the risk of material fatigue or fracture caused by abrupt width changes. The recessed structure 211 formed by the transition body 215 and the second clamping body 216 can construct a guide channel 212 in the second receiving space. Moreover, the smooth transition structure makes the path of the core wire 11 smoother when it extends from the first receiving space 213 to the second receiving space, allowing the core wire 11 to bend more smoothly. Meanwhile, the three-section integrated structure enhances the overall rigidity and stability of the segment 21, ensuring a more uniform holding force of the first receiving space 213 on the shielding layer 12 and the second receiving space on the core wire 11, effectively improving the structural reliability of the cable connector assembly 10 during assembly and use. Furthermore, the fixing clip 2 in this embodiment can be formed in one piece using a stamping process, eliminating the need for complex multi-process machining and avoiding material loss that may occur during cutting, milling, and other processes. Moreover, stamping enables gradual and smooth transitions in the dimensions of the first clamping body 214, the transition body 215, and the second clamping body 216, ensuring consistency in the structural parameters of each part and further guaranteeing the stability of the fixing clip 2's performance and ease of assembly.

[0073] As one implementation method, please refer to Figure 12The connecting portion 22 connects the two first clamping bodies 216 of the two petal portions 21. That is, no connecting portion 22 is provided between the first clamping bodies 214 of the two petal portions 21 and between the transition bodies 215 of the two petal portions 21; the first clamping bodies 214 of the two petal portions 21 are not connected, and the transition bodies 215 of the two petal portions 21 are not connected. The two petal portions 21 and the connecting portion 22 together define a notch 24 extending from between the first clamping bodies 214 of the two petal portions 21 to between the transition bodies 215 of the two petal portions 21. The notch 24 reduces the structural constraints in the areas of the first clamping bodies 214 and the transition bodies 215. Compared to the second clamping body 216, the first clamping body 214 is narrower in the first direction, and the spatial structure of the transition body 215 is more complex. If a connecting part 22 is provided at the first clamping body 214 and the transition body 215, it will not only cause the connecting part 22 to bind the petal 21 more tightly, increasing the resistance when the opening slit 23 opens and closes, which is not conducive to the smooth deformation of the petal 21 under external force, but also make it difficult to ensure that the first clamping body 214 and the transition body 215 can smoothly return to their initial state when the opening slit 23 returns to the closed state. Therefore, the notch slit 24 can make the opening and closing action of the opening slit 23 more flexible and effortless, avoiding the problem of the opening slit 23 not opening and closing smoothly due to the obstruction of the connecting part 22, as well as the problem of the first clamping body 214 and the transition body 215 being difficult to reset, further improving the convenience of assembly operation and the structural accuracy of the fixing clamp 2.

[0074] In some embodiments, the cable connector assembly 10 further includes a first welding structure (not shown) disposed on the second side 21b of the two segments 21, which is used to keep the opening slit 23 closed. After the cable 1 is placed in the retaining clip 2 and the opening slit 23 is closed, the second side 21b of the two segments 21 can be fixed by welding to prevent the opening slit 23 from opening again, thus ensuring the stability of the core wire 11 and the shielding layer 12 within the retaining clip 2. As an example, the first welding structure can be disposed within the opening slit 23 and close the opening slit 23.

[0075] In some implementation methods, please refer to Figure 4 , Figure 5 , Figure 9 and Figure 10 The core wire 11 includes an inner conductor 111 and an insulating layer 112. The insulating layer 112 covers the inner conductor 111. One end of the inner conductor 111 is exposed outside the insulating layer 112. The inner conductor 111 exposed outside the insulating layer 112 is exposed outside the fixing clip 2. The inner conductor 111 is insulated from the fixing clip 2. One end of the insulating layer 112 is exposed outside the shielding layer 12. At least part of the insulating layer 112 exposed outside the shielding layer 12 is clamped between two lobes 21. Part of the shielding layer 12 is clamped between two lobes 21. The shielding layer 12 is electrically connected to the fixing clip 2.

[0076] In this embodiment, the inner conductor 111 is exposed outside the fixing clamp 2 and insulated from it. This avoids signal short circuits or interference caused by electrical connection between the inner conductor 111 and the fixing clamp 2, ensuring stable signal transmission by the inner conductor 111. The portion of the insulating layer 112 exposed outside the shielding layer 12 is clamped between the two segments 21. The clamping force of the fixing clamp 2 secures the core wire 11, preventing the inner conductor 111 from deviating from the preset path and ensuring stable connection between the inner conductor 111 and the center conductor 3. The partial shielding layer 12 being clamped between the two segments 21 and electrically connected to the fixing clamp 2 not only optimizes the product's electrical performance, shortens the return path, and reduces eddy currents, but also prevents the shielding effect from decreasing due to loosening of the shielding layer 12, thus improving the electrical performance and structural stability of the cable connector assembly 10.

[0077] In some implementation methods, please refer to Figure 4 , Figure 5 , Figure 9 and Figure 10 The shielding layer 12 includes an aluminum foil layer 121 and a metal braided layer 122. The aluminum foil layer 121 covers the outside of the insulating layer 112, and the metal braided layer 122 covers the outside of the aluminum foil layer 121. One end of the aluminum foil layer 121 protrudes outside the metal braided layer 122, and a portion of the aluminum foil layer 121 is clamped between two segments 21. The aluminum foil layer 121 is electrically connected to the fixing clip 2. The cable connector assembly 10 also includes a cable clip 7, which is crimped onto the metal braided layer 122. The crimping of the cable clip 7 onto the metal braided layer 122 effectively secures the metal braided layer 122, preventing it from loosening or shifting, and avoiding any impact on shielding integrity due to the metal braided layer 122 detaching.

[0078] In some implementation methods, please refer to Figures 1 to 5 , Figure 9 and Figure 10 The cable connector assembly 10 also includes two center conductors 3 and an outer conductor composite 10a. The two center conductors 3 are crimped one-to-one to the ends of the two core wires 11 exposed in the shielding layer 12, and each center conductor 3 is electrically connected to its corresponding core wire 11. The center conductors 3, the retaining clip 2, and a portion of the cable 1 are held within the outer conductor composite 10a, and the center conductors 3 are insulated from the outer conductor composite 10a. The retaining clip 2 and the shielding layer 12 are electrically connected to the outer conductor composite 10a. This electrical connection between the retaining clip 2, the shielding layer 12, and the outer conductor composite 10a forms a continuous shield, extending the electromagnetic protection function of the shielding layer 12 to the outer conductor composite 10a. The overall shielding structure further blocks external electromagnetic interference and prevents internal signal leakage.

[0079] As one implementation method, please refer to Figure 2 , Figure 6, Figure 7 , Figure 9 and Figure 10 The outer conductor composite 10a includes an insulator 4 and an electrically connected first shielding shell 5 and second shielding shell 6. The insulator 4 is pressed into one end of the first shielding shell 5, and the second shielding shell 6 is fixed to the outside of the end of the first shielding shell 5 where the insulator 4 is located, thereby holding the insulator 4 between the first shielding shell 5 and the second shielding shell 6. The center conductor 3 is inserted into the insulator 4 from the end of the first shielding shell 5 away from the insulator 4. The center conductor 3 is insulated from the first shielding shell 5 and the second shielding shell 6 through the insulator 4. The end of the first shielding shell 5 away from the insulator 4 is pressed onto the outside of the cable 1 and electrically connected to the shielding layer 12.

[0080] In this embodiment, the end of the first shielding shell 5 furthest from the insulator 4 is pressed against the outside of the shielding layer 12, enabling an electrical connection between the first shielding shell 5 and the shielding layer 12. This extends the shielding function of the cable 1 shielding layer 12 to the outer conductor composite 10a. The second shielding shell 6 cooperates with the first shielding shell 5 to hold the insulator 4 within both the first and second shielding shells. This not only enhances the overall electromagnetic shielding effect but also allows for quick and stable fixation of the insulator 4, ensuring the stability of the insulation fit between the center conductor 3 and the insulator 4 and avoiding the risk of signal short circuits caused by the displacement of the insulator 4.

[0081] As one implementation method, please refer to Figure 7 , Figure 9 and Figure 10The first shielding shell 5 is a hollow, one-piece structure. The first shielding shell 5 includes a first shell portion 51, a second shell portion 52, and a third shell portion 53, which are sequentially arranged and connected as a single unit along the axial direction of the cable 1. The first shell portion 51 includes a first shell section 511 and a first transition section 512. The first transition section 512 gradually narrows from the first shell section 511 and extends to connect with the second shell portion 52. The second shell portion 52 includes a second shell section 521 and a second transition section 522. The second shell section 521 extends from the first transition section 512 and connects with the second transition section 522. The second transition section 522 gradually expands from the second shell section 521 and extends to connect with the third shell portion 53. As an example, one end of the insulator 4 is inserted into the first housing portion 51, and the other end of the insulator 4 protrudes from the first housing portion 51. The outer surface of the end of the insulator 4 inserted into the first housing portion 51 abuts against the inner wall of the first transition section 512, thereby effectively limiting the position of the insulator 4 within the first shielding shell 5 and preventing the insulator 4 from being over-inserted into the first shielding shell 5. The fixing clip 2 is fixed within the second housing portion 52, and a portion of the outer surface of the second clamping body 216 of the fixing clip 2 abuts against the inner wall of the second housing section 521. This not only ensures a stable and effective electrical connection between the fixing clip 2 and the second housing portion 52, but also allows the second transition section 522 to gradually expand from the second housing section 521, enabling the fixing clip 2 to be smoothly inserted into the second housing portion 52 and guiding the fixing clip 2 into the second housing section 521, making assembly easier. The cable 1 also includes an outer sheath 13 covering the shielding layer 12. The outer sheath 13 can be an insulating plastic layer, and the shielding layer 12 protrudes from one end of the outer sheath 13. The inner wall of the third shell 53 abuts against the outer surface of the shielding layer 12 and the outer surface of the outer sheath 13. The third shell 53 forms a stable clamp and fixation for the shielding layer 12 and the outer sheath 13. This can prevent the shielding layer 12 from being loosened or displaced during assembly or use, thus affecting the electromagnetic shielding effect. It can also enhance the connection sealing between the cable 1 and the first shielding shell 5 by tightly fitting the outer sheath 13 with the third shell 53, reducing the risk of external dust, moisture and other impurities entering.

[0082] As one implementation method, please refer to Figure 7 and Figure 9The second shielding shell 6 is a hollow, one-piece structure. The second shielding shell 6 includes a fourth shell portion 61, a fifth shell portion 62, and a sixth shell portion 63, which are sequentially arranged and connected as one piece along the axial direction of the cable 1. The fifth shell portion 62 includes a fifth shell section 621 and a fifth transition section 622, which gradually expands from the fourth shell portion 61 and extends to connect with the fifth shell section 621. The sixth shell portion 63 includes a sixth shell section 631 and a sixth transition section 632, which gradually expands from the fifth shell section 621 and extends to connect with the sixth shell section 631. As an example, one end of the insulator 4 exposed in the first shielding shell 5 is inserted into the fifth shell portion 62 by the sixth shell portion 63, and the outer surface of the end of the insulator 4 inserted into the fifth shell portion 62 abuts against the inner wall of the fifth transition section 622, thereby preventing the insulator 4 from protruding from the fourth shell portion 61 to the outside of the second shielding shell 6, further ensuring structural stability. The first shell portion 51 of the first shielding shell 5 is inserted into the second shielding shell 6, and the outer surface of the end of the first shell portion 51 away from the second shell portion 52 abuts against the inner wall of the sixth transition section 632, thereby effectively restricting the position of the first shielding shell 5 in the second shielding shell 6 and preventing the first shielding shell 5 from being over-inserted into the second shielding shell 6.

[0083] In some implementation methods, please refer to Figure 6 and Figure 7 The second shielding shell 6 also includes a protrusion 633. The protrusion 633 protrudes from the inner wall of the second shielding shell 6 and abuts against the first shielding shell 5. As an example, the protrusion 633 can be formed by stamping, with the protrusion 633 recessed inward relative to the outer surface of the second shielding shell 6 and protruding towards the first shielding shell 5 relative to the inner surface of the second shielding shell 6. It should be noted that the protrusion can also be obtained by other processing methods, which can be set according to the actual situation, and will not be elaborated here. As one implementation, the protrusion 633 can protrude inward relative to the sixth shell segment 631 and abut against the outer periphery of the first shell segment 511.

[0084] In this embodiment, the protrusion 633 abutting against the first shielding shell 5 can enhance the tightness of the fit between the first shielding shell 5 and the second shielding shell 6. This not only improves the mechanical connection strength and prevents the two shielding shells from loosening, ensuring the structural stability of the outer conductor composite 10a, but also ensures the continuity of the electrical connection, avoiding the occurrence of a break in the shielding circuit due to poor contact, thereby ensuring the shielding effect of the outer conductor composite 10a.

[0085] In some implementation methods, please refer to Figure 6 and Figure 7The second shielding shell 6 has a through hole 634 extending through it. The cable connector assembly 10 also includes a second welding structure (not shown), which is disposed within the through hole 634 to fix the first shielding shell 5 and the second shielding shell 6, preventing relative loosening of the first shielding shell 5 and the second shielding shell 6, and ensuring the structural stability and shielding performance continuity of the outer conductor composite 10a. In one embodiment, the through hole 634 is located in the sixth shell segment 631. As an example, there are multiple protrusions 633 and multiple through holes 634. The multiple protrusions 633 and multiple through holes 634 are arranged circumferentially and alternately around the sixth shell segment 631, which allows the limiting force of the second shielding shell 6 on the first shielding shell 5 and the welding fixing force to be evenly distributed circumferentially, avoiding local stress concentration and improving the connection stability and shielding continuity of the first shielding shell 5 and the second shielding shell 6. For example, there are four protrusions 633 and four through holes 634. Two protrusions 633 are spaced apart and symmetrically disposed at one end of the second shielding shell 6 in the second direction, and another two protrusions 633 are spaced apart and symmetrically disposed at the other end of the second shielding shell 6 in the second direction. Two through holes 634 are spaced apart and symmetrically disposed at one end of the second shielding shell 6 in the first direction, and another two through holes 634 are spaced apart and symmetrically disposed at the other end of the second shielding shell 6 in the first direction, and there is also a gap between the through holes 634 and the protrusions 633.

[0086] In some embodiments, the cable connector assembly 10 further includes a third welding structure (not shown), which is used to weld and fix the first shielding shell 5 and the fixing clip 2, thereby improving the connection stability and electrical conductivity of the first shielding shell 5 and the fixing clip 2. In one embodiment, the third welding structure is used to weld and fix the second shell segment 521 and the fixing clip 2. For another embodiment, please refer to... Figure 9 and Figure 10 After the cable clamp 7 is pressed onto the metal braided layer 122, the metal braided layer 122 can be folded outward to wrap around the cable clamp 7. The folded metal braided layer 122 is fixed between the outer conductor composite 10a and the cable clamp 7 and is electrically connected to the outer conductor composite 10a, so that the metal braided layer 122 forms a tight fit with the cable clamp 7 and the outer conductor composite 10a, preventing the metal braided layer 122 from being damaged due to lack of support, and further enhancing the electrical connection stability between the shielding layer 12 and the outer conductor composite 10a.

[0087] In some implementation methods, please refer to Figure 7The first shielding shell 5 includes a sheet 531, and the third shell portion 53 is formed from the sheet 531. Specifically, the sheet 531 is a sheet-like structure with a preset curvature, and one end of the sheet 531 is connected to the second shell portion 52 in the axial direction of the cable 1. As an example, the sheet 531 can be integrally stamped with the first shell portion 51 and the second shell portion 52. When forming the third shell portion 53, the sheet-like sheet 531 is bent and enclosed in the direction close to the cable, so that the edges 531a of the sheet 531 are joined together, thereby forming a cylindrical third shell portion 53 fixed to the outside of the cable 1. During the enclosing process of the sheet 531, the sheet 531 can be tightly attached to the surface of the cable 1 by riveting, which can firmly clamp the folded metal braided layer 122, prevent the metal braided layer 122 from loosening or shifting, and thus ensure the continuity of shielding.

[0088] In one embodiment, the cable connector assembly 10 further includes a fourth welding structure (not shown). If a butt joint gap exists after the sheath 531 is closed, the fourth welding structure can weld and fix the splice of the sheath 531 itself, i.e., the edge 531a of the sheath 531, to ensure the integrity of the cylindrical structure of the third shell 53. If it is necessary to further enhance the connection reliability between the sheath 531 and the cable 1, the fourth welding structure can also weld and fix the sheath 531 and the cable 1 simultaneously. For example, in some examples, the fourth welding structure can weld and fix the sheath 531 and the folded metal braided layer 122. In some examples, the fourth welding structure can weld and fix the sheath 531 and the outer sheath 13. In some examples, the fourth welding structure can weld and fix the sheath 531 and the folded metal braided layer 122, and weld and fix the sheath 531 and the outer sheath 13.

[0089] As an example, the first, second, third, and fourth welded structures can be formed by laser spot welding. Alternatively, the above-mentioned welded structures can also be formed by other welding methods, which can be set according to the actual situation, and will not be elaborated here.

[0090] Please refer to Figure 15 Curve S100 is the impedance curve of the cable connector assembly 10 in this embodiment, and curve S200 is the impedance curve of the comparative cable connector assembly, wherein the comparative cable connector assembly does not include the fixing clip. Figure 15 The area C corresponding to the cable connector assembly 10 is provided with a fixing clip 2. Figure 15 As can be seen from part C, compared to the comparative example, the impedance of this embodiment is closer to 100 ohms. In other words, the cable connector assembly 10 in this embodiment achieves better impedance control because it includes the fixing clip 2.

[0091] Please refer to Figure 16Curve S300 is the return loss curve at the region where the fixing clip 2 is provided in the cable connector assembly 10 of this embodiment. The comparative cable connector assembly does not include the fixing clip, and curve S400 is the return loss curve of the core wire branching region of the comparative cable connector assembly. Figure 16 As can be seen, compared with the comparative example, the cable connector assembly 10 in this embodiment can achieve a better return loss value.

[0092] As an example, the assembly method of the cable connector assembly 10 includes the following steps:

[0093] Step 1: Provide cable 1. Cable 1 includes a core wire 11, a shielding layer 12, and an outer sheath 13 arranged sequentially from the inside out. The core wire 11 includes an inner conductor 111 and an insulation layer 112 arranged sequentially from the inside out. The shielding layer 12 includes an aluminum foil layer 121 and a metal braided layer 122 arranged sequentially from the inside out. After providing cable 1, circumferentially cut the outer sheath 13 and remove excess outer sheath 13, so that one end of the metal braided layer 122 is exposed outside the outer sheath 13.

[0094] Step two, provide cable clip 7, and rivet cable clip 7 to one end of metal braided layer 122 near outer sheath 13. Bend metal braided layer 122 outward and fold metal braided layer 122 towards outer sheath 13 to wrap cable clip 7 inside metal braided layer 122.

[0095] Step 3: Circumferentially cut the aluminum foil layer 121 and remove the excess aluminum foil layer 121, so that one end of the insulating layer 112 is exposed outside the aluminum foil layer 121. Then circumferentially cut the insulating layer 112 and remove the excess insulating layer 112, so that one end of the inner conductor 111 is exposed outside the insulating layer 112.

[0096] Step 4: Provide the center conductor 3 and rivet the center conductor 3 to the inner conductor 111 at one end exposed outside the insulation layer 112.

[0097] Step 5: Provide the fixing clip 2, opening the slot 23 of the fixing clip 2 into an open state. After the opening slot 23 of the fixing clip 2 is open, place the exposed portion of the aluminum foil layer 121 of the cable 1 into the opened first receiving space 213, and place one core wire 11 into one guide channel 212, and place the other core wire 11 into the other guide channel 212. The insulation layer 112 of the core wire 11 placed in the guide channel 212 is in contact with the inner wall of the guide channel 212, and the inner conductor 111 is located outside the guide channel 212.

[0098] Step six, change the opening slit 23 of the fixing clip 2 to a closed state so that the two core wires 11 are clamped between the two petals 21, and then form a first welding structure at the opening slit 23 to keep the opening slit 23 closed, to obtain a wire harness composite 10b assembled from the cable 1, the cable clip 7, the center conductor 3 and the fixing clip 2.

[0099] Step 7: Provide the insulator 4 and the first shielding shell 5, and press the insulator 4 into the first shell portion 51 of the first shielding shell 5.

[0100] Step 8: Provide a second shielding shell 6, insert and fix the second shielding shell 6 to the outside of the first shell portion 51 of the first shielding shell 5, and at the same time insert the insulator 4 from the sixth shell portion 63 into the fifth shell portion 62, thereby fixing the insulator 4 between the first shielding shell 5 and the second shielding shell 6, to obtain an outer conductor composite 10a assembled from the first shielding shell 5, the second shielding shell 6 and the insulator 4.

[0101] Step nine: Insert the wire harness composite 10b into the outer conductor composite 10a through the third shell 53, so that the center conductor 3 is fixed in the insulator 4. Then, press and fix the third shell 53 of the first shielding shell 5 to the metal braided layer 122 and the outer sheath 13 of the cable 1 to obtain the cable connector assembly 10.

[0102] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the scope of protection of this patent application should be determined by the appended claims.
