Description

Technical Field

[0001] This utility model relates to the field of signal transmission cable technology, and in particular to a connecting wire harness. Background Technology

[0002] In modern electronic devices, the USB Type-C interface is widely used due to its versatility (high-speed data, video, power supply), and it often needs to coexist with the essential RJ-45 Ethernet port in a limited space.

[0003] However, when devices use Type-C to Type-C cables for high-speed data transmission, the high-speed Type-C data signal is highly susceptible to electromagnetic interference (EMI) generated by nearby RJ-45 ports and their cables, and vice versa. This is mainly due to space constraints and signal coupling, leading to signal integrity degradation and seriously threatening the data transmission rate and stability. Utility Model Content

[0004] The main objective of this invention is to propose a connecting harness that can avoid interference with adjacent RJ-45 ports, thereby improving the data transmission stability of the connecting harness.

[0005] To achieve the above objectives, this utility model proposes a connecting harness, which includes two connectors and a cable connecting the two connectors. Each connector has an inner surface as a connecting surface, and the cable is connected to the two connecting surfaces. Both ends of the cable extend obliquely out of the connecting surfaces to form a clearance space.

[0006] In one embodiment, the two ends of the cable are inclined upward or inclined downward relative to the connecting surface.

[0007] In one embodiment, the axial extension directions of both ends of the cable are set at an angle to the connecting surface, and the angle is within 30 degrees to 60 degrees.

[0008] In one embodiment, the side surface of the connector adjacent to the connection surface is the output surface, and the output surface is provided with a plug.

[0009] In one embodiment, the cable is positioned away from the plug at the point where it exits the connector surface.

[0010] In one embodiment, the connector includes:

[0011] An outer mold, wherein the outer mold has an inner cavity and one side surface is a connecting surface;

[0012] PCB, the PCB being mounted in the inner cavity and connected to one end of the cable; and

[0013] The guide portion is located on the connecting surface and has a guide groove communicating with the inner cavity. The extension direction of the guide groove is set at an angle to the connecting surface, so that the cable is transmitted obliquely from the guide groove.

[0014] In one embodiment, the opening of the guide groove is elliptical in shape.

[0015] In one embodiment, the outer mold has a recess on the side adjacent to the output surface, the recess being used to accommodate the protruding portion of the device port.

[0016] In one embodiment, the two plugs are USB-C type.

[0017] The technical solution of this utility model includes a connecting harness comprising two connectors and a cable connecting the two connectors. One inner surface of each connector serves as a connecting surface. The cable connects to the two connecting surfaces, with both ends of the cable extending obliquely through the connecting surfaces to create clearance space. This oblique extension design alters the cable's spatial orientation, allowing the cable to exit at an angle and form a physical isolation space. This avoids interference with adjacent RJ-45 ports, reduces the electromagnetic coupling strength between high-speed signal lines and adjacent port cables, maintains data transmission stability, and thus improves the data transmission stability of the connecting harness.

[0029] In current technologies, the layout of electronic device interfaces is becoming increasingly compact, and the coexistence of multi-functional ports is leading to increasingly prominent signal interference problems. Taking a typical scenario where Type-C interfaces and RJ-45 ports are arranged adjacently as an example, traditional cables use a vertical connection method, resulting in parallel routing areas between high-speed signal lines and Ethernet cables. This layout exacerbates electromagnetic coupling between cables, degrades signal integrity, and makes it difficult to reduce interference through physical isolation, especially in confined spaces.

[0030] To address the aforementioned issues, it was discovered during the research and development process that parallel routing of cables to adjacent ports was the primary cause of electromagnetic interference.

[0031] Therefore, please refer to Figures 1 to 3This application proposes a connecting harness, including two connectors 10 and a cable 20 connecting the two connectors 10.

[0032] In this example, the two connectors 10 are identical, and each connector 10 can be roughly divided into four parts: PCB, plug, inner mold, and outer mold. In this example, the plug is a USB-compatible Type-C male connector. The plug includes multiple conductive terminals, one end of each conductive terminal protruding from the front of the male connector, and the other end soldered to the front solder points of the PCB of the connector 10. The multiple end solder points on the PCB are used for cable connection. After the plug and cable are soldered, an inner mold is formed on the PCB using a relatively low-temperature, low-pressure injection molding process to protect the front and rear solder points; finally, an outer mold is formed outside the inner mold using a relatively high-temperature, high-pressure injection molding process for further protection.

[0033] The outermost side surface of each connector 10 is a connecting surface 10a, and the side surfaces of the two connectors 10 face each other. The cable 20 is connected to the two connecting surfaces 10a, and the two ends of the cable 20 extend out of the connecting surfaces 10a at an angle to form a clearance space with the adjacent ports.

[0034] The connecting surface 10a refers to the surface on the connector 10 used to fix the direction of the cable 20. This can be achieved using a planar structure design to ensure the consistency of the cable 20's fixed position and angle on the connector 10. Inclined exit refers to the cable 20 extending from the connecting surface 10a at a non-perpendicular angle. This can be achieved by adjusting the internal guide structure of the connector 10, allowing the cable 20 to form a predetermined angle when exiting. The clearance space refers to the three-dimensional gap formed between the cable 20 after its inclined extension and the port of an adjacent device. This gap is generated by controlling the angle and direction of extension and is used to isolate different signal transmission paths.

[0035] Specifically, two connectors 10 are fixed at the docking positions of the device ports, and both ends of the cable 20 are designed to extend at an angle through the connection surface 10a. When the connectors 10 are installed in the device, the angled extension path of the cable 20 creates a spatial misalignment with the cables 20 of adjacent ports. This misaligned layout shortens the length of the parallel routing area and reduces capacitive coupling between high-frequency signal lines. At the same time, the angled extension structure prevents the cable 20 from contacting the outer mold 11 of adjacent ports when bending, reducing the risk of mechanical interference. Through spatial avoidance and path optimization, electromagnetic compatibility is improved within a compact layout.

[0036] Compared to existing technologies, the traditional vertical exit method of cable 20 results in long parallel runs with adjacent port cables 20. This solution changes the spatial orientation of cable 20 through an angled exit design, causing different signal transmission paths to intersect three-dimensionally rather than be planar parallel. This structural innovation effectively shortens the interference coupling area under the same spatial conditions, while maintaining the miniaturization of connector 10.

[0037] Through the above technical solution, this application achieves physical isolation by tilting the cable 20 outwards to create a space in compact electronic device layouts. This reduces the electromagnetic coupling strength between high-speed signal lines and adjacent port cables 20, maintaining data transmission stability. This solution optimizes electromagnetic compatibility within a limited space, avoiding data transmission rate degradation due to signal interference.

[0038] Please see Figures 1 to 3 This application further proposes that the two ends of the cable 20 are inclined upward or inclined downward relative to the connecting surface 10a.

[0039] In this embodiment, the inclined upward setting means that after the end of the cable 20 passes through the connecting surface 10a, it extends upward away from the connecting surface 10a. Specifically, it can be achieved by shaping the guide groove 12a of the guide part 12 of the outer mold 11 at an upward inclined angle. This structure makes the path of the cable 20 spatially misaligned with the adjacent port in the vertical direction.

[0040] The downward tilt setting means that after the end of the cable 20 passes through the connecting surface 10a, it extends downward away from the connecting surface 10a. Specifically, it can be achieved by shaping the guide groove 12a of the guide part 12 at a downward tilt angle. This structure makes the path of the cable 20 form a reverse spatial misalignment with the adjacent port in the vertical direction.

[0041] Specifically, the cable 20 creates clearance space when the connector 10 is mated by selectively adjusting its tilt direction. When the cable 20 tilts upward, its extension path avoids the adjacent port area above the connector 10; when the cable 20 tilts downward, its extension path avoids the adjacent port area below the connector 10. This directional clearance reduces the electromagnetic coupling strength caused by parallel arrangement of the cable 20 and adjacent ports by changing their relative positional relationship. Simultaneously, the selectivity of the tilt angle allows the cable 20 to be adaptively adjusted according to the internal space constraints of the device. For example, in compact devices, an upward tilt can be used to avoid densely packed ports at the top, or in flat devices, a downward tilt can be used to avoid the bottom heat dissipation module.

[0042] Compared to existing technologies, traditional connecting cables 20 are laid out in a straight line perpendicular to the connecting surface 10a, resulting in parallel overlapping areas between the cable 20 and adjacent ports, exacerbating electromagnetic interference and occupying lateral space. This solution, through a controllable tilt design, spatially separates the cable 20 from adjacent ports, reducing the electromagnetic coupling area and providing layout space for other functional modules. This effectively reduces the electromagnetic interference intensity between the cable 20 and adjacent ports, improves the stability of high-speed data transmission, and adapts to the spatial constraints of different devices, avoiding port layout limitations caused by spatial conflicts.

[0043] Please see Figures 1 to 3 Furthermore, this application proposes that the axial extension directions of both ends of the cable 20 are set at an angle to the connecting surface 10a, and the angle is within 30 degrees to 60 degrees.

[0044] In this embodiment, the axial extension direction forming an angle with the connecting surface 10a means that the extension path of the cable 20 forms a non-perpendicular tilt angle relative to the plane of the connecting surface 10a of the connector 10. Specifically, this can be achieved by providing a guide groove 12a structure on the connecting surface 10a of the connector 10. The extension direction of the guide groove 12a forms a preset angle with the connecting surface 10a, allowing the cable 20 to pass through obliquely along the guide groove 12a. This tilt angle creates a physical clearance space for the cable 20 outside the connector 10, reducing spatial overlap with adjacent ports. The angle range of 30 to 60 degrees refers to the range of tilt angles between the cable 20's exit direction and the connecting surface 10a. This can be achieved by adjusting the tilt angle of the guide groove 12a. This range ensures that the bending radius of the cable 20 meets mechanical strength requirements while effectively creating clearance space. An angle less than 30 degrees results in insufficient clearance, while an angle exceeding 60 degrees significantly increases the bending stress of the cable.

[0045] Specifically, when cable 20 exits from connector surface 10a, its axial extension direction forms an angle with connector surface 10a, causing cable 20 to extend obliquely outside connector 10. By controlling the angle between 30 and 60 degrees, cable 20 avoids adjacent port areas while keeping its bending radius within allowable limits. For example, when connector 10 is close to an RJ-45 port, cable 20 exits at a 45-degree angle, its extension path deviating from the installation area of ​​the RJ-45 port, thereby reducing the parallel routing length between them and lowering the probability of electromagnetic coupling. Furthermore, this angle range avoids insufficient clearance due to an excessively small angle, or the risk of wire bending fatigue due to an excessively large angle.

[0046] Compared with existing technologies, existing connectors 10 typically use a layout where the cable 20 passes through the connection surface 10a perpendicularly, causing the cable 20 to directly overlap with adjacent ports in a limited space, exacerbating electromagnetic interference. This solution limits the tilt angle range, causing the cable 20 to pass through in a spatially misaligned direction with the adjacent ports, which not only does not significantly increase the volume of the connector 10, but also effectively reduces the cross area of ​​the signal coupling path.

[0047] Please see Figures 1 to 3 This application further proposes that the side surface of the connector 10 adjacent to the connection surface 10a is the output surface 10b, the output surface 10b is provided with a plug 10c, and the plug 10c is provided with multiple connection terminals for conducting electrical energy.

[0048] In this embodiment, the output surface 10b refers to the side adjacent to the connection surface 10a of the cable 20 of the connector 10. Specifically, it can be formed into a planar structure using injection molding. This plane forms a spatial perpendicular relationship with the connection surface 10a and is used to set up the signal transmission interface. The plug 10c refers to the metal conductive contact, which can be soldered to the edge area of ​​the PCB using surface mount technology and is used to establish an electrical connection with the external port.

[0049] Specifically, the planar structure of the output surface 10b forms an orthogonal layout with the connection surface 10a, thus confining the plug 10c to an independent area. When the cable 20 exits the connection surface 10a at an angle, its extension path remains spatially misaligned with the output surface 10b, and the physical isolation between the terminals and the cable 20 prevents overlap of signal transmission paths. The plug 10c is concentrated at the edge of the output surface 10b away from the exit point of the cable 20, resulting in an asymmetrical distribution of the electromagnetic radiation areas of the terminals and the cable 20, eliminating the near-field coupling effect generated by high-frequency signals passing through the cable 20 sheath. The independent layout of the output surface 10b provides an installation positioning reference for adjacent device ports, allowing the protruding portion of the external port to be embedded into the corresponding recessed area of ​​the connector 10, forming a mechanical interlock while maintaining a safe distance between the terminals and the external port.

[0050] Compared to existing technologies, traditional connectors 10 place the terminals and cable 20 outlets on two opposing surfaces. When devices have Type-C and RJ-45 ports side-by-side (such as on the side of a laptop), the vertical exit direction of the traditional through-hole cable 20 occupies horizontal space. The outer mold 11 of the Type-C cable 20 directly collides with the metal shielding shell / locking protrusion of the RJ-45 port (overlapping as shown in the red box in the figure), making simultaneous insertion impossible or requiring forced misalignment. This solution, however, separates the terminals and cable 20 outlets to different planes through an orthogonal plane layout. This spatial dimensional difference blocks the propagation path of electromagnetic interference, reducing the overlapping area of ​​electromagnetic radiation compared to planar layout solutions.

[0051] Through the above technical solution, this application achieves physical isolation between the terminal signal transmission path and the electromagnetic radiation area of ​​the cable 20, reduces near-field coupling interference caused by high-frequency signals passing through the cable 20 sheath, and provides a mechanical positioning reference for external device ports, ensuring reliable connection of the signal interface in a compact space. The spatially staggered layout of the terminals and the cable 20 allows the connector 10 to be compatible with the integrated installation requirements of various types of terminals while maintaining standard interface dimensions.

[0052] Please see Figures 1 to 3 This application further proposes that the position where the cable 20 exits from the connection surface 10a is away from the plug 10c.

[0053] In this embodiment, the cable 20 exit point refers to the contact area between the cable 20 and the connecting surface 10a when the cable 20 is led out from the connecting surface 10a. Specifically, this can be achieved by setting an exit hole in the edge area of ​​the connecting surface 10a, with the position of the exit hole maintaining a distance from the area where the plug 10c is located. Setting it away from the plug 10c means that the straight-line distance between the cable 20 exit point and the plug 10c is set to be greater than a preset threshold. Specifically, this can be achieved by arranging the exit hole in the diagonal or lateral area of ​​the plug 10c within the connecting surface 10a. This distance setting can block the electromagnetic coupling path between the cable 20 and the plug 10c.

[0054] Specifically, the exit point of cable 20 at the connection surface 10a is confined to an area far from plug 10c, thus physically isolating the transmission path of cable 20 from the signal transmission area of ​​plug 10c. When cable 20 transmits high-frequency signals, the electromagnetic field radiation range it generates is limited to a space far from plug 10c, thereby reducing the interference intensity on the signal transmission of plug 10c. Simultaneously, the spatial separation between cable 20 and plug 10c prevents physical contact between the bent section of cable 20 and plug 10c in the confined space inside the equipment, eliminating signal transmission abnormalities caused by mechanical compression. This layout simultaneously addresses both electromagnetic interference suppression and mechanical interference prevention through spatial isolation.

[0055] This solution, by adjusting the lead-out position of cable 20, can effectively reduce the electromagnetic interference intensity between cable 20 and plug 10c, eliminate the positional conflict between the two in the limited installation space, and ensure that signal transmission stability and internal space utilization of the equipment are optimized simultaneously.

[0056] Please see Figures 1 to 3This application further proposes that the connector 10 includes an outer mold 11, a PCB, and a guide portion 12. The outer mold 11 has an inner cavity, one side of which is a connecting surface 10a; the PCB is mounted in the inner cavity and connected to one end of the cable 20; the guide portion 12 is disposed on the connecting surface 10a and has a guide groove 12a communicating with the inner cavity. The extension direction of the guide groove 12a is set at an angle to the connecting surface 10a, so that the cable 20 is transmitted obliquely from the guide groove 12a.

[0057] In this embodiment, the inner cavity of the outer mold 11 refers to the enclosed space that accommodates the PCB. Specifically, it can be formed by injection molding to create a shell structure with a connecting surface 10a, providing fixed support for the PCB and constraining the connection position of the cable 20. The guide groove 12a of the guide portion 12 refers to a channel structure with a specific extension direction. Specifically, it can be formed by molding an inclined channel at a 30-60 degree angle to the connecting surface 10a, used to guide the cable 20 to pass through the connecting surface 10a at a preset angle. PCB mounting refers to the electrical connection between the circuit board and the cable 20. Specifically, the conductor of the cable 20 can be fixed to the PCB pads by soldering or crimping processes to ensure signal transmission stability.

[0058] Specifically, after the cable 20 completes its electrical connection with the PCB within the inner cavity, it is guided into the inclined guide groove 12a of the guide section 12. Because the extension direction of the guide groove 12a forms a fixed angle with the connecting surface 10a, the cable 20 is forced to change its transmission path when exiting the connecting surface 10a, resulting in an inclined extension state relative to the connecting surface 10a. This inclination angle causes the cable 20 to form a non-parallel spatial layout with adjacent ports after leaving the connector 10, thereby avoiding parallel routing areas with RJ-45 and other port cables 20. By adjusting the inclination angle of the guide groove 12a, the physical distance between the cable 20 and interference sources can be maximized within the limited space inside the device, reducing the electromagnetic field coupling strength.

[0059] Through the above technical solution, this application effectively reduces the electromagnetic interference intensity between cable 20 and adjacent ports, reduces the parallel routing area by forming the avoidance space through the inclined transmission path, suppresses crosstalk of high-frequency signals between adjacent cables 20, and avoids the problem of increased cable 20 diameter caused by adding shielding layer, thus achieving a balance between signal integrity and space utilization efficiency in compact electronic devices.

[0060] Please see Figure 3 and Figure 4 This application further proposes that the groove opening of the guide groove 12a is elliptical.

[0061] In this embodiment, the slot of the guide groove 12a refers to the opening structure on the guide part 12 for the cable 20 to pass through. Specifically, it can be implemented as an elliptical structure with its major axis extending along the inclined transmission direction of the cable 20 and its minor axis perpendicular to the diameter direction of the cable 20. The major axis of the ellipse provides extended space for adjusting the tilt angle of the cable 20, while the minor axis constrains the lateral displacement of the cable 20. Here, the ellipse refers to a non-circular closed curve. This shape adapts to the bending deformation of the cable 20 through an asymmetrical structure, achieving the dual requirements of tilt angle adjustment and cable 20 protection within a limited space.

[0062] Specifically, during inclined transmission, the cable 20 undergoes cross-sectional deformation due to bending. The major axis of the elliptical slot aligns with the inclined extension direction of the cable 20, effectively accommodating the flattening deformation caused by bending. When the cable 20 passes through the guide slot 12a, its outer surface forms a contact constraint with the edge of the slot along its minor axis, thereby limiting the cable 20's offset in the non-inclined direction. Compared to a circular slot, the extended space along the major axis of the elliptical slot allows the cable 20 to exit at a greater inclination angle, while the dimensions along its minor axis match the diameter of the cable 20, preventing excessive compression and insulation wear during transmission.

[0063] Through the above technical solution, this application solves the problem of limited transmission angle of cable 20 caused by unreasonable shape design of guide groove 12a, so that cable 20 forms an effective avoidance space during inclined exit, while ensuring the stability of the transmission path of cable 20 and reducing the probability of coupling with electromagnetic interference from adjacent ports.

[0064] Please see Figure 3 and Figure 4 This application further proposes to provide a recess on the side of the outer mold 11 adjacent to the output surface 10b, the recess being used to accommodate the protruding portion of the device port.

[0065] In this embodiment, the recess refers to the groove structure formed inward on the surface of the outer mold 11, which can be achieved by stamping or injection molding. Its depth and shape are matched according to the size of the protruding part of the device port. This structure eliminates the spatial conflict between the connector 10 and the adjacent device port through physical avoidance.

[0066] The protruding portion of the device port refers to the outward extension of the mechanical structure on the device body, which can be a port protective cover, a fixing clip, or a dust plug. The spatial layout of the recessed portion complements and nests with the protruding portion. This design allows the connector 10 to avoid the space occupied by the original structure of the device port during installation.

[0067] Specifically, the recess is located on the edge region of the outer mold 11 adjacent to the output surface 10b, corresponding to the conventional mounting direction of the protruding part of the device port. When the connector 10 mates with the device, the recess completely encloses the protruding structure of the device port within its internal space, creating a non-interference physical contact between the outer mold 11 of the connector 10 and the device port. Through the geometric adaptation of the recess and the protruding part, the connector 10 can achieve compatible installation with adjacent device ports without changing its overall dimensions, making it particularly suitable for compact electronic devices with multiple ports arranged side-by-side.

[0068] Compared with existing technologies, traditional connector 10 outer mold 11 typically adopts a planar design. When there is a protruding structure at the device port, the connector 10 outer mold 11 may be squeezed or misaligned with the protruding part, resulting in incomplete insertion or poor contact. This solution, through the space reserved in the recessed part, allows the mechanical structure of the connector 10 to complement each other, maintaining the miniaturization of the connector 10 while avoiding assembly failure caused by spatial interference.

[0069] Please see Figure 2 and Figure 3 This application further proposes that the two plugs 10c are USB-C type.

[0070] In this embodiment, terminals of the same type refer to interface components with the same physical structure and electrical protocol. Specifically, they can be implemented using USB Type-C or RJ-45 standard interfaces, ensuring signal path consistency through a unified transmission protocol. Terminals of different types refer to interface components with differentiated physical structures and independent communication protocols. Specifically, they can be implemented using a combination of USB Type-C and RJ-45 interfaces, achieving signal transmission path separation through physical isolation.

[0071] Specifically, when the two plugs 10c are of the same type, the signal transmission path maintains a unified protocol standard, avoiding signal attenuation caused by interface conversion and eliminating the risk of electromagnetic coupling between different protocols. When different types of terminals are used, different signal transmission paths are spatially isolated at the physical layer, allowing high-speed data signals and Ethernet signals to be transmitted through independent channels, reducing electromagnetic interference between adjacent ports. This configurable mode allows the cable 20 to adapt to the standardized requirements of a single device interface within a limited space, while also meeting the signal isolation requirements in scenarios with multiple ports coexisting.

[0072] Through the above technical solution, this application can select the terminal configuration mode according to the actual equipment port layout, effectively reducing electromagnetic interference between different types of ports while maintaining the integrity of high-speed signals. When using terminals of the same type, signal conversion loss can be avoided and the interface matching process can be simplified; when using terminals of different types, signal coupling paths can be blocked by physical isolation, thereby achieving the coexistence and stable operation of multiple protocol ports in a limited space.

[0073] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
