Description

Technical Field

[0001] The present application relates to the field of cable technology, and in particular to a cable, a connector assembly, and an electronic device. Background Art

[0002] Cables usually include power cables and signal cables, which are used to connect circuit boards, communication equipment, etc. to complete the transmission of electrical energy or signals.

[0003] For signal cables, the larger the cable diameter, the smaller the signal transmission loss. Therefore, in order to meet the signal transmission loss requirements of some communication devices, the wire diameters of some cables are set to be larger.

[0004] However, in some communication scenarios, the communication devices connected by the cables have the need for multiple signal transmission channels, that is, multiple cables are needed to transmit multiple signals. When the space for laying out the cable interface of the communication device is limited, a smaller wire diameter is required to achieve more signal transmission channels. Therefore, the current cables cannot simultaneously meet the requirements of the communication devices for signal transmission loss and multiple signal transmission channels. Utility Model Content

[0005] In order to solve the above technical problems, the embodiments of the present application provide a cable, a connector assembly and an electronic device.

[0006] In a first aspect, an embodiment of the present application provides a cable comprising at least one conductor and an outer sheath wrapping the at least one conductor; the cable comprises a first section located at one end thereof and a second section connected to the first section, wherein the first section has a first wire diameter, the second section has a second wire diameter, the first wire diameter is greater than the second wire diameter, and the wire diameter of the conductor in the first section is greater than the wire diameter of the conductor in the second section.

[0007] Based on the above scheme, an embodiment of the present application provides a cable with variable wire diameter. For example, the wire diameter at one end of the cable along the length direction is larger than the wire diameter at the other end, or the wire diameter at the middle position of the cable is larger than the wire diameter at both ends. In this way, the wire diameter of at least one end of the cable is smaller, which can meet the needs of communication devices for multiple signal transmission channels in some communication scenarios, and the wire diameter at the other end or the middle position of the cable is larger, which can reduce signal transmission loss.

[0008] In some possible implementations of the first aspect above, the wire in the first section is welded to the wire in the second section.

[0009] It can be understood that the wire can be formed by welding different wire segments, and different wire segments can have different wire diameters.

[0010] In some possible implementations of the first aspect above, the end of the wire in the first section close to the second section has a first welding end, and the end of the wire in the second section close to the first section has a second welding end, and the first welding end and the second welding end are welded together; wherein the first welding end and the second welding end are flat, and the first welding end and the second welding end are overlapped along a first direction, and the first direction is perpendicular to the length direction of the cable.

[0011] It can be understood that the flat welding end has a larger welding surface, which can improve the stability of the welding and enhance the integrity of the signal transmission between the segmented wires.

[0012] In some possible implementations of the first aspect, the wires in the first section and the wires in the second section are integrally formed. For example, the wires in the first section and the wires in the second section are formed from the same wire. This ensures signal transmission integrity.

[0013] In some possible implementations of the first aspect above, the cable also includes a third section, and the first section and the second section are connected by the third section; the wire diameter of the third section gradually decreases from the first wire diameter to the second wire diameter from one end toward the first section to the end toward the second section, and the wire diameter of the wire in the third section gradually decreases from the wire diameter of the wire in the first section to the wire diameter of the wire in the second section.

[0014] In some possible implementations of the first aspect above, the cable further includes a fourth section located at the other end thereof, the fourth section having a fourth wire diameter, the fourth wire diameter being smaller than the first wire diameter, and the wire diameter of the conductor in the fourth section being smaller than the wire diameter of the conductor in the first section.

[0015] It can be understood that the wire diameters at both ends of the cable (the second and fourth sections) are smaller, and both can be used to connect communication devices with high-density output lines, and the wire diameter in the middle position (the first section) is larger, which can reduce the signal transmission loss between the two communication devices.

[0016] In some possible implementations of the first aspect above, the fourth wire diameter is equal to the second wire diameter.

[0017] It can be understood that in other possible implementations, the fourth wire diameter may be smaller or larger than the second wire diameter.

[0019] The first and second dielectric layers can both be formed of insulating materials. The first and second dielectric layers are used to ensure electrical isolation between the first and second conductors. The third dielectric layer can be the shielding layer mentioned in the embodiments of the present application and can be formed of a metal material to provide signal shielding.

[0020] In some possible implementations of the first aspect above, the first conductor includes a first conductor segment and a second conductor segment, the second conductor includes a third conductor segment and a fourth conductor segment, the first conductor segment and the third conductor segment correspond to the conductor in the first segment, and the second conductor segment and the fourth conductor segment correspond to the conductor in the second segment; the cable further includes: at least one insulating member, the at least one insulating member respectively wraps the first welding portion between the first conductor segment and the second conductor segment, and the second welding portion between the third conductor segment and the fourth conductor segment, a conductive member, the conductive member is wrapped in the at least one insulating member, and the conductive member is in contact with the third dielectric layer.

[0021] It is understood that the insulating member and the conductive member are located between the first and second sections. The insulating member can electrically isolate the first and second welding portions, preventing crosstalk between the signals transmitted by the two wires. The conductive member connects the third dielectric layer (shielding layer) of the first section with the third dielectric layer (shielding layer) of the second section to ensure that the entire wire is not interfered with by external signals.

[0022] In some possible implementations of the first aspect above, the conductive member includes any one of a conductive plastic member, a conductive adhesive, and a metal foil.

[0023] In some possible implementations of the first aspect above, at least one insulating part includes a first insulating injection-molded part, the first insulating injection-molded part includes an insulating wall, and the insulating wall is located between the first welding part and the second welding part; or, at least one insulating part includes two insulating sleeves, and the two insulating sleeves are respectively sleeved on the first welding part and the second welding part.

[0024] In some possible implementations of the first aspect above, multiple cables are arranged in parallel, at least one insulating part includes a second insulating injection-molded part, and the second insulating injection-molded part includes a plurality of insulating walls, wherein the plurality of insulating walls correspond one-to-one to the multiple cables, and each insulating wall is located between the first welding portion and the second welding portion in each cable.

[0025] It is understood that multiple cables can be arranged in parallel to form a cable group. During the manufacturing process, all cables in the cable group can be subjected to welding and injection molding processes at the same time.

[0026] In some possible implementations of the first aspect, the cable is any one of a ground-free cable, a single-ground-wire cable, and a double-ground-wire cable.

[0027] It is understood that a single-ground-wire cable includes not only the aforementioned conductors but also a ground wire.

DETAILED DESCRIPTION

[0052] Illustrative embodiments of the present application include, but are not limited to, a cable, a connector assembly, and an electronic device.

[0053] It should be noted that the cables of the present application include but are not limited to cables with no ground wire structure, cables with a single ground wire structure, and cables with a double ground wire structure. The embodiments of the present application only use cables with no ground wire structure as examples and do not constitute a limitation on the cable type.

[0054] As mentioned above, current cables cannot simultaneously meet the requirements of communication devices for signal transmission loss and multiple signal transmission channels. Figure 1A shows a schematic diagram of the three-dimensional structure of the cable 1a in some embodiments, Figure 1B It should be noted that the length direction of the cable mentioned in the embodiments of the present application can refer to the X direction shown in the various figures.

[0055] like Figure 1A As shown, the cable 1a includes two conductors 10 arranged side by side, and a dielectric layer 20, a dielectric layer 30, a shielding layer 40 and a protective layer 50 that wrap the conductors 10. Among them, the conductors 10 are used to transmit electrical signals, the dielectric layer 20 is directly wrapped around the outer layer of the conductor 10, and the dielectric layer 30 wraps the two dielectric layers 20 as a whole. The dielectric layers 20 and 30 are both made of dielectric materials to electrically isolate different conductors 10 from each other and ensure good insulation. The shielding layer 40 is wrapped around the outer layer of the dielectric layer 30. The shielding layer 40 can be made of metal materials (such as aluminum foil, copper foil) to prevent electromagnetic interference to ensure the integrity of the electrical signal transmitted through the conductor 10. The protective layer 50 is located at the outermost layer of the cable 1a and can be made of insulating material (such as Mylar) to protect the inner layer from the intrusion of external impurities and moisture, and to protect the inner layer from damage by external forces. In some embodiments, the cable 1a may also not include the dielectric layer 30.

[0056] The wire diameter of a cable can be the outer diameter of the cable cross section in any direction. Figure 1B As shown, in some embodiments, the wire diameter of the cable 1a may be dimension Y1 in the Y direction. In other embodiments, the wire diameter of the cable 1a may be dimension Z1 in the Z direction. The Y direction may refer to the direction in which the two conductors 10 are arranged side by side, and the Z direction, the Y direction, and the X direction are perpendicular to each other.

[0057] It can be understood that under the current manufacturing process, the entire cable 1a uses wires 10, dielectric materials, metal materials, and insulating materials of the same size and specifications, and is rolled and continuously processed into shape. Therefore, the wire diameter of the entire cable 1a is relatively uniform and unified along its length.

[0058] Since the larger the wire diameter of cable 1a, that is, the thicker the cable 1a, the smaller the loss generated when the current passes through, the smaller the signal transmission loss, and the higher the transmission efficiency. Therefore, in order to meet the requirements of communication devices for signal transmission loss, the wire diameter dimensions Y1 / Z1 of cable 1a are both set to be larger.

[0059] However, in some communication scenarios, the communication devices connected to cable 1a have limited dimensions for cable interface layout. Furthermore, as the types of signals transmitted by these devices increase, they need to connect more cables 1a within this limited dimension to achieve multiple signal transmission channels. This requires cable 1a to have a smaller diameter as possible. As previously mentioned, signal transmission loss requires cable 1a to have a larger diameter as possible. Therefore, the signal transmission loss and multiple signal transmission channels conflict with the cable 1a diameter requirements. Currently, cable 1a cannot simultaneously meet the signal transmission loss and multiple signal transmission channel requirements of some communication devices.

[0060] Based on this, an embodiment of the present application provides a cable, wherein the cable diameter is variable along its length, for example, Figure 2 In one embodiment of the present application, the diameter Y3 of the cable 1 at one end along the length direction (Y direction) is larger than the diameter Y2 of the other end, or, Figure 3 In another embodiment of the present application, the wire diameter Y5 in the middle position of the cable 1 is larger than the wire diameter Y4 / Y6 at both ends. In this way, the wire diameter of at least one end of the cable 1 is smaller, which can meet the needs of communication devices for multiple signal transmission channels in some communication scenarios. In addition, the wire diameter at the other end or the middle of the cable 1 is larger, which can reduce signal transmission loss.

[0061] For example, Figure 4 A communication scenario is shown, including a communication device 01 and a communication device 02, which are connected via multiple cables 1. The cable interface size of communication device 01 is smaller than that of communication device 02. In other words, the number of signal transmission channels between communication device 01 and the multiple cables 1 is greater than the number of signal transmission channels between communication device 02 and the multiple cables 1.

[0062] Among them, the wire diameter of one end of the cable 1 is larger than the wire diameter of the other end. Therefore, the cable 1 is connected to the communication device 01 through the end with a smaller wire diameter, which can ensure that all signal transmission channels in the communication device 01 can be laid out. At the same time, the cable 1 is connected to the communication device 02 through the end with a larger wire diameter, which can ensure that the signal transmission loss output by the communication device 02 is low. Therefore, the cable 1 of the embodiment of the present application can meet the requirements of different communication devices for signal transmission loss and multiple signal transmission channels in the same communication scenario.

[0063] The specific structure of the cable 1 in some embodiments of the present application is described below with reference to the accompanying drawings.

[0064] Figure 5 The structure diagram of the first cable 1 according to the embodiment of the present application is shown. Figure 5 As shown, the cable 1 includes at least one conductor 10 and an outer covering layer wrapping the at least one conductor 10 .

[0065] It should be noted that the embodiment of the present application takes the cable 1 as an example, which includes two conductors 10 (the first conductor and the second conductor of the present application) arranged side by side along the Y direction, and the two conductors 10 have the same structure and size, for example, the wire diameter in the Y direction is the same, and the two conductors 10 only have different uses, for example, for transmitting different signals. The outer surrounding layer includes a first dielectric layer that wraps the first conductor, a second dielectric layer that wraps the second conductor, and a third dielectric layer that wraps the first dielectric layer and the second dielectric layer. Here, in combination with Figure 1A and Figure 1B In the structure of the cable 1a shown, the first and second dielectric layers may be referred to as dielectric layer 20, and the third dielectric layer may be referred to as shielding layer 40. In some embodiments, the outer envelope layer may further include a dielectric layer 30 and a protective layer 50. The materials and functions of each layer are described in the above embodiments and will not be further elaborated.

[0066] Along the Y direction, the cable 1 includes a first segment 1-1 at one end thereof and a second segment 1-2 connected to the first segment 1-1. The first segment 1-1 has a first wire diameter Y7 in the Y direction, and the second segment 1-2 has a second wire diameter Y8 in the Y direction. The first wire diameter Y7 is larger than the second wire diameter Y8. Furthermore, the wire diameter of the conductor 10 in the first segment 1-1 in the Y direction is larger than the wire diameter of the conductor 10 in the second segment 1-2 in the Y direction.

[0067] It should be noted that the diameters of the cables 1 or wires 10 mentioned in the various embodiments of the present application are all based on the diameters in the Y direction. In other embodiments of the present application, the diameters of the cables 1 or wires 10 may also refer to the diameters in the Z direction.

[0068] The cable 1 provided in an embodiment of the present application has a first section 1-1 and a second section 1-2 with different wire diameters. When connecting communication devices through the cable 1, the first section 1-1 with a thinner wire diameter can be used to connect communication devices with high-density output lines (for example, communication devices with multiple signal transmission channels), and the second section 1-2 with a thicker wire diameter can be used to connect communication devices that output high-speed signals. In this way, the cable 1 can meet the requirements of different communication devices for signal transmission loss and multiple signal transmission channels in the same communication scenario, and can reduce the signal transmission loss between the two communication devices.

[0069] In some embodiments, the conductors 10 in the cable 1 are segmented conductors. Specifically, the conductors 10 may be formed by welding different conductor segments, and the different conductor segments may have different wire diameters. For example, for any of the two conductors 10, the conductor 10 in the first segment 1-1 is a first conductor segment, and the conductor 10 in the second segment 1-2 is a second conductor segment. The first conductor segment and the second conductor segment are welded together.

[0070] For example, Figure 6 Shown Figure 5 The internal structure diagram of the dotted box A. Figure 6 As shown, the first of the two wires 10 includes a first wire segment 10a-1 and a second wire segment 10a-2. The wire diameter of the first wire segment 10a-1 is larger than the wire diameter of the second wire segment 10a-2, and the first wire segment 10a-1 and the second wire segment 10a-2 are welded to each other. The second of the two wires 10 includes a third wire segment 10b-1 and a fourth wire segment 10b-2. The wire diameter of the third wire segment 10b-1 is larger than the wire diameter of the fourth wire segment 10b-2, and the third wire segment 10b-1 and the fourth wire segment 10b-2 are welded to each other.

[0071] The first and third wire segments 10a-1 and 10b-1 are located in the first segment 1-1, and the wire diameter of the first and third wire segments 10a-1 are the same. The second and fourth wire segments 10a-2 and 10b-2 are located in the second segment 1-2, and the wire diameter of the second and fourth wire segments 10a-2 are the same.

[0072] In some embodiments, each of the above-mentioned wire segments has a welding end, and the welding end is flat. Figure 6 In the enlarged partial view, the first wire segment 10a-1 has a soldering end 10a1 at its end near the second segment 1-2, and the third wire segment 10b-1 has a soldering end 10b1 at its end near the second segment 1-2. These soldering ends 10a1 / 10b1 are flat, for example, with soldering surfaces parallel to the XY plane. It is understood that the second wire segment 10a-2 and the fourth wire segment 10b-2 both have similar structures to the soldering ends 10a1 / 10b1. Thus, the soldering surface of soldering end 10a1 overlaps the soldering surface of the second wire segment 10a-2 along the Z direction, and the soldering surface of soldering end 10b1 overlaps the soldering surface of the fourth wire segment 10b-2 along the Z direction. It is understood that the larger soldering surface of the flat soldering end improves soldering stability and enhances the integrity of signal transmission between the wire segments.

[0073] In some embodiments, the cable 1 further includes an insulating member and a conductive member, and the insulating member and the conductive member are located between the first section 1-1 and the second section 102. For example, Figure 7 As shown, the insulating member includes an insulating injection molded part 61 (an example of the first insulating injection molded part of the present application). Insulating injection molded part 61 respectively surrounds the first weld between the first wire segment 10a-1 and the second wire segment 10a-2, and the second weld between the third wire segment 10b-1 and the fourth wire segment 10b-2. The first weld includes the weld end 10a1 of the first wire segment 10a-1 and the weld end of the second wire segment 10a-2, and the second weld includes the weld end 10b1 of the third wire segment 10b-1 and the weld end of the fourth wire segment 10b-2. The dimensions of insulating injection molded part 61 along the X direction exceed the dimensions of the weld / weld end along the X direction, and the dimensions of insulating injection molded part 61 along the Z direction or the Y direction exceed the dimensions of the second segment 1-2 along the Z direction or the Y direction. Insulating injection molded part 61 includes an insulating wall located between the first weld and the second weld. The insulating wall is used to electrically isolate the first weld from the second weld to prevent crosstalk between the signals transmitted by the two wires.

[0074] In some embodiments, as Figure 8 As shown, the insulating member further includes an insulating injection molded part 62, which is embedded in the insulating injection molded part 61 to seal the opening on the insulating plastic part 61. In some embodiments, the insulating injection molded part 61 and the insulating injection molded part 62 can be an integrated structure. The integrated insulating injection molded part 61 and the insulating injection molded part 62 can be the first insulating injection molded part mentioned in this application.

[0075] In other embodiments, the insulating member may also include two insulating sleeves (such as heat shrink tubes), which are respectively sleeved on the first welding part and the second welding part to isolate the electrical connection between the first welding part and the second welding part to avoid crosstalk between the signals transmitted by the two wires 10.

[0076] In some embodiments, combined Figure 5 and Figure 8 As shown, the conductive member includes a conductive plastic member 71, which is wrapped around the outer layer of the insulating member (e.g., the insulating injection molded member 61 and the insulating injection molded member 62) and contacts the third dielectric layer (shielding layer 40). In other embodiments, the conductive member may include conductive glue or metal foil. The conductive member is used to connect the shielding layer 40 of the first segment 1-1 and the shielding layer 40 of the second segment 1-2 to ensure that the entire wire 10 is not interfered with by external signals.

[0077] In addition, the present invention provides a Figure 5 The manufacturing process of the cable 1 is shown. Figure 9It shows a schematic diagram of the structure of the cable 1 under various manufacturing processes, combined with Figure 9 As shown, the manufacturing process of the cable 1 includes the following steps:

[0078] S11: Stripping the cables 100 and 200 of different wire diameters to expose the wires of the cables 100 and 200, and flattening the wires.

[0079] Reference Figure 9 As shown in (a) and (b) in FIG. 1 , two cables 100 and 200 with different wire diameters are obtained. It can be understood that the cables 100 and 200 have the same Figure 1A 、 Figure 1B The cable 1a shown has a similar layer structure. Cables 100 and 200 are then peeled off layer by layer to expose the two wires 10 and a portion of the shielding layer 40 inside. The two wires 10 are then flattened to form the flat structure described above, facilitating subsequent soldering steps.

[0080] S12: welding the wires of the cable 100 and the wires of the cable 200 using a welding process (such as resistance welding, laser welding, or hot pressing welding).

[0081] Reference Figure 9 In (c), the two wires 10 in the cable 100 and the cable 200 are welded respectively, so that the wires in the cable 100 and the wires in the cable 200 form a whole wire, that is, the segmented wire mentioned above. The wire in the cable 100 can be the first wire segment / the third wire segment, and the wire in the cable 200 can be the second wire segment / the fourth wire segment.

[0082] S13: forming an insulating injection molded part 61 through an injection molding process.

[0083] Reference Figure 9 In (d), an insulating injection molded part 61 is formed by injection molding at the welding connection between the cable 100 and the cable 200 to protect the welding point on the wire 10, and the structure of the insulating injection molded part 61 can ensure electrical insulation between the two wires 10.

[0084] S14: forming an insulating injection molded part 62 through an injection molding process.

[0085] Reference Figure 9 In (e), an insulating injection molded part 62 is formed by injection molding on the periphery of the insulating injection molded part 61 to seal the openings (such as supporting holes and other process holes) on the insulating injection molded part 61.

[0086] S15: forming a conductive plastic part 71 through an injection molding process.

[0087] Reference Figure 9In step (f), a conductive plastic part 71 is formed on the outer sides of the insulating injection molded parts 61 and 62 by injection molding to connect the shielding layers 40 of the cables 100 and 200 to ensure a good shielding effect.

[0088] Figure 10 The structure of the second cable 1 provided in the embodiment of the present application is shown. Figure 5 The difference between the structures shown is that the structures of the first section 1-1 and the second section 1-2 of the cable 1 are different, for example, the structures of the insulating member and the conductive member at the position shown by the dotted box B are different.

[0089] Figure 11 、 12 Shown Figure 10 The internal structure diagram of the dotted box B is shown in the figure. Figure 11 As shown, the insulating member of the cable 1 includes an insulating member 63, which has the same function as the insulating injection molded member 61 described above, but has different dimensions and structures. For example, the dimension of the insulating member 63 along the X direction is the same as the dimension of the welding portion / welding end of the wire along the X direction, and the dimension along the Z direction or the Y direction does not exceed the dimension of the second segment 1-2 along the Z direction or the Y direction. Figure 12 As shown, the conductive member of the cable 1 includes a metal foil 72. The size of the metal foil 72 along the X direction is larger than the size of the insulating member 63 along the X direction. The metal foil 72 is in contact with the shielding layer 40 of the first section 1-1 and the second section 1-2 respectively. The metal foil 72 can specifically include copper foil or aluminum foil.

[0090] Continue reading Figure 10 The cable 1 may further include a heat shrink tube 80 located on the outer layer of the metal foil 72 , wherein the size of the heat shrink tube 80 along the X direction is larger than the size of the metal foil 72 along the X direction. The heat shrink tube 80 is used to protect the inner metal foil 72 and the insulating member 63 .

[0091] In addition, the present invention provides a Figure 10 The manufacturing process of the cable 1 is shown. Figure 13 It shows a schematic diagram of the structure of the cable 1 under various manufacturing processes, combined with Figure 13 As shown, the manufacturing process of the cable 1 includes the following steps:

[0092] S21: Stripping the cables 100 and 200 of different wire diameters to expose the wires of the cables 100 and 200, and flattening the wires.

[0093] S22: welding the wires of the cable 100 and the wires of the cable 200 using a welding process (such as resistance welding, laser welding, or hot pressure welding).

[0094] Understandable, refer to Figure 13In (a) to (c), steps S21 and S22 are the same as S11 and S12 described above. For details, please refer to the description of the above embodiment and will not be repeated here.

[0095] S23: forming the insulating member 63 by injection molding or wrapping process.

[0096] Reference Figure 13 In (d), an insulating member 63 is formed at the welding connection between the cable 100 and the cable 200 by injection molding or wrapping process, which can protect the welding point on the wire 10, and the structure of the insulating member 63 can ensure electrical insulation between the two wires 10.

[0097] S24: forming the metal foil 72 by wrapping or longitudinal wrapping.

[0098] Reference Figure 13 In (e), a metal foil 72 is formed on the outer periphery of the insulating member 63 by a wrapping or longitudinal wrapping process to connect the shielding layers 40 of the cables 100 and 200 to ensure a good shielding effect.

[0099] S25: Wrap with heat shrink tube 80.

[0100] Reference Figure 13 In (f), by sheathing the heat shrink tube 80 on the outside of the metal foil 72, the solder joints of the wire 10, the internal shielding layer 40 and other structures can be better protected.

[0101] Figure 14 A schematic structural diagram of a third cable 1 provided in an embodiment of the present application is shown. Figure 14 The cable 1 shown is Figure 5 The difference in the structure of the cable 1 is that the conductors 10 in the first section 1-1 and the conductors 10 in the second section 1-2 are integrally formed. For example, the conductors 10 in the first section 1-1 and the conductors 10 in the second section 1-2 are formed from the same conductor 10.

[0102] Figure 15 Shows a Figure 14 Schematic diagram of the cross section of the cable 1 is shown. Figure 14 and Figure 15 As shown, cable 1 also includes a third section 1-3 located between first section 1-1 and second section 1-2, connecting first section 1-1 and second section 1-2 via third section 1-3. Furthermore, each conductor 10 is wrapped with a dielectric layer 20, which is then wrapped with a shielding layer 40 or a protective layer 50. It will be appreciated that in this embodiment, cable 1 can be a complete cable with two sections of varying thicknesses, produced by varying the diameter of the conductors 10, the outer sheath diameter, and the dimensions.

[0103] Combine Figure 14 and Figure 15 As shown, the wire diameter of the third section 1-3 gradually decreases from the first wire diameter to the second wire diameter along the X direction from one end toward the first section 1-1 to one end toward the second section 1-2. Figure 15 As shown, the wire diameter of the cable 1 decreases from the wire diameter Y7 of the first section 1-1 to the wire diameter Y8 of the second section 1-2, and the wire diameter of the conductor 10 in the third section 1-3 gradually decreases from the wire diameter of the conductor 10 in the first section 1-1 to the wire diameter of the conductor 10 in the second section 1-2.

[0104] It can be understood that in this embodiment, the first section 1-1 and the second section 1-2 can have a fixed wire diameter, and the third section 1-3 can have a variable wire diameter. Figure 15 As shown, in the third section 1-3, the wire 10 first gradually decreases in diameter from Y7 to Y8, and then maintains the wire diameter Y8 unchanged.

[0105] Above Figures 5 to 15 In the cable 1 of the related embodiment, along the X direction, the wire diameter of one end of the cable 1 is larger than the wire diameter of the other end. Figure 3 As shown, along the X direction, the wire diameters of the cable 1 at both ends are smaller than the wire diameter at the middle position.

[0106] For example, in Figure 5 or Figure 10 or Figure 14 In addition to the illustrated structure, the cable 1 may further include a fourth segment connected to the first segment 1-1. The fourth segment and the second segment 1-2 are located on opposite sides of the first segment 1-1 along the X direction. The fourth segment has a fourth wire diameter that is smaller than the wire diameter Y7. Furthermore, the wire diameter of the conductor 10 in the fourth segment is smaller than the wire diameter of the conductor 10 in the first segment 1-1.

[0107] In some embodiments, the fourth wire diameter can be the same as the wire diameter Y8 of the second segment 1-2. In this way, in some communication scenarios, since the wire diameters at both ends of the cable 1 (the second and fourth segments) are smaller, both can be used to connect to communication devices with high-density outgoing lines, and the wire diameter in the middle (the first segment) is larger, which can reduce signal transmission loss between the two communication devices.

[0108] Alternatively, in other embodiments of the present application, the cable 1 may have more connecting segments (including the first, second, and fourth segments described above) along the X direction, with two adjacent connecting ends having different wire diameters, and the connecting segments are not limited to including the first, second, and fourth segments described above. It should be noted that the present application does not limit the number of connecting segments of the cable 1.

[0109] For example, Figure 16 The structure diagram of the fourth cable 1 according to the embodiment of the present application is shown in FIG. Figure 16As shown, along the X direction, the cable 1 includes N connecting segments ( Figure 16 In the example, 5 connecting segments are used: the first segment 1-1, the second segment 1-2, the fourth segment 1-4, the fifth segment 1-5 and the sixth segment 1-6. The connection method between two adjacent connecting segments can refer to Figure 5 or Figure 10 or Figure 14 The connection method between the first section 1-1 and the second section 1-2.

[0110] Above Figures 5 to 15 The cable 1 in the relevant embodiment is a single structure. In some embodiments, multiple cables 1 can be arranged in parallel to form a cable group. Therefore, it should be noted that the cable described in this application can refer to a single cable or a cable group formed by combining multiple cables.

[0111] Figure 17 FIG. 1 shows a schematic structural diagram of a first cable assembly 100 according to an embodiment of the present application. Figure 17 As shown, the cable set 100 includes more than two cables 1, where Figure 17 In the figure, two cables 1 are arranged side by side to form a cable group 100 as an example. The insulating parts (second insulating injection-molded parts) of the two or more cables 1 are an integrated structure, and the conductive parts are also an integrated structure. In addition, although not shown in the figure, the insulating parts include a plurality of insulating walls, and the plurality of insulating walls correspond one-to-one to the two or more cables 1. That is, each insulating wall is located between the first welding portion and the second welding portion of the two wires 10 in each cable 1. The conductive part is exemplified by the conductive plastic part 73. It can be understood that during the manufacturing process, all cables 1 in the cable group 100 can undergo welding and injection molding processes simultaneously.

[0112] Figure 18 1 is a schematic structural diagram of the second cable assembly 100 according to an embodiment of the present application. Figure 18 As shown, the cable set 100 includes more than two cables 1, where Figure 18 In the example, four cables 1 are arranged in parallel to form a cable assembly 100. The insulating components of the two or more cables 1 are integrated, and the conductive components are also integrated. Here, the conductive components are exemplified by conductive sheet 74, which is welded or clamped to the four cables 1.

[0113] In addition, an embodiment of the present application further provides a connector assembly, which includes any cable 1 of the embodiment of the present application and two connectors, which are respectively arranged at both ends of the cable 1 along the X direction for connecting to a communication device.

[0114] After testing in actual applications, using the thinner wire end of Cable 1 at one connector end to achieve high-density cable output, and using the thicker wire end of Cable 1 at the other connector end to reduce loss. Under the specification of Cable 1 being 1.5 meters long, the loss can be reduced by 4dB / line compared to using the thinner wire end of the cable at both connector ends.

[0115] Furthermore, in some embodiments, considering that the loss of cable 1 is related to the dielectric loss factor (Df) and dielectric constant (Dk) of the dielectric material of dielectric layer 20 / 30, the lower the dielectric loss, the lower the loss of cable 1. Therefore, by reducing the dielectric loss factor (Df) and dielectric constant (Dk) of the dielectric material of dielectric layer 20 / 30, the transmission loss of cable 1 can be further reduced. For example, using a foamed dielectric layer can reduce dielectric loss, thereby further helping to reduce the wire diameter of the cable.

[0116] In some embodiments, considering that the loss of cable 1 is also related to the conductivity of wire 10, the higher the conductivity, the smaller the loss of cable 1. Therefore, in addition to silver-plated copper wire, wire 10 can also be graphene copper wire.

[0117] In addition, an embodiment of the present application further provides an electronic device comprising a cable according to any of the above embodiments and an electronic device, wherein the electronic device is electrically connected to the cable, and the electronic device can transmit signals to other electronic devices via the cable. Exemplary electronic devices include, but are not limited to, chips and circuit boards.

[0118] The electronic devices of the embodiments of the present application include, but are not limited to, mobile stations (MS), mobile terminals (MT), etc. For example, the electronic devices may be mobile phones, smart TVs, wearable devices, tablet computers (Pads), desktop computers, laptop computers, virtual reality (VR) devices, augmented reality (AR) devices, terminals in industrial control, terminals in self-driving, terminals in remote medical surgery, terminals in smart grids, terminals in transportation safety, terminals in smart cities, terminals in smart homes, etc. The embodiments of the present application do not limit the specific form of the electronic devices.
