[0049] In the modern vehicle industry, with the progress of technology and the widespread application of electronic equipment, the electrical system of vehicles becomes increasingly complex. A large number of sensors, control units and communication equipment are included in vehicles, and the normal operation of these components is crucial to the performance, safety and comfort of vehicles.

[0050] Shielded wire is a kind of cable with special structure, which is covered with conductive material on the outside to form a shielding layer. The main function of this shielding layer is to prevent electromagnetic interference and radio frequency interference from affecting signal transmission. In vehicles, electromagnetic interference may come from the engine, wireless communication equipment, and even other electronic components. These interferences can cause signal distortion, which in turn affects the performance of the vehicle.

[0051] Shielded wire plays an indispensable role in modern vehicles. The use of shielded wire can improve signal integrity, reduce noise interference, and enhance safety.

[0052] In the related art, after cutting the shielded wire, the shielding layer is exposed, a support is sleeved outside the shielded wire, the shielding layer is disassembled and trimmed, and then the shielding layer is folded to cover the support, a crimping tube is sleeved outside the support covered with the shielding layer, and the crimping tube is punched into a specific shape to form fixation. In order to facilitate the connection of the shielded wire into the circuit.

[0053] However, in the related art, when the above operation is performed, the manufacturing process is complex, the processing difficulty is large, and the position accuracy is poor, resulting in material waste, high labor cost, and an increase in the number of defective products.

[0054] As shown in Figure 1 , a cross-sectional view of a connection wire is provided for an embodiment of the present application. Figure 1

[0055] To solve the above technical problems, the present application provides a connection wire 100, which comprises a shielded wire 1 and a shielding connector 2, wherein the shielded wire 1 comprises a wire 11 and a shielding layer 12, and the wire 11 is used for transmitting signals or currents.

[0056] The wire 11 can be bare metal or plated metal, can be single-core or multi-core, and can also be of various specifications.

[0057] The shielding layer 12 is annularly arranged outside the wire 11, and the shielding connector 2 is arranged outside the shielded wire 1. The shielding connector 2 and the shielding layer 12 are an integral structure, and the shielding connector 2 is electrically connected to the shielding layer 12.

[0058] In a possible implementation, the shielding connector is injection molded by conductive plastic and has conductive ability.

[0059] In this way, by setting the shielding connector 2 and the shielding layer 12 as an integral structure, the steps of punching, sleeving, and crimping the support and the crimping tube, and disassembling, trimming, and folding the shielding layer of the shielded wire are omitted, so that the processing difficulty is reduced, the manufacturing process is simple, the material waste and labor cost are reduced, and the defective rate can be effectively reduced.

[0060] At the same time, the process of folding the shielding layer 12 in the related art is no longer needed, the distance from the shielding connector 2 to the connection end of the wire 11 can be shortened, and thus the space occupied by the connection of the connection wire 100 to the connection end can be reduced.

[0061] For example, the shielding connector 2 is made by injection molding process. Specifically, the shielding connector 2 is injection molded outside the shielding layer 12, so as to connect the shielding connector 2 and the shielding layer 12 together. The shielding connector 2 formed by injection molding can improve the production efficiency. Moreover, the shielding connector 2 formed by injection molding has high precision, which can realize stable connection of the shielding layer 12 and ensure high surface finish and dimensional accuracy.

[0062] ​The shielding joint 2 is produced by injection molding, which has high adaptability and high automation degree, can complete large-scale production with less manpower, and improves production efficiency.

[0063] It should be noted that the thickness of the shielding layer 12 can be adjusted according to the current size and shielding requirements.

[0064] Before the embodiments of the present application are described in detail, the application scenario of the embodiments of the present application is first introduced.

[0065] In a possible implementation, the shielding joint 2 is a conductive plastic joint.

[0066] Continuing to refer to Figure 1 , the conductive plastic is a kind of composite material that has good processability and conductivity of plastic, and the shielding joint 2 is formed by injection molding of conductive plastic. The conductive plastic joint has the characteristics of lightweight, corrosion resistance, and strong processability.

[0067] In a possible implementation, the first end 111 is one end along the extension direction of the shielding wire 1, and the shielding wire 1 further includes a first insulating layer 13, which is arranged between the wire 11 and the shielding layer 12. The first insulating layer 13 provides insulation for the wire 11.

[0068] In the axial direction of the wire 11, the distance between the first insulating layer 13 and the first end 111 is less than the distance between the shielding layer 12 and the first end 111, and the distance between the first insulating layer 13 and the first end 111 is less than the distance between the shielding joint 2 and the first end 111. At least part of the first insulating layer 13 is an integral structure with the shielding joint 2.

[0069] The distance between the first insulating layer 13 and the first end 111 is less than the distance between the shielding layer 12 and the first end 111, and the distance between the first insulating layer 13 and the first end 111 is less than the distance between the shielding joint 2 and the first end 111. It can be understood that the length of the first insulating layer 13 is greater than the length of the shielding layer 12, and at least part of the first insulating layer 13 is an integral structure with the shielding joint 2, which can make the connection of the shielding joint 2 more stable.

[0070] At least part of the first insulating layer 13 is an integral structure with the shielding joint 2, which provides higher mechanical strength and structural stability. This integrated design makes the shielding joint 2 not easily affected by external forces during use, reducing signal problems caused by loosening of the shielding joint 2.

[0071] In addition, the shielding joint 2 is an integral structure with the shielding layer 12 and the first insulating layer 13 at the same time, which does not need additional processing of the shielding layer 12, improves production efficiency, and reduces cost.

[0072] Meanwhile, the shielding layer 12 is cut inside the shielding joint 2 formed by injection molding, thereby enhancing the aesthetic appearance.

[0073] With reference to the foregoing description Figure 1 In one possible implementation, the shielded wire 1 further comprises a second insulation layer 14, which is arranged on the side of the shielding layer 12 away from the wire 11.

[0074] The second insulation layer 14 provides insulation for the shielded wire 1 from the outside, and in particular in high-temperature, humid or corrosive environments, the second insulation layer 14 can effectively prevent the shielded wire 1 from being damaged by the outside environment, thereby prolonging the service life of the shielded wire 1.

[0075] For example, the second insulation layer 14 has excellent electrical insulation properties, which can effectively reduce the risk of electric leakage and improve the safety of the shielded wire 1.

[0076] In the axial direction of the wire 11, the distance between the second insulation layer 14 and the first end 111 is greater than the distance between the shielding layer 12 and the first end 111, and the distance between the second insulation layer 14 and the first end 111 is less than the distance between the side of the shielding joint 2 away from the first end 111 and the first end 111. At least part of the second insulation layer 14 is an integral structure with the shielding joint 2.

[0077] The distance between the second insulation layer 14 and the first end 111 is greater than the distance between the shielding layer 12 and the first end 111. It can be understood that the length of the shielding layer 12 is greater than the length of the second insulation layer 14, and at least part of the second insulation layer 14 is an integral structure with the shielding joint 2, which can make the connection of the shielding joint 2 more stable.

[0078] Meanwhile, the second insulation layer 14 and the shielding joint 2 form an integral structure, which can effectively reduce the stress concentration at the joint and enhance the overall mechanical strength and durability.

[0079] Through the above-mentioned arrangement of the first insulation layer 13 and the second insulation layer 14, the insulation joint wraps the shielding layer 12, reduces the damage risk caused by the exposure of the shielding layer 12, and provides better structural stability.

[0080] In one possible implementation, the shielding layer 12 is a metal mesh or a metal foil.

[0081] In one possible implementation, the shielding layer 12 is a conductive plastic layer. The shielding layer 12 can be directly formed by an extruder, without the need for weaving a metal mesh. Thus, the process for producing the shielding layer 12 is simple, metal resources can be saved, and costs can be reduced.

[0082] It should be noted that in the case where the first insulation layer 13 and the second insulation layer 14 are arranged, the shielded wire 1 is injection molded to form the shielding joint 2.

[0083] like Figure 2 As shown, Figure 2 This is an assembly diagram of a connecting wire 100 provided in an embodiment of the present application. In the first step, the shielded wire 1 is cut and stripped to remove the conductor 11, the first insulating layer 13, and the shielding layer 12.

[0084] like Figure 3 As shown, Figure 3 This is the second step of the assembly diagram of the connecting cable 100 provided in one embodiment of the present application; in the second step, a shielding connector 2 is injection-molded around the outside of the shielded wire 1 using a conductive plastic. It should be noted that before injection-molding the shielding connector 2 around the outside of the shielded wire 1, the first seal 7 can be placed over the shielded wire 1 to facilitate its use in subsequent processes.

[0085] like Figure 4 As shown, Figure 4 The third step is to use the terminal 3 to connect to the first end 111 (see Figure 1 ) is fixed to the shielded wire 1. In the second step, when the first seal 7 is installed, the first seal 7 can be placed close to the shielded connector 2 (see Figure 1 ).

[0086] like Figure 5 As shown, Figure 5 For this application Figure 1 A schematic structural diagram of the shielding connector 2 is provided in FIG.

[0087] Combine Figure 1 and Figure 5 As shown, in a possible embodiment, the shielding connector 2 includes a main body 21, the main body 21 includes a contact portion 211 and an enlarged portion 212 connected to the contact portion 211, the enlarged portion 212 is arranged on the side of the contact portion 211 away from the first end 111, and the distance between the enlarged portion 212 and the wall of the shielded wire 1 away from the shielded wire 1 is greater than the distance between the contact portion 211 and the wall of the shielded wire 1 away from the shielded wire 1.

[0088] The configuration of the enlarged portion 212 and the contact portion 211 helps to improve mechanical stability.

[0089] In one possible embodiment, the shielding connector 2 only includes the contact portion 211, and the expansion portion 212 is not provided. While ensuring smooth signal transmission, it can reduce the burden on the shielded wire 1 and the material usage of the shielding connector 2, saving materials and reducing waste.

[0090] Figure 6 A schematic structural diagram of a wiring harness 200 provided in one embodiment of the present application. Figure 7 For this applicationFigure 6 A cross-sectional view of the shielding shell 4.

[0091] In combination Figure 1 , Figure 5 , Figure 6 and Figure 7 , the application also provides a wire harness 200, which comprises the connecting wire 100 and the shielding shell 4, the shielding shell 4 is provided with the terminal through hole 41 and a plurality of bending parts 42, the shielding connector 2 is arranged in the terminal through hole 41, and the shielding connector 2 is connected with the plurality of convex bending parts 42.

[0092] In a possible implementation, the bending part 42 is elastic, and the bending part 42 is elastically connected with the connecting wire 100.

[0093] The shielding shell 4 can effectively prevent external electromagnetic waves from interfering with the signal, thereby ensuring the integrity and transmission quality of the signal.

[0094] In a possible implementation, a plurality of convex bending parts 42 are arranged around the terminal through hole 41, the bending parts 42 are used to connect with the shielding connector 2, form a grounding current loop of the shielding shell 4, and the plurality of bending parts 42 are connected with the shielding connector 2, which can improve the stability of the electrical connection.

[0095] There is a possible scenario that the connecting wire 100 is disconnected from the shielding shell 4 after being moved or shaken during use, resulting in the shielding shell 4 losing its function. The wire harness 200 is provided with a plurality of bending parts 42 during use, so that when the connecting wire 100 is displaced or shaken, there is always a bending part 42 in contact with the shielding connector 2, thereby improving the stability of the connection between the shielding connector 2 and the shielding shell 4.

[0096] The bending part 42 is an elastic component, when the shielding connector 2 is inserted into the terminal through hole 41, the bending part is deformed and compressed, and when the shielding connector 2 is installed in place, the bending part clamps the shielding connector 2 under the action of the restoring force, thereby realizing stable electrical connection between the shielding shell 4 and the shielding connector 2.

[0097] In a possible implementation, the shielding connector 2 comprises a guide surface 22, which connects the wall surface of the contact part 211 away from the shielding wire 1 and the end wall of the contact part 211 facing the first end 111.

[0098] The arrangement of the guide surface 22 makes the shielding connector 2 have a guiding effect when it is inserted into the shielding shell 4, facilitating the insertion of the shielding connector 2.

[0099] For example, the guide surface 22 can be an inclined surface or an arc surface.

[0100] In a possible implementation, the shielding connector 2 includes a blocking portion 23, the blocking portion 23 is located on the side of the main body portion 21 away from the first end 111, and the blocking portion 23 is connected with the main body portion 21, and the distance between the blocking portion 23 and the wall surface of the shielding wire 1 away from the shielding wire 1 is greater than the distance between the main body portion 21 and the wall surface of the shielding wire 1 away from the shielding wire 1.

[0101] The blocking portion 23 forms a flat end surface to block the first sealing member 7, and the blocking portion 23 can improve the blocking effect of the first sealing member 7.

[0102] In a possible implementation, the connecting wire 100 includes a first sealing member 7, the first sealing member 7 is arranged on the side of the blocking portion 23 away from the first end 111, and the first sealing member 7 is sleeved on the shielding wire 1.

[0103] The blocking portion 23 can block the first sealing member 7 from continuing to approach the first end 111 after the first sealing member 7 contacts the shielding connector 2.

[0104] In a possible implementation, the connecting wire 100 further includes a terminal 3, the terminal 3 is arranged on the first end 111, and the terminal 3 is electrically connected with the wire 11 of the first end 111. One end of the terminal 3 is used for electrical connection with a mating plug or device, and the other end is used for electrical connection with the shielding wire.

[0105] For example, the terminal 3 is connected with the first insulating layer 13, which helps to enhance the holding force of the terminal 3 and the shielding wire 1, ensures that the current only flows in the predetermined path, avoids faults caused by accidental contact, and improves the safety of the overall system.

[0106] The terminal 3 includes a wire clamp 31 and an insulating clamp 32, wherein the wire clamp 31 is crimped with the wire 11, and the insulating clamp 32 is crimped with the first insulating layer 13.

[0107] Continuing to refer to Figure 1 In a possible implementation, along the length direction of the shielding wire 1, the shielding connector 2 and the terminal 3 are arranged at intervals, and the distance between the shielding connector 2 and the terminal 3 is less than 10 mm.

[0108] The shielding connector 2 and the terminal 3 are arranged at intervals, which facilitates the arrangement of other components between the shielding connector 2 and the terminal 3. Meanwhile, the interval arrangement of the shielding connector 2 and the terminal 3 has a physical insulation effect.

[0109] The distance between the shielding connector 2 and the terminal 3 is less than 10 mm. Thus, the distance from the shielding connector 2 to the terminal 3 is shortened, the structure inside the connecting wire 100 is more compact, and the space occupied by the connecting wire 100 is reduced.

[0110] Exemplarily, the distance between the shielding connector 2 and the terminal 3 can be one of 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm. The distance between the shielding connector 2 and the terminal 3 can be set to different intervals according to actual use scenarios.

[0111] Continuing to refer to Figure 6 In a possible implementation, the wire harness 200 includes a fixing member 5, which is accommodated inside the shielding shell 4, and the terminal 3 is accommodated in the fixing member 5.

[0112] The fixing member 5 can separate the terminal 3 from the shielding shell 4, and specifically cut off the electrical connection between the terminal 3 and the shielding shell 4. The shielding shell 4 can form a ground shield to a certain extent, reduce the influence of external electromagnetic interference on internal signals and the influence of internal electromagnetic interference on signals of other devices, and thus improve the overall performance of the device.

[0113] In a possible implementation, the wire harness 200 further includes a housing 6, which includes a receiving cavity 62 with an opening 61 on one side, the shielding shell 4 is accommodated in the receiving cavity 62, and the housing 6 is provided with a wire passing hole 63 on the side opposite to the opening 61, and the connecting wire 100 passes through the wire passing hole 63.

[0114] The housing 6 can protect the internal wires from physical damage and also insulate and protect external devices and personnel.

[0115] The housing 6 also has the functions of waterproofing and dustproofing, further enhancing the use reliability of the wire harness 200 in harsh environments.

[0116] The housing 6 further includes a self-locking device, and the housing 6 is locked and fixed to the mating plug or device through the self-locking device.

[0117] In combination with Figure 1 and Figure 6 When the fixing member 5 and the housing 6 are installed outside the shielding connector 2 and the first end 111 (see Figure 1 ) of the wire 11, the length of the fixing member 5 and the housing 6 can be shortened accordingly due to the shortened length of the shielding connector 2 to the first end 111, thereby reducing the occupied space of the connector, reducing the amount of connector material, and reducing the weight of the connector.

[0118] In a possible implementation, a second sealing member 8 is arranged between the shielding shell 4 and the housing 6, and the second sealing member 8 is annularly arranged on the inner wall plate of the housing 6. After cooperating with the mating plug or device, the inner side of the second sealing member 8 is in contact and sealed with the inner wall plate of the housing 6, and the outer side of the second sealing member 8 is in contact and sealed with the mating plug or device.
