[0033] The present application will be further described in detail below in conjunction with the accompanying drawings and implementation methods. It is to be understood that the present application can be implemented in various forms and should not be limited by the implementation methods described herein. On the contrary, these implementation methods are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art. It is also necessary to explain that, for ease of description, only the parts related to the present application are shown in the accompanying drawings.

[0034] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] The electrical connector is an important component of the electrical connection in the vehicle, and it has a very wide range of uses. The current signal is transmitted through the cable 10. Usually, the structure of the cable 10 includes a core 13, an insulating layer 14, a shielding layer 11 and an insulating sheath 12 from the inside to the outside. The core 13 is used to transmit the working current of the vehicle electrical connection. The insulating layer 14 is used to isolate the working current from the shell 30 to ensure the normal operation of the electrical connector. A magnetic field will be generated around the current, and the microcurrent generated in the magnetic field will interfere with the vehicle control signal. Therefore, a shielding layer 11 is provided outside the core 13 to confine the microcurrent in the shielding layer 11, and then the current in the shielding layer 11 is introduced into the shell 30. The insulating sheath 12 protects the cable 10. Figure 1-2As shown, the conventional cable 10 has an insulating sheath 12 on the outside, so it cannot be directly crimped into the shielding connection ring 20. The copper wire needs to be turned over, and a shielding crimping ring 27 is provided to crimp the copper wire into the annular area formed between the shielding connection ring 20 and the shielding crimping ring 27, so as to conduct the current in the shielding layer 11. This assembly method has many assembly parts and complicated assembly procedures.

[0036] The embodiment of the first aspect of the present application provides a cable 10, such as Figure 3 As shown, it includes a shielding layer 11, and the shielding layer 11 is suitable for crimping in the shielding connection ring 20. The shielding layer 11 includes a support body 19 and a metal wire 16 supported on the support body 19, and the metal wire 16 is suitable for conducting the induced current generated by the core 13. Among them, the cable 10 structure provided by the embodiment of the present application does not have an insulating sheath 12, but only has a support body 19 in the shielding layer 11, and the metal wire 16 is supported on the support body 19, so that the shape of the metal wire 16 is fixed without bending and deformation. Therefore, the shielding layer 11 can be directly crimped with the inner ring of the shielding connection ring 20 without considering the short circuit formed by the metal wire 16 after the flanging and bending, and there is no need for the shielding crimping ring 27 to fix the shape of the metal wire 16, which saves assembly parts and reduces assembly processes.

[0037] When making the shielding layer 11 of the cable, one of the support body 19 and the metal wire 16 can be first set on the cable 10, and the other of the support body 19 and the metal wire 16 can be filled thereon by injection molding to form a shielding layer 11 structure in which the metal wire 16 is supported on the support body 19.

[0038] like Figure 1 and Figure 2 In the related prior art, during crimping, the shielding layer 11 outside the insulating sheath may have the risk of piercing the insulating sheath 12. After piercing the insulating sheath 12, the shielding layer 11 short-circuits, causing damage to the cable 10.

[0039] To prevent the shielding layer 11 from short circuiting, preferably, Figure 3 As shown, the support body 19 includes a plurality of insulating wires 15, and the number of the metal wires 16 is a plurality, and the plurality of metal wires 16 and the plurality of insulating wires 15 are intertwined and distributed in the shielding layer 11. The plurality of metal wires 16 can improve the conductive shielding effect, and the use of the insulating wires 15 as the support body 19 can insulate the plurality of metal wires 16 from each other to avoid short circuits, and can form an intertwined distribution structure to improve the strength of the support structure.

[0040] Preferably, the insulating wires 15 and the metal wires 16 are distributed in a mesh structure, which can improve the tensile strength and bending resistance of the shielding layer 11 and reduce the occurrence of cracks in the cable 10 .

[0041] An embodiment of a second aspect of the present application provides an electrical connector, including the cable provided by the embodiment of the first aspect, for electrically connecting electrical equipment.

[0042] Alternatively, if Figure 4-Figure 8 As shown, the electrical connector includes a shell 30 and a shielding connecting ring 20. The shielding connecting ring 20 and the cable 10 are arranged in the shell 30. The shielding connecting ring 20 is sleeved outside the shielding layer 11. For example, the shielding layer 11 can be crimped into the shielding connecting ring 20, and the shielding connecting ring 20 is electrically contacted with the shell 30, so that the micro-current in the shielding layer 11 is first conducted to the shielding connecting ring 20, and then conducted to the electrical connector shell 30 through the shielding connecting ring 20.

[0043] Alternatively, if Figure 4-Figure 5 As shown, the shielding connection ring 20 includes an annular body 21; the annular body 21 is sleeved outside the shielding layer 11, and a plurality of contact portions 24 are provided in the circumferential direction of the annular body 21, and the plurality of contact portions 24 are electrically contacted to the shell 30. In this embodiment, the plurality of contact portions 24 are electrically contacted to the shell 30, thereby improving the shielding effect. Furthermore, the plurality of contact portions 24 have a certain elasticity, and when in electrical contact, the plurality of contact portions 24 are squeezed and deformed to have a certain pre-stress, thereby ensuring the electrical contact effect between the contact portions 24 and the shell 30.

[0044] Optionally, a limiting step 26 and a seal 23 are provided in the housing 30, and the annular body 21 is clamped between the limiting step 26 and the seal 23. During assembly, the cable 10 and the shielding connection ring 20 are pressed and inserted into the housing 30 until one side of the annular body 21 abuts against the limiting step 26, and then the seal 23 is provided on the other side of the annular body 21 to fix the annular body 21, and then fix the cable 10, so as to ensure the electrical connection stability of the cable 10. The seal 23 may be a rubber filler.

[0045] Optionally, the plurality of electrical contacts 24 are respectively abutted against the limiting steps 26, and the annular body 21 is further provided with an annular boss 22, and the sealing member 23 abuts against the annular boss 22. In this way, the annular boss 22 can increase the contact area between the annular body 21 and the sealing member 23, and improve the fixing effect of the annular body 21; especially when a rubber filler is used as the sealing member 23, the annular boss 22 can block the flow of the rubber filler when the rubber filler is not completely solidified, and prevent the insulating rubber filler from affecting the conductive shielding performance of the electrical contact 24.

[0046] Optionally, the annular boss 22 is disposed on the axial end of the annular body 21, and the plurality of electrical contacts 24 are disposed on the other axial end of the annular body 21. In this way, the annular boss 22 and the electrical contact 24 can be formed by folding the annular body 21 outwards, which is convenient for manufacturing, that is, in a further embodiment, the annular body 21, the annular boss 22 and the plurality of electrical contacts 24 are an integral part, which reduces the assembly process and improves the production cycle; at the same time, it can also better block the flow of the rubber filler.

[0047] The rubber filling piece may specifically be silicone rubber.

[0048] When assembling the electrical connector provided by the second aspect of the embodiment of the present application, the annular boss 25 and the shielding connection ring 20 are first inserted into the cable 10, and then the terminal 17 is welded to the cable 10, and the shielding connection ring 20 is crimped onto the cable 10 according to the assembly size, and then the cable 10 is inserted into the shell 30 from back to front, the end cover and the shell 30 are connected and fixed by snap-fit ​​limiters, the terminal 17 is inserted into the end cover 18, and the rubber filler is sealed inside the connector shell 30 by an automatic glue filling machine. After the rubber filler is completely cured, the annular baffle 25 is set to cover the side of the rubber filler away from the annular boss 22, and the annular baffle 25 is fixed to the shell 30.

[0049] A third aspect of an embodiment of the present application provides a vehicle, comprising the cable of the first aspect and the electrical connector of the second aspect.
