[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0045] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0046] The Type-C wiring harness usually needs to be welded to the PCB board. For example, the prior art provides a cable connector, in which a first conductive sheet is provided on one side of the PCB board, and a power conductive sheet is provided on the other side, and the wiring harness has a first wire core and a second wire core. The first wire core needs to be welded to the first conductive sheet, and the second wire core needs to be welded to the power conductive sheet. However, the problem is that since the first conductive sheet and the power conductive sheet are respectively provided on the two sides of the PCB board, during the welding process, it is necessary to first weld the conductive sheet on one side of the PCB board and the corresponding wire core, and then weld the conductive sheet on the other side of the PCB board and the corresponding wire core after the welding is completed and the solder joints are checked. The process is complicated and the production efficiency is low.

[0047] In response to the above problems, this embodiment provides a Type-C wiring harness assembly to solve the problems of complex welding process and low production efficiency of the Type-C wiring harness in the prior art. It can be used in the field of Type-C wiring harness technology. In this embodiment, the Type-C wiring harness assembly is specifically used for new energy vehicles, and in other embodiments, the Type-C wiring harness assembly can also be used for other electronic devices.

[0048] Reference Figure 1-Figure 5The Type-C wiring harness assembly includes a wiring harness 1, a PCB board 2 and a Type-C plug 3. The wiring harness 1 includes a plurality of wires 11, some of which are signal wires, and the other part of which are power wires. The PCB board 2 has a front side and a back side, and a signal wire pin 21 and a power wire pin 22 are arranged on the front side. The signal wire pin 21 is electrically connected to the signal wire, and the power wire pin 22 is electrically connected to the power wire, so that the signal wire and the power wire are both connected to the front side of the PCB board 2. When connecting, only the pins on the front side need to be connected to the corresponding wires 11, and the processing process is simple. The Type-C plug 3 is electrically connected to the PCB board 2, so that the wires 11 are electrically connected to the Type-C plug 3.

[0049] Optionally, the width of the power line pin 22 is greater than the width of the signal line pin 21 . Specifically, the width of the power line pin 22 may be 3 to 5 times the width of the signal line pin 21 to meet the connection requirements of the signal line and the power line.

[0050] Another problem with the current processing flow of Type-C wire harnesses is that before welding the wire harness to the PCB board, the wire harness needs to be cut, stripped, cut from the outer aluminum foil, braided, laser cut from the aluminum foil, core wire aluminum foil removed, A-end wiring, A-end wire clamp, B-end wiring, B-end wire clamp, both ends inner mold forming, both ends laser cutting of the core wire outer sheath, both ends core wire stripping, tinning, etc. The process is complicated, and the above processes are mainly completed manually, with low production efficiency and difficulty in ensuring production consistency.

[0051] Please continue to refer to Figure 1-Figure 5 In this embodiment, the wiring harness 1 is a flat wire, and a plurality of conductors 11 are arranged in sequence along a first direction, so that before welding the wiring harness 1 and the PCB board 2, only wire cutting and stripping operations need to be performed, thereby further simplifying the processing flow.

[0052] Continue to refer to Figure 1-Figure 5 Along the second direction, the wiring harness 1 further includes a first insulator 12 disposed on one side of the plurality of wires 11 and a second insulator 13 disposed on the other side of the plurality of wires 11. The second direction is perpendicular to the first direction. The first insulator 12 and the second insulator 13 are provided to provide certain protection for the wires 11 and to avoid leakage and other phenomena. The wiring harness 1 further includes a blue foil 14 that simultaneously wraps the first insulator 12, the second insulator 13 and the plurality of wires 11. The blue foil 14 has certain protection and shielding functions.

[0053] Optionally, the wiring harness 1 also includes a shielding layer that wraps the first insulator 12, the second insulator 13 and the plurality of wires 11 and is arranged inside the blue foil 14, thereby further improving the electromagnetic tolerance of the wiring harness 1, protecting the wiring harness 1, and reducing electromagnetic radiation.

[0054] Continue to refer to Figure 1-Figure 5 The PCB board 2 has a first end 23 and a second end 24, the signal line pin 21 and the power line pin 22 are both arranged at the first end 23, and the Type-C plug 3 is electrically connected to the second end 24, so that the wiring harness 1 and the Type-C plug 3 are respectively connected to the two ends of the PCB board 2, which is convenient for the welding and assembly of the pins.

[0055] Continue to refer to Figure 1-Figure 5 , the second end 24 is provided with a Type-C plug connection pin, and the Type-C plug 3 has a connection end 31, and the connection end 31 is electrically connected to the Type-C plug connection pin, wherein the Type-C plug connection pin and the connection end 31 are both provided with a plurality, and the plurality of Type-C plug connection pins are connected to the plurality of connection ends 31 in a one-to-one correspondence. Optionally, some of the Type-C plug connection pins are arranged on the front side of the PCB board 2, and another part of the Type-C plug connection pins are arranged on the back side of the PCB board 2, so that the connection end 31 is respectively connected to the Type-C plug connection pins on the front side and the back side, and the purpose of such arrangement is to make the PCB board 2 compatible with the current conventional Type-C plug.

[0056] Optionally, the Type-C plug 3 has a terminal, an inner shell and an outer shell wrapping the inner shell, wherein the terminal is arranged in the inner shell, the terminal is electrically connected to the connection end 31 through an internal circuit, and is used to be electrically connected to an external structure.

[0057] This embodiment also provides a Type-C wiring harness assembly processing method, which is used to process the above-mentioned Type-C wiring harness assembly. Figure 6 The Type-C wiring harness assembly processing method includes the following steps.

[0058] S100: Cutting and stripping the wire harness 1.

[0059] Step S100 specifically includes: cutting the wire harness 1, and stripping off the first insulator 12, the second insulator 13 and the blue foil 14 at one end of the wire harness 1. This step allows one end of the wire harness 1 to be exposed, making it easier to connect it to the PCB board 2.

[0060] Since the wire harness 1 in this embodiment is a flat wire, before welding the wire harness 1 and the PCB board 2, only wire cutting and stripping operations need to be performed, which can simplify the processing flow.

[0061] S200 : Connect the signal line to the signal line pin 21 , and connect the power line to the power line pin 22 .

[0062] Among them, step S200 specifically includes step S2001-step S2003.

[0063] S2001 : pre-connecting the signal line to the signal line pin 21 , and pre-connecting the power line to the power line pin 22 .

[0064] The purpose of this step is to arrange the signal lines and power lines so that the bare drain ends of multiple signal lines can be connected one-to-one with multiple signal line pins 21, and the bare drain ends of multiple power lines can be connected one-to-one with multiple power line pins 22, to facilitate subsequent welding operations.

[0065] S2002 : Solder the signal line to the signal line pin 21 , and solder the power line to the power line pin 22 .

[0066] The signal line is connected to the signal line pin 21 by welding, and the power line is connected to the power line pin 22 by welding. In addition, since the signal line pin 21 and the power line pin 22 are both arranged on the front side of the PCB board 2, when welding, only the pins on the front side need to be welded to the corresponding wires 11, and the processing process is simple.

[0067] S2003: Check the solder joints and apply glue on them.

[0068] Specifically, UV glue is applied to the soldering points, which can be cured after being irradiated by ultraviolet light.

[0069] S300: connects PCB board 2 and Type-C plug 3.

[0070] Specifically, the Type-C plug connection pin of the PCB board 2 is connected to the connection end 31 of the Type-C plug 3, and the connection can also be performed by welding.

[0071] S400: Test the Type-C cable harness assembly.

[0072] Among them, in step S400, the tests performed on the Type-C wiring harness assembly include insulation withstand voltage test, conduction test and audio and video test to test the performance of the Type-C wiring harness assembly and whether each function can be used normally.

[0073] Optionally, after the connection between the PCB board 2 and the Type-C plug 3 is completed, the size of the Type-C harness assembly will also be measured, including measuring the exposed size and the total length of the finished product.

[0074] In the above-mentioned Type-C harness assembly processing method, the harness 1 is cut and stripped, the signal line is connected to the signal line pin 21, and the power line is connected to the power line pin 22. In this step, since the signal line pin 21 and the power line pin 22 are both arranged on the front of the PCB board 2, when connecting, it is only necessary to connect the front pins with the corresponding wires 11, and the processing process is simple. Connect the PCB board 2 and the Type-C plug 3, so that the wire 11 is electrically connected to the Type-C plug 3; test the Type-C harness assembly to complete the processing of the Type-C harness assembly.

[0075] The following combination Figure 7-Figure 8 An example is given to illustrate the effect of the Type-C wiring harness assembly processing method in the embodiment of the present invention.

[0076] One of the processing procedures of Type-C wiring harness assembly in the prior art is as follows: Figure 7 As shown in FIG. 1 , a total of 33 processes are included. In this embodiment, the structure of the Type-C harness assembly is improved. Specifically, the harness 1 is in the form of a flat wire, and the signal line pin 21 and the power line pin 22 are both arranged on the front of the PCB board 2. In this way, the processing steps can be reduced to 17. Figure 8 shown.

[0077] Continue to refer to Figure 7-Figure 8 Since the harness 1 of the Type-C harness assembly adopts the form of a flat wire, the processes of cutting the outer aluminum foil, ring braiding, laser cutting the aluminum foil, removing the core wire aluminum foil, A-end wiring, A-end wire clamping, B-end wiring, B-end wire clamping, both ends internal mold forming, laser cutting the outer sheath of the core wire at both ends, stripping the core wire at both ends, and tinning before welding in the prior art can be omitted. In addition, since the harness 1 adopts the form of a flat wire, it is not necessary to wrap high-temperature adhesive tape, rivet the shielding shell, and build the ground wire. At the same time, the insulation withstand voltage and conduction tests after riveting the shielding shell and building the ground wire are omitted. The insulation withstand voltage and conduction tests can be uniformly performed after laser welding the shielding shell. In addition, since the signal line pins 21 and the power line pins 22 are both arranged on the front of the PCB board 2, it is only necessary to weld the front of the PCB board 2 and the corresponding wire 11, and the process of welding the back of the PCB board 2 and the corresponding solder joint inspection process can be omitted.

[0078] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
