Description

Technical Field

[0001] This utility model belongs to the field of new energy vehicle parts technology, specifically relating to a tailgate strut wiring harness based on USB Type-C. Background Technology

[0002] With the development of the new energy vehicle industry, electric tailgates are becoming increasingly popular among consumers. As the driving component of electric tailgates, the electric tailgate strut needs to have good ease of installation and stability. Existing electric tailgate struts typically use welding to connect the wiring harness to the strut, which is complex and costly. Furthermore, when the wiring harness is used for a long time, electrical faults may occur due to aging, such as leakage or short circuits caused by insulation aging, or poor contact due to terminal oxidation. Repairing these faults requires replacing both the tailgate strut and the wiring harness, resulting in high repair costs.

[0003] Therefore, the above problems urgently need to be solved. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the above shortcomings, this utility model provides a tailgate strut wiring harness based on USB Type-C, which transforms the traditional welding connection method of tailgate strut and wiring harness into a USB connection method, thereby improving production efficiency and assembly convenience, realizing reversible insertion function, and improving assembly convenience.

[0005] Technical Solution: To achieve the above objectives, this utility model provides a tailgate strut wiring harness based on USB Type-C, including a USB plug, a USB socket, and a multi-core wire. The USB plug and USB socket are electrically connected via the multi-core wire, and are mutually plugged into each other. The USB plug includes a protective shell, and a terminal group is connected to the inner wall of the protective shell via an insulating sleeve. The terminal group includes an upper row of terminal groups and a lower row of terminal groups, which are centrally symmetrically arranged. The upper row of terminal groups includes an upper row of positive power terminals, an upper row of negative power terminals, and an upper row of signal terminals. The lower row of terminal groups includes a lower row of positive power terminals, a lower row of negative power terminals, and a lower row of signal terminals. The upper and lower rows of positive and negative power terminals are correspondingly arranged, as are the upper and lower rows of negative power terminals and signal terminals. This invention relates to a dedicated automotive wiring harness based on a USB Type-C interface. It transforms the traditional welding connection between the tailgate support and the wiring harness into a plug-in connection, allowing for independent production of the tailgate support and wiring harness, thus improving production efficiency and reducing costs. Furthermore, the connection method between the tailgate support and the wiring harness is convenient and improves ease of connection. Additionally, power terminals of the same polarity are located on the upper and lower sides of the protective housing opening, and symmetrically arranged signal terminal groups ensure that the power polarity remains unchanged when the plug is flipped, enabling reversible insertion and improving assembly convenience.

[0006] Furthermore, in the aforementioned USB Type-C-based tailgate strut wiring harness, the upper power supply negative terminal group includes a first upper power supply negative terminal group and a second upper power supply negative terminal group, which are respectively located on both sides of the upper power supply positive terminal group. The lower power supply negative terminal group includes a first lower power supply negative terminal group and a second lower power supply negative terminal group, which are respectively located on both sides of the lower power supply positive terminal group. By having two power supply negative terminal groups, each located on both sides of the power supply positive terminal group, the current carrying capacity of the wiring harness is improved, resulting in a symmetrical current distribution and enhanced electromagnetic compatibility.

[0007] Furthermore, in the aforementioned USB Type-C-based tailgate strut wiring harness, the upper row of signal terminal blocks includes an upper Hall effect signal A contact, an upper Hall effect signal B contact, an upper Hall effect ground contact, and an upper Hall effect power contact; these contacts are arranged from the first upper power negative terminal group to the second upper power negative terminal group. The lower row of signal terminal blocks includes a lower Hall effect power contact, a lower Hall effect ground contact, a lower Hall effect signal B contact, and a lower Hall effect signal A contact; these contacts are arranged from the first lower power negative terminal group to the second lower power negative terminal group. The Hall effect signal A contact and the Hall effect signal B contact can meet the signal transmission requirements of the tailgate strut.

[0008] Furthermore, in the aforementioned USB Type-C-based tailgate strut wiring harness, the upper Hall signal A contact and the upper Hall signal B contact are located between the first upper power supply negative group and the upper power supply positive group, while the upper Hall ground contact and the upper Hall power contact are located between the upper power supply positive group and the second upper power supply negative group. The lower Hall power contact and the lower Hall ground contact are located between the first lower power supply negative group and the lower power supply positive group, while the lower Hall signal B contact and the lower Hall signal A contact are located between the lower power supply positive group and the second lower power supply negative group. Positioning the signal terminals between the power supply positive and negative groups increases the distance between the positive and negative terminals, reducing the risk of short circuits and improving safety. Separating the power contacts and signal contacts reduces power supply interference with the signal and improves signal stability.

[0009] Furthermore, in the aforementioned USB Type-C-based tailgate support harness, the upper row of positive power contacts is spaced apart, and the contacts in the upper row of positive power contacts are arranged in an array from the first upper negative power contact group to the second upper negative power contact group. The upper and lower rows of positive power contacts each have eight contacts for the positive power terminals, improving the current-carrying capacity of the harness.

[0010] Furthermore, in the aforementioned USB Type-C-based tailgate strut wiring harness, the first upper power negative terminal group and the second upper power negative terminal group each have two contacts, and the first lower power negative terminal group and the second lower power negative terminal group each have two contacts. The power negative terminals have eight contacts, improving the current-carrying capacity of the wiring harness.

[0011] Furthermore, in the aforementioned USB Type-C-based tailgate strut wiring harness, the multi-core wire includes a positive power line, a negative power line, a Hall A signal line, a Hall B signal line, a Hall power line, and a ground wire. The positive power line is electrically connected to the contacts respectively provided on the upper and lower positive power supply groups. The negative power line is electrically connected to the contacts respectively provided on the upper and lower negative power supply groups. The Hall A signal line is electrically connected to the upper Hall signal A contact and the lower Hall signal A contact. The Hall B signal line is electrically connected to the upper Hall signal B contact and the lower Hall signal B contact. The Hall power line is electrically connected to the upper Hall power contact and the lower Hall power contact. The ground wire is electrically connected to the upper Hall ground contact and the lower Hall ground contact.

[0012] Furthermore, in the aforementioned USB Type-C-based tailgate strut wiring harness, the multi-core wire is fitted with a circular rubber sleeve. The multi-core wire is mounted to the vehicle frame via this sleeve, reducing friction between the harness and the frame, preventing damage to the harness due to friction, and improving safety.

[0013] Furthermore, in the aforementioned USB Type-C based tailgate strut wiring harness, the protective housing has a flat, round cross-section. This flat, round protective housing facilitates foolproof insertion.

[0014] Furthermore, in the aforementioned USB Type-C based tailgate strut wiring harness, the USB plug is inserted into a socket provided on the tailgate strut.

[0015] As can be seen from the above technical solution, this utility model has the following beneficial effects:
