[0023] Reference Figures 1-9As shown, the slow charging wiring harness of the present invention includes a wiring harness body 1, one end of which is connected to a slow charging connector 2, and the other end of which is connected to an AC charging station 3. The slow charging connector 2 is of commercial standard structure. The AC charging station 3 includes a charging station housing 4, an insulating rubber core 5 provided in the charging station housing 4, and a rear cover 6 provided at the rear end of the charging station housing 4. The front end of the charging station housing 4 is provided with an L1 terminal plug-in cavity 7, an N terminal plug-in cavity 8, and a PE terminal plug-in cavity 9, and the insulating rubber core 5 is provided with an L1 terminal positioning groove 10, an N terminal positioning groove 11, and a PE terminal positioning groove 12. After the L1 terminal (live terminal), N terminal (neutral terminal), and PE terminal (ground terminal) are respectively inserted into the L1 terminal plug-in cavity 7, N terminal plug-in cavity 8, and PE terminal plug-in cavity 9, their rear ends are respectively positioned in the L1 terminal positioning groove 10, N terminal positioning groove 11, and PE terminal positioning groove 12 to facilitate installation. The wiring harness body 1 is fixed to the L1 terminal, N terminal and PE terminal by ultrasonic welding. A temperature sensor plug-in cavity 28 is provided next to the L1 terminal positioning groove 10 and the N terminal positioning groove 11. The temperature sensor for detecting the temperature of the L1 terminal and the N terminal can be directly plugged into the temperature sensor plug-in cavity 28 to facilitate the installation of the temperature sensor. A sealing gasket 13 is provided between the back cover 6 and the insulating rubber core 5, and the sealing gasket 13 is provided with a pin hole 14 at the position corresponding to the temperature sensor plug-in cavity 28, and a sealing film 15 is provided in the pin hole 14. During assembly, the connection pin at the rear end of the temperature sensor is inserted into the pin hole 14, and the connection is performed after piercing the sealing film 15, so that the sealing gasket 13 can seal the end of the temperature sensor. In addition, even when there is no temperature sensor installed in the temperature sensor plug-in cavity 28, due to the presence of the sealing film 15, the place is also in a sealed state. This improves the overall waterproof performance.

[0024] Preferably, a set of screw holes 16 are provided in the charging base housing 4, and the insulating rubber core 5 and the sealing gasket 13 are sequentially installed in the screw holes 16. The back cover 6 is provided with a set of mounting holes 17 corresponding to the screw holes 16. By inserting screws into the mounting holes 17 and connecting them with the screw holes 16, the overall assembly is achieved, making assembly more convenient and the assembled structure more stable.

[0025] Preferably, the sealing gasket 13 is fixed to the fixing post 18 at the rear end of the insulating rubber core 5, and the side wall of the sealing gasket 13 is provided with a set of sealing ribs 19 that seal with the inner wall of the charging base housing 4. This facilitates the installation of the sealing gasket 13 and simultaneously achieves sealing of the charging base housing 4.

[0026] Preferably, the charging station housing 4 is provided with ear holes 20 at its upper and lower ends. The upper end of the charging station housing 4 is provided with an upper retaining groove 21, and the lower end is provided with a lower retaining groove 22. The charging station housing 4 can be installed by inserting screws into the ear holes 20 or by connecting the upper retaining groove 21 and the lower retaining groove 22 to the vehicle's rails. This allows for diversified installation of the charging station housing 4 and improves installation reliability.

[0027] Preferably, a mounting buckle 23 is provided in the middle of the wiring harness body 1. The front end of the mounting buckle 23 is provided with a tapered surface 24 and the rear end is provided with an annular groove 25. The mounting buckle 23 is a plastic or rubber part. When the wiring harness body 1 is connected, the mounting buckle 23 can be inserted into the hole of the automobile sheet metal to fix the wiring harness body 1 and prevent it from shaking.

[0028] Preferably, the sealing gasket 13 is provided with a set of raised portions 26 embedded in the rear cover 6. A wire inlet hole 27 and the pin insertion hole 14 are provided on the raised portions 26. Providing the wire inlet hole 27 and the pin insertion hole 14 on the thicker raised portions 26 further improves waterproof performance. Furthermore, the positioning between the raised portions 26 and the rear cover 6 improves the stability of the sealing gasket 13 during installation.

[0029] Preferably, the wiring harness body 1 is a copper-clad aluminum cable, i.e., an aluminum core wrapped in a copper core. This structure reduces the weight of the cable, thereby reducing the weight of the entire vehicle; it also reduces costs. The copper-clad aluminum cable is a well-known technology and will not be described in detail here.

[0030] The above does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this profession can make some changes or modifications to the above-disclosed structures and technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
