Then, the corresponding positions of the upper housing 5 and the lower housing 6 of the connector are slidably connected. At the same time, the buffer part 10 is placed in the corresponding structure of the upper housing 5 and the lower housing 6 of the connector to complete the initial connection of the upper and lower housings. During this process, the wire harness fixing part 9 supports and fixes the wire harness body 1. Finally, the overall assembly of the wire harness connector is completed by the fixing part 7.

[0020] The connector housing 5 includes a first housing 51. A first receiving cavity 52 is provided on the side of the connector housing 5 near the wiring output end 4. The first receiving cavity 52 corresponds to the sealing ring 11. A first vertical groove 53 is fixedly connected to the middle position of the first housing 51. A first retaining edge 54 is provided at both ends of the first vertical groove 53.

[0021] The first receiving cavity 52 corresponds to the sealing ring 11, ensuring that the sealing ring 11 fits tightly with the outer shell. The first vertical groove 53 and the first flanges 54 at both ends can cooperate with the relevant structures of the lower outer shell 6 of the connector for docking of the upper and lower outer shells and installation of the buffer part 10.

[0022] The lower housing 6 of the connector includes a second housing 61. A second receiving groove 62 is provided on the side of the lower housing 6 near the wiring output end 4.

At the same time, the buffer part 10 is placed in the corresponding structure of the upper housing 5 and the lower housing 6 of the connector to complete the initial connection of the upper and lower housings. During this process, the wire harness fixing part 9 supports and fixes the wire harness body 1. Finally, the overall assembly of the wire harness connector is completed by the fixing part 7.

[0033] Compared with related technologies, the corrosion-resistant automotive chassis wiring harness connector provided by this utility model has the following advantages: The first receiving cavity 52 and the second receiving groove 62 cooperate to wrap the sealing ring 11, which is used to ensure the reliable sealing of the wiring output end 4 and prevent corrosive media such as water and mud from entering from this side. During installation, the first vertical groove 53 and the second vertical groove 64 slide to connect, taking into account the installation positioning and the placement requirements of the buffer part 10, absorbing the vibration and impact inside the wire harness connector 2, and supporting and fixing the wire harness body 1 in conjunction with the wire harness fixing part 9, increasing the stability of the wire harness connection.
