Generally speaking, the wiring harness connector is mainly composed of a terminal, a housing, a fixing frame, a sealing part, a locking part, etc.

[0003] The existing automotive wiring harness connector can specifically refer to the waterproof automotive wiring harness connector with application number: CN202122931895.9, which belongs to the technical field of wiring harness connectors. The key points of its technical solution include a plug-in and a connector plug-in. A receiving groove matching the connector plug-in is opened on the right side of the plug-in. Top blocks are fixedly connected to the inner side walls of the receiving groove. A fixing frame cover is fixedly connected to the outer side wall of the connector plug-in. The fixing frame cover is located on the right side of the plug-in, and the inner side wall of the fixing frame cover is tightly attached to the outer side wall of the plug-in. A mounting frame is fixedly connected to the outer side wall of the plug-in. A sealing gasket is arranged between the mounting frame and the fixing frame cover. The locking block at the right end of the guide rod penetrates the outside of the guide hole. The locking block is rotated to stagger the locking block with the guide hole so that the locking block cannot move. The butterfly screw is manually rotated so that the butterfly screw fixes the locking block and the fixing frame cover so that the fixing frame cover and the mounting frame will not be separated, thereby ensuring that the plug-in and the connector plug-in will not loosen or fall off.
