[0036] Working principle: The wire harness is passed through the cavity in the center of the sealing plug 4 and the nut 5. Then, the sealing plug 4 is placed into the mounting groove 3. Using a special tool, the copper nut 5 is rotated. The nut 5 rotates and moves downward in the internal thread groove of the mounting groove 3, gradually pressing the sealing plug 4. The sealing plug 4 is squeezed by the nut 5, and its outer wall fits tightly against the inner wall of the mounting groove 3, thus sealing and waterproofing the area where the wire harness exits. By setting two sets of mounting grooves 3, two sets of wire harnesses can be passed in at the same time, meeting the needs of multiple wire harness exits. This sealing method does not require the use of glue, ensuring a good sealing effect and making the overall appearance more aesthetically pleasing.
