The extension length of the second weakened slit 2331 is set to be greater than the protruding length of the sealing protrusion 11, so that when the sealing protrusion 11 presses against the sealing portion 231, the wire body can easily pass through the second weakened slit 2331 and be placed in the first weakened slit 2312, avoiding blocking the wire body, making the threading of the wire body more convenient and saving operation time.

[0071] In some embodiments, the protruding direction of the sealing protrusion 11 is the same as the extending direction of the second weakened seam 2331 .

[0072] Specifically, the sealing protrusion 11 is constructed to protrude toward the wire groove 22, and the protruding direction of the sealing protrusion 11 is the same as the extending direction of the second weakened slit 2331, and when the protruding direction of the sealing protrusion 11 is upward, the opening direction of the second weakened slit 2331 is downward, and when the protruding direction of the sealing protrusion 11 is downward, the opening direction of the second weakened slit 2331 is upward, and the second weakened slit 2331 is arranged on the shielding portion 233, and the shielding portion 233 is provided with the second weakened slit 2331, which can shield the sealing portion 231 while realizing the threading of the wire body, thereby improving the sealing performance. When the box cover 1 is connected to the box body 2, the sealing protrusion 11 presses against the sealing portion 231, The protruding direction of the sealing protrusion 11 is the same as the extending direction of the second weakened seam 2331, and the protruding direction of the sealing protrusion 11 is also the same as the extending direction of the first weakened seam 2312, that is, the extending direction of the first weakened seam 2312 is the same as the extending direction of the second weakened seam 2331. When the sealing protrusion 11 is pressed against the first weakened seam 2312, it can be pressed along the extending direction of the first weakened seam 2312, and the wire body can also be passed through the first weakened seam 2312 through the second weakened seam 2331, so that the sealing part 231 can protect the sealing part 231 while ensuring the sealing effect of the first weakened seam 2312, thereby extending the service life of the sealing part 231.

The wire passing groove 22 can be passed through by the wire body. When the box cover 1 is connected to the box body 2, the sealing convex portion 11 can be placed in the wire passing groove 22 to press against the sealing portion 231 installed in the wire passing groove 22, so as to achieve sealing of the electric control box 100 when the wire body is passed through the electric control box 100. The wire passing groove 22 can be set to multiple, and the sealing convex portion 11 can also be set to multiple. The multiple sealing convex portions 11 are distributed in a one-to-one correspondence with the multiple wire passing grooves 22, that is, after the wire body is passed through the wire passing groove 22, the corresponding sealing convex portion 11 presses against the sealing portion 231 in the wire passing groove 22 to seal the electric control box 100 and improve the sealing performance. The provision of multiple wire passing grooves 22 makes the wire body arrangement more uniform, and there are fewer wire bodies in each sealing portion 231, which can also improve the sealing performance and improve the reliability of the electric control box 100.
