Please refer to Figures 1-4, the present invention provides a technical solution: an electrical box for the use of an air conditioner external unit, including a lower box body 1, an upper box body 2, a connecting wire 3, a threaded rod 4, a vertical plate 5, Circuit board 6, inner box main body 7, through hole 8, protective block 9, connecting rod 10, limit groove 11, installation groove 12 and back-moving spring 13, upper box main body 2 is installed on the upper surface of lower box main body 1, and lower The left side of the box main body 1 is equipped with a threaded rod 4, and the outside of the lower box main body 1 is equipped with a connecting wire 3, the inside of the lower box main body 1 is fixed with an inner box main body 7, and the inside of the inner box main body 7 is equipped with a circuit board 6 , and the outer side of the inner box main body 7 is provided with a threaded rod 4, the outer side of the threaded rod 4 is threaded with a riser 5, and the inside of the riser 5 is provided with a through hole 8, and the left and right sides of the through hole 8 are provided with limiting grooves 11. The outer end of the limiting groove 11 is equipped with a mounting groove 12, and the outside of the limiting groove 11 and the mounting groove 12 are fixed with a vertical plate 5, and the inside of the through hole 8 is provided with a protective block 9, and the outer surface of the protective block 9 A connecting rod 10 is fixed at the end, and the outer end of the connecting rod 10 is connected with the mounting groove 12 through a return spring 13;

Riser 5 forms a sliding structure with lower box main body 1 through threaded rod 4, and the thickness of riser 5 is greater than the distance between the inner surface of inner box main body 7 and the outer surface of lower box main body 1, and then facilitates vertical plate 5 in moving During the process of pulling and placing the connecting line 3;

The highest point of the inner box main body 7 is lower than the highest point of the lower box main body 1, and the inner box main body 7 and the lower box main body 1 are an integrated structure, and between the inner side of the inner box main body 7 and the outer side of the lower box main body 1 There is a spacing, thereby facilitating the placement of excess length of connecting wire 3 in the gap between the inner box body 7 and the lower box body 1;

The vertical centerline of the through hole 8 is on the same straight line as the vertical centerline of the vertical plate 5, and 1/2 of the perimeter of the through hole 8 is greater than the arc length of the protective block 9, so that the through hole 8 can be well aligned Place the connection line 3;

The inner side and the outer side of the protective block 9 are arc-shaped structures, and the protective block 9 is arranged symmetrically with respect to the vertical center line of the through hole 8, and the protective block 9 forms a sliding structure with the vertical plate 5 through the connecting rod 10 and the return spring 13 , so that the protective block 9 is in good contact with the connecting line 3 and protected, reducing the friction between the connecting line 3 and the riser 5;

The space inside the limiting groove 11, the through hole 8 and the installation groove 12 are all connected, and the limiting groove 11 and the installation groove 12 form a "T" shape structure, and the inner surface of the limiting groove 11 is an arc-shaped structure, This facilitates the sliding of the protection block 9 in the limiting groove 11 .

Working principle: when using the electrical box used for the air conditioner external unit, first, assemble and install the inside of the whole device, as shown in Figure 2, install the circuit board 6 in the main body 7 of the inner box, and then install the One end of the connecting wire 3 is installed on the upper surface of the circuit board 6, and then the other end of the connecting wire 3 is sequentially inserted into the corresponding through hole 8 inside the vertical plate 5, as shown in Figure 3-4. After that, the other end of the connecting wire 3 is installed through the mounting hole inside the inner box main body 7 and the lower box main body 1 and the outer side of the lower box main body 1, as shown in Figure 1, at this time, when the connecting wire When the length of 3 is longer, manually rotate the corresponding threaded rod 4, and the threaded rod 4 drives the vertical plate 5 connected by the outer thread to move to the left when the threaded rod 4 rotates, so that the vertical plate 5 pulls the internal connecting line 3 through the through hole 8, Make the connecting line 3 of excess length be placed in the shape of "U" in the gap between the lower box main body 1 and the inner box main body 7, as shown in Figure 2;

Thus, the longer connecting wire 3 is well placed to prevent the connecting wire 3 from being exposed on the outside of the lower box main body 1.
