DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to FIGS.
FIG. 1 shows a schematic configuration of an outdoor unit of an air conditioner. A main body of the outdoor unit includes a bottom plate (base) 1 and an outer trunk, and the outer trunk is formed continuously with the left side plate 2a. The front cover 2, a right side plate 3 formed in an L shape, an upper surface cover 4, and the like, and the inside of the main body are partitioned by a partition plate 5 erected on the bottom plate 1 and a heat exchange chamber 6 and a machine chamber 7. The heat exchange chamber 6 is provided with a heat exchanger 8 and a blower fan 9 for sending the air heat-exchanged by the heat exchanger 8 to the outside. The compressor 10 is disposed, and an electrical component 11 that houses electrical components for performing operation control of the compressor 10 and the blower fan (blower) 9 is disposed above the compressor 10.
[0011]
As shown in FIG. 2, the electrical component section 11 is made of a resin material and has an open electrical circuit board storage case 13 that houses the electrical circuit board 12, and an open top surface that houses and holds the electrical circuit board storage case 13 made of sheet metal. The electrical component box 14 and a box-shaped electrical component lid 15 covered from the upper surface of the electrical component storage case 13 are arranged on both side walls of the electrical component storage case 13 and the electrical component box 14. In this configuration, concave lead wire take-out portions 13a and 14a for taking out the lead wire 16 from the lead wire 16 are provided.
[0012]
FIG. 3 is an enlarged view of the main part of the present invention. A flange 13b that covers the opening edge of the lead wire take-out portion 14a of the electrical component box 14 is formed in the lead wire take-out portion 13a of the electrical board storage case 13. The locking piece 13c is integrally formed at the lower end of the lower end, and the locking piece 13c is locked to the lead wire take-out portion 14a of the electrical component box 14.
[0013]
FIG. 4 is a cross-sectional view showing the main part form (A-A arrow in FIG. 3) after assembling the electric part 11 having the above-described configuration, and is provided in the lead wire extraction part 13 a of the electric board storage case 13. Since the flange 13b covers the opening edge of the lead wire take-out portion 14a of the electrical component box 14 and the locking piece 13c is locked to the lead wire take-out portion 14a of the electrical component box 14, the lead wire 16 Does not touch the opening edge of the lead wire take-out portion 14a on the electrical component box 14 side, so that the lead wire 16 can be prevented from being damaged, and the lead wire 16 taken out from the lead wire take-out portion 13a is locked. Since it is sandwiched between the piece 13c and the electrical component lid 15 formed so as to hide the lead wire take-out portion 13a, it is possible to prevent water from entering the inside without using a sealing material or the like.
[0014]
The locking pieces 13c shown in FIGS. 3 and 4 are provided only at the lower end of the substantially concave flange 13b. However, the present invention is not limited to this configuration. It may be provided over the entire tip.
[0015]
【The invention's effect】
In the case of an electrical component having the above-described configuration, an auxiliary member such as a sealing material is unnecessary, so that assembly is easy and cost can be reduced. Furthermore, lead wires are damaged or water enters from the outside. This also contributes to improving the quality and safety of the outdoor unit.
