As shown in FIGS. 1 and 2, a connector 1 of a motor-control line 2 for driving and controlling the motor 1 is vertically provided on the lower surface of the motor 1 for outdoor use of the air conditioner. The connector 3 is made of a known flame-retardant and weather-resistant engineering plastic, and is composed of a receptacle portion 4, a plug 5 and a plug cover 6.

The receptacle portion 4 is attached to the motor-1 side, and the plug 5 is inserted into the receptacle portion 4 so that the motor control line 2 can be connected to a predetermined length and pulled out. A plug cover 6 is fitted on the outside of the plug 5 in a covered state and is detachably locked to the receptacle portion 4.

The receptacle portion 4 is, as shown in FIGS.
The opening 4A is opened to a predetermined size , the terminal connecting portion 7 is provided inside like a known connector, and the mounting portion 9 along the motor case 8 is integrally projected on the front side thereof. The recesses 10 that fit into the motor case 8 are integrally formed on the side and the rear side thereof, and the connector 3 is detachably disposed on the lower surface of the motor 1. 1
1 is a motor stator.

Also, on both sides of the receptacle portion 4,
Locking portion 1 for locking the plug cover 6 as shown in FIGS. 3 and 5.
2 are provided so as to project, and the locking portion 12 has a rectangular locking hole 13
Is provided so that the plug cover 6 can be detachably locked.

On the other hand, as shown in FIGS. 2 and 3, the plug 5 is connected to the connection terminal portion in which the motor control line 2 is provided, and is inserted into the receptacle portion 4 to be connected to the connection terminal portion 7 of the receptacle portion 4. I am able to join. Then, the plug 5 is installed inside and the plug cover 6 is locked to the receptacle portion 4.

As shown in FIGS. 1 to 3, the plug cover 6 is provided at the lower portion of the receptacle portion 4 with a gap 1 to 3 mm around the periphery thereof.
4 is provided and the fitting part 6A is fitted into the receptacle part.
4 is slightly smaller than the opening 4A of the connector 4, and the plug 5 is inserted into the opening 4A of the terminal connecting portion 7 of the connector 3 described above to maintain the above-mentioned gap 14 and Rainwater, sprinkling water, and the like are prevented from flowing back through the gap 14 and entering. If the gap 14 is narrower than 1 mm, water easily enters due to a capillary phenomenon, and if it is wider than 3 mm, the connector 3 becomes large, which is not preferable.

On both sides of the plug cover 6, as shown in FIG.
As shown in FIG. 3, a hook-shaped hooking portion 15 having elasticity is provided so as to be opposed to the locking hole 13 of the receptacle portion 4 and the lower portion is narrowed so that the motor control line 2 can be pulled out. The outlet 16 is opened. 1
Reference numeral 7 is a drop port through which rainwater or the like that collects on the hook portion 15 drops downward.

As shown in FIG. 1 and FIG.
Since 4 is provided and fitted, even if rainwater, sprinkling water, or the like adheres to the joint portion, it is possible to reliably prevent rainwater or the like from falling and entering without causing a capillary phenomenon.

Further, since the outlet 16 below the plug cover 6 is narrowed down, rainwater and the like naturally fall,
Water can be effectively prevented from entering.

Further, even in the motor manufacturing process, it is only necessary to mount the receptacle portion 4 of the connector on the stator 11 of the motor-1 through the mounting portions 9 and the recesses 10. Since the plug 5 and the plug cover 6 can be removed and handled, the motor control line 2 is not pulled out from the motor-1 for a long time and does not interfere.

Although the outdoor motor for the air conditioner has been described above, the invention can be similarly applied to other motors installed in the same environment.
