Description

TECHNICAL FIELD The present invention relates to a waterproof connector for a motor, and more particularly, to a waterproof connector for a motor, which facilitates handling of the motor during manufacturing and is waterproof during use.

Conventional technology Motors are widely used everywhere such as factories, buildings, households, etc., not only indoors,
Many are installed and used outdoors.

Conventionally, these motors have motor control lines for driving, speed control, and positioning that are integrally drawn from the motor body, and terminals can be attached to their ends or plugs can be attached to connect to an electric control device or power supply. Is being done.

However, in the process of manufacturing a motor, it is an obstacle to handling when the motor control line is integrally drawn out from the motor.

In addition, because of the wide variety of uses, the motor control line is unnecessarily drawn out for a long time, and the motor control line is often long and unsightly when used.

Means for Solving the Problems The present invention has been made in view of the above points, and in order to solve the above problems, a stator insertion portion provided on an upper side of a receptacle portion of a connector for a motor control line is provided. A plug that pierces the slot or coil insertion part of the motor stator to vertically hang the receptacle part against the bottom part of the motor, connect the plug to the receptacle part so that the plug can be inserted and removed, and cover along the plug. The cover is fitted into the plug so as to be inscribed in the receptacle portion, and the elastic hook-shaped hook portions projecting on both sides of the plug cover are vertically opposed to the locking portions provided on both sides of the receptacle portion. Make sure that the plug cover can be inserted and removed, narrow the motor control line outlet at the bottom of the plug cover, and slide the plug cover along the motor control line. The purpose of the present invention is to provide a waterproof connector for a motor, which is characterized in that the plug is movably covered.

According to the present invention, by inserting the receptacle part of the connector for the motor control line into the stator of the motor and allowing the plug to be inserted into and removed from the receptacle part of the connector hung on the bottom surface of the motor, Can be manufactured with the plug removed, and it is possible to prevent the motor control line from being pulled out for a long time during the manufacturing process to prevent it from interfering with handling.

Further, the plug cover can be covered with the plug cover so as to be inscribed in the receptacle part, and the elastic hooking part can be easily disengaged from the locking part by one-touch operation. Also, by narrowing the outlet of the motor control line at the bottom of this plug cover so that it can slide along the motor control line, even if the above-mentioned motor is used outdoors like an air conditioner, It is possible to prevent rainwater or water sprinkling from entering the plug from the connector hung on the motor, and to play a role as a waterproof connector, which can be easily done even when replacing the plug.

Embodiment Hereinafter, the present invention will be described based on an embodiment.

FIG. 1 and the following are embodiments of the present invention. As shown in FIGS. 1 and 2, the motor 1 for outdoor use of the air conditioner is provided with a connector 3 of a motor control line 2 for driving and controlling the motor 1 on the lower surface thereof. The connector 3 is made of a known 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 to control the motor. The wire 2 is connected to a predetermined length so that it can be pulled out, and a plug cover 6 is fitted on the outside of the plug 5 in a covered state and detachably locked to the receptacle portion 4.

As shown in FIGS. 3 and 4, the receptacle portion 4 has a mounting portion 8 attached to the motor 1 integrally projecting laterally on an upper portion in which a terminal connecting portion 7 is internally provided like a known connector. There is. As shown in FIG. 2, the mounting portion 8 has a fixed stator insertion portion 10 that pierces a slot or coil insertion portion of the stator 9 of the motor 1 and a stator contact portion 11 that contacts and positions the stator end surface. Are provided in an arcuate shape at intervals, and are attached to the stator 9 so as to sandwich the coil 12 at the end portion of the stator 9 so that they can be appropriately protruded from the motor case 13 as shown in FIGS. 1 and 2. I have to. Further, locking portions 14 that elastically lock the plug cover 6 are provided on both sides of the receptacle portion 4, and the locking portions 14
A rectangular locking hole 15 is provided in the plug cover 6 so that the plug cover 6 can be detachably locked by one-touch operation.

On the other hand, as shown in FIGS. 3 and 4, the plug 5 is connected to the connection terminal portion 16 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.
To be able to join. Then, the plug 5 is housed and the plug cover 6 is covered.

As shown in FIGS. 3 and 4, the plug cover 6 is provided with hook-shaped hooking portions 17 on both sides so as to face the locking holes 15 of the receptacle portion 4 described above, and the lower portion is narrowed. Outlet 1 so that the motor control line 2 can be pulled out
8 is opened.

As shown in FIGS. 1 and 2, since the motor 1 having the above-described configuration is attached to the outdoor device of the air conditioner, rainwater or sprinkling water from the motor case 13 or the like flows and the connector 3 gets wet. However, rainwater etc. will fall vertically along the connector 3. Since the plug cover 6 is fitted on the plug 5, rainwater and the like cannot enter the connecting terminal portion of the plug 5 above the joint between the receptacle portion 4 and the plug cover 6, and the plug cover Since the outlet 16 below 6 is narrowed down, rainwater and the like can naturally fall and effectively prevent water from entering.

Even in the manufacturing process of the motor, the receptacle portion 4 of the connector is attached to the stator 9 of the motor 1 by the attachment portion 8
Since the plug 5 and the plug cover 6 can be removed and handled simply by attaching the motor control line 2 from the motor 1, the motor control line 2 is not pulled out for a long time and does not interfere.

Furthermore, even if the plug becomes defective, the plug cover can be slid along the motor control line, so that the plug can be easily replaced.

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.

As described above, according to the present invention, the receptacle portion of the connector for the motor control line can be pierced into the stator of the motor and easily hung vertically on the lower surface of the motor.
You can prevent pulling out the motor control line for a long time,
This facilitates handling in the motor manufacturing process.

When the plug is inserted into the receptacle part and the plug cover is pushed to the outside of the plug part toward the receptacle part, the hooking parts protruding on both sides of the plug cover are inserted into the locking parts on both sides of the receptacle part and locked. , The plug cover can be securely locked to the receptacle with one touch. Further, when the elastic hooking portion is pressed and pulled, the plug cover is separated from the locking portion of the receptacle portion, and the plug can be easily removed.

Furthermore, in use, even if rainwater hits the outlet, it can be prevented from entering raindrops etc. into the internal plug by hanging down from the lower outlet through the outer surface of the receptacle part and plug cover. It is possible to prevent the occurrence of motor troubles such as air conditioners. Moreover, since the plug cover can be slid along the motor control line, it can be easily performed even when replacing the plug.
