Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric connection device for a bathroom.

[0002]

2. Description of the Related Art Conventional electrical connections in bathrooms and the like have been made with waterproof connectors as shown in FIG. That is, this is done by connecting the female side waterproof connector section 1 and the male side waterproof connector section 2 in the bathroom. The electric wire covering portion 3 is passed through the rubber packing 4 for sealing. A rubber packing 6 is provided on the outer periphery of the housing portion 5 of the female-side waterproof connector portion 1 and seals between the male-side waterproof connector portion 2 and the housing portion 7.

[0003]

However, the above-mentioned conventional waterproof connector is small in size and made for a professional worker, so it is difficult to connect. Also, once connected, it was left as it was, and it was not designed so that it could be connected and disconnected many times. In addition, the conventional waterproof connector ensures waterproofness after connection, and does not consider waterproofness before connection.

[0004]

In order to solve the above-mentioned problems, the present invention firstly provides the plug portion insertion portion of the connector portion and the outer periphery of the plug portion with concave and convex portions which are fitted to each other.

According to the above invention, a general user can easily insert and remove the plug portion many times, and the connection error does not occur.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The invention according to claim 1 of the present invention comprises a connector part having a control part having a partition wall around it and a female electrode, and a plug part connected to this connector part, The plug insertion port of the connector part and the outer periphery of the plug part are provided with irregularities that fit with each other.
It can be inserted only in the fitting direction of the concavo-convex, so that a general user can easily insert the power supply without making a mistake in the polarity.

In the invention according to claim 2 of the present invention, when the plug portion is dropped on the floor by providing an intermediate rod having a height higher than that of the electrode portion in the central portion of the two electrodes of the plug portion. In, the electrode can be protected by first hitting the floor with the intermediate rod.

In the invention according to claim 3 of the present invention, by making both the connector portion and the plug portion simply fixed, it is possible to reduce the load on the electrode connecting portion, and to connect the electrodes. Hard to come off and easy to remove.

In the invention according to claim 4 of the present invention, since the elastic body with the slit is used for the plug electrode insertion portion of the connector portion, it becomes difficult for water to enter when the plug portion is removed. .

In the invention according to claim 5 of the present invention, the electrode portion of the plug portion and the intermediate rod are integrally molded with a resin having high adhesiveness, so that the water inside the plug portion can be removed from the plug portion alone. Intrusion can be prevented.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view of a bathroom electrical connection device of the present invention when a plug and a connector portion are connected. In the figure,
Reference numeral 1 is a connector section, and power is input through a power line 2. Reference numeral 3 denotes a control unit, which has a partition wall 4 around it and a switch 5. Reference numerals 6 and 7 are first and second female electrodes. 8 is a plug part, 9 and 10 are the first of the plug parts,
The second male electrode. Reference numeral 11 is an intermediate rod, and 12 is a fixing spring.

Since the recess 13 provided in the intermediate rod 11 has a simple fixing structure in which the fixing spring 12 holds it, the plug portion 8 can be easily fixed and can be inserted / removed. Further, by integrally molding the first and second male electrodes 9 and 10 of the plug portion 8 and the intermediate rod 11, it is possible to prevent water from entering the inside.

FIG. 2 is a perspective view showing a connection state between the connector portion and the plug portion. As shown in the figure, the plug insertion port 14 of the connector 1 and the outer periphery of the plug 8 are provided with irregularities 15 which are fitted to each other, so that they cannot be connected except in the fitting direction.

The intermediate rod 11 is several millimeters higher than the first and second male electrodes 9 and 10 of the plug portion 8 and protects the first and second electrodes 9 and 10.

By providing the elastic member 17 having the slit 16 in the insertion port portion 14, it is possible to prevent water from entering even when the plug portion 8 is removed.

[0016]

As described above, in the invention according to claim 1 of the present invention, a general user can easily connect the power source without making a mistake in the polarity of the power source.

According to the second aspect of the present invention, the plug electrode portion can be protected.

Further, in the invention according to claim 3, the connector portion and the plug portion can be easily fixed and can be inserted and removed.

The invention according to claim 4 can prevent water from entering the connector portion even when the plug portion is removed.

Further, in the invention according to claim 5, in the plug alone, it is possible to prevent water from entering the inside of the plug.
