Abstract

<P>PROBLEM TO BE SOLVED: To provide an electric cord connection device preventing a fire accident caused by a short-circuit due to dusts adhered to a plug. <P>SOLUTION: A groove 5 having appropriate depth and width is formed between terminals 4 of the plug 3 penetrating from one end to the other end, and a groove 6 corresponding to the groove 5 is formed between insertion ports 2 of a receptacle 1 as occasion calls. The short-circuit is prevented by blocking the adhered dust by the grooves 5, 6. <P>COPYRIGHT: (C)2004,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric cord connecting device for inserting a plug into an outlet for indoor wiring.

[0002]

2. Description of the Related Art It has been common practice to connect an electric cord by inserting an insertion plug into an outlet for indoor wiring. A slight clearance is generated between the surface and dust, and if dust enters through this gap and the plug is inserted for a long period of time, dust will accumulate on the surface of the plug and the outlet. No provision is made for conventional outlets and plugs.

[0003]

When dust accumulates on the surface of the insertion plug and the outlet, if the dust accumulates due to the surrounding environment, it will be energized to cause a short circuit, which will cause a fire accident. In recent years, the number of cases that induces it has become extremely large. The present invention is intended to prevent such an accident and provide a novel outlet and plug that eliminate the drawbacks of conventional products.

[0004]

As a means for achieving the above object, the present invention has a structure in which a terminal 4 of a plug 3 is inserted into an insertion port 2 of an outlet 1, and the front surface of the plug 3 is provided with the above-mentioned structure. A groove 5 having an appropriate depth and width and penetrating from one end to the other end is formed between the terminals 4, and the surface of the plug 3 on the surface between the insertion ports 2 of the outlet 1 is formed. Groove 5
Corresponding to the groove 6 of the plug 3, the groove 6 is in a load state with the groove 5 of the plug 3, and has an appropriate depth and width.
It was designed to penetrate from one end to the other.

Further, in a structure in which the terminal 4 of the plug 3 is inserted into the insertion port 2 of the outlet 1, there is an appropriate depth between the terminals 4 on the other surface of the plug 3 and the width is narrow. Forming a plurality of grooves 7 penetrating from one end to the other end, and
A plurality of grooves 8 corresponding to the grooves 7 of the plug 3 are formed on the surface between the plugs 2 of the outlet 1, and the grooves 8 are in a state of facing the grooves 7 of the plug 3 and have an appropriate degree. It was formed to have a depth and a narrow width so as to penetrate from one end to the other end.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION A specific structure of the present invention will be described with reference to the drawings. In a structure in which a terminal 4 of a plug 3 is inserted into an outlet 2 of an outlet 1, the terminal is provided on the front surface of the plug 3. A groove 5 having an appropriate depth and width is formed between the four, and the groove 5 has a large depth and width as compared with the installation place, and the plug 5 has a complete front surface from one end to the other end. It is a groove that penetrates through.

A groove 6 corresponding to the groove 5 having an appropriate depth and width between the outlets 2 on the surface of the outlet 1.
Is formed and the plug 3 is inserted, the groove 5 of the plug 3
And the groove 6 of the outlet 1 are set so as to be completely opposed to each other.

Next, a plurality (for example, two) of narrow and deep grooves 7 are formed between the terminals 4 on the front surface of the plug 3 and the grooves 7 are also provided between the insertion ports 2 of the outlet 1. A plurality of narrow deep grooves 8 are formed, and when the plug 3 is inserted, the grooves 7 and 8 are set to face each other.

Therefore, dust is unlikely to adhere to the groove 5 or the groove 7 of the plug 3, and even if dust is accumulated on the front surface of the plug 3, it is blocked by the grooves 5 and 7, and Is completely prevented, and when the grooves 6 and 8 corresponding to the grooves 5 and 7 are formed on the surface of the outlet 1, dust accumulated not only on the plug 3 side but also on the outlet 1 side Since it is blocked by the grooves 6 and 8, the above effect becomes more remarkable.

[0010]

According to the present invention, electric accidents (mainly fire accidents) caused by dust adhering to the plug 3 are completely prevented, and moreover, the deep grooves 5, 6, 7 are formed in the plug 3 or the outlet 1. , 8 is formed, there is no risk of cost increase as compared with a conventional instrument of this kind, and it has an advantage that it can be provided at a low cost.
