Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outlet, and more particularly to an outlet capable of preventing a fire from occurring due to heat generation in the outlet.

[0002]

2. Description of the Related Art In order to prevent an accident such as a fire due to an overcurrent of electric wiring in a home or the like, a breaker or the like provided exclusively in a switchboard is used to interrupt the supply of electricity from the original.

[0003]

However, because the breaker cannot determine the heat generation or the like at the individual outlets provided at various locations inside the room, the temperature of the specific outlet is high due to the so-called "octopus wiring". However, there was a problem that the electricity supply could not be cut off.

It is an object of the present invention to provide an outlet that shuts off the current or promptly informs the user of a dangerous state when a heat generation occurs in each outlet.

[0005]

According to a first aspect of the present invention, there is provided an "outlet provided with a male terminal and a female terminal electrically connected in a case, wherein the male terminal and the female terminal are provided. A thermal fuse disposed between the thermal fuse and the thermal fuse, which is blown when the temperature in the case reaches a predetermined temperature due to an overcurrent or a leakage current due to dust accumulated in the case, and a thermal fuse disposed on the outer surface of the case. An outlet that has a temperature change display unit that changes color when the temperature inside the case becomes abnormally high due to melting of the temperature fuse or the like, and indicates that the outlet is in an unusable state. "

According to a second aspect of the present invention, "in an outlet having a male terminal and a female terminal electrically connected in a case, a temperature arranged between the male terminal and the female terminal is provided. A fuse, which is a fuse that melts when the temperature in the case reaches a predetermined temperature due to an overcurrent or a leakage current caused by dust accumulated in the case, and between the female terminal on the female terminal side of the temperature fuse. It is connected to a pilot lamp that cannot be lit after the thermal fuse is blown, and it is arranged on the outer surface of the case.If the temperature inside the case becomes abnormally high due to the thermal fuse being blown or the like, the color will change and the outlet cannot be used. And a temperature change display means for displaying that the state has been reached. ”.

According to a third aspect of the present invention, "the temperature change display means displays a warning character, such as" danger "or" unusable ", that discontinues use of the outlet by discoloring due to temperature. Or the outlet described in 2. "
Is.

[0008]

According to the first aspect of the present invention, the male terminals of the outlet of the present invention are connected to the outlets of various places indoors, and the male plugs of various electric appliances are connected to the female terminals of the outlet of the present invention. To do. If the inside of the case reaches a predetermined temperature due to an overcurrent or a leakage current, the thermal fuse is blown, so that a fire or the like can be prevented. Also, the fact that such heat is generated is
With the temperature change display means, it is possible to easily judge from the outside, and the unusable outlet can be quickly removed.

Further, according to the invention of claim 2,
The male terminals of the outlet of the present invention are connected to outlets at various locations indoors, and the male plugs of various electric appliances are connected to the female terminals of the outlet of the present invention. Then, if the inside of the case reaches a predetermined temperature due to an overcurrent or a leakage current, the thermal fuse is blown, so that a fire or the like can be prevented. Furthermore, since the pilot lamp cannot be lit after the thermal fuse is blown, it can be promptly determined that the outlet is unusable. Further, the occurrence of such heat generation can be easily judged from the outside also by the temperature change display means, and the unusable outlet can be promptly removed.

According to the third aspect of the present invention, a warning character such as "danger" or "unusable" displayed by the temperature change display means clearly informs the user that the outlet cannot be used. it can.

[0011]

EXAMPLE An example of an outlet embodying the present invention will be described below. As shown in FIGS. 1 and 2, the outlet 1 according to the present invention includes a male terminal 3 and a female terminal 4 electrically connected to each other in a case 2 made of synthetic resin. Between the male terminal 3 and the female terminal 4,
A thermal fuse 5 is arranged to prevent a fire from occurring at a predetermined temperature (for example, 120 degrees Celsius or 150 degrees Celsius) in the case 2 due to an overcurrent or a leakage current caused by dust accumulated in the case 2. The temperature fuse 5 is blown out when the temperature reaches a temperature that can be reached.

A thermal fuse 5 is provided between the female terminals 4.
The pilot lamp 6 is connected to the female terminal 4 side of the
After the fusing, the lamp cannot be lit. A temperature change display means 7 is provided on the outer surface of the case 2, and when the temperature inside the case 2 becomes abnormally high due to melting of the temperature fuse or the like, the color changes, and the outlet 1 becomes unusable (or continuation of use). Display that the status is dangerous. The temperature change display means 7 may be formed of a sticker or the like, and may be attached to the case 2 or may be directly applied to the case 2.

The temperature change display means 7 of this embodiment is
A warning character such as "danger" or "unusable" for stopping the use of the outlet is displayed by a color change due to temperature. It is desirable that the display by the discoloration be continued even after the temperature is lowered.
Further, the temperature change display means 7 may be, for example, one that changes color from blue or white to red or the like to display a dangerous state or unusable state of the outlet.

Although the present invention has been described above according to the embodiment, it may be embodied as an outlet having two or more female terminals 4 in the case 2, or the quantity and shape of each part may be appropriately changed without departing from the scope of the claims. You may change and implement size.

[0015]

As described above in detail, according to the first aspect of the present invention, the male terminals of the outlet of the present invention are connected to the outlets and the like of various places in the room, and the male plugs of various electric appliances are provided by the present invention. Connect to the female terminal of the outlet. If the inside of the case reaches a predetermined temperature due to an overcurrent or a leakage current, the thermal fuse is blown, so that a fire or the like can be prevented. Further, the occurrence of such heat generation can be easily judged from the outside by the temperature change display means, and it has an original excellent effect that the unusable outlet can be promptly removed.

According to the second aspect of the present invention, the male terminals of the outlet of the present invention are connected to outlets at various locations indoors, and the male plugs of various electric appliances are connected to the female terminals of the outlet of the present invention. To do. Then, should the inside of the case reach a predetermined temperature due to overcurrent or leakage current,
Since the thermal fuse is blown, it is possible to prevent a fire from occurring. Furthermore, since the pilot lamp cannot be lit after the thermal fuse is blown,
It is possible to quickly determine that the outlet has become unusable. Further, the occurrence of such heat generation can be easily judged from the outside also by the temperature change display means, and it has an original excellent effect that the disabled outlet can be promptly removed.

According to the third aspect of the present invention, a warning character such as "danger" or "unusable" displayed by the temperature change display means clearly informs the user that the outlet cannot be used. It has the unique and excellent effect that it can.
