Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electrical outlet with a built-in power switch, in which the electrical outlet has a built-in power switch.

Traditionally, the usage of electrical outlets in general households has been such that electrical appliances such as televisions, radios, electric kotatsus, and air conditioners have been used to connect to electrical outlets that are attached to wall members indoors, etc., even though we know this is not very desirable. Usually, one or more power plugs are left plugged in and energized at all times, and during actual use, the on/off operation is performed using a switch attached to the electrical product. The biggest problem with such usage is that the outlet built into the wall or the like and the plug inserted into the outlet are always connected and energized.

In other words, electricity is maintained between the outlet and the plug simply by a connection called "contact", regardless of the use of the electrical appliance, and there is no element of disconnection in this. If this condition continues for a long period of time, the relationship between the outlet and the plug may be due to aging of the product and the plug is not completely inserted into the outlet hole and is about to fall out, or if the two are not energized by simply contacting them. If an oxide film is formed on the surface of a metal object, if the switch of an electrical appliance connected to the oxidized film is turned on, the contact resistance of the contact part will cause the part to heat up and cause a fire or heat generation. The deterioration of the insulating parts due to this may cause accidents such as I-electric power, and may become a major factor in a house fire, for example, while the person is away or asleep. The main reason for this is that because conventional electrical outlets do not have a built-in power switch, electrical appliances are often left plugged into the electrical outlet and left turned on, which is a major drawback of conventional electrical outlets. .

This invention was made to eliminate these drawbacks of conventional electrical outlets, and by incorporating a power switch or overcurrent breaker switch into the electrical outlet, it is possible to prevent disasters caused by leaving electrical appliances unplugged. It is an object.

Hereinafter, the present invention will be explained in detail with reference to the drawings based on examples.

Fig. 1 is an electric circuit diagram of an embodiment of the present invention, and Fig. 2 is a perspective view of its external appearance. A two-pole power switch 4 including a terminal 2.3 for connecting to the power line, a pilot lamp PL that lights up when the power switch 4 is turned on, and its stabilizing resistor R1, which is connected in parallel to the power line L. It consists of three socket pole pieces 5, 6, 7 which together constitute one socket, and a case 8 (FIG. 2) that arranges, fixes and covers these.

As shown in Fig. 1, the circuit configuration is as shown in Figure 1. When the power supply switch 4 is turned on, the pilot lamp PL
The series circuit of the stabilizing resistor R and the socket pole pieces 5, 6.7 are connected in parallel, and when the power switch 4 is turned off, the line L
The circuit connection is such that it is disconnected from the

Outlet with built-in power switch configured in this way 1
may be a recessed type that is embedded in the wall of a building or an exposed type that is attached to the outside of construction materials; for example, in the case of a three-way
Plugs for individual electric appliances can be inserted, and if the power switch 4 is turned on during the time period when these electric appliances are to be used, the desired one can be used as appropriate by turning on and off the above-mentioned electric appliances. When the power switch 4 is turned on, the pilot lamp PL lights up, indicating that it is ready for use. When the appliance is not in use, for example when the user is away in the sky or at night, the aforementioned electrical appliances are completely disconnected from the line by turning off the power switch 4, and the pilot lamp PL turns off to indicate this. There is danger from unplugged electrical appliances and the hassle of having to turn off individual appliances.

3 and 4 show other embodiments of this invention,
The power switch in Fig. 1 and Fig. 2 is overloaded.
It uses a cut-off type switch 9 and is equipped with an overcurrent cut-off mechanism K using electromagnetic force or bimetal heat deformation.Other wiring is the same as in Figure 1, and those with the same function are The same reference numerals as in FIG. 1 and FIG. 2 are used.

In this case, it can be turned on and off using the lever 10. In this case, in the event of an overload, short circuit, etc. of the connected electrical appliance, it can be automatically disconnected from the line L and the pilot lamp PL will also go out.

In each of the above embodiments, it goes without saying that the capacity of the power switch or overcurrent cutoff type switch must be large enough to simultaneously cut off the current when plugs are inserted into all sockets. Needless to say, the input capacity of the electrical appliance connected to the plug must be determined in consideration of the breaking capacity of the power switch or overcurrent cutoff switch.

As described above, according to the present invention, it is possible to cut off the communication between all the electrical appliances and lines inserted into the outlet at the outlet, and the status can be displayed by the pilot lamp, so that a person can control the lighting in the room. Although it is not often that we forget to block out phenomena that can be clearly identified with our own eyes, we can prevent the danger of being easily negligent when it comes to irons, air conditioners, and other objects that rely on the sense of touch. However, when a person leaves the room, the power outlet is often installed near the entrance of the room, so when a person leaves the room, they should turn off the power outlet at the same time as the lights are turned off to eliminate all dangers, especially after the lights are turned off at night. In order to prevent people from forgetting to turn off the switch at the outlet, if a pilot lamp is installed on the surface of the outlet that clearly indicates whether the switch is energized or cut off, it will be possible to immediately identify in the darkness if the switch is turned off even after the light has been turned off. It is considered to be even more effective.

In addition, by using an overcurrent cut-off type power switch as a power switch, in addition to the above-mentioned effects, it also functions when a current exceeding the outlet capacity is applied when the outlet is wired with multiple overlapping plugs. There is an effect.

In particular, countermeasures against overcurrents are currently being taken for each unit of power input to a house, but at present no other countermeasures have been taken. Therefore, although a large number of electrical outlets are generally installed in a house for convenience beyond the overcurrent circuit breaker installed at each incoming power unit, no safety measures are taken at each electrical outlet. This is in response to the need for safety measures especially in the outlet structure, which is a place where it is easy to damage the wiring.

This invention is not limited to the above-described embodiments, but
It is possible to carry out the present invention in modes other than the embodiments described above.
