Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for extracting power from a power source to electrical equipment,
Alternatively, it relates to a device for extracting a telephone signal to a telephone.

[Conventional technology/issues to be solved by the invention] When extracting power to electrical equipment, generally a power outlet is fixed to the wall of the room, and a power outlet is connected to the end of the cord connected to the electrical equipment. It is well known that the electrical appliances are installed in a place where the electrical equipment is installed far from the electrical outlet. If the power outlet is hidden by furniture, etc., a long cord must be used, which may cause problems such as poor appearance or tripping over the power outlet.

Therefore, Japanese Utility Model Publication No. 59-35980 as a prior art discloses that two grooves into which the contact terminals of the plug are fitted are formed in a rod-shaped channel member made of an insulator in parallel along the longitudinal direction of the channel member. By providing a conductor along the length of these two grooves with which the contact terminal of the inserted plug comes into contact, it is possible to extract electric power from any position along the length of the channel member. We are proposing a device.

However, in this prior art, the groove for inserting the contact terminal of the plug is exposed to the outside, so there is a possibility that the groove may become clogged with dirt and cause a current leakage, or a person may insert a piece of metal into the groove. There was a risk of electric shock if the plug was inserted into the socket, which posed a safety problem.

SUMMARY OF THE INVENTION An object of the present invention is to provide a device that can input and output power and the like over a wide range without reducing safety.

[Means to solve the problem]

In order to achieve this object, in the present invention, an insulating part made of a soft insulator through which a pointed contact terminal of a power connection device can be pierced is formed over an appropriate range on the surface side of an article such as furniture, and the insulating part A conductive layer through which the contact terminal of the connector can be pierced is provided within the thickness of the connector.

[Action/effect of the invention]

With this configuration, the contact terminal of the connecting tool is inserted into the insulating part formed on the article such as furniture from the surface direction of the article, and the contact terminal of the connecting tool and the conductive layer are electrically connected, thereby providing conductivity to the conductive layer. Since it is possible to take out electrical power, telephone signals, etc. to the outside of the article, or input power, etc. to the conductive layer, by forming an insulating part over an appropriate range on the surface side of the article, it is possible to use a wide area. This means that input and output of power, etc. can be performed at any location throughout the area.

Since the conductive layer is covered with a soft insulator, there is no risk of electrical leakage when objects touch it, or electric shock when people touch it, ensuring safety.

Therefore, according to the present invention, it is possible to input and output power and the like over a wide range without reducing safety.
