 Power supply connecting device

The present invention relates to a power supply connection mechanism, and more particularly, to improve the connection structure of an outlet connected to an electrical wiring to supply current, and a plug electrically connected to the outlet to supply power to the electrical appliance. It is possible to insert or unplug the plug into the outlet with light hand movement without force, and especially when the electric appliance is not in use, simply disconnect the plug from the outlet to keep the power disconnected. The present invention relates to a power connection device that can prevent electric fires caused by damage or overcurrent of electric devices, and in particular, reduce energy costs by cutting off the consumption of standby power.

Generally, a plug is a connector having a pin designed to plug into the socket of a socket outlet for electrical connection and mechanical maintenance of a flexible wire, and the outlet is a knife designed to plug into the pin of the plug. It is a connecting mechanism that has a support and a terminal for cable connection.

The plug is a rewirable plug having a structure capable of replacing a flexible cable and a non rewirable plug having a structure in which the accessory manufacturer connects with the flexible cable to form a complete unit assembled. ).

The outlet may include a fixed socket outlet connected to a fixed wiring, a portable socket outlet connected to or integrally formed with a flexible cable and easily moved to another place even when the power supply is connected, and two or more outlets. There are various types of outlets, such as multiple socket outlets assembled and socket outlets for appliances assembled or fixed to electrical appliances.

As a conventional technology for a power connection device such as a conventional plug or outlet having a variety of forms as described in the Republic of Korea Patent Publication No. 10-1998-068135 "grounding structure of the plug", Korea Patent Office registered patent registration number No. 10-0573088 "Ground plug device", Republic of Korea Patent Office Publication No. 10-0682737 "grounding structure of the plug" and the like has been presented.

In addition, Republic of Korea Patent Office Utility Model Registration No. 20-0332287 "Ground terminal connection structure of the grounding socket for 220 volts", and Republic of Korea Patent Office Registration Utility Model Publication No. 20-0331540 "Ground terminal connection structure for the 220V outlet ", Republic of Korea Patent Office registered Patent Publication No. 10-0939189" safety device for outlet "and the like has been presented.

The conventional connection structure of the conventional plug and an outlet is to insert two pins protruding out of the plug into an insertion hole drilled into the bottom of the socket hole of the outlet so as to be electrically connected to the connection terminal provided inside the outlet. It will supply power to various electric appliances.

In addition, a safety device is provided inside two insertion holes drilled in the outlet to prevent an electric shock that may occur due to the insertion of a conductor such as a metal rod.

On the other hand, the grounding of the plug and the outlet is made together with the connection process of the plug and the outlet, and the grounding terminal exposed or protruding to the outer peripheral surface of the plug is connected to the grounding terminal protruding or protruding to the inner peripheral surface of the socket hole of the plug. The protective ground is completed to prevent electrical accidents such as electric shock.

However, when the plug is plugged into the outlet in a dark and narrow space, the power connector such as the conventional plug and outlet is difficult to fit the pin-type connection terminal protruding from the plug into the insertion hole drilled into the socket hole of the outlet. After fitting the connection terminal of the plug to the insertion hole, there was an inconvenience of inserting it with a lot of force so that the connection terminal of the plug can be fitted to the connection terminal of the outlet.

And when pulling out the plug of the plug that is forcibly fitted to the plug of the outlet, the hassle of pushing the front of the outlet with one hand and pulling the plug with the other hand is the same as when inserting the plug into the outlet. there was.

As a prior art for improving the problems with the power connection mechanisms such as the above-described conventional plugs and outlets, Korean Patent Office Publication No. 10-2006-0083031 "Magnetic contact electric plug outlet device" and the Republic of Korea Patent Office registered Patent Application Publication No. 10-0609659, "Attached Power Connection Mechanism" (hereinafter referred to as 'quotation invention 1') has been presented.

The "attachable power connection mechanism" of the above-cited invention 1 constitutes two connection terminals protruding from the plug in the shape of a circle having a different radius, so that when the plug is inserted into the outlet, it is not necessary to find the insertion hole of the outlet. Its main purpose is to make it easy to insert the plug into the outlet by attaching and fixing a magnet in the shape of a circle with opposite polarity to the outlet and the outside of the plug. It is an automatic power on / off device of the outlet which allows the power to be conducted through the outlet terminal only when the plug is connected to the outlet to prevent the electric safety accident in advance.
