Description

Multi ground outlet {MULTI GROUNDIMG OUTLET}

The present disclosure relates to a multi-outlet that can be used by inserting a plurality of power plugs, and more particularly, to a multi-ground outlet in which a ground pin is formed between each connection protrusion.

Unless otherwise indicated herein, the content described in this section is not prior art to the claims of this application and is not admitted to be prior art by inclusion in this section.

In general, an outlet is a device that allows electricity through a plug provided in an electric appliance and is used to transmit electric power in various places such as a home, an office, or an industrial site.

These outlets are mainly provided with only two inserts, so they are usually embedded and used in architectural walls such as homes and offices. Recently, a multi-outlet has been used to transmit power to remote electric appliances.

That is, an outlet made of an extension wire of a predetermined length has been developed, and a multi-outlet, that is, a multi-outlet, in which two or more insertion holes are formed to connect a plurality of electrical appliances, has also been developed.

Here, as a technical document for a conventional outlet, Korean Utility Model Publication No. 20-2018-0003211 has been disclosed.

Looking at the connection structure of the ground terminal for the conventional outlet, the outlet body provided at the bottom, the connection terminal seated on the upper portion of the outlet body, the ground terminal connected to the upper surface of the connection terminal, and the upper portion of the outlet body It is composed of a cover outlet cover, and the connection terminal is composed of a base terminal seated on the outlet body and connected to the ground, and a connection terminal connected to the upper surface of the base terminal and connected to the ground terminal.

At this time, the connection structure of the ground terminal to the conventional outlet forms a contact surface bent downward from one surface of the base terminal to connect the base terminal and the connection terminal,

Interconnection was performed by forming a contact hole bent in a downward direction so as to contact the contact surface on one surface of the connection terminal.

However, the connection structure of the ground terminal to the conventional outlet has a problem that the contact portion is easily separated by bending the contact surface or the contact hole in one direction when an external shock occurs.

In addition, the connection structure of the ground terminal to the conventional outlet has a problem that the foreign matter is introduced between the contact surface or the contact hole when the foreign material is introduced from the outside to lose the grounding function.

The outlet is an electrical material to which the plug is connected, and is provided with a ground terminal electrically connected to the earth terminal in consideration of electrical stability.

In addition, since the earth terminal and the ground terminal must be fixed so that they cannot be arbitrarily separated by law, it can be assembled by a rivet joint method or a soldering method that requires a separate rivet. Various connection structures have been proposed.

For example, in the Republic of Korea Utility Model Registration No. 20-0428109, an insertion hole in which a seating hole is formed on one side of a ground terminal and an earth terminal is formed, and a space between left and right side walls on the other side of the ground terminal and the earth terminal. It is characterized in that the additionally provided locking jaw protrudes, and a protrusion is formed to protrude downwardly inside the insertion hole, a support hole is formed on a supporting plate inside the locking jaw, and a supporting jaw is formed to protrude downwardly inside the protrusion. Grounding terminal connection structure of 220 volt outlet is proposed.

However, the grounding terminal connection structure according to the registered utility model No. 20-0428109 is a method of assembling the earthing terminal by inserting and rotating the earthing terminal, which is difficult to assemble, takes a lot of time, and is assembled by the fitting method. There is a problem in that connection failure occurs.

In addition, the grounding terminal and the earthing terminal have a disadvantage in that they are difficult to manufacture and assemble because the structure of the connection portion is complicated and there are many components.

In particular, the earth terminal has a disadvantage that it is difficult to manufacture and there is a high risk of defects due to the need for two bending processes along with a punching operation to form a locking jaw.

As a result, the grounding terminal connection structure according to the registration utility model No. 20-0428109 described above leads to a lack of safety and a decrease in productability due to a defective connection, and productivity is reduced due to a lack of assembly and an increase in assembly time due to structural complexity. There is a limit to falling and increasing production cost.

Republic of Korea Utility Model Publication No. 20-2018-0003211
