Description

Multi-stage prefabricated outlet

The present invention relates to a multi-stage receptacle, and more particularly, to a multi-stage receptacle, which can be connected to an outlet made of two or three plugs and connected to four, six or eight bulbs, The present invention relates to a multi-stage prefabricated outlet that can be connected to a power outlet to use the outlet.

The outlet is used as a means of connecting electric power when using various appliances such as a home, a factory, etc., which is used as an electric power source. Various types are available on the market. If you look at some of them, it is necessary to add a standardized outlet and a connection port that can be bound only in the number of connection ports, such as 2, 3 or 4, And an auxiliary socket having a grounding contact portion on one of the other three surfaces.

In the case of the conventional standardized socket outlet having the above-described structure, the number of the plugs to be connected is limited, and in case of using more electric appliances, a separate socket must be additionally used.

In this case, it is common to use the above-described auxiliary outlet. In order to use the auxiliary outlet, it is necessary to insert the auxiliary outlet into the upper surface of the standardized socket outlet so that the socket is unexpectedly protruded, And the auxiliary socket is simply plugged into the connection port. If one of the plugs is pulled because of a weak coupling force, the auxiliary socket is pulled out, so that there is a problem that a general user can not exclude the danger of electric shock.

As a prior art for solving the above-mentioned problems, a "multi-stage assembly type receptacle" of Registration No. 20-258679 (published on Dec. 28, 2001) is a general type of plug socket having a connection port such as two, three or four, A receptacle structure comprising: a receptacle having a connection fitting on one side of the receptacle; Wherein the auxiliary grounding protrusion is provided on one side of the main body and the auxiliary grounding receptacle is provided on the opposite side of the auxiliary grounding protrusion so that the grounding protrusion is inserted into the main body of the main body, So that other auxiliary outlets can be used continuously.

In the prior art constructed as described above, a connection plate for fixing the auxiliary socket in a state that the auxiliary socket is connected to the socket is configured to be coupled at one-touch. However, the configuration is not clear, There is a problem in that it is not possible to confirm the state of the one-touch coupling because the configuration is not shown, and it is not easy to separate the outlet from the outlet when using an adhesive.

In addition, in the prior art, when the connection is made using a connection plate without using an adhesive, there is a problem that the outlet and the outlet are not properly connected and are separated.

In addition, since the electric wire or connection terminal other than the auxiliary outlet can not be used in combination with the outlet, there is a problem that the expandability is low.
