Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multiple outlet, and in particular, in a kind of modularized base, a plurality of conductive pieces of a power supply unit are combined at appropriate positions so that an insertion connection structure constituted by the conductive pieces is formed. A switch unit that has multi-directional selectivity and is provided separately,
The present invention relates to a multiple outlet of a contact type power supply unit that can effectively reduce the volume of the power supply unit because parts such as a power indicator light and a protective cover are compatible with multiple sources.

[0002]

2. Description of the Related Art So-called external power supply units are often found in extension cord outlets. A general extension cord outlet is a pair or more expansion type outlets, and its basic form is a design in which multiple sets of insertion holes are installed on the outlet body and corresponding switch units can be combined to form a continuous switch outlet. There is.

A large number of sets of insertion hole base modules are installed on the main body of the outlet, and one set of switch units corresponds to each insertion hole base module. In a certain type of the switch unit, a power indicator light is attached to the inside of the switch button body. Further, the switch body has an overload protection function, and the switch unit controls the conduction of the power of the corresponding insertion hole base.

The above-mentioned conventional component of the extension type cord switch outlet is convenient, and the insertion hole base module and the switch unit which are molded independently are used. As a result, it is directly incorporated into the outlet body. In addition, in the outlet main body, a conductive piece in the form of a series of fire wire and ground and parallel connection is attached, and the insertion hole base module and the conductive contact of the switch unit are connected to each other.

[0005] However, although the independently molded insertion hole base module and the switch unit are advantageous for assembling into the outlet main body, there are many limitations in this type. First, the insertion hole base module and the switch unit each have a considerable volume, and the outlet main body requires a certain volume because they are incorporated. Therefore, miniaturization is difficult.

Next, since the switch unit is a standard product in a fixed form, when the power indicator lamp or the overload protector is installed, the arrangement of the conductive line has no room for change due to the specified model. Therefore, it is difficult to design the outlet main body and the insertion hole base module in an advantageous manner, and the entire outlet product cannot be removed from the conventional type. In other words, the conventional products are similar to each other, and cannot be said to have market competitiveness.

[0007]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to use a modularized base and to combine a plurality of conductive pieces of a power supply unit at appropriate positions so that the conductive pieces form an insert. The connection structure has multi-directional selectivity, and since the separately installed parts such as the switch unit, the power supply indicator light and the protective cover are compatible with multiple elements, the volume of the power supply unit can be effectively reduced. To provide.
