Description

Power plug with outlet and safety cover {.}

The present invention relates to a power plug having an outlet function and a safety cover attached to the outlet, and more particularly, at least one outlet on a side of a power plug of an electrical device used in a home or office, By installing a safety cover, when not in use, it closes the safety cover to prevent short circuits and accidents, and when you want to use other electrical devices, you can open the safety cover so that you can connect to other electrical devices. And it relates to a power plug is installed a safety cover of the outlet.

Generally, the number of power outlets installed on the wall to supply electricity is limited, and in order to overcome the limited number of power outlets, power is supplied to each power supply device using multiple outlets. The supply of power using such a multi-outlet is a hassle to have to separately provide a multi-outlet, the safety cover is inserted into the unused power outlet to prevent safety accidents.

In addition, in the utility model registration (20-0171700) to increase the number of outlets without using a multi-outlet, a housing including an upper cover and a lower base, a plug terminal installed in the lower base and protruding to the outside, A through tube formed in the upper cover and formed at the above plug terminal position so that the other plug terminals can be inserted, and electrically connecting the plug terminals when the other plug terminal is inserted into the through hole; The invention has been proposed to have a connecting means installed to be connected, but the above-described design also has a problem that the safety cover must be separately inserted and installed.

Therefore, the present invention has been made to solve the above problems, by increasing the number of walls or other outlets to install one or more outlets to the power plug of the device using a plurality of power sources, other devices by the outlet In addition to supplying power, a safety cover is installed in the outlet, and when the power supply of the other equipment is not used by the outlet, the safety cover is closed to prevent a safety accident and inflow of foreign substances. In order to prevent this from happening, and to supply power to other devices, the safety cover is kept open to supply power to other devices through an outlet installed in the plug. Is to provide an installed power plug.

Accordingly, the power plug with the safety cover and the outlet provided in the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 are an exploded perspective view and a perspective view of a power plug with a safety cover and an outlet according to the present invention, respectively.

The outlet 21, 21 ′ is installed on a handle portion of the power plug, that is, a surface perpendicular to the plug terminal 40 in the plug body 30 between the power line 50 and the plug terminal 40. Then, plug terminal insertion holes 20 and 20 'for supplying power are provided.

The electricity input through the plug terminal 40 not only supplies electricity to the power line, but also the plug body 30 to supply power to another power plug through the plug terminal insertion holes 20 and 20 '. Connect in parallel. The parallel connection of the plug terminal 40 and the power line 50 or the respective outlets 21 and 21 'in the plug body 30 may be easily implemented by those skilled in the art and is not described in detail. In addition, in order to facilitate the description in the present invention is shown as a power plug having a square pillar shape is not limited or reduced the scope of the present invention by the accompanying drawings.

Each of the outlets 21 and 21 'is provided with safety covers 10 and 10', which are installed to coincide with the outer circumferential surface of the plug body 30, and torsion springs 11 to smoothly open the respective safety covers. This is laid.

When the plug terminal 40 of the power plug 1 is inserted into the outlet and coupled to or disconnected from the outlet, a protrusion 16 is formed on the outer circumference of the safety cover 10 to prevent the user from slipping.

3 is a side view of the safety cover 10 in the closed state (actual part) and the open state (embossed part), the safety cover 10 in the closed state serves as a general power plug, the safety cover ( 10) also acts as an outlet when open.

4 and 5 show a perspective view and a cross-sectional view of the safety cover 10 is coupled to the power plug 1, respectively, and FIG. 6 shows a cross-sectional view for keeping the safety cover 10 closed.

The torsion spring insertion groove 12 is formed to allow the torsion spring 11 to be inserted, and the torsion spring release preventing shaft 15 is provided to prevent the torsion spring 11 from being detached from the torsion spring insertion groove 12. It is imperative. The torsion spring 11 is coalesced in the torsion spring detachment prevention shaft 15.

In the state where the torsion spring 11 is coalesced, the cover fixing shaft 13 of the safety cover 10 is inserted into the cover fixing groove 14 to hinge-fix the safety cover.

5A shows a state where the safety cover 11 is opened by the torsion spring 11.

In addition, in order to maintain the closed state of the safety cover 11, to form a closing projection 62 on the lower side opposite the fixed hinge of the safety cover 11 and fixing projections 61 for fixing the closing projection 62 When not formed by the role of the outlet can be maintained in the closed state the safety cover (11). The fixing protrusion 61 or the closing protrusion 62 may be made of a flexible material, and the fixing protrusion 61 may be configured by a button.

The above operation is opened by the user separating the fixing protrusion 61 and the closing protrusion 62 by acupressure, and the opening groove 31 (see FIG. 3) to facilitate the opening of the safety cover 11. Form.

Figure 7 shows an installation state diagram of the power plug according to the present invention.

The outlet 200 is fixedly inserted into the wall surface 100, the power plug 1 according to the present invention is coupled. At this time, the power plug (1 ') to use another device is to maintain the safety cover 11 of the power plug (1) connected to the outlet 200 in the open state to the outlet 21 of the power plug (1) Another power plug terminal is coupled to the plug terminal insertion hole 20 to supply power.

According to the power plug provided with the outlet and the safety cover of the present invention, when one or more outlets are installed on the side of the power plug of the electric device and the safety cover is installed at the outlet, the power plug outlet is not used. Close the safety cover to prevent short circuits and safety accidents, and if you want to use other electrical devices, open the safety cover so that you can connect the power of other electrical devices. You can prevent accidents.
