BEST MODE

[0029] Hereinafter, the present invention will be described with reference to the accompanying drawings in detail. Referring to the drawings, wherein like reference characters designate like or corresponding parts throughout the several views. In the embodiments of the present invention, the publicly known functions and configurations that are judged to be able to make the purport of the present invention unnecessarily obscure will not be described.

[0030] FIG. 3 is a view illustrating an outer appearance of an electrical outlet structure according to one embodiment of the present invention. As illustrated in FIG. 3, the electrical outlet structure according to one embodiment of the present invention has four plug terminal insertion holes 110 installed in a front surface thereof.

[0031] The four plug terminal insertion holes 110 are formed by two pairs of plug terminal insertion holes 110. The user may select a pair of plug terminal insertion holes 110 installed in a diagonal direction among the four plug terminal insertion holes 110, thus to insert a plug therein.

[0032] That is, it is preferable that a distance between the pair of plug terminal insertion holes 110 installed in the diagonal direction is the same as a distance in which the plug terminals are separated, and an angle of a line connecting the pair of plug terminal insertion holes 110 is smaller than 45 degrees.

[0033] Specifically, the angle of the line connecting the pair of plug terminal insertion holes 110 is preferably about 20 to 30 degrees. By forming the angle thereof within the above range, when four electrical outlets are installed while forming a square shape as illustrated in FIG. 2, the cord of the plug inserted into the electrical outlet at the upper right side passes through a space between the electrical outlet at the lower left side and the electrical outlet at the upper left side without passing through the plug insertion hole of the electrical outlet at the lower left side, such that it may not be possible to interfere with the plug to be inserted into the adjacent electrical outlets.

[0034] FIG. 4 is a perspective view of the electrical outlet structure according to one embodiment of the present invention. Referring to FIG. 4, four plug terminal insertion holes 110 provided in the electrical outlet structure according to one embodiment of the present invention include a first terminal insertion hole 110-1, a second terminal insertion hole 110-2, a third terminal insertion hole 110-3, and a fourth terminal insertion hole 110-4.

[0035] The first terminal insertion hole 110-1 and the third terminal insertion hole 110-3 form a pair of plug terminal insertion holes 110 into which the plug terminals are inserted in a first diagonal direction, and the second terminal insertion hole 110-2 and the fourth terminal insertion hole 110-4 form a pair of plug terminal insertion holes 110 into which the plug terminals are inserted in a second diagonal direction.

[0036] A conduction member 190 is installed between the first terminal insertion hole 110-1 and the fourth terminal insertion hole 110-4 to receive power from a power supply. Therefore, the power supplied to the conduction member 190 is supplied to one terminal of the plug terminals selectively inserted into the first terminal insertion hole 110-1 or the fourth terminal insertion hole 110-4.

[0037] In addition, another conduction member 190 is also provided between the second terminal insertion hole 110-2 and the third terminal insertion hole 110-3, such that the power supplied to the conduction member 190 is supplied to the other terminal of the plug terminals selectively inserted into the second terminal insertion hole 110-2 or the third terminal insertion hole 110-3.

[0038] Meanwhile, the electrical outlet structure according to the present invention may be embedded in a building wall at the time of constructing the building, but it may be installed in such a manner that the electrical outlet body 150 in FIG. 4 is additionally inserted into the plug terminal insertion holes 110 of the electrical outlet as illustrated in FIG. 1, which has been already embedded in the wall of the building.

[0039] For this purpose, it is preferable that the electrical outlet structure according to the present invention includes a pair of coupling terminals 170 on a rear surface thereof, which are connected to a central portion of each of the conduction members 190. The pair of coupling terminals 170 are inserted into the plug terminal insertion holes 11 of the previously installed electrical outlet as illustrated in FIG. 1, and in this state, the power is supplied to the first terminal insertion hole 110-1 to the fourth terminal insertion hole 110-4 through the conduction member 190.

[0040] FIG. 5 is a view illustrating a configuration of an electrical outlet structure according to another embodiment of the present invention. Referring to FIG. 5, the electrical outlet structure according to another embodiment of the present invention further includes a blocking panel 180 which is installed on the front surface of the electrical outlet body 150 according to one embodiment of the present invention, thereby performing a function to block the four plug terminal insertion holes 110 provided in the electrical outlet body 150.

[0041] Specifically, the circular blocking panel 180 made of a non-conductive material such as plastic has a pair of plug terminal through holes 185 formed in a central portion of the blocking panel 180 flush with each other in a spaced-apart state with a predetermined interval. The blocking panel 180 is installed on the front surface of the electrical outlet body 150 through a fastening member 140.

[0042] Accordingly, the blocking panel 180 may block the four plug terminal insertion holes 110 formed in the electrical outlet body 150, and thereby, it is possible to prevent children from inserting a finger or chopstick into the plug terminal insertion hole 110, as well as prevent foreign matters from being inserted into the plug terminal insertion holes 110.

[0043] Meanwhile, a distance between the pair of spaced apart plug terminal through holes 185 should be the same as the distance between the pair of spaced apart plug terminal insertion holes 110 arranged in the diagonal direction.

[0044] In addition, to implement the present invention, the fastening member 140 is made of an elastic material such as a spring. Thereby, as illustrated in FIGS. 6 and 7, it is preferable that the electrical outlet structure allows the user to insert the plug terminals in a state in which the pair of plug terminal insertion holes 110 among the four plug terminal insertion holes 110 are exposed to an outside.

[0045] In other words, in a state in which no external force is applied by the user, the blocking panel 180 is in a normal position state illustrated in FIG. 5, and thereby, the user usually predicts that the plug terminal through holes 185 of the blocking panel 180 are located in a horizontal direction.

[0046] Therefore, the user may easily insert the plug terminals into the plug terminal through holes 185 in FIG. 5 without looking with the eyes. However, in this state, the user cannot insert the plug terminals into the plug terminal insertion holes 110 of the electrical outlet body 150.

[0047] Accordingly, the user applies a slight pressure toward the electrical outlet body 150 in a state in which the plug terminals are inserted into only the plug terminal through holes 185, and rotates the blocking panel 180 by twisting a wrist thereof in a user's desired direction as illustrated in FIGS. 6 and 7.

[0048] When the plug terminal through holes 185 come to the same position as the plug terminal insertion holes 110 of the electrical outlet body 150 as the blocking panel 180 is rotated, the plug with a slight pressure applied thereto toward the electrical outlet body 150 passes through the plug terminal through holes 185 and the plug terminal insertion holes 110 to be inserted therein.

[0049] As described above, by using the blocking panel 180 installed in a forward direction as illustrated in FIG. 5, the user may easily insert the plug into the plug terminal insertion holes 110 installed in the diagonal direction without the user having to directly check a direction in which the plug terminal insertion holes 110 of the electrical outlet body 150 are installed with eyes, as well as select an insertion direction of the plug into the electrical outlet body 150 as necessary, in consideration of a use state and a surrounding environment of other adjacent electrical outlet bodies 150.

[0050] Meanwhile, when the external force applied to the blocking panel 180 is removed by pulling the plug from the electrical outlet body 150, the blocking panel 180 is again returned to a regular position illustrated in FIG. 5 by an elastic restoring force exerted by the fastening member 140. Thereby, the electrical outlet structure waits until reuse by the user, and normally performs the blocking function of the plug terminal insertion holes 110.

[0051] FIG. 8 is a view illustrating a wiring structure in an electrical outlet structure 100 according to another embodiment of the present invention. Referring to FIG. 8, an electrical outlet body 150 in the electrical outlet structure 100 according to another embodiment of the present invention has a pair of power lines 200 installed therein. Herein, the pair of power lines 200 are located on the rear surface of the electrical outlet body 150.

[0052] Specifically, a first terminal insertion hole 110-1 and a fourth terminal insertion hole 110-4 are located on the power line 200 of a positive pole, and a second terminal insertion hole 110-2 and a third terminal insertion hole 110-3 is located on the power line 200 of a negative pole.

[0053] The power lines 200 are exposed to an upper portion of the electrical outlet body 150 through the first terminal insertion hole 110-1, the second terminal insertion hole 110-2, the third terminal insertion hole 110-3, and the fourth terminal insertion hole 110-4. Thereby, in both of a case in which the plug terminals are inserted into the first terminal insertion hole 110-1 and the third terminal insertion hole 110-3 as illustrated in FIG. 7, and a case in which the plug terminals are inserted into the second terminal insertion hole 110-2 and the fourth terminal insertion hole 110-4 as illustrated in FIG. 6, the plug terminals may receive the power through the power lines 200.

[0054] In addition, a rectangular ground wire 250 is installed on the upper surface of the electrical outlet body 150. The ground wire 250 is in electrical contact with a rectangular ground connection part 350 installed on the rear surface of the blocking panel 180 in FIGS. 9 and 10.

[0055] Specifically, as illustrated in FIGS. 9 and 10, the rectangular ground connection part 350 is installed on the rear surface of the blocking panel 180. As the blocking panel 180 in FIG. 9 is coupled to the fastening member 140 of the electrical outlet body 150 in FIG. 8, the ground wire 250 and the ground connection part 350 electrically contact with each other.

[0056] Meanwhile, in the coupled state as described above, even when the blocking panel 180 is rotated from side to side as illustrated in FIGS. 6 and 7, the ground wire 250 and the ground connection part 350 maintain the electrically connected state therebetween while maintaining the intersection state about the fastening member 140 of a fixed pin manner.

[0057] Further, as illustrated in FIG. 9, the ground connection part 350 installed on the rear surface of the blocking panel 180 has bent portions 355 formed at opposite ends thereof, which respectively protrude to the upper surface of the blocking panel 180 through ground holes 187 provided at the upper and lower portions of the blocking panel 180.

[0058] As described above, the bent portions 355 respectively protruding to the upper and lower portions on the upper surface of the blocking panel 180 contact with ground terminals (not illustrated) provided on the upper and lower sides of the plug inserted into the plug terminal through holes 185, thus to be electrically connected with each other.

[0059] Meanwhile, to implement the present invention, in order to stably couple the ground terminals provided on the sides of the plug inserted through the plug terminal through holes 185 of the blocking panel 180 with the bent portions 355 provided at the opposite ends of the ground connection part 350, and stably insert the plug therein, it is preferable that the blocking panel 180 has a cylindrical vertical panel integrally provided on an outer circumference of the blocking panel 180 to guide the insertion of the plug in a vertical direction.
