  The present invention relates to a power plug receiving structure, and more particularly to a power plug receiving structure that ensures safety by preventing inadvertent insertion of foreign matter.

  At present, many electric products are used in the home, and many power plug receptacles are also being used. Sophisticated electrification makes life of modern people very convenient, but there is also a risk that the danger is relatively increased. In particular, young children have a risk of electric shock by inserting a foreign object into the power plug receptacle with curiosity.

  In order to use electricity safely, it was necessary to prevent an electric shock by inadvertently touching the power plug receptacle. In the conventional safety plug, the electrode connected to the power source is covered with a cover or a movable member. However, in order to insert the plug into the power plug receptacle, the insertion hole of the power plug receptacle is accurately opened. There was a need.

The conventional safety plug can arbitrarily prevent the plug from being inserted into the power supply insertion hole. However, when one insertion hole is opened, the other insertion hole is also opened at the same time. May have a foreign object in hand and may be inserted into the insertion hole, which is not safe.
When the two insertion holes of the power plug receptacle are opened simultaneously, two electrodes of a general household power plug receptacle have one electrode connected to a live wire and the other electrode connected to a ground wire (both neutral wire) Therefore, it was very dangerous if foreign matter was inadvertently inserted into the electrode connected to the live wire.

The first electrode 12 and the second electrode 13 are covered.

Reference is made to FIGS. 4, 5A and 5B. FIG. 4 is a partial cross-sectional perspective view when an insertion plug is inserted into a power plug receiving structure according to an embodiment of the present invention. FIG. 5A is a cross-sectional view of a power plug receiving structure according to an embodiment of the present invention when the plug is inserted in a normal state. FIG. 5B is a cross-sectional view of the power plug receiving structure according to the embodiment of the present invention when the plug is inserted in a normal state.
As shown in FIGS. 4, 5 </ b> A, and 5 </ b> B, the first slope 311 of the safety gate body 31 of the present embodiment has a step formed in the sliding direction of the safety gate body 31. Specifically, in the safety gate body 31 in the normal position, one of the first slope 311 and the first perforation 313 contacts one of at least two blades 51 and 52 of the plug-in plug 5. The part is exposed.

  5A and 5B, the position of the first inclined surface 311 of the power plug receiving structure according to the embodiment of the present invention corresponds to the first insertion hole 21, and the position of the first perforation 313 is , Corresponding to the second insertion hole 22. When the plug 5 is accurately inserted into the power plug receiving structure, at least two blades 51 and 52 of the plug 5 are simultaneously brought into contact with the first inclined surface 311 and the first perforation 313 of the safety gate body 31; The safety gate body 31 is held in a balanced state by the pressing force of the at least two blades 51, 52 of the plug 5. First, one of the at least two blades 51, 52 of the plug 5 is The plug 5 is continuously inserted toward the power plug receiving structure in contact with the first inclined surface 311. Then, the safety gate body 31 is pushed through the first inclined surface 311, the rolling element 32 rolls toward the guide groove 112, and the rolling element 32 is accommodated via the inclined portion 1121 of the guide groove 112. Rolls up to the portion 1122 and is positioned in the housing portion 1122. Then, the top surface of the safety gate body 31 moves away from the bottom surface of the top cover 2, moves toward the normal position, and moves until the first perforation 313 of the safety gate body 31 comes into contact with another blade. The at least two blades 51 and 52 of the plug 5 push the first inclined surface 311 and the first perforation 313, respectively, to move the safety gate body 31 away from the normal position.

  The position of the second slope 312 of the safety gate body 31 is a position corresponding to the left slope 23 of the top cover 2. A protruding end 314 is formed at a location adjacent to the first slope 311 and the second slope 312 of the safety gate body 31. The protruding end 314 slides on the left slope 23, and when the safety gate body 31 is pushed to the use position, the position near the fulcrum 25 on the left slope 23 stops the movement of the protruding end 314, The safety gate body 31 remains in the use position.

  As shown in FIG. 6A, in the power plug receiving structure according to an embodiment of the present invention, only the first blade 51 of the plug 5 is inserted into the first insertion hole 21 and is in contact with the first inclined surface 311. Then, one end of the first inclined surface 311 receives a downward pressure, and one end of the first perforation 313 repels, so that the first blade 51 is inserted into the first insertion hole 21 downward. Disappear. Therefore, the safety gate body 31 is not inserted into the first through-hole 113 and the second through-hole 114, and is not brought into contact with the first electrode 12 and the second electrode 13, so that foreign matter is present in the first electrode 12. Can be prevented from touching.

  As shown in FIG. 6B, in the power plug receiving structure according to an embodiment of the present invention, only the second blade 52 of the plug 5 is inserted into the second insertion hole 22, and the first perforation 313 and When contacted, one end of the first perforation 313 receives downward pressure, and when one end of the first inclined surface 311 repels, the projecting end 314 is engaged in the first insertion hole 21. Since the second blade 52 is not continuously inserted downward into the second insertion hole 22, the safety gate body 31 is also not inserted into the first through hole 113 and the second through hole 114. . For this reason, the first electrode 12 and the second electrode 13 are not brought into contact with each other, and foreign matter can be prevented from coming into contact with the first electrode 12.

  The rolling element 32 described above may be a sphere, a metal sphere, a sphere, a metal sphere, or the like.

  As can be seen from the above, the power plug receiving structure of the present invention has the following advantages over the prior art. When inserted into any one of the first insertion hole and the second insertion hole, the safety gate swings around the rolling element and continuously covers the first electrode and the second electrode. Keep holding. If the insertion plug is not inserted correctly, the safety gate cannot be pushed from the normal position to the use position by the first slope, so that foreign matter is prevented from being inserted into the power plug receiving structure. Can do.

  The preferred embodiments of the present invention have been disclosed as described above so that those skilled in the art can understand them, but these do not limit the present invention in any way. Various changes and modifications can be made without departing from the spirit and scope of the present invention. Accordingly, the scope of the utility model registration claim of the present invention should be broadly interpreted including such changes and modifications.
