Definitions

  • a receptacle which is adapted to be connected to a plug provided with a plug pin protruding from a plug body
  • the receptacle including: a receptacle unit having a plug insertion surface in which an insertion port is formed and a pin receiver for gripping the plug pin inserted into the insertion port; and a supporting body protruding from the receptacle unit, wherein the supporting body is provided with a restricting part formed in a supporting surface facing to the plug body, the restricting part being in contact with a protruding part formed on the plug body when the plug is connected to the receptacle, so that the restricting part restricts a movement of the plug body in an orthogonal direction perpendicular to an insertion direction of the plug pin within a plane extending along the supporting surface, and guides a position of the plug body relative to the receptacle unit so as to align the plug pin to the insertion port.
  • the restricting part is formed in the recessed portion, the position of the plug relative to the receptacle can be fixed only by providing a simple structure in the supporting body. Further, the slope portion formed in the recessed portion enables the protruding part to climb and pass over the recess easily. Accordingly, it becomes easy for the protruding part to move from the restricting part toward the surface of the supporting body.
  • the position corresponding to the restricting part on the decorative cover may often be in contact with the plug pin.
  • the decorative cover may be damaged and deteriorated.
  • the protecting member is provided at the above position, the damage of the decorative cover due to the plug pin can be reduced.
  • Fig.15 is a perspective view showing a state where the plug is in contact with the receptacle of the same embodiment
  • a plane 84a extending along the front-rear direction X and the left-right direction Y is provided.
  • a plane 84b (see Fig.3B) similar to the plane 84a and a slope 84c tilting upwardly as it goes rearward are provided.
  • the slope 84c is formed to have a tilting angle smaller than those of the front slope face 85a and the side slope faces 85b.
  • the bottom end surface 52 of the decorative cover 6 is formed to surround the recess 73.
  • the waterproof receptacle in accordance with the present embodiment is known in that the insertion ports are opened downwardly for the purpose of preventing rainwater from infiltrating into the insertion ports.
  • a user can hardly recognize visually the insertion ports, which makes it difficult to connect a plug to the receptacle.
  • the present embodiment is configured to insert the tip end 91bl of the ground plug pin 91b into the ground-pin insertion port 75b in the state where the protruding part 94 is accommodated in the restricting part 87. Accordingly, since the protruding part 94 is accommodated in the restricting part 87, the position of the plug pins 91 relative to the insertion ports 75 can be fixed, in addition to fixing the position of the plug B relative to the insertion ports 75 in the left-right direction Y. As a result, the user can connect the plug B to the receptacle A more easily and steadily.
  • the present embodiment is configured to have the side slope faces 85b in the joint portion 85. According to such structure, the protruding part 94 is guided into the bottom 84 by being in contact with the side slope faces 85b, even if the protruding part 94 of the plug body 90 is misaligned with the bottom 84 of the restricting part 87 in the left-right direction Y. Accordingly, the protruding part 94 can be accommodated easily in the restricting part 87.
  • the present embodiment is configured to protrude the base 80 more forwardly and laterally from the side wall portion 50. Accordingly, the door body 7 can be opened from the closed position in such a way that the protruding portion of the door body 7 is hooked by the plug body 90 or a user's finger.
  • a joint wall 89a joining rear ends of slope portions 89 in the left-right direction Y.
  • the joint wall 89a forms a wall extending along the left-right direction Y and the up-down direction Z.
  • the present embodiment is configured to omit the partition wall 86. Therefore, the water infiltrating into the gap between the decorative cover 6 and the base 80, as shown by arrows in Fig . 11 , passes both sides of the slope portions 89 in the left-right direction Y, and infiltrates into the fixing part 88. After that, the water drips downwardly through the gap between the base 80 and the shaft body 9. Accordingly, the water is prevented from remaining in the restricting part 87.
  • the present embodiment as shown in Fig .15 , has the protective plate 17 in the position corresponding to the restricting part 87. Accordingly, when the plug B moves the door body 7 to the opened position, the plug pins 91 of the plug B come into contact with the protective plate 17. Thus, the plug pins 91 are prevented from being in contact with the decorative cover 6.
  • a waterproof packing 19 is attached at the rear side of the spacer 18.
  • the waterproof packing 19 is also in contact with a surface of a wall WL.
  • an electric wire of which a conductor diameter is less than or equal to 2 mm (a first electric wire) can be bent by an operator ' s hand to be accommodated in the receptacle A.
  • An electric wire of which a conductor diameter is more than or equal to 2.6 mm (a second electric wire) , however, can hardly be bent by an operator's hand to be accommodated in the receptacle A.
  • the operator connects the second electric wire to the receptacle A with no bending of the second electric wire.
  • the receptacle A is directly attached to the surface of the wall WL, however, it is difficult to accommodate the second electric wire in the receptacle A since there is no space in the front-rear direction X for accommodating the second electric wire.
  • a receptacle with no indicator 54 is hard to check directly whether or not electric power is supplied to the receptacle A. Therefore, in such a receptacle with no indicator 54, a user can check the ON or OFF-state of the receptacle by confirming whether or not electric power is supplied to apparatus connected to the plug B (see Fig. 6) when the plug B is connected to the receptacle. Accordingly, after connecting the plug B, the user knows that it is needed to set the ON-state of the receptacle through the switch, a control panel or the like in the house. As a result, the receptacle has poor operability .
  • the third embodiment is provided with the protective plate 17 as a separate member from the decorative cover 6, the structure of the protective plate 17 is not limited thereto.
  • One portion with higher hardness than that of the other portions of the decorative cover 6 may be formed on an area to be in contact with the plug pins 91 when the plug B is inserted into the receptacle.
  • scratch resistance coatings such as UV coating, which are cured and dried by radiating ultraviolet rays to the decorative cover 6, may be used as a protective material.
  • the above area of the decorative cover 6 may be molded of a synthetic resin having higher hardness than that the other areas of the decorative cover 6 by double-shot molding.
  • a sixth embodiment will be described with reference to Figs . 26 and 27.
  • the receptacle and the plug of the present invention are exemplified as a waterproof receptacle attached to an outer wall of a house and a plug to be inserted into the waterproof receptacle.
  • the present embodiment is different from the above embodiments in that a supporting body for supporting the plug body 90 is fixed to the receptacle unit 1A so as not to pivot, instead of the door body 7 provided pivotally.
  • a supporting body for supporting the plug body 90 is fixed to the receptacle unit 1A so as not to pivot, instead of the door body 7 provided pivotally.
  • a supporting body 607 as shown in Fig. 28 may be adopted instead of the supporting body 507.
  • the supporting body 607 has a structure approximately similar to that of the door body 7 as shown in Fig. 21.
  • a restricting part 687 includes a pair of ribs 610 protruding upwardly from a base 680 of a supporting body 607, and a fixing part 688 includes a recess formed so as to be separated rearwardly from the restricting part 687.
  • the ribs 610 are formed to have a rectangular parallelepiped shape whose long side extends in the plug pin insertion direction.
  • the stand body 1012 is provided with a recess 1015 at a portion corresponding to the door 1013.
