Description

  The present invention relates to a door outlet having a door for preventing electric shock.

  Conventionally, in order to prevent an electric shock caused by touching a charging part such as an internal blade receiving part, an outlet with a door provided with a door body that closes a plug blade insertion hole when a plug is not connected has been provided. For example, it is disclosed in Patent Document 1. Hereinafter, a conventional example of this type of outlet with door will be described with reference to the drawings. In the following description, the vertical direction in FIG. 13A is defined as the vertical direction.

  In this conventional example, as shown in FIGS. 13A and 13B, plug blade insertion holes 20 to 22 into which plug blades of a three-pole plug (not shown) having a ground electrode are inserted are inserted. The housing 1 having the portion 2 and the pair of blades of the voltage electrode of the three-pole plug inserted in the blade insertion holes 20 to 22 and the plug blade of the ground electrode are connected in contact with each other. Blade receiving portion 6 (the blade receiving portion corresponding to the voltage electrode is not shown). The housing 1 is formed by abutting each opening of a long box-shaped body 10 whose upper surface is open and a long box-shaped cover 11 whose lower surface is open, and each blade receiving portion 6 is housed inside the body 10. The The body 10 and the cover 11 are joined by attaching a pair of substantially rectangular holding plates 12 to both side surfaces along the longitudinal direction of the housing 1 in a state where the body 10 and the cover 11 are abutted. It has become.

  The plug-in part 2 has plugs 20 and 21 for voltage electrodes into which a pair of plug blades for a voltage electrode of a three-pole plug are inserted, and a plug for a ground electrode into which a plug blade for a ground electrode of a three-pole plug is inserted. The blade insertion hole 22 is formed as one set, and two sets are provided on the upper surface of the cover 11 along the longitudinal direction. The voltage electrode plug blade insertion holes 20 and 21 are respectively flat blade plug insertion holes 20a and 21a into which flat plug blades are inserted and round pin type blade insertion holes 20b into which round pin type blades are inserted. , 21b form one plug blade insertion hole. In addition, the plug blade insertion hole 22 of the ground electrode is formed in a shape into which a round pin type plug blade is inserted.

  As shown in FIG. 13 (b), between each insertion part 2 and the blade receiving part 6, there is a plug blade between the position where the plug blade insertion holes 20, 21 of the voltage electrode are opened and closed. Two door bodies 3 that are slidable in a direction (longitudinal direction of the housing 1) intersecting with the insertion direction are respectively provided. The door body 3 is disposed such that the wing pieces 30 and 31 projecting on both sides thereof face the plug blade insertion holes 20 and 21 of the voltage electrode, and one end portion is provided at an intermediate portion 32 of the wing pieces 30 and 31. A coiled spring member 5 that is attached to the door body 3 and urges the door body 3 so that the other end is attached to the housing 1 and moves to a position that closes the plug blade insertion holes 20 and 21 of the voltage electrode. Is attached. Further, the contact surfaces of the blade blades 30 and 31 with the plug blade are inclined with respect to the insertion direction of the plug blade, and the contact surface is pressed when the plug blade is inserted and connected to the insertion direction of the plug blade. It slides in the intersecting direction.

  For this reason, when a plug blade of a three-pole plug is inserted and connected to the insertion portion 2, the door body is in a position where the plug blade is brought into contact with the door body 3 and the plug blade insertion holes 20, 21 of the voltage electrode are opened. 3 is slid and can be inserted and connected to the respective blade insertion holes 20 to 22, and when the plug blade of the three-pole plug is not inserted and connected, the door body 3 is attached to the spring member 5. Since it moves to a position for closing the plug blade insertion holes 20 and 21 of the voltage electrode by elastic force, it is possible to prevent an electric shock by preventing the charging portion such as the blade receiving portion 6 inside the housing 1 from being touched from the outside. .

Further, in this conventional example, the door body 3 is disposed so as to be swingable in the insertion direction of the plug blade around the intermediate portion 32 of both wing pieces 30 and 31, and the swinging and tilting door body 3 is a housing. The sliding movement of the door body 3 is prevented by contacting the inner wall of the body 1. For this reason, for example, when an object is inserted only into the plug blade insertion hole 20 or 21 of one of the voltage electrodes due to a child's mischief or the like, one of the blade pieces 30 and 31 is plugged into the plug blade of the other voltage electrode. If the door 3 is slid to move toward the insertion holes 20, 21, the inner wall of the housing 1 and the inclined blades 30, 31 come into contact with each other and are prevented from moving. It is possible to prevent electric shock by preventing the charging part such as the blade receiving part 6 from being touched.

  However, although the conventional example has means for returning the door body 3 to the position where the plug blade insertion holes 20 and 21 of the voltage electrode are closed, it has means for returning the swinging and inclined door body 3. Therefore, when an object is inserted only into the plug blade insertion holes 20 and 21 of one of the voltage electrodes in the insertion portion 2, the door body 3 is inclined toward the plug blade insertion holes 20 and 21 of the other voltage electrode. The state continues and does not return to the original state. For this reason, if the plug blade of the three-pole plug is inserted while the door body 3 is tilted, the door body 3 does not slide smoothly depending on how it is inserted. When trying to insert the plug blade of the three-pole plug, the door body 3 may be deformed or damaged.

  The present invention has been made in view of the above points, and has a door that can return the door body to its original state even if an object is inserted only into one of the plug blade insertion holes of the insertion portion. The purpose is to provide an outlet.

  According to the eighth aspect of the present invention, the middle frame can be fixed to the cover by latching the latching protrusion of the cover with the latched portion of the middle frame. Therefore, since the cover and the middle frame can be handled integrally while preventing the parts such as the door body housed between the cover and the middle frame from falling off, the workability during assembly can be improved.

  Hereinafter, an embodiment of an outlet with a door concerning the present invention is described using a drawing. However, since the basic configuration of this embodiment is the same as that of the conventional example, common portions are denoted by the same reference numerals and description thereof is omitted. Further, in the following description, the top and bottom in FIG.

  In this embodiment, as shown in FIGS. 1 and 13 (a), a pair of plug blades (not shown) of a voltage pole of a three-pole plug (not shown) having a ground pole and a plug blade ( A casing 1 having two sets of insertion portions 2 in which three plug blade insertion holes 20 to 22 into which a plug is inserted is inserted, and the blade insertion holes 20 to 20 housed in the casing 1. A pair of plug blades of a voltage pole of a three-pole plug inserted into the blade 22 and a plug blade of a ground electrode, and a plug receiving portion 6 and a blade receiving portion 6 in the housing 1. A door body 3 that is slidable in a direction (front-rear direction) that intersects the insertion direction of the plug blade between a position at which the plug blade insertion holes 20 and 21 of the voltage electrode are opened and a position at which it is closed; Two coil-shaped spring members 5 having one end attached to the door 3 and the other end attached to the housing 1 are provided.

  The blade receiving portion 6 corresponding to the voltage pole includes a pair of spring pieces 60 opposed to each other, a spring piece 61 opposed to one side surface of both the spring pieces 60, and a connecting piece that continuously couples the spring pieces 60 and 61 together. A pair of spring pieces 60 that are elastically contacted with a round pin type plug blade by a pair of spring pieces 60 that face each other, and a pair of spring pieces that face the plate surface of the spring piece 61 and the spring piece 61. A blade receiving portion that elastically contacts the flat stopper blade at the end face of 60 is configured. The blade receiving portion 6 corresponding to the grounding electrode is constituted by a pair of spring pieces 60 facing each other and a connecting piece for continuously connecting the spring pieces 60 together, since a flat plug blade is not inserted. The blade receiving portion 6 corresponding to the voltage electrode is disposed at a position facing the plug blade insertion holes 20 and 21 of the voltage electrode, and the blade receiving portion 6 corresponding to the ground electrode is connected to the plug blade insertion hole 22 of the ground electrode. It arrange | positions in the position which opposes.

  As shown in FIG. 3, the door body 3 is positioned between the pair of wing pieces 30, 31 and the wing pieces 30, 31 disposed in a shape facing the plug blade insertion holes 20, 21. It consists of an intermediate part 32 connecting the blade pieces 30, 31. Inclined surfaces 30a and 31a that are inclined with respect to the insertion direction of the plug blades are formed on the upper surfaces of the blade pieces 30 and 31, respectively, and the inclined surfaces 30a and 31a receive the pressing force of the plug blades, thereby opening the door body. 3 slides in the front-rear direction.

  Mounting protrusions 30c and 31c into which one end of the spring member 5 is press-fitted are provided on one side surfaces of the blade pieces 30 and 31, respectively. In addition, peripheral walls 30d and 31d that cover one end of the spring member 5 are provided upright around the mounting protrusions 30c and 31c. Thus, the peripheral members 30d and 31d prevent the spring member 5 from falling off because the spring member 5 is twisted when the door body 3 swings and tilts.

  Below the door body 3 and the spring member 5, an inner frame 4 is provided for sandwiching and holding the door body 3 and the spring member 5 with the cover 11. As shown in FIG. 4B, the middle frame 4 is formed in a substantially rectangular shape so as to cover the door body 3 and the spring member 5, and at the position facing the plug blade insertion holes 20, 21 of the voltage electrode, A substantially rectangular window hole 4c is provided to allow the plug blade insertion holes 20 and 21 of the voltage electrode and the blade receiving portion 6 to communicate with each other. In addition, a cutout is provided at a position facing the plug blade insertion hole 22 of the ground electrode in order to allow the plug blade insertion hole 22 of the ground electrode and the blade receiving portion 6 to communicate with each other. As shown in FIG. 6, a protrusion 4 d that protrudes downward along the front-rear direction is formed on the lower surface of the middle frame 4. Thus, the middle frame 4 is disposed inside the housing 1 by fitting the protrusions 4d into the recesses 10a provided along the front-rear direction inside the body 10.

  A pair of lid portions 4b for closing the opening of the guide portion 11b of the cover 11 is provided on the left side surface of each middle frame 4 in FIG. Thus, as shown in FIG. 5, after the other end of the spring member 5 is inserted through the opening of the guide portion 11b, the opening of the guide portion 11b is closed by the lid portion 4b of the middle frame 4. 5 can be easily positioned and attached to the cover 11, and the spring member 5 can be prevented from falling off due to its own weight.

  As described above, each of the one end portions of the two spring members 5 is attached to the attachment projections 30c and 31c of the both wing pieces 30 and 31 of the door body 3, and each other end portion is attached to the cover 11 to thereby obtain a spring member. 5 are respectively arranged on both sides of the intermediate part 32 of both blade pieces 30 and 31 and urge the door body 3 so as to move to a position where the plug blade insertion holes 20 and 21 of the voltage electrode are closed.

  On the upper surface and the lower surface of the intermediate portion 32, protrusions 32a projecting upward and downward respectively are integrally formed. As shown in FIG. 6, these upper and lower protrusions 32 a are respectively provided with a guide groove 11 a provided on the upper surface inside the cover 11 along the front-rear direction and a guide groove provided on the upper surface of the middle frame 4 along the front-rear direction. 4a is slidably disposed. Thus, the door body 3 is slidable in the front-rear direction while being sandwiched between the cover 11 and the middle frame 4. In addition, both wing pieces 30 and 31 are swingable in the vertical direction around each protrusion 32a.

  The end opposite to the side connected to the intermediate part 32 of the wing pieces 30, 31 is in contact with a stopper 11 c provided integrally with the inner wall of the cover 11 when the door body 3 swings and tilts. It is supposed to be. For this reason, if it is going to move the door body 3 to the front-back direction in the state where the door body 3 rock | fluctuated and inclined, the movement of the door body 3 will be prevented because the said edge part contacts the stopper 11c. That is, the stopper 11c serves as a blocking means for blocking the movement of the door body 3 in the front-rear direction.

  Hereinafter, specific examples of the blocking means will be given. As shown in FIG. 7 (a), when the door body 3 does not swing and is not inclined, the plug blade insertion holes 20 and 21 for one of the voltage electrodes (in the figure, the plug blade of the left voltage electrode). When an object is inserted into the insertion hole 20), the blade piece 30 of the door 3 is pressed and swings downward, and the other blade piece 31 swings upward to plug the right voltage electrode plug blade. It approaches the insertion hole 21 (see FIG. 7B). At this time, as shown in FIG. 8, the end of the wing piece 30 moves to a position facing the stopper 11c of the cover 11 (see the left door 3 in the same figure). Thus, even if the door 3 is opened in this state, the end of the wing piece 30 comes into contact with the stopper 11c and is prevented from moving in the front-rear direction, so that the door 3 is not opened. . Therefore, it is possible to prevent an electric shock by preventing the charging part such as the blade receiving part 6 inside the housing 1 from being touched from the outside.

  Here, in this embodiment, since the spring members 5 are respectively provided on both sides of the intermediate portion 32 of the both wing pieces 30 and 31 of the door body 3, the door body 3 swings and tilts as described above. In this case, each spring member 5 is twisted. For this reason, if the force which presses the door body 3 is lost, the spring member 5 can return to the original state where the wing pieces 30 and 31 are not inclined by the elastic force to return from twisting. Therefore, even if an object is inserted only into the plug blade insertion holes 20 and 21 of either one of the voltage electrodes, the door body 3 can be restored to the original state, so that the three-pole plug is in a state where the door body 3 is inclined. Therefore, it is possible to prevent the door body 3 from being deformed and damaged by forcibly inserting the plug blade of the three-pole plug without inserting the plug blade. In addition, since the spring member 5 is not disposed in the intermediate portion 32 of the door body 3, it is not necessary to form the intermediate portion 32 of the door body 3 thinly, and ensuring sufficient strength by forming it thickly. Can do.

  By the way, in this embodiment, the hooking recessed parts 30b and 31b dented downward are formed in the inclined surfaces 30a and 31a, respectively, and the level | step difference is formed in the inclined surfaces 30a and 31a by the hooking recessed parts 30b and 31b. For this reason, as shown in FIG. 10, when the voltage detection driver A is inserted into the plug blade insertion holes 20, 21 in order to check the conductivity of the blade receiving portion 6, the voltage detection driver is used. The door body 3 can be easily opened by hooking the front end of A to the catching recesses 30b and 31b and pressing in the sliding direction. At this time, since the door body 3 is not pressed in the insertion direction of the plug blade by the distal end portion of the voltage detection driver A, the door body 3 does not swing. Therefore, when the door body 3 is tilted, the blocking means does not work and the door body 3 is not locked, and deformation and breakage of the door body 3 due to an action such as forcibly inserting the voltage detection driver A can be prevented. .

  Note that the shape of the catching recesses 30b and 31b is not limited to the above-described shape, and is, for example, a substantially rectangular recess provided near the center of each of the inclined surfaces 30a and 31a as shown in FIG. It doesn't matter. In short, it is only necessary that a step that can hook the tip of the voltage detection driver A is formed on each of the inclined surfaces 30a and 31a.

  Further, in the present embodiment, as shown in FIGS. 9A and 9B, tapers 30e, 31e, and 11d are respectively provided at portions where the end portions of both blade pieces 30 and 31 and the stopper 11c come into contact with each other. Yes. By appropriately adjusting the inclination angle (angle formed with the other contact surface of the door body 3 or the stopper 11c) α of the tapers 30e, 31e, and 11d, the end portions of the blade pieces 30 and 31 can be adjusted. The contact force at the time of contact with the stopper 11c can be adjusted. Therefore, when an object is inserted only into the plug blade insertion holes 20 and 21 of one of the voltage electrodes with a relatively strong force such as a child's mischief, the stopper 11c functions as a blocking means for simple voltage detection. When the voltage detection driver A is inserted into the door 3 and the door 3 is opened, the stopper 11c can be prevented from functioning as a blocking means.

  If the inclination angle α is set to approximately 30 degrees, the contact force necessary to make the stopper 11c satisfying the standard stipulated in the safety law work as a blocking means, and the door body 3 at the time of a simple electric detection. It is desirable that the contact force at which the stopper 11c does not act as a blocking means when opening can be optimally balanced.

  Further, as shown in FIGS. 12 (a) and 12 (b), a locking projection 11 e having a substantially triangular cross section protruding toward the middle frame 4 is provided on the inner side surface of the cover 11, and on the outer side surface of the middle frame 4. You may provide the to-be-latched part 4e which protrudes toward the cover 11, and the cross-sectional substantially rectangular shape which the latching protrusion 11e latches. In this case, the locking projection 11e is locked to the locked portion 4e by pushing the middle frame 4 into the cover 11 so that the locked portion 4e gets over the locking projection 11e of the cover 11, and the middle frame 4 Is fixed to the cover 11. Thus, the cover 11 and the middle frame 4 can be handled integrally while preventing the door 3 and the spring member 5 housed between the cover 11 and the middle frame 4 from falling off. A work in which a block having the middle frame 4 fixed to the cover 11 with the door 3 and the spring member 5 sandwiched between the middle frame 4 and the body 10 can be incorporated into the body 10 to improve workability during assembly. Can be made.

  The shape of the locking protrusion 11e is not limited to the above-described substantially triangular shape, and may be a substantially rectangular shape as shown in FIG. The point is that the shape can be locked to the locked portion 4e. Further, in the locking projection 11e and the locked portion 4e, it is desirable that the portions that contact each other when the middle frame 4 is pushed into the inside of the cover 11 are formed so as to be inclined so as to guide each other. With this configuration, the middle frame 4 can be easily pushed into the inside of the cover 11.
