Description

  The present invention relates to an outlet.

  Patent Document 1 discloses an outlet for a plug having a flat plug blade. This outlet is an embedded outlet that is used by being embedded in the wall surface with the front surface of the case exposed, and has a plug blade insertion port on the front surface for inserting a flat plug blade of the plug. And a plurality of blade receiving springs received in the case and receiving the flat plug blade inserted into the plug blade insertion port and electrically connected to an electric wire extending from the outside.

  For example, as shown in FIG. 17, a conventional blade receiving spring includes a pair of spring pieces 120 facing each other at a predetermined interval in order to sandwich a flat plug blade of a plug inserted from a plug blade insertion port, The frame 130 is formed at a rear end (lower end in FIG. 17) of the pair of spring pieces 120. That is, the conventional blade receiving spring 110 is arranged in the case in the order of the pair of spring pieces 120 and the frame 130 from the side closer to the plug blade insertion port.

Japanese Patent Laid-Open No. 10-326658

  FIG. 18 shows a state where the tip of the flat plug blade 210 of the plug 200 is inserted into the outlet 100 having the blade receiving spring 110 shown in FIG. As shown in FIG. 18, the conventional outlet has a distance L100 between the front surface 101 of the case and the housing of the plug when the tip of the flat plug blade 210 contacts the front end of the blade receiving spring 110 (the upper end of FIG. 18). However, there is a risk that the person's fingertip touches the flat plug blade 210 to cause an electric shock.

  In order to prevent such an inadvertent electric shock, for example, as shown in FIG. 19, the position of the blade receiving spring 110 is lowered to the rear (downward in FIG. 19), and the flat plug blade 210 and the blade receiving spring 110 contact each other. A method of moving the position backward is conceivable. However, in this case, if the size of the case is the same, it is necessary to shorten the length of the frame 130 and the pair of spring pieces 120 as much as the blade receiving spring 110 is lowered. The spring force becomes small, and it becomes difficult to secure the insertion / extraction force and contact pressure.

  In addition, the spring piece 120 is provided with a bottom (not shown) that engages with a bottom hole provided in the flat plug blade 210. The distance from the front of the case to the center of the bottom is determined by the Electrical Appliance and Material Safety Law, It is defined in the JIS standard (JIS C 8303) and the like. Accordingly, when the position of the blade receiving spring 110 is simply lowered backward, there is a problem that the position of the bocce falls below a specified value.

  Further, since the conventional blade receiving spring 110 needs to be provided with the guiding piece 121 at the front end of each spring piece in order to guide the flat plug blade 210 between the pair of spring pieces 120 as described above, There is also a problem that the overall length (height) of the receiving spring is increased, and as a result, the thickness (height) of the case is increased.

  The present invention has been made in view of the above problems, and its object is to prevent inadvertent electric shock while ensuring the same insertion / extraction force and contact pressure as those of conventional blade receiving springs. It is another object of the present invention to provide an outlet capable of reducing the thickness of the case.

  The outlet of the present invention includes a case having a plug blade insertion port for inserting a flat plug blade of a plug on the front surface, and the flat plug blade housed in the case and inserted into the plug blade insertion port. An outlet for a plug having a flat plug blade provided with a plurality of blade receiving springs that are electrically connected to an electric wire extending from the outside and receiving each of the blade receiving springs to hold the flat plug blade A pair of spring pieces facing each other at a predetermined distance and a frame holding the pair of spring pieces, the frame facing a pair of sides facing each other at a wider interval than the distance between the pair of spring pieces A pair of springs, a connecting piece for connecting the pair of side pieces laterally, and a connecting piece extending from a rear end of each side piece opposite to the plug blade insertion port. A piece extends from the rear end of each connecting piece opposite to the plug blade insertion port. And wherein the Rukoto. That is, the blade receiving spring of the present invention is arranged in the case in the order of the frame and the pair of spring pieces from the side closer to the plug blade insertion slot, and the side piece of the frame is from the plug blade insertion slot. It is formed wider than between the pair of spring pieces so that the inserted flat plug blade does not contact the side pieces. Therefore, the contact position between the flat plug blade and the blade receiving spring is far from the plug blade insertion port, and when the tip of the flat plug blade and the spring piece are in contact, the distance between the front of the case and the plug housing is small. This prevents a person's fingertip from entering and prevents an inadvertent electric shock. In addition, the contact position of the flat plug blade and blade receiving spring can be moved away from the plug blade insertion port without shortening the length of the frame or spring piece, so that the insertion force and contact force equivalent to those of conventional blade receiving springs can be obtained. Pressure can be secured. Furthermore, the blade receiving spring of the present invention can guide the flat plug blade inserted from the plug blade insertion port between the pair of spring pieces by the frame and the connecting piece, so that the leading piece is inserted into the front end of the pair of spring pieces. The height of the blade receiving spring can be reduced as compared with the conventional blade receiving spring provided with, and as a result, the thickness (height) of the case can be reduced.

  Preferably, the connecting piece extends obliquely in a direction approaching the pair of spring pieces from a rear end of each side piece opposite to the plug blade insertion opening. In this case, the flat plug blade inserted from the plug blade insertion port can be easily guided between the pair of spring pieces by the connecting piece.

  Preferably, the outlet includes a terminal member that is electrically connected to an electric wire inserted into the case from the outside of the case, and the frame includes a connecting piece between one side edge of the pair of side pieces. The front end of one side piece of the frame and the terminal member are connected by a lead piece, the front end of the other side piece is a free end, and the terminal member and the lead piece The blade receiving spring is formed by bending a single metal plate. In this case, the blade receiving spring and the terminal member can be efficiently formed from a single metal plate, and the blade receiving spring and the terminal member can be easily assembled.

  In the above case, preferably, the spring piece extending from the one side piece of the frame has a slit along the insertion direction of the plug. By forming the slit along the insertion direction of the plug in the spring piece, a spring piece having a twin contact can be formed, and the contact between the spring piece and the flat plug blade can be improved. Further, if a slit is formed in the spring piece extending from the side piece of the frame whose front end is a free end, it becomes difficult to ensure a predetermined holding force of the spring piece, but the one of the one connected to the terminal member By forming a slit in the spring piece extending from the side piece, a twin contact can be configured without reducing the holding force.

  The shapes of the blade receiving spring and the terminal member are not limited to the above-mentioned shapes. For example, the frame has a substantially U shape in which one side edge of the pair of side pieces is connected by the connecting piece. The connecting piece and the terminal member are connected by a lead piece, the front ends of both side pieces of the frame are free ends, and the terminal member, the lead piece, and the blade receiving spring are a single metal plate. It is also preferable to be formed by bending.

  Preferably, the pair of spring pieces are arranged non-parallel so that an interval between the pair of spring pieces becomes narrower from the connecting piece side of the frame toward the distal end side of the side piece. When the flat plug blade is inserted between the pair of spring pieces, the spring pieces are more likely to spread on the tip side of the side pieces than on the connecting piece side. Therefore, when the flat plug blade is inserted between a pair of spring pieces, the gap between the spring pieces on the front end side of the side piece that tends to spread is made smaller than the gap between the spring pieces on the connecting piece side. The blade and the pair of spring pieces can be in good contact.

  Preferably, the case includes a box-shaped body whose front surface is open, and a cover that has the plug blade insertion opening on the front surface and covers the front surface of the body, and each of the blade receiving springs includes the frame. The pair of spring pieces are inserted into the body in a state of protruding from the front surface of the body, and the body has a rib protruding toward the connecting piece of the frame, and the connecting piece of the frame Is supported on the rib. Alternatively, the case includes a box-shaped body having an open front surface and a cover that has the plug blade insertion opening on the front surface and covers the front surface of the body, and each of the blade receiving springs includes the frame that The pair of spring pieces are inserted into the body in a state of protruding to the front surface of the body, the connecting piece has a rib protruding toward the body, and a tip of the rib is located on the front surface of the body. Contact is also preferred. In these cases, the force applied to the blade receiving spring when the flat plug blade is inserted can be received by the rib, and deformation of the blade receiving spring can be suppressed.

  As described above, the outlet of the present invention can prevent inadvertent electric shock while ensuring the same insertion / extraction force and contact pressure as those of conventional blade receiving springs, and can further reduce the thickness of the case. it can.

  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

  The outlet according to the present embodiment is an embedded outlet that is used by being embedded in a wall surface with the front surface of the case exposed. As shown in FIG. 1, this outlet includes a case 1 having two sets of plug blade insertion ports 12 for inserting a flat plug blade 210 of a plug 200 on the front surface, and is housed in the case 1. A plurality of blade receiving springs 2 that receive the flat plug blades 210 inserted into the mouth 11 and are electrically connected to electric wires (not shown) extending from the outside are provided.

  As shown in FIG. 2, the case 1 has a box-shaped body 10 made of a synthetic resin whose front surface (upper surface in FIG. 2) is open and a plug blade insertion port 12 on the front surface and covers the front surface of the body 10. And a cover 11 made of synthetic resin. The body 10 and the cover 11 are coupled to each other by an assembly frame 50 that also serves as an attachment frame for attachment to the construction surface.

  The plug blade insertion port 12 has a shape corresponding to the plug 200 for a rated voltage of 125 V and a rated current of 15 A defined in JIS C 8303, and has a rectangular shape so that the flat plug blade 210 of the plug 200 can be inserted. is doing.

  Each blade receiving spring 2 is provided corresponding to each plug blade insertion opening 12 and is formed integrally with a terminal member 3 electrically connected to an electric wire inserted into the case. The blade receiving spring 2 will be described in detail later.

  The terminal member 3, together with the chain spring 4 and the release button 6, constitutes a quick connection terminal that chains an electric wire inserted into the case 1 from a hole (not shown) provided on the rear surface of the body 10. That is, as shown in FIG. 3, the terminal member 3 has a pressing piece 30 extending rearward (downward in FIG. 3) so as to face the chain spring 4 and inserted into the case 1. The electric wire is held between the chain spring 4 and the pressing piece 30 and is electrically connected to the terminal member 3. The electric wire held between the chain spring 4 and the holding piece 30 is prevented from being pulled out by the tip of the chain spring 4 biting into the electric wire. When the electric wire is pulled out, the chain spring 4 is elastically deformed by pulling up the release button 6 urged rearward by the leaf spring 5, and the electric wire can be pulled out.

  Further, the cover 11 includes a grounding plug blade insertion port 13 into which a plug blade of a grounding electrode of a plug with a grounding electrode can be inserted. In the case 1, the grounding inserted from the grounding plug blade insertion port 13 is provided. A grounding electrode blade receiving spring 7 for receiving the plug blade of the grounding electrode of the electrode plug is disposed.

  Hereinafter, the blade receiving spring 2 will be described in detail. As shown in FIG. 3, each blade receiving spring 2 includes a pair of spring pieces 21 facing each other at a predetermined interval in order to hold the flat plug blade 210 and a frame 22 holding the pair of spring pieces. Become. The frame 22 includes a pair of side pieces 23 facing each other at a wider interval than the interval between the pair of spring pieces, and one of the pair of side pieces 23 so that the flat plug blades inserted from the plug blade insertion ports do not come into contact with each other. And a connecting piece 24 for connecting the side edges of each side piece 23 (substantially U shape in plan view), and the rear end of each side piece 23 opposite to the plug blade insertion port (lower end in FIG. 3). A connecting piece 25 (see FIG. 1) is extended. Each connecting piece 25 extends obliquely in a direction approaching each other from the rear end of each side piece 23 toward the rear (downward), and the pair of spring pieces 21 are connected to the plug blade insertion port of each connecting piece 25. It extends (hangs down) from the rear end (lower end) of the opposite side.

  Further, the tip of one side piece 23 of the U-shaped frame 2 and the terminal member 3 are connected by a lead piece 26, and the tip of the other side piece 23 of the frame 2 is a free end (in other words, The other side piece 23 of the frame 2 is a cantilever piece supported by the connecting piece 24).

  As shown in FIGS. 1 and 4, the blade receiving spring 2 configured as described above has a pair of spring pieces 21 formed inside the body 10 with the frame 2 protruding from the front surface of the body 10. Inserted into the storage recess 14. The body 10 has a rib 15 that protrudes toward the connecting piece 24 of the frame, and the connecting piece 24 of the frame is supported on the rib 15. By providing the rib 15, the force applied to the blade receiving spring 2 when the flat plug blade 210 is inserted can be received by the rib 15, and deformation of the blade receiving spring 2 can be suppressed.

  The front surface of the body into which the blade receiving spring 2 is inserted is covered with a cover 11. Thereby, the blade receiving spring 2 is arrange | positioned in the case 1 in order of the flame | frame 2 and a pair of spring piece 21 from the direction close | similar to the plug blade insertion port 12. FIG.

  As shown in FIG. 1, when the flat plug blade 210 of the plug 200 is inserted into the plug blade insertion port 12, the flat plug blade 210 does not contact with the pair of side pieces 23 of the frame 2, and between the pair of side pieces 23. After passing, the pair of spring pieces 21 come into contact. When the flat plug blade 210 and the pair of spring pieces 21 come into contact with each other, the distance L1 between the front surface of the case 1 and the housing of the plug 200 is so short that a human fingertip does not enter. There is no risk of inadvertent electric shock by touching the flat plug blade 210. That is, in the outlet of the present embodiment, the blade receiving spring 2 is arranged in the case 1 in the order of the frame 2 and the pair of spring pieces 21 from the side closer to the plug blade insertion port 12. The contact position between 210 and the blade receiving spring 2 is moved backward (downward). Accordingly, as shown in FIG. 5 in comparison with the conventional outlet, the distance L1 between the front surface of the case 1 and the housing of the plug 200 when the tip of the flat plug blade 210 and the pair of spring pieces 21 contact each other is This is shorter than the conventional distance L100. Therefore, there is no fear that a human fingertip touches the flat plug blade 210 and carelessly receives an electric shock.

  Furthermore, since the length of the frame 2 and the spring piece 21 is the same as that of the conventional blade receiving spring, it is possible to ensure the same insertion / extraction force and contact pressure as those of the conventional blade receiving spring.

  The distance L2 shown in FIG. 5 indicates the distance from the front surface of the case to the center of the bocce (11.7 ± 1 mm in the JIS standard). The outlet of this embodiment is the same as the conventional outlet. The distance L2 from the front surface of the case to the center of the bocce satisfies the specified value.

  Further, in the blade receiving spring 2 of the present embodiment, the flat plug blade inserted from the plug blade insertion port is easily guided between the pair of spring pieces 23 by the connecting piece 25 after entering the frame 2. . That is, the blade receiving spring 2 according to the present embodiment serves as a conventional guiding piece for guiding the flat plug blade between the pair of spring pieces by the frame 2, particularly the connecting piece 25, and the conventional blade shown in FIG. Unlike the receiving spring 110, it is not necessary to provide the guiding piece 121 at the front end of the pair of spring pieces 120. Therefore, as shown in FIG. 6, the height H2 of the blade receiving spring 2 of the present embodiment can be made lower by the amount of the conventional guiding piece 121 than the height H110 of the conventional blade receiving spring. As a result, as shown in FIG. 5, the thickness (height) H1 of the case 1 of the present embodiment can be made smaller than the thickness (height) H100 of the conventional case 100.

  As shown in FIG. 7, a slit 27 is formed in the spring piece 21 extending from one side piece 23 of the frame 2 connected to the terminal member 3 via the lead piece 26 along the plug insertion direction. ing. The slit 27 extends from the rear edge of the side piece 23 to the top of the connecting piece 25. By forming the slit 27 in the spring piece 23, a twin contact (multi-point contact structure) can be formed, and the contact between the spring piece 21 and the flat plug blade 210 can be improved. Here, in this embodiment, it should be noted that the slit 27 is provided in the spring piece 21 extending from the one side piece 23 connected to the terminal member 3. When the slit 27 is provided in the spring piece 21 which is not connected to the terminal member 3 and extends from the other side piece 23 whose front end is a free end, the holding force of the spring piece 21 is reduced. Therefore, by providing a slit 27 in the spring piece 21 extending from the one side piece 23 connected to the terminal member 3 through the lead piece 26, a twin contact is formed without reducing the holding force of the spring piece 21. It can be done.

  Further, as shown in FIG. 8, the pair of spring pieces 21 are arranged non-parallel so that the distance between the pair of spring pieces becomes narrower from the connecting piece 24 side of the frame 2 toward the distal end side of the side piece 23. ing. That is, the distance D1 between the spring pieces on the distal end side of the side piece 23 is smaller than the distance D2 between the spring pieces on the connecting piece 24 side. In the present embodiment, only one side piece 23 of the U-shaped frame 2 is connected to the terminal member 3 by the lead piece 26, and the other side piece 23 is a cantilever piece. Therefore, when the flat plug blade 210 is inserted between the pair of spring pieces 21, the spring piece 21 on the tip side of the side piece 23 (in other words, the tip side of the cantilever piece) is more than the spring piece 21 on the connecting piece side. Easy to spread. Accordingly, when the pair of spring pieces 21 are parallel, as shown in FIG. 9A, when the flat plug blade 210 is inserted between the pair of spring pieces 21, the spring piece 21 on the tip side of the side piece and the flat plug blade 21 There may be a gap between them, contact reliability may be reduced, and abnormal temperature rise may occur. Therefore, by setting the distance D1 between the spring pieces on the distal end side of the side piece 23 which is easy to spread to be smaller than the distance D2 between the spring pieces on the connecting piece side, as shown in FIG. When inserted between the spring pieces, the flat plug blade 210 and the pair of spring pieces 21 are in good contact with each other, and the contact reliability can be improved.

  The blade receiving spring 2, the lead piece 26, and the terminal member 3 of this embodiment are formed by bending a single metal plate shown in FIG. Thus, if the structure which forms the blade receiving spring 2, the lead piece 26, and the terminal member 3 integrally from one metal plate is employ | adopted, the blade receiving spring 2, the lead piece, and the terminal member will be formed from another member. Compared to the case, the number of parts can be reduced and the cost can be reduced. Also, assembly work is simplified. In addition, in the development view of the metal plate shown in FIG. 10, by providing a notch in the spring piece 21 to the extent that the holding force of the spring piece 21 is not affected as in the portion shown by the region X in FIG. The mold can be largely removed, the punch strength is increased, and the life of the mold can be extended.

  In addition, the shape of the blade receiving spring 2, the lead piece 26, and the terminal member 3 is not limited to the above-mentioned shape, For example, a shape as shown in FIG. 11 may be sufficient. The blade receiving spring 2 shown in FIG. 11 has a substantially U shape in which one side edge of a pair of side pieces 23 is connected by a connecting piece 24, and the connecting piece 24 and the terminal member 3 are connected by a lead piece 26. The front ends of both side pieces 23 of the frame 2 are free ends and are bent inward. Also in this case, the blade receiving spring 2, the lead piece 26, and the terminal member 3 can be integrally formed by bending a single metal plate shown in FIG. In the development view shown in FIG. 12, the loss of one metal plate can be greatly reduced as compared with the development view shown in FIG.

  In the present embodiment, the terminal member 3 and the chain spring 4 are separate parts. However, for example, as shown in FIG. 13, the terminal member 3 and the chain spring 4 may be integrally formed.

  Further, in the present embodiment, the rib 15 is provided on the front surface of the body 10 and the connecting piece 24 is supported on the rib 15 in order to receive the force applied to the blade receiving spring 2 when the flat plug blade 210 is inserted. As shown in FIG. 14A, a rib 28 that protrudes toward the front surface of the body may be formed at the rear end of the connecting piece 24 of the frame 2 so that the tip of the rib 28 contacts the front surface of the body 10. Alternatively, as shown in FIG. 14B, a rib 15 may be provided on the front surface of the body 10 and a rib 28 may be provided on the rear end of the connecting piece 24 so that the rib 15 and the rib 28 come into contact with each other. At this time, as shown in FIG. 15A, if the groove 16 is provided in the rib 15 on the body side and the rib 28 on the connecting piece side is inserted into the groove 16, the blade receiving spring 2 in the short direction of the case 1 is formed. Movement can be regulated. Alternatively, as shown in FIG. 15B, a groove 29 may be provided in the rib 28 on the connecting piece side, and the rib 15 on the body side may be inserted into the groove 29.

  Further, in the present embodiment, the slit 27 is provided on one side piece 23 to form a twin contact, but of course, the slit 27 may not be provided. Also in this case, as shown in FIG. 16, the distance D1 between the spring pieces on the distal end side of the U-shaped frame 2 is smaller than the distance D2 between the spring pieces on the connecting piece 24 side of the U-shaped frame. It is preferable to arrange the pair of spring pieces 21 as described above.

  In addition, the outlet of the present embodiment is an embedded outlet, but the outlet of the present invention is not limited to the embedded outlet, and the outlet of the present invention may be an outlet such as a table tap. Applicable.
