Description

  The present invention relates to a plug removal tool that is inserted between a plug and an outlet when the plug is attached to an outlet and performs electrical connection, and is used when the plug is removed from the outlet.

  Conventionally, plugs that are attached to electrical outlets for electrical connection require great force when removed from the outlet. This is because, in order to ensure electrical connection, the pin inserted from the plug is elastically strongly pinched by the blade receiver in the outlet, so that a large force is required to pull out the pin from the blade receiver. . Electrical devices that are supplied with power from a plug may consume power even when not operating, and in recent years, from the viewpoint of power saving, it is recommended that they be disconnected from the outlet when not in use.

  However, since a large force is required to remove the plug, it is difficult for a powerless elderly person to remove the plug. Even if it is not powerless, if there is not enough space around the plug, it is difficult to reliably hold the case of the plug and it is difficult to remove the plug. Furthermore, since resistance quickly disappears after removing, the removed hand gains momentum and cannot be stopped immediately, and there is a risk of hitting the surroundings.

  In order to make it possible to easily remove a plug that is tightly inserted into an outlet, an insertion plug removing jig has been proposed (for example, see Patent Document 1). This insertion plug removing jig is provided with a rotation support bearing on the side surface of the plug. An angle structure part な る serving as a lever is attached to the rotation support bearing through the rotation support shaft. If the plug is inserted into the outlet with the angle structure part 装着 attached to the plug, the plug can be easily removed by the action of the lever by the angle structure part 杆.

  This insertion plug removal jig has a restriction that at least a plug provided with a rotation support bearing on the side surface must be used. There has also been proposed a plug remover that is used by being sandwiched between a plug case and an outlet when a general plug and an outlet are installed without a rotation support bearing or the like (see, for example, Patent Document 2). In this plug remover, the extraction part is sandwiched between the plug and the surface of the outlet. A pull-out ring is integrally connected to the end of the pull-out portion, and the pull-out ring is pulled when pulling out the plug from the outlet. In order to facilitate the drawing, it has also been proposed to attach scissors members on both sides of the extraction part.

  When a general plug and an outlet are attached, when the plug is used by being sandwiched between the case and the outlet, a simple plug extraction (see Patent Document 3) that uses an insulator to facilitate plug extraction, or an outlet A release plate (see Patent Document 4) has also been proposed. In these cases, when the plug and the outlet are mounted, plate-like portions that protrude from the portion sandwiched between the plug and the outlet to both sides in the width direction where the pins are arranged act as insulators. When the plug is pulled out of the outlet, the plate-shaped part is sandwiched from both sides, so that the plug can be pulled out without applying a large force away from the surface of the outlet.

Japanese Patent Laid-Open No. 10-144394 JP 2000-48907 A JP 2003-234147 A JP 2005-56808 A

  As in Patent Document 2, if the plug is pulled out of the outlet by pulling on the extraction ring, it will not change even if it becomes easy to apply a large force. There is still a risk of hitting your hands. The insulator proposed in Patent Document 2 and disclosed in Patent Document 3 and Patent Document 4 is plate-shaped and needs to be swung so as not to bend in the thickness direction. For this reason, if plate thickness is required and it pinches | interposes between an outlet socket and a plug, there exists a possibility that the reliability of an electrical connection may fall. In JIS C8282-1, 13.5 of the first general requirement stipulates that the gap between the plug and the outlet does not exceed 1 mm when mounted. The angle structure portion 杆 as in Patent Document 1 has an insertion space in which the periphery of the blade of the insertion plug is largely removed on the bottom surface portion, and when an intermediate bar is provided at the tip of the bottom surface portion, a concave groove is formed on the plug side. So that the distance between the plug and the outlet does not increase. This is possible because a dedicated plug is used.

  In general, a power cord with a plug at the tip is attached to an electric product or an electric device that uses commercial AC as a power source. It is difficult to replace such a plug with one having a jig as in Patent Document 1. Moreover, even if the replacement is possible, the attached plug is not used and is wasted.

  Various manufacturers' products are used for electrical appliance plugs and outlets, and the combinations of plugs and outlets are diverse and complicated. However, a unified standard is set for electrical connection so that it can be performed safely and reliably. In particular, a certain standard is set between the pin of the plug and the blade receiver inside the outlet of the outlet.

In today's electrified society, quality control is thorough so that strict common items are kept between the plug and the outlet, but various types of plugs are used, especially plugs. The following issues exist when removing from the outlet.
(1) Prevention of damage to the plug cord: When a force is applied to the cord, the internal conductor is prevented from being easily broken.
(2) Prevention of damage to the insertion slot: Prevents the surface of the outlet from being easily damaged by external force when removing it.
(3) Prevention of non-conformity in the combination of plug and outlet: The combination of the plug pin and the blade holder of the outlet makes it difficult to disconnect once and prevents it from being removed unless a large force is applied. To do.
(4) Preventing accidents when plugs are attached / detached: Reliable assistance for aging and safety of electrified life. With a little force, two fingers can pull through the plug, so that both elderly and children can rest assured.
(5) Prevention of adhesion of dust and debris to the outlet of the outlet: It should be effective even if it is used for a plug of equipment that is used regularly, with a low frequency of attachment / detachment.

  An object of the present invention is to provide a plug removal tool that can reliably remove a plug from an outlet even when a gap between the plug and the outlet is narrow when the plug is attached.

The present invention is a plug remover that is inserted between the plug and the outlet when the plug is attached to the outlet for electrical connection, and is used when the plug is removed from the outlet.
Including two insulators and a bend,
Each insulator is
A bottom plate sandwiched between the plug and the outlet when the plug and the outlet are mounted;

The two insulators are provided on both sides in the width direction where the pins to be inserted from the plug into the outlet are arranged when the plug and the outlet are attached,
The bent part is provided between the pins inserted into the outlet from the plug when the plug and the outlet are attached, and connects between the tips of the bottom plate parts of the two insulator parts ,
In the bottom plate portion of the lever portion, a pin insertion hole is provided so as to follow the change in the position of the pin relative to the bottom plate portion by swinging the lever portion around the bent portion .
When the outer surface covering part of the two insulator parts sandwiches the two side parts from both sides and causes a swinging displacement around the bent part, the part covering the outer surface between the both sides of the plug overlaps.
This is a plug remover characterized by that.

In the present invention, the bottom plate portion of each insulator portion is
An insertion hole having a shape corresponding to the cross-sectional shape of the pin;
Respect insertion hole, in the width direction, is formed in the direction away from the bent portion, and the piece portion curving is provided is pressed by the relative movement with respect to the bottom plate portion of the pin according to the swinging of the lever portion,
It is characterized by that.

  According to the present invention, the insulator portion includes the bottom plate portion, the side portion, and the outer surface covering portion, and is formed in a three-dimensional shape that surrounds at least a part of the plug. Even if the plate thickness is not increased, if an external force is applied to the side portion, the plug can be pulled out from the outlet at the bottom portion.

Further , the plug can be pulled out from the outlet by sandwiching the side portions from both sides in the width direction.

Further , the pin inserted through the bottom surface portion does not prevent the bottom surface portion from swinging, and can act as a lever by swinging around the bent portion.

  Further, according to the present invention, even when the position of the pin relative to the bottom plate portion is changed by the swing around the bent portion, the section portion is pushed and curved, so that the bottom portion can be smoothly swung. be able to.

FIG. 1 is a front view schematically showing a use state of a plug removing tool 1 as an embodiment of the present invention. 2 is a front view, a plan view, and a right side view showing the configuration of the plug removing tool 1 of FIG. FIG. 3 is a front view showing an operation state of the lever portions 2 and 3 in the plug removing tool 1 of FIG. FIG. 4 is a front view showing the configuration of the plug removal tool 21 as Embodiment 2 of the present invention.

  Hereinafter, FIG. 1 shows a use state of the plug removing tool 1 as Embodiment 1 of the present invention, and FIG. 2 shows the configuration thereof. In FIG. 3, the action | operation state of the insulator parts 2 and 3 in the plug removal tool 1 is shown. In FIG. 4, the structure of the plug removal tool 21 as Example 2 of this invention is shown.

  For convenience of explanation, portions that are not described in the drawings to be described may be referred to with reference numerals described in other drawings.

  FIG. 1 shows a schematic configuration of a tip portion of a plug removing tool 1 as an embodiment of the present invention. The plug removal tool 1 includes a lever portion 2.3 and a bent portion 4. The insulator portions 2 and 3 are formed by removing the bottom plate portions 2a and 3a sandwiched between the plug 5 and the case surface 11 of the outlet 10 and at least a part of the side of the plug 5 when the plug 5 and the outlet 10 are attached. An outer surface covering portion 2c that connects between the surrounding side portions 2b and 3b, the bottom plate portions 2a and 3a, and the side portions 2b and 3b and covers at least a part of the outer surface between both sides of the plug 5. , 3c. The bent portion 4 is provided at the tip of the bottom plate portions 2a and 3a of the insulator portions 2 and 3.

  As shown in FIG. 1A, the plug remover 1 is inserted between the plug 5 and the outlet 10 when the plug 5 is attached to the outlet 10 for electrical connection. As shown in b), it is used when the plug 5 is removed from the outlet 10. The plug 5 has pins 7 and 8 to be plugged into the outlet 10 at the lower portion of the case 6 in the figure. The pins 7 and 8 are arranged at intervals in the width direction. Although the case 6 incorporates electrical connection portions to the pins 7 and 8 and mechanical holding means for the flexible cable 9 upward in the figure, the illustration is omitted. Inside the outlet 10, there are provided blade receivers 12 and 13 which receive the inserted pins 7 and 8 and elastically sandwich them, and further have an electrical connection to the blade receivers 12 and 13 and mechanical holding means. Although it is incorporated, illustration is omitted.

  When the plug 5 is removed from the outlet 10, the side portions 2b and 3b of the lever portions 2 and 3 shown in FIG. In FIG. 1A, the pins 7 and 8 are fitted to the blade receivers 12 and 13. When the side portions 2b and 3b of the insulator portions 2 and 3 are sandwiched from both sides, as shown in FIG. 1B, the bent portion 4 at the tip of the bottom plate portions 2a and 3a becomes a fulcrum and swings around the bent portion 4 By the displacements 4a and 4b, the insulator portions 2 and 3 are lifted from the case surface 11 of the outlet 10 in the clockwise direction and the counterclockwise direction. At this time, the pins 7 and 8 can be pulled out from the fitted state with the blade supports 12 and 13. If the pins 7 and 8 are out of the fitted state with the blade receivers 12 and 13, the resistance to pull out the plug 5 becomes small and can be easily removed. Even if the side portions 2b and 3b are sandwiched between two fingers, the pins 7 and 8 can be sufficiently removed from the blade supports 12 and 13 by the action of the lever, and the case 6 and the flexible cable 9 can be touched. In addition, the elderly person and the child can remove the plug 5 with peace of mind.

  2A and 2B show the configuration of the plug removing tool 1 of FIG. 1, in which FIG. 2A is a plan view, FIG. 2B is a front view, and FIG. 2C is a right side view. The plug removal tool 1 can be integrally manufactured by blow molding or the like using an electrically insulating plastic having a thickness of 1 mm or less as a material. Further, the bottom plate portions 2a and 3a, the side portions 2b and 3b, and the outer surface covering portions 2c and 3c can be formed by bending from a flat developed shape. Furthermore, it can be formed by using the bottom of an existing cosmetic liquid container or the like.

  As shown in FIG. 2A, the bottom plate portions 2a and 3a of the plug removing tool 1 are provided with pin insertion holes 7a and 8a through which the pins 7 and 8 are inserted. The pin insertion holes 7a and 8a are, for example, pins 7 and 8 so as to be able to follow changes in the positions of the pins 7 and 8 with respect to the bottom plate portions 2a and 3a by the swinging of the lever portions 2 and 3 around the bent portion 4. It may be formed so that there is room in the width direction, which is the arrangement direction. In the present embodiment, the insertion holes 7a and 8a having a shape corresponding to the cross-sectional shape of the pins 7 and 8 and the portions of the bottom plate portions 2a and 3a on the side away from the bent portion 4 in the width direction with respect to the insertion holes 7a and 8a. Section portions 7b and 8b are provided, which can be pushed by relative movement of the positions of the pins 7 and 8 by swinging the lever portions 2 and 3. The section portions 7b and 8b can be formed by inserting cuts 7c and 7d; 8c and 8c extending in the width direction on both sides.

As shown in FIG. 2 (c), the lever unit 3 is as wide in the bottom plate 3 a. The same applies to the insulator 2. This is so that the plug 5 having a wide mounting surface to the outlet 10 can be used. Such a plug 5 does not need to be wide when excluded from the target.

In addition, in FIG. 2, the example which has provided the seal frames 15 and 16 in the baseplate parts 2a and 3a of the plug removal tool 1, respectively is shown. The seal frames 15 and 16 are made of a resilient material such as silicon rubber and surround the peripheries of the insertion holes 7a and 8a. Even if irregularities or gaps occur between the bottom plate portions 2a and 3a of the plug removing tool 1 and the surface 11 of the outlet 10 into which the plug 5 is inserted, if the seal frames 15 and 16 are provided, the electrical insulation is lowered. It is possible to prevent dust and the like from entering the periphery of the pins 7 and 8.

  FIG. 3 shows an operation state of the lever portions 2 and 3 in the plug removing tool 1 of FIG. In the state shown in FIG. 1B, the pins 7 and 8 inserted up to Qa in FIG. 1A are pulled out to Qb by ΔQ. If the inclination angle of the bottom plate portion 2a is θ, ΔQ is a value obtained by multiplying the distance between the bent portion 4 and the corner portion of the case 6 of the plug 5 by sin θ. With the inclination of the angle θ, the position of the pin 7 with respect to the bottom plate portion 2a is a value obtained by dividing the distance from the bent portion 4 to the pin 7 on the surface 11 of the outlet by cos θ. The section 7b shown in FIG. 2A is curved with a relative change in the position of the pin 7.

  Since the insulator part covers the periphery of the pins 7 and 8 when the plug is attached to the outlet, even if the plug remover 1 is used for the plug 5 of equipment that is used frequently and is not frequently attached, There is an effect to prevent adhesion.

  FIG. 4 shows a configuration of a plug removal tool 21 as Embodiment 2 of the present invention. The plug removal tool 21 of the present embodiment is similar to the plug removal section 1 of the first embodiment, and the corresponding parts are indicated by 20 different reference numerals, and redundant description is omitted.

  In the present embodiment, the coupling portions 22d and 23d are provided at the distal ends of the side portions 22b and 23b of the lever portions 22 and 23, and the coupling portions 25a and 26a provided at the lower ends of the pressing members 25 and 26 are detachable. When the pressing members 25 and 26 are attached, the clamps 25 b and 26 b provided at the upper ends of the pressing members 25 and 26 can be pressed by holding the flexible cable 9, and the plug removing tool 21 can be prevented from being detached from the plug 5. Also, the bottom plate portions 22a and 23a can be provided with seal frames 15 and 16 as shown in FIG. In order to prevent detachment from the plug 5, it may be hung not by the pressing members 25 and 26 but by a string.

  Power saving is a high concern in the society and living environment surrounding energy. Unplugging unnecessary plugs from electrical outlets greatly contributes to lower power consumption. As the frequency of unplugging from the outlet increases, more trouble is predicted from the burden. The utility value of the plug removers 1 and 21 of the present invention corresponds to the prediction.

  The plug removers 1 and 21 can be manufactured and sold as independent products, as well as novelty products. It can be distributed as an announcement medium for various service industries, medicines, and devices in the aging society. Moreover, since it can also process and form from the bottom part of an existing container, if there is an adult's appropriate instruction | indication, what can help an elderly person with a child's work can also be produced easily.
