<First Embodiment>
<Structure of essential parts of assisting tool>
FIG. 1 is a perspective view showing a main configuration of an auxiliary tool 1A according to the first embodiment of the present invention. FIG. 1 also shows a plug (insertion plug) 8 to which the auxiliary tool 1A is attached and an outlet 9 that can be inserted. In FIG. 1 and subsequent figures, in order to clarify the directional relationship, an XYZ orthogonal coordinate system is attached as necessary, and the (+ Y) direction is upward, the (−Y) direction is downward, The (−X) direction side is defined as the front surface, and the (+ X) direction side is defined as the back surface.

  The auxiliary tool 1A is attachable to and detachable from a plug 8 that supplies power to an electrical product or the like via a flexible wire (cable) 89, and the separating operation of the plug 8 inserted into the insertion port 91 of the outlet 9 is performed. Has a function to assist. Specifically, by inserting two pins 81 protruding as projecting pieces from the bottom surface of the plug body 80 whose lower part is formed in a rectangular parallelepiped shape into the two holes 10h provided in the lower part of the auxiliary tool 1A, The auxiliary tool 1A is integrally attached to the plug 8. Then, when the plug 8 is inserted into the outlet 9, the auxiliary tool 1A is pressed so as to be picked with two fingers of one hand, whereby the outlet 9 and the plug 8 are separated from each other, and the mechanical holding and electrical connection thereof are achieved. Release of the established connected state will be assisted. The configuration of the auxiliary tool 1A will be described in detail with reference to FIGS.

  FIG. 2 is a front view for explaining the configuration of the auxiliary tool 1A. Here, FIG. 2 shows the auxiliary tool 1A attached to the plug 8, and the upper surface 91f of the insertion port 91 when the plug 8 is inserted into the outlet 9 is represented by a virtual line. Moreover, FIG. 3 is the figure which expanded the upper right part of 1 A of auxiliary tools in FIG.

  The auxiliary tool 1A is integrally formed of plastic (synthetic resin) such as polypropylene, for example, and can hold a certain shape (hereinafter also referred to as “basic shape”) shown in FIGS. ing. And 1 A of auxiliary tools are provided with the connection part 10 connected adjacent to the plug main body 80, and a pair of operation part 11 which couple | bonds with the upper end of the connection part 10, and protrudes in the +/- Z direction. The operation unit 11 has a structure for assisting a separating operation for separating the outlet 9 adjacent to the plug 8 relatively downward (a separating operation assisting structure).

  The connecting portion 10 has a substantially U-shaped three-dimensional shape surrounding the plug body 80 from three directions of the (± Z) direction and the (−Y) direction, and a pin (plug terminal) 81 of the plug 8. Is provided with a bottom portion 101 in which two rectangular holes 10h are formed, and a pair of side plates 105 coupled to both ends of the bottom portion 101 in the ± Z direction.

  The bottom portion 101 includes a rectangular (rectangular) bottom plate 102 having a main surface parallel to the XZ plane, and a pair of reinforcing plates 103. The bottom plate 102 has a thickness (for example, a thickness of about 1 mm) that does not affect the mechanical holding and electrical connection when the plug 8 is inserted into the outlet 9. Further, the reinforcing plate 103 is connected to both ends of the bottom plate 102 in the ± X direction and is also connected to the lower end portion of the side plate 105, and the operation unit 11 is pushed toward the plug body 80 with a finger as will be described later. At this time, it plays a role of suppressing deformation (curvature) of the bottom plate 102. The separation distance between the reinforcing plates 103 is set to be equal to or greater than the width Wo of the plug body 80 in the X-axis direction.

  Each of the pair of side plates 105 has a rectangular shape, and is configured as a flat plate-like portion (hereinafter also abbreviated as “flat plate”) extending in the vertical direction (+ Y direction) from both ends of the bottom plate 102. Note that the distance between the side plates 105 is set to be equal to or greater than the width of the plug body 80 in the Z-axis direction. Each side plate 105 has both flat main surfaces.

  The operation unit 11 has a structure that is mirror-symmetric with respect to the plug body 80, and is provided along each side wall 80w of the plug body 80 facing in the Z-axis direction. The side wall 80w is formed as a relatively flat wall surface. In addition, the operation unit 11 includes a band-shaped inner portion 111 that bends in a wave shape (a bowl shape), and a band-shaped outer portion 115 that covers the inner portion 111 from the outside. Here, the width Wp of the operation portion 11 (the inner portion 111 and the outer portion 115) in the X-axis direction is set to be equal to or larger than the width Wo of the side wall 80w and equal to the entire width of the bottom portion 101 in the X-axis direction.

  The inner portion 111 is provided with a bent section Bs (section from the uppermost bent section B1 to the lowermost bent section B3) having three bent sections B1 to B3 along the side wall 80w. More specifically, in the inner portion 111, a wave-shaped bent section Bs having three bent portions B1 to B3 whose bending directions are alternately reversed downward is a flat plate 117 (described later) of the outer portion 115. The plug body 80 is provided between the side wall 80 w of the plug body 80.

  The inner portion 111 includes a rectangular (rectangular) flat plate 112 connected to the bent portions B1 and B2, a rectangular flat plate 113 connected to the bent portions B2 and B3, and a bent upper end. Connected to the part B3, the lower end is provided with a rectangular flat plate 114 disposed in the vicinity of the upper surface 91f (FIG. 2) of the insertion port 91, in other words, in the vicinity of the lower end 80e of the side wall 80w. That is, two flat plates in which both ends in the vertical direction (hereinafter also referred to as “upper and lower ends”) are connected to two adjacent bent portions that are adjacent to each other in the bent direction among the three bent portions B1 to B3. 112 and 113 are provided, and a flat plate 114 having upper and lower ends including a lower end (tip) of the inner portion 111 and a connection end connected to the bent portion B3 closest to the lower end is provided. Here, the distinction between each of the flat plates 112 to 114 and each of the bent portions B1 to B3 is determined based on, for example, the presence or absence of curvature with respect to the center line, the surface, and the like in a front view. In addition, in each bending part B1-B3, it is preferable to make an intermediate part thinner than the thickness of the both ends (upper and lower ends).

  In the inner portion 111, the lengths of the flat plate 112 and the flat plate 113 (length when deployed in the Y-axis direction) are set to be substantially equal, while the flat plate 114 on the tip side is longer than the flat plates 112 and 113. ing. Further, in the flat plate 114, a moving amount (hereinafter referred to as “maximum protruding amount”) in which the tip of the inner portion 111 moves from the lower end surface of the bottom plate 102 (the lower end 105e of the side plate 105) to the protruding limit position in the downward direction. It is set longer than Lf (see FIG. 4). This is because when the operation portion 11 is pressed toward the side wall 80w of the plug body 80 as described later, pressure (compression stress) is generated in the longitudinal direction (Y-axis direction) of the inner portion 111. If the bent portion B3 is positioned near the lower end 105e of the side plate 105 below or above the lower end 105e (the lower end surface of the bottom portion 101), the bent portion B3 bends due to compressive stress and is pushed by the plug 8. It is because raising becomes difficult. Note that the length of the flat plate 114 is preferably 1.5 times or more, more preferably 2 times or more of the length (average value) of each of the other flat plates 112 and 113. In other words, the length of each of the flat plates 112 and 113 is preferably (2/3) times or less, more preferably 0.5 times or less of the length of the flat plate 114. The angle θa formed between the flat plate 112 and the flat plate 113 is set to about 60 °, and the angle θb formed between the flat plate 113 and the flat plate 114 is set to an obtuse angle of 90 ° or more.

  The outer portion 115 has one bent portion B5, and extends from the bent portion B5 downward to the rectangular upper plate 116 connected to the bent portion B5 (and the bent portion B1) and the upper end of the side plate 105. The side plate 105 and the side wall 80w of the plug main body 80 and a rectangular flat plate 117 configured as a straight section Fs substantially parallel to the side plate 105 are provided. Here, the angle θp formed by the upper plate 116 and the side plate 105 is set to about 60 °.

  The upper plate 116 is formed so that its thickness increases in proportion to the distance from the side plate 105 in a front view as shown in FIG. 3, and is bent with the bent portion B1 provided at the upper end portion of the inner portion 111. It is connected to part B5. Here, an angle θc formed by the upper plate 116 and the flat plate 112 of the inner portion 111 is set to about 60 °. The upper plate 116 and the inner portion 111 function as a deforming portion Tr1 that extends along the vertical direction when the operation portion 11 is pushed by a finger, and has a substantially M-shaped shape in a front view.

  The flat plate 117 has an inner side surface 117f facing the side wall 80w of the plug 8, and functions as a movable part that can move toward the side wall 80w by a pressing operation with a finger FG (see FIG. 4). Here, the inner side surface 117f of the flat plate 117 is formed as a relatively flat side surface.

<Operation of auxiliary tool 1A>
The operation of the auxiliary tool 1A will be described in detail with reference to FIG. 4 together with FIG.

  FIG. 4 is a diagram for explaining the operation of the auxiliary tool 1A. Here, FIG. 4 shows the auxiliary tool 1A that is elastically deformed by pressing the operation unit 11 toward the side wall 80w of the plug body 80 with two fingers (for example, thumb and forefinger) FG of one hand. When the finger FG of one hand is separated from the operation unit 11, the auxiliary tool 1A is restored to the basic shape shown in FIG. 2 by its own elasticity.

  As described above, the assisting tool 1A is provided with the deforming portion Tr1 having the bending section Bs in the operation portion 11. When the operation portion 11 is pressed toward the plug 8 with the finger FG, the bending section Bs is sandwiched between the flat plate 117 and the side wall 80w of the plug main body 80 (and the side plate 105 of the connection portion 10), and each bending portion Bs. The parts B1 to B3 are arranged on a substantially straight line. As a result, the bent section Bs extends straight and becomes flat, and the deformed portion Tr1 extends downward with respect to the plug 8. Here, the inner side surface 117f (FIG. 2) of the flat plate 117 plays an effective role in expanding the bent portions B1 to B3 in the obtuse angle direction and deforming them into a straight line, and smoothly straightens the bent section Bs. Will contribute. By such an extension operation of the deformable portion Tr1, the lower end (tip) of the deformable portion Tr1 protrudes downward while coming into contact with the upper surface 91f of the insertion port 91, and the amount of the protrusion, that is, the vertical direction of the deformable portion Tr1. The plug 8 is pushed up with respect to the outlet 9 in accordance with the increase amount (extension amount) of the length. In other words, in the state where the lower end 80e of the side wall 80w of the plug 8 and the upper surface (outer surface) 91f of the outlet 9 are close to each other, an operation input for pushing the operation unit 11 with the finger FG is performed, and thereby the side wall 80w of the plug body 80 is directed. A wave-like bent section Bs is sandwiched between the moving flat plate 117 and the side wall 80w and deformed into a straight shape, and along the deformation into the straight shape, the film extends along the vertical direction (Y-axis direction). The separation operation between the plug 8 and the outlet 9 is performed using the deforming portion Tr1 as a drive source. In this separation operation, since the pin 81 of the plug 8 is inserted into the hole 10h of the bottom 101 of the connecting portion 10 and the plug 8 and the auxiliary tool 1A are integrated, it is deformed by pushing into the operation portion 11. Even when vertical pressure is generated in the portion Tr1, the relative position of the upper end of the operation portion 11 with respect to the plug 8 does not substantially change. Therefore, the deforming portion Tr1 efficiently extends downward and can favorably press the outlet 9 relative to the plug 8. As shown in FIG. 4, when the operation unit 11 is crushed and completely deformed by the finger FG and the deformation unit Tr1 extends to the maximum protruding amount Lf, the lower end 117e (FIG. 2) of the flat plate 117 is The side plate 105 is preferably positioned in the vicinity of the lower end 105e (FIG. 2). In other words, when the deformation of the bent section Bs into the linear shape in the front view is completed, the lower end 105e of the side surface (side plate 105) on the plug 8 side adjacent to the deformed portion Tr1 and the lower end 117e of the side surface 117f of the flat plate 117. It is preferable that the (shortest) distances to the upper surface 91f of the outlet 9 are substantially equal. This is because when the line segment connecting the lower ends 105e and 117e is greatly inclined with respect to the upper surface 91f of the outlet 9 when the deformed portion Tr1 reaches the maximum protrusion amount Lf, the lower ends 105e, This is because the deformed portion Tr1 sandwiched between 117e tends to warp outward (in the direction away from the plug 8) or inward, and the plug 8 cannot be pushed up with respect to the outlet 9 efficiently. Here, if the maximum projecting amount Lf of the deformable portion Tr1 is equal to or larger than the separation distance necessary for pulling out the plug 8 (hereinafter also referred to as “necessary separation distance”), the portable type having the extension cable 99 (FIG. 1) is used. The plug 8 inserted into the outlet 9 can be completely pulled out with one hand (finger FG). However, even if the maximum protrusion amount Lf is slightly shorter than the required separation distance, the plug 8 is almost pulled out and can be completely pulled out using the other hand, etc. The disconnection between them can help.

  In the operation portion 11 of the auxiliary tool 1A that performs the above-described operation, the deformable portion Tr1 extends downward by pressing the finger FG toward the side wall 80w of the plug main body 80 as shown in FIG. The plug 8 can be pulled out (separated) from the outlet 9. Here, the pushing force of the plug 8 increases as the deforming portion Tr1 functions as a toggle mechanism (boost mechanism) and the bending section Bs approaches a straight line, so that the force necessary for extraction becomes a peak (maximum). If the straightness of the bending section Bs is increased in the vicinity of the push-up position of the plug 8, the plug 8 can be pulled out with a relatively small pressing force (operation input). In the operation unit 11 of the auxiliary tool 1A, since the deformed portion Tr1 is bent a plurality of times by the three bent portions B1 to B3, the overhang width Qa (FIG. 2) in the Z-axis direction is reduced, and the deformed portion A relatively large maximum protrusion amount Lf can be secured for Tr1. As a result, the separation operation assisting structure related to the operation unit 11 can be reduced in size. Furthermore, in the operation part 11 of the auxiliary tool 1A, since the overhang width Qa is small, a stroke (pushing operation amount) to be pushed with two fingers FG of one hand is small, which contributes to quick pulling out of the plug 8. .

  Moreover, in the operation part 11 of 1 A of auxiliary tools, since the distance of the upper and lower ends regarding each flat plate 112,113 is smaller than the flat plate 114, the structure regarding each flat plate 112,113 of the bending area Bs which leads expansion | extension operation | movement in deformation | transformation part Tr1. The portion can be effectively downsized. Furthermore, in the operation part 11 of the auxiliary tool 1A, since the distance between the upper and lower ends of the flat plates 112 and 113 is substantially equal, the structural portion of the flat plates 112 and 113 can be downsized in a well-balanced manner in the bending section Bs. As described above, the flat plates 112 and 113 having substantially the same length have substantially uniform forces generated during the pressing operation with the finger FG, so that the efficiency of strength design and the like is improved.

Second Embodiment
<Structure of essential parts of assisting tool>
FIG. 5 corresponds to FIG. 1 and is a perspective view showing a main configuration of an auxiliary tool 1B according to the second embodiment of the present invention. FIG. 6 corresponds to FIG. 2 and is a front view for explaining the configuration of the auxiliary tool 1B. And FIG. 7 is the figure which expanded the upper right part of the auxiliary tool 1B in FIG. In addition, the same referential mark is attached | subjected to what has the structure similar to 1st Embodiment.

  The auxiliary tool 1B is integrally formed of plastic, like the auxiliary tool 1A of the first embodiment, and is connected to the connection part 12 having a substantially U-shape when viewed from the front and the upper end of the connection part 12 And a pair of operation units 13 projecting in the ± Z direction.

  The connection part 12 has a configuration surrounding the plug main body 80 from three directions of the (± Z) direction and the (−Y) direction like the connection part 10 of the first embodiment, and is parallel to the XZ plane. A rectangular bottom plate 121 having a principal surface and a pair of side plates 125 coupled to both ends of the bottom plate 121 in the ± Z direction are provided.

  The bottom plate 121 is formed with two rectangular cutouts 12a and 12b through which the two pins 81 related to the plug 8 are inserted. Here, the notch 12a is notched from the back side (+ X direction side) in the bottom plate 121, but the notch 12b is notched from the front side (−X direction side), that is, from the direction opposite to the notch 12a. Yes. The thickness of the bottom plate 121 is thin enough not to affect the mechanical holding and electrical connection when the plug 8 is inserted into the outlet 9.

  Each of the pair of side plates 125 has a rectangular shape, and is configured as a flat plate extending from both ends of the bottom plate 121 in the vertical direction (+ Y direction). Note that the distance between the side plates 125 is set to be equal to or greater than the width of the plug body 80 in the Z-axis direction.

  Similar to the operation unit 11 of the first embodiment, the operation unit 13 is provided along each of the two side walls 80w of the plug main body 80, and covers the band-shaped inner part 131 that bends in a wave shape and the inner part 131 from the outside. A strip-shaped outer portion 137. Here, the width Wq of the operation portion 13 (the inner portion 131 and the outer portion 137) in the X-axis direction is set to be approximately equal to the width Wo of the side wall 80w.

  The inner portion 131 is provided with a bent section Bt (a section from the uppermost bent portion C1 to the lowermost bent portion C5) having five bent portions C1 to C5 along the side wall 80w. More specifically, in the inner portion 131, a wave-like bent section Bt having five bent portions C1 to C5 whose bending directions are alternately reversed downward is formed by a flat plate 139 (described later) of the outer portion 137 and the plug body. It is provided between 80 side walls 80w.

  The inner portion 131 includes a rectangular flat plate 132 connected to the bent portion C1 and the bent portion C2, a rectangular flat plate 133 connected to the bent portion C2 and the bent portion C3, a bent portion C3, and a bent portion C4. And a rectangular flat plate 134 connected to each other. Further, the inner portion 131 includes a rectangular flat plate 135 connected to the bent portion C4 and the bent portion C5, and the vicinity of the upper surface 91f (FIG. 6) of the insertion port 91 downward from the lower end of the bent portion C5, in other words. And a rectangular flat plate 136 extending to the vicinity of the lower end 80e of the side wall 80w. That is, the inner portion 131 is provided with four flat plates 132 to 135 whose upper ends and lower ends are connected to two adjacent bent portions having opposite bending directions among the five bent portions C1 to C5. A flat plate 136 having upper and lower ends composed of a lower end and a connection end connected to the bent portion C5 closest to the lower end is provided.

  In the inner portion 131, the lengths of the flat plates 132 to 135 in the vertical direction are set to be approximately equal, while the flat plate 136 is longer than the flat plates 132 to 135. Further, the flat plate 136 is set to be longer than the maximum protruding amount Lg (see FIG. 8) when the tip of the inner portion 131 protrudes downward. This is because the lowermost bent portion C5 protrudes from the lower end 125e of the side plate 125 (the lower end surface of the bottom plate 121) when the operation unit 13 is pressed toward the side wall 80w of the plug body 80 as described later. This is because if it is positioned in the vicinity of the lower end 125e, it is difficult to transmit the downward force (the push-up force of the plug 8) by bending at the bent portion C5. Further, an angle θe formed by the flat plate 132 and the flat plate 133, an angle θf formed by the flat plate 133 and the flat plate 134, and an angle θg formed by the flat plate 134 and the flat plate 135 are each set to about 60 °. On the other hand, the angle θh formed by the flat plate 135 and the flat plate 136 is set to an obtuse angle.

  The outer portion 137 has one bent portion C7, and a rectangular upper plate 138 connected to the bent portion C7 (and the bent portion C1) and the upper end of the side plate 125, and extends downward from the bent portion C7. And a rectangular flat plate 139 configured as a straight section Ft substantially parallel to the side plate 125 and the side wall 80w of the plug main body 80. Here, the angle θq formed by the upper plate 138 and the side plate 125 is set to about 60 °.

  As shown in FIG. 7, the upper plate 138 is shaped so as to increase in proportion to the distance from the side plate 125 in a front view, and is bent with the bent portion C1 provided at the upper end portion of the inner portion 131. It is connected to part C7. Here, an angle θi formed by the upper plate 138 and the flat plate 132 of the inner portion 131 is set to about 60 °. The upper plate 138 and the inner portion 131 function as a deforming portion Tr2 that extends along the vertical direction when the operation portion 13 is pushed by a finger.

  The flat plate 139 has an inner surface 139f that faces the side wall 80w of the plug 8, and functions as an input unit that accepts a pressing operation by a finger FG (see FIG. 8) and a movable unit that can move toward the side wall 80w. Here, the inner side surface 139f of the flat plate 139 is formed as a relatively flat side surface.

<Operation of auxiliary tool 1B>
The operation of the auxiliary tool 1B will be described in detail with reference to FIG. 8 together with FIG.

  FIG. 8 is a diagram for explaining the operation of the auxiliary tool 1B. Here, FIG. 8 shows the auxiliary tool 1B that is elastically deformed by pressing the operation unit 13 toward the side wall 80w of the plug body 80 with two fingers FG of one hand. When the finger FG of one hand is separated from the operation unit 13, the assisting tool 1B is restored to the basic shape shown in FIG. 6 by its own elasticity.

  As described above, the assisting tool 1B is provided with the deforming part Tr2 having the bending section Bt in the operation part 13. When the operation portion 13 is pressed toward the plug 8 with the finger FG, the bending section Bt is sandwiched between the flat plate 139 and the side wall 80w of the plug body 80 (and the side plate 125 of the connecting portion 12), and each bending portion Bt is The parts C1 to C5 are arranged substantially on a straight line. As a result, the bent section Bt extends straight and becomes flat, and the deformed portion Tr2 extends downward with respect to the plug 8. Here, the inner side surface 139f (FIG. 6) of the flat plate 139 plays an effective role in expanding the bent portions C1 to 5 in the obtuse angle direction and deforming them in a straight line, and smoothly straightens the bent section Bt. Will contribute. By such an extension operation of the deformable portion Tr2, the upper surface 91f of the insertion port 91 is pressed against the lower end of the deformable portion Tr2, as in the first embodiment, and the plug 8 is pushed against the outlet 9 according to the extension amount. Raising is done. That is, by performing an operation input of pushing the operating unit 13 with the finger FG in a connected state where the outlet 9 is close to the plug 8, the flat plate 139 moving toward the side wall 80w of the plug body 80 and the side wall 80w A wave-shaped bending section Bt is sandwiched between the plug 8 and the outlet 9, and the plug 8 and the outlet 9 are separated from each other by using the deforming portion Tr2 extending along the vertical direction as the driving force is deformed. Will be performed. As shown in FIG. 8, when the operation portion 13 is crushed and completely deformed by the finger FG and the lower end of the deformation portion Tr2 protrudes to the maximum protrusion amount Lg, the flat plate 139 is formed as in the first embodiment.

Can be reduced in size. As a result, the separation operation assisting structure related to the operation unit 13 has a projecting width Qb (FIG. 6) in the Z-axis direction that is smaller than that of the first embodiment, and can be further reduced in size. Furthermore, in the operation part 13 of the auxiliary tool 1B, the pushing operation amount corresponding to the overhanging width Qb is smaller than that in the first embodiment, so that a quicker separation operation is possible.

  Moreover, in the operation part 13 of the auxiliary tool 1B, since the distance between the upper and lower ends of the flat plates 132 to 135 is smaller than the flat plate 136, the flat portions 132 to 135 of the bending section Bt having a high influence on the extension operation in the deforming portion Tr2. The structural portion can be effectively downsized. Furthermore, in the operation part 13 of the auxiliary tool 1B, since the distance between the upper and lower ends of the flat plates 132 to 135 is substantially equal, the structural portion of the flat plates 132 to 135 can be downsized in a well-balanced manner in the bending section Bt.

  Further, in the auxiliary tool 1B, the reinforcing plate 103 provided in the connecting portion 10 of the first embodiment is omitted, and the two notches 12a and 12b through which the pins 81 of the plug 8 are inserted are reversed in the bottom plate 121. It has a structure that is cut out from the direction. With such a simplified structure, the apparatus and method (process) for manufacturing the auxiliary tool 1B can be simplified.
