  The plug removal prevention tool according to the present embodiment is used to prevent removal of the plug 31 from the socket of the electronic device 30. The plug removal prevention tool, as shown in FIGS. 1 to 3, comprises a rectangular cylindrical base member 10 fixed to the electronic device 30 and a holder 20 formed of a wire.

  As shown in FIG. 2, the base member 10 is an angular tubular member that covers four sides by the upper wall 11, the lower wall 12 and the pair of side walls 13, and the holder 20 can be inserted by opening the end. The opening 14 is formed. As shown in FIG. 3, the base member 10 is fixed to the electronic device 30 in a state where the lower surface of the lower wall 12 is in contact with the surface of the electronic device 30. The mounting position of the base member 10 is a position where the socket of the electronic device 30 comes on the extension of the opening 14 of the base member 10. Although the method of fixing the base member 10 to the electronic device 30 is not particularly limited, for example, if the adhesive seal or the like is provided on the surface of the lower wall 12, the base member 10 can be easily fixed to the electronic device 30.

  As shown in FIG. 2 (b), engagement holes 15 are provided in the pair of side walls 13 of the base member 10. The engagement holes 15 are bored at positions opposite to each other in the pair of side walls 13 in such a size that an engagement portion 22 described later can be engaged.

  The holder 20 is formed of a wire such as a wire and is elastically deformable. As shown in FIG. 1, the holder 20 is a U-shaped hook formed by bending a pair of extending portions 21 which can be inserted into the inside of the base member 10 and an end portion of the pair of extending portions 21. And a unit 25.

  As shown in FIG. 1A, the pair of extending portions 21 are formed so as to open slightly outward in the distal direction. Ideally, the distance between the pair of extending portions 21 is larger at the widest point (tip side) than the distance between the pair of side walls 13 of the base member 10, and the narrowest point (non-tip side) A gap smaller than the gap between the pair of side walls 13 of the base member 10 is formed.

  The pair of extending portions 21 are provided with an engaging portion 22 that protrudes outward, and an overhanging portion 23 that protrudes outward at a point opposite to the distal end side of the engaging portion 22.

  As shown in FIG. 1A, the engaging portion 22 is formed in an arrowhead shape in plan view. That is, the tip end side of the engaging portion 22 is an inclined surface 22 a inclined with respect to the extending direction of the extending portion 21, and the opposite end side of the engaging portion 22 is the extending direction of the extending portion 21 The rising surface 22b is substantially perpendicular to the upper surface 22b. One engaging portion 22 is provided in each of the pair of extending portions 21. The pair of engaging portions 22 project outward beyond the distance between the pair of side walls 13 of the base member 10.

  The overhanging portion 23 is provided to face the opening 14 of the base member 10 when the pair of extending portions 21 is inserted into the base member 10. One projecting portion 23 is provided in each of the pair of extending portions 21. The pair of projecting portions 23 project outward more than the distance between the pair of side walls 13 of the base member 10.

  When using this plug removal prevention tool, as shown in FIG. 3, the cable 33 of the plug 31 is hooked on the U-shaped hook 25 and the extension 21 is inserted from the opening 14 of the base member 10. At this time, if necessary, the pair of extending portions 21 are elastically deformed inwards by manually pinching them from both sides. When the extending portion 21 is inserted, the opening 14 abuts on the inclined surface 22 a of the engaging portion 22, and the pair of extending portions 21 elastically deform inward, whereby the engaging portion 22 is opened. Pass through. When the extending portion 21 is inserted to a position where the engaging portion 22 engages with the engaging hole 15, the rising surface 22 b is caught in the engaging hole 15, so the holder 20 does not come off the base member 10. At this time, the hooking portion 25 holds the root 32 of the plug 31 so as not to be detached from the electronic device 30. Thus, the plug 31 is prevented from coming off. In addition, since the plug 31 is reinforced by the holder 20, for example, even when a force is applied to the plug 31 in a lateral direction, the holder 20 receives the force, so that the plug 31 is prevented from being bent or broken. Can.

  Moreover, as shown in FIG. 3B, since the overhanging portion 23 faces the opening 14 of the base member 10, the overhanging occurs even when a force acts on the base member 10 so as to swing the holding tool 20 left and right. The portion 23 abuts against the opening 14 of the base member 10 to prevent rattling of the holder 20. Therefore, for example, even if a force is applied to pull the plug 31 obliquely, the plug 31 can be prevented from coming off.

  When it is desired to remove the plug 31 from the electronic device 30, the holder 20 may be removed from the base member 10. That is, since the engaging portion 22 can be removed from the engaging hole 15 if the pair of extending portions 21 are elastically deformed inward by hand-picking from both sides, the holder 20 may be pulled out in this state. .

  In the example shown in FIG. 3, the plug removal prevention device is used for the I-shaped plug 31 in which the root 32 of the plug 31 extends in the same direction as the cable 33. However, the present invention is not limited thereto. As shown, the same plug removal prevention device can be used for the L-shaped plug 31 in which the root 32 of the plug 31 is orthogonal to the cable 33. In the case of using the L-shaped plug 31, the hook 32 may hold down the root 32 of the plug 31 without hooking the cable 33 of the plug 31 to the hook 25.

  The present embodiment is as described above, and the holder 20 is a U-shaped member formed by bending the end portions of the pair of extending portions 21 that can be inserted into the inside of the base member 10 and the pair of extending portions 21. A pair of extending portions 21 are provided with engaging portions 22 that project outward, and on both sides of the base member 10, engaging holes in which the engaging portions 22 can be engaged. 15 are provided. According to such a configuration, the holder 20 can be attached to the base member 10 by engaging the engaging portion 22 with the engaging hole 15. At this time, if the plug 31 is held down by the U-shaped hook 25, the plug 31 can be prevented from coming off. When it is desired to pull out the plug 31, the pair of extension portions 21 are elastically deformed in the direction in which they approach each other by holding the pair of extension portions 21 by hand so that the engagement portion 22 is engaged from the engagement hole 15. It can be removed. The holder 20 can be removed from the base member 10 by pulling the holder 20 out of the base member 10 in this state. As described above, since the holder 20 is made to be removable from the base member 10 by being elastically deformed, it is possible to provide a plug removal prevention device that is suitable for repeated use and hardly generates a sound at the time of the removal.

  In addition, the engaging portion 22 is formed in an arrowhead shape in plan view. According to such a configuration, when engaging the engaging portion 22 with the engaging hole 15, the arrowhead-shaped inclined surface 22a is pushed by the base member 10, and the pair of extending portions 21 gradually approach each other Because of the elastic deformation, the mounting of the holder 20 is easy. Further, in the state in which the engaging portion 22 is engaged with the engaging hole 15, the rising edge 22b of the arrowhead shape engages with the base member 10, so that the holder 20 can be effectively prevented from falling off.

  Further, when the pair of extending portions 21 is inserted into the base member 10, the overhanging portion 23 faces the opening 14 of the base member 10. According to such a configuration, after the holder 20 is attached to the base member 10, the overhanging portion 23 contacts the opening edge of the base member 10 even if a force is applied to shake the holder 20 to the left and right. The rattling to the left and right of the holder 20 can be prevented. Therefore, it is possible to prevent the plug 31 from coming off due to back and forth movement.

  In addition, it is good also as an aspect as shown not only in above-described embodiment but in FIG. In the embodiment shown in FIG. 5, the pair of extending portions 21 is provided with a protruding portion 24 that protrudes outward on the opposite end side of the engaging portion 22. One each of the protruding portions 24 is provided in the pair of extending portions 21. The pair of projecting portions 24 project outward substantially the same as the distance between the pair of side walls 13 of the base member 10. In the plug removal prevention device shown in FIG. 5, when the pair of extending portions 21 is inserted into the base member 10, the supporting portion 24 is pressed against the inner wall 17 of the base member 10. According to such a configuration, after the holder 20 is attached to the base member 10, even if a force that shakes the holder 20 is applied to the left and right, the supporting portion 24 contacts the inner wall 17 of the base member 10. The rattling to the left and right of the holder 20 can be prevented. Therefore, it is possible to prevent the plug 31 from coming off due to back and forth movement.

  Moreover, you may use the holder 20 as shown to Fig.6 (a). The holder 20 does not have the projecting portion 23 or the supporting portion 24 and can have a simple structure.

  Moreover, you may use the holder 20 as shown in FIG.6 (b). The holder 20 is provided with a plurality of engaging portions 22 in the extending portion 21. If a plurality of engagement holes 15 are provided also in the base member 10 to which the holder 20 is attached, the holder 20 is difficult to be disengaged by engaging the plurality of engaging portions 22, so the plug 31 can be prevented from coming off Can be enhanced.

  Moreover, you may use the holder 20 as shown in FIG.6 (c). The engaging portion 22 of the holder 20 has a substantially semicircular shape in plan view, not an arrowhead shape. Even with such a holder 20, the plug 31 can be prevented from coming off.

  Further, as shown in FIG. 7, the opening portion 14 of the base member 10 may be provided with a folded back portion 16 for narrowing the opening. According to such a configuration, when the holder 20 is engaged with the folded portion 16, the holder 20 is difficult to be removed and it is difficult to rattle from side to side, so the effect of preventing the plug 31 from being removed can be enhanced. .

  Further, as shown in FIG. 8A, a plurality of engagement holes 15 may be provided in the base member 10. In addition, in the holder 20, only one engaging portion 22 may be provided in each of the extension portions 21. According to such a configuration, the degree of protrusion of the hook portion 25 can be changed stepwise by changing which engaging hole 15 is engaged. For example, when the size of the plug 31 is large, as shown in FIG. 8B, the engagement portion 22 may be engaged with the nearest engagement hole 15 to increase the degree of projection of the hook portion 25. . Further, when the size of the plug 31 is medium, as shown in FIG. 8C, the engagement portion 22 is engaged with the intermediate engagement hole 15, and the degree of protrusion of the hook portion 25 is set to be medium. Just do it. When the size of the plug 31 is small, as shown in FIG. 8D, the engagement portion 22 may be engaged with the deepest engagement hole 15 to reduce the degree of projection of the hook portion 25. This makes it possible to cope with a plurality of plugs 31 of different sizes.

  Moreover, you may provide the stopper 40 for suppressing so that it can not elastically deform in the direction which a pair of extension parts 21 inserted in the inside of the base member 10 mutually approach. Although various shapes can be considered as a shape of the stopper 40, For example, a shape as shown in FIG. 9 may be sufficient. The stopper 40 shown in FIG. 9 includes an insertion portion 42 which can be inserted into the base member 10 and a head 41 which is formed to have a cross-sectional area larger than the insertion portion 42 and can not be inserted into the base member 10. The stopper 40 is inserted into the base member 10 in a direction opposite to the insertion direction of the extending portion 21 as shown in FIG. 10A. When the stopper 40 is inserted into the base member 10, as shown in FIG. 10 (b), the tip of the stopper 40 (the tip of the beveled insertion portion 42) gets in between the pair of extending portions 21, and the pair It prevents the elastic deformation of the extension portions 21 in the direction in which they approach each other. By attaching the stopper 40 in this manner, the pair of extending portions 21 can be elastically deformed so that the operation of removing the engaging portion 22 from the engaging hole 15 can not be performed. That is, since the stopper 40 can lock the holder 20 so that the holder 20 can not be removed, it is possible to prevent the holder 20 from being detached from the base member 10 unintentionally.

  When it is desired to release the lock by the stopper 40, the stopper 40 may be removed from the base member 10. The removal of the stopper 40 can be easily performed, for example, by using a removal tool 45 as shown in FIG. The removal tool 45 according to the present embodiment is a rod-like member longer than the base member 10, and as shown in FIG. 11A, a direction different from the insertion direction of the stopper 40 (ie, a pair of extending portions 21).
