JP-A-6-5331

  The problem to be solved by the present invention is that in order to attach the above-described plug disconnection prevention device to an electrical device, a fastening tool must be used instead of the screw fixing the inlet, and the electrical device is purchased. It is difficult for users to install, and it must be installed by the manufacturer of the electrical equipment or the engineer of the store that sells the electrical equipment, and there is a problem that it cannot be retrofitted, and the current electrical equipment cannot be easily installed. Met.

  The present invention solves the above problems and provides a plug removal prevention device that can be easily retrofitted to an electric device without requiring a special tool or technique by a user who already uses the electric device. This is the issue.

In order to solve the above-mentioned problems, a plug removal prevention device according to the present invention is characterized by having the following requirements for preventing a plug inserted into an inlet of an electrical device from being removed.
(A) The plug removal prevention device includes a fixing plate attached to the outer wall surface of the electric device, and a clamper that is rotatably attached to the fixing plate and engages / disengages with the plug inserted into the inlet. (B) The fixing plate is formed with an opening for exposing the inlet, and a first fixing plate for rotatably supporting the clamper, and attachment means such as a double-sided adhesive tape on the outer wall surface of the electric device (C) The fixed plate is formed by orthogonally crossing the first fixed plate and the second fixed plate.

  Preferably, the first fixing plate is provided with a plurality of shaft holes for supporting the clamper so that the mounting position on the first fixing plate can be changed.

  According to the first aspect of the present invention, the fixing plate can be easily attached to the outer wall surface of the electric device without using a tool, and the plug can be prevented from coming off.

  Moreover, since the plug pulling direction and the fixing plate peeling direction are orthogonal to each other, the mounting state of the fixing plate to the electrical device is strong with respect to the plug pulling direction, and it has a great effect in preventing the plug from being pulled out. be able to.

  According to the second aspect of the present invention, it is possible to provide the plug removal preventing apparatus A that can flexibly correspond to the position of the inlet provided in the electric device.

  FIG. 1 shows an example of a plug removal prevention device according to the present invention, which is engaged with a fixing plate 1 fixed to a wall surface of an electric device, and a plug rotatably attached to the fixing plate 1 and inserted into an inlet. And a clamper 2 that performs the above operation. As shown in FIG. 2, the fixing plate 1 is bent at a right angle in an L shape in a plan view, and is composed of two fixing plates, a first fixing plate 1a and a second fixing plate 1b. The fixing plate 1a is formed with an opening 3 cut into a substantially U shape for exposing the inlet, and both side portions of the opening 3 bulge outward to form a wall portion 4, and this wall portion 4 is formed. Is formed with a shaft hole 5 that supports a rotating shaft 11 of the clamper 2 described later. A double-sided adhesive tape in which an adhesive layer is provided on both sides of the tape as the attachment means 6 is attached to the inner side surface of the second fixing plate 1b.

  As shown in FIG. 2, the clamper 2 includes an engagement portion 10 that bends an elastic metal wire into a substantially U-shape and further folds the tip side from a substantially central portion into a substantially L shape to engage the plug. The rotating shaft 11 is formed by bending both ends outward, the rotating shaft 11 is inserted into the shaft hole 5 of the fixed plate 1, and the clamper 2 is rotated in the forward and reverse directions with respect to the fixed plate 1. Thus, the engaging portion 10 of the clamper 2 can be engaged with and disengaged from the plug.

  When attaching the plug removal prevention device A to the electric device B, as shown in FIG. 3A, the fixing plate 1 is placed so that the inlet 15 of the electric device B is accommodated in the opening 3 of the first fixing plate 1a. The second fixing plate 1b is pressed against the side surface of the electric device B while checking the vertical position. Since the double-sided adhesive tape 6 is affixed to the inner surface of the second fixing plate 1b, the fixing plate 1 is attached to the inlet 15 by the double-sided adhesive tape 6 as shown in FIG. It fixes to the wall surface of the electric equipment B in the state exposed from the opening part 3 of the fixing plate 1a.

  In this way, when the plug disconnection prevention device A is attached to the electric device B and the plug 17 of the power cord 16 is inserted into the inlet 15 of the electric device B as shown in FIG. As shown in FIG. 5 (b), the clamper 2 is rotated in the direction of arrow a so that it does not interfere with the progress of the plug, and then the plug 17 is inserted into the inlet. Is rotated in the direction of arrow b to engage the engaging portion 10 with the back of the plug 17.

  In a state where the engaging portion 10 of the clamper 2 is engaged with the back of the plug 17, as shown in FIG. 4B, the engaging portion 10 of the clamper 2 is in a state of preventing the plug 17 from being pulled out. Even if a force is applied in such a direction that the plug 17 is pulled out of the inlet due to an external force applied to the power cord, the plug 17 is not caught by the clamper 2.

  At this time, force is also applied to the fixing bracket in the direction of arrow c (see FIG. 5B). However, the fixing bracket is fixed to the wall surface of the electric device with the double-sided adhesive tape 6, and the direction in which the fixing bracket is pulled off is the arrow d direction. For this reason, the direction in which the fixing bracket is pulled off and the external force applied to the fixing bracket are in the direction of arrow c and are orthogonal to each other. Therefore, the fixing bracket cannot be separated from the electrical device by the external force in the direction of pulling out the plug 17. In addition to being easily fixed with the adhesive tape 6, it is possible to realize a fixing bracket that is strong against peeling.

  FIG. 6 shows another example of the plug removal prevention device A. This plug removal prevention device A has a plurality of shaft holes 5 into which the rotation shaft 11 of the clamper 2 is inserted in the wall portion 4. The position of the clamper 2 may be changed corresponding to the above. Accordingly, it is possible to provide the plug removal prevention device A that can flexibly correspond to the position of the inlet provided in the electric device.
