Description

  The present invention relates to an AC cord drop prevention device for an AC adapter that prevents an AC cord inserted into an AC adapter from easily falling off the AC adapter.

  In general, an AC adapter that is used by inserting an AC cord into an AC inlet does not include an AC cord drop prevention tool for preventing the AC cord from easily falling off the AC inlet. In recent years, even if an AC adapter is used as a power source for equipment or facilities that are important or require high reliability, an AC cord fall prevention tool is increasingly required, and the AC cord can be securely dropped. There is a need for a drop-off prevention tool that can prevent this.

Japanese Patent Application No. 2009-273933

An AC cord plug inserted into the AC inlet of the AC adapter is hung around the AC adapter with a strength band so that the AC cord plug does not easily fall out of the AC adapter, and both ends thereof are locked to the AC cord plug. A drop-off prevention tool that has been fastened on the belt feed bracket of the fixture has already been developed, but using a substantially U-shaped capture part in which the press bracket surrounds the cord root on the plug of the AC cord from the three surrounding directions, When the remaining opening in one direction is used for attachment / detachment, the presser bracket is pressed with a strong force in the direction of the U-shaped closed from the opening side. There was a possibility of sliding off the plug.
In addition, the cloth band to be folded and tightened through the belt feed bracket should be the front band to be folded back when the surface of the fabric band is smooth and the belt feed bracket can be freely rotated around the arm of the holding bracket. When pulling with a strong force, sometimes loosened.
In view of the above, in the present invention, when the fall prevention device is attached to the AC adapter, the press fitting does not slide down from the plug of the AC cord even if the press fitting is pressed with any force from any direction. In addition to pulling back the fabric band on the back side through the metal fittings, the fabric band will not loosen even if the front fabric band folded back is pulled with a strong force, and the metal fittings will not slide down from the AC cord plug. An object of the present invention is to provide a fixing tool for an AC cord drop-off prevention device that does not easily fall out of an AC inlet of an AC adapter.

In order to achieve the above object, the retainer of the fixing tool for the AC cord drop prevention tool for the AC adapter according to the present invention hangs a strong cloth band around the AC adapter, and both ends thereof are used as the belt feeding bracket of the fixing tool. In a fixture for preventing the AC cord from falling out of the AC adapter by locking and tightening,

(6) An oblong hole that allows the lock fitting to move freely with respect to the presser fitting when the wire of the presser fitting is passed through one end of the substantially rectangular longitudinal direction may be provided.
The fittings are

(7) Two bent metal plates with two or four rectangular pieces that stand up perpendicular to each long side and face each other and screwed with two screws are two pieces for one holding bracket. Used,
(8) The four rectangular pieces are provided with two concave portions that are aligned with a portion perpendicular to the arm portion of the presser fitting between two adjacent surfaces excluding the central portion,
(9) Each of the rectangles rising vertically to the substantially rectangular surface is a double overlap in a state where the substantially rectangular portion is fixed by screwing,
(10) Between the two substantially rectangular surfaces, the arm portion near the end of the presser fitting and one side which is the belt feed fitting coupling side of the feed fitting can be closely attached and sandwiched. ,
(11) The arm portion of the presser fitting can be rotated around the arm portion, but the rotation angle is limited by the recess.
Here, the belt feed bracket that the coupling bracket connects to the holding bracket is

(12) A commercially available belt feed bracket called Kokikan or Senkoki may be used.
(13) When a fixture using a cloth band with a hook and loop fastener is required, it may be a quadrangular square can having no movable part called a kakukan.

  In the fixing device of the present invention, the lock metal fitting is passed through an oblong hole provided at one end of the lock metal fitting, and the coupling metal fitting is attached to the arm portion near both longitudinal ends of the metal fitting. There is no worry of losing without detaching from the presser bracket.

  In addition, since the lock fitting can be moved freely on the press fitting before the AC cord drop prevention device is attached to the AC cord of the AC adapter, the opening side of the substantially U-shaped capturing portion of the press fitting is attached to the plug of the AC cord. Does not get in the way when attached to the root.

  Further, when the presser fitting is hung on the AC cord plug, the horizontal stabilizing piece is placed on the shoulder on the AC cord plug and pressed by both legs of the substantially U-shaped catching portion of the presser foot, and the lock piece is placed on the catching portion. The locking piece is stable in position with respect to the AC plug by hooking the vertical stabilizing piece to the cord root on the plug of the AC cord, by hooking the protruding portion bent at right angles from both open ends. Since the lock fitting and the catching portion are integrated to catch the cord base on the plug from four directions, the press fitting does not slide off from the plug by a strong force from any direction.

  In addition, since the joint bracket is a recess provided in two places on the side of the retainer bracket, and the rotation of the joint bracket with the arm portion of the retainer bracket as an axis is within a limited angle range, after being folded over the movable part of the belt feed bracket The fabric band on the side is strongly pressed between the belt feed bracket and the fabric band before passing through the belt feed so that it will not loosen even if the fabric band before or after folding is pulled strongly.

  The six rectangular pieces of coupling metal fittings that apply strong force when they are tightened tightly with a cloth band are assembled in a double structure so that they are difficult to deform, and at the same time, you can use a commercially available Kokikan as a belt feeding metal fitting, thus fixing the cost The manufacturing cost can be kept low.

  Furthermore, in applications where there is no concern that a strong force will be applied to the load band, if you want to use a cloth band with a hook-and-loop fastener that is convenient for easy attachment and detachment, priority is given to convenience. It can be easily replaced with a wire fitting for folding a cloth band having no movable part.
