  The type of plug and the outlet into which it is plugged differ from country to country.When traveling abroad, in order to use Japanese electrical products in each country, you must possess a conversion plug that matches the outlet in the country where you are staying. When staying in multiple countries, a conversion plug for each country is required.

  One method for solving these problems is a V-shaped plug (Japanese Patent Laid-Open No. 9-289066). A Japanese-style outlet into which a Japanese-style plug provided on the V-shaped plug is inserted is a V-shaped plug. When a Japanese plug is inserted, it will be inserted in an oblique state, and when using heavy electrical products such as a plug with voltage conversion and a shaver with a plug used for a laptop computer. In such a case, there was a risk that the plug terminal would be subjected to an excessive unbalanced load and the plug terminal could come off or the plug or the main body could be damaged.

On the horizontal line connecting the two rotation axes, a movable plug terminal is penetrated and fixed at a position that is eccentric to the same distance that is symmetrical with respect to each rotation axis. According to the eccentric position, the distance between the two movable plug terminals changes and can be adjusted. Since the pair of rotating bodies are in mesh or in close contact with each other, when one of the rotating bodies is rotated, the other is rotated by the same distance, and the pair of movable plug terminals connect both rotation axes of the rotating bodies. The movable plug terminal moves in parallel with the waterside line while changing the distance between the movable plug terminals. In addition, one end of the C-shaped winding spring is fixed to the spring fixing shaft in the middle position between the two rotating bodies at the upper part of the plug body, the coil portion at the center of the winding spring is wound around the rotating shaft, and the other end is Attached to the circumferential one side of the movable plug terminal. When the rotating body is rotated by the rotary knob by the urging force of the winding spring, the pair of movable plug terminals move and the distance between the terminals changes, but when the rotary knob is released, it can return to the original position. Control of the moving distance of the movable plug terminal is regulated by the length of the movable plug terminal moving groove provided on the cover or the length of the rotary knob moving groove. Synthetic rubber or the like may be provided on the outer circumferences of both rotating bodies, the rotating bodies may be joined together, and may be rotated synchronously by the frictional force therebetween (FIGS. 1, 2, 3, and 4).

On the horizontal line connecting the two, the integral plug terminal is detachably inserted at a position that is eccentric to the same distance symmetrical with respect to each rotation axis, and a pair of the integral plug terminals is formed by rotation of the rotating body. According to the eccentric position, the distance between the two integrated plug terminals changes and can be adjusted. Since the pair of rotating bodies are in mesh or in close contact with each other, when one of the rotating bodies is rotated, the other is rotated by the same distance. It moves by changing the distance between the integrated plug terminals in parallel with the connected waterside line. In addition, one end of the C-shaped winding spring is fixed to the spring fixing shaft in the middle position between the two rotating bodies at the upper part of the plug body, the coil portion at the center of the winding spring is wound around the rotating shaft, and the other end is Attached to the circumferential one side of the integral plug terminal. When the rotating body is rotated by the rotary knob by the urging force of the winding spring, the pair of integrated plug terminals move and the distance between the terminals changes. However, when the rotary knob is released, it can return to the original position. Control of the movement distance of the integral plug terminal is regulated by the length of the movable plug terminal movement groove provided on the cover or the length of the rotary knob movement groove. Synthetic rubber or the like may be placed on the outer periphery of both rotating bodies, the rotating bodies may be joined together, and rotated synchronously by the frictional force therebetween (FIGS. 12, 13, 14, and 15).
