Description

  The present invention relates to a plug with a switch, and more particularly, to a plug with a high practical function, in which a switch is added to the plug to reduce danger in use operation.

  In this era, electric appliances are operated by plugging in power for both consumer and industrial use. The plug includes one in which the blade is sandwiched between the upper and lower cases with screws, and the other in which the blade and the electric wire are molded and combined with the plug to be integrated. In the former, the bipolar blade is apt to be loosened, and a poor contact is easily formed. The latter is molded and has stability at the time of plug-in use, but since the plug body is not provided with a current opening / closing device, a spark may be generated at the moment when the blade directly rubs when plugging and unplugging. . In addition, the blade of the plug is easily exposed to the humidity in the air and easily generates static electricity, and if the wire length is insufficient, it must be plugged and unplugged from an extension outlet, increasing the chance of electric shock. From the above, well-known plugs are required to be improved.

The main purpose of the present invention is to provide a kind of plug with switch. It is a plug with a high practical function in which a blade, a resistor, an LED, a guide plate, a switch, a cover and a base are combined, and a switch is added to the plug to reduce a danger in use operation.
A second object of the present invention is to provide a kind of plug with a switch, which is selectively connected to a power source through a square piece and a guide plate at the bottom of a receiving chamber provided in the plug body. It is assumed that a connecting piece is provided, a switch is provided with a telescopic shaft urged by elastic means, and the telescopic shaft slides and expands and contracts along an arc trajectory of the guide plate.
Another object of the present invention is to provide a kind of plug with a switch, in which a guide plate is pivotally mounted on a plug body in a seesaw shape, and a protruding end of a telescopic shaft abuts on an arc trajectory of the guide plate. It slides and provides a function of switching between the left and right levers when reciprocating.
Another object of the present invention is to provide a kind of plug with a switch, in which a telescopic shaft urged by elastic means reciprocates and expands and contracts along an arc trajectory of a guide plate, and is guided by a piston movement of the telescopic shaft. It shall adapt to the seesaw movement when switching the boards.
It is another object of the present invention to provide a kind of plug with a switch, in which an energized state of the plug can be confirmed by an LED, and the switch is covered by a cover to achieve a waterproof function.

The invention of claim 1 is a plug with a switch in which a blade, a resistor, an LED, a guide plate, a switch, a cover and a base are combined,
A housing having an open side surface is formed on one side of the inside of the plug body obtained by combining the upper body and the lower body, and a single-pole blade is provided in the plug body in a groove provided in the plug body. And a connection piece and an electric wire connected thereto are accommodated, and another groove parallel to the groove accommodates another pole blade and a rectangular piece corresponding to the connection piece connected thereto and the electric wire connected thereto. Grooves A and B are provided, the wires drawn out from the joint ends of the two wires are connected to the LED and the resistor, and the LED is housed in the housing provided in the plug body, and on the bottom surface of the housing chamber, A square piece and a connection piece with a convex circle formed integrally are arranged, the square piece and the connection piece are selectively connected via a guide plate, and the switch has a middle hole in the center and elastic in the hole Means is provided, and a telescopic shaft biased by the elastic means is provided at the end. Vignetting, the telescopic shaft is elastically protrude in the receiving chamber, characterized in that it abuts on the circular arc track of the guide plate, and a switch with a plug.
According to a second aspect of the present invention, in the plug with the switch according to the first aspect, the guide plate has two wings, and the upper and lower concave portions at the center are fitted and supported by the plug main body to exhibit a seesaw shape swinging in both directions. A plug with a switch, characterized in that the protruding end of the shaft has an arc shape and forms a switch change when reciprocating along a guide plate.
According to a third aspect of the present invention, in the plug with the switch according to the first aspect, an operation in which the elastic means provided on the switch reciprocates along the undulation of the arc trajectory of the guide plate corresponds to switch switching. Features a plug with switch.

  In the present invention, the switch is provided on the plug, so that the switch can be turned on after the switch is turned off and the plug is inserted and removed, thereby preventing sparks from being generated and preventing static electricity from danger to the body. Can be prevented.

  As shown in FIGS. 1 to 5, the plug with a switch according to the present invention includes a combination of a blade, a resistor, an LED, a guide plate, a switch, a cover, and a base. The plug includes an upper main body 5 and a lower main body 55 that are molded, and a housing chamber 551 having an open side surface is formed on one side of the plug main body formed by merging the upper main body 5 and the lower main body 55. . In the plug body, the blade 52 and the connection piece 53 and the electric wire 535 connected thereto, the other pole blade 56 and the connection piece 556 connected thereto, and the square piece 57 corresponding to the connection piece 556 and connected thereto. Grooves A and B for accommodating the electric wires 557 are provided, the electric wires are connected to the coupling ends of the two currents, connected to the LED 58 and the resistor 59, and the LED 58 is accommodated in the accommodating portion 552 provided on the plug body, It is used for checking whether or not the power is on. A square piece 57 and a connecting piece 556 in which a convex circular portion 561 is integrally formed are arranged on the bottom surface of the housing chamber 551, and the square piece 57 and the connecting piece 556 are selectively connected via a guide plate 66. . The guide plate 66 has both wings, and the upper and lower concave portions at the center are fitted and supported by the plug main body, and have a seesaw shape swinging in both directions. The switch 6 has a middle hole 61 in the center, and an elastic means 612 is provided in the hole, and a telescopic shaft 62 biased by the elastic means 612 is provided at the end, and the telescopic shaft 62 is provided in the accommodation chamber 551.
