BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings illustrate exemplary embodiments of the present invention and are provided to aid in the understanding of the present invention only. In the following description of the exemplary embodiments of the present invention, a detailed description of known general functions and / or configurations will be omitted.

The plug according to the present invention is used by being plugged into an outlet as known in the art, and supplies the electric power supplied from the outlet to the electric appliance. 1 to 3 show a plug according to a first embodiment of the present invention. 4 and 5 show a plug according to a second embodiment of the present invention.

1 to 3, a plug according to the present invention includes a body 10, two terminals 20, and a switch 30.

The body 10 is made of an insulating material, which can be configured as usual. The body 10 can be selected, for example, from a plastic material. According to one embodiment, the body 10 includes an upper housing 12 and a lower housing 14 coupled to the lower portion of the upper housing 12.

The two terminals 20 are electrically conductive and comprise, for example, an electrically conductive metallic material. The two terminals 20 are electrically connected to the electric wire W of the electrical product while being fixed to the body 10. Specifically, one side (right side in the figure) of each terminal 20 protrudes from the body 10 and is exposed to the outside, and the other side (left side in the drawing) is connected to a wire W As shown in Fig. At this time, as is well known, the electric wires W drawn out from the electrical product are two strands, and the electric wires W of these two strands are electrically connected to the two terminals 20, respectively. The electrical connection structure between each terminal 20 and the electric wire W can be configured as usual.

The switch 30 is provided on the body 10, and turns on / off the power supplied to the electric appliance. The switch 30 may have various structures as long as it can turn on / off the power. The switch 30 is, for example, a switching method which is mainly used in a general electrical connection structure, and may have a structure for turning on / off a power supply in a seesaw form.

According to a preferred embodiment of the present invention, the switch 30 may be configured as described below. The structure of the switch 30 described below is simple, but malfunctions can be prevented. For example, in the case of the seesaw-type switch 30 structure, a malfunction may occur due to the on / off state of the switch 30 due to a human step or an external force (collision) It is possible to prevent the malfunctioning and also the structure is simple. Hereinafter, the structure of the switch 30 according to the preferred embodiment of the present invention will be described.

First, the body 10 includes an upper housing 12 and a lower housing 14 as described above. At this time, the upper housing 12 is formed with a lever engaging portion 15 provided with a thread S thereon. The lever engaging portion 15 has a hollow cylindrical shape as illustrated in FIG. 2, which is formed to extend downward from the upper housing 12, and a thread S is formed on the inner circumference thereof have.

In addition, the lower housing 14 is formed with a wire fastening portion 16 and a terminal fastening portion 18. The coupling portions 16 and 18 protrude upward from the bottom portion 11 of the lower housing 14 and may have coupling holes 16a and 18a, respectively. Additionally, the lower housing 14 may be provided with a support portion 17 protruding upward from the bottom portion 11. At this time, the electric wire W is connected to a connecting member 32 which will be described later, and the terminal 20 and a grounding member 34, which will be described later, are connected in the terminal connecting portion 18. The support portion 17 supports the connection member 32 to be described later.

The switch 30 includes two connecting members 32 connected to the electric wire W of the electrical product, two grounding members 34 connected to the terminals 20, And a rotating lever 38 for pressing the pressing plate 36. The pressing plate 36 is provided with a pressing plate 36,

The two connecting members 32 are electrically conductive, and they are electrically connected to the two wires W drawn out from the electrical product, respectively. The connecting member 32 can be selected from a metallic material such as copper, iron and / or an alloy thereof, for example. At this time, one side (left side in the figure) of the connecting member 32 is connected to the electric wire W and the other side (right side in the figure) is energized or disconnected with the grounding member 34 by the operation of the rotating lever 38. Specifically, one side (left side in the drawing) of the connecting member 32 is electrically connected to the electric wire W at the electric wire fastening portion 16. More concretely, for example, a fastening hole 32a through which the first fastening member 41 is inserted is formed on one side of the connecting member 32. [ At this time, the first fastening hole 41 is connected to the electric wire W and is inserted into the fastening hole 32a and fastened to the fastening hole 16a of the electric wire fastening part 16. [

According to one embodiment, the connecting member 32 has a plate shape of a predetermined length, and a protrusion 32-2 is formed at the center, and the protrusion 32-2 is formed at one side And a connecting portion 32-1 that is energized with the grounding member 34 is provided on the other side (left side in the figure). At this time, the fastening portion 32-3 may be formed with the fastening hole 32a. In addition, the connection portion 32-1 may be supported by the support portion 17 of the lower housing 14.

The two grounding members 34 are electrically conductive, and they are each connected to two terminals 20. Further, the grounding member 34 has elasticity. The grounding member 34 is made of, for example, an electrically conductive metal having a predetermined elasticity. More specifically, for example, the grounding member 34 may be formed by plating a conductive metal such as copper on a resilient metallic material from stainless steel or carbon steel.

One side (the right side in the figure) of the grounding member 34 is electrically connected to the terminal 20 and the other side (left side in the drawing) is electrically connected to the connection member 32 by the operation of the rotation lever 38 It is cut off. Specifically, one side (the right side in the drawing) of the grounding member 34 is electrically connected to the terminal 20 at the terminal fastening portion 18. More specifically, for example, an insertion hole 34a through which the second fastening hole 42 is inserted is formed on one side of the grounding member 34. At this time, the second fastener 42 passes through the insertion hole 34a in the state of being connected to the terminal 20, and is fastened to the fastening hole 18a of the terminal fastening portion 18. [ In addition, the terminal 20 may have a structure in which a through hole 20a through which the second fastener 42 is inserted and penetrated is formed.

According to one embodiment, the grounding member 34 has a plate-shaped or strip-shaped grounding portion 34-1 of a predetermined length, and an extending portion 34-1 extending perpendicularly from the grounding portion 34-1. And an engaging portion 34-3 extending at right angles from the extending portion 34-2. At this time, the grounding part 34-1 is energized with the connection part 32-1 of the connecting member 32 when the pressing plate 36 is pressed by the operation of the rotation lever 38. [ The engaging portion 34-3 is coupled to the terminal engaging portion 18. The insertion hole 34a may be formed in the coupling portion 34-3.

In the present invention, the first fastening member 41 and the second fastening member 42 are not particularly limited as long as they can provide a fastening force, and the first fastening member 41 and the second fastening member 42 may be made of an electrically conductive metal material, for example. The first fastening member 41 and the second fastening member 42 may be selected from metal screws, bolts and / or rivets.

The pressure plate 36 is formed on the grounding member 34, which is insulating. The pressing plate 36 is in the shape of a plate selected from an insulating plastic material or the like and is mounted on the grounding portion 34-1 of the grounding member 34. [ This pressure plate 36 simultaneously presses the two grounding members 34 to energize the respective grounding members 34 and the connecting member 32.

The rotating lever 38 may be made of a plastic material and is rotatably coupled to a cylindrical lever engaging portion 15 formed in the upper housing 12 of the body 10. Specifically, a thread S is formed at the lower end of the rotary lever 38. Accordingly, the rotation lever 38 is rotated while being screwed to the lever engaging portion 15. By the rotation operation of the rotation lever 38, the grounding member 34 and the connecting member 32 are energized or disconnected. More specifically, when the rotary lever 38 is rotated in the clockwise direction, the rotary lever 38 is rotated downward by the screw rotation so as to press the pressure plate 36. By the urging force of the pressure plate 36, (34) is brought into close contact with the connecting member (32) to be energized. On the contrary, when the rotary lever 38 is rotated in the counterclockwise direction, the pressing force is released, and the grounding member 34 and the connecting member 32 are disconnected. In other words, when the pressing force is released, the grounding member 34 is restored by the elastic force, and accordingly, it is separated from the connecting member 32 and is cut off.

In the structure of the switch 30 described above, the power is turned on / off by the rotation operation of the rotation lever 38, which has a simple structure in comparison with the structure of the switch 30 in a general seesaw form. Further, on / off of the power source is realized by artificially rotating operation of the rotation lever 38, so that occurrence of malfunction is less than that of the seesaw type switch 30 structure. Specifically, as mentioned above, the structure of the switch 30 in the seesaw type can be easily turned on / off by a human step or by an external force (collision) around the switch. However, Since it is operated by the rotation operation, that is, it is turned on / off only when the person manually rotates by hand, malfunction can be prevented.

On the other hand, in general, most conventional plugs are manufactured to have waterproofness. That is, the connecting portion between the body 10 and the electric wire W and the connecting portion between the body 10 and the terminal 20 are designed to have a waterproof structure in order to prevent moisture infiltration. However, according to the present invention, the structure of the switch 30 as described above is installed in the body 10, so that moisture can be infiltrated. Specifically, moisture can be infiltrated around the rotation lever 38. [ The connection part between the electric wire W and the connecting member 32 and / or the connecting part between the terminal 20 and the grounding member 34 are oxidized to cause a ground fault, for example, , Durability may be reduced.

Thus, according to the embodiment of the present invention, it is preferable that at least the periphery of the rotation lever 38 is waterproof. In the present invention, the waterproof property is at least liquid impermeable (moisture barrier property), which may also mean gas impermeability (moisture barrier property). Figs. 4 and 5 show a cross-sectional view of the main part of the plug according to the second embodiment of the present invention.

4 and 5, waterproofing members 51 and 52 may be installed on the rotation lever 38 for waterproofing the structure of the switch 30 as described above. The waterproofing member 51 includes a first waterproofing member 51 provided at a substantially center of the rotation lever 38 and a second waterproofing member 52 provided at a substantially lower end of the rotation lever 38 . Further, a step 15a may be formed on the lever coupling portion 15 to which the rotation lever 38 is coupled.

4, when the pressing force is applied to the pressing plate 36 by the rotation of the rotating lever 38, that is, when the rotating lever 38 moves downward to press the pressing plate 36 (In the case of energization), the first waterproofing member 51 is tightly packed on the step 15a, and waterproofing is achieved. 5, when the pressing force is released from the pressing plate 36 by the rotation of the rotation lever 38, that is, when the rotation lever 38 is moved upward to release the pressing force The second waterproofing member 52 is tightly packed on the distal end 15b of the lever engaging portion 15 to provide waterproofness. Specifically, in the case of energization, the waterproofing is achieved by the close packing of the first waterproofing member 51 and the step 15a. In the case of the shorting, by the tight packing between the second waterproofing member 52 and the end 15b Waterproofing is achieved.

On the other hand, in the present invention, the first waterproofing member 51 and the second waterproofing member 52 are not particularly limited as long as they are capable of achieving waterproofness. The first waterproofing member 51 and the second waterproofing member 52 may be selected from elastic airtight materials such as, for example, silicone, rubber and / or polyurethane. The first waterproofing member 51 and the second waterproofing member 52 may have a disc shape having a through hole through which the rotation lever 38 can penetrate in the center. The first waterproofing member 51 and the second waterproofing member 52 may be fixed to the rotation lever 38 by an adhesive and / or a groove.
