Looking at the rotary electrical connection device according to the present invention in more detail as follows.

Referring to FIG. 2, the rotatable electrical connection device 100 according to an exemplary embodiment of the present invention is coupled to one side of a pair of input pins 113 inserted into an AC power outlet and supplied with power, and the other side of the input pins. An input unit 110 including a body 111 having a plurality of first connection terminals 115a and b coupled to 113 and a plurality of second connection terminals 123a and b corresponding to the first connection terminals 115a and b; A connecting portion 120 including a connecting member 121 coupled to the terminal 115a, b and the second connecting terminal 123a, b by a coupling means 125 capable of free rotation, the first connecting terminal 115a, b and the second connecting terminal 123a, Each of the contact portion b is made up of a plurality of energizing portion 130 to be grounded to each other even when the connection of the rotation 120.

Here, the same reference numerals as in the above-described drawings indicate the same members having the same function.

First, the input unit 110 is composed of a body 111, an input pin 113, the first connection terminal 115a, b.

Here, the input pin 113 is composed of a pair to receive the power divided into (+), (-) pole. Typically, 220v has a round end and a round cross section, and 110v has a curved end and a rectangular cross section. This input pin 113 is connected to a connector inside the outlet. The input pin 113 connected as described above may receive electricity required for operation of the home appliance from the outside.

The input pin 113 is coupled to be partially inserted into the body 111.

On the other hand, the other side of the body 111 is coupled a plurality of first connection terminals 115a, b. Here, the connection position of the first connection terminal 115a, b should not change even if it rotates. That is, the first connection terminal 115a is coupled in the shape of a disc in the center to receive power divided into the (+) and (-) poles input to the input pin 113, and the first connection terminal 115a coupled to the center of the The first connection terminal 115b having a donut shape to the outside is coupled.

On the other hand, the connecting portion 120 is composed of a connecting body 121, the second connecting terminal 123a, b, the storage piece 127.

Here, the plurality of second connection terminals 123a and b are coupled to one side of the connecting body 121 in a disc shape, and the second connecting terminal 123a at the center of one side surface of the connecting body 121 is placed at the same position as the first connecting terminal 115a. To combine. In addition, the second connecting terminal 123b is coupled to the upper and lower portions of the second connecting terminal 123a to be positioned at the same position as the diameter of the first connecting terminal 115b.

On the other hand, a plurality of conductive parts 130 are provided in contact with the first connection terminal 115a, b and the second connection terminal 123a, b so as to ground each other even when the connection portion 120 rotates.

Here, the energizing unit 130 is formed in a spherical shape to minimize the contact surface of the energizing unit 130 in contact with the first connection terminal 115a, b and the second connection terminal 123a, b.

That is, since the conductive part 130 in contact with the first connection terminal 115a and b and the second connection terminal 123a and b is formed in a spherical shape, the free rotation is minimized by minimizing the contact surface of the energizing part 130 to be supplied with power while free rotating. Even if the power is constantly supplied, the rotation is smooth, and durability is improved.

As such, the first connection terminal 115 and the second connection terminal 123 are rotatable when the input unit 113 including the power supply input pin 113 and the first connection terminal 115 grounded and the connection unit 120 including the second connection terminal 123 are rotatably coupled. By providing a plurality of energizing parts 130 to be grounded to each other, free rotation is possible in more than 360 ° in both directions, so as to prevent the wire W from being twisted due to the use of home appliances. It is easy to store, and the electric wire W inside is not short-circuited.

On the other hand, the first connecting terminal 115a, b of the input unit 110 and the connecting unit 120 and the second connecting terminal 123a, b is provided with a coupling means 125 coupled to allow free rotation.

The engaging piece 125b of the upper part is formed.

As such, when the other side of the body 111 is pressed in the other direction of the connecting portion 120, the locking protrusion 125a is inserted into the locking step 125c while being deformed inward by riding the locking piece 125b. The fitted coupling portion 120 can be rotated in the left and right directions, it is possible to rotate more than 360 °.

At this time, the shape of the locking protrusion 125a can be freely deformed into a shape that is inclined outward or a hemispherical triangle shape. In addition, since the shape of the locking protrusion 125a is changed, the shape of the locking step 125c is also correspondingly modified.

That is, due to the coupling means 125 having a plurality of engaging protrusions 125a formed on the input unit 110 and an annular locking piece 125b having a locking step 125c formed on one side of the connecting unit 120, the connecting unit 120 coupled to the input unit 110 can be freely rotated. While making it easy to attach and detach, maintenance is improved.

In addition, as shown in FIG. 4, a plurality of rolling means 129 may be provided between the engaging protrusion 125a and the engaging piece 125b. Here, the rolling means 129 is embedded in a plurality of the inner edge of the engaging piece 125b in the same shape as the ball bearings and point contact with the outer surface of the engaging protrusion 125a to reduce the frictional force.

That is, when the connecting portion 120 rotates in the left and right directions, the frictional force is reduced due to the rolling means 129 to increase the rotational force.

On the other hand, when the conducting unit 130 is in contact with the first connection terminal 115a, b and the second connection terminal 123a, b, respectively, so that the ground of the conducting unit 130 does not change when the ground of the connection unit 120, the first connection terminal 115a A plurality of tubular accommodating pieces 127 surrounding each of b are combined.

At this time, the insertion hole 127a corresponding to the diameter of the energizing portion 130 penetrates through the center of the storage piece 127. In this way, by providing the storage piece 127 for storing the current-carrying unit 130, the position of the current-carrying unit 130 does not change when the plug is freely rotated due to the twisting of the wire W so that the power is constantly supplied without breaking the home appliance. Work is not cut off and work efficiency is increased.

In addition, even when the direction in which the wire W is drawn in and the second connection terminals 123a and b are formed vertically, the connector 121 may be easily plugged into an outlet having various directions of pin insertion holes.

In addition, as shown in Figure 4, by cutting a part of the first connection terminal 115b to provide a disconnection space 124 so that the power supply is cut off when the energization portion 130 is located in the disconnection space 124 by the rotation of the connection portion 120. .

That is, when the support line 140 formed on the outer periphery of the connecting portion 120 and the guide line 141 formed on the outer periphery of the input unit 110 coincide with each other, the energization unit 130 is positioned in the power cut space 124.

That is, when the power supply unit 130 is located in the disconnection space 124 by the rotation of the connection unit 120, the power supply is cut off while the input unit 110 and the connection unit 120 are disconnected, so that the power supplied to the plug is cut off without removing the plug from the outlet. It saves power and extends product life.

In some cases, as shown in FIG. 6, the body 111 of the input unit 110 may be transformed into a connecting body 121 of the connecting unit 120 to be used as a connection adapter for an electric wire instead of a plug.
