At this time, the first insertion hole 111 is formed smaller than the outer diameter of the rotating body 2 to be described later so that the rotating body 2 does not fall upward after the rotating body 2 is installed inside the main body 1.

The lower housing 12 is formed so that the planar shape corresponds to the upper housing 11, and four second insertion holes 121 are formed at each end of the cross, respectively, which will be described later on the inner bottom of the second insertion hole 121. Two terminal insertion portions 122 into which two connection terminals 13 are fitted are formed to face each other. In addition, the lower housing 12 has an inner diameter extended to the outside so that the upper end of the second insertion hole 121 may be inserted and rotated to be described later, and the lower housing 12 may be described later on the center bottom of the lower housing 12. The fixing piece 123a and the guide 123b are protruded so that the switch 3 is fitted into and fixed, and the screw 3 is screwed with the upper housing 11.

The connecting terminal 13 is formed to correspond to the terminal inserting portion 122 in a cylindrical shape having one side approximately opened, and is fitted into and fixed to the terminal inserting portion 122, respectively. At this time, the connecting terminal 13 is formed of an elastic metal, and when the terminal of the plug is inserted, the side end of the connecting terminal 13 is bent outward so that the terminal of the plug is not scratched and damaged. That is, when the terminal of the plug is inserted into the side opening of the connecting terminal 13, the connecting terminal 13 opens and the terminal of the plug is inserted into the connecting terminal 13, and the connecting terminal 13 is closed. Firmly hold the terminals of the plug. As a result, even if an external impact is applied, the terminal of the plug of elastic connection terminal 13 is firmly held to prevent the plug from being separated from the connection terminal 13. At this time, the connection terminals 13 are connected in parallel with the switch 3 to be described later, the connected wires (not shown) will be apparent to those skilled in the art will be omitted in the present invention.

The ground terminal 14, each end is bent upward in a substantially cross shape, the upper surface of the bent end is formed convex, the bent end is protruded into the second insertion hole 121, respectively. In addition, the ground terminal 14 has an elastic force, and a region of the ground terminal 14 is opened in a cross shape so as to fit inside the lower housing 12 to be fixed. At this time, when the ground terminal 14 is installed in the lower housing 12, the fixing piece 123a and the guide 123b penetrate through the cross-shaped opening, and a part of the ground terminal 14 is a power line. It is connected to the ground line (not shown) included in the interior of (10). Here, the ground terminal 14 may be screwed to the lower housing 12 may be fixed to the lower housing 12.

The rotating body 2 is formed in a substantially cylindrical outer diameter larger than the inner diameter of the first insertion hole 111, and an insertion hole 21 having an upper surface is formed, and a terminal of a plug is formed at the bottom of the insertion hole 21. Two positions are opened at the bottom of the rotating body 2 such that the two connecting holes 22 to be inserted and the ground piece 24 protrude into the inside of the rotating body 2. The lower end of the rotating body 2 is provided with a protrusion 23 so that the ground piece 24 is fixed, and the ground piece 24 is fitted into the protrusion 23. At this time, the ground piece 24 is in the form of a letter "C" with an approximately open top, three through holes 241 are formed at the bottom and the through hole 241 in the center of the projection 23 of the rotor 2 It is fitted in one of the through-holes 241 disposed on both sides and is coupled to the rotating body (2). In addition, both ends of the ground piece 24 protrude into the rotor 2 through an opening formed at the bottom of the insertion hole 21. Here, the rotor 2 is fitted between the upper housing 11 and the lower housing 12, the lower end of the rotor 2 is fitted to the upper end of the second insertion hole 121, that is, the stepped portion, the rotor ( The upper end of 2) is caught by the second insertion hole 121 and rotates. Accordingly, when the rotating body 2 rotates, the ground piece 24 also rotates, and the convex portion of the ground terminal 14 is fitted into the remaining through hole 241 of the ground piece 24 so that the ground piece 24 is engaged. ) And the ground terminal 14 are connected.

Here, the plug 2 is provided in the lower portion of the connecting hole 22 to prevent foreign matter from entering the connecting hole 22 or to prevent the infant and child from inserting chopsticks or the like into the connecting hole 22. When fitted, a foreign matter blocking portion (not shown) may be provided in which the connection hole 22 is opened and the connection hole 22 is blocked when the plug is pulled out. As described above, the foreign matter blocking part is already known and publicly implemented as used in a general outlet, and a detailed description thereof will be omitted.

The switch 3 is fitted between the fixing piece 123a of the lower housing 12 and the guide 123b by a substantially rectangular parallelepiped, and is connected with the power supply line 10 provided in the side surface of the main body 1. In this case, the power line 10 includes a power supply line (not shown) and a ground line (not shown).

The connection check unit 4 includes a rotary blade 41 and a protrusion 42 to check whether the plug and the outlet are connected.

The rotary blade 41 is formed in a substantially fan shape around the rotator 2 but is integrally formed with the rotator 2. At this time, the rotary blade 41 is inclined to a predetermined degree in order to raise the protrusion 42 to be described later. Accordingly, when the rotor 2 rotates, the rotor blade 41 also rotates, and when the rotor 2 continues to rotate, the rotor blade 41 is caught by the stopper 114 formed in the upper housing 11. The angle of rotation of the rotor 2 is limited. In other words, if the rotation angle of the rotating body 2 is large, it may cause trouble to rotate the plug greatly. Therefore, the rotation angle of the rotating body 2 is limited through the rotary blade 41. Therefore, by restricting the rotation angle of the rotating body 2, the plug can be rotated at a predetermined angle and connected to the connection terminal 13.

Protrusions 42, the braille 421 that can be perceived by the visually impaired protrudes on the upper end, the lower end of the protruding portion 42 is formed inclined. The protrusion 42 is disposed between the upper housing 11 and the rotary blade 41, and the braille 421 is inserted into the braille hole 113. At this time, a coil spring 43 for inserting the braille 421 from the braille hole 113 between the protrusion 42 and the upper housing 11, that is, the protruding braille 421 may be installed. Accordingly, when the rotary blade 41 is rotated, the rotary blade 41 lifts the lower end of the protruding portion 42 so that the braille 421 protrudes through the braille hole 113, and again rotates the rotary blade 41 in the opposite direction. When rotated in the same manner, the braille 421 is inserted into the braille hole 113 by the coil spring 43, so that the plug connection state can be confirmed.

As for the return spring 5, roughly a tension spring is used, one end is fixed to the lower part of the rotary blade 41, and the other end is fixed to the stopper 114. As shown in FIG. At this time, the elastic force of the return spring 5 is set in a range in which the plug does not come off from the connection terminal 13. Accordingly, when the rotary blade 41 is rotated, the return spring 5 is extended, and when the plug is removed, the rotor 2 is restored to its original position by the return spring 5.

Hereinafter, with reference to the accompanying drawings will be described in detail the operating state of the rotary multi-outlet according to an embodiment of the present invention.

When the plug is inserted into the rotating body 2 while the switch 3 is turned on, the plug is rotated to the left, and the terminal of the plug is fitted into the connecting terminal 13.

In addition, when the rotating body 2 rotates, the ground piece 24 is also rotated together so that the hole of the ground piece 24 is slightly inserted into the protruding portion of the ground terminal 14 so that the ground piece 24 and the ground terminal 14 are rotated. ) Is connected. At this time, since the ground terminal 14 has an elastic force and the ground terminal 14 pushes the ground piece 24, the ground piece 24 and the ground terminal 14 remain connected without falling.

In addition, the rotary blade 41 rotates together with the rotor 2, the rotary blade 41 raises the protrusion 42, and as the protrusion 42 rises, the braille 421 passes through the braille hole 113. It protrudes to the upper surface of the main body 1. That is, the protruding Braille 421 can be confirmed that the plug is connected to the outlet, as well as the general public.

When the plug is rotated to the right to separate the plug from the outlet, the rotor 2 rotates with the plug, and the terminal of the plug comes out of the connecting terminal 13, and when the user pulls the plug, the plug is disconnected from the outlet. At this time, the terminal of the plug may be pulled out to remove the plug while the terminal is inserted into the connecting terminal 13, but the terminal of the plug is tightly held by the connecting terminal 13, which is larger than the force for rotating the plug when the plug is pulled out. You must pull by force. This is because the contact area between the terminal of the plug and the connection terminal 13 is wide and the contact area is wide, so that the friction force rises, making it difficult to remove the plug from the outlet. However, when the plug is rotated, only the force enough to overcome the elastic force of the connection terminal 13 can be easily removed from the outlet.

Here, when the rotating body 2 rotates to the right, the braille 421 of the protrusion 42 is inserted into the main body 1. At this time, the braille 421 may be inserted into the main body 1 by the weight of the protrusion 42, but the braille 421 may be inserted into the main body 1 by the coil spring 43 inserted into the braille 421. It can also be inserted inside.

On the other hand, the rotor 2 may be located in the middle without being completely rotated to the right, the braille 421 may protrude from the main body 1 to some extent. However, in the present invention, since the return spring 5 is installed between the rotary blade 41 and the stopper 114, the return spring 5 pulls the rotating body 2 so that the rotating body 2 closely adheres to the right side. By doing so, the rotor 2 is always kept in an initial state. Accordingly, when the outlet is not used, the braille 421 can be prevented from protruding from the main body 1.

In describing the present invention described above, even if the embodiment is different, the same reference numerals are used for the same configuration, and the description may be omitted as necessary.

Shall not be construed as being understood. Therefore, a person having ordinary knowledge in the technical field to which the present invention pertains may easily implement other forms of the present invention within the same scope as the above-described embodiments, or the present invention only by the description of the embodiments of the present invention.
