Description

Prevention of electric shock accident in apartment house distribution system

The present invention relates to an electric shock accident distribution system of an apartment house that prevents an electric shock accident in the electric field of an apartment house, and has a simple structure, but is fundamental to the electric shock accident that can be caused by mischief by chopsticks, etc. of curious children. It relates to a distribution system for preventing electric shock accidents in an apartment complex to be prevented.

In general, the wall outlet is installed in the wall to be able to supply power, as shown in Figure 1, is configured in a box shape and the case 10 is formed with a recess 11 to which the plug (1) is coupled to the front , It is provided inside the case 10 is made of an electrode 20 connected to a power source.

At this time, a pair of coupling holes 11a into which the legs 1a of the plug 1 are inserted is formed on the inner bottom surface of the recess 11, and the electrode 20 is located behind the coupling holes 11a. When the plug 1 is inserted into the concave portion 11 so as to be arranged, the leg 1a of the plug 1 passes through the coupling hole 11a and is in close contact with the electrode 20, so that the plug 1 is connected to an electronic product. Power can be applied to.

On the other hand, recently, in order to prevent electric shock accidents due to an outlet of an infant or child, an infant or a child or the like is chopsticks or the like in the coupling hole 11a by obtaining a rotating body 30 that covers the coupling hole 11a inside the outlet body. It is composed of a structure that can prevent electric shock by forcibly inserting the same conductor.

The rotating body 30 is configured to have a long rod shape to the left and right, so that the middle portion is rotatably coupled to the central portion of the rear surface of the concave portion 11 and elastically pressurized so that both ends cover the rear surface portion of the coupling hole 11a by a spring. , On both front surfaces of the rotating body 30, an inclined surface 30a is formed to correspond to the coupling hole 11a, and since the structure of the outlet is a generalized outlet structure that has already been performed, a detailed description thereof will be omitted. do.

Therefore, when the leg 1a of the pair of plugs 1 is inserted into the coupling hole 11a at the same time, the leading end of the leg 1a pushes the inclined surface 30a to rotate the rotating body 30 to rotate the coupling hole 11a. ) Is opened and then advanced to contact the electrode 20. In addition, when a child or an infant pushes a conductor such as chopsticks into only one of the coupling holes 11a, the rotating body 30 is not rotated to prevent chopsticks from contacting the electrode 20.

However, the rotating body 30 of such an outlet is intended to be rotated only when the inclined surfaces 30a on both sides are pushed at the same time, and is not rotated when only one inclined surface 30a is pushed using chopsticks. When the chopsticks are stirred after the chopsticks are inserted only into the coupling hole 11a, the coupling hole 11a is opened as the rotating body 30 is rotated, and the chopsticks contact the electrode 20 to cause electric shock. , Since the rotating body 30 is made of a synthetic resin material which is a non-conductor, when the rotating body 30 is pushed with a strong force, the coupling hole 11a is opened while the end of the rotating body 30 is bent, and thus chopsticks, etc. When forcibly inserted into the coupling hole 11a, there was a problem in that it was difficult to prevent an electric shock accident.

Accordingly, it is provided inside the case as a complement to the consort structure, the sensing means for detecting rotation or deformation of the rotating body; An operation switch provided on the outer surface of the case; A memory for storing voice data input through a microphone is provided, and is connected to a sensing means and an operation switch, so that an electronic relay is turned on only when the operation switch is pressed so that power is applied to the electrode, and when the operation switch is not pressed A control unit for reproducing voice data stored in the memory and outputting it through a speaker when it is sensed that the rotating body is rotated or deformed by the sensing means; An electronic relay provided on an intermediate portion of a power line connecting the electrodes to a power source and turned on and off by a control unit; An outlet composed of a microphone and a speaker connected to a unit (see Fig. 1B) was developed, but this also has a complicated structure and a problem in preventing electric shock completely, which is a fundamental distribution system to prevent electric shock in the play of curious children. The development of technology is very good.

The other electrode is connected via two auxiliary terminals 121a and 121b formed in the intermediate body 120.

The upper body 130 is formed with a concave portion 131 to which the plug 200 is coupled on the front surface, and a pair of legs 210 of the plug 200 is inserted into the inner bottom surface of the concave portion 131. The leg coupling hole 132 is formed.

When the plug 200 is inserted into the outlet 100, the auxiliary terminals 121a and 121b are energized in series by the auxiliary connecting portions 213 formed on both legs 210 of the plug 200, so that ± One of the electrodes is electrically connected to one of the main terminals 111a and 111b (11b) by electrical connection between the auxiliary terminals 121a and 121b of the outlet 100 and the auxiliary connection portion 213 of the plug 200. The other of the ± electrodes of the power supply is electrically directly connected to the other of the main terminals 111a and 111b (111a).

Looking at the working relationship between the outlet 100 and the plug 200,

When the plug 200 is inserted into the outlet 100, + electrode among the + electrodes of the power source is directly connected to the main terminal 111a, and-electrode is the auxiliary terminal 121a among the two auxiliary terminals 121a and 121b. And the other auxiliary terminal (121b) is electrically connected to the other main terminal (111b), thereby inserting the plug into the outlet, each auxiliary terminal by the auxiliary connection 213 of the plug (200) ( 121a' and 121b" and 121b' and 121b") are electrically connected, and between the two auxiliary terminals 121a and 121b are electrically connected by a conductor 121c so that the other electrode is the other main terminal 111b. ).

As a result, power is supplied to the electronic products through the power connection unit 211 of the leg 210 of the plug 200 in contact with the outlet main terminals 111a and 111b.

On the other hand, when the child is not inserting the plug into the outlet, that is, the child is not using the outlet, the child is inserting chopsticks into the leg coupling hole 132 of the outlet 100, the auxiliary formed in the intermediate body 120 of the outlet 100 Since the main terminals (111a, 111b) formed on the lower body 110 are blocked by being blocked by the terminals 121a, 121b, the chopsticks are not directly connected to the ± electrode of the power source, so that no electric shock is generated.

Here, since the auxiliary terminals 121a and 121b are inserted by an adult when the plug is inserted, the leg 210 of the plug can be pushed through the auxiliary terminals 121a and 121b of the outlet to the main terminals (111a and 111b). When the child inserts the chopsticks into the outlet 100 and the leg coupling hole 132 as a joke, the chopsticks penetrate the auxiliary terminals 121a, 121b and cannot easily reach the main terminals (111a, 111b). to be.
