The present invention relates to a multi-directional outlet having a short-circuit detection and disconnection function that is connected to the wiring to insert the plug in order to connect the cord used indoors in the indoor wiring of the electricity, more specifically, the connection of the plug in the multi-direction It is possible to easily connect “??” shaped plugs by minimizing the interference caused by the connection between the outlet and the plug, and to prevent the short-circuit accident by installing the device of the earth leakage detection and blocking function. In addition, the life of the outlet depends on the life of the connection terminal to maximize the life of the outlet, thereby improving the quality and reliability of the product to enable consumers to plant a good image.

As is well known, a receptacle is a wiring device having a function of easily connecting an electrical load connected to a plug to a power source.

In addition, an outlet type leakage breaker is an electrical outlet normally used for home use, and it detects leakage current, electric shock, and short circuit accidents and cuts off the circuit to prevent safety accidents.

The current leakage circuit breaker (rated voltage 110 / 220V, rated load current 30A, rated sensitivity current 30mA) detects the difference between the current flowing into the load side and the current flowing out of the load to open the electrical circuit. to be. Such a circuit breaker is used in home distribution boards, industrial distribution boards, and distribution boards, and the home is used for electric lines of AC110-220V, and the industrial is used for AC220-460V. In case of general households, an earth leakage breaker with a rated sensitivity current of 30 mA is mainly installed, but when handling electrical appliances in a humid place such as a bathroom, kitchen, laundry room, the sensitivity current is higher than that of an earth leakage breaker. There is an outlet equipped with a ground fault interrupter with a small rated sensitivity current (15 [mA]).

As a safety device of the conventional outlet as described above is a situation in which a plastic safety device is attached to prevent electric shock that may occur when a child or the like puts a sharp conductor in the pole of the outlet.

However, when the above-mentioned safety device is used for a long time, there is a problem in that the function is deteriorated. In addition, the outlet may be short-circuited when used in a humid place such as a bathroom, kitchen, utility room, or the like. There was a problem that there is no protection of electric shock that can occur when plugged in.

In addition, since the outlet according to the prior art has a structure having two connection terminals and two connection holes in one plug, its shape is '??' When a plug bent into a shape is inserted, it is difficult to couple a plurality of plugs to an outlet in the same direction.

In addition, it detects leakage current, electric shock and short-circuit accident and cuts off the electric current to prevent safety accident.

Referring to the technical effects of the present invention in more detail as follows.

That is, the present invention compensates for the disadvantages of existing outlets, and has four connection terminals 13 and four connection holes 12 in one connection port 11 for connecting a load. When two pairs of connecting terminals 13 are formed in one connector 11, when the pair of connecting terminals 13 is damaged, the plug 1 can be inserted into another connecting terminal 13 and used. As a result, it is possible to reduce the heat generation at the extension of the service life of the outlet and the contact area, thereby obtaining the effect of preventing fire.

In addition, as described above, the connection direction of the plug 1 is multidirectional, that is, four-way connection is possible. In this case, the interference caused by the connection of the outlet and the plug 1 is minimized. (1) and the like can be easily connected.

The present invention also has the effect of reducing the contact resistance of the plug (1) pin and the socket cutout due to the increase in contact area and contact pressure by providing the connection terminal 13 in a three-sided connection type.

In addition, the test button 16 applied to the present invention is to check whether the circuit for detecting a short circuit and trip is operating normally. In particular, when the test button 16 is pressed, the test switch is turned "on" so that the bypass current through R4. From the point of view of ZCT, the main contact is blocked because the difference between the current flowing from the load side and the current flowing from the load side occurs.

The reset button 15 is for closing the circuit when the circuit is open due to a short circuit / trip test. When the button is pressed, the main contact is turned on.

In addition, the earth leakage breaker 40 of the earth leakage detection and blocking function of the present invention, when a short circuit occurs in the load side as shown in Figs. 1 and 2, the difference between the current flowing into the load side through the ZCT and the current flowing out of the load side occurs, The difference is detected by the ZCT and sent to the IC for leakage detection and processing. Where R3 and C5 are applied to adjust the detection sensitivity. When the detected leakage current value exceeds the set value, a trip signal is generated, and this trip signal is applied to Q1. When Q1 is conducted, a trip current flows through the solenoid which is a trip coil, and a magnetic force is generated, and magnetic force is applied to a slurry inside the solenoid. This opens the main contact, which is mechanically connected to the plunger.

In addition, the present invention is provided with a ground terminal 18, as shown in Figure 8, when the electromagnetic wave generated in the electrical appliances connected to the outlet or short-circuit occurs so that it can be quickly flowed to the ground to ensure the safety of the user.

 As described in detail above, the present invention enables the connection of the plug in various directions, thereby minimizing interference due to the connection of the outlet and the plug, so that the plug can be easily connected to the “??” shaped plug and the like.
