Accordingly, various electric wires are provided inside the electric transport system, and the electric wires are mutually connected through the electric wire connection terminal.

However, since the conventional electric wire connection terminal merely has a function of fixing each electric wire to mutually connect the electric wires, if the insulation environment around the electric wire is changed due to immersion of the electric wire connection terminal or exposure to moisture or the like, Occasionally, a short-circuit current is generated or a current is leaked to the outside of the electric connection terminal.

In addition, if a breaker for the safety of a wire breaks down, there is an electric shock accident due to a leakage current, and there is a possibility of human accidents. In addition, a short circuit current is generated between the wires, do.

In order to solve such a problem, a separate waterproofing process or winding of an insulation tape is used for the connection portion, but the waterproofing process is incomplete, the operation is complicated, and the cost is high.

In addition, the embodiments described below do not unduly limit the contents of the present invention described in the claims, and the entire constitutions described in the embodiments of the present invention are not necessarily essential as means for solving the present invention. The components applied to one embodiment can be applied to other embodiments without special mention.

1 to 5 show a smart safety access device 100 according to a first embodiment of the present invention.

The smart safety connection device 100 may be an electric wire connection terminal that performs a function of electrically connecting an external power source (for example, a DC power source or a commercial power source) to various loads. In the first and second embodiments And the third and fourth embodiments are applicable to the case of AC wiring. However, the present invention is not limited to this, and the first embodiment and the second embodiment may be AC wiring.

The smart safe connection apparatus 100 according to an embodiment of the present invention includes a first conductive member 125, a second conductive member 135, and a third conductive member 125 disposed in the terminal housing 110 and the terminal housing 110, And may include a conductive member 140. The smart safety connection apparatus 100 electrically connects both ends of the separated first cable 120 and electrically connects both ends of the separated second cable 130 to each other, It is possible to prevent the leakage current leaking from the outside from leaking to the outside.

At this time, the smart safety connection device 100 blocks an electric field leaking from the connection portion of the first cable 120, thereby preventing the leakage current leaking from the connection portion from leaking to the outside. In particular, the smart safety connection device 100 can block an electric field leaked through water even when immersed in water, thereby preventing leakage of current through water during immersion.

The terminal housing 110 includes a first cover member 111 and a second cover member 112 for supporting at least a part of the first cable 120 and the second cable 130, ). The first conductive member 125 and the second conductive member 135 may connect the connection portions of the first cable 120 and the second cable 130 to each other.

The first conductive member 125 may be connected to both ends of the separated first cable 120 to electrically connect the separated first cable 120. The second conductive member 135 may be connected to both ends of the separated second cable 130 to electrically connect the separated second cable 130.

Coated uncovered exposed portions 121 and 123 of the first cable 120 and the first conductive member 125 can be supported between the first cover member 111 and the second cover member 112 . At this time, the uncovered coated exposed portions 121, 123 of the first cable 120 and the first conductive member 125 may be the first connecting portion.

Coated uncovered exposed portions 131 and 133 of the second cable 130 and the second conductive member 135 can be supported between the first cover member 111 and the second cover member 112 . At this time, the uncovered coated exposed portions 131 and 133 of the second cable 130 and the second conductive member 135 may be a second connecting portion.

At this time, an electric field may leak from the first connection part exposed between the first cover member 111 and the second cover member 112, thereby generating a leakage current. Particularly, when a fluid such as water permeates between the first cover member 111 and the second cover member 112 due to immersion or the like, an electric field may leak through the fluid permeated therebetween, Lt; / RTI >

In this case, the smart safety connection device 100 blocks an electric field leaking through the first connection portion by the second connection portion and the third conductive member 140, thereby blocking the leakage current through the first connection portion .

The first conductive member 125 may be disposed between the first cover member 111 and the second cover member 112 to electrically connect both ends of the separated first cable 120. The second conductive member 135 may be disposed between the first cover member 111 and the second cover member 112 to electrically connect both ends of the separated second cable 130.

The third conductive member 140 is disposed between the first cover member 111 and the second cover member 112 and the first conductive member 125 is disposed between the second conductive member 135 and the third conductive member 125. [ May be disposed between the member (140). At this time, at least a part of the third conductive member 140 is electrically connected to the second conductive member 135 so that an electric field leaking from the first conductive member 125 is leaked to the outside through the second conductive member 135, . Accordingly, in one side, the second connection part blocks the leakage current leaking from the first connection part, and on the other side, the third conductive member 140 can block the leakage current leaking from the first connection part.

The first cable 120 and the second cable 130 may be arranged to penetrate the terminal housing 110 and the second cable 130 may be spaced apart from the first cable 120 by a predetermined distance. The third conductive member 140 is electrically connected to the second cable 130 through the connection member 145 inside the terminal housing 110 and the connection member 145 is electrically separated from the first cable 120 And may be arranged to intersect.

The first cable 120 may be provided to have a higher potential than the second cable 130. That is, when power is supplied to the electric wire connection terminal while the electric wire connection terminal connects the load and the external electric power source, the first cable 120 may be connected to have a higher electric potential than the second cable 130. For example, the second cable 130 may have a potential of 1V, and the first cable 120 may have a potential of 101V. Also, the first cable 120 may be a high electric potential cable, and the second cable 130 may be a low electric potential cable.

At this time, alternating current may flow through the first cable 120 and the second cable 130, the first cable 120 may be a normal power line, and the second cable 130 may be a neutral line. At this time, the neutral wire constitutes an electric circuit together with the main power line to supply current to the load. At this time, the neutral line constitutes an electric circuit as a part of the electric circuit, and it is possible to maintain the state in which the constant current flows, that is, the energized state. Accordingly, it is possible to block the electric field leaking from the phase line through the neutral line, thereby effectively blocking the leakage current from the phase line.

Also, the term "cable" can be used to refer to a plywood used for sending electric power or electric signals. The cable may comprise a conductive member (e.g., a metal wire of copper, aluminum, etc.) and an insulator (e.g., a covering portion formed of an insulating material).

The first cable 120 may have a potential higher than that of the second cable 130. In this case, the first conductive member 125 can connect a cable having a potential higher than that of the second conductive member 135.

The first conductive member 125 can electrically connect the first conductive core 121 and 123 of the first cable 120 having a high potential when the cable is connected by the smart safe connection apparatus 100. In addition, the second conductive member 135 can electrically connect the second conductive core 131, 133 of the second cable 130 having a low electric potential when the cable is connected by the smart safety connection device 100. At this time, a part of the first conductive cores 121 and 123 may be coated and exposed portions of the first cable 120. A part of the second conductive core 131 or 133 may be a covering exposed portion of the second cable 130. [

The smart safe connection apparatus 100 includes a first cover member 111 and a second cover member 111 which at least partly face each other and support the first cable 120 and the second cable 130 separated therebetween, (112); A first conductive member 125 disposed on the inner surface of the second cover member 112 and electrically connecting both ends of the separated first cable 120; A second conductive member 135 disposed on the inner surface of the second cover member 112 and electrically connecting both ends of the separated second cable 130; The first conductive member 125 and the second conductive member 135 are disposed on the inner surface of the first cover member 112 and the second cover member 112 and have both ends electrically connected to the second conductive member 135, 3 conductive member 140 as shown in FIG.

The smart safe connection apparatus 100 includes a first cover member 111 and a second cover member 112 separated from each other by at least a part of the first cover member 111 and the second cover member 112, So that the cables can be connected and connected by a simple operation. To this end, the smart safe connection device 100 includes conductive members 125, 125 for electrically connecting the conductive core of each of at least one pair of cables separated on at least one side of the pair of cover members 111, 112, 135, and 140 may be disposed.

In this case, the smart safe connection apparatus 100 is configured such that at least a part of the conductive core coated with the insulator between the pair of cover members 111 and 112 is exposed to the cable between the pair of cover members 111 and 112 The cable can be simply connected and connected by fixing the pair of cover members 111,

Accordingly, the smart safety connection device 100 can securely connect both ends of the interconnected cables by a simple operation, thereby improving workability of the cable connection operation.

The first conductive member 125, the second conductive member 135, and the third conductive member 140 may extend in at least one direction. For example, as shown in the drawing, the first conductive member 125, the second conductive member 135, and the third conductive member 140 may be spaced apart from each other by a predetermined distance and extend in the longitudinal direction, respectively. In this case, the first conductive member 125, the second conductive member 135, and the third conductive member 140 may extend substantially in parallel and be separated from each other.

The first connection portion may be disposed between the second connection portion and the third conductive member 140. In this case, an electric field leaking through the first connection portion is blocked by the second connection portion and the third conductive member 140, and the leakage current leaked through the first connection portion by the second connection portion and the third conductive member 140 .

The principle and effect of the second connecting portion and the third conductive member 140 blocking the leakage current leaking through the first connecting portion are shown in Figs.

Referring to FIG. 16, the first connection part 120a may be disposed between the second connection part 130a and the third conductive member 140 in parallel with each other.

The first connection part 120a has a potential of Vo [V] and the second connection part 130a and the third conductive member 140 have a potential of 0 [V], as shown in the figure. In this case, the potential distribution V (y, z) can be a function of y and z. The Laplace's equation can be expressed by the following equation (1). Further, the boundary condition can be expressed by the following equation (2).

At this time, the potential distribution V (y, z) is Obtaining a solution of Laplace's equation of equation (1) using the boundary condition of equation (2) is as shown in Equation 3, the electric field vector E is the potential distribution V (y, z) (4) through the slope.

Further, the current I can be expressed by Equation (5) by the resistivity ( rho ) of the electric field E and the surrounding material.

Therefore, by blocking the electric field ( E ) flowing out of the first connection part by the second connection part and the third conductive member, the smart safety connection device can cut off the leakage current leaking from the first connection part.

In addition, when the first connection portion is disposed between the second connection portion and the third conductive member in parallel to each other, the electric field E flowing out from the first connection portion is referred to as a second connection portion and the third connection portion By blocking the conductive connection member with the conductive member, the smart safety connection device can block the leakage current leaking from the first connection portion.

The length of the second connection portion and the length of the third conductive member 140 of the second cable 130 connected by the second conductive member 135 may be substantially the same. In this case, the end of the second connection portion and the end of the third conductive member 140 may be connected. For this purpose, a separate connecting member 145 may connect the end of the second connection portion and the end of the third conductive member 140. At this time, the connecting member 145 may be connected to a portion, for example, a center portion of the second connecting portion and the third conductive member 140, respectively.

The smart safety connection apparatus 100 may include a connection member 145 to prevent an electric field exiting from the first connection unit from leaking through the connection member 145 to the outside. The connecting member 145 extends from the third conductive member 140 to the coated exposed portion of the second conductive member 135 or the second cable 130 and extends across the covering portion of the first cable 120, The member 140 and the second conductive member 135 or the second cable 130 can be electrically connected to each other.

17 and 18 show the distribution of the electric field strength and the electric field vector analyzed through the electric field numerical analysis program in the case where the neutral wire and the normal power wire are arranged in parallel at the same size in the smart safety connection device according to the present invention.

Referring to the drawing, even in the case where the neutral line and the normal power line are arranged in parallel with each other in the same size in the smart safety connection device, the vicinity of the first connection part 120a, the second connection part 130a, and the third conductive member 140a The electric field is significantly reduced. Accordingly, by arranging the neutral line and the phase power line in parallel in the smart safety connection device, the leakage current can be reduced.

As another example, the length of the second conductive member 135 and the third conductive member 140 may be longer than the length of the first conductive member 125. The exposed portion of the second cable 130 connected by the second conductive member 135 and the length of the second connection portion 130b and the length of the third conductive member 140 are shorter than the length of the first conductive member 125 The length of the exposed portion of the first cable 120, that is, the length of the first connection portion 120b. Therefore, the leakage of the leakage current to the outside can be blocked by blocking the electric field flowing out from the first connection part 120a by the second connection part 130b and the third conductive member 140. [

19 and 20 show the distribution of the electric field strength and the electric field vector, which are analyzed through the electric field numerical analysis program when the neutral line is arranged in parallel with the length of the normal line in the smart safety connection device according to the present invention.

Referring to the drawing, in a smart safety connection device, when the neutral line is arranged longer than the normal line, the electric field exiting from the first connection portion 120b is divided by the second connection portion 130b and the third conductive member 140b, There is almost no electric field distribution outside the region. Therefore, by arranging the neutral line in the smart safety connection device so as to be longer than the phase line, it is possible to reduce leakage current leaking to the outside.

An upper central region 421b and a lower central region 422b and a first connection portion 120b and a third conductive member 140b are provided outside the region defined by the second connection portion 130b and the third conductive member 140b, The electric field distribution is weak in the left region 411b and the right region 412b outside the region formed by connecting the respective end portions. Therefore, the second connection part 130b and the third conductive member 140 block the electric field exiting from the first connection part 120a in the smart safety connection device, thereby preventing the leakage current from leaking to the outside.

19 and 20, the smart safety connection apparatus 100 includes an upper central region 421b, a lower central region 422b, a left region 411b, and a right side region 411b. The distribution of the electric field in the left side region 412a and the right side region 412b of the smart safety connection device according to the embodiment shown in Figs. 17 and 18 is smaller than the distribution of the upper central region 421a and the lower central region 422a, 412a, the distribution of the electric field is remarkably reduced.

An extension line of the electric field vector on the exposed portion of the first cable 120 connected by the first conductive member 125, that is, outside the upper or lower end of the first connection portion 120b, The first connection part 120b and the second connection part 120b are connected to the second exposed part of the second cable 130 connected by the member 135 or the second connection part 130b and / 130b and the third conductive member 140 can be made in length and / or arrangement.

In this case, the lengths of the second connection portion 130b and the third conductive member 140 are longer than the extension line of the electric field vector at the upper or lower end of the first connection portion 120b so that the first connection portion 120b It is possible to effectively block the electric field that is leaked through. Therefore, the leakage of the leakage current to the outside can be blocked by blocking the electric field flowing out from the first connection part 120a by the second connection part 130b and the third conductive member 140. [

The first conductive member 125 may be disposed on the inner surface of the second cover member 112 to electrically connect both ends of the separated first cable 120. The second conductive member 135 may be disposed on the inner surface of the second cover member 112 to electrically connect both ends of the separated second cable 130. The third conductive member 140 is disposed on the inner surface of the second cover member 112 so that both ends are electrically connected to the second conductive member 135 and the second conductive member 135, (Not shown).

To this end, the smart safe connection device 100 'may include a first shielding member 141 and a second shielding member 142.

Accordingly, the capacitance measured by the first connection portion 120a, the second connection portion 120a, and / or the third conductive member 140 is changed. Therefore, by detecting the change in capacitance of the first connection portion 120a, the second connection portion 120a, and / or the third conductive member 140, it is possible to determine whether or not the smart safety connection device is flooded.

The immersion determination unit can determine whether the smart safety connection device is submerged from the capacitance or current detected by the immersion detection unit. At this time, the immersion determination unit can determine that the smart safety connection device is immersed when the change in the measured capacitance or current value is equal to or greater than the set reference value. On the other hand, when the change in the measured capacitance or current value exceeds the set reference value for the set time, in consideration of the case where the change of the capacitance or the current value becomes large for other reasons such as noise, Can be judged to have been flooded.

At this time, if the electrostatic capacitance change pattern is set to the set electrostatic transition pattern, it can be determined that the electrostatic capacitance is immersed.

The immersion determination unit can communicate with the outside of the smart safety access device by wire or wirelessly via a separate data transmission / reception unit. The immersion determination unit may be connected to the data storage server and / or the analysis server through a separate data transmission / reception unit. The data storage server and / or the analysis server receives and analyzes the change pattern of the capacitance, and stores the capacitance change pattern or the current change pattern of the specific pattern as the change pattern or current change pattern of the capacitance at the time of flooding . At this time, the data storage server and / or the analysis server may receive the flood information, process it into a form specified by the user, and provide the flood situation of the corresponding area to the user. In this case, it is possible to more precisely and more adaptively detect whether or not flooding has occurred in the area.

When the smart safety connection device is judged to be flooded, the immersion control unit can notify that the immersion has been made to the outside, such as turning on the LED connected to the outside or activating the buzzer to output sound. In another embodiment, the housing includes a foaming portion made of an insulating material such as resin, and the flooding control portion activates the foaming portion so that the connecting portion of the cable in the space inside the housing is surrounded by the insulating material so as to be shielded from the outside. Therefore, the connection portions inside the housing can be physically completely blocked from the outside.
