Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a terminal stand intergrated with a monitor light,

The present invention relates to a cable connection terminal box integrated with a backlight monitoring device, and more particularly, to a backlight monitoring device integrated cable connection terminal box which is embedded in a lamp of a streetlight, And more particularly, to a lane monitor integrated cable connection terminal box which prevents frequent breakdowns through improved durability and function maintenance, and makes it easier to maintain street lights and power supply devices.

As shown in FIG. 1, the conventional street lamps are installed at predetermined intervals on the road or at the edge of the road, and the power cable c is installed in each street lamp 10 through the underground, have.

That is, in the conventional street light 10, the power cable c branched from the predetermined distribution box 15 is led to the inside of the lower end of the lamp 11, After the sheath was peeled off and connected to the supply device 13, the power cable was connected by a method of insulating the connection portion with an insulating tape or the like.

Particularly, various electric devices such as a ballast and an earth leakage breaker installed in the structure of the electric power supply device are installed together inside the lower end of the case, and the electric power cable (c) In order to connect the input side power cable, the load side power cable, and the connection cable for power supply in a four-wire type two-wire system so that the power is supplied in a split manner, a high- It is simply wrapped with insulating tape and insulated.

Therefore, the power cable (c) wiring method installed inside the case 11 of the conventional street light 10 is inconvenient to perform work in a narrow street, resulting in poor workability, There were many troubles in repairing and repairing.

In addition, when the lower part of the street lamp is partially clogged by heavy rain during the rainy season or when the rain cover is wetted by moisture and moisture, the insulation tape covering the wiring part of the power cable is peeled off, And a number of problems have arisen.

In order to solve the disadvantages and disadvantages of the conventional power cable connection structure and its installation structure, a power cable connection terminal block for facilitating the connection of the power cable is inserted into the lower end of the power cable, Simplifying the construction of the power cable inside the louver while facilitating the wiring work.

Therefore, there is an advantage in that such a connection terminal block is installed in the inside of the case, thereby reducing the occurrence of troubles or interruptions in the power supply due to moisture or moisture impregnated inside the case.

However, there is a problem that the connection operation of the power cable connected to the ballast, the earth leakage breaker and the lamp side is performed separately from the connection terminal block at the connection terminal block, and the connection method of such connection portion is also made of the conventional simple insulation tape connection method, There is still a disadvantage in that it can not solve the problems and inconveniences of the related art.

In addition, in recent years, artificial intelligence system has been applied to remotely manage a large number of street lights installed on the edges of roads and footpaths, so that it is possible to grasp leakage detection function, fault indication and grasp function, Functions and the like are installed in a conventional case.

Therefore, in order to perform various functions, in addition to the connection terminal block, a plurality of components are additionally installed in the inside of the case, so that the circuit between the connection terminal and the ballast is short-circuited, The conventional method in which the insulation is repeated is repeated as it is, so that the conventional problems are reproduced in spite of improvement of the connection method of the drawn power cable which has been solved by the installation of the connection terminal block.
