Description

Distribution board outlet {Outlet for distribution switchboard}

The present invention relates to a distribution panel outlet, and relates to a distribution panel outlet to be installed on the outer side of the distribution panel for connecting and using various construction tools, electrical equipment, tools and the like in the field.

The distribution panel is provided as a means for safely distributing and supplying power to various electric equipments used in various construction sites and workplaces, and an input terminal for receiving power from an external source and a power supplied from the input terminal to each electric load. A circuit breaker, which is a safety device to cut off the current supply when the overload occurs in the process, is built in the distribution panel housing, and the circuit brake is connected to the main circuit brake connected to the input terminal side and to the various electric load sides, respectively. It has a conventional structure consisting of a circuit brake.

In this structure, the terminal or the circuit breakers are wired to each other, and are combined in a module form in a predetermined housing to form a distribution board.

These distribution boards are usually provided with an outlet on the side, and the front plug connection of the outlet is equipped with a cover to maintain safety in the rain.

Therefore, in the field, when each electric appliance is used by using an external outlet of the distribution board, work can be performed by connecting the plug of the electric appliance to the plug connection part of the outlet, and if an overcurrent phenomenon occurs due to an overload factor during the work, The installed overcurrent breaker can be operated to cut off the power, and after the cause of the overcurrent is removed, the overcurrent breaker can be restored and the power can be used through the outlet.

However, conventional distribution panel outlets have a number of disadvantages such as:

First, although it is equipped with a cover for rainy weather, it is still vulnerable to leakage due to rainwater seeping into the gap due to the protruding mounting of the outlet and the cover being exposed to the outside.

Second, in the case of the existing distribution panel outlet, there is a function to actively cope with an abnormality such as an overload or a short, but it is insufficient to cope with the problem that the short circuit occurs and can not be confirmed by the naked eye from the outside.

Third, when there is a need to connect and use several electric appliances in the field, it is installed by using a number of outlets by simply connecting them, so that they become bulky and occupy a lot of space and cause interference with peripheral components. The space utilization inside or around the distribution panel is poor.

Fourth, in the case of the existing distribution panel outlet, the assembly is complicated and there is a problem that the manufacturing process is inefficient.

Fifth, in the case of the existing distribution panel outlet, the current pass rate is also inefficient problem.
