Description

Non-contact Power Supply Display Terminal Block

The present invention relates to a non-contact energization display terminal block, and more particularly, to a low-voltage board, a motor control panel, a distribution board and a switchboard, etc. (hereinafter collectively referred to as a 'switchboard'). It relates to a non-contact energization display terminal block configured to be confirmed.

In general, various types of terminal blocks are installed inside a switchboard to distribute and supply power supplied from the outside to a plurality of electric devices.

Many wires are connected to such a terminal block, and therefore, when working for maintenance, etc., the operator first needs to check whether the power is supplied to the wires connected to the terminal block in a live wire state or in a diagonal wire state in which the power supply is cut off. have.

Accordingly, conventionally, an operator carries and uses a detection device with a built-in battery to check whether the power source is live or dead. In general, when one end of the detection device is brought into contact with an electrode of each wire, the LED provided in the detection device is configured so that it lights up or a buzzer sounds depending on whether it is live or oblique.

However, since the detection device as described above requires an operator to check a large number of wires one by one to detect whether a live wire is present, it takes a lot of time to check whether a live wire or a dead wire is present. In the process of making contact, there is a risk of safety accidents, so a lot of caution is required when using.

Therefore, in recent years, various technologies for easily detecting whether a terminal block is live or not have been developed. As a prior art for this purpose, an indicator device for a terminal block of Korean Patent Publication No. 1744511 (hereinafter referred to as 'patent document') is an example. can be heard

The indicator device disclosed in the above patent document is made of an electrical non-conductor and includes a case having a block-shaped gantry part protruding from one end of the upper surface of the body to the other end in a bridge shape, and a connection terminal part of the terminal block, respectively. A plurality of connector terminal pieces are coupled to one side of the gantry unit so as to be energized, and one end of each of which is formed to protrude from one side wall of the gantry unit to the outside in the form of a plate so as to be slidably coupled to the plurality of connection terminal units, and a connector terminal; A plurality of power supply terminals are coupled to the other side of the gantry opposite to the one, one end is connected to the connector terminal piece, and the other end is connected to an external cable to supply power supplied through the connector terminal piece to the cable. A plurality of pieces are arranged on the upper surface of the gantry portion along the longitudinal direction of the piece and the gantry portion, and are connected to individually energize the plurality of connector terminal pieces. It is configured to include a lighting lamp that is turned on.

However, the indicator device disclosed in the above patent document may be indirectly affected by the induced current between the other terminals installed adjacently, such as displaying the terminal with a slanted line in a live state. And there is a problem in that it is difficult to accurately determine whether or not there is an oblique line.

Therefore, it is required to develop a non-contact type energization display terminal block with an improved structure so that it can accurately guide whether the terminal block has live or oblique lines, while reliably preventing the influence between terminals installed adjacently.
