Terminal Blocks - Headers, Plugs and Sockets includes many types of products that can provide electrical connections between several conductive parts. The 1986375-4 is one such product. It is a IEC Type 4.5mm Hard Barrier Terminal Block which can help to connect many different parts in a reliable and secure way. This article will provide an overview of the application field and working principle of the 1986375-4 Terminal Block.

Application Field

The 1986375-4 Terminal Block is typically used in industrial applications, particularly those related to 19-inch rackmount products. The Terminal Block helps to ensure reliable power distribution of 19-inch rackmounts to other products or mechanical components. It can also be used in other types of equipment, such as automatic control systems and computer systems, where reliable and secure power distribution is necessary.

The 1986375-4 Terminal Block is especially useful in situations where several bulky or difficult to connect cables are necessary. It can help to make a secure connection among several conductive elements, including busbar systems, automatic control systems, and computer systems. The Terminal Block also provides a safe voltage distribution which can prevent short circuits and other dangerous electrical situations.

Working Principle

The 1986375-4 Terminal Block works on the principle of a “hard barrier” connection. This is a type of connection where two conductive parts are joined together using screws and a forming tool. This type of connection ensures an airtight seal between the two parts, which helps to prevent the possibility of electrical interference from outside sources. In addition, the hard barrier connection offers good resistance against mechanical forces, which helps to make a reliable connection that is hard to break or damage.

In the case of the 1986375-4, the Terminal Block includes two parts - a male and a female block. The male block includes pins that fit the female block, and can be secured using two screws that also secure the forming tool. The male block can be connected to other electrical parts through these pins, while the female block serves as the ground. This allows the current to be distributed safely from the male to the female block.

The 1986375-4 Terminal Block also offers additional safety features that help to protect the equipment from electrical shocks and short circuits. It includes VDE0400 break-away screws, which serve as an additional safety feature by breaking away if too much strain occurs. Additionally, it includes a over-voltage protection system, which helps to prevent an overload by cutting off the power supply if the current is too high.

In conclusion, the 1986375-4 Terminal Block is a reliable and secure solution for 19-inch rackmounts and other demanding applications. It works on the principle of a hard barrier connection, and includes additional safety features such as break-away screws and over-voltage protection. This helps to make it a reliable solution for a variety of demanding applications.
