Terminal Blocks - Wire to Board: the ER1901500000G Application Field and Working Principle

Terminal blocks, also known as terminal boards, are printed circuit boards used to connect a number of different types of electrical wires or cables. The critical function of a terminal block is to safely connect and secure wires together. The brand of terminal blocks sourced by our company, ER1901500000G, is a terminal block of type wire to board, which is a kind of mechanical connector that is used to connect wire to a printed circuit board. To better understand the nature of ER1901500000G, this article will in-depth discuss its application field and working principle.

ER1901500000G Application Field

The ER1901500000G terminal block is ideally suited for high density wire to board applications, like those found on PC boards. With its miniature design, it is utilized in such products as automotive car electronic systems, industrial control, electric power, and small consumer electronics. The maximum current rating of this terminal block is 4A and the designated wire size range is 28AWG to 18AWG.

Understanding the ER1901500000G Working Principle

The working principle of the ER1901500000G terminal block is rather simple and straightforward. It is designed with two interlocking parts so that it can be mounted on any PCB. The top part of the terminal block consists of two arms which close around the prepared connecting wires, securing the wires in place when closed. The bottom part of the terminal block has a contact post that is crimped onto the wire and then soldered onto the desired board. This ensures appropriate and reliable connections.

The ER1901500000G terminal block uses various locking mechanisms to ensure secure connections between the wires and board. These include mechanical locks, which can be tightened manually or by tool. There are also electrical connections, and the current ratings should be taken into consideration when selecting the appropriate terminal block. Some terminal blocks also feature adjustable pins that can be moved to better ensure a secure connection.

The ER1901500000G terminal block has a unique plating structure as well. Gold plating is applied on the contact posts as a means of enhancing the electrical connection. This increases the current carrying capacity of the connection and prevents corrosion which could cause unreliable connections over time. The gold plating also helps insulate the connections.

Final Thoughts

The ER1901500000G terminal block is an invaluable connector that helps to ensure reliable and secure connections for a wide variety of electrical applications. Its miniature design makes it particularly useful for tight or dense applications. It is also easy to install and maintain, maintaining a tight grip on the wires and providing a secure contact post for soldering to the PCB. The gold plating on the contact post helps to enhance the connection and ensure a reliable electrical connection over time. It is an important component of any electrical system and should be chosen carefully to ensure the appropriate current rating.
