Terminal blocks, commonly referred to as ‘connectors’ or ‘electrical connectors’, are an integral part of any electronic device. They are designed to efficiently connect electrical signals between devices and systems. Terminal blocks are available in a wide variety of forms such as wire to board, fuse blocks, cord end, and more. This article outlines the common application fields and working principles of terminal blocks and examines the features and properties of the 1990818 type.
Terminal blocks come in a wide range of sizes, shapes, voltages, and current ratings, and are used in many different industries. They provide a secure connection and safe insulation over a wire, allowing efficient and secure electrical connections to be established between two circuit boards. Depending on the environment, terminal blocks can serve as long-term or short-term connections, or removable disconnect points for flexibility and maintenance. Examples of applications include electrical wiring, solar panels, automotive, industrial control, switchgear/breaker panel, power electronics, and more.
The 1990818 type terminal block is an intelligent wire-to-board connection solution for power and signal applications, and is rated for current and voltage. It is also UL listed, IEC 60320 rated, and CE marked. The design uses a two-piece molded construction with a “clip” portion and a “spring” portion. The clip portion provides firm contact pressure between the terminal block and the mating conductor, while the spring portion ensures that the connection is secure. In addition, the 1990818 terminal block also offers insulation displacement contact (IDC) technology for increased reliability. This terminal block also comes with a fixed or movable mounting plate for additional stability.
When connecting the 1990818 type terminal block, an insulation displacement connection (IDC) is made. The conductor is inserted into the IDC contact area at the end of the terminal block. The springs on either side of the IDC contact cause a slight outward compression, which prevents a short circuit due to metal fatigue. The gaskets, meanwhile, provide a seal that prevents water, dust, and other contaminants from engaging with the terminals. This terminal block also features a “floating cage” which ensures that the proper connection has been made, even in the presence of vibration or temperature changes.
In addition to its advantageous design and improved reliability, the 1990818 terminal block provides an easy and fast connection. It has a quick-connect feature that allows the terminal block to be connected and disconnected in seconds. This terminal block also offers a security system which prevents accidental disconnections. It has a unique locking system which limits the ability of the wire to be pulled out of the terminal block.
Terminal blocks are a reliable, easy, and safe way to establish electrical connections in larger or smaller circuits and systems. The 1990818 type terminal block is a wire-to-board connection solution that is designed for power and signal applications and is UL listed, IEC 60320 rated, and CE marked for safety and quality. It helps ensure a secure connection and safe insulation, and provides an easy and fast method of connecting signals between devices.
