Terminal Blocks, often referred to as a “wire to board” connector, is an essential part of many electrical systems, serving to link two points of electrical conduction. As its name implies, the blocks of this connector type are designed to be the endpoints in a wiring circuit, providing reliable contact points for power or signal wiring. The use of terminal blocks may vary from connecting external or internal devices to commercial, industrial, or consumer electrical wiring systems.
Common Applications and Usage
Terminal blocks are used universally in most electrical wiring projects, available in a range of sizes, configurations, and pin counts. Common applications for terminal blocks include commercial, industrial, and consumer applications which may require rigid, space-saving wiring with reliable, secure contact points. These include electronic control systems, household appliances, solar energy system components, audio/visual components, and more.
Types of Terminal Blocks
Terminal blocks come in a wide range of types, suited for a variety of applications. Each type has its own specific features, intended for different specific purposes. It is important for equipment designers to understand each type before selecting a terminal block for their application or wiring configuration.
Standard Pin Pluggable
Standard pin pluggable terminal blocks are designed for use with rigid and stranded wire. The standard pin pluggable type has several different contact configurations, including straight, multi-level, PCB mount, cassette mount, and more. They are available in 3-24mm2, with 0.08-16mm2 and 12-32A maximum current ratings.
PCB Terminal Blocks
PCB terminal blocks are typically designed to mount onto printed circuit boards, offering quick and easy connection with many types of rigid and stranded wire. They are available in a range of pin counts and sizes, such as 5-12A/ 9-12.5A/ 8-16A/12-15A/13-17A/14-18A/18-22A/24-25A/205-25A.
Spring Terminal Blocks
The spring terminal block is designed for use in control systems and applications with medium current ratings. The connections are made with a single layer spring contact, with no soldering required. In addition, it features a dual insulation system and protection from mating pin contamination. The block is available in 2-16A.
Working Principle
The two conducting elements of a two-pin terminal block are the terminal plate and the connection plate. The connection plate is inserted into the terminal plate and makes electrical contact with the plate’s metal contacts. This contact is usually made by either soldering, screwing, or pressing, depending on the type of terminal block. The terminal plate is then connected to the other pins in the wiring circuit with a conductor such as a wire.
In order to ensure reliable connection between the two parts of the terminal block, a secure mating system is used in two-pin types. This typically works with the arm of the terminal plate being inserted into a slot in the connection plate. This ensures a reliable connection between the two parts and prevents any of the contacts from detaching during use.
In the case of multiple pin terminal blocks, a similar approach is used but with additional contact points. These additional contact points are usually insulated from each other so that they do not interfere with the operation of the circuit. The connection is also secured using a secure mating system and the connection is usually made using a conductive material such as a wire.
Conclusion
Terminal blocks, or “wire to board” connectors, are essential components in any electrical wiring project. These connectors come in a variety of configurations, sizes, and pin counts, making them suitable for a wide range of applications. The working principle of terminal blocks involve a metal contact plate and a secure mating system to ensure reliable connection between the parts of the circuit.
