Terminal blocks are wire-to-board connectors that generally come in screwless style. This type of connector is used for connections between two points which need to be electrically isolated while joining several wires together. With a wide variety of sizes and styles, they can accommodate a wide range of cable diameters. Applications for terminal blocks span many markets from industrial equipment to consumer electronics, data/networking, aerospace, and military/defense.

The most common type of terminal block is the basic screwless blocker which can be easily snapped together without tools. Screwless terminal blocks feature a two piece design with a male and female piece that fit together to form the connection. This type of terminal block is generally preferred because it is fast and simple to use and can prevent potential terminal damage and wire misconnection associated with traditional screw type terminal blocks. Other popular styles include spring clamp terminal blocks which can be useful in high shock and vibration environments and also feature a relatively fast connection time. Other styles available are cage clamp, PCB, and telecom.

The physical shape or geometry of the terminal block is important in that it ultimately determines the maximum amount of wires that will physically fit in the block and how easy it is to wire them. Geometries can range from a standard flat rectangular shape to a more complex lever configuration. The most common style to consider is the “front and side access” terminal blocks which features a terminal housing configured with two sides and a front access busbar. This type of terminal block allows for easy routing of incoming and outgoing conductors into the busbar. Types of wipers integrated into the terminal block are made from a range of materials based on the application.

The working principle of terminal blocks is based on the concepts of variety of electrical connections. The wire(s) is then inserted into input slots of the terminal block at one end which are then held together with the help of other end pieces and tightened with the help of screws, nuts or any other type of tightening device. Thereafter electric current can be passed from one end to the other. The advantage of this type of connection is that it provides quick, easy, and reliable connections with minimal wiring complexity and ease of use.

Application-specific designed terminal block products are commonly found in the market. For example, there are terminal blocks designed for specialty applications such as power boards, solar panels, HVAC controllers, and even underwater submersible enclosures. The materials used for these designs range from high temperature thermoplastics, such as polyamide, polyphenylene oxide, which can withstand temperature up to 110°C, to Halogen Free and Flame Retardant thermoplastics that can withstand temperatures up to 180°C.

Overall, terminal blocks are an essential component to have in virtually any electronic system design, and as technology advances, newer designs continue to hit the market, allowing for faster, more reliable connections in an ever-evolving landscape of applications. With improved features, such as spring clamp locking mechanisms, and compliance with various certifications, terminal blocks are becoming even more popular and feature rich.
