Terminal blocks are electrically conducing fixtures that typically function to join together two or more wires in a circuit. They are used in a variety of formats, such as from single-pole to multi-pole options, and in both fixed and adjustable designs. Specialized terminal blocks are those that are specialized for particular application fields or for particular working principles. Application fields and working principles for specialized terminal blocks include hazardous locations, surface-mount terminal blocks, communications systems, wire-to-board connectors, and solar-panel systems.

Hazardous Locations

Hazardous location terminal blocks are those that are made specifically for industries that include potentially dangerous materials or which require particular safety measures. They are typically made with flameproof insulation, so that any potential spark cannot create a disruption. Some hazardous location terminal blocks also feature slots that are filled with sand or metal to provide further insulation. Flameproof terminal blocks are used in locations that may contain dust or gases, such as with coal mines and oil field production.

Surface-Mount Terminal Blocks

Surface-mount terminal blocks are those that are used in applications that require that the blocks themselves minimize size. They are typically used in circuit boards to provide low-voltage/current power. Surface-mount versions of terminal blocks are typically thinner, with most designs ranging from 6 to 8.2 mm. They are typically secured in place via two or more screws, but others may also use spring clips.

Communications Systems

Communication terminal blocks are those that are designed for data, fiber optitcal, and signal/control applications. This type of rigid connection system typically requires fewer pieces, and can require less space than a screw-terminal connection. Communication terminal blocks for Ethernet applications typically have a protective insulation that prevents the connective pins from shorting. Similarly, they may have insulation slots that protect against excess thermal or electrical exposure.

Wire-to-Board Connectors

Wire-to-board terminal blocks are those that connect wires and other small parts to a printed circuit board (PCB). These generally provide a reliable and secure connection, and they are used in consumer and commercial products alike. Many wire-to-board terminal blocks are designed to avoid degradation from contact-normal force as the connector is used. The conductors in these can be protected further through insulation slots in the design.

Solar-Panel Systems

Terminal blocks for solar-panel systems are those that establish a reliable electrical connection between several components in the solar panel array. Typically, these include everything from the panel to the solar light and from the frame of the panel to wiring systems. Solar-panel terminal blocks are often made to resist water, dust, and moisture. They are also made with weather-resistant materials that guard against ultraviolet light and other extreme conditions.

Specialized terminal blocks are those that are designed with application fields and working principles in mind. Hazardous location blocks are designed to prevent spark creation, while surface-mount blocks are made to minimize size. Communication terminal blocks provide data protection, while those for wire-to-board connections assist with reliable circuits. Solar-panel terminal blocks maintain a secure connection between panel frames, wiring systems, and solar lights. Together, these specialized terminal blocks provide reliable, secure connections in a variety of applications.
