Terminal Strips and Turret Boards 15221 provide a wide array of applications in electrical and electronic equipment. Typically used as part of an assembly between a wire and equipment, they provide an effective connection while helping protect the wire and equipment from damage. This article looks at the 15221 application field and its basic working principle.

What are Terminal Strips and Turret Boards?

Terminal strips and turret boards are electrical or electronic components that enable wires to be connected or disconnected from equipment without the need to solder the connections. They also provide insulation between the components and the equipment to protect both from damage. Terminal strips consist of rows of terminals or pins which are placed congruently along a board or strip. The terminals are then connected together with the use of soldering or insulation material, to create a secure but manoeuvrable connection. Usually, components are connected using screws or clips. Turret boards are much the same as terminal strips, except they feature larger connectors which are designed to form a single connection that is easily disconnected and reconnected.

15221 Application Field and Working Principle

The 15221 series of terminated and turret boards are typically used in a range of applications involving detached equipment and 14 and 16-pin connectors. The terminals are designed to reduce the potential entry of current flowing between the terminals and the board or strip during operation. This property helps minimize any damage to connected equipment due to short circuits or arcing, as well as providing adequate insulation and preventing signal loss. As a result, the 15221 boards and terminals provide a reliable and durable connection, reducing risks of wire or equipment damage.

The 15221 board and terminal strip connections are sealed to help prevent against moisture damage or corrosion. The connections are very reliable, and can be used to connect difficult to solder points or terminals. As such, they are suitable for low-stress environments, such as in the military, or in harsh industrial applications. The 15221 boards are also compatible with a range of products, including solderless breadboards, test sockets, SCR assemblies, and 16-pin plated through holes.

The 15221 boards feature external bases which are used to construct the connection with the board. The base board enables the user to secure the board to the equipment. The bases can accommodate different sizes of screw holes, depending on the size of the board. Once the base is securely attached to the board, the user can then attach a cable — usually an IC connector — to the board. The terminal board also features a tab system, allowing the user to make and break connections easily, as well as provide further protection against external interference.

Conclusion

The 15221 terminal strip and turret board are highly effective and reliable pieces of equipment, providing a secure connection between equipment and wires. Their size, versatility, and durability make them an ideal solution for a wide variety of applications, particularly those involving harsh environments. Together with the insulation properties, simple yet effective tab system, and soldering free connection construction, they provide the perfect protection against wire and equipment damage.
