2-282836-1 or more generally referred to as a Wire-to-Board Terminal Block is an extremely useful electrical connection element such that helps make connections between two wire-ends with a secure and reliable connection. A common application of these terminals can be found as circuit breakers, switches, and other similar connection points.

These terminal blocks are generally manufactured from non-hygroscopic thermoplastic compounds such as Polyvinyl Chloride (PVC) or more frequently, from polypropylene compounds that possess good electrical capabilities. Originally, these Wire-to-Board Terminal Blocks were designed for pin-to-pin connections but over the years, the design was changed to accommodate wire-to-wire connections using a spring-loaded terminal contact.

From a construction standpoint, these Wire-to-Board Terminal Blocks are typically composed of an insulator and a series of contacts housed within the insulator. These contact points that reside within the insulator are typically male or female pistons which allow for a secure connection between wires.

From a functionality standpoint, these Wire-to-Board Terminal Blocks work by expanding the contact surfaces at the pistons within the insulator when they are pressed against the wires. This configuration of Wire-to-Board Terminal Blocks allows for a secure and reliable connection that is far less likely to corrode or malfunction over time.

In addition to the common applications, Wire-to-Board Terminal Blocks are also seen in a variety of other applications such as wiring harnesses for automobiles and motorcycles, diesel engines, signal-processing equipment, lighting systems for commercial buildings, air-conditioners, and railway systems.

These Wire-to-Board Terminal Blocks possess an array of superior properties such as high-voltage & current ratings, superior insulation resistance, good tolerance to temperature, as well as good mechanical strength. As a result of these characteristics, they are widely used in various commercial and industrial applications where reliable connection is paramount.

The terminal blocks can operate in a wide range of temperatures ranging from -40°C to +125°C, depending on the material properties of the insulators. The current-carrying capability of these blocks can range from 10A to 30A, while the voltage-carrying capacity is proportional to the insulation resistance of the material used.

These days, Wire-to-Board Terminal Blocks are available in a variety of sizes and shapes depending on the application. While the standard sizes are generally sized 50mm x 25mm and 25mm x 25mm, larger blocks are also available for applications where large electrical power needs to be transferred. Common shapes are the straight, angle and the curved configurations.

In conclusion, Wire-to-Board Terminal Blocks are extremely common and useful devices used for a variety of applications. They provide a secure electrical connection between two wires that is extraordinarily durable and dependable. These blocks are extremely useful in a variety of different applications, and their properties and ability to withstand high temperatures and large voltages make them ideal for a wide variety of applications.
