Jumpers are a type of terminal block accessory that is both flexible and efficient. The devices are used to create flexible electrical connections between points, and are used in a wide range of applications. This article will explain the workings and applications of jumpers in the field of electrical engineering.

Types of Jumpers

The type of jumper used depends on the application and the voltage requirement associated with the intended circuit. The common types of jumpers include:

• Bare-Bare Jumpers: These are terminals that come without insulation, and are suitable for low voltage applications.
• Insulated Jumpers: These are insulated terminals and are used in high voltage applications due to their superior insulation qualities.
• Wire-Jumpers: These are commonly used as a form of shorting devices or as conductors between different parts of a circuit.
• Pinouts: Pinouts are special type of jumper with unique pin configurations allowing them to connect two components more closely.

Applications

Jumpers are used in a variety of applications such as connecting two batteries, connecting a supply to controller boards, and connecting transistors and other components within a circuit. They are also used to create a bridge between an insulated circuit and an uninsulated one.

Jumpers are also used in the telecommunications industry to connect two pieces of hardware, such as a router and a modem, or a TV and a set-top box. In this application, the jumper is used to bridge the gap between the two different types of hardware, allowing a seamless connection.

Jumpers also come in handy when testing or troubleshooting certain circuits and components. By creating jumper cables, technicians can quickly and easily bypass certain components or circuits in order to diagnose and locate the source of the problem.

Working Principle

Jumpers are usually put together using two or more conductive strips that are soldered together in order to create a bridge between two points. In some cases, a single pin can be used in order to form the bridge. In each case, the pins of the jumper are usually pointed in opposite directions in order to ensure a perfect connection.

Once the jumper is in place, the current flows through the pins and joins the two points. This process creates an electrical connection that can be used to create a circuit or facilitate the transfer of electricity between two separate parts of the same circuit.

Conclusion

Jumpers are an incredibly useful tool in the field of electrical engineering and are used in a variety of applications. They are a simple yet effective way of creating flexible electrical connections between two points, and are well-suited for use in low and high voltage scenarios. By understanding the working principles and applications of jumpers, engineers can ensure they are using the most appropriate type of jumper for their particular scenario.
