Terminal blocks are a type of electrical connection that allows users to create more permanent connections between circuits, without the need for constant reassembly. These blocks utilize a metal or plastic square, with two or more holes that are lined up with a series of contacts. A screw, pin, or other connection device is inserted into the hole, and lined up with the contact points to complete the circuit. The advantage of terminal blocks is that they provide a secure method of connecting and disconnecting circuits, and are easy to increase or reduce, depending on the specific needs of the application.

One of the most popular accessories for terminal blocks is jumpers. A jumper is a metal, plastic, or composite part that connects two or more screws, pins, or other contact points inside the terminal block. Jumpers can be used to increase the capacity of a block, to form an electrical pathway for a specific circuit, or to ensure the circuit operates properly. Common types of jumpers are available in solid line and multiple lines formats, depending on the needs of the application.

In order to properly utilize jumpers with terminal blocks, it is important to be familiar with their fields of application and how they work. For example, a solid line jumper is often used when two screws within the same block need to be connected. Whereas, a multiple line jumper is used when more than two metal or plastic components in the block need to be connected together. In either case, the jumper creates a secure bridge between contacts, allowing the circuit to be operated safely and efficiently.

There are a number of other fields of application for jumpers, including the use of them to transfer electrical power between two separate metals or plastic components, join electric wires, or provide an additional connection between a terminal block and a circuit. In all of these cases, the ability of the jumper to securely bridge two or more electrical contacts is essential.

It is also important to consider the safety of using jumpers with terminal blocks. The safe operation of the terminal and jumper relies on the quality of the components used, and the environment in which they are used. A properly installed jumper should make an electrical connection that is safe and reliable. To ensure their connection is stable, users must make sure any screws or pins involved are properly tightened, and the jumper itself is securely placed in its position. Additionally, jumpers should be checked regularly for signs of corrosion or wear, as well as ensuring that no debris has been left inside the terminal block.

Overall, understanding the use of jumpers with terminal blocks, and their various application fields and working principles, can help users to create connections that are reliable and safe. Additionally, familiarizing oneself with how jumpers can be used with other connection systems, such as insulated-gate bipolar transistors, will help users further increase the versatility and efficiency of their connections.
