Terminal Blocks - Accessories - Jumpers

Terminal blocks are electrical blocks with terminals to connect wires to run electric power or signals to and from electric equipment. Accessories, such as jumpers, are used to improve the usability of those terminal blocks. Jumpers are simple clips that connect two or more points of the terminal block. They provide the simplest and least expensive way of wiring and connecting components in an electrical circuit.

Jumpers – also known as link plugs, link caps and link clips – are used to join two adjacent terminals together and allow one or more circuits to be passed between them. This allows a complex and interconnected wiring to be effected without the need for individual connections. In this way they save significant amounts of time and money when compared with soldering, crimp connections and soldering irons.

The simplest and most cost-effective application of a jumper is in the implementation of an in-circuit tester for analog and digital circuits. Many analog meters, such as oscilloscopes, are designed with circuits which must be bridged in order to apply the signal from the device to a test point. Similarly, with digital circuits, test points require a connection between two or more terminals in order to provide an accurate reading. Jumpers are the ideal solution, providing the shortest and most reliable connection between the terminals without the need for additional equipment. These same jumpers may be reused multiple times, as they can be easily disconnected and reconnected.

Another application of jumpers is in home and office wiring. Some residential wiring circuits require a connection between two or more conductors to complete the circuit. In this scenario, it would be difficult to use a conventional wire-joining technique, and installing a jumper ensures that the connection is made quickly and without fuss. This is especially the case for multi-zone electrical systems, where multiple switch boxes are connected together.

Finally, jumpers are used to board test integrated circuits. This is a process used to help troubleshoot IC circuits. The method involves connecting one or more test points on the IC with a jumper, allowing a voltage or current to be applied at the test point to measure the response of the circuit. The feedback obtained helps to identify faults and weaknesses in the circuit that might otherwise be impossible to uncover. This feedback allows for adjustments to be made before the finished product is sent out to the customer.

In conclusion, jumpers are an important accessory for any electrical project. They can be used to join terminals and circuits together, to help troubleshoot complex circuits, and to make connections in home wiring without the need for additional equipment. Through their use, time and money can both be saved, making them an essential tool for any electrical repair or installation.
