Jumper Wires and Pre-Crimped Leads 0039000040-12-W0 Application Field and Working Principle

Jumper Wires

Jumper wires are basically insulated wires and are used for making connections between circuits on breadboards, printed circuit boards and other types of electronic circuits. These wires are commonly used in prototyping circuits, in computer and electronic test equipment, in auto-testing devices and in circuit board development. They are available in various sizes and shapes and come with different insulation material such as PVC, Polyethylene, Teflon and ABS. Jumper wires are used to connect different components within a circuit without the need for soldering. This makes the circuit effortless to modify and also increases its reliability.The main working principle of jumper wires involve the junction of two conductive components called the wire and the conductor. The conductor is usually made of copper and the wire is insulated material. The jumper wires are generally connected to the conductor by means of soldering or crimping. The use of crimping is best suited for making small or complex circuits. Soldering is best reserved for joining larger components.

Pre-Crimped Leads

Pre-crimped leads are electrical wires with connecting terminals that have already been crimped. This type of wiring is most common in electronic components such as relays and switches. The terminals are crimped to the wires and then soldered to the internal circuit. Pre-crimped leads provide a way to make reliable connections without the need to solder each wire separately.The working principle of pre-crimped leads involves a very simple connection and disconnection process. The wire and the terminal are pre-crimped together and connected to each other. The terminal and the wire are held together by a mechanical connection. Connecting a pre-crimped lead to a device is simply a matter of plugging it in. Disconnecting, on the other hand, is simply a matter of unplugging.Pre-crimped leads provide a reliable connection for a variety of electronic devices because all the wires are connected simultaneously, thus providing a secure connection with minimal effort. This type of wiring is quite common in automotive wiring, switch panels and device assemblies.

Conclusion

Jumper wires and pre-crimped leads are both electrical wires that serve different purposes. Jumper wires are used to connect sketches or circuits on breadboards as well as other electronic circuits. Pre-crimped leads are primarily used to connect electrical components such as relays and switches. Both types of wires provide secure and reliable connections and are easy to use and maintain.
