Jumper Wires

0039000038-10-S0 Application Field and Working Principle

Jumper wires, also known as jumpers, isolation bridges or strap-lines, are electrical wires used for the connection between two electrical points or components. Jumper wires are commonly used for short-term connections between PCB pins, test points, and prototyping, and for longer-term connections in applications such as rework.Jumper wires differ from traditional crimp, screw, or solder wire terminations due to their mobile nature and easy connection and disconnection of circuits. These wires are made from the same platable and high-quality copper wire as traditional crimped, screw, and soldered leads, and therefore deliver the same power rating, current, and voltage capabilities as other types of electrical wire connections.Jumper wires have an insulated core with two stripped ends and two crimp terminals on each end. The terminals are press-fitted onto the core and crimped with special crimping tools, providing a reliable and safe electrical connection whose structure and integrity are maintained over long periods of time. In addition, the press-fitted design ensures that the connection remains stable even when subjected to mechanical vibrations or environmental factors.The insulated core and terminals also provide protection against electrical shock and other hazards. The insulation is designed to transmit minimal current through the wire, allowing it to be used safely in any environment without disrupting other nearby circuits.Jumper wires are available in a variety of sizes and colors, depending on the application. The most common sizes of jumper wires include 18 AWG, 24 AWG, and 30 AWG. Jumper wires are also available in specialized varieties such as insulated cables, flat cables, and double-shielded cables.The most common colors for jumper wires are yellow, green, black, and brown. The most common color codes for electrical wires apply to jumper wires as well; a white wire generally indicates a neutral, a black or brown wire indicates a hot, and a green wire indicates a ground connection.Jumper wires are essential in many fields of electronics and electrical engineering. They are an essential tool for prototyping, rework, and other applications where a temporary electrical connection is required. The versatility and ease of use of jumper wires make them one of the most widely used electrical components in the world.

Pre-Crimped Leads

Pre-crimped leads, also known as crimped contacts, are contacts already crimped at one end to the same size wire. This type of electrical contact is designed to be quickly and securely joined onto machinery, such as an electronic printed circuit board (PCB), which then requires no further soldering or other connection methods.Pre-crimped leads are made using specialized hand crimp tools. The process starts by cutting the wire to the desired length, and then stripping or cutting the insulation so that the bare wire is exposed. A special hand crimp tool is used to press the contact onto the exposed wire. This creates a sturdy and secure connection.Pre-crimped leads are typically used in applications where quick assembly is required, such as industrial instrument control panels or vending machine wiring. Pre-crimped leads are also used in medical and automotive applications.Pre-crimped leads come in a variety of sizes and styles, depending on the application. The most common size of pre-crimped leads is 20-22AWG. The most common styles of pre-crimped leads are straight, push-on, and mini ferrules.Straight pre-crimped leads come in insulated and uninsulated form. The insulated leads are equipped with insulation so that they do not create a short-circuit when the contact is exposed. The uninsulated leads are designed to be used in applications where the contacts will not be exposed.Push-on pre-crimped leads are quick to install and do not require any additional tools. They are typically used on printed circuit boards, as they require no soldering to be connected. Mini ferrules are typically used to connect electrodes or sensors to power terminals.Pre-crimped leads are a relatively inexpensive and efficient solution for connecting components in an electronic system. They are easy to use and require minimal effort to install, making them essential for quick installation and prototyping applications.
