Jumper Wires, Pre-Crimped LeadsCable assemblies are a type of wiring harness that consist of cables or wires that are bound together using a variety of methods, such as ties, straps, or specialized connectors. Jumper wires, also known as jumper cables, are short lengths of wire that are used to connect two points in a circuit. Pre-crimped leads are wires that have already been crimped with a connector at one end, allowing them to be easily attached to a circuit board or other electronic component. All of these components are used in a variety of electrical and electronic systems, including computers, appliances, and industrial equipment.
