Jumper Wires

Jumper wires are flexible, often multi-strand cables with pre-crimped leads at one end, that are used in prototyping and testing electronic assemblies. They commonly feature 30 AWG (American Wire Gauge) stranded wire in various lengths, colors and insulation thicknesses. The leads are typically made from alloy steel and are plated with tin for enhanced corrosion protection. Depending on the application, jumper wires are available with male, female, and pin-style connections.

Application

Jumper wires are mostly used in prototyping and debugging layouts, as they allow for components to be connected in a variety of ways. In addition, jumper wires help to bridge the gap between an unfinished circuit board and a functional unit. An example of a common application is when troubleshooting a board or assembly, a jumper wire can be connected to two points on the board and then tested with a meter or oscilloscope to check for errors.

Working Principle

The working principle of jumper wire is relatively simple. It typically consists of two tin-plated, alloy steel leads connected to a multi-stranded, flexible wire. Current flows from the first lead to the second lead through the wire. Depending on the application, the leads can be male, female, or pin-style connections. For example, a pin-style jumper connects a specific circuit point on a board to another point, when connected, current flows between the two points. This is typically used to test a board or assembly\'s continuity.

Pre-Crimped Leads

Pre-crimped leads are small, durable connectors that work with stranded cables used for prototyping or testing electronic assemblies. These leads come pre-crimped on one end, allowing for quick and easy connection to a stranded wire. Pre-crimped leads are available in a variety of sizes and with a variety of terminal styles (male, female, and pin-style connections).

Application

Pre-crimped leads are used in a variety of applications where a quick and reliable connection to a stranded wire is needed. For example, they are commonly used to quickly and easily connect a test cable to a board or an assembly. They can also be used to connect a power supply or other external device to an assembly. Pre-crimped leads reduce installation time and provide a secure, reliable connection.

Working Principle

The working principle of pre-crimped leads is simple and efficient. The pre-crimped cable is placed on one end of the lead and then crimped to the other end. This crimping action creates a secure connection between the two points and ensures that current flows from one point to the other. Pre-crimped leads can be used with either male or female connectors, depending on the application.
