Jumper Wires

A jumper wire is an electrical wiring component that allows for two or more electrical circuits to be connected together. Jumper wires are made of insulated wires that can be bent, twisted, and formed into various shapes and sizes. The common type of jumper wires are round, flat, and flexible. It is used to link two sets of electrical contacts or terminals for signal transfer or power supply. Jumper wires are used in a variety of applications, such as interconnecting printed circuit boards, solderless breadboard prototyping, relay-based circuits, optical communication systems, and telecommunication systems.

Jumper wires are available in various lengths, with different thin and thick diameters, and colors. While jumper wires are typically used with electronics, they can also be used with automobile wiring. When used with automotive wiring, jumper wires usually come in red and black colors to indicate positive and negative power supply.

Working Principle

Jumper wires usually consist of exposed conductive wires with insulation. The ends are used to connect two wires together, creating a single route for electrical current to flow between the two wires. It enables the connection of two wires without creating a permanent link between them, allowing the wires to be re-used in another circuit. When the jumper wire is connected, the electrical connections establish a closed loop circuit, which allows electricity to transfer from one connection to the other. Jumper wires are ideal for creating a prototype circuit and testing various electrical paths in a variety of permanent and temporary connections.

Pre-Crimped Leads

Pre-crimped leads are quick electrical connections used for a wide range of applications including automotive, industrial, and consumer electronics. Pre-crimped leads are pre-formed metallic wires with a crimp at one end and an open connection at the other end. The main advantages of pre-crimped leads are that they tend to provide greater electrical conduction reliability, reduce assembly time for manufacturers, and improve the overall reliability of a particular product. In addition to providing reliable conductivity, pre-crimped leads can also be used to reduce overall assembly time.

Pre-crimped leads can be used to terminate printed circuit boards (PCBs) and other components easily, making them ideal for quick assembly operations in which manufacturers need to process large numbers of components. For example, pre-crimped leads are commonly used on PCBs to connect switches, relays, and other components. Pre-crimped leads are also used in automotive applications for wiring and electrical connections between components. They are usually available in either aluminum or tin-plated variation for improved conductivity.

Working Principle

The working principle of pre-crimped leads is based on the crimping process which is used to create a solid mechanical connection between two wires. The crimping process involves squeezing the metal of the wire together, forming a solid connection between the two wires. This process is not only used to connect two wires, but also to attach the wire to an electrical terminal, such as a switch, relay or connector. The metal crimp at the end of the pre-crimped lead is designed for a specific terminal size, so that the crimped lead can be easily inserted into the terminal, providing a secure connection that is reliable and easy to install. Once the pre-crimped lead is inserted into the terminal, the metal crimp provides a secure electrical link between the opposing terminals.
