1. Overview

Spade connectors are electrical terminal devices featuring a flat, fork-shaped contact interface. They enable secure and removable connections between wires and electrical components. Widely used in automotive, industrial, and consumer electronics, these connectors ensure reliable power transmission while allowing easy maintenance and replacement.

2. Main Types & Functional Classification

3. Structure & Composition

Typical spade connectors consist of:

• Metal contact blade (phosphor bronze or beryllium copper)
• Insulation housing (PVC or nylon)
• Contact surface plating (tin, silver, or gold)
• Wire crimping section with strain relief

4. Key Technical Specifications

5. Application Fields

Major application areas include:

• Automotive systems (starter motors, relays)
• Industrial machinery (PLC interfaces)
