Terminals - Spade Connectors

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

Type	Functional Features	Application Examples
Insulated Spade	Plastic housing prevents short circuits	Automotive fuse boxes
Non-Insulated Spade	Bare metal contact for space-constrained applications	Industrial control panels
High-Temperature Spade	Heat-resistant materials up to 200 C	Engine compartment sensors
Metric/SAE Standard	Differentiated by blade width (6.3mm/4.8mm)	Global automotive systems
Quick-Disconnect Spade	Tool-free manual connection/disconnection	Consumer appliance maintenance

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

Parameter	Typical Range	Importance
Current Rating	10-50A	Ensures thermal stability under load
Voltage Rating	250-600V	Prevents dielectric breakdown
