Spade connectors are a type of electrical fastener commonly used in the terminal industry. They are used to easily join two electrical components together, making them ideal for a range of applications including automotive, appliance and industrial. This article will provide an in-depth look at the 33221 spade connector as well as its application field and working principle.

33221 Spade Connector

The 33221 spade connector is a single-wire, tapered barrel crimp connector. It features a 0.28" OD tapered barrel with a 0.185" ID inner contact, making it suitable for use with both standard and metric wire sizes. It also has a barrel-locking system that provides a firm and durable joint.

The 33221 spade connector is a heavy-duty, commercial-grade component and is rated up to 24VDC and 20A. It is designed to meet and exceed UL and CSA standards and is UL certified. The 33221 is widely used in industrial and commercial settings due to its robust design and reliable performance.

Application Field

The 33221 spade connector is widely used in a range of industries due to its robust and reliable performance. It is commonly used in automotive, appliance, lighting, HVAC, and industrial applications. It is also a common choice for power connections in control panels, including panels containing motor starters, drive controllers, and PLCs.

In automotive applications, the 33221 spade connector is commonly used for wiring and power connections in a range of components, including alternators, starters, and wiring harnesses. In lighting and appliance applications, the connector is frequently employed to join wiring and power connections for LED lighting, floodlights, and other lighting fixtures.

The 33221 spade connector is also an ideal choice for power connections in industrial applications. It is used for wiring motor starters, drive controllers, and other industrial equipment. It is also a popular choice for commercial and residential HVAC applications, where it provides secure and reliable connections for air conditioning units.

Working Principle

The 33221 spade connector features a tapered barrel design that is crimped onto the exposed ends of the wire. This crimped joint ensures that the connection is mechanically secure and electrically conductive. This type of connection also provides a firm and reliable bond that will not corrode or break down over time, even in harsh conditions.

Once the 33221 spade connector has been crimped onto the exposed ends of the wire, the barrel-locking system can be engaged to provide a secure and reliable joint. The barrel-locking system is composed of a series of external teeth that mate with corresponding internal teeth. This system allows the connection to be easily engaged and disengaged without the need for additional tools.

The 33221 spade connector is an ideal choice for a range of applications due to its robust and reliable design. This connector provides a secure and reliable connection that is designed to withstand harsh conditions and is UL certified. With its wide range of applications, the 33221 spade connector is an ideal choice for a variety of electrical connections.
