Spade Connectors, such as the 52730 series, are widely used in multiple applications in various industries, ranging from consumer electronics to commercial and industrial applications. Their popularity is due to their cost effectiveness, small size, versatility, and ease of use. The 52730 series features a unique design which is the most widely-used spade connector in the market.

What Is a Spade Connector?

A Spade Connector is a simple friction fit electrical connector typically used to join conductor and wire together. The contact end of the spade connector features two sets of round “spades”, a tighter fitting “master spade” and a larger loose fitting “slave spade”. The master spade is designed to enter the slave spade first and lock it into place. Once in place, the Mate spade is prevented from accidentally slipping from the slave spade thanks to two opposing “teeth” from the master spade, which wedge against the edge of the slave spade.

52730 Application Field and Working Principle

The 52730 series Spade Connectors are used in a variety of applications such as consumer electronics, commercial appliances, automotive equipment, audio/video equipment, lighting fixtures, medical apparatus, industrial sensors, and aerospace, among many others. The 52730 series is also approved for use in hazardous and wet locations, where traditional screw terminals may not be suitable.

As for its working principle, the 52730 series spade connectors are designed to be installed by simply pressing the master spade into the slave spade. The master spade has a “beveled” edge which allows it to smoothly slide into the slave spade, locking it in place with the opposing “teeth” from the master spade. This secure fit ensures high contact pressure between the spades and prevents accidental slip off.

Once pressed into place, the mating edge of the spade connector is then ready to accept the wire or conductor, which is then friction fit into the mating edge. The wire is usually fastened into place with a tool such as a crimper. Once in place, the contact between the spade and the wire is tight and secure.

Additional Features of the 52730 Series

The 52730 series spade connectors have a number of extra features which make them appealing to a wide range of applications. For example, the spade connectors are made from an alloy of copper and tin, which enables them to be both strong and flexible, allowing them to be used in a variety of applications. Furthermore, the 52730 series spade connectors are designed to be used in areas where there may be exposure to hazardous materials, such as fuel, oil, or acid. These spade connectors are also suitable for use in wet locations, thanks to a seal on the back of the spade.

The 52730 series also features a "reed" style option. The reed style design allows the spade connector to be used in areas where there is limited space, such as in tight corners or in areas where the full size 52730 series cannot be used. The reed style spade connector is also designed for applications where vibration or shock may be an issue, as the reed design allows for more flexibility and reduces the risk of the conductor becoming disconnected.

Conclusion

The 52730 series Spade Connectors are immensely popular in many applications, due to its cost-effectiveness, small size, and versatility. They are capable of being used in a variety of hazardous and wet locations, and feature a number of additional features such as their reed style design. Whether it be in consumer electronics, commercial appliances, automotive equipment, or in industrial settings, the 52730 series spade connectors can be found in many places.
