Spade connectors are commonly used in electrical and electronic applications to provide a secure and reliable connection. They are called “spade” connectors because of their shape, which resembles a spade or a shovel. These connectors have a flat, blade-like metal contact that is inserted into a corresponding female receptacle or terminal. The connection is then secured by crimping or soldering the connection point.
When measuring spade connectors, two important dimensions are typically considered: the width and the thickness. The width refers to the distance between the two sides of the connector blade, while the thickness refers to the distance from the top surface of the blade to the bottom surface. These measurements are crucial in determining the compatibility of the connector with the receptacle or terminal it will be inserted into.
Spade connectors come in various sizes and are classified using different sizing systems. One common sizing system is based on the American Wire Gauge (AWG), which measures the thickness of the wire. The sizes range from the smaller 22 AWG up to larger sizes like 8 AWG. Another sizing system is based on millimeters or inches, where the width and thickness are measured using a caliper or ruler.
It is important to measure spade connectors accurately to ensure proper fit and functionality. Using the wrong size can result in loose connections, poor electrical conductivity, and potential safety hazards. Therefore, it is recommended to refer to manufacturer specifications or consult an expert when measuring spade connectors for a specific application.
Overview of spade connectors
Spade connectors are widely used in electrical and electronic systems to provide a secure connection between wires and terminals. They are named after their shape, which resembles a spade or a fork with a flat, rectangular or circular base and two prongs.
These connectors are available in various sizes, designs, and materials to accommodate different applications. The size of a spade connector is often measured in terms of the width of the base or the diameter of the hole in the base. Common sizes include 2.8mm, 4.8mm, and 6.3mm.
Spade connectors are typically made of materials such as copper, brass, or stainless steel, which offer excellent electrical conductivity and corrosion resistance. The prongs are usually insulated with a plastic coating, such as nylon or PVC, to provide electrical insulation and prevent short circuits.

Choosing the right size
When selecting spade connectors, it is important to choose the right size to ensure a secure and reliable connection. Spade connectors come in various sizes, which are typically determined by the width of the terminal or stud they are designed to fit.
The size of a spade connector is typically measured in terms of its width, which is denoted by a standardized code. The most common sizes of spade connectors range from 2.8mm to 10.5mm. It is important to note that these measurements refer to the width of the connector itself, not the size of the wire it can accommodate.
Choosing the right size of spade connector is essential to ensure a proper fit. If the connector is too small, it may not securely fasten to the terminal or stud, resulting in a loose connection that can cause poor electrical conductivity or even cause the wire to come loose over time. On the other hand, if the connector is too large, it may not fit into the terminal or stud at all, rendering it useless.
To determine the appropriate size of spade connector for your application, you will need to measure the width of the terminal or stud that the connector will be attached to. It is important to use calipers or a similar measuring tool to get an accurate measurement. Once you have the measurement, you can refer to a spade connector size chart to find the corresponding size.
It is also important to consider the gauge of the wire that will be used with the spade connector. While the width of the spade connector refers to the size of the connector itself, the gauge of the wire refers to the thickness of the wire. It is important to choose a spade connector that is compatible with the gauge of the wire you will be using to ensure a secure and reliable connection.
| Spade Connector Size | Width (mm) |
|---|---|
| 2.8mm | 2.8 |
| 4.8mm | 4.8 |
| 6.3mm | 6.3 |
| 10.5mm | 10.5 |
It is advisable to consult the documentation of your specific equipment or consult a professional if you are unsure about the appropriate size of spade connector to use for your particular application.
Measuring the width
Spade connectors are measured by their width or the distance between the two prongs. The width of the connector is typically indicated in millimeters (mm) or gauge (AWG).
To measure the width of a spade connector, you will need a caliper or a ruler with millimeter markings. Start by placing one end of the caliper or ruler on the outer edge of one prong, and extend it to the outer edge of the opposite prong. Take note of the measurement displayed on the caliper or ruler.
If you are using a ruler, ensure that it is aligned with the edges of the prongs to get an accurate measurement. Measure from the outer edge of one prong to the outer edge of the opposite prong.
Once you have the measurement, you can refer to a spade connector size chart or spec sheet to determine the corresponding width in millimeters or gauge. This will help you identify the correct size spade connector for your application.
It is important to note that spade connectors come in various widths to accommodate different wire sizes. Choosing the correct width is crucial to ensuring a secure and reliable connection.
Measuring the depth
When it comes to spade connectors, it’s important to measure the depth accurately. This measurement refers to how far the spade connector extends into the terminal or socket it is being connected to.
To measure the depth, you will need a ruler or calipers. Start by placing the ruler or calipers at the base of the spade connector, where it meets the terminal. Carefully extend the measurement tool along the length of the connector until you reach the end. Take note of the measurement in millimeters or inches.
It’s important to measure the depth accurately as it ensures a secure and reliable connection. If the depth is too short, the connector may not make proper contact with the terminal, resulting in a weak connection. On the other hand, if the depth is too long, the connector may not fit properly into the socket, causing connection issues or even damage to the terminal.
Remember to double-check your measurements before purchasing or installing spade connectors to ensure compatibility with your specific application. Taking the time to measure the depth accurately will help you avoid any potential problems and ensure a successful electrical connection.
Compatibility with wire gauge
When choosing spade connectors, it is important to ensure that they are compatible with the wire gauge you are using. Wire gauge refers to the size or thickness of the wire and is typically measured in American Wire Gauge (AWG).
Spade connectors are available in different sizes, which are matched to specific wire gauges. It is crucial to choose a spade connector that is compatible with the size of your wire to ensure a secure and reliable connection.
If you have a smaller wire gauge, such as 18 AWG, you will need a smaller spade connector size. On the other hand, if you are working with a larger wire gauge, such as 10 AWG, you will require a larger spade connector size.
Using an incompatible spade connector can result in a loose or unreliable connection, which can lead to electrical malfunctions or even a safety hazard.
