Introduction

22-28-4075 is a type of rectangular connector with male pins, also known as male headers. This connector is commonly found in industrial applications such as in motors, switchgear, and PLC systems. It is used to join two polarized wires, meaning that it cannot be used to connect two mismatched wires. In addition to its industrial applications, it is also widely used in the hobby robotics, home automation, and DIY electronics market.

Applications

The 22-28-4075 is a versatile connector that can be used for a variety of applications. Power equipment manufacturers may take advantage of the connector to couple motors and switchgear, as it is capable of withstanding both 12 and 24 volts. This connector can be used in the automotive industry for the wiring of headlights, stereos, rear view mirrors, and footwell lighting. In the hobby robotics community, the connector is often used to connect motors and servos, while also providing an easy connection point for LED and other components.

Advantages

The 22-28-4075 has some amazing benefits for its end users due to its versatile performance capabilities. The most prominent advantages are its error-proof design and fast disconnect/reconnect feature. The male pins of the connector are incidently always aligned with the female connectors, making it virtually impossible to connect two wires in the wrong direction. This error-proof design has saved many hobbyists replacing fried components due to mis-wiring.The fast disconnect feature of the connector facilitates the replacement of components as the connector simply needs to be pulled off the wires. This feature is especially useful when troubleshooting, as it allows the user to easily disconnect components in order to isolate the problem from the rest of the system.

Design

The 22-28-4075 is composed of a black housing and a set of 4 male pins. The housing itself is made of an ABS thermoplastic material which is highly durable and designed for harsh environmental conditions. The pins themselves are made of brass and feature a gold-plated finish.The design of the connector helps to prevent heat damage and increases the life of the device. This is due to the gold-plated pins being in direct contact with the female contacts. The gold-plating helps to provide a secure connection between the two surfaces, reducing the risk of heat build-up from friction.

Working Principle

The 22-28-4075 works by using a combination of a metal spring and a plastic piece to maintain tension while the connection is being made. The spring is placed between the two metal contacts, providing a stop point midway through the connection. This allows the contacts to properly align and seat correctly on the opposing surface.The 23-28-4075\'s design also helps to prevent unintended disconnections. This is due to the fact that the spring is positioned directly between the contacts, ensuring that they remain connected. This eliminates the risk of accidental disconnections due to vibrations or shock.

Conclusion

The 22-28-4075 is an incredible tool for users in the electrical engineering and hobby robotics markets. Its error-proof design and fast disconnect/reconnect features have made it an essential part of many projects. Its versatile design and durable construction make it suitable for a variety of applications from industrial systems to even the hobbyist market. Understanding its working principle helps to provide users with insights into how the connector works and how they may be able to improve upon their current design.
