Rectangular connectors, also known as rectangular plug and sockets, are an extremely versatile connector type that are widely used in a variety of commercial, industrial and aerospace applications. In addition to their variety of sizes, there is an even wider range of housing materials and styles to choose from. Rectangular connectors come in two- and three-conductor formats, and they are typically rated for up to 15amp current. In order to best assess the application and working principle of the 39-01-2020 rectangular connectors, it is first necessary to explore the various types of housings available.

The first type of housing is backshells, which are plastic or metal shells that attach to the rectangular connector itself and provide strain relief and environmental protection. Backshells also provide additional mechanical support to the connector, reducing the possibility of accidental disconnection or cable damage. Rectangular connectors with backshells are typically used for applications that require additional protection against physical and environmental factors, such as exposure to heat, dust, humidity, and vibration.

The second type of housing is crimp rings, which are plastic or metal rings that fit around the contacts of the connector and provide additional insulation and strain relief. Crimp rings are typically used when connecting a cable to a connector, as they reduce the possibility of accidental disconnection or damage to the contacts. They also provide additional protection against environmental conditions.

The third type of housing is shells, which are also plastic or metal shells that attach to the rectangular connector itself and provide additional environmental protection. Unlike backshells, shells do not provide any additional mechanical support to the connector. They are typically used for applications that do not require additional mechanical support, such as shielded applications or applications with large amounts of EMI emissions.

The fourth type of housing is gaskets, which are rubber or neoprene gaskets that provide additional insulation and environmental protection to the rectangular connector. Gaskets are typically used for applications that require additional insulation from environmental factors, such as exposure to heat, dust, humidity, and vibration. Gaskets also provide additional protection against EMI and radio frequency interference.

Once the various types of housings have been determined, the next step is understanding the application and working principle of the 39-01-2020 rectangular connectors. Generally speaking, rectangular connectors are comprised of two or three conductors and are typically rated for up to 15amp current. The number and type of conductors and power ratings of the connector will depend on the chosen application and type of connector.

When two conductors are used, one conductor is typically a signal wire and the other is a ground wire. The two conductors are connected together to form a single circuit. When three conductors are used, each conductor typically carries a separate signal. The two signal wires are connected together and the third conductor is used as a ground.

Rectangular connectors are also designed with a variety of contact configurations depending on the application. Common contact configurations include the Channel, Slot, and Post connectors. The channel connector has two or three open sides and is typically used with baluns and surge protectors to provide isolation from outside interference. The slot connector has one or two open sides and is typically used for data transfer applications, where a small amount of current is necessary. The post connector has two or three closed sides and is typically used for power applications, where a large amount of current is concentrated in one area.

When it comes to the working principle of the rectangular connector, the most important factor to consider is the contact configuration. The contacts of the connector are designed to ensure that the correct amount of current is delivered to the application, while providing the necessary insulation to protect against electrical shock. The contacts also provide the necessary mechanical support to protect against accidental disconnection or damage.

In conclusion, understanding the application and working principle of the 39-01-2020 rectangular connector is vital for the successful deployment of these connectors. The various types of housings available, as well as the various contact configurations, help to ensure that the correct amount of current is delivered to the application, while providing the necessary insulation to protect against electrical shock and environmental conditions.
