Rectangular Connectors - Headers, Receptacles, Female Sockets

The ESQT-140-02-G-T-431 is a rectangular connector that is commonly used in assembly processes. While the exact parameters of the product may vary, usually such a product is made of plastic and includes a receptacle (housing) containing two or more pins. These pins are generally used to allow an electrical current to pass between two separate boards, or between two electronics components. Additionally, some variations of this product include headers for additional support and connection.

Application Field

The application field of rectangular connectors, including the ESQT-140-02-G-T-431, extends through several industries. Automotive, aerospace and defense, industrial, medical, and consumer industries are some of the main areas where the use of this type of connector can be found. It is also commonly used in communications, transportation, and digital electronics technology.

Within the automotive sector, rectangular connectors are generally used for power and signal functions. In aerospace and defense, they are usually used to control aircraft systems, as well as for the construction of microprocessors and weapons components. In industrial and manufacturing systems, they can be used to carry power throughout wiring projects, manage signals between machines, and secure cables to boards. Medical companies make use of them in order to connect electrical components within medical devices. And finally, consumer industries employ the use of these connectors to design and manufacture electronic products.

Working Principle

The working principle of rectangular connectors is quite simple. The product especially the ESQT-140-02-G-T-431 consists of two parts: a receptacle, which stays fixed, and a header, which can be inserted into the receptacle to effect a connection between the two. As the name suggests, the receptacle is the housing which contains two or more pins, or “contacts,” that are connected to a printed circuit board. The header acts as the “isplug” that enables the application of power to the pins in the receptacle, thus establishing a connection between two pieces of hardware.

To make the connection, the connector is inserted into the receptacle by force. As the pins on the header make contact with the contacts in the receptacle, the electrical current flows, making the connection and allowing the device to function properly. When the device is powered down, the connection is broken and the power is no longer applied. Additionally, in some cases the connections between the two may be secured with screws, although this is not always necessary.

Sometimes, for further connection security, rectangular connectors may include two clips. These clips latched to the header and/or the receptacle, further ensuring that the device remains connected until the power is turned off. Additionally, they provide additional stability to the connection by preventing the header from being disconnected easily.

Conclusion

The ESQT-140-02-G-T-431 rectangular connector is an example of a common electronic connector that is used in a wide variety of industries. It consists of a receptacle containing two or more pins, which are connected to a printed circuit board, and a header, which is inserted into the receptacle to create an electrical connection. The working principle behind these types of connectors is quite simple, as the header connects to the receptacle to apply power and secure the connection. In some cases, clips may be included for added connection security. This type of connector is very useful in many industries, such as automotive, aerospace, and defense, industrial manufacturing, medical, and consumer electronics.
