Rectangular Connectors – Headers, Receptacles, Female Sockets

The ESQT-111-02-FM-D-309 is a type of rectangular connector, specifically a female socket. These type of connectors are used for transmission signals between pieces of equipment. To understand how the ESQT-111-02-FM-D-309 works in detail, it is important to understand the structure, application fields and working principle of these types of connectors.

Structure

Rectangular connectors are composed of several metal parts, including a dielectric (protective material), contact terminals, inner sleeves, and plastic shells. The most important components of the connector are the inner sleeves and contact terminals. The contact terminals attach themselves to the wires of the device, while the inner sleeve is used to fix the contact terminals. The shells protect the contact terminals and inner sleeves from the external environment.

Application Fields

One of the main advantages of rectangular connectors is their versatility. They can be used in a variety of industries, including automotive, medical, and telecommunications. Thanks to their robust construction, rectangular connectors can handle high temperatures and vibrations, making them ideal for harsh environments. This makes them ideal for use in applications such as power supplies, computer systems, and electrical systems.

Working Principle

When in use, electricity is transferred through the connector from one device to another. The electricity travels from the metal contact terminals to the inner sleeve, where it is then passed on to the other device. This process is known as contact resistance. The dielectric material acts as an insulator, preventing electricity from passing through the connector. This ensures that the electricity stays within the connector and does not cause accidental or hazardous surges.

Conclusion

The ESQT-111-02-FM-D-309 is a type of rectangular connector that is used primarily for transmission signals between two devices. This type of connectors are composed of several components including contact terminals, inner sleeves, and a protective dielectric. They are commonly seen in a variety of industries such as automotive, medical, and telecommunications. The working principle of these connectors involves the transfer of electricity from one device to another via contact resistance.
