The ESQT-130-02-G-Q-385 is a type of rectangular connector, part of a range of rectangular connectors which include headers, receptacles, and female sockets. Originally used within the automotive world, these connectors are now employed in a wide range of applications, particularly those requiring a reliable interconnect between circuits. This article aims to provide a detailed overview of the application fields and working principle of the ESQT-130-02-G-Q-385.

Application Fields

The ESQT-130-02-G-Q-385 is a smallest connector, designed for use in space-constrained applications. This connection option, which conforms to MIL-C-38999/1 specifications, is primarily used to interconnect various electronic circuits in a variety of industries. These include aerospace, automotive, medical, and marine, among many others.

In aerospace applications, for instance, the ESQT-130-02-G-Q-385 may be used to connect PCB components into a complicated avionic system. In automobiles, the connector can be used to join parts of the chassis, taking into account the harsh temperatures and vibration experienced on the road. It is a reliable interconnection option in such scenarios, as it is rated for high shock and vibration resistance.

Working Principle

The ESQT-130-02-G-Q-385 is composed of two elements, a header and a receptacle, which are mated together to form a reliable interconnect between two electrical circuits. The header part has a series of electrical contacts that, when connected to a power source, transmit power to the receptacle. The receptacle in turn has a number of electrical contacts which receive the transmitted power and are used to power other circuits.

To ensure a secure connection, the header fitting has a series of screws that provide mechanical strength and reduce electrical noise. Additionally, the receptacle has a series of spring clips which keep the connectors securely locked in place when two components are mated. This combination provides a reliable electrical connection between two circuits even in the presence of mechanical vibration and shocks.

The working principle of the ESQT-130-02-G-Q-385 also ensures that it can be safely removed from a circuit without causing any damage. It is designed with a quick-release mechanism that allows for a controlled disconnection. The spring clips can easily be pushed apart with a pinor small screwdriver, releasing the two parts of the connector and permitting a secure removal without conducting any harmful voltage or current.

Conclusion

The ESQT-130-02-G-Q-385 is a rectangular connector, typically used as a reliable interconnect between two electronic circuits in a variety of industries such as aerospace, automotive, and medical. Its working principle involves a header and a receptacle, which are mated together securely through a combination of screws and spring clips. This combination provides reliable electrical connections between two circuits and makes it easy to disconnect the connector without harm.
