Rectangular Connectors – Headers, Receptacles, Female Sockets are a type of connector that is designed to make reliable interconnections by providing electrical, mechanical and/or environmental isolation between circuit traces, component pads or stainless steel enclosures. ESQT-149-02-H-T-375 is a very popular rectangular connector, typically used in all kinds of electrical projects. This article aims to discuss the application field and working principle of this kind of connector.

Application Scope of ESQT-149-02-H-T-375

The ESQT-149-02-H-T-375 connector is mainly used in high-speed data transmission applications such as automotive, industrial and communications control. It has a great range of applications, such as high-speed connectivity, power requirements, signal integrity and circuit density. It is also highly effective and reliable, due to its strengthened spring-contact design. This product is also widely used in communication control, computer and intelligent peripheral circuits, such as cell phone USB connection, Wi-Fi circuit, motor control circuit, handwriting tablet, optical communication module, etc. As a result, it has wide application scenarios and is highly compatible with a variety of different connectors.

Working Principles of ESQT-149-02-H-T-375

ESQT-149-02-H-T-375 connectors use EMI circulating rings to achieve outstanding performance, which should be used when the interfaces close. By using pillars, these EMI circulating rings can effectively decrease current loop area and effectively prevent the interference of adjacent circuitry. When the interface is connected with the buffering device, the current loop area of the device can be further reduced by one half. In addition, the connector itself has two types of polarization structure - one where the terminal has two different heights, and the other where the top part of the connector is made continuous and the bottom part has discontinuity. This fixity structure is designed to ensure that when the connector is connected, the current loop area is effectively reduced and the interference is blocked.

The ESQT-149-02-H-T-375 connector has an adjustable pressure fastening system. This system adopts a back-to-back structure with two sets of pressing plates in two directions. There are two metal springs in the upper and lower plates to produce powerful pressure. This design can achieve a high-precision combination with the connector to ensure reliable contact and improve the stability of the connection.

Conclusion

In conclusion, the ESQT-149-02-H-T-375 connector is a reliable and efficient rectangular connector, well-suited for high-speed applications due to its strengthened spring-contact design and EMI circulating ring. With its two types of polarization structure, adjustable pressure fastening mechanism, and compatibility with different connectors, the ESQT-149-02-H-T-375 connector can provide excellent performance and a reliable connection in a variety of applications, such as automotive, industrial and communications control.
