ESQT-149-02-L-Q-450 application field and working principle

The ESQT-149-02-L-Q-450 Rectangular Connector belongs to a family of Rectangular Connectors, which are electrical connectors that join electrical cables or wires together. It falls into one of the sub-families – Headers, Receptacles, Female Sockets. Its key features are the two fingers at the end which help to hold onto the mated part.

This family of rectangular connectors comes in a wide range of sizes, including 2.54 mm (0.1 inch) and 6.35 mm (0.25 inch) grid sizes. The length and width of the body, the number and positions of the pins, and the type of fastener are the main variables when it comes to deciding which rectangular connector is the right one to use for the job.

Application field

This family of rectangular connectors is widely used in various types of electronic equipment and in computer and telecommunications applications. They are used to connect boards, cables, and devices, and provide a secure and reliable connection. These connectors can be used in harsh environments, in extreme temperatures, and in locations exposed to dust, vibration, or shock.

Working Principle

The ESQT-149-02-L-Q-450 rectangular connector consists of two parts that connect together, the header and the receptacle. The header contains the electrical contacts which connect to the mating receptacle. The receptacle contains a series of female sockets into which the header pins are inserted. The header is connected to the device or cable and the receptacle is connected to the mounting board, thus, forming a secure electrical connection.

The header and receptacle of the rectangular connector are fitted with a fastener which securely locks the two components together. This fastener may be a screw or a latch. The screw-locking type of fastener ensures a tight connection and reduces the risk of loosening due to vibration or shock. The latch-locking type of fastener is simple to operate and does not require a tool to be used.

The ESQT-149-02-L-Q-450 rectangular connector is designed for robust and reliable performance and is suitable for use in a range of applications, from telecoms and industrial to medical applications and consumer electronics. It also meets the requirements of UL94-V0, which is a flammability rating standard and indicates that is suitable for use in an environment with high fire or explosion risk.

Conclusion

The ESQT-149-02-L-Q-450 Rectangular Connector belongs to the family of rectangular connectors – headers, receptacles, and female sockets. These connectors are widely used in various types of electronic equipment and serve the purpose of joining electronic boards, cables, and devices securely. The two parts of the connector, the header and the receptacle, are fitted with a fastener which securely locks them together. This fastener can be either a screw or a latch, and the connector also meets the UL94-V0 flammability rating standard.
