SQT-148-02-F-Q Application Field and Working Principle

Rectangular connectors are a type of electrical connector used to establish one or several electrical circuits between two or more devices. Headers and receptacles, along with female sockets, are vary common types of rectangular connectors. This article provides an introduction to SQT-148-02-F-Q and its application field and workings principle.

SQT-148-02-F-Q Overview

SQT-148-02-F-Qis a rectangular connector with a shrouded header and a wire-to-board receptacle. It is designed to separate pairs of signal lines. Belonging to the Tyco Electronics’SQT series, this connector has contacts with crimped wire connection,2.54 mm pitch, and 1 row(s). It has a recommended PCB hole diameter of 1.5mm, and a maximum recommended mating force of 200 N, with a retention strength of 8Kgf.

The material of the contact is copper alloy, with a 12μm tin plating on the contact area, and the material of the housing is PBT and glass filled. The temperature range where connectors can work without risk of plastic deformation, burnout or other malfunction is rated from -40Centigrade to +85Centigrade. Its voltage rating is 250V and a current rating of 6A, suitable for low voltage applications.

Application Field

Two main applications of theSQT-148-02-F-Qconnector are in LCD TV backlight and medical equipment. In LCD TVs, backlights are used to make the display visible, and they usually require an array of small connectors to provide power. In medical equipment, the connector is suitable for systems that demand good environment resistance and vibration stability. Additionally, the SQT-148-02-F-Q are also suitable for applications in security systems, lighting, and home appliances.

Working Principle

In order for SQT-148-02-F-Q connectors to work correctly, some requirements must be met. First, the cables should be correctly crimped to the contacts. Secondly, the contacts must be fully inserted into the housing. Thirdly, the lock must be engaged for a secure mating. Fourthly, the retention force should be tested after the mating o be sure that it is sufficient for the application. Finally, a pull-out force test should be done to make sure the contacts can withstand applied strain.

Before operating the connector, it is important to inspect the electrical connections correctly. This means visually checking the pins, making sure all contacts are properly seating within the connector, and that the electrical conduction pathways are correct. Furthermore, it is important to check for any physical damage and debris, to confirm the connector meets the approved performance indexes and lastly, to verify that any accessory components are properly secured.

Conclusion

The SQT-148-02-F-Q connector is a reliable and versatile electrical connector, suitable for a variety of applications in LCD TVs, medical equipment, security systems, lighting and home appliances. It is designed with features that ensure a secure connection, with good retention force and vibration stability. In order to ensure correct application, some requirements must be followed, such as correct crimping and electrical connection inspection.
