SQT-117-01-F-D Connectors, Interconnects

Rectangular Connectors – Headers, Receptacles, Female Sockets are widely used in various areas. Among them, SQT-117-01-F-D is a kind of rectangular connectors. This article will elaborate the application and working principles of this kind of connectors.

Applications

The SQT-117-01-F-D is one of the most popular rectangular connectors – female sockets, using 100 ohm shielded twisted-pair cable with 22 to 28AWG for contact. It is designed for reliable signal transmission with cost efficient assembly and maintenance. It has strong compatibility with other connectors. SQT-117-01-F-D is popularly used in automotive industry, home appliance, communications industry and so on. In the automotive industry, it is used to connect the Ethernet cables, for communication or data exchange in workplace and home appliances. In the communications industry, it is employed where signal transmitting quality is required. The strong compatibility also makes it useful when transmitting digital signals.

Working Principle

The SQT-117-01-F-D is built with a housing body made of plastic. It consists of a main receptacle and a secondary or the "stopper" or "latches" receptor, which are designed for mounting the female contacts. The housing body includes a groove for the contact lock and an alignment ring for the cable connector. The contact lock and alignment ring help to keep the contact in position and prevent damage. The female contacts are made of brass, silver, or gold-plated metal commonly used in the telecommunications industry. The contacts consist of a spring-backed metal sleeve, plastic dielectric, and metal shield. The metal sleeve is designed to snap into the receptacle and make contact with the contact lock, and the plastic dielectric helps to keep the contact from becoming loose. The shield is designed to protect the contact from corrosion and wear.

At the female socket end of the SQT-117-01-F-D, a pair of metal springs is fitted inside each contact. These springs interact with the contact pins on the male connector plug. When a male plug is inserted, the metal springs snap out slightly against the contact pins, and a spring force holds the contact pins in place. This spring-back force deforms the contact pins slightly and helps to keep the contacts in position until the male plug is inserted. When the male plug is inserted, the spring force on the contact pins helps to make the connection more secure.

Conclusion

In a word, the SQT-117-01-F-D is a kind of popular rectangular connectors which are widely used for reliable signal transmitting. Its application is wide and it is applied to automotive, communication and home appliances. Gear with a female socket end, the SQT-117-01-F-D has a pair of metal springs fitted inside each contact so that it can interact with the contact pins on the male connector plug. The spring-back force holds contact pins in position, and the shield helps to protect the contact from corrosion.
