Application Field

Rectangular Connectors - Headers, Receptacles, Female Sockets are used to facilitate electrical connections. The SQT-110-01-F-D-RA-002 defined narrow pitch terminals, housing and plugs which enable efficient interconnectivity.This connector specifically has been designed for use in instrumentation, car radio, LCD and I/O production for all kinds of electronic products, where space is limited and reliability is a prerequisite. It is extensively used in the fields of medical device, wire connector, printer, and so on.

Working Principle

The principle of the SQT-110-01-F-D-RA-002 rectangular connector lies in its connector design which provides a secure mating of two electrical devices, allowing for minimal power losses.The connector is composed of a metallic body (or shell) with multiple terminals and two removable mating surfaces (or plugs for male and female). The metal body is generally designed to reduce electromagnetic interference (EMI)induced by unsolicited induction and to provide strain relief of coax cables.The plug gap ensures reliable contact upon snap-fit insertion of the plug into the socket, thus providing a tight grip when locked in. There is also a certain gap between the innerwall of the shell and the plug sleeve so that contact is not made during insertion. This feature eliminates short circuiting and is especially important where electrical power is present.The socket contact system can be designed as a separate stand-alone system, also known as a bed-of-nails, or made in conjunction with a solder tail for reliable connection to a printed circuit board (PCB). The two contact systems further incorporate integrated stabilizing elements (such as levers) which adjust and maintain the connection between the contacts when the plug and socket are mated. The connection between the plugs or sockets is achieved through the metal body, thus the connection is inspired by a \'line-to-line\' configuration, where two electrical lines are orthogonally connected.

Conclusion

The SQT-110-01-F-D-RA-002 rectangular connector is an ideal solution for applications requiring a secure electrical connection with minimal space requirement. The snap-fit insertion of the plug to the socket, the integrated stabilizing elements and the insulation sleeve around the plug ensure a reliably operating connection. It is suitable for instrumentation, car radio, LCD, medical device, wire connector, printer, and other electronic product applications.
