Rectangular connectors are nowadays widely used in electronic products and devices for its convenience in linking different parts. The SSQ-140-03-T-D-RA are headers, receptacles and female sockets which are part of the family of rectangular connectors. This article will discuss the applications and working principles of the SSQ-140-03-T-D-RA series.

The SSQ-140-03-T-D-RA seriescome with three possible contacts: receptacles, headers and female sockets. Receptacles and headers are used as plug and socket to perform a reliable, secure electrical connectivity between two separate systems. They also offer surge and EMC protection. Female sockets are through hole connections which are inserted onto PCBs to enable a physical connection to a connector mate.

The SSQ series are used for wire-to-wire and wire-to-board connections and are particularly suitable for applications in automotive, medical, audio and other high-frequency devices. Their frequently used voltage levels are automobile line (± 12V) and LINBUS (max 5V).

The advantages of SSQ series lies in its contact material, which is made of brass, the contact spring is made of phosphor bronze and the insulation material is thermoplastic PA6.6. These materials make SSQ series highly resistant to corrosion, salt-spray aging, acid and perspiration, and can be widely used in harsh environment with salt-water and air pollution.

The working principle of the SSQ-140-03-T-D-RA series is based on a unique sliding design. The center of the contact has a built-in spring to provide spring force to ensure reliable contact and mating/unmating performance. When mating, firstly the contact point is compressed, then the sliding module connects the contact point, thus ensuring reliable contact and electrical connection.

In terms of size, the SSQ-140-03-T-D-RA series support a wide range of panel thickness, from 1.0mm to 8.3mm; and board thickness from 1.6mm to 6.0mm. The size of this series includes SSQ-140-03-T-D-RA-A, SSQ-140-03-T-D-RA-B, SSQ-140-03-T-D-RA-C and so on, each of the sizes up to 7A current.

The SSQ-140-03-T-D-RA series are widely used in fields such as communication, computers, consumer electronics, controlling equipment, audio and medical equipment. It is also suitable for applications which need protection of EMC and surge.

To sum up, the SSQ-140-03-T-D-RA series are part of the family of rectangular connectors which are typically used for applications in the automotive, medical, audio and other high-frequency devices. These connectors are highly resistant to corrosion, salt-spray aging, acid and perspiration, and support a wide range of panel thickness and board thickness. Their working principle is based on a unique sliding design and the materials used allow for reliable contact and electrical connection.
