Rectangular connectors are a vital component of modern electronic systems and devices, providing reliable and robust connections with long-term performance. The SSQ-124-03-T-S-RA is a type of rectangular connector that has wide ranging applications and a unique working principle.

Application Field

The SSQ-124-03-T-S-RA connector is a 2.54mm-pitch 1x20-position straight pin header, mating with receptacle, female socket. It has a locking structure that makes it an ideal choice for those applications where vibration or contact bouncing is present. Long-term reliable connections can be made with this connector due to its rugged design, which includes a latch-lock feature that enables it to be securely connected, even under tough conditions. It is commonly used in a wide range of automotive, communications and industrial control applications.

Due to its strong and secure connection, it can also be used in high current/high voltage applications such as military and aerospace. It is frequently used in the medical field, as its connection is safe and reliable, making it suited for a wide range of medical devices.

Working Principle

The SSQ-124-03-T-S-RA connector utilizes an unambiguous and reliable lock and slide technique for mating and secure connection. Its distinct locking feature makes use of a two-out-of-three positive clicks for mating. First, slidability enables the smooth contact of the terminal and the contact pad that is present in the header. Second, the terminal itself is securely soldered to the board and hence holds the cable in rigidly. Third, a structural latch-lock button is engaged for a secure hold even when shock and vibration are present.

The 2.54mm-pitch 1×20-position pin header consists of a number of pins, each of which is individually soldered to the upstream side of the connector. A number of receptacles or female sockets contain hollow cavities that the pins are inserted into. In its engaged position, the latch-locks and the pins lock securely into the receptacle, making a strong, reliable and long-lasting connection. The pins also have a polarized feature which ensures a correct mating the first time, without the need of reconnecting. As a tertiary layer of security, two screws are included on each side of the header, locking the header in place.

Overall, the SSQ-124-03-T-S-RA connector comprises of a header, mating with receptacle, female socket, and the 3-fold locking mechanism that ensures a reliable and secure connection for long-term usage. With these features, it is clear why the SSQ-124-03-T-S-RA is an ideal choice for a wide range of applications.
