D-Sub connectors, named after their distinctive D-shaped metal shell, have a variety of contact types, ranging from a 15-pin to a 44-pin density. This type of connectors is mainly used to facilitate the connection between computer hardware, such as the connection between motherboards to display monitors or between print adapter ports on a personal computer. While the actual form factor of the connectors is invariable, the working principle, contact type, and application field can vary depending on the model.

1658612-4 is one such model. It is designed specifically as a marine-grade product, designed to be waterproof, resistant to corrosion, and reliable in high vibration applications. In terms of the connector type, it is a 19-pin male and female connectors with threaded coupling housing that can be rated up to 5 Amps. This connector type is mainly used in marine and outdoor applications, such as oil drilling platforms, telecommunication submarine cables, and power distribution stations.

In terms of working principle, the 1658612-4 model is designed to achieve two primary functions. Firstly, it provides environmental sealing, providing a barrier against dust, moisture, and other environmental contaminants in harsh conditions. Secondly, it provides mechanical locking, which ensures the stability and security of the connection even when subject to strong vibrations and other physical shocks.

In order to achieve these two features, the 1658612-4 model utilizes two components. The first is a stainless steel shell with a rubber o-ring that provides environmental sealing. The second component is a metal grommet fastened around the circumference of the connector body. This grommet provides superior tensile strength for vibration and shock resistance.

To increase the reliability of the connection even further, 1658612-4 employs contact springs with floating self-aligning pressure plates. These contacts are designed to reduce force displacement, allowing them to move freely when subject to vibrations. The self-aligning pressure plates provide superior force distribution along the contact mating surface, ensuring a reliable signal even when under extreme environmental conditions.

Overall, the 1658612-4 model is a great choice for a wide variety of marine and outdoor applications that require waterproof and vibration resistant connectors. Its robust construction ensures reliable signal transmission in tough conditions, making it an ideal choice for numerous applications.
