Rectangular connectors are widely used in almost any application where two or more circuit boards, dash boards, components, etc need to be interconnected. The connectors are designed to allow electrical signals to travel between the two connected components securely, ensuring correct operations and minimum disruptions. It’s essential to understand the detailed working principles and variations of the many different types of rectangular connectors to ensure you choose the correct type for the application.

The 353908-3 is an example of one of many specific variations of connectors in the rectangular connection family. It is identified as a 15-pin female connector that is often used in automotive applications. Its housing design can be broken down into a few key components.

The external housing itself is made of a durable plastic material, generally using black or dark grey for this type of rectangular connection housing. On the surface of the housing, you will see 2 clear protrusions. These protrusions are used to ensure the connection between these two components is physically secured, while still allowing the connectors to be easily disconnected when necessary. The inner surface of these housings is made of a similar durable material, and includes a slight outward curve. This curve is designed to securely grip the contact posts inside the housing and ensure proper electrical connection.

The electrical contact posts, numbered from 1-15, are combined with the housing to create the full 353908-3 rectangular connector. These contact posts are spring loaded and are held inside the connector housing with a few small rubber grommets. The posts connected to pins 1-12 are single pole, while pins 13-15 are double pole. This ensures that alternate pins are available to balance the electrical load. Additionally, the contact posts are designed to be insulated, acting as a barrier between the two electrical signals.

In conclusion, the 353908-3 rectangular connector is an excellent choice for automotive applications. It contains all the essential features of a rectangular connection, while simultaneously combining these features into a consistent and reliable design. As such, it is often specified as the ideal connector for a variety of automotive applicatio0ns.
