Connectors on the Move

The entertainment system provides in-vehicle options for audio and video with the ability to connect through Bluetooth, Wi-Fi, or cellular data. Any issues with the connectors would result in losing these functionalities. CONNECTOR TYPE CONSIDERATIONS D-subminiature connectors: Also known as D-Subs, these connectors have proven to be one of the most reliable types of connector. Some versions of D-Subs offer increased reliability through the ability to add other features to further secure the connection, such as retention or locking options. With many contact termination and mounting options available, D-Sub connectors are suited for high vibration applications and are available with ratings of IP67 or higher for water and dust exposure.

Plug & socket, also known as inline connectors, are perfect wire-to-wire or wire-to-board connectors for these applications, especially if the connectors have dual or double-latch technology. Dual or double-latch technology in combination with IP protection enables resistance to high vibration and provides increased retention with protection against water and dust. Having two latches increases the retention by at least 20%, enabling a better connector to reliably maintain power and data transmissions.

Terminals or contacts: Each connector has a terminal(s) assembled to transmit power, data, or signal between multiple circuits. Stamped and machined terminals are available, each offering additional features and benefits. Stamped terminals or contacts use a press machine and are less precise versus the machined contact that uses a subtractive process to ensure that exact tolerances are met. Both stamped and machined contacts are used in transportation applications.

Plug & socket or inline connectors: Many vehicles are exposed to high vibration, water, and dust and require a connector with high retention that is waterproof or rugged. In some cases, D-Sub connectors are too large and expensive for the required application, especially in miniaturized applications.
