Board-to-Wire Connectors for Automotive Infotainment Systems

LD20/SP20 Heavy-Duty Square Connector

Project Background

Automotive infotainment systems in Japan integrate displays, control units, and multimedia interfaces within the vehicle dashboard. These systems require compact internal connections to support data transmission and power distribution. The growing complexity of in-vehicle electronics in the Japanese automotive market demands reliable board-to-wire interconnection solutions that fit within space-constrained dashboard layouts.

Application Requirements

Board-to-wire connectors are used inside infotainment units to connect printed circuit boards (PCBs) with cable assemblies. Typical applications include:

• Display module connections
• Internal signal routing between boards and interfaces
• Control panel wiring

These connections support both power distribution and low-voltage signal transmission within the infotainment unit, enabling communication between the main board, display driver, and user interface controls.

Solution and Design Fit

These connectors are designed for compact layouts, allowing multiple connections within limited space. The low-profile housing and fine-pitch contact arrangement help engineers optimize PCB real estate while maintaining secure wire retention. They are typically used in protected environments inside the dashboard, where exposure to moisture and contaminants is limited.

Commissioning and Operational Performance

Within vehicle interiors, connectors are exposed to moderate vibration and temperature changes. Board-to-wire connectors provide stable electrical connections when properly secured. For infotainment applications, consistent contact pressure and reliable terminal locking are essential to maintain signal integrity over the vehicle's service life. Proper wire strain relief and correct mating alignment further support long-term performance in daily driving conditions.

Result and Selection Guidance

In automotive infotainment systems, board-to-wire connectors support compact design and reliable internal connectivity. For engineers evaluating interconnection options for dashboard electronics, selecting a connector with appropriate pitch, current rating, and locking mechanism is critical to meeting both assembly and operational requirements.
