Space-saving connector system targets car interior

January 28, 2014 // By Christoph Hammerschmidt
The Mini50 is an unsealed wire-to-board connector system, and according to vendor Molex, it is the smallest automotive-grade one on the world market. For automotive electronics designers it certainly is relevant that the US Council for Automotive Research (USCAR) has approved this connector system.

USCAR supports cooperative research and development to advance automotive technologies. The Mini50 USCAR 050 approved interface delivers 50% space savings over traditional USCAR 0.64mm connectors, with smaller terminals to fit more low-current electrical circuits in interior, unsealed transportation-vehicle environments. The compact connectors are designed for use in applications where space is limited, such as lighting, radios, navigation systems, HVAC systems, mirrors and cameras. They provide reduced overall harness weight savings by allowing wire-harness customers to crimp and process smaller wire gauges versus traditional 0.64mm terminal systems.

The system features an independent secondary lock (ISL) that is part of the housing, reducing the number of components. In addition, PCB headers are released in both vertical or right angle orientations to provide wire-routing and module design flexibility. They are also constructed with a high-temperature thermoplastic housing that withstands infrared (IR) and wave lead-free solder processing at temperature of up to 260ºC.
