Product Specifications

Technical details and manufacturing context for Housing and Connector

Definition

A combined housing and connector assembly that serves as both the protective casing and the electrical interface for automotive control units (ECUs). The housing provides mechanical protection, environmental sealing, and thermal management for sensitive electronic components, while the connector facilitates reliable electrical connections to vehicle wiring harnesses and other systems. This component is designed for use in motor vehicle manufacturing, specifically for ECUs that operate in demanding conditions. The housing is typically made from engineering plastics such as PBT or PPS, or aluminum alloy, offering robustness and heat dissipation. The connector contacts are made from copper alloy, often nickel-plated for corrosion resistance. Key electrical parameters include a rated voltage of 12–24 V DC, a rated current of 10–30 A, and an operating temperature range of -40 to 85 °C. The ingress protection rating ranges from IP67 to IP69K, suitable for high-pressure washdowns. The component supports 100–500 mating cycles, with contact resistance of ≤5 mΩ initially. Dielectric withstand voltage is 500–1000 V AC. The housing material is flame retardant PA66+30%GF (UL 94 V-0), and the connector material is CuZn39Pb3 (EN 12164). Weight ranges from 50–150 g, and typical overall dimensions are 80×60×40 mm. These values are reference ranges and must be verified for the specific model and application. The component complies with relevant ISO and IEC standards as listed, but certification must be confirmed with the manufacturer.

Working Principle

The housing encloses and protects the control unit's electronic components from environmental factors such as moisture, dust, vibration, and temperature extremes. The connector provides multiple electrical contact points that mate with corresponding vehicle wiring harness connectors, enabling power delivery, signal transmission, and data communication between the control unit and other vehicle systems. The housing's design ensures proper thermal management, dissipating heat generated by the electronics. The connector's contacts are designed to maintain low resistance and withstand repeated mating cycles. The ingress protection rating ensures resistance to water and dust ingress, while the operating temperature range covers typical automotive environments. The component's materials and construction are selected to meet automotive durability requirements.
