Technical details and manufacturing context for Cap/Lid Assembly

Definition

The Cap/Lid Assembly is a critical component of the Cell Housing Assembly that provides hermetic sealing, environmental protection, and structural integrity for the enclosed cell components. It typically includes the main lid, sealing gaskets, fastening mechanisms, and electrical feedthroughs where applicable. The assembly is designed to fit a range of cell housing openings, with a sealing diameter from 18 to 120 mm and an overall height from 5 to 30 mm. It is manufactured from materials such as aluminum alloy (grade Al 6061-T6), stainless steel, and silicone rubber, offering corrosion resistance and lightweight properties. The assembly operates under a working pressure of 1.0–1.6 MPa, within a temperature range of -40 to 85 °C, and provides ingress protection rated IP54 to IP65 (per IEC 60529). Key dimensional and surface parameters include flatness of ≤0.05 mm (per ISO 1101) and surface roughness of Ra 0.8–1.6 µm (per ISO 4287). Electrical safety is ensured with insulation resistance of ≥100 MΩ at 500 V DC and dielectric withstand voltage of ≥500 V AC for 1 minute (per IEC 60243-1). The assembly weight ranges from 5 to 50 g. These values are reference ranges for directory purposes; actual specifications must be confirmed with the legal manufacturer or supplier for the specific model and application. The assembly is intended for use in computer, electronic, and optical product manufacturing, serving as a component in cell housing assemblies. It is not a standalone product but a part that requires integration into a larger system. The directory does not manufacture or sell this product; it provides neutral information for procurement and verification. Always verify model-specific values and standards with the legal manufacturer or supplier before use.

Working Principle

The assembly creates a sealed enclosure by applying compression force through fasteners onto sealing materials, preventing ingress of contaminants while maintaining structural stability and electrical isolation as required. The sealing gaskets, typically made of silicone rubber, deform under compression to fill gaps between the lid and the housing, ensuring a hermetic seal. The fastening mechanisms, such as screws or clamps, provide the necessary clamping force. The electrical feedthroughs, if present, allow for electrical connections while maintaining the seal. The design ensures that the operating pressure and temperature ranges are maintained, and the ingress protection rating is achieved. The flatness and surface roughness of the sealing surfaces are critical to ensure uniform sealing pressure and prevent leaks. The assembly must be installed correctly to achieve the specified performance; improper installation can lead to seal failure and loss of protection.
