Component Specifications

Definition
The outer shell is a critical structural component of high-frequency RF coaxial connectors that encloses and protects internal dielectric and conductor assemblies. It provides electromagnetic interference (EMI) shielding, mechanical stability, environmental sealing against moisture and contaminants, and proper mating interface alignment. Manufactured with precision tolerances to maintain consistent impedance and signal transmission characteristics across GHz frequency ranges.
Working Principle
Functions as the primary mechanical and electromagnetic enclosure that maintains the coaxial structure's geometry, provides grounding continuity through its conductive material, and ensures proper shielding effectiveness by creating a continuous Faraday cage around the signal path. The shell's dimensional precision maintains the required impedance matching between connector interfaces.
Materials
Beryllium copper (BeCu) alloy with gold or silver plating for optimal conductivity and corrosion resistance; alternative materials include brass with nickel plating or stainless steel for harsh environments. Dielectric inserts typically use PTFE (Teflon) or other low-loss polymers.
Technical Parameters
  • VSWR <1.3:1 typical
  • IP Rating IP67 when mated
  • Impedance 50 Ω standard (75 Ω available)
  • Mating Cycles >500 cycles
  • Frequency Range DC to 40 GHz
  • Operating Temperature -55°C to +125°C
  • Shielding Effectiveness >90 dB at 1 GHz
Standards
IEC 61169, MIL-PRF-39012, DIN 47223
