Shielding Component
Mechanical interconnect component used to provide a continuous conductive path between a cable shield and a connector housing. The 360 degree crimp ferrule establishes a uniform radial compression that maintains electrical bonding across the entire circumference. This design prevents electromagnetic interference leaks that occur when gaps exist in the termination.
Crimp Integrity
Radial deformation of the metal sleeve ensures gas-tight contact with the braided or foil shield. The 360 degree crimp ferrule requires a specific die set sized to the cable outer diameter to prevent over-compression or loose fits. Precise geometry in the tool allows the metal to flow into the shield interstices without severing individual strands.
Electromagnetic Performance
Shielding effectiveness depends on the low-impedance connection provided by the peripheral contact. While pigtail terminations introduce inductive loops, the 360 degree crimp ferrule minimizes inductance and supports high-frequency signal integrity. Testing often involves measuring transfer impedance across a wide frequency range to verify the seal against external noise (typically from kilohertz to several gigahertz).
Signal attenuation remains stable under vibration due to the symmetrical distribution of mechanical stress.
Installation Constraint
Material hardness and wall thickness of the sleeve dictate the required crimp force. Because 360 degree crimp ferrule applications involve specialized tooling, field repairs become difficult without identical hardware. Proper stripping of the outer jacket is a prerequisite for a valid termination.
