FIELD: electricity.SUBSTANCE: sealing designed mostly to reduce interference from electronic noise and radio frequency interference (EMI/RFI) consists of seal housing that has circular cavity and ring spring inside circular cavity. Seal housing includes composite material that contains thermoplastic material and filler. Composite material can have Young's elastic modulus at least approximately equal to 0.5 GPa, bulk resistivity less than approximately 200 Ohm·cm, modulus of elongation at least approximately equal to 20%, surface resistivity less than approximately 10Ohm/square or their any combination.EFFECT: increasing operational reliability of electronic systems due to controllability and capability to reduce EMI preventing operation of electronic system.16 cl, 7 dwg, 1 tbl |
