The utility model discloses be applied to the technical field of cable.
Description
Technical Field
The utility model discloses be applied to the technical field of cable, in particular to soft fire-retardant low noise coaxial cable.
Background
Traditional coaxial cable is by inner conductor, polyethylene insulating layer, outer conductor shielding layer and material sheath, and wherein outer conductor shielding layer is woven by the copper wire and is formed on the plastic-aluminum composite strip, and the overall structure that leads to the cable is harder, and the compliance is lower, and bend radius is little, can't be applicable to the corner installation, leads to the construction comparatively difficult, and tensile ability is weak simultaneously. In addition, the flame retardant effect is general and noise is generated in the process of transmitting signals, and the noise is increased along with the increase of the transmission frequency, so that the receiving effect of the terminal equipment is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome prior art not enough, provide a tensile ability well and have good interference killing feature's soft fire-retardant low noise coaxial cable.
The utility model adopts the technical proposal that: the utility model discloses a copper core, insulating layer, outer conductor shielding layer and the sheath that sets gradually from inside to outside, the insulating layer with be provided with polytetrafluoroethylene semiconduction band layer between the outer conductor shielding layer.
According to the scheme, the polytetrafluoroethylene semi-conductive tape layer has excellent flexibility and toughness, so that the coaxial cable has better tensile capacity; meanwhile, the polytetrafluoroethylene semi-conductive tape layer is arranged to absorb and isolate high-frequency noise, so that the noise in signals is effectively reduced; meanwhile, the polytetrafluoroethylene semi-conductive belt is a non-combustible material, so that the cable can be effectively prevented from burning.
Preferably, the sheath is a flexible flame-retardant polyvinyl chloride layer.
According to the scheme, the flexibility and the flame-retardant effect of the cable are further enhanced by adopting the flexible flame-retardant polyvinyl chloride layer as the sheath.
Preferably, the outer conductor shielding layer is formed by weaving copper wires.
According to the scheme, the outer conductor shielding layer formed by weaving copper wires is used for primary noise shielding, and is matched with the polytetrafluoroethylene semi-conductive tape layer to effectively reduce the influence of external signals and increase the bending performance.
