Description
Technical field
The utility model relates to a kind of cable, particularly relates to a kind of cable with signal transmission effect.
Background technology
Along with the development of electronics technology product is popularized, cable is as a kind of instrument of signal transmission, multiple actions such as there is Signal transmissions, control installation, connection device, transmit electric power, it is common and indispensable a kind of thing in daily life, cable Prolonged exposure in atmosphere, be easy to make moist, therefore need it to possess waterproof and dampproof function.And if breaking out of fire, cable can become very soon propagates the medium of fire, and this just needs overhead cable to have anti-flaming function.Cable needs the well work of shielding interference ability, but, uvioresistant, fire-retardant and shielding interference these functions being not easy will be reached simultaneously, and cable is in transmitting procedure, cable core is easily squeezed, cable core mutually extrudes and also makes cable cause signal attenuation in data transmission procedure, have impact on the transmission rate of data.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provides a kind of signal cable, has uvioresistant, protection against the tide, fire-retardant, shielding interference, the function that prevents cable core to be squeezed, thus ensures its useful life.
The technical solution of the utility model is: a kind of signal cable, comprises steel core, insulating case tube layer, metal screen layer, flame-retardant layer, uvioresistant plastic sheath.Four pieces of demarcation strips are comprised in insulating case tube layer, a steel core is provided with in the middle of cable, steel core is positioned at the square formed in the middle of four pieces of demarcation strips, each side of four pieces of demarcation strips is mutually permanently connected, insulating sleeve inside is divided into four parts by four pieces of demarcation strips, in insulating sleeve, there is filler, form closely sturdy support.
Further, described metal screen layer is for transmitting negative electricity.
Further, described steel core to be wrapped in around steel core by stranded mode by aluminum steel and steel wire and to form.
Further, the consistency of thickness of described insulated conduit layer, uvioresistant plastic material layer and flame-retardant layer.
Further, the material of described uvioresistant plastic sheath is polyvinyl chloride, and in oversheath, back-up coat is polyethylene.
Further, described cable core is respectively equipped with three bars heart yearns, and the external diameter of every bars cable is identical.
Further, comparatively signal core line is thick for described power supply heart yearn.
Further, described filler material is cotton.
Further, the specification of described power supply heart yearn is 35AWG, and the specification of described signal core line is 30AWG.
Further, described signal core line is used for differential signal transmission, described power supply heart yearn transmission+16V voltage
The beneficial effects of the utility model are: a kind of signal cable, and wherein in cable core, steel core to be wrapped in around steel core by stranded mode by aluminum steel and steel wire to form, and steel core mainly plays the effect of gaining in strength, and aluminum steel mainly plays a part to transmit electric energy.Uvioresistant oversheath can resist ultraviolet to a certain extent, is provided with back-up coat in oversheath, and cable can be protected inner when oversheath is damaged, screen can shield interference signal, ensures the normal work of cable.Flame-retardant layer can be fire-retardant to a certain extent, prevents cable from becoming the medium of fire-propagation, and the utility model is provided with four pieces of dividing plates in inside, dividing plate is positioned at insulating case tube layer, and dividing plate material is polyamide, and polyamide has excellent mechanical property, mechanical strength is high, good toughness, has excellent thermal endurance, heat distortion temperature is very high, can at high temperature the long-term phase use, polyamide also has excellent electrical insulation capability, and volume resistance is very high, can breakdown voltage resistant height, be excellent insulating material.A steel core is provided with in the middle of cable, steel core is positioned at the square formed in the middle of four pieces of demarcation strips, each side of four pieces of demarcation strips is mutually permanently connected, insulating sleeve inside is divided into four parts by four pieces of demarcation strips, in dividing plate, there is filler, filler material is cotton, form closely sturdy support, avoid the phenomenon causing flattening when complications, this cable can prevent mutual interference, can not production cost be increased considerably again and its rounding property can be ensured, have fire-retardant, uvioresistant, inner firmly, advantage that mechanical strength is large.
