Abstract

The utility model discloses a thermocouple compensation cable, which comprises a plurality of inner core conductor wires, wherein a first PVC (Polyvinyl Chloride) insulation layer is wrapped on the surface of each inner core conductor wire; a first Mylar layer, a metal net type shielding layer and a second Mylar layer are wrapped outside a plurality of inner conductors in turn; a plurality of outer core conductor wires are uniformly distributed on the outer circumference of the second Mylar layer; a second PVC insulation layer is wrapped outside the outer core conductor wires; a non-woven fabric layer is wrapped outside the plurality of outer core conductor wires; and a third PVC insulation layer is wrapped outside the non-woven fabric layer. According to the utility model, a filling material is filled in a gap between conductor cores, so that roundness, hand feel and attractive appearance of the cable disclosed by the utility model can be increased; the whole cable can be effectively shielded by using a copper net woven layer, so that external interference is reduced; the conductor core disclosed by the utility model is wound by the layer of non-woven fabric, so that the cable is easier and more convenient to peel; and the thermocouple compensation cable is applied to the equipment such as thermocouples.

Description

A kind of thermocouple compensating cable

Technical field

The utility model relates to lead, is specifically related to a kind of thermocouple compensating cable.

Background technology

In the prior art, the thermocouple compensating cable has advantages of good shielding performance, can reduce external interference; Strong anti-interference performance ensures the requirement of data quality.

The utility model content

The purpose of the utility model is that the above-mentioned defective to prior art provides a kind of strong anti-interference performance, ensures the thermocouple compensating cable of data quality.

Construct a kind of thermocouple compensating cable, comprise many inner core leads, the surface of every inner core lead is surrounded by a PVC insulating barrier, and the outside of many inner wires is surrounded by successively: first wheat draws layer, metal net shaped screen, second wheat to draw layer; Second wheat is drawn on the excircle of layer and is evenly equipped with many outer core leads, is surrounded by the 2nd PVC insulating barrier outside the outer core lead, and the outside of many outer core leads is surrounded by nonwoven layer, and the outside of nonwoven layer is surrounded by the 3rd PVC insulating barrier.

In above-mentioned thermocouple compensating cable, be provided with 6 pairs of inner core leads altogether, 12 outer core leads.

The thermocouple compensating cable that the utility model provides, thermocouple compensating cable comprise plurality of conductors (copper-nickel alloy, iron wire, pure naked copper), insulating barrier, filler, copper wire mesh braided layer, restrictive coating; The utility model thermocouple compensating cable crust has adopted low-gravity, material wear-resisting, flame-proof polyvinyl chloride to process, and can guarantee the safe operation of cable performance.In addition and since first copper wire mesh braided layer weave again after having increased wheat and drawing copper mesh again Bao Maila twine, it can make carries out careful buffer action between core and the copper mesh, it is unusual can not produce bad electrical property such as short circuit.Be filled with filler in the space between the core of the utility model, the cable that can strengthen the utility model has circularity preferably, increases feel and attractive in appearance.The copper wire mesh braided layer that the utility model uses can effectively shield whole cable, thereby reduces external interference.The utility model core bag one deck do not have anti-cloth and twine, can make the cable processing of peeling more easily, more easily.Be applicable to equipment such as thermocouple.
