Ultra-soft and burn-resistant communication cable for robot welding gun

Abstract

The invention relates to a communication cable, in particular, an ultra-soft and burn-resistant communication cable for a robot welding gun. The objective of the invention is to solve the technical problem of high possibility of fracture due to the hardness of the line core of an existing communication cable and the technical problem of a short service life of the existing communication cable due to the high possibility of damage of the sheath of the existing communication cable. According to the technical schemes of the invention, the ultra-soft and burn-resistant communication cable for the robot welding gun includes a power line and a signal line; the power line includes multi-core conductors, polyvinyl chloride insulations, a ground wire and a shielding insulation layer composed of semi-conductive non-woven fabric and a PTFE thin film, wherein the multi-core conductors, the polyvinyl chloride insulations, the ground wire and the shielding insulation layer are sequentially distributed from inside to outside; the structure of the signal line is the same as the structure of the power line; and after the power line and the signal line are subjected to cable forming, an obtained cable core is wrapped with non-woven fabric, a metal shielding layer and an insulation sheath. The cable has the advantages of super-flexibility, little possibility of core fracture, better protection shielding effects and easiness in installation. With the communication cable adopted, cost can be decreased, and production efficiency can be improved. The sheath of the communication cable has a burn-resistant property, so that the sheath will not be damaged when welding slag falls on the sheath.

Description

technical field [0001] The invention relates to a communication cable, in particular to a communication cable for a super-soft scald-resistant robot welding torch. Background technique [0002] Communication cables generally contain at least one power line and one signal line. At present, in the market, communication cables include: power core, new core, Mylar aluminum foil, outer sheath, two power lines, two signal lines Root, power line from inside to outside is tinned conductor, PVC insulation, tinned copper ground wire, Mylar aluminum foil wrapped, signal line from inside to outside is tinned conductor, foamed polyethylene insulation , The ground wire of tinned copper wire is wrapped with Mylar aluminum foil, the power line and signal line are cabled and then wrapped with thin non-woven fabric, wrapped with copper wire, and finally extruded with PVC sheath. This kind of communication cable tends to have the following problems: it is wrapped with Mylar aluminum foil, the...
