Abstract
The method for manufacturing a core comprises the following steps: providing a strip made of an electrically conductive material, shaping the strip into a tube, the two edges of the strip being substantially in contact, and welding together the two edges of the tube-shaped strip, via laser welding, in order to form the core (1). The method is preferably performed continuously using a continuous strip of substantial length, in an advantageous manner, the shaped and welded tube undergoes calibration, then a surface treatment intended to promote the adhesion of the insulating material (6) so as to insulate the core with respect to the external conductor (8) of the coaxial cable.
Claims16
A method for manufacturing a coaxial cable comprising forming a hollow tubular core inner conductor of the cable, at least one external surface of the core being made of an electrically conductive material, a layer of electrically insulating material surrounding the core, and an external conductor covering the layer of insulating material and electrically insulated with respect to the core,
- said method comprising the following steps:
- providing a strip made of an electrically conductive material,
- shaping the strip into a tube, the two edges of the strip being substantially in contact, and
- welding together the two edges of the tube-shaped strip, via laser welding, in order to form the core.
A coaxial cable comprising a hollow tubular core forming an inner conductor of the cable, at least one external surface of the core being made of an electrically conductive material, a layer of electrically insulating material surrounding the core, and an external conductor covering the layer of insulating material and electrically insulated with respect to the core, wherein said tubular core is formed from a strip made of an electrically conductive material and shaped into a tube, the two edges of the strip being welded together via laser welding.
