CABLE WITH ELASTIC BRAIDED LAYER
FIELD
[0001] The present invention relates to the technical field of conductor
cables, in particular to a
cable with an elastic braided layer.
BACKGROUND
[0002] At present, a common cable on the market comprises an outer sheath, a
plurality of
insulating layers, a plurality of cable cores and a filler layer, wherein the
plurality of cable cores
are wrapped in the plurality of insulating layers, the whole cable is wrapped
in the outer sheath,
and the internal space of the cable is filled with fillers to form the filler
layer. However, this
kind of cables are non-elastic and non-stretchable, and are not protected from
the outside.
When applied to electronic devices, these cables cannot be freely bent or
stretched, which
indirectly restrains the movement of the electronic devices. If these cables
are repeatedly
stretched and bent in daily use, the service life of the cables will be
greatly shortened.

abreast and are
sleeved with the elastic braided layer. The elastic braided layer comprises a
left-handed braided
layer and a right-handed braided layer, and the left-handed braided layer and
the right-handed
braided layer are interlaced to form a cylindrical structure. The left-handed
braided layer
comprises first left-handed wires, second left-handed wires, third left-handed
