Patent ID: 8586868

Claim:
A cable comprising: a conductor keeper made of plastic, being elongated and having two end surfaces; an annular surface; and multiple grooves formed longitudinally in the annular surface of the conductor keeper and formed through two end surfaces of the conductor keeper; multiple bare conductors made of metal, each bare conductor mounted in one of the grooves of the conductor keeper and having a first end and a second end and the first end and second end of the bare conductor protruding out of the two end surfaces of the conductor keeper respectively so as to form two spaces between the first ends and second ends of the bare conductors; a dielectric tape wrapped around the annular surface of the conductor keeper; a plastic jacket coated around the dielectric tape; and two copper cylinders mounted in the spaces of the bare conductors respectively to make the bare conductors surround the copper cylinders and the bare conductors connect to each other in parallel; wherein each copper cylinder has two end surfaces; an annular surface; and multiple recesses formed longitudinally in the annular surface of the copper cylinder, formed through two end surfaces of the copper cylinder, aligning respectively with the grooves of the conductor keeper and holding respectively the ends of the bare conductors inside; and wherein each bare conductor is circular in cross section and has a radian corresponding to a radian of the corresponding groove of the conductor keeper.
