Preferably, the outer protective sleeve is sheath made by polythene material, and/or the screen layer is covered with height for surface The magnesium alloy plate of polymeric layer.

Preferably, the insulating barrier is the macromolecular material layer of insulation, and/or the sealing coat is high polymer Layer.

Conceived based on same aspect, this utility model has been also provided to a kind of cable connector, and it includes tab terminal, should Tab terminal has the installing hole for installing described cable, and the inwall of the installing hole is provided with graphene layer, the graphene layer Contact for the internal layer cored wire conductor with the cable.

Preferably, the installing hole is blind hole.

The tab terminal is light-weight metal joint.Further, the tab terminal is aluminum alloy joint.

It is to be removed cable socket outer insulator to be connected with wire stripper that cable connector of the present utility model makes, will be interior Layer cored wire conductor insertion tab terminal straight tube ring pinching end inwall, and suppressed by clamp specially, fix cable and terminal.

Compared with prior art, the beneficial effects of the utility model are：Cable of the present utility model and its joint not only may be used To fully meet Quick conductive requirement, various bending environment are adapted to, while relative to the cable and its joint of metal structure, its is heavy Amount can reduce more than 85%, greatly reduce weight in working order, improve cable service life.
