Signal transmission control line

Technical Field

The utility model relates to a line technical field for industrial control, in particular to line for signal transmission control.

Background

The electric appliances in the industrial control system have high requirements on the signal transmission control line, and the stability of control signal transmission needs to be ensured.

The shielding layer of the existing industrial control wire is simple, and the influence between the inner wire and the outer wire in the wire harness is reduced only through the simple aluminum foil layer and the plastic film.

The existing signal transmission control line has the following defects: the aluminum foil layer, the tinned copper braid layer and the polyester tape film layer are not used in a matched mode, the wires inside and outside the wire harness are shielded, and therefore the shielding capacity of the wire harness is limited. For this reason, we propose a line for signal transmission control.

The utility model discloses a main aim at provides signal transmission control line, can effectively solve the problem in the background art.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

signal transmission control line, including inner conductor, outer conductor and shielding layer, still include TPU layer, insulating layer and filling line, the shielding layer includes aluminium foil layer and tin-plated copper weaving layer, the insulating layer is the polypropylene layer, the filling line is the cotton thread, the inner conductor is located the polypropylene layer in, the cotton thread symmetry sets up in polypropylene layer both sides, aluminium foil layer wraps up in cotton thread and polypropylene layer periphery, tin-plated copper weaving layer cladding is in aluminium foil layer periphery.

Furthermore, the outer conducting wires are arranged between the TPU layer and the tinned copper braided layer at equal intervals.

Further, the periphery of the aluminum foil layer is coated with a polyester tape film layer.

Further, the inner lead and the outer lead are both made of tinned soft copper wires.

Furthermore, the peripheries of the inner lead and the outer lead are coated with polyethylene rubber layers through a plastic coating machine.
