Abstract
The signal control cable with three shields belonging to the field of cable material is wired from a plurality of wire cores constructed from copper wires and insulators. The wire cores are enwrapped by a polyster strip. A shielding layer and a protective sleeve are arranged at the out side of the cable. The shielding layer consists of two layers of braided copper wires and an aluminum-plastic composite binding which coat the shielding layer in order and separate with other by utilizing a polyster strip protection layer. A current inducting wire is arranged between the polyster strip protection layer of the second layer of braided copper wires and the aluminum-plastic composite binding. The current inducting wire tightly contacts the aluminum surface of the aluminum-plastic composite binding. The utility can be used in the fields of communication, network, data control, computer and high-new automatic equipments. Comparing with the imported equipments, the cost of the utility is just about 50% of that ones. The signals in and out the cables do not interact with each other and the utility is safe, durable, precise and has no radiation.
Description
Technical field
The utility model relates to the signal controlling cable, belongs to the CABLE MATERIALS field, refers in particular to a kind of three screens and singly protects the signal controlling cable.
Background technology
The multicore that signal controlling cable on the market constitutes copper conductors and insulator with polyester band stranding after; weave one deck copper cash again around institute's protective layer in polyester band periphery; external signal has certain phase mutual interference in the signal controlling cable of this structure; intersect mutually, influence the accuracy and the sensitivity of signal transmission.
Summary of the invention
The utility model is just in order to overcome above-mentioned deficiency; but provide a kind of internal signal complete closed; three screens that external signal also can thoroughly be got rid of singly protect the signal controlling cable; main innovation is to increase a screen; simultaneously put drainage thread at the outer shielding layer peripheral hardware; specifically implement like this: three screens singly protect the signal controlling cable; the multicore that is made of copper conductors and insulator is by polyester band stranding; external screen and the oversheath of being provided with of cable; it is characterized in that screen is two layers of copper cash braid and the plastic-aluminum combined twining package tape that the polyester band sets gradually outward; described two layers of copper cash braid; all separate between plastic-aluminum combined twining package tape with polyester band protective layer; be equipped with the metal drainage thread between the copper cash braiding polyester band protective layer of the second layer and plastic-aluminum combined twining package tape, described metal drainage thread is close to the aluminium face of aluminium-plastic tape.By three layers of shielding, between each screen with do not absorb water, electrically non-conductive material separates, can avoid blurring, can not only be with the internal signal complete closed, be not subjected to external interference, even there is extraneous signal can interference signal thoroughly be got rid of, device security, reliably, accurately do not have any radiation by drainage thread yet.
This practical described copper conductors is a tin annealed copper wire, makes insulator with PVC or other resin material, carries out twice braiding with tin annealed copper wire behind the multicore stranding, and count is at 85-90%.The metal drainage thread selects for use tinned copper wire to arrange.
The utility model uses aspect communication, network, Data Control, computer and high-new automation equipment, compare import and produce this reduction about 50%, the interior external signal complete closed of cable, cross influence not mutually, reliably, does not accurately have any radiation at entire equipment safety.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Three screens singly protect the signal controlling cable; the multicore that is made of tin annealed copper wire conductor 1 and insulator 2 is by polyester band 3 strandings; external three layers of screen and the oversheath 7 of being provided with of cable; polyester band 3 three layers of outer screen are two layers of tin annealed copper wire braid 4 and plastic-aluminum combined twining package tape 5 successively; the count of tin annealed copper wire braid 4 is at 85-90%; two layers of tin annealed copper wire braid 4; 5 of plastic-aluminum combined twining package tapes all separate with polyester band 3 protective layers; copper cash braiding polyester band 3 protective layers and 5 of the plastic-aluminum combined twining package tapes of the second layer are equipped with tinned copper wire drainage thread 6; drainage thread 6 is close to the aluminium face of aluminium-plastic tape 5; according to different operational environments, insulating barrier 2 and oversheath 7 can be selected PVC or other resin material.
