Description

A kind of shielding line

Technical field

The utility model is related to cable apparatus technical field, specially a kind of shielding line.

Background technology

Cable is the general designation of optical cable, cable and other items.The purposes of cable has a lot, is mainly used in control installation, connection and sets It is standby, the multiple action such as transmit electric power, and is common and indispensable a kind of thing in daily life.Because cable is powered, so Needs are installed especially careful.The technique class that electric wire manufacture is related to extensively, arrive by melting and pressure processing from non-ferrous metal The Chemical Engineering Technologies such as plastics, rubber, paint；The textile technology of the wrapped of fibrous material, braiding etc., to the wrapped and gold of metal material Belong to vertical bag, metal forming processing technology of welding of band etc..Existing cable is generally coaxial cable or shielded cable.Together Axis cable generally includes the electric wire surrounded by insulator, and wire rod and insulator are surrounded by shielding part, and wire rod, insulator Surrounded with shielding part by sheath.Shielded cable generally includes one or more to be surrounded by the screen layer for example formed by metal foil Insulating signal conductor.The screen layer of shielding line does not allow multipoint earthing, because different earth points is always different, each point is deposited In potential difference.Such as multipoint earthing, in screen layer formation electric current, sense and electric current is formed on wire, sense and formed on signal wire Interference, shielding action is not had not only, and interference is introduced on the contrary, especially in many occasions of frequency converter, containing each in interference Higher harmonic components are planted, are impacted more greatly, it should be specifically noted that.Shielding lines many at present when in use, are only focused on Shielding between inside and outside, the interference many times produced between Internal cable is not solved, and many cables are easily curved Lose bad, therefore devise a kind of shielding line.

Utility model content

To achieve the above object, the utility model provides following technical scheme：A kind of shielding line, including cable conductors, institute State and shielding protection layer is provided with the outside of cable conductors, in the cable conductors insertion rubber filling layer, the rubber filling layer is outer Side is provided with PET outer layers, and the rubber filling layer is provided at both ends with the elastic reinforcement muscle of elastomer braiding, the cable Conductor metal braiding layer is provided between conductor, the shielding protection layer includes being provided with the outside of PVC internal layers, the PVC internal layers PE outer layers are provided with the outside of copper wire woven screen layer, the copper wire woven screen layer.

As a kind of preferred technical scheme of the utility model, non-slip texture is provided with the outside of the PET outer layers.

As a kind of preferred technical scheme of the utility model, Reduction of Students' Study Load cavity is provided with the rubber filling layer.

As a kind of preferred technical scheme of the utility model, the elastic reinforcement muscle outer application has antioxidant coating Layer.

Compared with prior art, the beneficial effects of the utility model are：By the design of the cable conductors of internal separate type, Improve independence when signal transmission, it is to avoid cable inner is interfered during signal transmission, pass through internal set Conductor metal braiding layer improves internal shield ability, and the elastic reinforcement muscle of peripheral hardware causes cable to have more preferable toughness, is worth Promote.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belongs to the scope of the utility model protection.

Embodiment：

Fig. 1 and Fig. 2 are referred to, the utility model provides a kind of technical scheme：A kind of shielding line, including cable conductors 1, line The outside of cable conductor 1 is provided with shielding protection layer 2, the insertion rubber filling of cable conductors 1 layer 3, and the outside of rubber filling layer 3 is provided with PET outer layers 4, rubber filling layer 3 is provided at both ends between the elastic reinforcement muscle 5 of elastomer braiding, cable conductors 1 and set There is conductor metal braiding layer 6, shielding protection layer 2 includes PVC internal layers 7, and the outside of PVC internal layers 7 is provided with copper wire woven screen layer 8, The outside of copper wire woven screen layer 8 is provided with PE outer layers 9, and the outside of PET outer layers 4 is provided with non-slip texture 10, rubber filling layer 3 and set Reduction of Students' Study Load cavity 11 is equipped with, the outer application of elastic reinforcement muscle 5 has antioxidant coating layer 12.

The utility model when in use, when Internal cable conductor propagation signal, the screen set by outside Cover protective layer to keep apart inner conductor cable and external electromagnetic field, effectively avoid cable transmission signal by electromagnetic field Interference, the conductor metal braiding layer set by inside separates the electromagnetic interference of cable inner, the reinforcement that elastomer is woven into Muscle, strengthens the bending performance of cable.

The utility model improves independence when signal transmission by the design of the cable conductors of internal separate type, Cable inner is interfered when avoiding signal transmission, and the conductor metal braiding layer set by inside improves internal shield Ability, the elastic reinforcement muscle of peripheral hardware causes cable to have more preferable toughness, is worthy to be popularized.
