Abstract

The utility model discloses a movable flexible flat cable, which comprises three conductors. A tin layer is plated on the outer wall of each conductor. An insulating layer and a taping layer are sequentially wrapped outside each conductor. A fireproof layer is wrapped outside each taping layer, and is formed by overlapping and lapping a plurality of layers of heat-resistant polyester thin film strips, and a lapping and overlapping rate is not lower than 56 percent. A reinforcement layer is wrapped outside each fireproof layer. Elastic bodies formed by extrusion-molding silicone rubber are arranged between every two of a plurality of conductors with the reinforcement layers. Each elastic body has a quadrangular section of which a side attached to a corresponding reinforcement layer is inwards sunken. A flat sheath layer is extrusion-molded outside the elastic bodies and the conductors with the reinforcement layers. The movable flexible flat cable is rational in structural design; the elastic bodies are arranged between the reinforcement layers of every two conductors of the cable, so that the resistance of the cable to tension and external transverse pressure is effectively enhanced; the sheath layer is manufactured by extruding butyronitrile-polyvinyl chloride composite flame-retardant elastic body, and has strong warping strength; and in addition, the cable has high fireproof performance and long service life.

Description

The flat flexible cable of a kind of mobile model

Technical field:

The utility model relates to the power cable field, relates in particular to the flat flexible cable of a kind of mobile model.

Background technology:

The cable that moves usefulness is operated under the condition of high temperature, because the production environment temperature is high, and the cable insulation easy ageing; Reduced the useful life of cable design, improved cable and changed frequency, in the production; Cable running time under the time limit of normally using according to cable design in cable useful life and the varying environment, definite according to experience, for fear of the cable accident of bursting apart; Increase coefficient of safety, cable value in useful life is less, and the replacement cycle is short.Because power set need a large amount of power cable and control cable, it is very high to change frequency, and changing the power set cable needs great amount of manpower; Thereby shorten the replacement cycle operation, and increased cable cost, wasted manpower; Increase the maintenance off-time, reduced production efficiency.

Too early bending failure of conductor and fracture just took place in one month in have even less than, how to improve anti-song property level, stretch-proof performance, the anti-cross force extrusion performance of such cable, and how carrying out material chosen and architecture advances is the emphasis of industry work.

The utility model content:

To the prior art problem; The purpose of the utility model provides the flat flexible cable of a kind of mobile model; Be applicable to frequent move, the electric power transfer of be used as power under the occasion of oil resistant device or portable lighting, construction of cable compactness, stretch-proof performance, anti-song property level, anti-cross force extrusion performance are superior.

The technical scheme of the utility model is following:

The flat flexible cable of mobile model comprises that three outer walls are coated with the conductor of tin layer, and the conductor outside is enclosed with insulating barrier, belting layer respectively successively; It is characterized in that: described belting layer is wrapped with fireprotection layer; Fireprotection layer adopts the several layers of overlapping wrapped formation of high temperature resistance polyester film band, and wrapped Duplication is not less than 56%, and described fireprotection layer is wrapped with reinforced layer; Be provided with the elastomer of silicon rubber extrusion moulding between several conductors of parcel reinforced layer; Described elastomer cross section is a quadrangle, and the limit that quadrangle and described reinforced layer fit caves inward, and the outer extrusion moulding of conductor of described elastomer and parcel reinforced layer has the restrictive coating of flat.

The flat flexible cable of described mobile model is characterized in that: described restrictive coating adopts expressing technique to adopt squash type, and material is adopted as butyronitrile polyvinyl chloride composite flame-proof elastomer.

The utility model has the advantages that:

The utility model reasonable in design; Between the reinforced layer of cable conductor, be provided with elastomer, strengthened the stretch-proof performance of cable and the performance of anti-extraneous transverse pressure effectively, restrictive coating adopts butyronitrile polyvinyl chloride composite flame-proof elastomer to extrude and processes; Anti-Qu Xingneng is stronger; In addition, fireproofing of cable better performances, long service life.

Fig. 1 is the structural representation of the utility model.

Embodiment:

The flat flexible cable of mobile model comprises that three outer walls are coated with the conductor 1 of tin layer, and conductor 1 outside is enclosed with insulating barrier 2, belting layer 3 respectively successively; Belting layer 3 is wrapped with fireprotection layer 4; Fireprotection layer 4 adopts the several layers of overlapping wrapped formation of high temperature resistance polyester film band, and wrapped Duplication is not less than 56%, has improved fireproofing of cable performance and resistance to elevated temperatures; Fireprotection layer 4 is wrapped with reinforced layer 5; Be provided with the elastomer 6 that the silicon rubber extrusion moulding constitutes between the conductor of parcel reinforced layer 5, elastomer 6 cross sections are quadrangle, and the limit that quadrangle and described reinforced layer fit caves inward; Strengthened the stretch-proof performance of cable and the performance of anti-extraneous transverse pressure effectively, the conductor 1 outer extrusion moulding of elastomer 6 and parcel reinforced layer 5 has the restrictive coating 7 of flat.

Restrictive coating 7 adopts expressing technique to adopt squash type, and material is adopted as butyronitrile polyvinyl chloride composite flame-proof elastomer.
