Abstract
The utility model discloses a flat cable which comprises a plurality of wire cores in parallel arrangement; each of the wire cores is composed of a middle flat conductor and a flat insulating layer extruded and wrapped on the exterior of the flat conductor; a flat outer sheath is arranged on the outer layers of the wire cores in parallel arrangement; a shielding layer (or a metal shielding layer) can be arranged on the insulating layer and the shielding layer and an armor layer are arranged between the insulating layer and the outer sheath; and when the shielding layer and the armor layer are made of different metal materials, a flat isolating sleeve is extruded and wrapped between the shielding layer and the armor layer, so as to separate the shielding layer from the armor layer. The appearance of the flat cable is flat-shaped and the conductor and the insulating layer in the flat cable are also flat-shaped, so that the whole bending property of the flat cable is greatly increased.
Description
Technical field
The utility model belongs to the field that power cable is made; Be specifically related to a kind of flat cable or be referred to as flat cable; Electrical equipment between the adverse circumstances mobile appliance equipments such as this cable is widely used in generating electricity, metallurgy, chemical industry, harbour connects, and in elevator, mine, electric energy transmitting is used when laying serious bending such as the flat small space in path and back and forth movement.
Background technology
As everyone knows; Whether flat cable is compared with the circle cable using the main distinction and in is convenient to twine, and we often see large-scale rail mounted hoisting equipment, and the cable major part of traction all is a flat cable; Walking along with hoisting equipment; Flat cable always constantly is wrapped on the cable drum, arrange very neat, if round cable has just been arranged not as the flat cable marshalling; Flat cable is mainly used in to move and lays simultaneously; The circle cable is used for fixing laying more; Flat cable back and forth bending number of times greater than the circle cable; Long service life, and during split conductor the heat radiation of flat cable than round cable good heat dissipation, and in narrow and small flat space the circle cable since the characteristics of mechanism size can't adapt to.
Find have the cable colleague to invent multiple flat cable through retrieval, but it all is the improvement of on existing round cable basis, carrying out; Make it to become flat cable; But still adopt round insulation core structure in the middle of the cable, then the parallel in-line arranged side by side of circular core is arranged, extrude restrictive coating and constitute flat cable; Though this structure has strengthened bending property; Yet the outside dimension of round insulation core (insulated wire cores of big especially slightly specification) has determined the gauge of flat cable, when its wide-angle is crooked, and the bending radius that inner tension force that circular core bore and shearing force have had a strong impact on cable; Though than the obvious improvement of round cable, it also has very big room for improvement.
The utility model content
The purpose of the utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of bending property better flat cable.
A kind of flat cable, this cable comprise some cores that are arranged in parallel, and said core is by the conductor of the flat of centre, and the insulating barrier formation that outside the conductor of flat, extrudes flat; The core skin that is arranged in parallel is provided with the oversheath of flat.
Screen or metal screen layer are set in insulating barrier, screen and armour are set between insulating barrier and oversheath.When screen and armour are the different metallic material, between screen and armour, extrude the flat separation sleeve it is separated.
The utility model not only profile is a flat, and its conductor inside and insulating barrier etc. also are flat, have improved the bending property of whole cable greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Like Fig. 1, a kind of flat cable of the utility model comprises some cores that are arranged in parallel, and said core is by the conductor 1 of the flat of centre, and insulating barrier 2 formations that outside the conductor 1 of flat, extrude flat; The core skin that is arranged in parallel is provided with the oversheath 3 of flat.According to different demands, screen (can be metal screen layer) can also be set in insulating barrier 2, screen and armour are set between insulating barrier and oversheath.
The manufacturing approach of the utility model; The soft junction structure conductor that is about to cable is restrainted strand or multiple strand with high multiple lay ratio, when extruding insulation, places the flat mould that meets the demands before the extruder head; Make conductor be flat through the back therebetween; The mould of extruding insulation also is the flat of respective design, has formed the insulated wire cores shape of flat after insulating exruded, then it is arranged according to sign regulation in-line arranged side by side; Use the flat mould to extrude restrictive coating, wherein screen and armour can be set as required certainly.But when screen and armour are the different metallic material, should adopt and extrude separation sleeve (flat) it is separated.
The conductor of this flat cable is applicable to any conductor among the GB/T 3986-2008, can be prefabricated, also can produce the insulation before handle temporarily, as long as satisfy the flat structure of conductor; The gauge of flat conductor can reduce as required as much as possible, specifically can and use the actual needs of the decorum to confirm according to specifications and models, when it becomes very flat, naturally its width will correspondingly increase, belongs to normal phenomenon;
The insulating material of described flat cable can be any insulating material as electric wire under the prior art, is not limited to any or different materials, as long as it can satisfy flat and extrude, the type of employing can be selected for use according to concrete needs.
The sheath material of described flat cable can be any sheath material as electric wire under the prior art, is not limited to any or different materials, as long as it can satisfy flat and extrude, the type of employing can be selected for use according to concrete needs.
The insulating core number of described flat cable can design according to actual needs; The shielding of flat cable and armoring material can be any shielding and the armoring materials as electric wire under the prior art; Be not limited to any or different materials; As long as it can satisfy cable and become flat, the type of employing can be selected for use according to concrete needs.
The profile of the utility model cable is the flat structure; The cable combination that can be any electric pressure and model specification in this structure forms; Its present position can change, and is flat as long as keep conductor and insulated wire cores and whole cable, and every do not have substantial change to the utility model said method; Only just can reach a certain or whole function and effects, all belong to this patent protection range through simple assembling.
Claims (3)
1. a flat cable is characterized in that, this cable comprises some cores that are arranged in parallel, and said core is by the conductor (1) of the flat of centre, and insulating barrier (2) formation that outside the conductor (1) of flat, extrudes flat; The core skin that is arranged in parallel is provided with the oversheath (3) of flat.
2. flat cable according to claim 1 is characterized in that, screen or metal screen layer are set in insulating barrier, and screen and armour are set between insulating barrier and oversheath.
3. flat cable according to claim 2 is characterized in that, between screen and armour, extrudes the flat separation sleeve.
