Abstract
The utility model discloses a flat wire, which comprises core wires and an outer shield coated outside the core wires. The core wire is formed by stranding a plurality of enameled wires along the clockwise direction or the counter-clockwise direction. The flat wire comprises a plurality of core wires which are parallel to one another and are arranged equidistantly, and the stranding directions of any two adjacent core wires are opposite. Compared with the prior art, the advantages of the flat wire provided by the utility model are as follows: firstly, the extrusion temperature and taking-up and taking-off tension during extrusion processing can be well controlled for the flat wire, the extrusion process is improved, parameters of the extrusion process are easy to adjust and match; secondly, the fraction defective of appearance distortion of the flat wire is reduced, and the flat wire is not easy to deform after being used for a period of time; thirdly, the removing of the internal stress leads the wire to feel more flexible, the obedient degree is better, which more meets requirements of human engineering.
Description
Technical field
The utility model relates to a kind of lenticular wire, the technical field of electric wire, cable.
Background technology
In electric wire, cable technology field, often use lenticular wire.Lenticular wire comprises several heart yearns that are arranged in parallel and coated outer lining (being generally insulating material) outside heart yearn.Wherein heart yearn is twisted together mutually by several enamel covered wires and forms.
Several heart yearns of finishing stranding process are being arranged in parallel together by specific mould, the coated heart yearn of glue-line that is covered outward, the cooling back forms the lenticular wire finished product, and this is that wire rod well-known to those skilled in the art is extruded processing technology.
Extrude at wire rod then and add man-hour, just coated on heart yearn the time when outer lining glue-line, the temperature of rubber is very high, also has certain fluidity (plasticity), in the process of cooling, the enamelled wire that twists mutually in the heart yearn has the trend of scattering, and forms the distortion internal stress in rubber.Usually if wire temperature and extrude power control bad the time during formed product or after using a period of time, is easy to occur local or whole distortion, the out-of-flatness of lenticular wire.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of lenticular wire, described lenticular wire is made up of heart yearn and coated outer lining outside heart yearn, described heart yearn is formed by twisting mutually clockwise or counterclockwise by several enamelled wires, described lenticular wire comprises several heart yearns that are parallel to each other and equidistantly arrange, and the twisted wire direction of adjacent two heart yearns is opposite arbitrarily.
Adopt the lenticular wire of technique scheme, the twisted wire direction of adjacent two heart yearns is opposite, thereby the distortion internal stress that makes adjacent two heart yearns produce can all or part ofly be cancelled out each other, on the one hand, can control the extrusion temperature and the retractable cable tension force in the processing extruded of lenticular wire better, improve expressing technique, made the easier adjustment of each parameter, the collocation of expressing technique; On the other hand, the outward appearance that has reduced the lenticular wire wire rod is twisted fraction defective and is used a period of time to be difficult for torsional deformation; Moreover the elimination of internal stress makes the wire rod feel gentleer, and docile degree is better, more meets the ergonomics requirement.
Preferably, described enamelled wire is an enamel covered wire.
Lenticular wire of the present utility model compared with prior art, on the one hand, can be controlled the extrusion temperature and the retractable cable tension force in the processing extruded of lenticular wire better, has improved expressing technique, makes the easier adjustment of each parameter, the collocation of expressing technique; On the other hand, the outward appearance that has reduced the lenticular wire wire rod is twisted fraction defective and is used a period of time to be difficult for torsional deformation; Moreover the elimination of internal stress makes the wire rod feel gentleer, and docile degree is better, more meets the ergonomics requirement.
Description of drawings
Accompanying drawing 1 is the schematic cross-sectional view of the utility model lenticular wire (arrow is depicted as the twisted wire direction);
1, be covered outward glue-line 2, heart yearn 21, enamel covered wire.
Embodiment
Below in conjunction with drawings and Examples the utility model lenticular wire is specifically described.
Embodiment 1
As shown in Figure 1, a kind of lenticular wire, the heart yearn 2 of lenticular wire and equidistant arrangement parallel by 4 and coated outer lining glue-line 1 outside heart yearn 2 are formed, and the cross section of lenticular wire is roughly ellipticity, and heart yearn 2 fills among the glue-line 1 that is covered outside.Heart yearn 2 is formed by twisting mutually clockwise or counterclockwise by several enamel covered wires 21, and the twisted wire direction of adjacent two heart yearns 2 is opposite arbitrarily.
As shown in Figure 1, arrow is the twisted wire direction of each heart yearn 2, with 4 parallel and equally spaced arrangements of heart yearn 2 (the twisted wire direction of whenever adjacent two heart yearn 2 is opposite) through twisting, together taking out line processing by particular mold (takes out in the process of line processing, constantly in die cavity, inject lining material outside the fusion of flowing, cool off the lenticular wire finished product that just obtains present embodiment afterwards again.
Lenticular wire of the present utility model is not limited to the above embodiments, and all equivalences of doing according to spirit of the present utility model change or modify, and all should be encompassed in the protection range of the present utility model.
Claims (2)
1. lenticular wire, described lenticular wire is made up of heart yearn and coated outer lining outside heart yearn, described heart yearn is formed by twisting mutually clockwise or counterclockwise by several enamelled wires, it is characterized in that: described lenticular wire comprises several heart yearns that are parallel to each other and equidistantly arrange, and the twisted wire direction of adjacent two heart yearns is opposite arbitrarily.
