Description
技术领域 technical field
本实用新型涉及一种在移动场合使用的输电线缆，特别是一种质地柔软、输电性能好的软电缆。The utility model relates to a power transmission cable used in mobile places, in particular to a flexible cable with soft texture and good power transmission performance.
背景技术 Background technique
现有技术的软电缆，导体为束制或束制后再绞合而成，导体外径小，束制和绞合时均有一定的节距，而且节距较小，使电缆整体弯曲性能和柔软程度降低。同时，现有技术输电线缆，通常中间直接为导体，当交变电流通过导体时，尤其使电流或电压以频率较高的电子在导体中传导时，会产生集肤效应，电流将集中在导体表面流过，聚集于总导体表层，而非平均分布于整个导体的截面积中。采用这样的设计，导致导体的中心部分的缆线往往起不到导电的效果，对于中心部分的缆线本身是一种浪费，而且要想增加电缆的载流量，必须使导体部分加粗，这在无形中也增加了线缆的材料成本和重量。In the flexible cables of the prior art, the conductors are bundled or bundled and then twisted. The outer diameter of the conductors is small, and there is a certain pitch when bundled and twisted, and the pitch is small, so that the overall bending performance of the cable is improved. and reduced softness. At the same time, the current transmission cables in the prior art usually have a conductor directly in the middle. When the alternating current passes through the conductor, especially when the current or voltage is conducted in the conductor with electrons of higher frequency, a skin effect will be generated, and the current will be concentrated in the conductor. The conductor surface flows through and gathers in the total conductor surface layer, rather than being evenly distributed in the cross-sectional area of the entire conductor. With such a design, the cable in the central part of the conductor often does not have the effect of conducting electricity, which is a waste of the cable in the central part, and in order to increase the carrying capacity of the cable, the conductor part must be thickened. It also increases the material cost and weight of the cable virtually.
实用新型内容Utility model content
本实用新型目的是为了解决现有技术中输电线缆柔性差，且导电效率低的缺陷，提供了一种软电缆。The purpose of the utility model is to provide a flexible cable in order to solve the defects of poor flexibility and low conduction efficiency of the power transmission cable in the prior art.
为了实现上述目的，本实用型公开了一种软电缆，包括不导电的内芯，在内芯外层绞合有导体，在导体外层挤包有绝缘层。In order to achieve the above purpose, the utility model discloses a flexible cable, which includes a non-conductive inner core, a conductor is twisted on the outer layer of the inner core, and an insulating layer is extruded on the outer layer of the conductor.
本实用新型中，所述内芯为为软塑料填充条、橡胶填充条、麻绳，或其他不导电的柔性材质料制成的内芯，可根据对电缆使用环境的不同进行选用。In the utility model, the inner core is made of soft plastic filling strips, rubber filling strips, hemp rope, or other non-conductive flexible materials, which can be selected according to the different environments in which the cables are used.
本实用新型中，所述导体为实心导体或多根单线以同一方向一次性束合而成的束线。当导电截面较小时，由于束线单线丝径过小，难以加工，容易断裂，较好采用实心导体。当导电截面较大时，为更好的提高柔软性能，较好采用束线。In the utility model, the conductor is a solid conductor or a bundle formed by bundling multiple single wires in the same direction at one time. When the conductive cross-section is small, it is difficult to process and easy to break due to the small wire diameter of the wire harness, so it is better to use a solid conductor. When the conductive cross-section is large, in order to better improve the flexibility, it is better to use bundled wires.
本实用新型中，为更好地提高柔软性能和输电性能，绞合时节距为通常绞合导体的1.2-5倍。In the utility model, in order to better improve the soft performance and power transmission performance, the pitch during twisting is 1.2-5 times of the usual twisted conductor.
本实用新型在电缆中加入柔软材料的方法，可以提高电缆抗弯曲性，增加整个电缆的柔软性能，能够应用在频繁移动场合。同时。填充内芯，增加导体外径，能降低导体集肤效应的影响，可以减少导体材料用量，提高输电性能，增加电缆的载流量。The method of adding soft material to the cable in the utility model can improve the bending resistance of the cable, increase the flexibility of the whole cable, and can be used in frequent moving occasions. at the same time. Filling the inner core and increasing the outer diameter of the conductor can reduce the influence of the conductor skin effect, reduce the amount of conductor material, improve the power transmission performance, and increase the current carrying capacity of the cable.
