Abstract

本实用新型公开了一种光纤软电缆，属于电缆领域，包括内芯，所述内芯为不导电的柔软材质，内芯外层绞合有导电体，在所述导电体外周设置有绝缘层，在内芯内设置有闭合的支撑架，所述支撑架内部中心处设置有光纤；由于在线缆的中间设置了不导电且柔软的内芯，导电体绞合在内芯外层，使得导电体间的节距增大，增强了整个电缆的柔软性，且增加了导电体的直径，减少了集肤效应，使得导电体得到充分利用，增强了导电性能；同时，在内芯内设有光纤，可以同时传输光纤信号，节约了线缆材料，且内芯内的不导电材料和支撑架保证了光纤与导电体间不会互相干扰，方便实用。

Description

一种光纤软电缆
技术领域
本实用新型涉及一种电缆，特别是一种同时可以传输光纤信号的电缆。
背景技术
为了移动的方便性，常常需要软电缆。但是，目前的软电缆的导电体一般采用铜或者铝，它们直接束制后绞合而成，这种方式制成的软电缆整体弯曲性和柔软程度不好，达不到要求。另外，现在的软电缆的导电体都位于整个电缆的中间，当交变电流通过导电体时，尤其当电流以较高频率的电子在导电体中传导时，会产生集肤效应，即电流会只集中地从导电体的表面通过，这样，导电体中间的部分就起不到导电的效果，使得这部分导电体白白浪费，使用效率不高。
另外，由于通信光纤技术的发展和普及，光纤技术应用越来越广，一些移动式设备常常需要光纤信号，但是目前的软电缆都不具有光纤传输功能，需要另外的光纤信号线缆，使得成本增加，线缆繁杂，非常不方便。
实用新型内容
本实用新型的发明目的在于：针对上述存在的问题，提供一种同时兼具光纤信号传输、导电体使用效率高、成本低的新型电缆。
本实用新型采用的技术方案是这样的：一种光纤软电缆，包括内芯，所述内芯为不导电的柔软材质，内芯外层绞合有导电体，在所述导电体外周设置有绝缘层，在内芯内设置有闭合的支撑架，所述支撑架内部中心处设置有光纤。
作为优选：所述支撑架为正三角形。
作为优选：所述内芯为橡胶条。
综上所述，由于采用了上述技术方案，本实用新型的有益效果是：由于在线缆的中间设置了不导电且柔软的内芯，导电体绞合在内芯外层，使得导电体间的节距增大，增强了整个电缆的柔软性，且增加了导电体的直径，减少了集肤效应，使得导电体得到充分利用，增强了导电性能；同时，在内芯内设有光纤，可以同时传输光纤信号，节约了线缆材料，且内芯内的不导电材料和支撑架保证了光纤与导电体间不会互相干扰，方便实用。
附图说明
图1是本实用新型的横切面图。
图中标记：1为内芯，2为导电体，3为绝缘层，4为支撑架，5为光纤。
具体实施方式
下面结合附图，对本实用新型作详细的说明。
为了使本实用新型的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本实用新型进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本实用新型，并不用于限定本实用新型。
如图1所示，一种光纤软电缆，包括内芯1，内芯1为橡胶条，内芯1外层绞合有导电体2，在所述导电体2外周设置有绝缘层3，在内芯1内设置有闭合的支撑架4，支撑架4为正三角形，所述支撑架4内部中心处设置有光纤5。
由于在线缆的中间设置了橡胶条的内芯1，它具有不导电和柔软的性能，导电体2绞合在内芯1外层，使得导电体2间的节距增大，增强了整个电缆的柔软性，且增加了导电体2的直径，减少了集肤效应，使得导电体2得到充分利用，增强了导电性能；同时，在内芯1内设有光纤5，可以同时传输光纤信号，节约了线缆材料，且内芯1内的不导电材料塞满整个内芯和支撑架4内的空隙，保证了光纤的稳定，同时保证了光纤与导电体间不会互相干扰，方便实用。
以上所述仅为本实用新型的较佳实施例而已，并不用以限制本实用新型，凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型的保护范围之内。
