背景技术Background technique
目前市场上可分离的自乘式结构的电缆比较多，但大多都是“8”字型结构的电缆，整缆由上下两个圆形结构的部分加中间的吊带构成，电缆结构中上面圆形部分由钢丝加护套构成，下面圆形部分由常规电缆构成，中间连接有一定高度和宽度的吊带。这类结构电缆存在以下缺点：At present, there are many cables with separable self-propelled structure on the market, but most of them are cables with "8" shape structure. The shaped part is composed of steel wire and sheath, the lower circular part is composed of conventional cables, and a sling with a certain height and width is connected in the middle. This type of structural cable has the following disadvantages:
1、中间吊带不易分离；1. The middle sling is not easy to separate;
2、由于上下都是圆形且中间连接有吊带，整体尺寸较大，不易安装敷设；2. Since the top and bottom are round and there is a sling connected in the middle, the overall size is large and it is not easy to install and lay;
3、一般上面圆形结构只是整缆的承重部分，不具有光信号或者电信号的传输功能。3. Generally, the above circular structure is only the load-bearing part of the whole cable, and does not have the transmission function of optical or electrical signals.
实用新型内容Utility model content
本实用新型所要解决的技术问题是提供一种易分离型光电混合缆，易于分离，尺寸小。The technical problem to be solved by the utility model is to provide an easy-to-separate optical-electrical hybrid cable, which is easy to separate and small in size.
为解决上述技术问题，本实用新型易分离型光电混合缆，包括两根蝶形光缆和圆形网线，所述蝶形光缆竖立并排安放，构成矩形结构；所述圆形网线位于蝶形光缆下方，两根蝶形光缆与圆形网线外具有外护套，在蝶形光缆与圆形网线连接处，所述外护套上形成有左右对称的分离槽。In order to solve the above-mentioned technical problems, the easily separable optoelectronic hybrid cable of the present invention includes two butterfly optical cables and a circular network cable. The butterfly optical cables are erected and arranged side by side to form a rectangular structure; , the two butterfly optical cables and the circular network cable are provided with an outer sheath, and a left-right symmetrical separation groove is formed on the outer sheath at the connection between the butterfly optical cable and the circular network cable.
具体地，所述蝶形光缆具有光纤和钢丝。所述圆形网线内具有十字形骨架，所述十字形骨架上具有导体，所述导体外具有绝缘层。Specifically, the butterfly cable has optical fibers and steel wires. The circular network cable has a cross-shaped skeleton inside, a conductor on the cross-shaped skeleton, and an insulating layer outside the conductor.
为了便于撕裂，在圆形网线的外护套内具有撕裂绳。In order to facilitate tearing, there is a tear cord inside the outer sheath of the circular mesh wire.
本实用新型在光缆护套和网线护套连接处左右对称设计“7”形的可分离槽口(分离槽)，便于使用时将两者分离。取消常规的吊带连接形式，利用光缆护套的下边与网线护套相连，由于取消了吊带，且光缆和网线部分共用护套， 可以减小整缆的尺寸。通过设计特殊模具，将混合缆上面部分根据蝶形光缆的形状，做成矩形结构，既可以避免光缆的翻身，又减小了成品外径，可以将护套的厚度做到均匀一致。The utility model designs a "7"-shaped separable notch (separation groove) symmetrically on the left and right at the connection between the optical cable sheath and the network cable sheath, which is convenient for separating the two during use. The conventional sling connection form is cancelled, and the lower edge of the optical cable sheath is used to connect with the network cable sheath. Since the suspension strap is cancelled, and the optical cable and the network cable share the sheath, the size of the entire cable can be reduced. By designing a special mold, the upper part of the hybrid cable is made into a rectangular structure according to the shape of the butterfly optical cable, which can not only avoid the overturning of the optical cable, but also reduce the outer diameter of the finished product, and the thickness of the sheath can be made uniform.
与现有技术相比，优点如下：Compared with the existing technology, the advantages are as follows:
1、本实用新型采用对称“7”形易分离槽口的结构设计，该结构形式易于将在连接处将两者分离，便于后期的安装敷设。1. The utility model adopts the structural design of the symmetrical "7"-shaped easy-to-separate notch, which is easy to separate the two at the connection, which is convenient for later installation and laying.
2、取消常规吊带的连接形式，采用上下两部分共用护套的形式，将两者连接在一起，不仅成品外径更小，而且结构更加的紧凑稳定。2. The connection form of the conventional sling is cancelled, and the upper and lower parts share a sheath to connect the two together, not only the outer diameter of the finished product is smaller, but also the structure is more compact and stable.
3、将易分离型光电混合缆上面部分根据光缆的形状设计成矩形结构，该结构形式即解决了光缆翻身的问题，又减小了该部分的尺寸。3. The upper part of the easily separable optoelectronic hybrid cable is designed into a rectangular structure according to the shape of the optical cable, which not only solves the problem of turning over the optical cable, but also reduces the size of this part.
4、将蝶形光缆和网线连接在一起，使整缆既有传输光信号的能力，也具有传输电信号的能力。4. Connect the butterfly optical cable and the network cable together, so that the entire cable has the ability to transmit both optical signals and electrical signals.
5、整体挤出外护套(聚氯乙烯护套)，成品具有结构紧凑，外径小，易于分离等优点。5. The outer sheath (polyvinyl chloride sheath) is extruded as a whole, and the finished product has the advantages of compact structure, small outer diameter and easy separation.
