【技术领域】【Technical field】

本发明涉及一种线缆，尤其涉及一种具有抗电磁干扰功能的线缆。The invention relates to a cable, in particular to a cable with anti-electromagnetic interference function.

【背景技术】【Background technique】

目前，电子设备使用过程中，或多或少会出现电磁干扰，怎样提高抗电磁干扰能力是电子行业所必须解决的问题。除了对电子组件本身提出增加抗电磁干扰部件的功能外，还要求对电子组件的线缆增加抗电磁干扰的功能。At present, during the use of electronic equipment, electromagnetic interference will occur more or less. How to improve the ability to resist electromagnetic interference is a problem that the electronics industry must solve. In addition to adding the function of anti-electromagnetic interference components to the electronic components themselves, it is also required to add anti-electromagnetic interference functions to the cables of the electronic components.

于2001年8月11日中国台湾专利公告第450408号揭露了一种线缆结构，该线缆由若干条细线缆所包覆而成，其包括在最内层具有数条细线缆，于该等细线缆外包覆有一第一隔离层，该第一隔离层为一铝箔材质，于第一隔离层外再包覆有一第二隔离层，第二隔离层为导电塑料材质，在第一隔离层与第二隔离层之间另具有一条接地线，最后在该第二隔离层外缘再包覆有一绝缘层。该线缆确实在很大程度上降低电磁干扰，但是，该线缆为增加抗电磁干扰的能力，使用多个隔离层，且生产工艺较复杂，加工成本较高。On August 11, 2001, Taiwan Patent Publication No. 450408 disclosed a cable structure, the cable is covered by several thin cables, including several thin cables in the innermost layer, The thin cables are covered with a first isolation layer, the first isolation layer is made of an aluminum foil material, and a second isolation layer is coated outside the first isolation layer, and the second isolation layer is made of a conductive plastic material. There is another ground line between the first isolation layer and the second isolation layer, and finally an insulating layer is coated on the outer edge of the second isolation layer. The cable does reduce electromagnetic interference to a great extent, however, in order to increase the ability of resisting electromagnetic interference, the cable uses multiple isolation layers, and the production process is complicated and the processing cost is high.

因此，有必要提供一种线缆来克服上述问题。Therefore, it is necessary to provide a cable to overcome the above problems.

图2为图1所示线缆的正视图。Fig. 2 is a front view of the cable shown in Fig. 1 .

【具体实施方式】【Detailed ways】

请参照图1至图2所示，本发明线缆1包括接地线2、信号线3、包覆信号线3的绝缘皮4及包覆接地线2与绝缘皮4的导电体5。Referring to FIGS. 1 to 2 , the cable 1 of the present invention includes a ground wire 2 , a signal wire 3 , an insulation 4 covering the signal wire 3 , and a conductor 5 covering the ground wire 2 and the insulation 4 .

接地线2、信号线3为具有传导功能的金属线，其材质为铜、铝等现有的金属线。The ground wire 2 and the signal wire 3 are metal wires with a conduction function, and their materials are existing metal wires such as copper and aluminum.

导电体5具有两层，包括导电性较好的外层51与相对外层51的导电性较弱的内层52。导电体5经过弯折形成三层结构，包括第一层501、第二层502及第三层503，上述三层依次上下排列，第一层501与第三层503相连接，第二层502与第三层503相连接，第二层502位于第一层501与第三层503之间。外层51位于整条线缆1的外围，第一层501中，外层51位于内层52上方，第二层502中，外层51位于内层52上方，第三层503中，外层51位于内层52下方。The conductor 5 has two layers, including an outer layer 51 with better conductivity and an inner layer 52 with lower conductivity than the outer layer 51 . The conductor 5 is bent to form a three-layer structure, including a first layer 501, a second layer 502 and a third layer 503. The above three layers are arranged up and down in sequence. It is connected with the third layer 503 , and the second layer 502 is located between the first layer 501 and the third layer 503 . The outer layer 51 is located on the periphery of the entire cable 1. In the first layer 501, the outer layer 51 is located above the inner layer 52; in the second layer 502, the outer layer 51 is located above the inner layer 52; in the third layer 503, the outer layer 51 is located below the inner layer 52 .

接地线2为裸露的金属导体，位于第一层501与第二层502之间，其接地线2与导电体5的外层51及导电体5的内层52均相接触，接地线2位于第一层501中的内层52与第二层502的外层51之间。The ground wire 2 is a bare metal conductor, located between the first layer 501 and the second layer 502, the ground wire 2 is in contact with the outer layer 51 of the conductor 5 and the inner layer 52 of the conductor 5, and the ground wire 2 is located in the between the inner layer 52 of the first layer 501 and the outer layer 51 of the second layer 502 .

绝缘皮4位于第二层502与第三层503之间，其绝缘皮4与导电体5的内层52相接触，接地线2位于第一层501中的内层52与第二层502的内层52之间。具有绝缘皮4的若干信号线3排成一列，当然，在其它实施方式中，若干信号线3也可堆叠在一起。The insulating skin 4 is located between the second layer 502 and the third layer 503, the insulating skin 4 is in contact with the inner layer 52 of the conductor 5, and the grounding wire 2 is located between the inner layer 52 of the first layer 501 and the inner layer 502 of the second layer 502. between inner layers 52 . Several signal wires 3 with insulating skin 4 are arranged in a row, of course, in other implementation manners, several signal wires 3 can also be stacked together.

外层51材质为金属箔，也可以为具有金属镀层的纤维织品，内层52具有黏性的导电胶(未图示)。内层52作为包覆时黏着固定之用，导电胶上散布有传导作用的导体粉末(未图示)，而导体粉末并非为连接传导路径，其导通阻值较高，其传导方式在工程中称为垂直导通，相对材质为金属箔的外层51(水平导通)的阻值会较高。因阻值的高低与抗电磁干扰的能力为反比，所以，降低阻值可以提高抗电磁干扰能力。本发明通过阻值较小的外层51与接地线2相接触，可以降低整条线缆1的阻值，从而，提高抗电磁干扰能力。The outer layer 51 is made of metal foil, or fiber fabric with metal plating, and the inner layer 52 is made of viscous conductive glue (not shown). The inner layer 52 is used for adhesion and fixing during coating. Conductive conductive powder (not shown) is scattered on the conductive adhesive. The conductive powder is not used to connect the conductive path, and its conduction resistance is relatively high. It is called vertical conduction in , and the resistance value of the outer layer 51 (horizontal conduction) which is made of metal foil will be higher. Because the resistance value is inversely proportional to the ability to resist electromagnetic interference, reducing the resistance value can improve the ability to resist electromagnetic interference. In the present invention, the resistance of the entire cable 1 can be reduced through the contact of the outer layer 51 with a small resistance with the grounding wire 2, thereby improving the anti-electromagnetic interference capability.

本发明仅通过一条导电体5，能使内层52包覆接地线2，又能使外层51与接地线2接触以提高更好的传导作用。生产工艺简单，制作方便。The present invention enables the inner layer 52 to cover the grounding wire 2 and the outer layer 51 to contact the grounding wire 2 through only one conductor 5 to improve better conduction. The production process is simple and the production is convenient.
