具体实施方式Detailed ways

如图1、2、3所示，组合信号电缆，包括数据线1、屏蔽控制线2、双绞屏蔽信号线3、地线4、绝缘层5、护套6，数据线1外设有数根屏蔽控制线2、双绞屏蔽信号线3及地线4，在数根屏蔽控制线2、双绞屏蔽信号线3及地线4外依次设有绝缘层5、数根双绞屏蔽信号线3、一层绝缘层5及护套6。数据屏蔽控制线2为十三根，并采用不同颜色相区分，每根屏蔽控制线2的导电线芯截面积为0.35mm²，屏蔽层2-3为聚酯/铝复合薄膜屏蔽层。数据双绞屏蔽信号线3为十四根，在双绞屏蔽信号线3之间并采用不同颜色相区分，每根双绞屏蔽信号线3的导电线芯截面积为0.2mm²。双线屏蔽信号线3的屏蔽层3-4为镀锡铜线屏蔽层。绝缘层5为聚酯薄膜绝缘层。护套6为氨酯护套。数据线1为超五类四对屏蔽数据线。 As shown in Figures 1, 2, and 3, the combined signal cable includes a data line 1, a shielded control line 2, a twisted pair shielded signal line 3, a ground line 4, an insulating layer 5, and a sheath 6. There are several data lines outside the data line 1. Shielded control wires 2, twisted-pair shielded signal wires 3 and ground wires 4, an insulating layer 5 and several twisted-pair shielded signal wires 3 are arranged in sequence outside several shielded control wires 2, twisted-pair shielded signal wires 3 and ground wires 4 , a layer of insulating layer 5 and sheath 6. There are thirteen data shielding control lines 2, which are distinguished by different colors. The cross-sectional area of the conductive core of each shielding control line 2 is 0.35mm ² , and the shielding layer 2-3 is a polyester/aluminum composite film shielding layer. There are fourteen data twisted-pair shielded signal wires 3 , which are distinguished by different colors among the twisted-pair shielded signal wires ³ . The shielding layer 3-4 of the double-wire shielded signal line 3 is a tinned copper wire shielding layer. The insulating layer 5 is a polyester film insulating layer. The sheath 6 is a urethane sheath. Data line 1 is a Category 5e four-pair shielded data line.

屏蔽控制线2由镀锡铜绞线芯2-1外依次设有聚乙烯绝缘层2-2、聚酯/铝复合薄膜屏蔽层2-3构成。双绞屏蔽信号线3，包括两根信号线，每根信号线由镀锡铜绞线芯3-1外包覆聚乙烯绝缘层3-2构成，两根信号线绞合后，再依次绕包聚酯薄膜3-3、编织镀锡铜线屏蔽层3-4。根据市场要求电缆应具有一定的抗电磁干扰能力，因此在工艺设计时，我们将4×2×0.51mm²的超五类四对屏蔽数据线作为缆芯，对控制线和信号线都采用了屏蔽结构，该屏蔽形式的设计不仅具有一定的抗干扰能力而且增加了电缆本身的柔软性又减轻电缆重量。从对电缆重量的要求方面考虑，由于聚酯/铝复合薄膜的比重要比铜的比重低得多，故0.35mm²屏蔽控制线采用了绕包聚酯/铝复合薄膜屏蔽形式，使得电缆的重量有所降低。由于绝缘单线绝缘层薄，易被屏蔽层金属碰伤造成电击穿，所以确定了在控制线和对绞屏蔽信号线组外及绞缆线芯外绕包一层聚酯薄膜以保护绝缘线芯。 The shielded control wire 2 is composed of a tinned copper stranded wire core 2-1 with a polyethylene insulating layer 2-2 and a polyester/aluminum composite film shielding layer 2-3 in sequence. Twisted-pair shielded signal wires 3, including two signal wires, each signal wire is composed of a tinned copper twisted core 3-1 covered with a polyethylene insulating layer 3-2, after the two signal wires are twisted, they are wound in sequence Wrap polyester film 3-3, braided tinned copper wire shielding layer 3-4. According to market requirements, the cable should have a certain ability to resist electromagnetic interference. Therefore, in the process design, we use 4 × 2 × 0.51mm ² super category five four-pair shielded data cable as the cable core, and use Shielding structure, the design of this shielding form not only has a certain anti-interference ability but also increases the flexibility of the cable itself and reduces the weight of the cable. Considering the requirements on the weight of the cable, since the specific gravity of the polyester/aluminum composite film is much lower than that of copper, the 0.35mm ² shielded control line adopts the wrapping polyester/aluminum composite film shielding form, so that the cable Weight has been reduced. Because the insulating layer of the insulating single wire is thin, it is easy to be damaged by the metal of the shielding layer and cause electric breakdown. Therefore, it is determined to wrap a layer of polyester film outside the control line and the twisted shielded signal line group and outside the core of the twisted cable to protect the insulated wire. core.
