摘　　要：通过对粗细电缆连接可靠性控制的研究和应用,指出被连接电缆本身的阻抗匹配性、电缆与连接器的阻抗匹配性以及电缆和连接器连接操作过程的规范性是影响粗细电缆连接可靠性的三个主要因素。为此,建立了粗细电缆可靠连接控制流程和装接操作规范,实现了外径约22mm的SYV-50-17粗电缆与外径约10mm的SYV-50-7细电缆的可靠连接,应用结果表明粗细电缆连接后连接处反射系数小于1.5%。On the basis of the research and application of the reliability control for the connection between thick and thin cables, it is pointed out that the impedance matching score of the connected cables themselves, the impedance matching score between connectors and cables, and the normativity of the connecting operation are the three main factors affecting the connection reliability between thick and thin cables. Therefore the control flow and operation criterion for reliably connecting thick and thin cables are established, realizing the reliable connection between the thick cable, SYV-50-17, whose out-diameter is about 22 mm, and the thin cable, SYV-50-7, whose out-diameter is about 10 mm. The application result shows that the reflection coefficient at the connecting point is lower than 1. 5 % after the connection of thick and thin cables.
