无论是星上设备还是地面测试设备,都有很多信号连接电缆。在这些设备的研制过程中,特别是在测试时,不可避免地要多次插拔这些电缆。反复的插拔增大了插接错误的危险。在过去的实践中,因种种原因而使电缆接插错误造成设备损坏的情况不胜枚举,因而也经常给人们带来所谓“责任事故”的精神紧张。为避免这些情况发生,应该有一种办法,它保证接 Whether it is an on-board device or a ground test device, there are many signal connection cables. In the course of the development of these devices, especially when testing, it is unavoidable to plug and pull these cables several times. Repeated plugging increases the risk of plugging errors. In the past practice, due to a variety of reasons, the cable plugging errors caused by equipment damage are numerous, and therefore often give people the so-called “responsibility” of the nervous. To avoid these situations, there should be a way to ensure that
