Background
Along with the deepening of the integrated design, the missile is provided with a comprehensive maintenance electrical interface for testing and initiating explosive device protection, and the comprehensive maintenance interface is designed into a multi-cavity comprehensive connector. In the missile electrical initiating explosive device ignition control circuit, a current limiting resistor used for controlling the ignition current is specially designed. Such current limiting resistors are typically designed in electrical control devices or specialized power distribution equipment separately from the multi-cavity integrated connector. The detection of the current limiting resistor takes measures of breaking a circuit because the initiating explosive device or a sensitive device is connected in the initiating explosive device ignition control circuit. It is often the case that since resistors are already built into the circuitry in the device, separate disassembly of the control device or the distribution equipment is required to detect such critical resistive devices, which are often not detectable in the event of unsatisfactory disassembly conditions. Designing the resistors as separate devices to enable individual detection of such resistors increases the spring-up construction occupation and the number of connector devices.
