Background
In the event of ultra-high speed launch, penetration/impact etc of the model/projectile, the model or projectile will be subjected to an overload acceleration of tens of thousands G, with the greater the overload acceleration produced as the speed of launch or penetration increases.
To achieve a specific function, it is often necessary to install multiple levels of electronics inside the model/projectile. For example, a telemetering model, in order to realize measurement of flight parameters of the model, a sensor array, a data processing module, a data sending module, a power supply module and the like are arranged in the model; for example, armor piercing bombs are generally internally provided with a sensing module, a control module, a power supply module, initiating explosive devices and the like in order to realize delayed detonation of a bomb body. In order to ensure that the electronic equipment installed inside can work normally in the process of bearing high overload on the model/projectile body, the reliability of the inter-stage cable connection of the electronic equipment is very important besides improving the overload resistance of the electronic equipment.
Electronic equipment inside the model/projectile body generally adopts a step-by-step filling process to ensure the overload resistance of the electronic equipment, but in the process that the model/projectile body bears high overload, due to the occurrence of impact stress, a certain degree of slippage phenomenon is generated between all stages of electronic equipment on a connecting interface, and the phenomenon can cause the damage of an interstage connecting cable to cause the failure of circuit functions.
In order to reduce the connection failure risk of the interstage cable inside the model/projectile body under the high overload environment, the development of a interstage cable connection method for high overload electronic equipment is needed at present.
