Multistage rocket separation electric connector insertion state detection device and rocket thereof

Abstract

The invention relates to the technical field of aerospace, in particular to a multistage rocket separation electric connector insertion state detection device and a rocket thereof. According to the multi-stage rocket separation electric connector insertion state detection device, no matter when the separation electric connector in each stage is used for ground testing or flying in the air, only asignal line led out from a negative bus is connected with the intelligent detection combination of the stage, and the transmission of an insertion state signal is realized. Therefore, the number of cores used for detecting the plugging state of the separated electric connector of each stage is one, the occupied number of cores is saved by about 75% compared with a traditional detection method, thesize of the separated electric connector is reduced, the connection complexity and weight of a cable network are reduced, and the carrying capacity of a rocket is improved.

Description

technical field [0001] The present application relates to the field of aerospace technology, in particular to a multi-stage rocket separation electrical connector mating state detection device and the rocket. Background technique [0002] In general, the power supply and distribution and timing control of multi-stage rockets adopt a centralized control method, and there are many signal flows and paths between rocket stages. higher requirements. At the same time, during the flight of the rocket, it needs to experience complex mechanical, thermal and electromagnetic environments. If the electrical connector fails to be reliably connected or the electrical connector fails to separate due to some kind of stress, the power supply and distribution and timing between the stages of the rocket There will be a short circuit or an open circuit in the control, which will lead to immeasurable consequences such as rocket flight failure. Real-time monitoring to provide more measurement d...

Problems solved by technology

[0006] The disadvantage of the detection device in the above prior art is that too many cores are occupied on the separate electrical connectors. As shown in the figure, each pair of separate electrical connectors occupies four cores.

The separation connector is a bridge for the signal connection of each cabin section of the rocket. If there are too many cores, the cross-sectional area of ​​the separation electrical connector will be increased, thereby increasing the thickness and weight of the rocket cabin section; at the same time, the separation electrical connector As the number of cores increases, the size and weight of the corresponding cable network will also increase, which will affect the carrying capacity and production cost of the rocket.
