[0025] An active separation device between a comprehensive helmet and an ejection seat during ejection rescue includes a anti-loose connector, which is selected according to the use requirements of the comprehensive helmet circuit, and contains a plug 4 and a socket 7. A pull-off cable 1 is installed on the unlocking mechanism of the plug 4, and the pull-off cable 1 is fixed along the axis of the cable 3 through the cable fixing ring 2. There is enough space above the pull-off cable 1 for hand operation.

[0026] The ejection seat 8 is used as a fixed reference, the electrically excited powder gas mechanism 9 is fixed to the ejection seat 8, the socket 7 can be connected to the ejection seat 8 through the socket fixing mechanism 11 and is firmly fixed to the designed position of the ejection seat 8. A rotatable lever clamping mechanism 10 is installed in the middle of the socket fixing mechanism 11. The fulcrum of the lever clamping mechanism 10 is connected to the socket fixing mechanism 11 to form a lever structure. The power end of the lever clamping mechanism 10 is aligned with the electrically excited powder gas mechanism 9. The resistance end of the lever clamping mechanism 10 corresponds to the spring self-locking mechanism of the plug 4 of the anti-loose connector. When the plug 4 is inserted into the socket 7, the resistance end of the lever clamping mechanism 10 can be pressed into the space between the plug 4 and the socket 7 by the unlocking mechanism, and is fixed by the unlocking mechanism of the plug 4 and cannot rotate freely. The power end should be flat and have a certain force area.

[0027] The plug 4 has a plug alignment positioning mark 5, and the socket 7 has a socket alignment positioning mark 6.

[0028] The lever mechanism 10 includes a long arm and a short arm, which are fixed and rotatably arranged on a rotating shaft. The rotating shaft is fixed to the ejection seat. The nozzle of the electrically excited powder gas mechanism 9 is aligned with the long arm, and the short arm is clamped on the spring self-locking mechanism.

[0029] In daily use, when it is necessary to insert, the plug is placed above the clamping mechanism by one hand, and after the alignment positioning mark is adjusted to be consistent, the plug is inserted into the socket, the spring self-locking device is activated, and the plug, clamping mechanism and socket are firmly fixed; when it is necessary to release, the upper part of the steel cable is pulled by one hand, the steel cable moves axially, drives the spring self-locking device to unlock, and further drives the plug to move axially along the cable, so that the plug is separated from the socket, and the daily use of the comprehensive helmet and the ejection seat is separated.

[0030] In ejection rescue, the ejection speed and posture are judged by the ejection seat program controller, and when the state is appropriate, the electrically activated explosive gas mechanism installed on the seat is activated by the circuit to make the explosive burn, generate gas, and the impact of the ejected gas on the free end of the clamping mechanism makes the free end fall down, the clamping end is raised, and the length difference between the long arm and the short arm of the lever is used to further enhance the thrust of the clamping end, the movement of the clamping end pushes the spring self-locking mechanism of the socket to move upward, overcomes the unlocking force, and further pushes the plug to move upward, so that the plug is separated from the socket, and the active separation of the comprehensive helmet and the ejection seat in emergency ejection is realized.
