Description

Technical Field

[0001] The present invention relates to the field of missile booster separation technology, and in particular to a missile floating interstage connector and a separation method thereof. Background Art

[0002] To increase the range of tactical missiles or achieve a certain initial velocity, a booster is typically added to the missile's tail. After the booster's operation is complete, the booster and missile are structurally and electrically separated. To achieve this, two pairs of locating pins and holes, a pair of connectors (consisting of a plug and socket), and a set of explosive bolts are typically fixed at the separation surface between the booster and missile. When the booster and missile are assembled, the plug and socket must be engaged simultaneously while the two pairs of locating pins and holes mate, and then the explosive bolts are installed.

[0003] However, due to the processing errors and installation position errors among the locating pins, locating holes, plugs and sockets, especially for large-diameter missiles, the errors will be greater, which will inevitably make it impossible for the plug pins and socket holes to be completely coaxially aligned. More seriously, the plug and socket will not be able to be inserted into place, or the pins will be offset and deformed, affecting the electrical connection performance, causing jamming problems in the stage separation. Summary of the Invention

[0004] In view of the defects in the prior art, the purpose of the present invention is to provide a missile floating interstage connector and a separation method thereof.

[0005] According to the present invention, a missile floating interstage connector is provided, comprising a bracket and a booster, wherein a missile is provided on one side of the booster, the bracket is provided on the missile, and a socket is provided on the bracket, wherein a joint surface of the socket faces a side of the missile;

[0046] The present invention will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the scope of the present invention. These all fall within the scope of protection of the present invention.

[0047] Example 1

[0048] like Figure 1 As shown, on missile 1, two brackets 7 are secured to the missile near its right side with four screws 1 (8). Socket 3 is secured to the two brackets 7 with two screws 2 (9). The socket 3's mating surface faces the right side of the missile. Two locating pin holes 14 and a convex countersunk hole 15 are located on the right side of the missile. Booster 2 is provided with eight screw holes 16 and a waist-shaped hole 17. Two locating pins 13 and an explosive bolt 6 are secured to booster 2 through a pin-hole fit and threaded connection. The heads of the locating pins 13 and explosive bolt 6 extend beyond the left side of booster 2, and the two locating pins 13 mate with the two locating pin holes 14 on the missile. Plug 4 includes a free cable that floats near the left side of booster 2. A freely movable pull ring 18 is attached to the rear end of plug 4. With the right side of missile 1 adjacent to the left side of booster 2, plug 4 is extended from booster 2 and aligned with socket 3 before insertion, ensuring perfect coaxial alignment between the pins 21 in plug 4 and the sockets 22 in socket 3. At this time, the plug 4 and the socket 3 on the booster 2 and the missile 1 are in the plug-in position.

[0049] like Figure 2As shown, the two locating pins 13 on the booster 2 are inserted into the two locating pin holes 14 on the missile 1, and the right side of the missile 1 is aligned with the left side of the booster 2. At the same time, the head of the explosive bolt 6 extends into the convex countersunk hole 15 on the right side of the missile 1 and is tightened with the nut 11. At this time, the pull ring 18 on the plug 4 is directly above the waist-shaped hole 17 of the booster 2. The cover plate 5 is an L-shaped structure with a raised vertical rod 19 on its inner surface. The raised vertical rod 19 ends at a widened stop 20. The cover plate 5 is fixed to the booster 2 by screws 10. The raised vertical rod 19 on the cover plate 5 passes through the waist-shaped hole 17 of the booster 2 and the pull ring 18 of the plug 4. The widened stop 20 on the cover plate 5 prevents the pull ring 18 on the plug 4 from sliding off the raised vertical rod 19 of the cover plate 5. At this point, the booster 2 and the missile 1 are fully assembled.

[0050] like Figure 3 As shown, when the explosive bolt 6 detonates, the remaining head 12 of the explosive bolt detaches from the explosive bolt 6, impacting and pushing the missile 1 forward, simultaneously driving the socket 3 to move. The plug 4, under the engagement force of the socket 3, moves synchronously until the inner wall of the pull ring 18 on the plug 4 contacts the raised post 19 on the cover plate 5. Then, under the stopper action of the widened stopper 20 on the raised post 19, the plug 4 overcomes the engagement force with the socket 3 and separates from the socket 3. At this point, the interstage connector of the booster 2 and missile 1 is separated.

[0051] Working principle:

[0052] The right side of the missile 1 is adjacent to the left side of the booster 2. The plug 4 is extended out of the booster 2 and aligned with the socket 3 before being plugged in, ensuring that the pin 21 in the plug 4 and the hole 22 in the socket 3 are completely coaxially aligned.

[0053] The two locating pins 13 on the booster 2 are inserted into the two locating pin holes 14 on the missile 1, and the right side of the missile 1 fits into the left side of the booster 2. At the same time, the head of the explosive bolt 6 extends into the convex countersunk hole 15 on the right side of the missile 1 and is tightened with a nut 11.

[0054] When the explosive bolt 6 detonates, the remaining head 12 of the explosive bolt detaches from the explosive bolt 6, impacts and pushes the missile 1 forward, and at the same time drives the socket 3 to move, and the plug 4 moves synchronously under the action of the engagement force of the socket 3, until the inner wall of the pull ring 18 on the plug 4 contacts the raised vertical rod 19 on the cover plate 5, and then under the stopping action of the widened stop block 20 on the raised vertical rod 19, the plug 4 overcomes the engagement force with the socket 3, and the plug 4 is separated from the socket 3.
