Above-mentioned plug is prior art with the plenum system of balancing plug, and its concrete structure and the course of work refer to public affairs
It is on 01 01st, 2014, Publication No. 103486375A to open day《Gas path plug-in unit connector》Patent document, the patent
Patentee be Beijing Space lift-off technology research institute and China Academy of Launch Vehicle Technology.《Gas path plug-in combination connection
Device》In " balancing plug plug " and " socket " be exactly " plug " and " socket " in the present invention, therefore in the present invention
Plug 207 and the concrete structure and the course of work of balancing plug 6 repeat no more.
Redundancy ball lock type plug-in connector of the present invention, wherein the upper end of the socket is provided with clamping boss, the clamping
The outer wall of socket 601 below boss is provided with back-up ring 603, and the socket 601 is fixed by clamping boss and back-up ring 603 and set
On connector body 1.In addition to above-mentioned fixed form, the mode that socket 601 can also be threaded connection fixes the company of being located at
Connect on device body 1.Socket 601 is not limited to both the above mode with the fixed form of connector body 1, can also pass through it
He is fixed mode, and such as welding, rivet are fixed etc., as long as socket 601 can be fixed on connector body 1.
Redundancy ball lock type plug-in connector of the present invention, wherein the mode that the plug 207 is threaded connection is fixed and is located at
On jack body 201.Certainly, plug 207 can also be fixed on jack body 201 by way of setting boss and back-up ring.
Plug 207 is not limited to both the above mode with the fixed form of jack body 201, can also carry out by other means solid
It is fixed, such as welding, rivet are fixed etc., as long as plug 207 can be fixed on jack body 201.
Redundancy ball lock type plug-in connector of the present invention, wherein cylinder (not shown) is in series with the steel wire rope 3, institute
Cylinder is stated for being tensioned steel wire rope 3.
When redundancy ball lock type plug-in connector of the present invention is docked, redundancy bulb 506 has been installed in advance in ball lock 5 in lock
Tight state, dropping the axially-movable of movable sleeve 503, to release the second steel ball 507 radially spacing, then connector body 1 is inserted on arrow
Socket 2, after the insertion redundancy of ball lock ball head 203 bulb 506, movable sleeve 503 is resetted, effect of second steel ball 507 in convex platform
Under be pushed into the groove of ball lock ball head 203, achieve a butt joint, then locking nut 103 is screwed up with a wrench, connector body
The lower surface of 101 upper surface laminating jack body 201, that is, realize the locking of connector.During connector locking, plug 207 is inserted
To enter realized in balancing plug 6 sealing supply.When connector comes off, rocket takes off or cylinder action is tensioned on steel wire rope 3, and then drags
Dynamic trip lever 509 and the motion unblock of movable sleeve 503, it is radially spacing that movable sleeve 503 releases first the second steel ball 507, then unlocks the
One steel ball 505 is radially spacing, thus connector is separated under normal circumstances by redundancy bulb 506 with the unblock of ball lock ball head 203, if
Redundancy bulb 506 and the clamping stagnation of ball lock ball head 203, then separated by redundancy bulb 506 with the unblock of ball lock body 501, realizes redundancy
Unblock.Connector comes off separation after the unblock of ball lock 5.The ball lock unblock failure at two, connector can be locked in ball by steel wire rope 3
The weakening groove of the upper end of bulb 203 is forced to break separation.Lock and force to break three layers of measure by redundancy ball, improve connector and separate
Reliability, it is to avoid connector can not come off and drag bad rocket body and cause safety issue.
Process that the course of work of the present invention is divided into connector butt-joint locking process and unblock comes off.
Before connector docking, the state of connector body 1 is shown in that the state of socket 2 is shown in accompanying drawing 3 on accompanying drawing 2, arrow, before connector docking
And the process status that comes off is shown in accompanying drawing 6, connector butt-joint locking state is shown in accompanying drawing 1.
Connector butt-joint locking process：Redundancy bulb 506 is installed in advance in ball lock 5 in locking before connector docking
State, the locking nut 103 on connector body 1 is rotated counterclockwise, and ball lock 5 is spacing due to the circumference of bearing pin 502, is locked
Nut 103 by screw thread to driving front, after the axial sports limiting in connector body 101 of bearing pin 502, stretch completely by ball lock 5
Go out, now dropping the axially-movable of movable sleeve 503, to release the second steel ball 507 radially spacing, then connector body 1 is inserted on arrow
Socket 2, after the insertion redundancy of ball lock ball head 203 bulb 506, movable sleeve 503 is resetted, and the second steel ball 507 is pushed into ball lock ball head
In 203 groove, achieve a butt joint, then locking nut 103 screws up with a wrench, the upper surface of connector body 101 laminating socket
The lower surface of body 201, in the now insertion of plug 207 balancing plug 6, balancing plug 6 is docked in place, and connector realizes locking.
Connector unlocks the process that comes off：Move upwards when rocket takes off, steel wire rope 3 is tensioned, so drop trip lever 509,
Bearing pin 502 drives movable sleeve 503 to move downward unblock, and connector comes off.Movable sleeve 503 releases first the second steel ball 507 radially
It is spacing, then to release the first steel ball 505 radially spacing, thus connector first passes through under normal circumstances redundancy bulb 506 and ball lock ball
203 unblocks are separated, if redundancy bulb 506 and the clamping stagnation of ball lock ball head 203, are solved by redundancy bulb 506 with ball lock body 501
Lock is separated, and realizes separate mode of the normal release in combination with redundancy unblock.Solve at the second steel ball 507, the first steel ball 505
During lock failure, force to break separation at the weakening groove that connector passes through the upper end of ball lock ball head 203.
The present invention carries the dependable performance that comes off through performance test checking, connector sealing and supply band, simple and compact for structure,
It is easy to operate.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the model of the present invention
Enclose and be defined, on the premise of without departing from design spirit of the present invention, technical side of the those of ordinary skill in the art to the present invention
Various modifications and improvement that case is made, all should fall into the protection domain of claims of the present invention determination.
