Abstract
The utility model relates to a rope cutting device, in particular to fuse ware. A microminiature fuse ware, it includes: support (6), guide arm (7), wire (4), collets (8) and resistance wire (9), the utility model is suitable for a spacecraft space deployment mechanism, in the transmission shape attitude, space deployment mechanism compresses tightly on the spacecraft through the rope, and the back of entering the orbit is through right the utility model provides an electricity, the resistance wire generates heat and reaches the higher temperature on the fuse ware, and after the temperature was higher than the rope fusing point, the rope was cut off, and space deployment mechanism is released the back to expand by oneself to space release function has been accomplished. The utility model discloses low -cost, the envelope is little, light in weight, reliable operation.
Description
Technical field
This utility model relates to a kind of rope cutting-off device, particularly to a kind of fuse device.
Background technology
In spacecraft miniaturization, abroad occur in that weight only tens kilograms, Shuo Qianke, the even satellite less than a kilogram.Corresponding microminiature space development mechanism is occurred in that along with this micro-thermoelectric generator.Tradition large satellite space development mechanism adopts Fire load to realize unlocking in-orbit, and it is big that Fire load has size, and weight is big, has the feature of higher impact during work, it is impossible to meets microminiature spacecraft development mechanism and compresses the demand of release.
For meeting the space micro-thermoelectric generator development mechanism urgent needs to microminiature tripper, a kind of low cost of needs, envelope are little, lightweight, reliable operation, power consumption microminiature tripper little, shock-free, cannot be only used for the application that tiny spacecraft space development mechanism unlocks in-orbit, and can possess the ability substituting tradition firer's tripper.
Summary of the invention
The purpose of this utility model is: for meet microminiature spacecraft development mechanism to tripper low cost, envelope little, lightweight, reliable operation, power consumption needs little, shock-free, it is provided that a kind of microminiature fuse device.
The technical solution of the utility model is: a kind of microminiature fuse device, it includes: bearing, guide rod, wire, collets and resistance wire；
The outer surface of guide rod is provided with guide groove, and guide rod slides in bearing, and bearing is provided with location screw, and location screw coordinates the rotation of restriction guide rod with the guide groove of guide rod；
The afterbody of guide rod is socketed with spring, and is coordinated spring compression between fixing screw and bearing with guide rod inner thread by fixing screw；
The head of guide rod connects collets by housing screw is fixing；
Wire, through guide rod, realizes connecting with the resistance wire at collets place.
Work process of the present utility model is: spacecraft deployable mechanism is pressed on spacecraft sidewall at emission state by compressing rope, compresses rope through the region fuse device resistance wire and collets, and resistance wire is abutted against on compression rope by spring.When needs work, resistance wire is powered thus producing higher temperature, when temperature is higher than the fusing point of compression rope, namely it is blown, meanwhile, guide rod drives resistance wire along bearing sliding thus cutting off further and compressing rope under the action of the spring, thus completing the release compressing rope.
This utility model low cost, envelope are little, lightweight, reliable operation, power consumption are little, nothing is impacted, and is verified on skin receives solar wing.

Fig. 2 is view during utility model works；
Fig. 3 be utility model works complete time structural representation.
Detailed description of the invention
Referring to accompanying drawing 1, a kind of microminiature fuse device, it includes: bearing 6, guide rod 7, wire 4, collets 8 and resistance wire 9；
The outer surface of guide rod 7 is provided with guide groove, and guide rod 7 slides in bearing 6, and bearing 6 is provided with location screw 2, and location screw 2 coordinates the rotation of restriction guide rod 7 with the guide groove of guide rod 7；
The afterbody of guide rod 7 is socketed with spring 5, and is coordinated with guide rod 7 inner thread by fixing screw 1 and be pressed between fixing screw 1 and bearing 6 by spring 5；
The head of guide rod 7 connects collets 8 by housing screw 3 is fixing；
Wire 4, through guide rod 7, realizes connecting with the resistance wire 9 at collets 8 place.
Referring to accompanying drawing 2,3, fuse device is fixed on bearing 6 on spacecraft by installation screw in use, compress rope 10 traverse resistance wire 9, now spring 5 is in compressive state, when needs work, by wire 4, resistance wire 9 being powered thus producing higher temperature, when temperature is higher than the fusing point of compression rope 10, being namely blown；In the process compressing rope 10 fusing, guide rod 7 is under the effect of spring 5, and rearward movement, drive resistance wire cuts off compression rope 10 further, thus completing the release of the space development mechanism that compacted rope 10 compresses.
