Description
Technical field
The utility model is related to a kind of sleeve pipe, more particularly to a kind of to provide reinforcement machine at long length loosely shielded optical cable stripping
Tool intensity and sealing protection and the buckle-type heat-shrinkable T bush that can be installed at an arbitrary position.
Background technology
Loosely shielded optical cable is that a kind of outside has Loose tube to protect, there is multi-core fiber inside and a kind of light filled with liquid fat
Cable.In fiber optic communication and sensory field of optic fibre, long length loosely shielded optical cable plays a part of signal transmission and builds multiplexed light, leads to
Often, it is necessary to certain point in the middle of great-length cable takes out certain root optical fiber, the Loose tube stripping outside loosely shielded optical cable must now be come
The optical fiber that picking needs, to strengthen the mechanical strength at stripping, prevents loosely shielded optical cable internal liquid grease to be largely lost in, at stripping
Must be effectively protected.
Existing method is typically to cover upper plain cylindrical form heat-shrinkable T bush one by one from the two ends of long length loosely shielded optical cable and move
Pyrocondensation is carried out to corresponding position, the shortcoming of this mode is：1. when loosely shielded optical cable length is very long, plain cylindrical form heat is inserted in
Heat-Shrinkable Tubings are wasted time and energy, and are easy to the situation for leakage set or many sets occur；2. once needing in the centre of long length loosely shielded optical cable
When place increases stripping mouthful or repairs certain stripping mouthful, increase plain cylindrical form heat-shrinkable T bush and operationally bother very much, and deposit
Damaging the risk of other optics.
Utility model content
Technical problem to be solved in the utility model is to provide one kind can be strong to increase machinery at loosely shielded optical cable stripping
Degree, moreover it is possible to prevent loosely shielded optical cable internal liquid grease to be largely lost in and can install or replace in the optional position of long length loosely shielded optical cable
The buckle-type heat-shrinkable T bush for loosely shielded optical cable for changing.
In order to solve the above-mentioned technical problem, the buckle-type heat-shrinkable T bush for loosely shielded optical cable that the utility model is provided, bag
Square heat shrinking sheet is included, and is located at described square heat shrinking sheet with respect to two the spill card sealings and convex buckle closure part on side, it is described
Spill card sealing recess it is corresponding with the convex portion of described convex buckle closure part fasten after formed protection loosely shielded optical cable thermal shrinkable sleeve
Pipe.
Described one layer of PUR of uniform thickness of the coating of square heat shrinking sheet internal layer or bonding, PUR is in certain pyrocondensation temperature
Can be completely melt under degree.
The material of described square heat shrinking sheet is PVC, ABS, EVA, PET or silica gel.
Described spill card sealing and the material of described convex buckle closure part are PVC, ABS, EVA, PET or silica gel.
The recess of described spill card sealing is mutually matched in shape, quantity with the convex portion of described convex buckle closure part and buckles
Close.
Described square heat shrinking sheet, spill card sealing and convex buckle closure part are integrally formed.
Described square heat shrinking sheet and described spill card sealing, described square heat shrinking sheet and described convex buckle closure part
Fixed by hot pressing or technique for sticking.
Described spill card sealing is a rectangular recess, and four angles of described rectangular recess are fillet, and described is convex
Shape buckle closure part is a rectangular lip, and four angles of rectangular lip are fillet.
Described spill card sealing is the recess of multiple rectangles or ellipse, and described convex buckle closure part is recessed with described
Multiple rectangles or oval protrusion that shape card sealing matches.
Using the buckle-type heat-shrinkable T bush for loosely shielded optical cable of above-mentioned technical proposal, the recess and convex of spill card sealing
The convex portion of buckle closure part is fastened by dimensional fits, firm after fastening, without clear gap.The recess of spill card sealing and convex buckle closure
The buckle-type heat-shrinkable T bush internal diameter size that the convex portion of part is formed after fastening with square heat shrinking sheet matches the loosely shielded optical cable of all size.
The invention has the advantages that：Simple structure, easy to use, material is easy to get, applied widely；Not only can be with
It is prior to increase mechanical strength at loosely shielded optical cable stripping, moreover it is possible to prevent a large amount of losses of loosely shielded optical cable internal liquid grease
Can be to install or replace in the optional position of long length loosely shielded optical cable.
In sum, the present invention is that one kind can be to increase mechanical strength at loosely shielded optical cable stripping, moreover it is possible to prevent Song Taoguang
A large amount of losses of cable internal liquid grease and can long length loosely shielded optical cable optional position install or replace for Song Taoguang
The buckle-type heat-shrinkable T bush of cable.
