Specific embodiment
A kind of cable splice closure, including the box shell being made of upper box shell 1 and lower box shell 2, box shell has a length
Structure is fixed between upper box shell 1 and lower box shell 2 by hexagon socket head cap screw and nut cooperation, and one end of the box shell opens up
There is offering inside and outside connection box shell into cable hole 3, the other end to go out cable hole 4, the peace of box enclosure interior inside and outside connection box shell
Middle position in 1-1 of behaveing affectedly is fixed with fibre melting disc 5, fibre melting disc 5 and is provided with one piece of installation between cable hole 4 into cable hole 3 and out
Support plate 6 is installed and is fixed with optical cable retainer plate 7 and optical cable fixed column 8 in support plate 6, and the inside of upper box shell 1 and lower box shell 2 is equal
The seal groove 1-2 that a corral lives in installation cavity 1-1 is offered, is clamped between the seal groove 1-2 on upper box shell 1 and lower box shell 2
Sealing strip.Installing support plate 6 is the integral structure being moulded in inside lower box shell 2.
Cable hole 4 can have a length structure into cable hole 3 and out, and cable hole 4 can bend to a S into cable hole 3 and out
Type structure effectively can prevent optical cable from loosening.
It is integrally formed on the outer wall of the upper box shell 1 and lower box shell 2 to be uniformly molded with several reinforcing rib 2-1, reinforce
Muscle 2-1 and the length direction of box shell are vertically arranged.
Reinforcing rib 2-1 can play the role of two sides anticollision, impact, and buffering effect is significant.
It is described into cable hole 3 and out that the inside in cable hole 4 is arranged with elastic packing plug 3-1.
The both sides of the box shell are molded into continuous sawtooth dress protective edge structure 2-2, and sawtooth fills protective edge structure 2-2 can be with
The impact of the vertical forces of side is prevented, also plays the effect of buffering to a certain extent.
A crimping support plate 2-3, crimping support plate 2-3 Shang couple are stretched out in the both ends of the upper box shell 1 or lower box shell 2
It should be into cable hole 3 and 4 position of cable hole is screwed live conductor plate out.
The optical cable of box shell inner and outer ends can be fixed, and fixation effectively prevent optical cable to loosen.Inner end is solid by optical cable
Surely circle 7 and optical cable fixed column 8 are fixed, and optical cable fixed column 8 is a threaded post, and optical cable retainer plate 7 is screw-type gold cranse.
The cable splice closure Applicable temperature are as follows: -40~+65 DEG C, be applicable in atmospheric pressure are as follows: 70~106kPa.
The cable splice closure be suitable for aerial 48 cores and following optical cable, direct-burried, pipeline laying straight joint or point
Discrimination, which connects, to be used.
When installing and using the utility model:
1, site clearing determines the installation site of cable splice closure, arranges the optical cable that need to be installed.With spanner by interior hexagonal
Screw bolt and nut is backed out, and upper box shell 1 and lower box shell 2 are opened.
2, stripping fiber optic cables.Cable length has been measured, with device for peeling optical cable stripping 1.9m or so cable sheath, has been used in molten fibre
Coiling and welding on disk 5；50mm strengthening core is left, it can also corresponding length determines according to actual conditions.
3, fibre junction and installation fibre-optical splice protection heat-shrink tube and up-winding fiber.After optical fiber welding connects, when up-winding fiber,
First lap is coiled in the outermost of fibre melting disc 5, other fiber optic disc arounds is not less than at diameter the circle of 75mm, protects with fibre-optical splice
Heat-shrink tube is put into togerther in the fixing groove of fibre melting disc 5.
If you need to check whether sealing, following method can be used:
(100kPa or so) is inflated into box shell by the valve cock in elastic packing plug 3-1, is then immersed in water
Or suds are coated at sealing, see whether gas evolution.This method can check whether box shell seals.
