During conjunction, matching fastener is by spacing for firm banking 8 inner side being fixed on end cap 6；The top of two firm bankings 8 is equipped with groove
22, it is embedded with land cable fixture 10a in a groove 22, in a groove 22, is embedded with sea cable fixture 10b, fixture self
For electric conductor, and and described cylinder 4 between insulation arrange, after each cable enters in cylinder 4, land cable fixture 10a is used for fixing land
Ground optical cable, sea cable fixture 10b is used for fixing submarine optical fiber cable, and specifically, land optical cable enters its steel wire reinforcement later in cylinder 4
Core is fixed on the cable fixture 10a of land, and in submarine optical fiber cable entrance cylinder 4, its armour fixation with steel wire later is at sea cable fixture 10b
On.
As shown in Figure 4, monitoring cable 1 has three groups of cable cores, respectively first group cable core 1a, second group of cable core 1b and the 3rd
Group cable core 1c, described monitoring cable 1 enters after in cylinder: its first group of cable core 1a is fixed on the cable fixture 10a of land, and it is the years old
Two cable core 1b are fixed on the cable fixture 10b of sea, its 3rd group of unsettled setting of cable core 1c；Described 3rd group of cable core 1c has each other
The first cable core 11c and the second cable core 12c of insulation setting.
Concrete, as it is shown on figure 3, described fixture is cylindrical shape structure, its both ends are equipped with fixing hole, are respectively
First fixing hole 16a and the second fixing hole 16b, its axial middle part is provided with for passing land optical cable or submarine optical fiber cable
The first through hole 18, described first fixing hole 16a and the first through hole 18 connect, and described first fixing hole 16a coordinates fastening
Part is locked and passes the conductor part of both the land optical cable of described first through hole 18 or submarine optical fiber cable；First fixing hole
The securing member of 16a preferably employs stainless steel screw.Land cable fixture 10a and sea cable fixture 10b, originally as conductor, has conduction
Property, the current-carrying part of both submarine optical fiber cable or land optical cable is all electrically connected with fixture, and the monitoring cable of the application enters
After entering in cylinder 4, its first group of cable core 1a is fixed on the second fixing hole 16b of land cable fixture 10a, its second group of cable core
1b is fixed on the second fixing hole 16b of sea cable fixture 10b, and the second fixing hole 16b is screw hole, first group of cable core 1a and the
The conductor part of two groups of cable core 1b is tied up on the screw of screw hole, and after so connecting, first group of cable core 10a is formed with land optical cable
It is electrically connected with, for gathering the electrical property signal of the land optical cable entered in cylinder 4；Second group of cable core 10b and submarine optical fiber cable shape
Become to be electrically connected with, for gathering the electrical property signal of the submarine optical fiber cable entered in cylinder 4.
After external electrical performance test system building is good: during the sealing property of 1. test splice box, the first cable core 11c and
Two cable core 12c form the first binding post and second binding post of external test system respectively, by the first binding post and
Two binding posts are electrically connected in test system formation test loop, the electrical insulating property of test splice box.
When 2. testing the electrical property of land optical cable, first group of cable core 1a and ground terminal 3 form external test system respectively
The first binding post and the second binding post, the first binding post and the second binding post are electrically connected in test system

So, can accomplish just can be with the sealing property of butt joint line box, land light on the premise of not dismounting joint box
The electrical property of cable, the electrical property of submarine optical fiber cable are monitored in real time, and the improvement of slight structure brings traditional jointing box impossible real
Existing function.
Based on said structure, the installation process of inventive joint box is:
The termination of submarine optical fiber cable to be continued, land optical cable and monitoring cable is made adaptive pre-treatment: submarine optical fiber cable needs
Segmentation is removed protective layer, is exposed PE layer, armour steel wire floor and stainless steel tube respectively successively, and wherein armour steel wire floor only stays a steel
Silk；Land optical cable needs to remove protective layer, exposes steel wire strengthening core；Monitoring cable needs to remove protective layer, exposes wire；
Being fixed on end cap 6 by firm banking 8, that distributes every cable enters cable mouth 2, and each cable processed all sequentially passes through cable
Sealing locking member 30, gasket seal 24, taper cable sealing ring 26, end cap 6, firm banking 8, fixture 10 is fixed on firm banking
On 8, the armour steel wire of submarine optical fiber cable, land optical cable steel wire strengthening core through the first corresponding through hole 18, stretch steel wire or
Person's steel wire strengthening core also tightens the securing member of fixing hole 16, blocks steel wire or steel wire strengthening core prevents from loosening, monitoring cable
A piece wire is connected with the securing member of fixing hole 16.
Install the most successively and lead fine plate 34, fine tray salver 36, complete fused fiber splice, and dish enters in fine tray salver 36, installs fine dish
The lid of box 36, puts in cylinder 4 by mounted basetray 32, locks each cable subsequently and seals locking member 30, completes joint
The integral installation of box.
Embodiment two
As it is shown in figure 5, the present embodiment provides a kind of method that rosette in embodiment one is carried out electrical property monitoring,
First cable core 11c and the second cable core 12c forms the first binding post and second binding post of external test system respectively, by
One binding post and the second binding post are electrically connected in test system formation test loop, test electrical insulating property, how to survey
Test result is great resistance, then judge that the first cable core and the second cable core electrical insulation capability are good, the internal anhydrous infiltration of connector box,
Favorable sealing property；If test result is less resistance value, then judge the first cable core and the second cable core electrical insulation capability not
Good and conducting, have water to penetrate into inside connector box, sealing property is bad.
Under normal circumstances, the first cable core 11c and the second cable core 12c in cylinder 4 are arranged for insulation, are consequently formed
