Specific embodiment
Below by drawings and Examples, the present invention is described in more detail.Illustrated by these, the features of the present invention
To be become more apparent from clearly with advantage.
Special word " exemplary " means " being used as example, embodiment or illustrative " herein.Here as " exemplary "
Illustrated any embodiment should not necessarily be construed as preferred or advantageous over other embodiments.Although each of embodiment is shown in the drawings
In terms of kind, but unless otherwise indicated, it is not necessary to accompanying drawing drawn to scale.
According to the OPGW cable splice closures that the present invention is provided, as shown in fig. 1, the connector box includes joint box main body 1,
The bottom of joint box main body 1 offers through hole 2, and external drying box 3 is provided with below the through hole 2；Described external dry
Drier is loaded with dry box 3；
The external drying box 3 includes top cover 31, base 32 and tubular side wall 33, as shown in Figure 2；Wherein, institute
It is transparent to state side wall such that it is able to observe directly drier from outside, and then knows the service condition of drier, and judgement is
It is no to need to change drier.
However, because OPGW cable splice closures need to be arranged on place higher, even if being also not easy to obtain by telescope
Enough to clearly image, so as to judging to increased difficulty, therefore, the drier is defined into the drying that changes colour in the present invention
Agent, after drier absorbs moisture, its color changes；The drier self-indicating can select IND90 color-change resins, so as to
Enough service conditions that drier is directly obtained from relatively more eye-catching color change, and then judge to change the time of drier.
Seal affixed between the external drying box 3 and joint box main body 1, its link position is provided with seal washer.
Such scheme is feasible in theory, but many problems are still present in real work needs solution to process, than
Such as, drier is not easily carried, and the operation for performing replacing drier in high-altitude is highly difficult, and drier is stored in external drying box
In, because external drying box has certain radial dimension, the color situation of the drier on the outside of it is can only see from the external world, no
Easily determine whether the drier inside external drying box fully works, change easily cause waste too early, changing too late again can
Cable splice closure interior humidity can be caused exceeded, in addition, external drying box needs have very big transparent region, but it is larger
Transparent region can reduce its structural strength, the bad design of construction of external drying box itself；Regarding to the issue above, have in the present invention
Body proposes following scheme：
Be additionally provided with connecting rod 34 inside the external drying box 3, the two ends of the connecting rod 34 respectively with top cover 31
It is connected with base 32, to cause that top cover 31 and base 32 clamp side wall 33 jointly, it is preferable that be provided with spiral shell in the connecting rod
Line, screwed hole is offered in the respective regions of top cover 31 and base 32 such that it is able to by screwing up the whole external drying box of consolidation,
And can quickly open the lid, change drier therein.
Preferably, screwed up by bolt between the external drying box and joint box main body 1, it is quick by removing after bolt
External drying box is changed, the purpose of quick-replaceable drier is reached by directly changing external drying box.
In one preferred embodiment, the recess 35 to lower recess is provided with the upper surface of the top cover 31,
The recess 35 is located at the lower section of through hole 2, so that the moisture being deposited from joint box main body 1 can be fed directly to
Temporarily stored in recess；
Further, offered on the recess 35 through the inlet opening 36 of top cover 31, recess 35 and external drying box
Inside connected by inlet opening 36 so that in recess store water entered into external drying box by inlet opening 36
Portion.
In one preferred embodiment, there is multiple the inlet opening 36, is distributed on around connecting rod 34, that is, in being located at
Heart district domain, contacts with the drier in the middle part of external drying box first from there into the moisture in external drying box, enables to
The drier in outside finally absorbs moisture discoloration in external drying box, so that, it is external when being seen by transparent windows/side standing motionless as if facing a wall
When drier in drying box changes colour, you can know that external drying box is substantially saturated for the absorption of moisture, it should set about changing
External drying box.
, wherein it is desired to the method for special instruction, connection top cover and base has a lot, the present invention is selected and is arranged on centre
The purpose that is attached of connecting rod 34 be not only only that its it is convenient dismantle, economic, convenience is also resided in and is arranged on external drying box
The connecting rod at middle part can also play a part of water conservancy diversion, and multiple inlet openings 36 are distributed on around connecting rod, are entered from inlet opening 36
Water can be flowed downward along connecting rod.
In one preferred embodiment, due to offering inlet opening on top cover, when carrying, transporting external drying box
Make it possible to drier string therein to go out, pollute and waste, therefore, preferably, the drier is in granular form, described
Internal diameter size of the particle diameter size of drier more than the inlet opening 36.
In one preferred embodiment, the bottom of the joint box main body 1 is in coniform, towards the place of through hole 2
Direction inclines, so that the condensed water in joint box main body 1 can sufficiently pass through inlet opening being flowed into external drying box.
In one preferred embodiment, a pair of Fiber splice trays 4 are internally provided with the joint box main body 1；
The half core of optical cable is carried on each Fiber splice tray 4.Support bar 5 is provided with the joint box main body, it is described
Fiber splice tray 4 is arranged on support bar 5, and the Fiber splice tray 4 includes housing, and the housing is coated on exposed optical fiber and connects
Head is outside, is used to protect the joint area of optical fiber；The Fiber splice tray 4 can have not only in the multiple of 2, such as three or
4, it is contemplated that device interior space is limited and the factor such as mounting process, sets what two Fiber splice trays 4 can be optimal
Using effect.
Above in association with preferred embodiment the present invention is described, but these implementation methods are only exemplary
, only play illustrative effect.On this basis, various replacements and improvement can be carried out to the present invention, these each fall within this
In the protection domain of invention.
