Specific embodiment
The present invention will be further described with reference to the accompanying drawings and detailed description.
As shown in Fig. 1 to Fig. 5, a kind of fiber box, including
Cabinet 1 and can the chamber door that opens or closes of opposite case, the wall box be equipped with air outlet 11 and it is several into
Air port 12, air outlet are equipped with filtering grenadine 13, and air inlet is equipped with filtering grenadine,；
In the intracorporal blast pipe 2 of case, the blast pipe and air inlet are corresponded for several settings, blast pipe input end with it is right
The air inlet connection answered, blast pipe is interior to be equipped with air intake blower fan 21, and blast pipe is equipped with air inlet check valve；
It is arranged in the intracorporal main air hose 3 of case, blast pipe outlet end is connected to main air hose one end；
In the intracorporal fibre distribution frame 4 of case, fibre distribution frame is equipped with several for grafting fibre-optical splice for several settings
Jack-plug socket 41；
Several logical cable architectures, logical cable architecture include the threading hole 51 being arranged on wall box and for blocking threading hole
Resilient plug 52.
The cabinet be in rectangular cylindrical, in a blast pipe: enter the wind check valve can by direction be by blast pipe into
Mouth end to blast pipe outlet end is entered the wind at check valve at blast pipe outlet end.
Filtering grenadine can prevent dust from entering cabinet, to protect to box house, avoid internal dust accumulation and lead
The problems such as fever aggravation of cause, unsmooth, acceleration of radiating detract component life.Air intake blower fan in each blast pipe can be to case
Internal portion carries out air feed, and with benefit heat dissipation, and air intake blower fan does not need to be all turned at any time, can effectively energy conservation.Cabinet internal wiring is inserted
When mouthful utilization rate is higher, whole calorific value is larger, several air intake blower fans can be opened more, increase air quantity, line jack is inscribed in cabinet
When utilization rate is lower, whole calorific value is smaller, several air intake blower fans can be opened less, can ensure proper heat reduction.Resilient plug
The threading hole not used can be sealed, dust, impurity is avoided to enter cabinet.When needing to access, drawing optical fiber, need which is used
A jack-plug socket just takes out the resilient plug on the threading hole for belonging to a logical cable architecture with the jack-plug socket simultaneously, optical fiber is allowed to wear
The string holes is crossed, and being plugged on the jack-plug socket can common plug connectors such as (connection-peg on optical fiber head be) crystal heads.
The logical cable architecture further includes that the closure gasket groove being arranged in threading hole and the inflation being arranged in closure gasket groove are close
Seal 53, cabinet is interior to protect structure with logical cable architecture equipped with several correspondingly, and protection structure includes protecting cylinder body 6 and protecting
Shield cylinder body is slidingly sealed the first piston 61 of cooperation and is slidingly sealed the second piston 62 of cooperation with protection cylinder body；
In corresponding logical cable architecture and protection structure: being connected between first piston and second piston by intermediate piston bar 63
It connects, first piston and second piston will protect cylinder interior to be separated into the venting cavity 6a, adapter cavity 6b and inflatable chamber being sequentially arranged
6c, inflatable chamber is interior to be equipped with return-air spring 64, and return-air spring one end connects second piston, return-air spring other end connection protection cylinder
Body, venting cavity are connected to by snorkel 65 with main air hose, and inflatable chamber is connected to by gas tube 66 with gas-flow closure circle, and main air hose is another
It is closed at one end；
It is equipped in cabinet several with the one-to-one air nozzle 7 of jack-plug socket, the jet direction of air nozzle is towards corresponding
Jack-plug socket, air nozzle and protection structure correspond, and in corresponding air nozzle and protection structure: adapter cavity passes through coupling tube
67 are connected to air nozzle.
The first piston glide direction is vertical, and second piston glide direction is vertical, and first piston is in second piston
Side, venting cavity, adapter cavity and inflatable chamber are from top to bottom sequentially distributed, and return-air axle of spring is vertical.
In corresponding logical cable architecture and protection structure: the snorkel arranges that snorkel is rubber tube, threading hole vertically
Axis horizontal, resilient plug pass through threading hole, and resilient plug one end is in outside threading hole, and resilient plug one end is in cabinet, resilient plug
The intracorporal one end of case is in equipped with the horizontal pressing plate 521 for squeezing snorkel.
The protection cylinder body is equipped with hard fixing seat 68, and hard fixing seat contacts snorkel lateral wall, in corresponding logical knot
In structure and protection structure: in the horizontal direction, rubber tube is between horizontal pressing plate and hard fixing seat.
It, may not be able to (optical fiber thickness be different, optical fiber for perfect fitting between threading hole hole wall after optical fiber passes through threading hole
Section is not necessarily caused by the factors such as circle), it cannot so ensure the dust-obstructing efficiency at threading hole.
And in the present embodiment, by taking visual angle in Fig. 3 as an example, initially, first piston position is higher than coupling tube and adapter cavity connects
Logical to locate, after main duct ventilation (blast pipe where air intake blower fan in work is to main air hose air feed), air-flow enters through snorkel
Venting cavity drives first piston, intermediate piston bar and second piston to move down together, presses inflation chamber air and enters through gas tube
Gas-flow closure circle, gas-flow closure circle are sufficiently heaved to be close to optical fiber, have ensured the dust-obstructing efficiency at threading hole, same with this
When, due to moving down, first piston position is lower than coupling tube and adapter cavity connectivity part, and coupling tube is just connected with venting cavity at this time,
Main air hose interior air-flow can reach at corresponding air nozzle through snorkel, venting cavity and coupling tube, and air nozzle can be to corresponding
(grafting optical fiber) jack-plug socket at radiate.It was previously noted, once grafting optical fiber (connects on jack-plug socket
Head), it is exactly that main heating position so the scheme of the present embodiment can targetedly radiate directly avoids heating part
Position heat accumulation.
Also, the logical cable architecture that does not use and lead in the corresponding protection structure of cable architecture with this: threading hole is by resilient plug
It blocks, snorkel (rubber tube) is tightly pressed against in hard fixing seat by the horizontal pressing plate on resilient plug, and snorkel is to block, main wind
Pipe interior air-flow will not lead to cable architecture air feed (also calm at air nozzle) to this, will not cause the movement of structure.So heat transmission gas
Stream will not be wasted in and on not used jack-plug socket, will not enter gas-flow closure circle to ensure the dust-obstructing efficiency at threading hole
(resilient plug clogs threading hole, at this time without using arrive gas-flow closure circle).
It is to sum up sayed, the logical cable architecture not used can automatically cut off gas supply, can avoid the waste of air-flow, sufficiently energy conservation.And
Using the logical cable architecture arrived, gas supply access can be automatically opened, sealing dust-obstructing efficiency is ensured using air-flow, ensures specific aim heat dissipation
Effect.Also, when as was noted, cabinet is inscribed that line jack utilization rate is higher, whole calorific value is larger, can open more it is several into
Wind blower, increases air quantity, when cabinet is inscribed that line jack utilization rate is lower, whole calorific value is smaller, can open several air inlets less
Blower can ensure proper heat reduction.The present invention can targetedly radiate, and energy flexible modulation, guarantee heat dissipation effect,
The service life that can ensure structure, makes full use of air-flow, avoids wasting, energy-efficient.
