Description
Technical field
Hereinafter description is related to optical cable circuit, and more specifically, relates to divide the optical fiber with many cores
It is fitted on the optical cable terminal box in multiple subscribers' lines.
Background technology
Generally provide optical cable terminal box to connect, to separate or to arrange the optical cable of optical cable circuit.Typically
Using optic terminal cable box, optical cable is distributed to one or more subscribers' lines.By being routed in termination box
Many cores of optical cable among separate one or more core optical communication link distributed to one or more user's lines
Road.Each remaining core being not yet assigned to subscribers' line in termination box is routed on optical communication link, keeps optics simultaneously
The form of cable.That is, a part for optical cable receives on optical communication link in termination box, and optical cable
Some cores be then separated out by termination box, as subscribers' line.
This optical cable terminal box typically anchors on phone mast or indoor wall or outdoor wall, rather than is embedded in
Underground.In addition, this optical cable terminal box typically receives one or more optical adapters, adapter, cable etc., to protect
Protect the coupling part of optical fiber at scene and separate part.
In traditional optical cable terminal box, it is separately formed one or more routing holes；This makes to cut light
Optical fiber is incorporated in the inside of termination box fibre, so that optical cable is routed in termination box.Therefore, only requirement
Core is separated out to subscribers' line in termination box, and remaining core is then welded to respectively by single routing hole and is incorporated into
On the core of new optical cable in the inside of termination box.Optical cable extends to optical communication link.
But, no matter when installing terminal box, on the cutting core not being separated out and the core being fused to new optical cable
It is all inconvenient for the technician.In addition, when the core that technical staff's cutting is not separated out with welding, coupling part
At least some of to will suffer from junction loss be inevitable.
Disclose a kind of use on March 8th, 2010 in Korean Patent NO. 947,631 that Korean Intellectual Property Office registers
In the optical cable terminal box solving this problem.This termination box is configured to allow for optical cable and draws in the case of not being cut
Enter in termination box.In addition, this termination box allows only to cut the core of needs, and it is connected to corresponding use in cable box
On the circuit of family.Termination box has a pair of routing hole being located at vicinity each other and the communicating hole being interconnected on routing hole；Thus, light
Learn cable to be routed in termination box in the case of not being cut.
Even if in addition, though traditional optical cable terminal box allows in the situation not cutting the core of optical cable completely
Under optical cable is connected up, but typically should by communicating hole introduce optical cable before remove optical cable
Crust.This can lead to them to deform or impaired during core is incorporated in communicating hole.Additionally, to be connected by cooperation by pressure
Knot protective seal pipe is necessary, to provide waterproof action between optical cable and corresponding routing hole, this makes difficulty
To execute wiring operations.

Deng so that cable sleeve 155 can be deformed due to the external force temporarily it being applied, and can be in the case of being not applied to external force
Return to the shape of its original.
Slotted portion 157a of the deployable cable sleeve of technical staff 155, and cable sleeve 155 is assemblied in optics electricity
On cable, to encase the outer peripheral edge of optical cable 105.In order to optical cable 105 is fastened on housing 101, this electricity wherein
Cable sleeve pipe 155 is assemblied in the state on optical cable 155, cable sleeve 155 can be placed in the first reception groove each
On, and cover 103 can be connected on housing 101.Now, along the edge of each routing hole 117, can be by housing 101
A part for a part and cover 103 is inserted in each sealed groove 157b.Sealed groove 157b may be formed to have little
The width of each the thickness in housing 101 and cover 103；Thus, cable sleeve 155 can be with housing 101 and cover
103 are in close contact, when being inserted in sealed groove 157b with the part in a part for housing 101 and cover 103,
Sealing function is provided.
When cover 103, cover 103 is inserted in the state in sealed groove 157b and is connected on housing 101 wherein
When, fasten and determine projection 137b and can determine groove 137a and engage with fastening, and can be fastened with single screw tightly from the inner side of housing 101
Gu part 139.Now, cover 103 can shine following manner extruded cable sleeve pipe 155：Cable sleeve 155 is subject to a certain degree of
Oppress, and slotted portion 157a of cable sleeve 155 is hermetically closed.
As described above, the disclosure provides a kind of optic terminal box, the wherein wiring of this optical cable terminal box
Hole is configured to style of opening so that during termination box is arranged on optical communication link, optical cable can free status
In routing hole, or separate with routing hole.This makes it possible to do not cutting not separating among many cores of optical cable
Installing terminal box and optical cable in the case of core.Because not needing cutting and welding core during the process of installing terminal box,
So installation operation can be easily performed.
The creative optical cable terminal box constructing as described above can have by using being formed at shell
