The installing port 22 of orchestration installation, installing port 22 are removedly equipped with the integrative installation technology for two kinds of common insertings of optical adapter
Slot 7, mounting groove 7 include vertically disposed first mounting groove 71, the second mounting groove 71 and the first mounting groove 71 of limitation and the
There are upper and lower two rows to be fitted for SC for the anti-tampering part that adjacent optical adapter interferes with each other between two mounting grooves 72, the first mounting groove 71
The first jack 711 that orchestration plugs, the second mounting groove 72 also have the second jack that upper and lower two row supplies LC adapters to plug
721.First jack is in the square hole being adapted to SC adapter shells, and the second jack 721 is in the horizontal stroke being adapted to LC adapter shells
Male ports are put, the square hole hole wall adjacent with horizontal male ports locally connects.Wherein, the square hole hole adjacent with male ports
The second hole wall 7112 that wall is divided into the first hole wall 7111 extended straight down and extends straight up, the first hole wall
7111 are oppositely arranged with the second hole wall 7112.The hole walls 7211 of first hole wall 7111 and horizontal male ports, the second hole wall 7112 with
The hole wall 7211 of horizontal male ports is connected by the connection wall 8 of arc-shaped shape, connection wall 8 from left to right gradually it is bending to the right with
Form anti-tampering part.
For the present embodiment by taking 9 integrative installation technology slots as an example, integrative installation technology slot uses two kinds of SC adapters and LC adapters
Inserting can significantly improve the degree of modularity of optical branching device, and if SC adapters are one point 8, upper and lower two are then one point 16, LC
Adapter is also one point 8, and upper and lower two are then one point 16, and capacity improves 4 times, can not only compared to the dilatation of single adapter
Significantly improve the degree of modularity of optical branching device, moreover it is possible to simplify the installation of optical branching device and dilatation program, have effectively achieved with
The mode of combination connects, and the adapter 20 and its quantity of SC, LC can be flexibly selected according to actual conditions.
In addition, substrate 21 is outward extended with the first plate body 3 and the second plate body 4, the first plate body 3 in the both sides of installing port 22
Be provided with the through-hole 6 installed for connector 5 on the second plate body 4, optical fiber terminal box is MPO termination boxes in the present embodiment, is connected
Fitting 5 includes plug 51 and the pullover 52 that can be set on the plug 51, and wherein the end of plug 51, which has, is more than through-hole 6
End cap 511, and the tail portion evagination of plug 51 has a plush copper 512, and pullover 52 includes the base portion that 51 tail portion of plug can be supplied to pass through
521, the peripheral surface of the base portion 521, which has, to extend outwardly and spaced three elastic card bases 522, the end of elastic card base 522
Portion is gradually to inside contracting to form pagoda shape, and in a state that the base portion 521 of pullover 52 is inserted in plug 51, elastic card base 522 can press
Tightly in plush copper 512 plug 51 is fixed on through-hole 6.In order to preferably position the base portion 521 of pullover 52 and elastic card base
522, the tail portion of plug 51 is radially recessed respectively inwards the first of the base portion 521 that can supply pullover 52 and the elastic positioning of card base 522
Recessed 513 and second recessed circle 514 of circle, the outer diameter of the first recessed circle 513 are more than the second recessed circle 514, and wherein base portion 521 can be resisted against the
On one recessed circle 513 and elastic card base 522 can limit that recessed to enclose 514 interior and moved relative to plush copper 512 second.
Since the end of elastic card base 522 is gradually to inside contracting to form pagoda shape, just with outer diameter relatively small second
Recessed circle 514 is adapted, and base portion 521 can be resisted against on the recessed circle 513 of outer diameter relatively large first, passes through the first recessed circle 513
Pullover 52 is positioned jointly with the second recessed circle 514, when plug 51 is inserted into the through-hole 6 of the first plate body 3 or the second plate body 4, end cap
511 can seal the through-hole 6, and in the state of 52 locking-type plug 51 of pullover, it is opposite that the base portion 521 of pullover 52 can be resisted against outer diameter
On larger first recessed circle 513 and each elastic card base 522 is limited in the second recessed circle 514 in which can inside contract and with 512 phase of plush copper
It supports, when needing to extract plug 51 from pullover 52, it is only necessary to by the elastic card base 522 of pullover 52 to the direction of plush copper 512
It is mobile, so as to which each elastic card base 522 can be expanded outwardly along plush copper 512, so that the base portion 521 of pullover 52 is with respect to the first flange collar
It is moved outside phase, so as to which plug 51 can be extracted from pullover 52.
It is cumbersome when omitting screw nut installation in this way, during installation, it is only necessary to which plug 51 will be first inserted into the first plate body 3
Or the second through-hole 6 on plate body 4, using the end of plug 51 there is the end cap 511 more than through-hole 6 to cover through-hole 6, then cover
Upper pullover 52 will be gradually inserted with forming the grasping force of pagoda shape formation to inside contracting using the end of the elastic card base 522 of pullover 52
The fastening of first 51 plush copper 512, during dismounting, it is only necessary to move elastic card base 522 relative to plush copper 512, so as to each elastic card base
522 can expand outwardly along plush copper 512, so as to which plug 51 can be extracted from pullover 52.
