The aobvious degree of modularity for improving optical branching device, moreover it is possible to which installation and the dilatation program for simplifying optical branching device have effectively achieved with group
The mode of conjunction 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 4,3 He of the first plate body in the both sides of installing port 22
The through-hole 6 installed for connector 5 is provided on second plate body 4, optical fiber terminal box is MPO termination boxes, connection in the present embodiment
Part 5 includes plug 51 and the pullover 52 that can be set on the plug 51, and wherein the end of plug 51 has more than through-hole 6
End cap 511, and the tail portion evagination of plug 51 has a plush copper 512, pullover 52 include can for the base portion 521 that 51 tail portion of plug passes through,
The peripheral surface of the base portion 521, which has, to extend outwardly and spaced three elasticity card bases 522, the end of elasticity card base 522 by
Gradually to inside contracting to form pagoda shape, in the state that the base portion 521 of pullover 52 is inserted in plug 51, elasticity card base 522 can be pressed on
Plug 51 to be fixed on through-hole 6 in plush copper 512.In order to preferably position the base portion 521 and elasticity card base 522 of pullover 52,
The tail portion of plug 51 is radially recessed respectively inwards the first recessed circle that can be positioned for the base portion 521 and elasticity card base 522 of pullover 52
513 and second it is recessed circle 514, first it is recessed circle 513 outer diameter be more than second it is recessed circle 514, wherein base portion 521 can be resisted against the first recessed circle
On 513 and elasticity card base 522 can limit in the second recessed circle 514 and the movement of opposite plush copper 512.
Since the end of elasticity 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 of outer diameter relatively large first 513, pass through the first 513 Hes of recessed circle
Second recessed circle 514 jointly positions pullover 52, 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 elasticity card base 522 is limited in the second recessed circle 514 and offsets with plush copper 512 in which can inside contract,
When needing to extract plug 51 from pullover 52, it is only necessary to move the elasticity card base 522 of pullover 52 to the direction of plush copper 512
It is dynamic, to which each elasticity card base 522 can be expanded outwardly along plush copper 512, to the opposite first flange collar phase of the base portion 521 of pullover 52
Outer shifting, to which plug 51 can be extracted from pullover 52.
It is cumbersome when omitting screw nut installation in this way, when installation, it is only necessary to first will plug 51 be 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 put on
Pullover 52, using the end of 52 elasticity card base 522 of pullover gradually to inside contracting to form the grasping force that pagoda shape is formed with by plug
The fastening of 51 plush coppers 512, when dismounting, it is only necessary to move elasticity card base 522 relative to plush copper 512, to 522 meeting of each elasticity card base
It is expanded outwardly along plush copper 512, to which plug 51 can be extracted from pullover 52.
