A kind of fiber coupler terminal unit case, it comprises casing, be enclosed within the drawer in the casing, wire jumper mechanism and be fixed on shunt on the drawer-bottom board inwall, it is characterized in that: the appropriate location is provided with position-limit mechanism between casing and drawer.
Described wire jumper mechanism is fixed on the drawer inwall base plate.
Described position-limit mechanism is between shunt and wire jumper mechanism.
Described position-limit mechanism comprises spacing catch that is positioned on the casing and the spacing blend stop that is positioned on the drawer side.
Described wire jumper mechanism comprises wire jumper head, adapter and installation panel, and the wire jumper head links to each other with the adapter two ends, and it is fixed on the installation panel.
Described wire jumper mechanism also comprises the adapter bar, and adapter bar and installation panel are affixed, and adapter is contained on the adapter bar.
On described drawer-bottom board, the outside of position-limit mechanism is provided with wire installation.
Described wire installation is made up of 7 font wire-blocking boards and fixed head, and 7 font wire-blocking boards are fixed on the fixed head.
The arc wire guide plate that the band blend stop is arranged on the left and right sides of a drawer bottom surface side relative with shunt.
The structure of described adapter bar is: be evenly equipped with a plurality of adapter draw-in grooves on fixed strip, at the two ends of fixed strip a clip arranged respectively, be used for fixed strip is fixed on installation panel.
The utlity model has following advantage: owing to adopted the drawer stop means, can prevent to pull out in the lump fiber coupler (shunt), increase maloperation and may make fiber coupler be subjected to accidental damage; Owing to adopted the structure of wire installation, front bezels for drawers, arc wire guide plate, transition radius, the wire jumper that can control wire jumper is difficult for going offline and can avoids mutual winding, also avoids the outside wire jumper directly to expose simultaneously, avoids being subjected to unexpected injury; Use plug-in adapter bar, be applicable to the general installation of multiple adapter (as FC, SC, LC type adapter), need not screw retention, be more convenient for the installation and the replacing of adapter.It is safer, simpler and easy that this fiber coupler terminal unit case has operation, behind the line winder of cancellation conventional arrangement, and its casing littler advantage that takes up room.
