Abstract

The invention relates to a split crimping MPO plug, which includes an outer shell, a pin part, a spring, a limit seat, a crimping sleeve and a tail sheath. The front housing on the tensile element on the outer periphery of the rear end housing of the seat and the rear housing crimped on the optical cable, the front end of the rear housing of the crimping sleeve is connected with a connection that can move axially in the rear end housing of the limit seat The connecting piece is inserted into the rear end shell of the limit seat and locked and positioned by the locking mechanism; the front shell and the rear shell of the crimping sleeve are detachable after the locking mechanism is unlocked, and the optical fiber is not stressed when the MPO plug is assembled and disassembled . The split-type crimping sleeve of the present invention is locked by a locking mechanism and anti-rotation by a anti-rotation mechanism. There is no need to disassemble the crimping sleeve and the limit seat when repairing and disassembling, and the optical fiber is not stressed during the entire assembly and disassembly process, and the optical fiber will not be damaged. Twist to facilitate rework grinding work and avoid damage to the fiber during handling.

Description

technical field

[0001] The invention relates to the technical field of optical fiber connectors, in particular to a split crimping MPO plug. Background technique

[0002] More and more MPO plugs are used in optical communication systems. Conventional MPO plugs are used in indoor environments, and some equipment manufacturers add protective shells to MPO plugs to apply them in outdoor environments. In order to increase protective shells, It is necessary to exert a large crushing force on the optical cable at the end of the plug, then it is necessary to increase the outer diameter of the optical cable to adjust the optical cable structure and strengthen the compression resistance of the optical cable. At this time, a large-diameter MPO plug is required.

[0003] Due to the large diameter of the optical cable, the one-piece limit seat cannot be retracted to the optical cable, so the limit seat is made into a two-body structure, such as figure 1 As shown, when assembling, the c...
