Embodiment 1

[0030] First, refer to figure 1 and figure 2 Embodiments of the MPO connector of the present invention will be described. figure 1 is a view of the MPO connector 100 of this embodiment seen from the surface side, figure 2 It is a figure seen from the back side. In these figures, the configuration is such that the multi-core optical fiber 105 exposed on the front side of the MPO connector 100 is arranged in the MT ferrule 110, the MT ferrule 110 is covered by the inner shell 120, and the inner shell 120 is further wrapped by the outer shell 130. cover. The round cable 140 connected to the back side of the MPO connector 100 is covered by the MPO protective cover 150, and the optical fiber in the round cable 140 passes through the inner shell 120 and the MT ferrule 110, and is exposed as a multi-core optical fiber 105 . The inner shell 120 is exposed from the skirt portion 132 of the outer shell 130 on the round cable 140 side, and an elastic bush 160 is provided between...

Abstract

[Problem] To provide an optical connector and a push-pull tab that enable easy attachment and detachment of the optical connector to and from an optical adapter even for a narrow pitch in high-densitymounting. [Solution] When attaching a push-pull tab (200) to an MPO connector (100), an operator manually pinches a slide stopper (236) on a detachment bar (230) on the push-pull tab (200), allowinga round cable (140) to pass through openings (252, 262) so that the round cable (140) is inserted into grips (250, 260). Then, the operator pushes the detachment bar (230) toward the front. When attaching the MPO connector (100) to an MPO adapter (600), the operator manually pinches the detachment bar (230) on the push-pull tab 200 and pushes the detachment bar (230) into the MPO adapter (600). Conversely, when separating the MPO connector (100) from the MPO adapter (600), the operator manually pinches the slide stopper (236) on the detachment bar (230) to pull the slide stopper (236) toward the round cable (140).

Description

technical field [0001] The present invention relates to an optical connector and a push-pull (Japanese: プッシュプル・タブ), in particular to a multi-core optical fiber connector (hereinafter referred to as "MPO connector") capable of high-density installation at a narrow pitch and for A push-pull for attaching and detaching the connector. Background technique [0002] Conventional MPO (Multi-fiber Push-on) connectors include, for example, Figure 9 Round cables shown use MPO connectors. in the Figure 9 In the figure, the structure is as follows: the multi-core optical fiber 505 exposed on the front side of the MPO connector 500 is arranged in the MT (Mechanically Transferable: mechanical docking transmission) ferrule (Japanese: フェルール) 510, and the MT ferrule 510 is wrapped by the inner shell 520 The inner shell 520 is further covered by the outer shell 530 . The round cable 540 connected to the opposite side of the MPO connector 500 is covered by the MPO protective cover 550, and...
