Description

MPO fiber connector

Technical Field

The utility model relates to a photoelectric device field especially relates to a MPO fiber connector.

Background

Along with the rapid development of communication such as big data and cloud computing, the requirement on network broadband is increased in a blowout mode, so that higher requirements are provided for optical fiber network density, and the traditional optical fiber wiring network cannot meet the development requirement increasingly. The MPO optical fiber connector is a multi-core multi-channel plug-in connector, which is widely applied to optoelectronic device products. The cable connector has the advantages of high connection density, stable and reliable performance, small volume, convenience in operation, easiness in wiring management and the like. The optical fiber connector with the guide pin hole is usually butted with a female optical fiber connector (NO PINS) with the guide pin hole and locked by using an adapter, and the physical contact of a matched multi-core inserting core is kept by utilizing the thrust of a compression spring, so that the multi-optical fiber interconnection of two optical cables is realized.

In the prior art, the MPO optical path butt joint is realized by means of precise butt joint of Pins and No Pins guide PIN holes through an MPO optical fiber connector, the Pins are metal pieces, the NO Pins are plastic pieces, the Pins and the MPO insertion core are matched with each other to repeatedly insert and pull, the Pins and the insertion core holes can rub, the NO Pins plastic holes can deform, precise butt joint cannot be guaranteed after the PIN holes deform, and product testing is abnormal.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the main technical problem who solves provides a MPO fiber connector, can promote the female first joint connector plug of MPO and use the number of times, prolongs the life of the female first joint connector plug of MPO.

In order to solve the technical problem, the utility model discloses a technical scheme be: the MPO optical fiber connector comprises an adapter for fixing a male optical fiber connector and a female optical fiber connector, wherein an installation through groove is formed in the adapter, guide grooves are formed in the inner walls of the two ends of the adapter, the MPO optical fiber connector is characterized in that the male optical fiber connector is provided with pins, pin holes are formed in the positions, corresponding to the pins, of the end head of the female optical fiber connector, and guide fillets are formed in the connection positions of the pin holes and the end face of the female optical fiber connector.

Furthermore, two side faces of the adapter are provided with locking channels.

Furthermore, the access ends of the male optical fiber connector and the female optical fiber connector are respectively provided with a convex key, and the convex keys are fixedly connected with the guide grooves of the adapter in a key groove matching manner.

Further, the installation through groove is provided with a flaring at the joint of the port of the adapter.

The utility model has the advantages that: the utility model discloses a MPO fiber connector through leading a fillet on NO PINS end lock pin, makes PINS and NO PINS end lock pin butt joint have a guide effect occasionally, can reduce NO PINS end lock pin hole wearing and tearing degree during the retransmission plug, improves the plug number of times.
