Description

A kind of MPO fiber-optical socket

Technical field

The utility model relates to the optical communication field that optical communication technique field, particularly packing density are high, reliability requirement is high, specifically a kind of MPO socket that can dock with standard MPO plug.

Background technology

The MPO joints of optical fibre are a kind of multi-fiber connectors, are applicable to the high density occasion that installing space is little, light path quantity is many, and the previous MPO connector of order can transmit at most 72 tunnel optical-fibre channels simultaneously. Traditional MPO connector is by a MPO male, and a MPO female and a MPO adapter support the use. MPO adapter with flange arrangement is fixed on panel, and MPO male and female are inserted MPO adapter from the both sides of panel respectively, realize the connection of light path. Along with MPO connector is in the application of the military scenario such as carrier-borne, airborne, the version of this male-adapter-female can not meet the demands, for example in the narrow and small box-shaped device of inside dimension, need integrated output MPO interface, device interior does not have sufficient space that MPO male or female are installed, and MPO adapter is with flange mounting disc, take more erecting of panel area, be unfavorable for integrated, the miniaturization of equipment. On the other hand, traditional MPO adapter is generally linked together by ultrasonic bonding by two shapes, the identical a pair of plastic shell of size, after plug after a while, the gathering of related pressure or external force maybe can cause two plastic shells mutually to tear or come off coming, the reliability of this MPO adapter is not high, and these shortcomings have greatly limited the application of MPO connector.

Summary of the invention

In order to address the above problem, it is a kind of simple in structure that the utility model is to provide, and is easy to install the MPO fiber-optical socket that volume is little and reliability is high.

The present invention is achieved in the following manner.

A kind of MPO fiber-optical socket, mainly comprise MPO adapter head, socket upper shell, socket lower house and MT ferrule assembly, socket lower house one side is provided with the adaptive groove adapting with MPO adapter head, in adaptive groove, be provided with positioning boss, MPO adapter head withstands positioning boss and is placed in adaptive groove, socket lower house opposite side is provided with locating groove, socket upper shell is provided with upper shell boss, MT ferrule assembly is placed in upper shell boss and coordinates formed die cavity with locating groove, socket upper shell has counter sink, on socket lower house, be drilled with tapped through hole, when installation, screw pierces tapped through hole by counter sink, socket upper shell and socket lower house are connected as a single entity.

Wherein, locating groove is slightly larger than the size of MT ferrule assembly.

In addition, the tapped through hole of socket lower house setting can be used as installing hole, and this socket is installed from bottom surface.

Adaptive groove is rationally set the utility model and boss is installed location, makes MPO adapter head can accurately engage location, MT assembly can float design, reduced docking active force; Upper and lower casing is threaded, and installs, dismantles simply, is convenient to the clean maintenance of MT insertion core end face; Install bottom surface, saves interface board space. Compared with prior art volume is little, installing space is little, simple in structure, reliability is high, clean easy to maintenance.

Detailed description of the invention

Embodiments of the invention describe with reference to the accompanying drawings. Just each embodiment of the present invention for convenience of explanation of accompanying drawing, is not to carry out to the present invention the explanation of exhaustive, neither limit scope of the present invention. Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technical scheme of the present invention in detail.

As Fig. 1, shown in 2, the utility model comprises MPO adapter head 1, socket upper shell 2, socket lower house 3 and MT ferrule assembly 4, socket lower house 3 one sides are provided with the adaptive groove 8 adapting with MPO adapter head 1, in adaptive groove 8, be provided with positioning boss 9, MPO adapter head 1 withstands positioning boss 9 and is placed in adaptive groove 8, socket lower house 3 opposite sides are provided with locating groove 11, socket upper shell 2 is provided with upper shell boss 10, MT ferrule assembly 4 is placed in upper shell boss 10 and coordinates formed die cavity with locating groove 11, socket upper shell 2 has counter sink 12, on socket lower house 3, be drilled with tapped through hole 13, when installation, screw 5 pierces tapped through hole 13 by counter sink 12, socket upper shell 2 and socket lower house 3 are connected as a single entity.

One end of MPO adapter head 1 is provided with adaptive mouthful 7 of MPO, and the other end is provided with flange 6, and flange 6 is fastened in socket lower house 3 draw-in grooves 8, and MPO can dock with the MPO plug of standard for adaptive mouthful 7, realizes light path and connects.

On socket upper shell 2, be also provided with adaptive groove, when installation, the adapter head flange 6 of MPO adapter head 1 embeds wherein.

Locating groove 11 is slightly larger than the size of MT ferrule assembly 4, MT ferrule assembly 4 can be floated therein, the stress while reducing to install. The tapped through hole 13 that socket lower house 3 arranges can be used as installing hole, and this socket is installed from bottom surface, saves the installing space of docking panel.
