Description

The quick assembly mechanical connector of optical fiber

Technical field:

The utility model relates to optical communication field, particularly a kind of optical fiber field assembly mechanical connector.

Background technology:

Realize that having continued of optical fiber link flexibly connects and be fixedly connected dual mode; And the optical fiber fixed connection mainly contains Fusion Joining and mechanical splice dual mode; Flexibly connect and adopt flexible jumper to realize; Mechanical splice adopts optical fiber field assembly mechanical connector to realize, but existing fiber assembled on site mechanical connector has following main shortcomings:

1: existing optical fiber field assembly mechanical connector is because the matching fluid of filling up between fiber end face is in an open relatively environment; Loss and performance also can change easily along with the prolongation of tenure of use, and then directly influence the serviceable life of optical fiber field assembly mechanical connector.

2: existing optical fiber field assembly mechanical connector is because the matching fluid of filling up between fiber end face is in an open relatively environment; In the repetitive operation that carries out fibre junction; Matching fluid is come out by fibre ribbon easily and the amount of matching fluid is sharply reduced with the increase of multiplicity, and then directly influences the repeated use number of times of optical fiber field assembly mechanical connector.

The utility model content:

The purpose of the utility model provides a kind of optical fiber field assembly mechanical connector.In order to solve following technical matters:

1: the optical fiber matching fluid of this optical fiber field assembly mechanical connector is in the environment of a relative closure; Matching fluid can not be lost with the increase of tenure of use; And the performance that can effectively protect matching fluid can be not in time passing and change, and then can improve the tenure of use of optical fiber field assembly mechanical connector.

2: the optical fiber matching fluid of this optical fiber field assembly mechanical connector is in the environment of a relative closure; The optical fiber that when needs repeat to continue, is drawn out of can not taken matching fluid out of; It is stable that the amount of matching fluid can keep, and therefore can improve the multiplicity of optical fiber field assembly mechanical connector greatly.

The concrete technical scheme that addresses the above problem is following:

This optical fiber field assembly mechanical connector is made up of last V groove, following V groove, slide block, lock pin, overcoat, interior cover, straight cover, swivelling cover, covered wire cable folder, outer guide, dust cap; It is characterized in that; Described V groove down is provided with the enclosed matching fluid accumulator tank of rectangle; Pre-buried fibre and the fine fiber end face contact point of registering one's residence are just in time in the centre position of matching fluid accumulator tank; Last V groove utilizes slide block and following V groove tightly to stick together, and to guarantee the accurate collimation of the pre-buried fibre and the fine fibre core of registering one's residence, in rectangular matching fluid accumulator tank, is marked with optical fiber matching fluid; The effect of optical fiber matching fluid is to fill fiber cut end clearance that out-of-flatness forms, and then improves the optical property index of optical fiber field assembly mechanical connector.

In the such scheme, said upward V groove, following V groove, slide block, outer guide are metal material or plastic material.

Beneficial effect:

With original compared with techniques, prior art can obviously improve the serviceable life of optical fiber field assembly mechanical connector, repeat to continue number of times and optical property index, has improved the adaptability of product to environment, and then has improved the comprehensive benefit and the synthesized competitiveness of product.
