Description

Optical fiber connector

Technical Field

The utility model relates to an optical communication technical field is an optical fiber connector particularly.

Background

In a multi-channel optical system or optical circuit, there may be connections between fiber optic connectors, such that two MPO connectors are mated using fiber optic adapters. And the optical fiber connector and the optical fiber ferrule are jointed.

In addition, a simpler application scenario exists, in which two MT ferrules are connected, and the connection has a low requirement for repeated plugging and unplugging, but has a higher requirement for space and structural simplicity.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to solve above-mentioned problem, design a fiber connector, its characterized in that includes: the support tail pipe is sleeved at the rear section of the connector shell; a connector housing; the special-shaped spring is arranged in the connector shell, the MT insertion cores are arranged outside the special-shaped spring, the MT insertion cores are connected with the front section of the special-shaped spring, and the MT insertion cores are arranged inside the connector shell; the MT guide pin and the fixed seat are matched and coupled with the insertion core guide pin hole and fixed on the optical fiber.

Preferably, the connector housing adopts a single-part structure, and an external MT ferrule buckling position and an internal MT ferrule buckling position are arranged inside the connector housing.

Preferably, the special-shaped spring is divided into three sections, the inner diameter of the front section is larger than the inner diameters of the middle section and the rear section, the support is provided for the external MT insertion core, the shape and the inner diameter of the middle section are gradually changed, the optical fiber is avoided being bent, the inner diameter of the rear section is larger than 3mm, and the optical fiber penetrates through the special-shaped spring.

Compared with the prior art, the utility model, its advantage lies in:

1. compared with the traditional MPO connector and adapter assembly scheme, the scheme only uses one shell and tail tubes to connect two MT ferrules;

2. the occupied space is small, and the occupied volume of the scheme is only 50 percent of that of the traditional MPO connector;

3. the connection exposed length is short (27.8 mm), and compared with the traditional connection (48.1 mm), the tension arm is greatly reduced under the same tensile resistance, so that the bending strength of the connector is enhanced;

4. the single shell structure avoids the mechanical failure phenomenon caused by the assembly of a plurality of parts.
