Abstract
The invention relates to a hot-melt field-assembled optical fiber connector. The connector comprises a preset optical fiber, a ferrule, a spring, a front bracket, a connecting bracket, a heat-shrinkable protective casing, a rear seat, an optical fiber holder, an extension casing, a jacket and a reed. When the hot-melt optical fiber connector is assembled, completion of two-time welding in the same optical fiber connector can be achieved by controlling the length of the cut fiber and the position of the heat-shrinkable protective casing. The connector has the following advantages: the connector breaks through the defect that the traditional hot-melt field-assembled optical fiber connectors can be just welded once and can be reused, thus greatly increasing the assembly success rate, saving the field assembly time and effectively lowering the cost; and the welding method and structure are suitable for various types of hot-melt field-assembled optical fiber connectors such as SC and LC.
Description
Technical field
The present invention is a kind of heat molten type field assembled joints of optical fibre, belongs to heat molten type field assembled joints of optical fibre technical field.
