Optical fiber element packaging box

Abstract

The invention relates to an optical fiber element packaging box. The optical fiber element packaging box comprises a plastic shell and a plastic cover, wherein the plastic shell and the plastic cover are connected in a sealing mode. A through hole is formed in one side face of the plastic shell, an optical platform and an optical metal pipe are arranged in the plastic shell, an optical element set and a collimator are fixed on the optical platform, the output end of the collimator is connected with one end of an optical fiber, the optical fiber is sealed on the optical metal pipe through soldering tin, and the optical metal pipe is sealed and fixed in the through hole of the plastic shell. A nut is arranged on the bottom of the plastic shell. The optical platform is provided with a through hole, a screw penetrates through the through hole to enable the optical platform to be locked and fastened to the nut, and the optical platform is fixed in the plastic shell. Through the adoption of the structure, the optical platform is fixed through the single screw, the contact surface of the optical platform with the external world can be reduced, and external disturbance caused by environment temperature changes or external stress changes can be effectively prevented from influencing optical elements on the optical platform.

Description

technical field [0001] The invention relates to a container for storing optical fiber communication components, in particular to a packaging box for optical fiber components. Background technique [0002] Commonly used optical passive or active device optical element shells are mostly made of stainless steel, and their cost is relatively high. In order to reduce costs, the metal holes on the side of the box are used to connect internal components and external optical signals, and the metal holes are sealed by welding or glue sealing. Optical components are precision parts, which are susceptible to disturbances caused by changes in ambient temperature and external stress during handling, transportation and use, which will cause damage to optical components. In the prior art, in order to save costs, plastic or foam molding is generally used to make a cavity that matches the optical element, and each optical element is prevented from being placed in the cavity. When the optica...

Problems solved by technology

In the prior art, in order to save costs, plastic or foam molding is generally used to make a cavity that matches the optical element, and each optical element is prevented from being placed in the cavity. When the optical element is placed in this packaging box, the gap between the optical element and the packaging There will be slight relative movement, resulting in slight damage to the surface of the optical element; at the same time, the optical element is in direct contact with the cavity, which is susceptible to changes in ambient temperature, resulting in changes in the characteristics of the optical element in the housing
