Problems solved by technology

When the optical splitter is packaged, it will be fixed in the optical splitter packaging box. Generally, there will be holes on the side of the packaging box, but the existing technology will use drilling equipment to open the holes after the box body is formed, and the processing efficiency is low. , and the packaging box will be set in an outdoor environment and will suffer from a harsh environment. The existing packaging boxes are generally made of plastic, and a large part of it is polypropyl ether, which has outstanding electrical insulation and water resistance. The flame retardant performance is also relatively good, but the general polypropyl ether has poor stress tolerance and is easy to crack, and it is difficult to process due to its high viscosity during processing.

Abstract

The invention belongs to the field of communication equipment, and particularly relates to a packaging box. The packaging box comprises a box body, a plurality of open holes are formed in the side face of the box body, and the box body is formed in a one-off injection molding mode and is made from, by mass, 100-200 parts of poly(phenylene oxide), 30-50 parts of polyamide, 3-5 parts of dispersant, 2-4 parts of compatilizer and 1-3 parts of anti-aging agent. The product is formed in a one-off mode, so that working time is greatly shortened, and production efficiency is improved; besides, the product is easy to process, resistant to stress and not prone to cracking.

Description

technical field [0001] The invention belongs to the field of communication equipment, and in particular relates to a packaging box. Background technique [0002] An optical splitter, also known as an optical splitter, is one of the important passive components in an optical fiber link. It is an optical fiber junction device with multiple input ports and multiple output ports. When the optical splitter is packaged, it will be fixed in the optical splitter packaging box. Generally, there will be holes on the side of the packaging box, but the existing technology will use drilling equipment to open the holes after the box body is formed, and the processing efficiency is low. , and the packaging box will be set in an outdoor environment and will suffer from a harsh environment. The existing packaging boxes are generally made of plastic, and a large part of it is polypropyl ether, which has outstanding electrical insulation and water resistance. The flame retardant performance i...
