Optical fiber fixing device

An optical fiber fixing device for fixing a plurality of optical fibers, comprising:

• a substrate having a loading surface, wherein a plurality of poles are positioned on the loading surface and are evenly spaced apart from each other, each two adjacent poles cooperate to form a receiving groove therebetween, the receiving groove is configured for receiving two of the optical fibers;
• a cover rotatably connected to one end of the substrate;
• a locking assembly for locking the cover and the substrate;
• and
• a fixing plate extending from the cover and facing the substrate, wherein the fixing plate comprises a main body and a plurality of abutting portions each corresponding to a receiving groove, each of the abutting portions comprises two opposite abutting surfaces, the abutting surfaces are inclined with respect to the loading surface, each of the abutting surfaces faces a respective one of the poles, and thus the two abutting surfaces of each of the abutting portions cooperate with the respective poles and the loading surface to fix two of the optical fibers in the corresponding receiving groove;
• wherein an included angle formed between each abutting surface and the loading surface is about 45 degrees, each of the abutting portions comprises a connecting surface connected to its two abutting surfaces, the connecting surface is opposite to the loading surface, and an included angle formed between each abutting surface and the connecting surface is about 135 degrees.
