Optical coupling lens module and optical fiber connector

An optical fiber connector, comprising:

• a metal housing;
• two optical coupling components, disposed in the metal housing, each of the optical coupling components comprising:
• an optical coupling lens module, comprising:
• a body, having an inner bottom surface, a positioning protrusion, and a docking surface, wherein the positioning protrusion protrudes from the docking surface, the docking surface comprising a first abutting surface and a second abutting surface different from each other, the positioning protrusion occupying a portion of the first abutting surface and occupying a portion of the second abutting surface;
• a first convex lens, disposed on the inner bottom surface;
• a light reflecting element, disposed in the body;
• a second convex lens, disposed on the docking surface;
• a light source;
• a fiber jumper;
• and
• a circuit board component, the light source, the fiber jumper, and the body being respectively disposed on the circuit board component,
• wherein the two optical coupling lens modules of the two optical coupling components adjoin each other and are away from the metal housing, the two circuit board components of the two optical coupling components are opposite to each other with the two optical coupling lens modules therebetween to be adjacent to the metal housing, wherein the light source generates a light beam sequentially transmitted through the first convex lens, the light reflecting element, and the second convex lens to the fiber jumper.
