Optical fiber coupling connector

An optical fiber coupling connector comprising:

• an optical coupling lens comprising a first body, two plugs, and two sliders, the first body comprising a first top surface and a first mounting surface perpendicularly connected to the first top surface, the first mounting surface defining two buffer gaps, the plugs protruding from the first mounting surface and located between the two buffer gaps, the sliders corresponding to the buffer gaps, each slider being located at one side of the corresponding buffer gap away from the first body, each slider defining an engagement groove facing away from the corresponding buffer gap;
• and
• a jumper connectable to the optical coupling lens, comprising a second body and two clamping arms, the second body comprising a second mounting surface entirely facing the first mounting surface, the second mounting surface defining two plug holes configured to receive the two plugs respectively, the clamping arms located at opposite sides of the second mounting surface and connected to the second mounting surface directly, the clamping arms protruding from the second mounting surface toward the first mounting surface, each clamping arm defining a slide groove corresponding to a slider, an engagement portion protruding from an inner surface of each slide groove toward the other slide groove, and each engagement portion engaging in an engagement groove connecting the jumper to the optical coupling lens.
