The invention discloses a processing technology for preparing a connector cover from polyether-ether-ketone, and belongs to the technical field of injection molding processing. The processing technology comprises the following steps: step 1, material selection: selecting polyether-ether-ketone as a raw material, and removing impurities in the raw material; 2, softening: adding the raw materials subjected to impurity removal into an injection molding machine, and heating and softening; the softened raw materials are injected into a mold through a first sprue, 80% of the materials are fed during first-section injection, the injection rate is 60-70 mm/s during injection, and the temperature is 360-380 DEG C; step 4, second-stage injection: after the first-stage injection is completed, a sprue II is opened, the remaining part is injected through the sprue II, and during the second-stage injection, the injection rate is 60-70mm/s, and the temperature is 370-390 DEG C; (5) mold opening: after second-section injecti
