The utility model relates to connector technical field, concretely is a kind of anti-pulling connector, including socket, recess is set in the socket side, the recess inside swing installation has the lever, the utility model work process can be divided into
insertion, locking and unlocking three stages,
insertion stage: plug is inserted into alignment
insertion slot, tenon pushes out fixture to open outwards, lever is linked with fixture at this time, convex axle is located at the bottom of sliding groove, locking stage: when plug is completely inserted in place, lever is raised, convex axle is driven along sliding groove to slide downward by sliding groove, push-pull lever is followed to push fixture to rotate inwards, make that card slot and tenon are completely engaged, while spring is compressed to produce elastic
potential energy, maintain locking state, unlocking stage: press down lever, convex axle slides, push-pull lever drives fixture to open outwards, release the locking of tenon, at this time, plug can be smoothly pulled out, the whole process is realized by mechanical linkage, need not extra tool, it is easy to operate and high reliability.
