A strap connector includes an insulating body, a conductive element, a locking member, a pressing block, and a strap connected with the pressing block. The locking member includes a main body portion and a locking elastic arm. The main body portion includes a top plate. The locking elastic arm extends from the top plate and is used for locking with a mating connector. The pressing block is slidable backwardly under the pulling of the strap, so that the pressing block presses the top plate downwardly, and then the locking elastic arm moves downwardly to realize unlocking. When the unlocking method disclosed in the present disclosure is performed, it is only necessary to ensure that the pressing block slides over the top plate, which improves the reliability of unlocking.
