[0002] The tail accessory of the existing plug connector is generally a straight tail accessory, but in some specific occasions, if the connector cable needs to be turned when the connector tail cable is connected, the natural bending without fixation may cause electrical connection failure under vibration or impact. At this time, the connector with a bend tail accessory is needed to fix the cable. The bend tail accessory of the existing electrical connector is mostly achieved by end face ratchet engagement to prevent rotation, but the cable outlet angle is affected by the number of ratchets, and only a specific angle of the outlet position can be achieved, which cannot meet the installation requirements of any angle and any position, and cannot meet the requirements of small space or some specific occasions with size limitations. The common bend structure has complex processing technology, difficult processing, high manufacturing cost, large size and low connection density. SUMMARY
