Abstract
The utility model discloses a fixing structure for a plug unit and a receptacle unit in a connector. The fixing structure is characterized in that a locking buckle is of a sheet structure and is integrated into an outer shell, one end of the locking buckle and a locating flange are snapped to each other and thus a barb part is formed at the end, the other end of the locking buckle is in hinged joint with the outer shell and thus a hinged joint part is formed at the end, and a sunken part allowing a part of the barb part to be embedded in is arranged at the joint between a locating part and the locating flange. Based on the technology of sealed snap joint between a box body and a box cover, which is usually applied to a special lunch box of a microwave oven, the sealed snap joint structure is applied for the connector. The fixing structure is highly reliable; one only needs to pull the sheet-like locking buckle lightly and enable the barb part to turn upwards, make plugging connection pins and cavities in plugging connection fit, and then push the sheet-like locking buckle lightly for enabling the barb part to be snapped to the locating flange; no great effort is needed, the phenomena that it is hard for the barb part to reset is avoided, and the firm and reliable connection between the plug unit and the receptacle unit can be guaranteed even after long-time use.
