Description

Technical Field

[0001] This utility model relates to a plug connector, and more particularly to a plug connector that is easy to store and has good stability. Background Technology

[0002] With the development of electronic technology, plug connectors are widely used in various electronic devices. By plugging the plug connector of an electronic device into a wall socket or extension cord socket, power is supplied to the electronic device.

[0003] For ease of storage and portability, existing plug connectors have a foldable storage function. For example, Utility Model Patent Publication No. 219659059 discloses a press-lock assembly for a foldable plug mechanism, comprising a mounting base, two movable seats movably disposed on the mounting base, and at least one first return spring abutting against the movable seats. The mounting base has a folding groove to accommodate a plug assembly. A locking hook is formed on each of the two movable seats, and a pressing handle extending to the outside of the mounting base is connected to each movable seat. When the plug assembly is folded and accommodated in the folding groove, the elastic force of the first return spring causes relative displacement of the movable seats. At this time, the locking hooks engage the prongs of the plug assembly, thereby fixing the plug assembly in place. When it is necessary to unfold the plug assembly, pressing the pressing handle inward brings the two movable seats closer together and compresses the first return spring. At this time, the prongs of the plug assembly disengage from the locking hooks, thereby allowing the plug assembly to pop out of the folding groove. While this structural design can achieve convenient storage, the locking hook structure has low rigidity. Under improper force, the locking hook structure is prone to deformation or even breakage. Furthermore, the spring structure is prone to elastic fatigue after long-term repeated compression, which makes it impossible to effectively limit the position between the plug assembly and the mounting base, thereby affecting the durability of the plug connector.

[0004] Given the above shortcomings, it is necessary to provide a plug connector that is easy to store and has good stability. Summary of the Invention
