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 achieves convenient storage, the locking hook structure has low rigidity. Under improper force, the locking hook structure is prone to deformation or even breakage, which prevents the plug assembly from being effectively positioned with respect to the mounting base, thus 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

[0031] To illustrate the technical content, structural features, objectives, and technical effects of this utility model in detail, the following embodiments are provided in conjunction with the accompanying drawings.
[0032] Please see Figure 1 and Figure 3 This utility model discloses a plug connector 100, comprising a rectangular box-shaped outer shell 10, the outer shell 10 having a housing 1 and a cover 2 that engages with the housing 1, the housing 1 and the cover 2 together defining an internal space 23, a rotating seat 4 housed in the internal space 23 and pivotally connected to the cover 2, and at least one conductive spring 71 housed within the outer shell 10 and in contact with the rotating seat 4.
[0033] Please see Figure 3 , Figure 4 , Figure 6 , Figure 7 as well as Figure 9The rotating base 4 has a pivot shaft 44 and a plug assembly 43. The pivot shaft 44 is pivotally connected to the internal space 23, allowing the plug assembly 43 to switch between a state where it is contained within the internal space 23 and a state where it is exposed within the internal space 23. The rotating base 4 also includes a plug housing 41 with a rectangular shell, a mounting groove 411 formed by an inward recess from the rear surface of the plug housing 41, a fixing shaft 322 disposed in the mounting groove 411, the fixing shaft 322 being located at one end near the opening of the mounting groove 411, a connecting shaft 51 disposed in the mounting groove 411, the connecting shaft 51 being located at one end near the bottom of the mounting groove 411, and at least one elastic member 6 disposed in the mounting groove 411, the two ends of the elastic member 6 being pivotally connected to the fixing shaft 322 and the connecting shaft 51, respectively. The pivot shaft 44 extends to the left and right sides of the plug housing 41, and the extending direction of the pivot shaft 44 is orthogonal to the extending direction of the central axis of the rotating base 4. The axes of the pivot shaft 44, the fixed shaft 322, and the connecting shaft 51 are parallel to each other, the pivot shaft 44 and the connecting shaft 51 are aligned on the central axis of the rotating base 4, and the fixed shaft 322 is located on a side offset from the central axis of the rotating base 4.
[0034] Please see Figure 3 and Figure 6 In this embodiment, the elastic element 6 is configured as a tension spring. The rotating seat 4 is pivotally connected to the internal space 23 with the pivot shaft 44 as the rotation center. The tension and rebound force of the elastic element 6 position the rotating seat 4 in the use state and the storage state. When the rotating seat 4 rotates from the use state to the storage state or vice versa, the movable end of the elastic element 6 is stretched and stores elastic potential energy as the rotating seat 4 rotates. The tensile deformation of the elastic element 6 reaches its maximum value when the rotating seat 4 rotates to 45 degrees. After the movable end of the elastic element 6 rebounds and resets towards the fixed shaft 322, the rotating seat 4 is positioned in the use state or the storage state, thereby improving the insertion stability and storage stability of the plug connector 100.
[0035] Please see Figures 4 to 6 as well as Figure 9Furthermore, the opposite side walls of the mounting groove 411 have a first inner wall 411a and a second inner wall 411b, the first inner wall 411a and the second inner wall 411b being parallel to each other and perpendicular to the bottom of the mounting groove 411. When the rotating seat 4 is positioned in the fully extended position, the fixing shaft 322 is located on a side offset from the central axis of the rotating seat 4 and close to the first inner wall 411a. When the rotating seat 4 is positioned in the fully retracted position, the fixing shaft 322 is located on a side offset from the central axis of the rotating seat 4 and close to the second inner wall 411b.
[0036] Please see Figure 3 , Figure 8 as well as Figure 9 As shown in this preferred embodiment, to facilitate fixing the elastic element 6, the rotating base 4 is further provided with a detachable support 5 to facilitate fixing the elastic element 6 to the rotating base 4. The support 5 is received in the mounting groove 411, and the left and right sides of the support 5 extend outward to form the connecting shaft 51. The elastic element 6 is symmetrically assembled on the left and right sides of the fixed shaft 322 and the left and right sides of the connecting shaft 51. Each elastic element 6 has a first hook 61 and a second hook 62 at its front and rear ends, respectively. The first hook 61 is sleeved on the fixed shaft 322 and serves as the fixed end of the elastic element 6. The second hook 62 is sleeved on the connecting shaft 51 and serves as the movable end of the elastic element 6. When the rotating base 4 is rotated around the pivot shaft 44 and positioned on the cover 2, the movable end of the elastic element 6 is stretched away from the fixed shaft 322. Furthermore, to prevent the first hook 61 from disengaging from the fixed shaft 322, a stop 323 is formed at each of the left and right ends of the fixed shaft 322, and the outer diameter of the stop 323 is larger than the outer diameter of the fixed shaft 322. Similarly, to prevent the second hook 62 from disengaging from the connecting shaft 51, a stop portion 511 is formed at each of the left and right ends of the connecting shaft 51, and the outer diameter of the stop portion 511 is larger than the outer diameter of the connecting shaft 51.
[0037] Please see Figure 8 and Figure 9To ensure the support member 5 is securely housed in the mounting groove 411, the two opposite inner sidewalls of the mounting groove 41 are recessed to form a pair of locking grooves 412. These locking grooves 412 extend outwards from the bottom of the mounting groove 411 towards its opening, and the bottom of the mounting groove 411 is recessed forward to form a limiting groove 413. The support member 5 includes a body portion 52, a pair of supporting arms 53 extending rearwards and outwards from both ends of the body portion 52, and a limiting block 54 protruding forward from the front surface of the body portion 52. The body portion 52 is disposed at the bottom of the mounting groove 411, the supporting arms 53 are engaged in the locking grooves 412, and the limiting block 54 is engaged in the limiting groove 413, thereby achieving positioning and fixation between the support member 5 and the rotating seat 4. In this embodiment, the connecting shaft 51 protrudes outwards from the left and right sidewalls of the body portion 52.
[0038] Please see Figure 3 , Figure 8 as well as Figure 9 The internal space 23 houses a substrate 31. The front surface of the substrate 31 extends forward to form an extension 32. The fixing shaft 322 extends symmetrically outward from the left and right sides of the extension 32. The extension 32 and the fixing shaft 322 extend into the mounting groove 411. The inner and outer surfaces of the extension 32 each form a downwardly inclined and parallel guide surface 321. The opening of the mounting groove 411 is recessed inward to form two notches 414. The two notches 414 are located at the upper and lower ends of the mounting groove 411, respectively. The inner surface of each notch 414 forms an inwardly inclined engaging surface 415. The engaging surfaces 415 of the two notches 414 face each other symmetrically. The extension 32 engages in one of the notches 414. The engaging surface 415 is arranged to align with the guide surface 321, thereby limiting the extension 32 and the plug housing 41 to each other. When the rotating base 4 is in use, the front end of the plug assembly 43 extends out of the internal space 23, and the rear end of the plug assembly 43 is electrically in contact with the conductive spring 71. The guide surface 321 on the outer surface of the extension 32 is aligned with one of the engaging surfaces 415. When the rotating base 4 is in the retracted state, the plug assembly 43 and the conductive spring 71 are not in contact with each other. The rotating base 4 rotates 90 degrees about the pivot shaft 44 and is housed in the internal space 23. At this time, the guide surface 321 on the inner surface of the extension 32 is aligned with the other engaging surface 415.
