DETAILED DESCRIPTION
[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned figure descriptions and any variations thereof are intended to cover non-exclusive inclusions.
[0036] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0037] The following is combined with Figure 1-3 This application is described in further detail.
[0038] An embodiment of the present application discloses a wiring terminal.
[0039] Reference Figure 1 and Figure 2 The terminal includes a rotating structure of a button. Specifically, the rotating structure includes a button 1 and a housing 2. A rotating shaft 11 and a rotating ring 12 are protruded from one side of the button 1. The circumference of the rotating shaft 11 and the rotating ring 12 are both smaller than their own diameters. The rotating shaft 11 and the rotating ring 12 are coaxially arranged, that is, the axis of the rotating shaft 11 and the axis of the rotating ring 12 are in the same straight line, and the diameter of the rotating shaft 11 is smaller than the diameter of the rotating ring 12.
[0040] The inner side of the housing 2 is correspondingly protruded with a first limiting ring 21 and a second limiting ring 22. The circumferences of the first limiting ring 21 and the second limiting ring 22 are both smaller than their own diameters. The first limiting ring 21 and the second limiting ring 22 are coaxially arranged, that is, the axis of the first limiting ring 21 and the axis of the second limiting ring 22 are in the same straight line, and the diameter of the first limiting ring 21 is smaller than the diameter of the second limiting ring 22. A limiting hole 23 is formed at the center of the first limiting ring 21, and a limiting ring groove 24 is formed between the first limiting ring 21 and the second limiting ring 22.
[0041] Among them, the rotating shaft 11 is rotatably connected to the limiting hole 23, and the rotating ring 12 is rotatably connected to the limiting ring groove 24. It should be noted that in order to ensure the stability of rotation between the button 1 and the housing 2, there are rotating shafts 11 on both sides of the button 1, and correspondingly, the number of the first limiting ring 21 and the second limiting ring 22 is two.
[0042] In practical applications, the rotating shaft 11 is rotatably connected to the limiting hole 23, and the rotating ring 12 is rotatably connected to the limiting ring groove 24 to realize the rotational connection between the button 1 and the housing 2. This can improve the connection strength and stability of the button 1 being rotatably connected to the housing 2, reduce the force on the rotating shaft 11, and effectively reduce the occurrence of the rotating shaft 11 breaking. In addition, even if the rotating shaft 11 breaks, the rotating connection between the button 1 and the housing 2 can be ensured by the rotating ring 12 being rotatably connected to the limiting ring groove 24, thereby improving the service life of the terminal.
[0043] In some embodiments, both sides of the button 1 are recessed to form a rotating ring groove 13, and each second limiting ring 22 is rotatably connected to each rotating ring groove 13, so that the second limiting ring 22 is rotatably connected to the rotating ring groove 13, further improving the connection strength and stability of the button 1 rotatably connected to the housing 2, thereby further improving the service life of the terminal.
[0044] In some embodiments, the housing 2 is provided with a first abutting surface 25, and the button 1 is rotated upward so that the top of the button 1 abuts against the first abutting surface 25, so that the button 1 is in an open state and the button 1 is restricted from further rotation, thereby limiting the opening angle of the button 1 and preventing the rotating ring 12 from disengaging from the limiting ring groove 24 as much as possible, thereby ensuring the subsequent normal rotation of the button 1.
[0045] In some embodiments, the housing 2 is further provided with a second abutting surface 26, which is arranged opposite to the first abutting surface 25, and the button 1 is rotated downward so that the bottom of the button 1 abuts against the second abutting surface 26, so that the button 1 is in a closed state, and the button 1 is restricted from further rotation, thereby limiting the closing angle of the button 1, and preventing the rotating ring 12 from being separated from the limiting ring groove 24 as much as possible, thereby ensuring the subsequent normal rotation of the button 1. In addition, the button 1 is in a horizontal state to facilitate the next rotation of the button 1.
[0046] Reference Figure 3 In some embodiments, the housing 2 is further provided with a third abutting surface 27, and the third abutting surface 27 is arranged opposite to the second abutting surface 26. The button 1 is rotated downward so that the top of the button 1 abuts against the third abutting surface 27, and the third abutting surface 27 cooperates with the second abutting surface 26, so that the button 1 is more stably in the closed state, thereby improving the stability of limiting the closing angle of the button 1.
[0047] Reference Figure 1 and Figure 2In some embodiments, a rectangular snap-in block 28 is protruded from the inner side of the shell 2, and snap-in slots 14 are recessed on both sides of the button 1. The two snap-in slots 14 correspond to the two snap-in blocks 28. When the button 1 is turned downward so that the button 1 is in a closed state, the button 1 and the shell 2 have a certain elasticity, and the size of the snap-in slot 14 is larger than the size of the snap-in block 28, so that each snap-in block 28 is snapped into each snap-in slot 14. At this time, force is required to rotate the button 1 to ensure that the button 1 is stably in the closed state.
[0048] In some embodiments, a chamfer 29 is provided on the upper side of the snap-in block 28 away from the end of the housing 2. When the button 1 is rotated downward, the chamfer 29 abuts against the button 1 and guides the button 1, so that the snap-in block 28 is more easily snapped into the slot 14, thereby facilitating the closing of the button 1.
[0049] In some embodiments, the top and bottom of the button 1 are protruded with multiple anti-slip protrusions 15, and the anti-slip protrusions 15 are arranged in an arc-shaped block shape to facilitate the staff to hold, thereby facilitating the application of force to the button 1 and further facilitating the rotation of the button 1.
[0050] In some embodiments, both sides of the button 1 are provided with grooves 16 , and a worker can reach into the grooves 16 to rotate the button 1 , thereby further rotating the button 1 .
[0051] The implementation principle of this embodiment is as follows: in actual application, the rotating shaft 11 is rotatably connected to the limiting hole 23, and the rotating ring 12 is rotatably connected to the limiting ring groove 24 to realize the rotational connection between the button 1 and the housing 2, so that the connection strength and stability of the button 1 being rotatably connected to the housing 2 can be improved to reduce the force on the rotating shaft 11 and effectively reduce the occurrence of the breaking of the rotating shaft 11. Moreover, even if the rotating shaft 11 is broken, the rotational connection between the button 1 and the housing 2 can be ensured by the rotating ring 12 being rotatably connected to the limiting ring groove 24, thereby improving the service life of the terminal.
[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
