[0021] like Figure 1 As shown, this embodiment provides a Type-C connector with a stable structure, including a male plug 1 and a female socket 2, the male plug 1 includes a shell 11 and a contact portion 12, the contact portion 12 is used to dock with the female socket 2, and the connector also includes two locking components symmetrically arranged about the male plug 1.
[0022] like Figure 1 , Figure 2 As shown, each locking assembly includes a protrusion 31, a button 32 and an elastic steel sheet 33. A first window is provided on the side wall of the contact portion 12, the protrusion 31 is located in the first window and protrudes from the first window, a second window is provided on the side wall of the shell 11, the button 32 is located in the second window and protrudes from the second window, the elastic steel sheet 33 is located in the male plug 1, the protrusion 31 and the button 32 are connected by the elastic steel sheet 33, a bend 331 is provided on one end of the elastic steel sheet 33 facing the shell 11, the bend 331 is connected to the shell 11, a groove 111 is provided in the shell 11, and the bend 331 is located in the groove 111.
[0023] exist Figure 2From the perspective, when the button 32 is pressed downward, the elastic steel sheet 33 moves downward, the bend 331 undergoes elastic deformation, and the elastic steel sheet 33 moves downward with the protrusion 31; after the button 32 is released, the bend 331 and the elastic steel sheet 33 are reset, so that the protrusion 31 protrudes out of the first window again, and the button 32 protrudes out of the second window.
[0024] like Figure 1 , Figure 4 As shown, a position corresponding to the female socket 2 and the protrusion 31 is provided with a limiting hole, and when the male plug 1 is inserted into the female socket 2, the limiting hole is used to clamp the protrusion 31. In order to facilitate the insertion of the male plug 1 into the female socket 2, in this embodiment, the end of the protrusion 31 facing the female socket 2 is semi-elliptical, and the other end is cylindrical.
[0025] In order to make the female socket 2 compatible, the position and size of the limiting hole shall be based on not affecting the compatibility of the female socket 2, that is, the female socket 2 can also be connected to other plugs except the male plug 1 of this embodiment.
[0026] When the male plug 1 is inserted into the female socket 2, the male plug 1 can be directly inserted into the female socket 2 because the front end of the protrusion 31 is semi-elliptical; after the male plug 1 is inserted into the female socket 2, the protrusion 31 is first squeezed and shrinks into the first window, and then under the action of the elastic steel sheet 33, the protrusion 31 is just stuck in the limiting hole of the female socket 2 to ensure that the male plug 1 is firmly connected to the female socket 2; when the male plug 1 is pulled out, the male plug 1 cannot be pulled out directly because the rear end of the protrusion 31 is cylindrical, and the staff needs to press the button 32 to cause the protrusion 31 to shrink into the first window. After the protrusion 31 is free from the restriction of the limiting hole, the male plug 1 can be smoothly pulled out.
[0027] After releasing the button 32, in order to further reset the elastic steel sheet 33, the present embodiment further comprises an elastic member, which is arranged in the housing 11 and is used to make the protrusion 31 protrude quickly from the first window and the button 32 protrude from the second window.
[0028] Regarding the specific implementation of elastic parts, there are two situations:
[0029] First: Figure 3 As shown, the elastic member is set as a V-shaped spring piece 4, one branch of the V-shaped spring piece 4 is connected to the shell 11, and the end of the other branch is connected to the elastic steel sheet 33. The V-shaped spring piece 4 is located below the button 32, and the angle of the V-shaped spring piece 4 is 30°~45°.
[0030] Second: the elastic member is set as a spring, the spring is located below the button 32, and the two ends of the spring are respectively connected to the elastic steel sheet 33 and the housing 11.
[0031] Considering that the male plug 1 of the Type-C connector is very small, the locking assembly in this embodiment can be applied to the Type-C connector and can naturally be applied to other types of USB connectors.
[0032] The above embodiments are only used to illustrate the technical ideas and features of the utility model, and are not intended to be the only or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
