[0038] An embodiment of the present application provides a Type-c to Type-c adapter, referring to Figures 1-6 , comprising:
[0039] The inner shell 3 is provided with a terminal assembly 5, and the terminal assembly 5 is fixedly installed on the inner shell 3.
[0040] The outer shell 2 comprises two shell bodies 21, and the two shell bodies 21 jointly form a fully enclosed accommodating cavity, and the inner shell 3 is installed in the accommodating cavity.
[0041] The plastic sleeve 1 is sleeved on the outer shell 2 and is used for fixing and sealing the outer shell 2.
[0042] The embodiment solves the problem that the existing Type-c adapter and PCB welding points are prone to cracking or breaking, resulting in a decrease in the conductivity of the adapter. The terminal assembly 5 is directly connected and fixed in the inner shell 3, without the need for PCB conduction, avoiding the risk of cracking or breaking of the welding points between the terminal assembly 5 and the PCB during high-temperature injection molding, thereby improving the conductivity and long-term reliability of the adapter. The two housings 21 form a fully enclosed accommodation cavity, completely enclosing the inner shell 3 and the terminal assembly 5 in the housing 21, avoiding a decrease in the conductivity of the terminal assembly 5 due to high-temperature injection molding of the plastic sleeve 1, and enhancing the durability of the adapter. Specifically, the external connector extends into the outer shell 2 from the socket portion 31 and contacts the terminal 51 to achieve signal transmission. The terminal assembly 5 is fixedly connected with the inner shell 3 and is inserted into the two housings 21, and the two housings 21 form a fully enclosed accommodation cavity, completely enclosing the terminal assembly 5 and the inner shell 3 in the housing 21, which can fully protect the terminal assembly 5 and improve the reliability of the product, preventing the high-temperature injection molding of the plastic sleeve 1 on the outer shell 2 from affecting the conductivity of the terminal 51 due to excessive temperature.
[0043] Further, the terminal assembly 5 is provided in two rows, and the two rows of terminal assemblies 5 are centrally symmetrically arranged in the inner shell 3. By centrally symmetrically arranging the terminal assembly 5 in the inner shell 3, the inner shell 3 is more evenly stressed, the space in the inner shell 3 can be more efficiently utilized, the waste of inner shell 3 material is reduced, the stability of the structure is improved, and when subjected to external force, the symmetric structure can better disperse stress, reducing the risk of deformation and damage.
[0044] Further, the terminal assembly 5 includes a plurality of terminals 51, each of the plurality of terminals 51 includes two contact portions 512 and one fixed portion 511, the upper and lower surfaces of the inner shell 3 are formed with through grooves 32, the two contact portions 512 are located in the through grooves 32, and the fixed portion 511 is fixed in the through groove 32. In this embodiment, the terminal 51 is provided with two contact portions 512, and the terminal 51 is inserted into the through groove 32 through the fixed portion 511 to be fixed, so that the two contact portions 512 of the terminal 51 are located in the through groove 32. When the external connector is inserted into the outer shell 2 through the socket portion 31 and contacts the contact portion 512 of the terminal 51, current signal transmission can be achieved.
[0045] Further, the fixing portions 511 of the terminals 51 in the upper and lower rows are fixed in the through grooves 32 in a staggered manner. In this embodiment, the fixing portions 511 of the terminals 51 in the upper and lower rows are fixed in a staggered manner. By arranging the fixing portions 511 in a staggered manner, the fixing portions 511 are effectively prevented from being stacked at the same position, thereby reducing the height requirement of the inner shell 3, making the design of the entire electronic device more lightweight, improving the space utilization, making the layout in the inner shell 3 more compact, and enhancing the stability and firmness of the terminals 51. Even when the outer shell 2 is subjected to external force, the terminals 51 fixed in a staggered manner can better resist the risk of deformation and falling off.
[0046] Further, insulating members 4 are arranged between the upper and lower surfaces of the inner shell 3 and the shell 21. In this embodiment, the insulating members 4 are Mylar, which are arranged on the surfaces of the inner shell 3, matched with the shape of the inner shell 3, and completely cover the terminal assembly 5. The insulating property and temperature resistance of Mylar can further prevent the risk of degradation of the conductive property of the terminal assembly 5 due to high temperature generated by high-temperature injection molding of the plastic sleeve 1 on the outer shell 2.
[0047] Further, the inner shell 3 is further provided with clamping hooks 6. One side of the clamping hook 6 is provided with a plug-in portion 61 mounted on the inner shell 3, and the other side of the clamping hook 6 is provided with a barb 62. The side edges of the two shell 21 are provided with connecting grooves 21, and the barb 62 is connected with the connecting grooves 21. In this embodiment, the clamping hook 6 is connected with the connecting grooves 21 of the outer shell 2 through the barb 62, which can effectively prevent the shell 21 and the inner shell 3 from being loose, and ensure the stability of the structure.
[0048] Further, the width of the plastic sleeve 1 is greater than the distance between the connecting grooves 21 when the two shell 21 are connected. In this embodiment, when the two shell 21 are arranged on the inner shell 3 and fixedly connected with the inner shell 3, the plastic sleeve 1 is tightly attached to the surface of the shell 21 through high-temperature injection molding process. By arranging the plastic sleeve 1 at the connecting position of the two shell 21, the small gap at the connecting position of the two shell 21 can be sealed, the tightness and stability of the structure are enhanced, external pollutants are prevented from entering the shell 21, and the conductive property of the terminal assembly 5 is affected. Moreover, the width of the plastic sleeve 1 is greater than the distance between the two connecting grooves 21 when the two shell 21 are connected, that is, the plastic sleeve 1 can seal the connecting grooves 21 on both sides of the shell 21, so as to ensure that the connecting position of the shell 21 will not be damaged due to the erosion of the external environment.
[0049] Further, the inner shell 3 is provided with four elastic sheets 7, the four elastic sheets 7 are respectively fixed on the upper and lower surfaces of the front and rear ends of the inner shell 3, the four elastic sheets 7 are respectively provided with a plurality of bent buffer sheets 71, and the inner shell 3 is provided with buffer grooves 33 matched with the plurality of buffer sheets 71. In this embodiment, when the external connector is inserted into the inner shell 3, the buffer sheets 71 are extruded, the buffer sheets 71 are extended to the position of the buffer grooves 33, and the buffer sheets 71 on the upper and lower sides can clamp the external connector to fix the external connector, so that stable transmission is realized.
[0050] Further, the elastic sheet 7 is provided with a buckling portion 72 at both ends, the inner shell 3 is provided with buckling grooves 34 on both sides, and the buckling portion 72 is connected with the buckling groove 34 to fix the elastic sheet 7 to the inner shell 3. In this embodiment, when the elastic sheet 7 is placed on the inner shell 3, the elastic sheet 7 is pressed downward, the buckling portion 72 of the elastic sheet 7 is elastically deformed, that is, the buckling portion 72 is bent toward the position of the buckling groove 34, when the buckling portion 72 contacts the edge of the buckling groove 34, due to the elasticity of the buckling portion 72, the buckling portion 72 is buckled into the buckling groove 34 and connected with the inner shell 3, so that stable and reliable fixing effect is realized, when external impact or vibration is encountered, the elastic sheet 7 can always be fixed on the inner shell 3, and is not easy to fall off or loosen, so that the durability of the adapter is improved, and the external connector cannot be clamped due to the loosening of the elastic sheet 7, so that the connector is easy to fall off from the adapter, and contact failure is caused.
[0051] Further, the shell 21 is provided with a handle 22 for gripping. When the inner shell 3 needs to be installed in the shell 21, the inner shell 3 can be more conveniently inserted into the shell 21 by gripping the handle 22.
[0052] The above is only an optional embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structural transformation made by using the contents of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection range of the present application.
