The conductive terminal 1 includes a positive conductive terminal 11 and a negative conductive terminal 12, and the positive conductive terminal 11 and the negative conductive terminal 12 are centrally symmetrically arranged. The positive conductive terminal 11 and the negative conductive terminal 12 enable the circuit to form a complete loop. The front contact terminal 21 and the back contact terminal 22 are connected to each other, so that there is no need for a PCB board, and the connection between Type-C and USB can be achieved, realizing real-time data transmission, greatly simplifying the processing technology and cost.

In order to ensure the abutment between the front positive contact terminal elastic block 2111 and the back positive contact terminal elastic block 2211 and the abutment between the front negative contact terminal elastic block 2121 and the back negative contact terminal elastic block 2221, a first data rubber core 31 is cast on the outer sides of the front positive contact terminal top plate 2112, the back positive contact terminal top plate 2212, the front negative contact terminal top plate 2122 and the back negative contact terminal top plate 2222.

The first data rubber core 31 makes the connection between the front contact terminal 21 and the back contact terminal 22 fit more closely. The conductive terminal 1 includes a positive conductive terminal 11 and a negative conductive terminal 12 that are centrally symmetric to each other. The positive conductive terminal 11 and the negative conductive terminal 12 are respectively arranged on both sides of the first data rubber core 31. The positive conductive terminal 11, the first data rubber core 31, and the negative conductive terminal 12 are integrally coated by injection molding to form a first inner rubber holder 33, and the positive conductive terminal 11, the second data rubber core 41, and the negative conductive terminal 12 are integrally coated by injection molding to form a second inner rubber holder 43, so as to fully combine the conductive terminal 1 and the data terminal 2, enabling direct data transmission between the front contact terminal 21 and the back contact terminal 22 at the Type-C end and the USB end after conduction, and enabling external devices to be inserted on both the front and back of the Type-C end and the USB end.

[0064] An embodiment of the present application also discloses a manufacturing method of an adapter. Refer to Figures 8 - 13 , the manufacturing method of the adapter includes the following steps:

[0065] Step S1, injection-mold the first data rubber core 31 and the second data rubber core 41. The first data rubber core 31 and the second data rubber core 41 coat the front contact terminal 21 and the back contact terminal 22 into one body to form the data terminal 2. First partition pieces 311 extend outward from both sides of the first data rubber core 31, and second partition pieces 411 extend outward from both sides of the second data rubber core 41.

[0066] Refer to Figure 8 and Figure 9, specifically, a stamping machine is used to cut and stamp to form continuous contact terminals connected by a metal strip. The metal strip is cut so that the continuous contact terminals become individual contact terminals with part of the metal strip at both ends. The two contact terminals are placed in the first mold in a central symmetry (one positive and one negative) as the front contact terminal 21 and the back contact terminal 22 respectively. When the front contact terminal 21 and the back contact terminal 22 are placed in the first mold, the front positive contact terminal elastic block 2111 and the back positive contact terminal elastic block 2211 remain in contact, and the front negative contact terminal elastic block 2121 and the back negative contact terminal elastic block 2221 remain in contact. Liquid plastic is injected into the first mold. After the plastic cools and demolds, the first data rubber core 31 and the second data rubber core 41 that wrap the front contact terminal 21 and the back contact terminal 22 can be obtained. The front contact terminal 21 and the back contact terminal 22 are kept connected through the first data rubber core 31 and the second data rubber core 41. The two sides of the first data rubber core 31 extend outward to form the first separator 311, and the two sides of the second data rubber core 41 extend outward to form the second separator 411. By removing the strips of the front contact terminal 21 and the back contact terminal 22, the data terminal 2 can be obtained.

[0067] Step S2, injection molding to form the first inner rubber frame 33 and the second inner rubber frame 43. The first inner rubber frame 33 wraps the first data rubber core 31, the positive conductive terminal 11, and the negative conductive terminal 12 that cover the front contact terminal 21 and the back contact terminal 22 into one body. The second inner rubber frame 43 wraps the second data rubber core 41, the positive conductive terminal 11, and the negative conductive terminal 12 that cover the front contact terminal 21 and the back contact terminal 22 into one body. Part of the positive conductive terminal 11 and part of the negative conductive terminal 12 are respectively arranged on the upper and lower sides of the first separator 311. Part of the positive conductive terminal 11 and part of the negative conductive terminal 12 are respectively arranged on the upper and lower sides of the second separator 411.

[0068] Refer to Figure 10, specifically, a stamping machine is used to cut and stamp to form uninterrupted conductive terminals connected by a metal strip. The metal strip is cut so that the uninterrupted conductive terminals become single conductive terminals with partial metal strips at both ends. One conductive terminal is placed in the second mold, and the obtained data terminal 2 is placed into the second mold. Then, another conductive terminal that is centrosymmetric (i.e., placed in the reverse direction) to the previously placed conductive terminal is placed into the second mold to form a positive conductive terminal 11 and a negative conductive terminal 12. The positive conductive terminal 11 and the negative conductive terminal 12 are separated by a first separator 311 on the first data rubber core 31 and a second separator 411 on the second data rubber core 41. When the positive conductive terminal 11 and the negative conductive terminal 12 are placed in the second mold, the overlapping end faces of the first positive conductive terminal elastic plate 1111 and the second positive conductive terminal elastic plate 1121 keep abutting against each other, and the overlapping end faces of the second negative conductive terminal elastic plate 1221 and the first negative conductive terminal elastic plate 1211 keep abutting against each other. Liquid plastic is injected into the second mold. After the plastic cools and demolds, a first inner rubber sleeve 33 that wraps the first data rubber core 31, the positive conductive terminal 11, and the negative conductive terminal 12 and a second inner rubber sleeve 43 that wraps the second data rubber core 41, the positive conductive terminal 11, and the negative conductive terminal 12 can be obtained. The positive conductive terminal 11 and the negative conductive terminal 12 are kept connected through the first inner rubber sleeve 33 and the second inner rubber sleeve 43. After demolding and taking out, the metal strips of the positive conductive terminal 11 and the negative conductive terminal 12 are removed.

[0069] Step S3: Prepare a metal shell 44, and the metal shell 44 is inserted into the second inner rubber sleeve 43.

[0070] Refer to Figure 11 , specifically, in this application, the metal shell 44 is the metal part of the Type-C socket. The metal shell 44 is inserted into the second inner rubber sleeve 43 to protect the second inner rubber sleeve 43.

[0071] Step S4: Prepare a second housing 42, and the mutually inserted second inner rubber sleeve 43 and the metal shell 44 are assembled into the second housing 42.

[0072] Refer to Figure 12 , specifically, in this application, the second housing 42 is made of plastic material. The metal shell 44 with strong thermal conductivity and electrical conductivity is assembled inside the second housing 42 to protect it and ensure the safety when used by humans.

[0073] Step S5: Prepare a first housing 32, assemble the first data rubber core 31 into the first housing 32, and the end of the second housing 42 facing the first housing 32 is inserted into the first housing 32.

[0074] Refer to Figure 13, specifically, the first housing 32 in the present application is made of a metal material with low thermal conductivity and electrical insulation, and the first housing 32 is the metal part of the USB socket, with a first data rubber core 31 assembled inside to protect the first data rubber core 31.

[0075] The implementation principle of the manufacturing method of the adapter according to the embodiment of the present application is as follows: two centrosymmetric contact terminals are formed by stamping to form a front contact terminal 21 and a reverse contact terminal 22. The end faces of the front contact terminal 21 and the reverse contact terminal 22 are abutted together by an injection molding process to form a first data rubber core 31 and a second data rubber core 41. Then, two centrosymmetric conductive terminals are formed by stamping to form a positive conductive terminal 11 and a negative conductive terminal 12. The positive conductive terminal 11, the negative conductive terminal 12 and the first data rubber core 31 are combined and injection molded to form a first inner rubber frame 33. The positive conductive terminal 11, the negative conductive terminal 12 and the second data rubber core 41 are combined and injection molded to form a second inner rubber frame 43. After the second inner rubber frame 43 is inserted into the metal shell 44, the second housing 42 and the first housing 32 are installed to form a complete adapter housing.

[0076] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
