[0056] The utility model has various applications, including Figure 2 As shown, it includes a Type-C female socket used for a transfer circuit board. This transfer circuit board is mainly used to realize signal conversion between USB-A and Type-C.

[0057] like Figure 3 As shown, the utility model serves as a USB type c female socket data transmission structure of a Type-C female socket, which is composed of a metal conductor U1 and a tongue plate S2. The tongue plate S2 has a signal contact surface S2-a for signal transmission and power supply processing.

[0058] It is not difficult to see that the use of metal conductor U1 can significantly improve the service life of the USB type c female data transmission structure. The metal conductor U1 is wear-resistant. When replacing the negative pole of the USB type c female data transmission structure, it can also be used as an important means to improve mechanical properties. After more times of plugging and unplugging tests, the connection between the male head and the female head is still stable.

[0059] A card slot 1 is provided on the side of the metal conductor U1, and the card slot 1 is engaged with the card connector on the male connector to ensure the reliability of data transmission between the two.

[0060] In the first embodiment, from Figure 3 It can be seen that the metal conductors U1 distributed on both sides of the tongue plate S2 are connected by the top and bottom surfaces adjacent to each other through the connecting piece 2a, and the socket structure they constitute is assembled on the tongue plate S2 in the form of a socket, and a first snap-fit ​​structure is provided between the metal conductor U1 and the tongue plate S2 to connect them; the above scheme can ensure the reliability and stability of the connection between the two.

[0061] In addition, in the first embodiment, the tongue plate S2 is assembled into the socket structure in an inserted manner. Therefore, the outer end of the metal conductor U1 is set to the shape of a hook g, which cooperates with the inclined surface x at the outer end of the tongue plate S2. The two hooks g form a clamping claw. The two hooks g constrain the tongue plate S2 in the form of a clamp, and play the role of hanging the tongue plate S2 and limiting the tongue plate S2.

[0062] The first buckle structure is a first buckle opening k1 and a first buckle f1 that are engaged with each other. In the first embodiment, the first buckle opening k1 is located on the side of the metal conductor U1, and the first buckle f1 is a protruding portion formed on the side of the tongue plate S2.

[0063] The connector 2a may be a separate structure connected to the metal conductor U1, or may be integrated with the metal conductor U1.

[0064] like Figure 5-6 As shown, the insulator 3 is simultaneously sleeved on the above-mentioned connector 2a and the metal conductor U1, and the insulator 3 is snap-connected with the USB type c case 4a, thereby forming a complete USB type c shell.

[0065] Among them, a second buckle structure is provided between the USB type c case 4a and the insulator 3, a second buckle 31 is provided on the insulator 3, and a second bayonet 41 is provided on the USB type c case 4a, and the second buckle 31 is snapped into the second bayonet 41.

[0066] A contact area S2-b that is in contact and conductive with the metal conductor U1 is also formed at the root of the tongue plate S2. The connector 2a rests against the contact area S2-b. The metal conductor U1 can be conductively connected to the tongue plate S2 through the connector 2a and the signal contact surface S2-a, thereby expanding the conductive area and method between the metal conductor U1 and the tongue plate S2.

[0067] like Figure 7-8 As shown, in the second embodiment, a USB type c shell 4b is also included which is integrally formed with the metal conductor U3. The metal conductor U3 is located on the inner circumferential surface of the USB type c shell 4b. The position of the metal conductor U3 is fixed by the USB type c shell 4b to ensure the stability of the contact between the metal conductor U3 and the tongue plate S4.

[0068] like Figure 9-12 As shown, in the third embodiment, the metal conductor U2 is a frame, which is formed by stacking an upper hook R1 and a lower hook R2, and the roots of the upper hook R1 and the lower hook R2 are bent toward the upper and lower sides of the raised portion f2, so that an open structure for the tongue plate S3 to pass through is formed between the roots of the upper hook R1 and the lower hook R2. When the tongue plate U3 is located in the open structure, the root can cover the upper and lower sides of the raised portion f2, thereby forming an installation method that is sleeved on the tongue plate S3.

[0069] The upper hook R1 and the lower hook R2 are wrapped by a fixing member 5 formed of thermoplastic plastic so that they are in close contact with each other. In addition, the fixing member 5 has a first snap-in opening k2 on the area corresponding to the raised portion f2, which is snap-fitted and fixed with the raised portion f2.

[0070] The main advantage of this structure is that it uses a thermoplastic plastic molded fixing part 5. The first bayonet k2 does not need to be prepared by stamping. The punch of the stamping mechanism is prone to wear, and the stamped first bayonet k2 is prone to enlargement or deformation, and thus cannot be assembled with the raised part f2.

[0071] In addition, the frame can surround the side of the tongue plate S3, and this enclosure can make the frame U2 and the tongue plate S3 tightly spliced ​​together; in addition, the metal conductor U2 is fixed to the tongue plate S3 using the fixing piece 5, which has the advantage of low cost.

[0072] It should be noted that the protrusion U2-a formed on the frame is the negative power pole for grounding. An opening is reserved on the area of ​​the fixing member 5 corresponding to the protrusion U2-a for the protrusion U2-a to pass through and contact and conduct with the grounded negative power pole on the USB type c male connector.

[0073] like Figure 13-14 As shown, it is the fourth embodiment of the utility model. In this embodiment, after the metal conductor U4 is connected by the connector 2b, the connector 2b is attached to the tongue plate S5. Specifically, the metal conductor U4 and the tongue plate S5 are installed by using the existing patch parts. The patch machine absorbs the metal conductor U4 and vertically puts it on the tongue plate S5 from top to bottom. In other embodiments, the tongue plates S1, S2, S3, and S4 are inserted into the socket structure, or are sleeved by the socket structure. This embodiment has the characteristic of more convenient installation.

[0074] The structure of inserting the plug f3 into the socket k3 eliminates the influence of the mismatch between the position of the metal conductor U4 and the tongue plate S5 as much as possible. After installation, it is welded to the tongue plate S5 for conduction.

[0075] In yet another embodiment, the metal conductor U4 is welded to the tongue plate S5.

[0076] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
