[0002] The USB bus, as a high-speed serial bus, offers extremely high transmission speeds that meet the requirements of high-speed data transmission applications, making it widely used. Currently, the most common versions are USB 2.0 and USB 3.0. Compared to USB 2.0, USB 3.0 provides a higher ultra-high-speed transmission rate of 5.0 Gbit / s and is backward compatible with the transmission rate of USB 2.0. The USB 3.0 interface design differs; it uses a 9-pin design, while USB 2.0 uses a 4-pin design, meaning USB 3.0 has 5 more pins than USB 2.0.

[0003] The existing USB 3.0 pin design divides the 9-pin pins into two parts, and the pins of these two parts are assembled together to form a complete structure. However, this can easily lead to poor coplanarity between the terminal solder pads and the board end, resulting in large assembly tolerances. It can also easily cause insufficient solder paste leading to poor soldering, or excessive solder paste leading to short circuits in the connector. Furthermore, the stability of the terminal solder pads and contacts cannot be guaranteed, thus affecting the performance of the connector. Utility Model Content

Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] Please refer to Figures 1-10 This utility model proposes an integrated USB connector, including a housing 110, a main body 120 and a plurality of metal terminals 130, with the terminals disposed inside the main body 120; the main body 120 includes an upper part 121 and a lower part 122, which are arranged in a stepped manner; the housing 110 is disposed on the outer side of the main body 120; one end of the housing 110 extends along the upper surface of the upper part 121 to the first surface 1222 of the lower part 122, and forms a connection chamber 140 with the lower part 122, and the other end of the housing 110 corresponds to the shape of the main body 120.

[0038] In this embodiment, the metal terminal 130 includes an upper metal terminal 133 and a lower metal terminal 134. The upper metal terminal 133 and the lower metal terminal 134 are linearly arranged and stacked within the main body 120. The upper metal terminal 133 and the lower metal terminal 134 are also respectively provided with a first contact end 131 and a second contact end 132. The main body 120 includes an upper portion 121 and a lower portion 122. The upper portion 121 and the lower portion 122 are distributed in a stepped manner, and the overlap of the upper portion 121 and the lower portion 122 corresponds to the bend between the first contact end 131 and the second contact end 132 of the metal terminal 130. When the coplanarity of the first contact end 131 with the preset board end is not good, insufficient solder paste may lead to poor soldering, or excessive solder paste may lead to short circuit. The first contact end 131 of the upper metal terminal 133 and the first contact end 131 of the lower metal terminal 134 are fixed by the upper part 121 of the main body 120, so that the first contact end 131 of the upper metal terminal 133 and the first contact end 131 of the lower metal terminal 134 located outside the main body 120 are in the same plane, thereby improving the coplanarity problem of the first contact end 131 of the upper metal terminal 133 and the first contact end 131 of the lower metal terminal 134.

[0039] The main body 120 includes an upper part 121 and a lower part 122, and its shape corresponds to the body of the metal terminal 130. The upper metal terminal 133 and the lower metal terminal 134 are fixed inside the main body 120, and the outer side of the main body 120 is wrapped with a shell 110. One end of the shell 110 extends along the upper surface of the upper part 121 to the first surface 1222 of the lower part 122, and forms a connection chamber 140 with the lower part 122. The second contact end 132 of the upper metal terminal 133 and the second contact end 132 of the lower metal terminal 134 are disposed in the connection chamber 140. The shell 110 is integrally formed, and the shell 110 is also formed with an extension 111 and a first buckle 112, which are connected and fixed to a preset plate end through the extension 111 and the first buckle 112. The upper metal terminal 133 and the lower metal terminal 134 are respectively disposed in the connection chamber 140, and the second contact end 132 of the upper metal terminal 133 protrudes from the first surface 1222 of the lower part 122. The second contact end 132 of the lower metal terminal 134 is disposed on the lower part 122. The upper metal terminal 133 and the lower metal terminal 134 are integrally formed. The metal terminal 130 is disposed in the integrally formed body 120, which makes the connection between the first contact end 131 and the second contact end 132 more stable and reliable, and ensures the stability of the connector contact.

[0040] Please refer to Figures 7-9 The metal terminal 130 includes an upper metal terminal 133 and a lower metal terminal 134, which are arranged linearly and stacked.

[0041] In specific implementation: the first contact end 131 of the upper metal terminal 133 and the first contact end 131 of the lower metal terminal 134 are arranged crosswise on the same horizontal plane. The upper metal terminal 133 and the lower metal terminal 134 are bent for the first time, so that the upper metal terminal 133 and the lower metal terminal 134 are in different planes, thereby forming upper and lower planes. The upper metal terminal 133 is located in the upper plane and the lower metal terminal 134 is located in the lower plane, so that the upper metal terminal 133 and the lower metal terminal 134 form a linear arrangement and stacked structure, and are fixed by the main body 120, thereby making the metal terminal 130 occupy less space in the connector.

[0042] Please refer to the attached document. Figure 7 The upper metal terminal 133 and the lower metal terminal 134 are spaced apart and fixed by the main body 120.

[0043] In specific implementation: the upper metal terminals 133 are arranged linearly, and the lower metal terminals 134 are inserted sequentially between the two metal terminals 130 of the upper metal terminals 133, so that the upper metal terminals 133 and the lower metal terminals 134 are spaced apart, which allows the upper metal terminals 133 and the lower metal terminals 134 to be arranged in a limited space.

[0044] Please refer to the attached document. Figures 7-9 The upper metal terminal 133 and the lower metal terminal 134 are respectively provided with a first contact end 131 and a second contact end 132, and the first contact end 131 of the upper metal terminal 133 and the first contact end 131 of the lower metal terminal 134 are arranged in the same plane.

[0045] In specific implementation: the first contact end 131 of the upper metal terminal 133 and the first contact end 131 of the lower metal terminal 134 are located on the outside of the main body 120, and the portion between the first contact end 131 and the second contact end 132 of the metal terminal 130 is fixed by the main body 120. The metal terminal 130 between the first contact end 131 and the second contact end 132 is bent a second time, and fixed by the overlapping area of ​​the upper part 121 and the lower part 122. The height of the overlapping area of ​​the upper part 121 and the lower part 122 is greater than the height of the second bend of the metal terminal 130. The upper part 121 and the lower part 122 on the main body 120 can completely cover and fix the metal terminal 130, and the upper part 121 and the lower part 122 are integrally formed, so that the first contact end 131 of the upper metal terminal 133 and the first contact end 131 of the lower metal terminal 134 can be in the same plane, preventing poor coplanarity of the first contact ends 131 of the upper metal terminal 133 and the lower metal terminal 134 from affecting the performance of the connector.

[0046] Please refer to the attached document. Figure 2 -and Figure 10The second contact end 132 of the upper metal terminal 133 and the second contact end 132 of the lower metal terminal 134 are located in the connection chamber 140.

[0047] In specific implementation: the upper metal terminal 133 and the lower metal terminal 134 are both integrally formed and are respectively disposed in the connection chamber 140. The second contact end 132 of the upper metal terminal 133 protrudes from the first surface 1222 of the lower part 122, and the protrusion height of the second contact end 132 of the upper metal terminal 133 is less than the height of the upper part 121 of the main body 120. By fixing the metal terminal 130 with the integrally formed main body 120, the second contact end 132 of the upper metal terminal 133 located in the connection chamber 140 can maintain the consistency of the spring height of the metal terminal 130, preventing the inconsistent spring height of the metal terminal 130 when the external device is inserted into the connection chamber 140, which could cause poor contact of some metal terminals 130.

[0048] Please refer to the attached document. Figure 10 The second contact end 132 of the upper metal terminal 133 in the connection chamber 140 protrudes from the first surface 1222 of the lower part 122, and a movable hole 1221 is provided in the corresponding lower part 122, and the second contact end of the upper metal terminal is movably disposed in the movable hole 1221.

[0049] In specific implementation: the second contact end 132 of the upper metal terminal 133 and the second contact end 132 of the lower metal terminal 134 are disposed in the connection chamber 140, and the second contact end 132 of the upper metal terminal 133 protrudes from the first surface 1222 of the lower part 122. The second contact end 132 of the lower metal terminal 134 is disposed on the first surface 1222 of the lower part 122, and a bent portion is provided on the side of the lower metal terminal 134 near the second contact end 132, which is embedded inside the main body 120. A movable hole 1221 is provided in the lower part corresponding to the second contact end 132 of the upper metal terminal 133. The movable hole 1221 is mainly used for the movement of the second contact end of the upper metal terminal. When an external device is inserted, the second contact end 132 of the upper metal terminal 133 can move in the movable hole 1221 to avoid friction or collision between the second contact end 132 of the upper metal terminal 133 and the main body 120, which would cause wear or deformation of the second contact end 132 of the upper metal terminal 133. By fixing the upper metal terminal 133 to the upper part 121 and the lower part 122 on the main body 120, the second contact end 132 of the upper metal terminal 133 can maintain the consistency and stability of the spring height of the metal terminal 130 in the connection chamber 140, thereby ensuring the reliability of the contact.

[0050] Please refer to the attached document. Figures 3-4The upper part 121 and the lower part 122 are Z-shaped, and a fixing post 1211 is provided on the upper part 121 near the first contact end 131.

The main body 120 is connected and fixed to the preset plate end through the fixing post 1211.

[0052] Please refer to the attached document. Figure 3 The fixing post 1211 extends downward from the bottom of the upper part 121 and is lower than the height of the lower part 122.

[0053] In specific implementation: the fixing post 1211 is disposed on the lower surface of the upper portion 121 near the first contact end 131, and is located on both sides of the lower surface of the upper portion 121. The fixing post 1211 extends vertically downward, and the height of the extension is less than the height of the lower portion 122. The fixing post 1211 and the upper portion 121 are integrally formed. The first contact end 131 of the metal terminal 130 is disposed outside the main body 120, and is connected to the preset plate end through the first contact end 131. The fixing post 1211 disposed on the main body 120 further enhances the stability of the connection between the connector and the preset plate end.
