It is widely used in information and communication products such as personal computers and mobile devices.

[0003] USB has developed from version 1.0 to version 4.0, among which versions 1.0, 2.0 and 3.0 have similar appearances. USB1.0 has been gradually replaced by USB2.0 and USB3.0. Currently, USB2.0 and USB3.0 are the two most commonly used interfaces on large devices in the market. USB2.0 and USB3.0 require the use of matching 2.0 and 3.0 soldering plates to connect the connector circuit to the device PCB circuit. The soldering plate acts as a bridge between the connector and the device PCB circuit. Due to the pins between the soldering plate and the connector, There are differences in the size and shape of the connection parts. USB2.0 uses 4 pins and USB3.0 uses 9 pins. Currently, the 2.0 connector can be directly soldered to the 2.0 soldering board, while the 3.0 connector requires an adapter to connect to the 3.0 soldering board. In other words, the 3.0 connector cannot be directly soldered to the 3.0 soldering board, and the 2.0 connector cannot be directly soldered to the 3.0 soldering board. The two versions of USB2.0 and USB3.0 connectors require the use of 2.0 and 3.0 soldering boards respectively, resulting in the problem of a large variety of materials and increased material costs.

[0022] See also Figure 1-8The utility model provides a technical solution: a 2.0 and 3.0 universal USB connector, comprising an insulating support plate 1, four first conductive strips 6 and five second conductive strips 7 are evenly and equidistantly laid on the front side of the upper end of the insulating support plate 1, the first conductive strip 6 is located between two adjacent second conductive strips 7; the front end of each first conductive strip 6 is fixedly connected to a first pin 10, the front end of each second conductive strip 7 is rotatably connected to a second pin 11, the first pin 10 is located between any two adjacent second pins 11, the spacing between the first pin 10 and the adjacent second pin 11 is equal, and the diameter of the first pin 10 is equal to the diameter of the second pin 11; the second pin 11 and the second conductive strip 7 adjacent to its rear are rotatably connected with a fine needle 17, and the left and right ends of the fine needle 17 are rotatably connected with the insulating support piece 13. The rear end of the second pin 11 is fixedly connected to the lower end of the adjacent insulating support piece 13 at a vertical angle of 90 degrees. The upper ends of the multiple insulating support pieces 13 are fixedly connected with insulating horizontal strips 12. The maximum rotation angle of the fine needle 17 is 90 degrees. Four contact strips 5 are laid on the rear side of the upper end of the insulating support plate 1. The main control circuit 8 is laid on the middle side of the upper end of the insulating support plate 1. The main circuit 8 is electrically connected to the contact strip 5, the first conductive strip 6 and the second conductive strip 7 respectively. The first conductive strip 6 is electrically connected to the first pin 10, and the second conductive strip 7 is electrically connected to the second conductive strip 7. The strip 7 is electrically connected to the second pin 11; the front end of the insulating support plate 1 is provided with a soldering plate 2 located below the first pin 10 and the second pin 11, and the upper end of the soldering plate 2 is electrically connected to nine soldering points 9, and the first pin 10 and the second pin 11 respectively correspond to the upper ends of the adjacent soldering points 9 below them; the entire USB connector is divided into two major parts in terms of structural layout: the insulating support plate 1 and the soldering plate 2. The contact strip 5, the main control circuit 8, the first conductive strip 6, the second conductive strip 7, the first pin 10, the second pin 11, and the fine needle 17 are pre-laid on the insulating support plate 1, and the outer periphery of the insulating support plate 1 is provided with a metal shell 3, and the metal shell 3 is inserted into the outer surface of the insulating plate To surround the contact strip 5 and the main control circuit 8, the insulating support plate 1 is placed above the welding plate 2. The front sides of the left and right ends of the metal shell 3 are fixedly connected to the left and right sides of the rear end of the welding plate 2 through detachable reinforcement fasteners 4, so that the reinforcement fasteners 4 are buckled into the upper end of the welding plate 2. The reinforcement piece plays the role of reinforcing the connection between the metal shell 3 and the welding plate 2 into one piece, so that the first pin 10 and the second pin 11 are simultaneously aligned with the upper end of the corresponding soldering point 9 below them, and the first pin 10 and the second pin 11 are aligned and assembled with the upper end of each corresponding soldering point 9 on the welding plate 2, so that the first pin 10 and the second pin 11 are firmly welded to the corresponding soldering point 9.

[0023] When the first pin 10 and the second pin 11 are aligned side by side and placed in the same horizontal plane, the first pin 10 and the second pin 11 are exposed at the same time, and the first pin 10 and the second pin 11 extend out at the same time to form six conductor paths, and the insulating support sheet 13 is placed vertically, and the insulating cross bar 12 is used to connect the upper ends of multiple insulating support sheets 13 into one body, and the insulating support sheet 13 and the corresponding second pin 11 are fixedly connected to each other at a ninety-degree vertical angle. The upper ends of the multiple insulating sheets lift the insulating cross bar 12 upward above the insulating support plate 1, and a distance is maintained between the insulating cross bar 12 and the insulating support plate 1. The left and right ends of the insulating cross bar 12 are fixedly connected to the first magnetic sheet 14, and the upper end of the insulating support plate 1 and adjacent to the rear lower part of the first magnetic sheet 14 are fixedly connected to the third magnetic sheet 16. The left and right sides of the front end of the metal shell 3 are fixedly connected to the second magnetic sheet 15. The first magnetic sheet 14 and the second magnetic sheet 15 attract each other to keep the insulating cross bar 12 fixed. This placement of the first pin 10 and the second pin 11 makes this USB connector a 3.0 version.

[0024] The iron content of the metal shell 3 is more than 15%, and the surface of the metal shell 3 is electroplated with an anti-rust protective layer. The second magnetic piece 15 can make the surface of the metal shell 3 magnetic. In this way, the metal shell 3 has magnetic conductivity, and the second magnetic piece 15 makes the metal shell 3 magnetic, which can make the second magnetic piece 15 and the surface of the metal shell 3 more firmly attracted, thereby enhancing the stability of the installation of the second magnetic piece 15, making the first magnetic piece 14 more firmly attracted to the second magnetic piece 15, and making the insulating cross bar 12 more stable.

[0025] If a USB connector of version 2.0 is needed, use tweezers or a pointed object to poke and move the insulating cross bar 12 so that the insulating cross bar 12 is moved or poke toward the metal shell 3, so that the first magnetic piece 14 is separated from the second magnetic piece 15. The insulating cross bar 12 simultaneously drives multiple insulating support sheets 13 to flip at a 90-degree angle around the adjacent fine pins 17. Multiple insulating support sheets 13 cause each corresponding second pin 11 to flip at a 90-degree angle. The insulating cross bar 12 contacts the insulating support plate 1. After the insulating cross bar 12 flips 90 degrees, the first magnetic piece 14 and the third magnetic piece 16 attract each other. After the rotation, the insulating cross bar 12 relies on the mutual attraction between the first magnetic piece 14 and the third magnetic piece 16 to maintain a fixed placement state. The insulating cross bar 12 causes the insulating support sheet 13 to change from its original horizontal placement state to a vertical upright placement state. The insulating cross bar 12 causes the insulating support sheet 13 to drive the second pin 11 to tilt up. Only four pins are left on the insulating support plate 1, and this USB connector becomes version 2.0.

[0026] If you need to restore this USB connector to its original 3.0 version, reverse the steps of moving or provoking the insulating horizontal bar 12. Use tweezers or a pointed object to move or prod it in a direction away from the metal shell 3. The first magnetic piece 14 and the third magnetic piece 16 will separate, causing the insulating horizontal bar 12 to flip in a direction away from the metal shell 3. The insulating horizontal bar 12 will then stand up each insulating support piece 13 again. The first magnetic piece 14 and the second magnetic piece 15 will attract each other. After the insulating horizontal bar 12 is reversed, it will be re-fixed by the mutual attraction between the first magnetic piece 14 and the second magnetic piece 15. After each insulating support piece 13 is stood up, the second pin 11 will be changed from a vertical upright position to a horizontal position flush with the first pin 10. At this time, the USB connector will be restored to version 3.0.

[0027] In the above technical solution, it is only necessary to flip the insulating horizontal strip 12 at a 90-degree angle directly in the direction away from or close to the metal shell 3, and the second pin 11 and the first pin 10 are placed in parallel or perpendicular to each other. Therefore, the second pin 11 is close to or away from the first pin 10, which can realize the conversion of the number of pins of the USB connector. When only four first pins 10 are placed horizontally, the USB connector is version 2.0. When the four first pins 10 and the five second pins 11 are placed horizontally at the same time, the USB connector is version 3.0, realizing the effect of free switching between version 2.0 and version 3.0. The effect of switching between version 2.0 and version 3.0 is achieved by switching the number of pins. The four first pins 10 and the five second pins 11 are evenly distributed at equal distances. There is no gap between any adjacent first pins 10 and second pins 11. The spacing is equal, the spacing between any two adjacent first pins 10 is equal, and the spacing between any two adjacent second pins 11 is equal. When only four first pins 10 are welded to the second, fourth, sixth, and eighth solder joints 9, when four first pins 10 and five second pins 11 are arranged in parallel, all nine solder joints 9 will be welded. After welding, the entire insulating support plate 1 is covered with insulating glue and the four first pins 10 and the five second pins 11 are covered. The insulating glue will stick the four first pins 10 and the five second pins 11 together for fixation. The insulating glue can also be used to cover and stick the insulating horizontal bar 12 and the insulating support sheet 13. The insulating glue makes the four first pins 10 and the five second pins 11 more secure after welding. In the process of producing the same USB connector, it is compatible with both 2.0 and 3.0 versions of materials.

[0028] Before welding, the USB connector is adjusted to the required 2.0 or 3.0 version state, and then the nine solder points 9 on the welding plate 2 are aligned with the first pin 10 and the second pin 11 and accurately welded in place. During the production process, only the same 3.0 welding plate 2 needs to be prepared to be compatible with both 2.0 and 3.0 USB pin layouts. The connector is universal for both 2.0 and 3.0 versions, so there is no need to prepare materials for 2.0 and 3.0 versions separately. Only one material is needed to produce both 2.0 and 3.0 versions of USB connectors, which is beneficial to saving materials and reducing the cost of consuming materials.
