Description

Pin structure of a new USB3.0 connector

Technical field:

The utility model relates to the technical field of data transmission connectors, in particular to a novel pin structure of a USB3.0 connector.

Background technique:

The USB connection method is a commonly used and convenient connection method in the connection between computers and peripherals. After continuous research and development by researchers, it has developed from the era of USB1.0/1.1 and USB2.0 to the current era of USB3.0. The known USB2.0 is designed with 4 pins, and USB3.0 adopts a 9-pin design in order to be backward compatible with USB2.0, and the shape and definition of the 4 pins are exactly the same as those of the existing USB2.0 pins. 5 pins are specially designed for USB3.0. In terms of the arrangement of the above nine pins, the existing USB3.0 technology is shown in Figure 1, which mainly adopts a vertical arrangement, that is, a row of 4 pins for USB2.0 and a row of 5 pins for USB3.0. The production and molding of the pins of the method requires two metal substrates, the material cost and production cost are high, and the main difficulty is the difficulty and high cost of automatic welding.

Utility model content:

The purpose of the utility model is to overcome the above disadvantages of the prior art, and provide a novel USB3.0 pin structure to improve production efficiency, save costs and improve performance.

The technical solution adopted by the utility model to achieve its purpose is: a new pin structure of the USB3.0 connector, including USB2.0 pins and USB3.0 pins, the USB2.0 pins and USB3.0 pins are arranged side by side, And the terminals of the two groups of pins are arranged in a staggered manner, and a transverse gap is provided between adjacent terminals.

The end of the ground terminal of the USB3.0 pin is connected to the welding area, and the welding area extends laterally and covers all lateral ranges of the terminal.

After the utility model adopts the above-mentioned structure, two sets of metal terminals can be punched and formed on the same metal substrate at one time, which not only saves the stamping time once, but also saves nearly half of the consumed substrate compared with the original required substrate. ; In addition, the pin structure of the utility model is adopted to facilitate the automatic welding operation of the USB3.0 connector and reduce the manufacturing cost; through the extension design of the grounding terminal, it is possible to timely eliminate the problem caused by the relatively small distance between the 9-pin side-by-side terminal and the terminal. Electromagnetic interference, to ensure the performance of the USB3.0 connector.

Description of drawings:

FIG. 1 is a schematic structural diagram of pins in an existing USB3.0 connector;

Fig. 2 is a three-dimensional structural schematic diagram of the pins of the USB3.0 connector of the present invention;

Fig. 3 is a schematic plan view of the pins of the USB3.0 connector of the present invention.

Detailed ways:

Below in conjunction with specific embodiment and accompanying drawing, the utility model is further described.

As shown in Figure 2, it is a pin structure formed by a substrate 1 after one stamping and forming, and is divided into two groups, one group is USB2.0 pin 11, the number is 4, and one group is USB3.0 pin 12 , the number is 5, because the two groups of pins are formed on the same substrate 1 at the same time, so the two groups of pins are arranged side by side, and the terminals of the two groups of pins are interlaced with each other, and there is a certain Lateral gap 13.

Furthermore, in the 5 pins of USB3.0, the ground terminal 120 is connected to the welding area 14 of the substrate 1, and the welding area extends laterally and covers the lateral range of the 9 pins, so that the gap between the terminals can be eliminated in time. Electromagnetic interference due to small relative spacing.

Apparently, according to the technical revelation of the present invention, multiple sets of stitch combinations can be stamped on a strip substrate, as shown in FIG. 3 , which can save time and cost and improve production efficiency.
