Electrical connector structure

The present invention relates to an electrical connector structure, and more particularly to an electrical connector structure that is applied to the USB 3.0 specification and that can increase the strength of the insulating body structure.

With the increasing demand for convenient applications of electronic products, and thus the continuous attention of various manufacturers, in order to improve the competitiveness of electronic products, manufacturers must constantly strengthen and expand the functions of electronic products, so all kinds of electronic products are oriented In addition to being thin and light, the structure and transmission speed of the model are also required to be increased, so as to improve the convenience of the user in operation and use.

Since electrical connectors are used to connect signals between electronic products or between components in an electronic product, the importance of electrical connectors in electronic products is beyond words. How can manufacturers easily assemble electrical connectors during manufacturing? , to reduce the cost of assembly, while at the same time taking into account the effectiveness of electrical connectors, has become a competition among manufacturers.

In the electronic connector, the USB connector also has the biggest breakthrough. The USB (Universal Serial Bus) universal serial bus is a serial bus standard for connecting external devices. It is widely used on computers and is the most common. Specifications can also be used in set-top boxes and game consoles. Even many industrial instruments are connected to computers via USB. USB not only provides peripheral device data transmission, but also power supply. On-The-Go plug-and-play features are more. Can make portable devices straight Exchange data.

USB was originally a USB1.0 specification from the beginning, and its transmission speed was 1.5Mb/s. In 1998, the USB2.0 specification was introduced, and the transmission speed was increased to 12Mb/s, which is widely used in electronic products. In the current, the latest USB3.0 specification will increase the transmission speed to 5.0Gb/s, which is more than 10 times that of the USB2.0 specification. Since the speed is much higher than before, it has become a product promoted by various manufacturers in the future. .

Therefore, in the future of USB3.0 products, how to achieve the purpose of simple manufacturing of USB3.0 products has become a problem that manufacturers need to overcome, and the required connection of USB3.0 products. There are a large number of terminals, so how to increase the welding strength of the USB3.0 electrical connector soldered to the circuit board of the electronic product is also one of the problems that need to be overcome at present.

Declining, so how to increase the structural strength of the insulating body in a thin and light electronic device is a problem that needs to be overcome.

It can be seen that there are still many shortcomings in the above-mentioned conventional structure, which is not a good designer, but needs to be improved.

In view of the shortcomings derived from the above-mentioned conventional structure, the creators of this case have improved and innovated, and after years of painstaking research, they finally succeeded in research and development of the electrical connector structure.

The purpose of this creation is to increase the number of fixed terminals. The overall structural strength of the edge body avoids warping deformation of the insulating body.

Another object of the present invention is to improve the welding strength of the insulating body to be fixed on the circuit board by strengthening the welded portion extended by the fixed terminal.

In order to achieve the above object, the electrical connector structure of the present invention comprises an insulating body and a flat conductive terminal fixed on the insulating body, a resilient arm conductive terminal and a reinforcing fixed terminal; the soldering terminal of the flat conductive terminal and the elastic arm conductive terminal is exposed The rear end of the insulative housing, the flat conductive terminal and the elastic arm conductive terminal are arranged in accordance with the specification of USB3.0, and the reinforcing fixed terminal is disposed on the front end and the two sides of the insulating body; wherein the reinforcing fixed terminal is formed into a crucible The font structure is embedded in the front end and the two sides of the insulating body, and the fixing terminal is arranged to avoid deformation warping of the insulating body.

In order to achieve the above other object, an exposed soldering portion is extended on both sides of the reinforced fixed terminal of the present invention, and the soldering surface of the soldering portion is substantially coplanar with the bottom surface of the insulating body, so that it is soldered and fixed on the circuit board. Therefore, according to the arrangement of the welded portion of the fixed terminal, the welding strength of the original electrical connector fixed on the circuit board can be improved.
