Description

miniature electrical connector

technical field

The utility model relates to a miniature electrical connector, in particular to a miniature electrical connector in which reinforcing parts are arranged on the tongue of an insulating body to improve the strength of the tongue.

Background technique

As people's demand for convenient application of electronic products is becoming more and more obvious, it has attracted the continuous attention of various manufacturers. In order to improve the competitiveness of electronic products, manufacturers must continuously strengthen and expand the functions of electronic products. In addition to the light, thin and small appearance, its structure and transmission speed also need to be continuously increased to improve the user's convenience in operation and use.

Since electrical connectors are used to connect electronic products or between components in electronic products for signal transmission, the importance of electrical connectors in electronic products is beyond words. Therefore, how do manufacturers make electrical connectors easy to assemble during manufacturing and reduce The cost of assembly and the function of the electrical connector at the same time have become a point of competition among various manufacturers.

In electrical connectors, there is also the biggest breakthrough in USB connectors. USB (Universal Serial Bus) is a serial bus standard for connecting external devices. It is widely used on computers and is the most common specification. It can also be used on set-top boxes and game consoles, and even many industrial instruments are connected to computers through USB. USB can not only provide data transmission for peripheral devices, but also provide power supply. The On-The-Go plug-and-play feature makes it portable devices to exchange data directly.

From the very beginning, USB was the USB1.0 specification, 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. This specification is widely used in electronic products. Currently the latest USB3.0 specification increases the transmission speed to 5.0Gb/s, which is more than 10 times that of the USB2.0 specification. Because the speed is much higher than before, it has become a product to be promoted by various manufacturers in the future.

Therefore, with the prospect of USB3.0 specification products in the future, how to achieve the purpose of simple manufacturing of USB3.0 products has become an urgent problem for manufacturers to overcome.
