What is the meaning of the USB connector to be gold plated?

Recently, in the customer email of Konnra Electronics, many customers were found to consult “What is the role of the metal plating of the USB connector socket?” In order to facilitate the user's inspection, Konnra Electronics engineers specially compiled this document and summarized the USB. Connector socket metal plating function.

The role of the metal plating of the USB connector socket is mainly manifested in five aspects, as follows:

1. The coated USB socket is not easily oxidized and vulcanized.

2. It can improve its mechanical properties and enhance wear resistance to a certain extent.

3. Optimize the electrical performance of the USB socket, establish and maintain the impedance of the USB socket.

4. The precious metal coating is relatively simple to contact the metal that produces the interface, maintaining the stability of the contact interface impedance.

5. The surface of the general metal plating layer is covered with an oxide film to prevent the oxide film from rupturing when the USB socket is mated, ensuring that the contact interface is not oxidized.

Konnra Electronics engineers pointed out that the USB socket terminal plating function is also beautiful, protective, extending the life of the product, coating the surface of the product with corrosion-resistant materials. Mechanical or engineering properties also improve the lubricity of the product and the strength of the product, including Improve the electrical conductivity of the product, improve the reflectivity of light, reduce the contact resistance, improve the weldability of the product, and the like.

USB connector

To understand the usb interface, you must first understand its concept. In English, usb is the abbreviation of Universal Serial Bus, translated into Chinese is the meaning of "universal serial bus". It is not a new bus standard, but a new interface technology for PC applications. In 1995, the usb interface was already used on the PC, but due to the lack of software and hardware support, the USB ports of these PCs were idle. Until 1998, with Microsoft's built-in support module for USB interface in Windows 98, and the increasing number of USB devices, the USB interface gradually entered the practical stage.

USB uses a 4-pin plug as a standard plug. With this standard plug, all peripherals can be connected in a daisy chain without losing bandwidth. The USB standard divides USB into five parts: controllers, controller drivers, USB chip drivers, USB devices, and client drivers for different USB devices.

USB requires support from the host hardware, operating system, and peripherals to work. At present, the motherboard generally adopts a control chipset that supports USB functions, and also has a USB interface slot. Windows 98 and above have built-in support for the USB interface (but Windows NT does not yet support USB). At present, there are many USB peripherals such as digital cameras, digital speakers, scanners, keyboards, and mice. With the popularity of a large number of USB-enabled PCs, USB has gradually become the standard interface for PCs. The latest PCs support almost 100% of USB, and devices that use USB interfaces are also growing at an alarming rate. Currently we are using the USB1.1 standard interface, which has a transmission speed of 12Mbps. USB 2.0 standard The seven vendors, COMPAQ, Hewlett Packard, Intel, Lucent, Microsoft, NEC, and PHILIPS, have jointly developed the USB 2.0 interface standard. USB 2.0 increases the data transfer speed between devices to 480Mbps, which is about 40 times faster than the USB 1.1 standard. The biggest benefit for users is that they can use more efficient external devices and have multiple speeds. Peripherals can be connected to USB 2.0 lines, unlike the USB 1.1 era, because high bandwidth allows more devices to worry about bottlenecks during data transmission. USB 2.0 can use the same specifications of the cable in the original USB definition. The specifications of the connector are also the same. Under the premise of high speed, the excellent features of USB 1.1 are maintained, and backward compatibility is also guaranteed.

After reading the above, you should have a basic understanding of the usb interface connector related knowledge, and more related to the usb interface, Konnra Electronics engineers will continue to archive for you.

The most comprehensive interpretation of the USB Type-C connector standard

USB Type-C (USB-C) is the latest USB interface standard, and its application in various fields is rapidly spreading. This article describes the performance characteristics of the USB-C connector, as well as the USB-C related USB PD and USB 3.1 second generation and other related power and data transmission specifications and features, while using CUI's USB-C interface products for For example, the selection of USB interface products is introduced to help developers understand the USB-C standard and select the high-quality USB-C interface or cable assembly.

"Faster, higher, stronger" is our familiar Olympic motto. If you use this adage in the electronics industry, it should be "faster, smaller, easier to use" - this is the new standard for USB connectivity. Shouting.

As you may have already seen, the latest USB Type-C (USB-CTM) ports are widely used in the next generation of computing products currently on sale, and this trend is expected to be further strengthened in the future, as USB-C is available through a single cable. A unique ability to connect to transmit data, power, and even audio.

Market analyst firm ABIResearch believes that we have reached the critical point of USB Type-C commercial; by 2021, global shipments of smartphones equipped with such USB connectors are estimated to reach 830 million units.

With a width of only 9mm and a height of only 3.5mm, this connector is much smaller than previous generations of connectors, allowing device manufacturers to develop smaller devices. Its advent is just the right time to perfectly meet the needs of emerging products, such as home automation and IoT devices, including smart sensors that work seamlessly with this smaller, simpler, latest connector package.

Unusable ease of use

Cables for USB-C applications can be plugged in from either end to meet the power requirements of devices such as laptops, eliminating the need for users to carry multiple cables for different purposes.

This versatility stems from a more complex structure inside the connector (Figure 1). First, it has more wires. USB Type-A and Type-B connectors require four or five wires - unlike them, USB-C includes 24 contacts, allowing bidirectional insertion, and supports four power and ground pairs, as well as two signal pairs. . In addition, its rated durability has increased to 10,000 insertions and exports, a significant increase from the previous version of 1,500 plugs.

The USB-C's power and ground pair are rated for voltages up to 20V, current ratings are increased, and the total rating is 5A, providing up to 100W of power transfer over a single USB-C connection. In addition, each data pin pair can manage data transfer rates of up to 10 Gbps, which means the connector's total transfer capacity reaches 20 Gbps.

Faster data and higher power transfer

The latest data and power specifications of USB-IF force us to significantly increase the USB-C's transmission capabilities, especially in USB Power Delivery (USB PD), USB 3.1 Generation 2 and recently finalized USB 3.2 high-speed data specifications:

USB PD utilizes all four power and ground pairs to maximize the USB-C's 100W power transfer capability

USB 3.1 Generation 2 uses a set of data channels to define a 10Gbps transfer rate

Similarly, USB 3.2 controls two sets of 10 Gbps data channels to maintain transmission rates of up to 20 Gbps.

Conceptually, distinguishing the USB-C standard (physical connections only) from USB PD and high-speed data specifications (including USB 3.1 Generation 1 (SuperSpeed) and USB 3.1 Generation 2 (SuperSpeed +), and USB 3.2) Opening is very important.

For example, although the USB-C connector is designed to support the USB PD standard, to negotiate and manage power delivery to interconnected devices, a USBPD-compatible host controller must still be available. In addition, the cable must be configured to support this standard.

USB PD not only increases power, it also facilitates bidirectional power transfer, which greatly increases the flexibility of charging and powering user equipment. On this basis, since the USBPD can perform power negotiation through the VBUS connection instead of using a data connection, it can simultaneously transmit power and data streams.

Table 1 shows the upgrade process of USB transport capabilities in recent generations.

In terms of high-speed data specifications, the second generation of USB 3.1 defines data and power signals, but does not specify physical connections. This allows us to connect USB 3.1 Gen 2 devices with conventional Type-A or Type-B connectors and cables and achieve data transfer rates of 10 Gbps as long as they have sufficient current, voltage and signal integrity characteristics. Similarly, we can use a simple hardware adapter to provide traditional connectivity standards such as USB 2.0 using a USB-C connector.

High quality USB-C connector selection

Obviously, not all USB-C connectors or cable assemblies are “born equal”, and premium products offer better performance and more reliable communication over longer cables.

In addition to considering the quality of materials and USB-C connectors for future products, designers can choose between two versions of Type-C sockets, see Figure 2. Traditionally, standard SMT mounting sockets are located above the PCB. In this case, however, the total assembly height is the sum of the PCB thickness and the connector height. Alternatively, the intermediate mount connector can be mounted to the recess in the PCB; although this reduces the overall assembly height, the intermediate mount connector does not allow for signal lines to be routed under the connector.

Summary of this article

In the consumer electronics market, the use of USB Type-C connectors is rapidly gaining popularity. To meet this ever-increasing demand, electronic component manufacturer Konnra Electronics offers a range of high quality USB Type-C plugs and sockets, including SMT and intermediate mounting types. These connectors are designed to achieve the communication rates defined in the USB 3.1 Gen 2 specification while meeting the current and future needs of designers.

USB 3.2 standard can be used on PC during the year

According to the latest USB naming convention published by USB-IF, the original USB 3.0 and USB 3.1 will no longer be named. All USB standards will be called USB 3.2. Of course, considering compatibility, USB 3.0 to USB 3.2 are called respectively. USB 3.2 Gen 1, USB 3.2 Gen 2, USB 3.2 Gen 2x2.

For the new USB 3.2 Gen 2x2 naming, it uses all the data pins up and down to double the data speed. So, when will the USB 3.2 Gen 2x2 device be used?

The USB-IF standards group revealed that the USB 3.2 Gen 2x2 controller will be available later in 2019, meaning that consumers will be able to use the latest standards in their desktops during the year. In other words, consumers can use existing devices by purchasing peripherals that support the USB 3.2 Gen 2x2 standard.

For the USB socket and the standard big name, including USB 3.0 and USB 3.1, after the unified system, everyone is called USB 3.1. For example, in July 2013, after USB 3.1 was released, USB-IF called all USB 3.X USB 3.1, including USB 3.1 Gen 1 and USB 3.1 Gen 2. Now that USB 3.2 has been released for a while, USB-IF has to do something new, and that is the reunification of the USB 3.X series.

The news is organized by Konnra Electronics.
