With the rapid development of electronic technology, USB connector interface which is widely used in electronic computers and mobile phones is also an exception.

Before the advent of the USB interface, there were many kinds of interfaces on the computer. Such as the previous serial mouse, keyboard of PS/2 interface, parallel port of connecting serial game equipment and pin printer, etc.

These interfaces are characterized by not only large size, but also slow transmission rate.

With the development of technology, the first generation of USB 1.0 interface came out in 1996. In the early stage, the support of windows system was not enough. Lack of software and hardware support, although early computers were equipped with USB interface, but because of poor compatibility, USB devices are scarce and mostly unused.

Until 1998, two years later. With the advent of USB version 1.1, Microsoft began to build a support module for USB interface in Windows 98 system, which supports simultaneous connection of multiple devices, and has a real "plug and play" feature. The speed has also reached 12Mbps, which is about 100 times faster than the standard serial transmission rate. Since then, USB devices have been widely favored by peripheral manufacturers. USB interface devices have gradually entered thousands of homes, and are gradually accepted and known by people.


With the human footsteps into the new century, USB devices have also entered the era of USB 2.0. USB devices not only greatly improve the transmission rate, but also enrich the form of interface. For example, common A-port, B-port used in printing equipment, new C-port used in mobile devices, in addition, there are micro-USB interface, Mini-usb interface and so on. As a result, USB has really entered a brilliant period of rapid development.

USB connector

1. Supporting hot swapping. In this way, when users use external devices, they can directly insert these USB cable devices into the USB interface for direct use without restarting the computer.

2, easy to carry. Most USB devices are small, light and thin. For example, the U disk equipment is commonly used.

3, standard unification. Previous computers have a variety of interfaces, but after the emergence of USB connector interface, the original standard is not uniform for all kinds of devices, if PS/Q mouse, keyboard and so on have adopted a unified USB interface.

4. Multiple devices can be connected. At present, a computer on a personal computer often has multiple USB interfaces, which can connect several USB devices at the same time. It greatly improves the convenience of equipment use.

After the emergence of USB interface, the U-disk eliminated the traditional 1.44-inch floppy disk and made the CD-ROM "glorious retirement". The number of CD-ROM drives used is also countable. Originally, the computer was broken, and the system CD-ROM was an inseparable device. Now, a small USB boot disk has been completed, and it is faster and better to use.

Nowadays, USB devices are not only becoming brilliant, but also popular, such as Wi-Fi adapters, wireless mice, keyboards and so on. It makes our computers more convenient to use, and the data transmission rate is higher. The old interfaces on desktops and notebooks themselves are beginning to be phased out. USB interface has begun to profoundly affect our lives, but also makes us more and more convenient.

In the past, most connector suppliers made more use of China's low production costs, but now they are thinking more about how to serve this emerging market. The answer it gives is to transform the original "Made-in-China" model into "Made-in-China" model.


Connector has business departments in different industries in the global framework. It chooses global headquarters including household appliances, automobiles, data communications, etc. to form a functional "headquarters ecological chain" with China regional headquarters, R&D and advanced technology development center, and production plants.






On the one hand, it aims to better serve Chinese customers and partners and respond to local business needs in a timely manner. On the other hand, it is in the most active electronic component market in the world, radiating global business. In the eyes of connector manufacturers, the Chinese market is not only huge and developing rapidly, but also high-quality partners and new business opportunities like millet, Huawei and ZTE. Customers in China are characterized by being "fast" and paying close attention to the speed of innovative products and solutions, which forces TE to localize its business in order to improve service efficiency.


Similarly, several major international connector suppliers, including Molex, FCI and Amphenol, are also laying heavy emphasis on China's market. Taking Molex as an example, it chose to set up its largest factory in Chengdu, deploying more than 185,000 square meters of manufacturing equipment and more than 20,000 employees to compete for the market, emphasizing that China is the complex element of Molex. Devices and components are at global R&D centers.


Of course, Chinese manufacturers have not abandoned this good business, electronic components manufacturers in the medical, military, network and other fields have a considerable degree of penetration, and even emerged in the international market. This is also an important reason why connector manufacturers and other international manufacturers have to go all out to try to use technological advantages to gain market voice. "Strong local companies will be the best partners." Rather than competitors, we prefer to call domestic enterprises as partners, and use their resources and channels in the domestic market to land the connector technology in the future.


In the future connector market, Yachuang Electronics hopes to discuss with more partners a place in this new era of information Internet.


 

    

       USB is the abbreviation of Universal Serial Bus in English, which means "Universal Serial Bus" in Chinese. It is not a new bus standard, but a new interface technology applied in PC field. As early as 1995, there were already PC with USB interface, but due to the lack of software and hardware support, these PC's USB interface is unused. After 1998, with Microsoft's built-in support module for USB interface in Windows 98 and the increasing number of USB devices, USB interface has gradually entered the practical stage.

      USB uses a four-pin plug as the standard plug. With this standard plug, all peripherals can be connected in the form of chrysanthemum chain without loss of bandwidth. USB standard divides USB into five parts: controller, controller driver, USB chip driver, USB device and customer driver for different USB devices.

      USB needs the support of host hardware, operating system and peripherals to work. At present, the main board generally adopts control chipset supporting USB function, and also installs USB interface slot. Windows 98 and above operating systems have built-in support for USB interfaces (but Windows NT does not yet support USB). At present, there are many USB peripherals such as digital cameras, digital speakers, scanners, keyboards, mice and so on.

      With the popularity of a large number of personal computers supporting USB, it is a general trend that USB gradually becomes the standard interface of PC. The latest PC almost 100% supports USB. On the other hand, devices using USB interface are also developing at an alarming speed. At present, we use the USB 1.1 standard interface, its transmission speed is 12 Mbps.

USB 2 standard

     USB 2.0 increases the speed of data transmission between devices to 480 Mbps, about 40 times faster than the standard of USB 1.1. The biggest advantage of the speed increase for users is that users can use more efficient external devices, and peripheral devices with multiple speeds can be connected to USB 2.0 lines, unlike USB 1.1. In the era, because of the high bandwidth, more devices do not need to worry about the bottleneck effect of data transmission. USB 2.0 can use the same specifications of cables in the original definition of USB, and the specifications of connectors are exactly the same. It also maintains the excellent features of USB 1.1 under the premise of high speed, and guarantees downward compatibility.

Type-C base occupies a large share in the connector market. The main function of Type-C base is to provide power charging and data transmission for equipment. How much do you know about the advantages and disadvantages of Type-C base? How much do you know about the application areas of Type-C mothers?

Advantages of Type-C Motors

1. Extensibility. Type-C base is suitable for all kinds of USB devices.

Domestic connector manufacturers have the following advantages:

(1) Cost and service advantages China's domestic labor market is lower than Europe, America, Japan and Taiwan's labor costs, China's domestic connector business managers localization, lower costs; Europe, America, Japan, including Taiwan's enterprises although part of the plant is located in China, but by the company's culture, business philosophy and management internationalization. Affected, the unit output labor cost still has a certain gap. Domestic enterprises still have obvious advantages in service concept, delivery cycle and response speed.

(2) At present, more than one third of the global connector market is located in China. In 3C and automobile market, Chinese system manufacturers have gained some influence in the global market. Close matching and tracking services can help domestic connector manufacturers to further expand their advantages in the future competition pattern.

(3) The technical gap is narrowing gradually in the 3C field, one of the technical barriers of connectors is high frequency. Domestic enterprises have made breakthroughs in the fields of USB socket, HDMI connector and DP.

For the manufacturing industry, how to improve the production efficiency of products is a problem that every enterprise is studying. The production efficiency of products on the assembly line will be affected by production managers, production equipment, material preparation, operation methods and working environment.For example, the material cost of wire harness processing is very high, but the profit is very low. Many enterprises have trouble in improving the efficiency of wire harness processing. As a manufacturer of connectors and connectors, how to improve the productivity of products? Xiaobian find some information, the following to share with you!

1. In terms of Technology

Enterprise production technology is the source of quality and efficiency. Mature processing technology and design precision of moulding die directly affect the quality and efficiency of moulding, that is, using better production technology, machinery, automation equipment and so on.

Two. In terms of staff

Mobilize the enthusiasm and enthusiasm of production workers, make employees consciously devote more energy to production, give full play to their maximum potential, reduce the invalid time of employees, strictly implement rules and regulations, establish reward and punishment mechanism, etc.

Three. In terms of machinery and equipment

Relevant persons in charge should do a good job in the maintenance of forming machines and moulds, improve the production speed and rotational rate of equipment, reduce standby time, do a good job in daily maintenance, reduce failure time and so on.

Four. Raw materials

Managers should do a good job of production incoming material inspection to ensure that the materials put into production are qualified, reasonably divide the material placement area, less time to find materials, and improve production efficiency.

Five. In terms of procedure

Production line managers should arrange production processes reasonably and effectively, prevent repetitive operations, handle bottleneck processes reasonably, arrange production plans reasonably, and avoid frequent replacement of product production.

Six. In terms of the environment.

Enterprise production should create a good working environment, working atmosphere, so that employees have a comfortable working environment and a good mood, reduce the workers'work fatigue and job disgust.

Seven. In terms of institutional management.

An enterprise has a standardized and procedural system, which is the fundamental guarantee to build a good production team. On the basis of a formal and standard process system, all production teams must be trained and formed good habits in their daily work, and the enterprise itself must have strong technology and excellent style of work.

I believe that not too many people will pay attention to the details of the use of the problem, in fact, whether in the work or study of the use of connectors need to be correctly used and saved to avoid some unnecessary troubles, about the use of connectors note the following, please take a look.

When we buy connectors or online shopping goods, we first check whether there is obvious damage after the packaging, see that there will be even damage to the connector itself, and so on, to ensure that he sees that the connector is intact, so as not to affect our later use of connectors.

When we don't need connectors for the time being, don't put them in disorder. Especially in the sunshine, equipment or high temperature environment, long exposure will lead to quality problems, even if there are other faults when we use them again, so don't put connectors in a safe place.

At the same time, we should pay attention to whether chemicals in the environment, connectors will corrode, so the outer metal protective layer will lose its protective effect, resulting in damage to the internal current line, without the normal function of electricity, it will become waste products. In order to avoid collisions with other objects during moving, it is better to remove them after moving. In fact, life needs to be taken care of, even for the use of very small items.

The success of the research and development of Type-C interface technology can be said to be a breakthrough in the field of electronics. USB Type-C interface has never been less popular since its inception. At present, there are many types of smartphones and notebook computers and other electronic products using USB Type-C interface for data transmission and charging connection is very common. Nowadays, with the exhaustion of energy on the earth, new energy electronic products usher in spring. New energy automobiles are also widely used. At present, the USB Type-C interface is still relatively few in the on-board charging electronic products of automobiles, which usually appears as a standby interface.

Why is the demand for vehicle electronics so high that it has not been designed with the USB Type-C interface standard? Even though many smartphones are designed and manufactured with Type-C interface, it is still not fully popular in so many electronic products, and the USB Type-C interface has not yet reached the unification of interface standards. This also limits the application of USB Type-C interface in vehicle electronic products to a certain extent, so many vehicle electronic charging products are still designed with USB-A to USB Type-C data line interface standard.


Why do we need to design and support the USB Type-C interface standard for vehicle charging products? Nowadays, USB Type-C interface connector adapter has become the standard trend of interface design. There are three advantages of using USB Type-C interface in vehicle electronic products:

1. Because the size of USB Type-C base is much smaller than that of current USB-A base, we can make the volume of on-board electronic products very small. By measuring and calculating, the volume of USB Type-C base is less than a quarter of that of conventional USB-A base. In the case of the same power design, the vehicle charging products designed by using USB Type-C output interface will be more exquisite and compact in appearance.


2. In the case of the same volume of electronic products, the vehicle charging products designed with USB Type-C interface will save more internal space and facilitate the arrangement and connection of internal circuits and electronic components, thus improving the output power of the vehicle electronic charging products and realizing no pressure on USB PD devices such as mobile phones and laptops. Charging and data transmission.

3. Nowadays, the electronic products of USB Type-C interface connectors are becoming popular, but at present, the vehicle electronic products market of USB Type-C interface is still in the blank stage, so the market prospect of the vehicle charging products of USB Type-C interface connectors at this stage is very promising. Nowadays, the rise of new energy vehicles and the vehicle electronic products are rising. Products also need USB Type-C interface to realize their potential application advantages.

   Nowadays, with the increasing demand of the vast number of users, different brands and different types of connectors appear around us, providing us with a variety of choices. As users, we not only need to choose connectors according to our own needs, but also need to have a detailed and in-depth understanding of the quality of connections, brand and reputation of the companies that produce and sell connectors. So how should connectors choose?

    First of all, there are many kinds of connectors. As users, they need to understand their needs and then choose connectors that can meet their needs. Whether it is terminal, special needle arrangement, Jane or special steak mother, different connectors have different functions. As user I

   In choosing connectors, the first thing we need to measure is whether they can meet our needs. Only those connectors that can play a significant role in meeting our needs are worthy of our trust and choice. This is the first criterion that we should measure when choosing connectors.

   Secondly, the quality of connectors of different brands is a condition that can not be ignored. With the increasing demand of users, now different brands of connectors appear around us, enriching our choices. But for users, the key criterion to judge whether a brand connector is trustworthy is whether its quality is trustworthy. This is also an important reason why more and more users will have a detailed understanding of its brand reputation and reputation when choosing connectors.

   Third, choosing connectors requires understanding of the company that produces and sells. Different manufacturers and sales companies often have different standards for connector production, which requires us to have a detailed understanding of them as users. For users, the main purpose of choosing connectors is to make them work. Therefore, the understanding of connector manufacturers and sales companies can not be ignored.

While maintaining compatibility with USB 2, the new USB 3 also provides the following enhancements:

It greatly improves the bandwidth - up to 5 Gbps full duplex (USB2.0 is 480 Mbps half duplex), realizes better power management, and enables the host to provide more power for the device.

So as to realize the application of USB- rechargeable batteries, LED lighting and mini fans.

Enables the host to identify devices faster.

The new protocol makes data processing more efficient.

USB 3 can transmit large capacity files (such as HD movies) at storage rates defined by memory devices.

For example, a flash driver with USB 3.0 can transfer 1GB of data to a host in 3.3 seconds, while USB 2.0 takes 33 seconds.

Driven by the increasing demand for resolution and storage performance of consumer electronic devices, it is hoped that broadband Internet connection will enable broader media applications. Therefore, users need faster transmission performance to simplify downloading, storage and sharing of large amounts of multimedia content. USB 3 plays a crucial role in providing consumers with the simple connectivity they need.

When used in consumer devices, USB 3 will solve the problem that USB 2 is unable to identify battery free devices. The host can slowly reduce the current through USB 3.0 to identify these devices, such as mobile phones whose batteries have broken down.

     Since Apple's New Macbook was equipped with Type-C interface the year before last, more and more mobile phone manufacturers have begun to follow up. It is the development route of Type-C in smartphones that penetrates from high-end to low-end step by step. At present, the new mainstream flagship models on the market have fully started using the USB Type-C interface.

     It is understood that currently on the market Lexus super mobile phone series, millet series, Moto Z/M, LG G5, Jinli M5 Plus, ZUK Z1, Huawei P9 series, ZTE AXON Skycraft MAX, one plus mobile phone 2, Jinli S8, Meizu Pro 6S/5 all use Type-C interface. It is also rumoured that Apple's 8 next year will also use the Type-C interface.


      Whether Apple 8 will use the Type-C interface is not mentioned for the moment, but as far as the best-selling mobile phones are concerned, Type-C will become the mainstream. The Type-c interface accounted for 25% of China's best selling mobile TOP 20 in November. The 5 best-selling mobile phones with Type-c interface are priced over 2000 yuan except for the 2 Kings.

      Based on the above data, mobile phones selling for more than 2000 yuan in the first half of 2017 will fully configure the Type-c interface, and mobile phones selling for more than 1000 yuan in the second half of 2017 will fully configure the Type-c interface.

So why Type-C interface will be sought after by mobile phone manufacturers? Let's analyze it. Because Type-C interface can support data, audio, video and charging at the same time, it can also be compatible with Display Port, HDMI, MHL and other mainstream high-definition video interface standards. Thunderbolt 3-compatible Type-C can provide up to 40 Gbps speed, making dual 4K HD transmission possible. Therefore, Type-C will undoubtedly become the best choice for future video interfaces. High-definition display, flat panel TV, VR/AR devices will farewell to the coexistence of multiple interfaces, with the help of Type-C to achieve the unification of audio and video and power supply. On the phone, you can replace the 3.5 inch headphone interface.

       In addition, the Type-C interface can bring the convenience of forward and backward interpolation, and the maximum flow defined by the Type-C interface connector is 5A, while retaining the flow definition of 10A to meet the fast charging requirements, which is also what the terminal manufacturer sees. At the same time, Type-C, which integrates charging, data and audio-video interface functions, is very powerful, and the establishment of the ecosystem will form a situation in which the interface will spread all over the world. In view of this, from the top-down point of view of the industrial chain, the giants of USB Association, standard-setting, interface chips, factories and consumer terminals all spare no effort to promote the popularization of USB-C.

        It is understood that the mainstream mobile phone suppliers Foxconn, BYD, Dafu Technology and other enterprises are also in the layout of production Type-C interface related products, and has continued to ship. Weifeng Electronics, TI, NXP, Cypress, Analogix and other chip manufacturers have released a number of high-speed data transmission, charging and video interface chips. The latest versions of apple OS, Google Android and Microsoft WP platform all support Type-C.
