Micro USB cable

2020-1-24 23:41:21

For a long time, micro USB has a lot of weight in the USB market, but his position today is becoming less and less important.  Micro Usb will gradually withdraw from the mainstream application market. Look at the data interfaces of your friends ’mobile devices. They are mainly divided into two camps, one for Android TYPE C and one for Apple. Now the Type-C interface has become a trend.  .  Whether it is Micro USB, lightning or USB Type-C, Sinodec Industrial Co., ltd. Can provide customized services. Of course, we also produce the most popular USB cables in the market.

Micro USB is a portable version of the USB 2.0 standard, which is smaller than the Mini USB interface used in some mobile phones. Micro-USB is the next-generation specification of Mini-USB. It was developed by the USB Standardization Organization in the United States in 2007 by the USB Implementers Forum (USB-IF).  Completed on January 4th, 2008, Micro-USB supports OTG. Like Mini-USB, it is also 5pin. The definition of the Micro series includes Micro-B series slots used by standard equipment; Micro-AB slots used by OTG equipment;  Micro-A and Micro-B plugs, as well as cables. The unique feature of the Micro series is that they include a stainless steel housing, which is not a problem for 10,000 insertions.

Taking history as a guide to know the rise and fall, let's take a look at the development history of MicroUSB

June 2004 includes major global mobile network operators such as Vodafone, Orange, T-Mobile, O2, Telefonica in Spain, TelecomItaliaMobile, and NTT DoCoMo in Japan, as well as major players such as Nokia, Samsung, Motorola, Sony Ericsson, and LG  Mobile phone manufacturers established the OpenMobileTerminalPlatform (OMTP) organization. In September 2007, OMTP announced the global unified mobile phone charger interface standard is Micro USB. The new Micro USB specification supports USB technology on mobile devices such as mobile phones.  And it is ready for smaller and more compact portable devices in the future. Various portable devices such as mobile phones, MP4, digital cameras can be connected and communicated without going through a PC. In the future, these mobile phones will be produced by these manufacturers.  Will be committed to adopting the Micro USB standard and strive to make it a unified charging interface for future mobile phones. The use of the Micro USB interface enables one interface to be used for charging, audio and data connections.

What is MicroUSB

On the other hand, the conclusion of this agreement is also the result of the EU ’s advocacy. The EU WEEE department requires handheld device manufacturers to be responsible for waste and pollution caused by interface differences, and hopes that the agreement on unified interfaces can reduce this aspect of waste.  The European Union also recommends that new phones can be omitted because they already have a Micro USB charger when packaging. This will not only reduce waste, but also reduce packaging and shipping costs, and an interface can be used for charging and data.  Transmission can simplify various operations and is also a good thing for users.

Micro USB phone interface

The universal charger interface standard officially implemented in China on June 14, 2007 clearly stipulates the overall structure of the charger and the interface on one side. The most widely used USB A interface is used to solve both the universal charger and the mobile phone.  Can be easily connected to a computer to achieve charging or transmitting data. The essence of this standard requirement is "a USB interface is added to the transformer". The mobile phone charger is replaced by a USB data cable and a USB socket  Device, charger base can no longer be a standard configuration of the mobile phone, only a USB data cable can be used, or it can be charged directly from the PC interface. There is no relevant standard requirement for the interface on the mobile phone side.  In terms of Mini-USB, it has advantages in terms of size, electrical characteristics and plug-in times. Therefore, the Micro-USB interface is the mainstream of major mobile phones and tablet small electrical equipment before 2015

Micro USB is the standard for mobile phone chargers, and its main advantages are also many

Micro-USB connectors are smaller than standard USB and Mini-USB connectors, saving space,

With up to 10,000 mating life and strength,

The Micro-USB standard supports the current USB OTG function, that is, without a host (such as a personal computer), data can be directly transmitted between portable devices

Compatible with USB1.1 (low speed: 1.5Mb / s, full speed: 12Mb / s) and USB 2.0 (high speed: 480Mb / s),

Provides both data transmission and charging,

It is especially suitable for high-speed (HS) or higher data transmission. It is the best choice for connecting small devices (such as mobile phones, PDAs, digital cameras, digital video cameras and portable digital players, etc.).

Why are they so good that they are eliminated?

In the early years, when Android smart phones first became popular, almost all Android mobile phones used the Micro USB interface as the charging interface. Until now, although mobile devices such as mobile phones have been updated quickly, there are still many  This type of charging interface is used on mobile devices such as mobile phones, smart bracelets, and Bluetooth headsets. It is also widely used, and new mobile phones in the past two years have begun to abandon the Micro USB interface and choose to use it.  The Type-C interface has been introduced, so why are mobile phones now suddenly switching to the Type-C interface? The advantages of USB Type-C are just a few streets that can throw Micro Usb, and entering the twilight is an inevitable result.

1. Supporting high current and high voltage charging helps to improve the charging speed. It can be said that the Type-C interface is born for fast charging technology. In the future, there will be more and more fast charging technologies for USB Type-C interface.

2. Support bi-directional power supply, using USB Typc-C interface can both charge the device itself or external devices (so we can achieve serial charging, use a USB Typc-C interface cable to connect different devices in series  )

3. Strong expansion ability, USB Type-C can transmit audio and video signals, then it can be expanded into a variety of audio and video output interfaces, such as HDMI, DVI, VGA interfaces (in short, it can be used as HDMI, DVI, VGA interfaces  Use, so as long as you have a USB Type-C interface cable, you do not need to buy some HDMI, DVI, VGA interface cables).
