Description

Lightning terminal, USB interface connector and USB interface slot Technical field

The utility model relates to an electronic product connector interface technology, in particular to a Lightning terminal, a USB interface connector and a USB interface slot.

Background technique

Apple's high-speed multi-function I/O interface is September 12, 2012, the United States San Francisco Fangcao Conference Center Apple released a new Lightning Dock interface, Chinese can be translated as "Lightning" interface. The release of the new interface standard means that Apple's 30-pin Dock interface, which has been in use for nine years, will be officially replaced. The Lightning interface of the prior art has eight pin contacts on both sides, and can be operated normally regardless of the front and back sides. So there is no need to worry about the problem of plugging in. Apple emphasized in the official media that the new interface is not only easier to use, but also more durable, and further pointed out that the new Lightning interface is an "all-digital" and "adaptive function" interface. Among them, the meaning of "adaptive" is that it can transmit the specific signals required by the accessories through the interface according to different accessories; the new Lightning interface also supports video output, and has the same technical effect as the 30pinDock interface. Based on this feature, Apple also introduced the Lightningto HDMI/VGA converter. Further, the Lightning interface in the prior art has a very large advantage in size; it is 80% smaller than the original 30pin Dock interface, meaning that the space reserved on the device for this interface is at least 80% smaller. . In addition, after dropping from 30pin to 8pin, the complexity of the relevant circuit is further reduced. Therefore, the new Lightning interface provides strong structural support for the iPhone 5's thickness compared to the iPhone4S's 20% slimmer.

The Lightning Dock interface in the prior art is more durable than the 30pinDock interface. In addition to the advantages of the front and back plugging, the shape design of the interface itself is also quite knowledgeable. Apple's Lightning Dock interface has eight pins on each side, and the white part separates the pins from each other. The outermost metal actually acts as a grounding function, so strictly speaking, the Lightning interface uses a 9pin pin design. There are a little recesses on each side of the joint. This is mainly for the tight "card" in the slot (there is a spring piece on each of the left and right sides of the slot). When plugged in, the metal part with the grounding function will first enter the slot, avoiding the problem of static electricity caused by the signal pin being connected first. Connect The top of the head is provided with rounded corners, which is convenient for the metal sheets on both sides to be more easily pressed against the spring pieces on both sides of the slot when inserted, thereby achieving the technical effect of smooth insertion. In addition, the rounded corners on the top can further achieve the technical effect of cleaning the 8 signal contacts on the slot end when the Lightning connector is inserted. When designing the slot, it is preferable to provide the contact only on the inner side, thereby achieving the technical effect of lowering the height of the slot.

The Lightning interface in the prior art is excellent, but it is not compatible with existing 30pin interface accessories. Apple will come with a USB to Lightning interface cable on the iPhone 5 and the new iPod, but it does not include the adapter for the new interface and the old interface. Further, similar to the difference between the DVI interface and the HDMI interface, the Lightning interface does not support the audio output of the analog signal, and it is a "pure digital" interface. Therefore, the existing accessory manufacturers have to make a harsh choice of the signal output mode when the accessories are produced. It is necessary to completely adopt the digital signal, or integrate a "digital-to-analog converter (DAC)" in the speaker, which invisibly improves the accessory product. Manufacturing costs. In the prior art, although Apple introduced the Lightning to 30pin adapter, the adapter does not support video output and iPod mode (iPod mode is a special mode, its function is to display the on-screen menu on the iPod directly Go to some of the accessories on your own display.). First of all, the Lightning to 30pin adapter is not compatible with projectors that previously supported the 30pin Dock interface. Secondly, Apple's description of the official product description of the Lightning to 30pin adapter is very implied, only accepting that the adapter is not available. Support for the possibility of some 30pin accessories. In addition, in the prior art, the officially produced Lightning interface of Apple also hides a chip, which can identify and prevent non-Apple officially authorized accessory products from being connected with it, thereby hindering the further development and production of Apple accessory products by domestic SMEs. .

Therefore, it has become necessary to develop a Lightning terminal and a USB interface connector to overcome at least one of the above technical drawbacks.
