Talking about the function, classification and working principle of OTG data line

图片
  What is the OTG line? OTG is mainly applied to the connection between various devices or mobile devices for data exchange. The development of USB technology enables computers and peripheral mobile devices to transmit various data through simple USB connections. This will lead to a situation, once the mobile phone or tablet does not have a computer, we cannot manage the data of mobile devices such as mobile phones, which brings inconvenience to users. As mobile devices such as mobile phones become more and more like computers, can we imagine that we can use mobile phones as computers? Can a U disk, USB network card, etc. be connected to the phone? The answer is yes, the OTG function is to realize that the mobile phone can be connected with USB devices such as U disk, but the mobile phone has a tiny   USB   interface, which cannot meet the needs of USB ports such as U disk. So far, the OTG data cable came into being. The role of OTG is to realize data transfer between mob...

Who will become the mainstream of the HDMI and DP interfaces used on the display in the future

图片
  PS5, Xbox series S consoles and other next-generation devices have been released one after another. The HDMI and DP interfaces currently used on displays will become mainstream in the future? Let me give you a brief introduction to the current interface status. At present, the interface of the display will be equipped with HDMI and DP interfaces, while the VGA interface and DVI interface can only be seen on some low-end displays, and it is basically certain to exit the stage of history. At present, the HDMI interface in the mainstream interface of the display is a left-right symmetrical trapezoid. TVs, computers, and projectors all support it, and it is currently a more common connection port. Compared with the HDMI interface, the DP interface is much more "specific". It was developed for the computer field from the beginning, so there is almost no DP interface for electronic devices other than monitors and graphics cards. In addition to the different interface use ranges, ...

The waterproof joint adopts nylon material with good sealing performance, safety and reliability. The reason why nylon material is used is that nylon pipe fittings are suitable for long-term water contact, non-corrosive, non-rusting, non-toxic, adaptable to temperatures of -40° to 135°, and have a service life of more than 50 years. It has strong impact resistance, good toughness, high compressive strength, good leakage resistance, energy saving, green environmental protection, no human body, no secondary pollution...

Selection factors of display connector

  As the name implies, the display connector is the connector used in the display. Generally, it refers to the connector used on the display wire harness and the board-to-board connector used on the PCB. There are still many companies in the market that do this. Type of connector, but because of this, the quality needs to be carefully distinguished. There are still relatively few safe and reliable high-quality connectors in the market. Here are five ways to tell you how to choose the   display connector . Five considerations for choosing a display connector: 1. Pay attention to the actual situation, not just look at the standard, but go beyond the standard. Because of the rapid development of the display industry and great changes, we can clearly see that it took only a short time from the first color TV to today’s 4K and 8K TVs, and the mechanical and environmental performance of the connectors are constantly improving. Claim. Therefore, when considering quality issues, it is...

Calculation method of wire diameter of automobile wiring harness

图片
  When using the CATIA module for wire harness data production, the wire harness segment diameter is written into the software as an important parameter. All subsequent clearance checks and motion analysis are based on this value. Therefore, if there is a big difference from the actual situation, it will inevitably lead to the original requirement of meeting the safety gap, and it will be found to have interfered when the vehicle is actually installed, or even cannot be assembled. Konnra wiring harness  engineers provide you with a theoretical calculation method (wire harness standard algorithm) for estimating the outer diameter of automotive wiring harnesses. A wire harness segment is a collection that binds all wires together with tape or other wrapping. Taking into account that the tape is only wound on the wire harness, and the wrapping of casings such as corrugated pipes also needs to determine the outer diameter of the wire harness before selection. Therefore, when calcu...

  In our work and life, we cannot do without the video cable. We need to connect the set-top box and the TV when watching TV, connect the host and the display when we work, and connect the laptop and the projector when casting the screen in a meeting. So choosing a good video cable is very important. There are currently four common video interface types: VGA, HDMI, DVI, DP, so what is the difference between these four video cables? How should I choose? 1. DP DisplayPort is a high-definition digital display interface standard, which can be connected to computers and monitors, as well as computers and home theaters. As the successor to DVI, DisplayPort will add support for high-definition audio signal transmission while transmitting video signals, while supporting higher resolution and refresh rates. For data transmission, DisplayPort uses the "micro-packetised" format. At the same time, DisplayPort has a high degree of scalability, and more new content can be added in the futu...

BMA connector

图片
  In many applications, screw-on RF connections can sometimes appear stretched and even unusable: for example, panels, daughter cards or inserts with multiple RF connection points. In these cases, the spacing between the connectors must be set very small, so that the nut cannot be accommodated; or the card/combination sometimes cannot be operated due to the need to be inserted into the slot. For these reasons, people have developed push-in connectors, also known as blind-mate connectors. The common blind-mate connector in military, aerospace, satellite communications and radar fields is the Blind-mate A/BMA (Blind-mate A/BMA) connector developed in the 1980s. In the initial period, the registered trademark used by BMA connectors was OSP, so it is often called OSP connector. The advantage of the BMA connector is that even if there is a slight degree of misalignment, mating can be easily achieved by pressing the plug into the socket with sufficient pressure, and then the internal mec...

  Recently, many users have asked the question "what indicators should be considered for a good quality connector". For connector purchasers, their biggest goal should be to purchase products with reliable quality and meeting requirements. However, the production of a connector is so complicated, how should a purchaser know whether the product quality is good or not? The following is analyzed by the engineers of   Konnra connector : When choosing a high-quality connector, the indicators to be considered include 14 aspects, as follows: 1. The current carrying capacity index of the connector Generally, the current carrying capacity of the connector power signal should be designed with a derating, while paying attention to the insulation withstand voltage between the pins. 2, the impedance matching index of the connector Some equipment signals have impedance requirements, especially radio frequency signals, which have stricter impedance matching requirements. When impedance does...
