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 mobile devices wi

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,

Interface protection design requirements for USB3.0 connectors

图片
  The protection design of the USB3.0 connector interface has very important significance, so the interface protection design of USB3.0 cannot be sloppy, so what are the interface protection requirements of the   USB3.0 connector ? Let’s read this together. Article, after reading it, you will know the interface protection design requirements of the USB3.0 connector. The high-speed data transmission performance of the USB connector has gradually become a necessary function, and the Universal Serial Bus (USB) interface is an example of the protocol, which is mainly to enhance its data transmission function, while increasing the speed and power, and the new version of USB3 The .0 connector also increases the performance of simultaneous two-way data transmission. The following Konnra connector engineers will come to you to learn about the interface protection design requirements of the USB3.0 connector. The interface protection requirements of the USB3.0 connector cover the threat of fault

The performance and role of connectors in automotive systems

图片
  Whether in traditional cars or new energy cars, automotive electrical connectors are valued by engineers. Because it plays an indispensable role in the normal driving of a car. Let’s talk about the role and performance of automotive electrical connectors today. Generally speaking, in order to ensure safer driving of the car, the choice of car connector must be reliable. How to determine this reliability, that is to ensure that the  electrical connector  in the process of use, the performance of the sealing and spark prevention is stable. Moreover, when the electrical connector is working, it must have temperature control performance and display shielding performance. Regarding the sealing performance of automotive electrical connectors, it is not only aimed at waterproof sealing performance. The international standard specification for closedness of automotive electrical connectors is IP67, which is also the highest specification for closedness in the industry. According to the diffe

Common sense and maintenance methods of waterproof connectors

图片
  Do you know the little knowledge about waterproof connectors? Today,   Konnra connector   engineers will give you a brief description. As the name suggests, the waterproof connector is a connector device with waterproof performance. The products are widely used in LED lamps, driving power supplies, induction sanitary ware, furniture, urban outdoor lighting engineering, machinery, environmental protection, automobiles, construction, ships and other industries. 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. High-quality

Selection factors of display connector

图片
  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 best to

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 calculating, w
