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

  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

  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

  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

  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

  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 mechani
