People's living standards have been constantly improving, and the economic level has improved, so that more people have the money to buy cars. When you buy a car, have you ever thought about the connectors used in these car parts? The connector products used in automobiles are mostly high-speed connectors. When developing high-frequency vehicle connection systems, the design issues of accuracy, mechanical strength and overall applicability when used in harsh environments are first considered. If you want to achieve symmetrical high-frequency electrical signals through the cable and interface for interference-free data communication, the following five characteristics are very important. 1. Constant impedance on the transmission line; 2. The dielectric loss of the insulating material is small; 3. The connector is connected by a good low resistance terminal; 4. Paired signal wires are regularly stranded; 5. Shield part of the repeated coverage. The in-vehicle signal is transmitted...

In recent years, the country has attached great importance to environmental protection issues, including the automotive industry, and is gradually leading to green environmental protection, which is followed by the prosperity of the new energy vehicle market. The development of the new energy vehicle market means that this market needs more new energy connectors. So, what are the four directions for the future development of new energy connectors? In the following,  Konnra Electronics  engineers will focus on introducing you. Knowledge of the future direction of new energy connectors. The future development direction of new energy connectors can be explained in terms of security, green, diversification and modularization. The details are as follows: Security: New energy automotive connectors are subject to higher currents and voltages, and the connectors are subjected to harsh environments such as high-intensity vibration, high temperature, water mist and dust during operat...

There are a variety of welding methods for FPC connectors, and these welding methods are now detailed by Konnra Electronics engineers. The  FPC connector  is used for the connection of the LCD display to the drive circuit (PCB) and is currently based on a 0.5mm pitch product. The 0.3mm pitch product has also been used in large quantities. With the recent trend of LCD drivers being integrated into LCD devices, the number of pins of FPCs has been correspondingly reduced, and related products have appeared on the market. In the longer term, FPC connectors will be expected to be integrated with other mobile phone components on the frame of mobile phones or their LCD modules. Products are mainly used in various digital communication products, portable electronic products, computer peripherals, measuring instruments, automotive electronics and other fields, such as mobile phones, digital cameras, notebook computers, MID, MP3\4\5, handheld game consoles, audio systems, etc. . FPC con...

Among the connecting lines, the terminal line is one of the major categories. It is often used to process internal wiring of various electrical appliances and home appliances, making the connection easier, and the volume of electronic products is greatly reduced, and the cost of production is also reduced. Production efficiency has been improved. However, the premise of these benefits is that the production process is strictly controlled and no bad conditions can occur. In general, there are three main types of defective terminal wires, namely poor contact, poor insulation, and poor fixing. The following three cases are introduced by the  wire harness manufacturer Konnra Electronics . First, the terminal line is in poor contact The contacts of the terminal wires must have an excellent structure, stable and reliable contact retention and good electrical conductivity. Because the metal conductor inside the terminal wire is the core component of the terminal, it transfers the volta...

A netizen recently sent him a "tragic" on the Internet. For the sake of convenience, it has been using VIVO's original charging cable and charging head to charge all Type-C charging ports. This has been used for a year or two. What is the problem. I know that this netizen has recently started a full-format Bluetooth decoding HiFi music player. Because it is also a Type-C interface, this netizen has also charged the music player according to the "international convention". Have fun. After about an hour, the netizen estimated that it was already fully charged, and he was ready to unplug the charging line, but it was a problem at this time. When the netizen's mobile phone touched the music player, the instant condition reflexed the finger back. The music player was hot and hot at this time. After the user unplugged the charger, he tried it again with his finger and found the music. The temperature of the player is about seventy degrees, just like it is going...

Talking about the FPC connector, I think you will not be unfamiliar, because in many fields, the use of FPC connectors will be involved. Then you know, what are the packaging methods of the FPC connector in the manufacturing process? Let the electric bee preferred electronic engineer give you a detailed description of the packaging method of the  FPC connector . Konnra Electronics engineers pointed out that in the production process of small pitch FPC, it is necessary to package to protect the coplanarity of the terminals and the positive position of the terminal arrangement, so as to reduce the quality of the FPC connector products during packaging and transportation. problem. Therefore, two types of packaging are mainly used in packaging, one is a PVC tube package, and the other is a carrier tape package. The details are as follows: First, PVC pipe packaging Among them, the PVC tube package has poor protection performance for the small pitch FPC connector, and the SMT process ...
