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 voltage,

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 need

In the following, you will be presented with a set of questions and answers about the "What protocol is going on in the BNC interface video output" and the  Konnra Electronics  engineers' Q&A record, so that you can easily understand what protocol is going on in the video output of the BNC interface in the interaction. related question. The core of the problem: What protocol is going inside the BNC interface video output? Problem Description: For example, this bnc interface video output device, BNC is the signal of the H.264 protocol, it is necessary to configure the photoelectric conversion equipment between it and the camera, how to configure it? What kind of docking can it be? Answer: The BNC interface input and output is commonly referred to as the Q9 header, which is used to transmit baseband video signals. The single BNC port of the monitoring device transmits the analog composite signal. The video recorder saves the video file of the analog video signal into

In this installment,  Konnra Electronics  engineers will tell you about the causes of poor crimping of the electronic harness and its consequences. I hope that after reading the user's friends, I can remember these problems and consequences, and try to avoid these areas in practice. 1. Excessive crimping of the skin Bad cause: The crimping gesture is incorrect or the baffle is improperly adjusted, causing the crimping part of the core wire to press into the outer skin, resulting in excessive poor crimping of the outer skin. Consequences: directly affect the crimping of the conductor, causing the current to flow improperly or directly open the circuit. ​ 2. Insufficient crimping of the skin Bad cause: The crimping gesture is incorrect or the crimping speed is too fast, resulting in poor crimping. Consequences: Because the crimping of the conductor and the insulation are insufficient, the tension of the terminal is insufficient, and it is easy to break during the use of the

Customers who frequently purchase connectors have certain concerns about the quality of their products. Before they purchase products, they will conduct various comparisons and find reliable manufacturers to ensure product quality. stable. In addition, before the acceptance of the product, we must also do the testing and testing of the electronic connector, then how to test the electronic connector to know whether it is stable or not,  Konnra Electronics  engineers believe that the five major tests are essential, as follows: 1. Is it safe to work and verify that the voltage test is due to switching, surges and other similar phenomena: the purpose is to verify the ability of the electronic connector to cause transient overvoltages at rated operating voltages. 2. Insulation resistance: The purpose is to establish a method for determining the electrical resistance of an electronic connector and the resistance of each seal under the action of a direct current voltage that causes leakag

Among the types of connectors, there is a product called D-SUB high-current connector, which has many characteristics and has a large demand in the market, if you are a D-sub high-current connector If the product is not familiar, please come and read this article. I believe that after reading it, you will have a deeper understanding of the D-sub high current connector. The times are always moving forward, people have made new changes to the volume requirements of electronic products, and miniaturized products have gradually become more popular selection criteria, so electronic products have higher for miniaturized connectors. Demand. At present, the electronic industry mainly needs miniaturized connectors, but the more precise connectors have limited current when connected, or the current demand for some electronic products cannot be met. In order to meet the development of different industries, some industries produce electronic products that may require connectors of high current

What is your knowledge of board to board connectors? The basic concept of board to board connectors is to connect different boards together. There are many different types, each with its own characteristics, below Konnra Electronics Engineers will introduce you to the board to board connector classification and features. I hope that through our explanation, you can better familiarize yourself with the  board to board connectors . First, pin header / pin Pin headers and mothers, also known as row plugs, are the cheapest and most common connections. Application scenarios: low-end, large-sized smart devices, development boards, debug boards, etc. Advantages: cheap, convenient, hard connection is very stable, strong overcurrent capability, convenient wire bonding and testing. Disadvantages: large size, difficult to bend, large spacing, it is difficult to make hundreds of pin connections (too big). Second, high-end board to board plug More dense than pin headers, used in compact products

There are many  manufacturers of USB type-c connector  data lines on the market, so users can compare the product advantages of each manufacturer when purchasing, so that they can purchase high-quality typc-c connector data cable products. In the following, Konnra Electronics engineers will focus on the five advantages of the USB Type-C connector data cable. Let's take a look at it. The first point: ultra-thin A thinner body requires a thinner port, which is one of the reasons why USB-C was born. The USB type-c port is 0.83 cm long and 0.26 cm wide. Old-fashioned USB ports are 1.4 cm long and 0.65 cm wide, which are outdated. This also means that the end of the USB-C data cable will be one-third the size of a standard USB-A data cable plug. The second point: no matter the positive and negative The interface of the USB Type-C connector is the same as Apple's Lightning interface. The front and back sides of the USB Type-C connector are the same. That is to say, no matter how y
