The industry's cold winter The global automotive industry's decline has been a consensus. Almost all data from statistical agencies show that 2019 is a car, and the beginning of 2020 can be described as a freezing period, and upstream automotive connectors have also been "frozen"! In 2020, due to the impact of the epidemic, many car companies stopped working and stopped production. The three major automakers in Detroit, Ford, General Motors, and Chrysler have announced the closure of some factories to prevent the spread of the new crown epidemic. The decision of the three giants has also quickly affected other automakers. As of now, more than 150 auto factories worldwide have been pressed. "Pause button". The shutdown of global auto companies has not only depressed the auto industry, but also brought a heavy blow to many auto parts companies. China's auto parts are overwhelmed. It is reported that China's auto parts have contributed 80% of the

The assembly process of electronic wire harness products is very particular and cannot be carried out blindly. This is because any small defect in the production and assembly process will lead to the overall failure of the product and eventually an accident. Although the major manufacturers are well aware of the hazards, they will still make some mistakes during production and assembly in the actual production process.  Konnra wire harness  engineers summarized them, which are roughly reflected in six aspects. 1. Prepare the wires In this part of preparing the wire, the manufacturer must execute it carefully and precisely, because it determines the overall efficiency and performance of the component. Many manufacturers of electronic wiring harnesses choose the wrong wire after the first stage of the error, and these wires are cut and stripped at the end. 2. Do not follow the assembly drawing Failure to follow the assembly drawings can cause many problems when connecting the wi

I believe everyone is well aware that in a new field such as new energy vehicles, high-voltage connectors are important devices, mainly composed of contacts, insulators, housings and accessories. As the operating voltage range of new energy vehicles is increased from 12V to 400V in traditional vehicles, higher requirements are placed on the quality and accuracy of connectors, which are used in vehicle and charging facilities. New energy vehicle connector manufacturers are distributed globally, most of which are Japanese companies, including Sumitomo, Nissan, Yazaki, Toyota and so on. The strongest domestic companies are Basba and China Southern Power Grid. Domestic connector factories such as AVIC Optoelectronics, Yonggui Electric, Guangdong  Konnra , etc., which have been supplied in batches, have gradually grown up. As far as the global connector market is concerned, the market is highly concentrated and basically occupied by the United States, Japan and other countries. Among the

The following  Konnra connecto r engineer will give you a detailed introduction to the characteristics of flexible FPC cable. Generally speaking, when designing a general FPC flat cable product, you need to consider factors such as functional cost, reliability, construction efficiency, and space application. Good design can effectively reduce costs, improve functions and save space, so these should be considered in the design. For functional considerations such as circuit-type cable design, it is assumed that replacing it with an FPC cable can reduce the weight by 50%. Using FPC to design electronic

If you want to classify the connector, you will find that it has many different categories, and today Konnra connector engineer, would like to introduce one of these different categories-flat cable connectors. I do n’t know how much you know about flat cable connectors. Here, Konnra Connectors believes that people who are often engaged in procurement-related work, it is necessary to know flat cable connectors. Konnra connector  engineers point out that flat cable connectors allow compact electrical conductors and piping designs to encapsulate power signals, video data and pneumatic piping in a flat profile. By eliminating the multi-layer shielding and sheathing fillers used in round cables, space and weight are reduced, and the service life is extremely long. Because it adopts a flat and compact design, it is more flexible than other round cables, and it is used in intelligent robots, drag orders, and automatic processing equipment. They are also suitable for military, aerospace,

With the outbreak of the global new crown epidemic and warnings from experts, if the epidemic does not end at the end of June, then the shortage of ventilator will be the same as the current shortage of masks, becoming a veritable "luxury product". According to President Trump ’ s speech, we can know to what extent the current ventilator is in short supply in the United States. His original message was: I have informed GM and Ford to step up into ventilator production and must act immediately. Tesla CEO, Elon Musk also released news via social media that Tesla is always ready to provide ventilators for needed students. Today, the United States also ordered 2,000 ventilators through Philips. From this we can see the current situation of the shortage of ventilator from the United States. What does a ventilator do? Through the early communication with the ventilator manufacturer, we can get some information about the ventilator. A ventilator is a patient who maintains the b
