Konnra Electronics CO., LTD.

For most manufacturers, if you want your products to be recognized by customers, in addition to the excellent quality, if they can pass some qualification certifications, then the sales of the products may have unexpected effects.  Konnra connector  engineers will take you to know the relevant knowledge of European Union (EU) RoHS certification. Konnra engineers pointed out that RoHS was promulgated in the European Union (EU) in February 2003. This EU regulation aims to restrict the use of hazardous substances in electrical and electronic equipment (EEE). Among the prohibited substances, perhaps the most widely known is Lead (Pb) too. Later, RoHS certification gradually formed a standard specification in the connector industry. After the products produced by manufacturers conform to these specifications, product sales are bound to be broken. The Restriction of Hazardous Substances Directive (RoHS) and the Registration, Evaluation, Authorization and Restriction of Chemical Subs...

In recent years, my country's 3D printing market as a whole has shown a steady and positive trend. More and more companies have entered the 3D printing field and hope to occupy a place in the entire 3D printing market. In the current domestic market, industrial-grade 3D printers occupy the mainstream, and light curing equipment occupies the largest market share. In terms of brand competition, there are many brands in my country's 3D printing market, but foreign brands occupy a dominant position. Industrial-grade 3D printing equipment dominates 3D printing is mainly divided into two types: desktop and industrial. The desktop level is the initial and introductory stage of 3D printing technology, which can explain the process principle of 3D printing technology intuitively. Industrial-grade 3D printers are mainly divided into two types: rapid prototyping and direct product manufacturing. Desktop-level 3D printers are relatively inexpensive. Printers with plastic as the main materi...

As one of the hot-selling categories among many connectors, the USB connector has always been favored by the market and can be found in many high-end fields.

I believe everyone is well aware that for those connector products that are used in industrial connectors, customers have higher performance requirements, and engineers usually specify sealed connectors. Under our current industry standards, the standard for judging the performance of a sealed connector is mainly based on its IP rating, from IP22 (protection against finger insertion and intermittent dripping) to IP69K (full dust protection and sufficient moisture protection), Products that meet such requirements can basically be recognized by customers. In addition, if we want to consider the product operating environment and operating requirements more thoroughly, what factors should we consider when designating industrial sealed connectors?  Konnra connector  engineers will answer this question for you in detail. The factors we need to pay attention to involve five aspects, and the specific content is as follows: 1. Levels and requirements Grades and requirements cannot be i...

People who often buy connectors, carefully observe the plating indicator on the connector. We will find that the alignment may be small and not very beautiful, but it is this arrangement that is not very beautiful, but it is the most important of any connector. One of the components. However, it is not a difficult thing to make the appearance of the connection better. Some of us can plate the connection, so that it can be a good replacement. So what is the role of electroplating the connector plating?  Konnra connector  engineer will come to you to popularize the effect of electroplating the connector connection plating. Konnra connector engineers pointed out that electroplating is the process of depositing another layer of metal on another metal. Simply put, it is achieved by using a series connection and a liquid solution containing the plating material. What are the benefits of the plating process? Connector conductor plating has many effects. A good connection of the plati...

When  professional connector manufacturers  produce their products, they will produce many types of alternations for the products. This is because, in the current situation, there is no one product that can fit all the applications of single design connector alternation, so Most connector manufacturers will produce connectors to complete specific production tasks. So what is the role of different series connector links? Konnra connector engineers will come to introduce you to the knowledge of different series of connectors. One, contact resistance lead The efficiency needs to be ensured. The design must ensure that the resistance of any circuit is kept at a reduced position. The lower the resistance, the less power is lost during transmission. Each component added to the circuit may increase resistance, especially for connectors. The metal used to make the connection, the plating and the design of the interconnect itself can all help keep the resistance low. However, it is imp...
