Konnra Electronics CO., LTD.

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...

Have you heard of the fretting corrosion phenomenon in electronic connector interconnection? Can you know the impact of fretting corrosion in electronic connector interconnection? In this article, Konnra connector engineers will focus on introducing this issue to you. Hope that after our introduction, you have a deeper understanding of electronic connector products. Konnra connector engineers pointed out that the fretting movement is usually less than 0.005 inches (0.127 mm). After the appropriate conditions are met, almost all oxidized materials are in danger of fretting corrosion. When the connector is interconnected with the device, it is prone to fretting corrosion, which leads to a variety of problems, and the performance will also be affected. So in the end, the effect of fretting corrosion in the interconnection of electronic connectors is Which, to summarize, can be summarized into two points, as follows: 1. Fretting corrosion occurs in the interconnection of electronic connect...

In our factory, tens of thousands of connector products are produced every day, including many gold-plated connectors. When it comes to gold-plated connectors, we have to talk about the benefits of the nickel backplane used by gold-plated connectors. I don’t know how much you know about the benefits of using nickel backplanes for these gold-plated connectors, but  Konnra connectors  engineer just wants to say that the excellent function that these nickel floors bring to the gold-plated connectors is really too powerful. Let's take a look at how powerful the gold-plated connectors after using the nickel base plate. The reason why gold-plated connector products use nickel baseplates in a large amount. The key to this is the performance of nickel. It makes the connector products more reliable, and also allows gold-plated connectors to have the following four functions: 1. Leveling layer The nickel base plate can be used as a leveling agent, which can produce a surface roughness w...

The 2020 Shanghai Electronics Fair in Munich, known as the wind vane of the Chinese electronics industry, will be held at the National Convention and Exhibition Center (Shanghai) on July 3-5.

Dare to move forward and be courageous, this is the choice made by Mu Zhan! We also call on and look forward to your participation in the "2020 China Electronics Industry Renaissance Plan" with us to build a temperature, value, and meaningful...

Many users have been confused about the "chemical gold", "plated gold" and "flash gold" on the PCB board, and some people are always unable to distinguish between "hard gold" and "soft gold" Many people often ask, how thick should the connector be gold-plated?  Konnra connector  engineers will focus on introducing you to the differences between PCB and connector commonly used gold-plating process and their characteristics, so that everyone will no longer be confused in this regard. Gold plating process In the PCB and connector industry, the plating process related to us. It is mainly divided into two categories: electrolytic plating (hereinafter referred to as electroplating) and chemical plating. Electroplating: Electroplating refers to the process of performing an electrolytic reaction in a solution by the action of external current to deposit a uniform and dense metal or alloy on the surface of the substance to be coated. The electro...

Regarding the 3D printer board, the Konnra connector provides board end designers with several connectors and harness solutions. This motherboard has been upgraded with the WIFI module added in the previous version, as shown below: The connectors used in the motherboard are:  KR1271 pin headers ,  KR2013 box header connectors ,  KR3961 connectors  and  Micro USB connector .

Konnra connectors participated in a joint R & D design project of PCB boards. After the joint efforts of the project company and our company, the products are as follows: The board end shares our four types of connectors, namely:  Type-C ,  Type-B 3.0 ,  HDMI  and  KR3000 dual-row DIP series connectors , and our company also provides related supporting harnesses. Konnra Solution is committed to being a leading connector solution provider.

In our daily life, the frequency of use of male power connector products is very high, so it is also an important matter to do the daily maintenance work of male power connector products. When it comes to the maintenance of the male connector of the power connector, it is indispensable to the cleaning of the male connector of the power connector, then do you know what the correct cleaning process of the male connector of the power connector is? The  Konnra connector  engineer will come to you for details. Introduce the knowledge about cleaning the power connector. The cleaning process of the male connector of the power connector can be roughly divided into three steps, as follows: Step 1: Wipe the power connector with a clean cloth until there is no dirt or debris. Then separate the connector to expose the female socket and the male plug, and observe the status of the male pin. If green or white powder appears on the pin, it indicates corrosion. If the metal looks rusty and cr...

Konnra not only a manufacturer of connectors and wire harnesses.She is a connector solution provider also.

Among the components, the design of the product often has a strong correlation with its performance. A good design can not only improve the aesthetics of the product, but also extend the service life of the product. Then how much do you know about the design knowledge of single-row, Konnra connectors ' engineer will give you a detailed introduction to the advanced nature of the single-row needle design. The development of single-row needles should be miniaturized. Since many products have to face smaller and lighter developments, there are certain requirements for spacing, appearance, and height, which will make the product requirements more precise The best choice for the board is small pitch 0.6mm and 0.8mm, high density, high speed transmission, high frequency direction development. Miniaturization means that the center spacing of single-row needles is smaller, and high density means the realization of a large number of cores. The function of the single-row pin is to act as a br...
