The consequences of poor electronic wiring harness

图片
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 product, which di…

Five tests take you to avoid the instability of the electronic connector

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 leakage of cu…

D-SUB high current connector knowledge

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 typ…

Board to board connectors classification and advantages and disadvantages

图片
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.
Applicatio…

Five advantages of the type-c connector

图片
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 you inser…
