  Whether in traditional cars or new energy cars, automotive electrical connectors are valued by engineers. Because it plays an indispensable role in the normal driving of a car. Let’s talk about the role and performance of automotive electrical connectors today. Generally speaking, in order to ensure safer driving of the car, the choice of car connector must be reliable. How to determine this reliability, that is to ensure that the  electrical connector  in the process of use, the performance of the sealing and spark prevention is stable. Moreover, when the electrical connector is working, it must have temperature control performance and display shielding performance. Regarding the sealing performance of automotive electrical connectors, it is not only aimed at waterproof sealing performance. The international standard specification for closedness of automotive electrical connectors is IP67, which is also the highest specification for closedness in the industry. Accordin...

When we design and manufacture industrial machinery, or consumer equipment, we are faced with a choice, whether to use point-to-point cable "hard connection" to the system, or choose a plug-and-play connector. From a longer-term perspective, of course, the wiring based on connector products is more practical and lower in cost.  Konnra connector  engineers will investigate the reasons behind and introduce you to the fact that connectors are better than hard wiring. Where is it. 1. More time-saving and lower cost General industrial equipment contains a large number of wires between its components and subsystems. When the original equipment manufacturer manufactures the product, it will be assembled at the factory before shipment, then the system is disassembled, disconnected and shipped to the end user, where it is reassembled . If you need to hardwire all cables into the system, then remove and rewire them on site, this will be a very time-consuming task. The pre-assembled con...

Needless to say, everyone already knows that automotive electrical connectors are accessories specifically designed for automotive electrical systems. With the continuous upgrade of the manufacturing industry, the automotive system has also undergone tremendous changes. Modern systems are widely connected and controlled through microprocessors, which has also caused the market to continue to increase the demand for high-quality wiring and electrical connectors. With the increase in product demand, the types of crimping automotive electrical connectors have also diversified.  Konnra connector  engineers will introduce the types of crimping automotive electrical connectors for you. When manufacturing a vehicle, when selecting an automotive electrical connector, the current rating, circuit density, wire size, voltage, configuration, and meshing force of the product must be considered. Due to the different sizes of crimping connectors, which can effectively accommodate the largest...

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 ...

There are a variety of problems encountered in the production of wire harnesses, not only from the product itself, but also from the process flow class. In the process flow, it will involve the problem of terminal machine failure. How can the wire harness manufacturer solve the terminal machine failure? The following  Konnra Electroncis  engineers will answer you when the terminal machine is faulty. What should I do? The first point: When the length of the cutting of the electronic wire is inconsistent, the possible reason is that the wire feeding wheel of the terminal machine is pressed too tightly or too loosely; the solution is to adjust the straightening device so as to be able to perform the straightening function and can be smoothly sent out. , the cutting edge is worn or the knife edge is replaced or a new cutter is replaced. Second point: When the length of the peeling opening is different, the wire feeding wheel may be pressed too tightly or loosely; use the roller...

The electronic wire harness product is a very large category, and there are many other categories under it, and the car wiring harness is one of them. So you know what a car harness is, and the  automotive wire harness manufacturer , Konnra Electronics Engineer, will tear the veil of the car harness for you, so that you no longer wonder what the car harness is. Konnra Electronics engineers pointed out that the automobile wiring harness is an important component for connecting various electrical parts and circuit board equipment of the automobile. The function of transmitting signals in the entire circuit board connection system of the automobile is a carrier for controlling the circuit signal transmission of the automobile itself, and it can be said that there is no There is no circuit connection in the car wiring harness and the car's connection system. With the continuous improvement of the social and economic level, people's requirements for automobiles are getting hig...

The car wiring harness is also known as the "blood vessel" of the car. It is often referred to as the central nervous system of a car. The position of the car harness design in the whole vehicle is very important. Studying the quality control points of the automotive wiring harness manufacturing process is of great significance for improving the vehicle qualification rate and reliability. There are four main processes in the production of automotive wiring harnesses: stripping – crimping – pre-loading – assembly. The production process sets the corresponding standardized operation specifications for different production processes, so that the quality of the wire harness products produced can be effectively guaranteed. (Image from Internet) Stripping process Stripping refers to stripping the insulation on the wire according to the requirements of the work instruction, and the length should meet the requirements. Good stripping requires wire type, wire diameter, thread ...

This article starts with the four basic structures of the automotive connector, introduces the design standard of the automotive connector, analyzes the stability of the automotive connector, analyzes the three failure modes of the automotive connector, and interprets the car connection. The development of the device, and finally for the market demand brought by this development, the corresponding automotive connector application examples are given. (Image from internet) The form and structure of the automotive connector is ever-changing. It is mainly composed of four basic structural components: contact, housing (depending on the type), insulator, and accessories. These four basic structural components enable the automotive connector to act as a bridge for stable operation. The contact piece is the core part of the automotive connector to complete the electrical connection function. The contact pair is generally composed of a male contact and a female contact, and the electrical ...

With the increasing popularity of automobiles, the problem of how to choose the wiring harness and connectors has become the doubt of many automakers and buyers. Konnra Electronics  is here to help you choose the wiring harness and connectors for your car. Automotive low voltage wire The 600V withstand voltage is a low-voltage electric wire in the electrical classification, and it has become a low-voltage electric wire for automobiles because it is attached to the characteristics of a car in the automobile field. The wires are also classified into a heat resistant type and a thin type depending on the material thickness of the insulator. A) Construction of the conductor B) Insulator In order to prevent the burning of electric wires due to heat generation, a flame retardant is added in advance in the insulator. The flame retardant is also a plastic material, which acts to soften the insulator. At high temperatures, the flame retardant will be released and the insulator will...
