  • Reasons for the heating of the power plug

    Reasons for the heating of the power plug The power plug in the process of using fever is a common phenomenon, such as the most common mobile phone charger, when your mobile phone when charging, charging time to pull the plug, you will find the plug of the charger is very hot, so what is the reason for the plug in the process of using fever? People say the so-called prevent hair hot hot, in fact, insert the connection so that the production process in the power cord plug in the plug connection to work, to meet the strict, no stack, no twists and turns, no crack, no high surface low, as far as possible the perfect power plug to do. Different punching and punching, through a variety of different sizes, different shapes to operate the mold. To condemnation, what kind of mold with insert what, if inserted to rush to die for other types of correspondence, there will be loose and bare copper, so we must correspond to the production. As a kind of South Africa power plug, the terminal is relatively large, we need a thicker wire to fix, but if the customer requirements of the wire diameter is relatively small, how to deal with that? Can increase the copper stripping length, and then folded copper, in order to increase the crude copper wire, so that it can be firmly won't live terminal, loose, also the next production process. For example, the British assembly plug in the work, we must pay attention to the first part of the copper wire package, and then the steps of assembly. In the assembly process, should pay attention to the power line plug to plug in length, should also pay attention to tightening screws, then plug loose on the lower cover will move. All in all, find the cause of the plug heating, if not the reason for the current overload, that is the reason for the plug itself. [View Details]
  • Standard qiaopu power cord is what constitutes

    Standard qiaopu power cord is what constitutes Whether it is for family life or work environment, qiaopu power cord can be said of us in everyday life and work will encounter a daily necessities. For the kinds of common everyday items provides a lot of convenience for my production life, but also allows us to make better use of electricity. However, when it comes to the internal structure of qiaopu power lines, we do not necessarily know. In fact, every one standard qiaopu power cord, mainly constituted by three parts. These three main components of the protective cover, respectively, the inner conductor and the outer protective sleeve. The three main components of a qualified power cord. And each part plays a different role. First, the outer protective sleeve It actually plays the role of protecting power lines, so the outer protective sleeve has a high heat resistance, low temperature, can interfere with natural light and against the life of very higher characteristics. Second, the inner sheath It is actually an insulating jacket for cable wrap is there between the shield wire core layer of material, usually made ​​from PVC and other materials of. We can say that it is a part of an integral part of the power lines. Without it, we can not guarantee the safety of the power line is energized. This is why the wires are not the reason for the leakage. In general, the inner protective sleeve are insulated jacket, because between the outer jacket and insert the conductor, so the material is also very soft. Third, the conductor portion of the power cord qiaopu Are generally made ​​of metal wires of copper or aluminum and other materials to act. But the most common is the use of copper acts as a conductor. And the quality of the relationship between the density of the size of the copper wire with power lines are very close, we can say, a good qiaopu power cord, the number of its copper Flexibility must be up to standard.
