What safety hazards should I be aware of when using electronic connectors?

With the increase of various types of electronic products, electronic products have become indispensable in life. Electronic connectors have also become one of the more rapid development of electronic components in recent years, it can be said that it has a wide range of applications in various, so its market demand is very large, we need to pay attention to what safety hazards when using the product?　　Manufacturers and technicians said that the product needs to pay attention to two safety hazards during use: First, the connection is easy to accidents Many times the reason why accidents occur is because of the connection of a short circuit, high temperature or electric sparks.　　Therefore, in the use of several connection parts need to pay attention to, such as wires and wires, wires and electrical carriers such as terminals, in the use of time to see whether the insulation layer is flaking, if the insulation layer has flaking phenomenon, easy to cause collision at both ends of the line, resulting in accidents, for such a situation should be handled with care.　　Second, because the contact resistance is too large and cause accidents The product in the conductive physical process, if the contact area is smaller than the area of the conductor, it is likely to lead to the use of the process of temperature is too high, once the temperature is too high, at the same time, it will lead to contact resistance is too large, and in serious cases, it will even cause a fire.　　In addition to the high temperature will lead to excessive contact resistance, the following reasons can also cause excessive contact resistance: 1, the quality of the product itself.　　2, the connection of the place where there is poor contact phenomenon, in the process of long-term use, the connection appears loose.　　3、Oxidization of the connection area occurs.　　4, there is obvious dust and particle pollution in the connection place.　　Very often, because customers buy electronic connectors with poor quality, there are safety hazards during electronic use, so experienced customers will make a variety of comparisons before purchasing, so as to find a reliable partner manufacturer in order to buy products of superior quality and reduce the safety hazards during use.　　A trustworthy manufacturer will test and inspect their own products, testing and inspection of qualified, and then sold to customers, so as a customer, how to test the reliability of product quality and performance stability? The following Suzhou Huicheng Yuan Connector Factory summarized the following five checks, specifically to see what are the contents.　　First, whether it is safe to work: can be determined by the voltage test, the test, you need to understand the product resistance to conversion, surge and other similar phenomena in order to connect the product in the rated operating voltage conditions to produce transient overvoltage capacity.　　Second, insulation resistance: insulation resistance directly affects the quality and performance of the product, mainly to test the product's insulating materials and seals in the DC voltage under the influence of the resistance value, DC voltage back under the product ah the surface of the leakage current.　　Third, the contact resistance: mainly used to measure the resistance of the millivolt voltage drop between the two ends of the contact piece under the specified current conditions.　　Fourth, the electrical continuity between the shell: in the product shell is fixed on the basis of the simulation of the use of the situation to determine the electrical continuity.　　Five, magnetic permeability: mainly used to verify that the magnetic permeability is not in line with the specified value. The above five points to test the quality and performance of electronic connectors to check the project, so that customers can determine the quality of the product, when the purchase of qualified products, want to reduce the use of safety hazards, but also need to pay attention to the safety of its use, and try to avoid the occurrence of safety hazards.
