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

Electronic connector is a more rapid development of a component in recent years, with electronic and electrical products become indispensable things in life, each widely used in this component, so its market demand is particularly large. It has many application scenarios, we should pay attention to what safety hazards when using this component? Today we mainly to talk about two points during the use of safety hazards.
1, the connection is prone to accidents
　　The main reason for the accident is that the electronic connector in the connection of short circuit, high temperature or electric sparks and cause accidents.
　　During the use of the need to pay attention to is: in several important connections, such as wires and wires, wires and power carriers such as the head of the junction pile parts of the insulation layer is stripped off between the two ends of the line resulting in the formation of accidents between the two ends of the line touching the formation of accidents.
2, because the contact resistance is too large and cause accidents
　　Electronic connector conductive physical process, if the contact area than the conductor area to the small, it is easy to lead to the connector using the process temperature is too high, resulting in excessive contact resistance, when the temperature is very high, it is easy to cause a fire.
Brewing connector contact resistance is too large reasons can be subdivided into the following points:
1, the electronic connector itself is of poor quality.
2, poor contact at the connection, or loose connection after long-term use.
3, oxidation of the connection.
4, the connection has dust, particle pollution.
　　Electronic connectors in today's application is very wide, such as we live in the electric water heater, elevator, mechanical equipment, intelligent electronic products will use it. In order to use the safety, we need to pay attention to the safety of its use, try to avoid the use of security risks.
