Wire connector is an accessory that has developed rapidly in recent years. With the globalization of the market, AI technology is born in this industry. Wire connectors are widely used in every country, and the demand is particularly large.

Since the reform and opening up, the domestic wire connector technology has also been an unprecedented development, and the market is expanding. As the largest consumer of wire harness and cable, China's market potential is also huge.

Wire connectors are widely used. For example, life commonly used equipment tools, elevators, electric water heaters, as well as children's toys, artificial intelligence and other products. Not only cables, but also many engineering instruments have this kind of wire connector. With this kind of connector, accessories can be replaced at any time to increase service life. In the future development, wire connector is a very important connecting device, which greatly facilitates the performance of the device and realizes multi-function.

From a global point of view, we can not ignore its share. With so many application scenarios, should we pay attention to the security risks while it is widely used?

Causes of accidents at joints

The main cause of the accident is the fire caused by short circuit, fever or electric spark.

Attention should be paid to the following: the insulation layer of wires and wires, wires and switches, wires and connection pile heads of electric carriers, wires and shielding devices at the connection point is peeled off, resulting in the accident of direct collision between two wires.

Fever due to excessive contact resistance

In the physical process of connector conducting electricity, when the contact area is less than the conductor area, it is easy to cause excessive heat and fever of the connector, which will cause burning of combustible materials around and become a fire accident.

Then, what are the reasons for the excessive contact resistance of the connector?

1. Poor resettlement quality

2. Long term open joint looseness

3. Oxidation occurs at the junction of conductors

4. Dust pollution

5. Measures to prevent accidents at joints

6. Try to reduce the connection of wires as much as possible
