Do you understand the safety of these wire connectors?

Wire connectors are an accessory that has developed rapidly in recent years. With the globalization of the market, AI technology was born, and 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 achieved unprecedented development, and this market is expanding. As the country with the largest consumption of wire harness cable, China's market potential is naturally huge.

The application of wire connectors is very extensive. For example, equipment and tools commonly used in life, electric water heaters, as well as children's toys, artificial intelligence and other products. Not only cables, but also in many engineering equipment, there are such wire connectors that can be replaced at any time to increase the service life. In the future development, the wire connector is a very important connection device, which greatly facilitates the performance of the device and realizes multi-function. From a global perspective, the share of the company cannot be ignored. In the case of so many applications, should we pay attention to the security risks that are also widely used?

The cause of accidents at the joint
The main cause of an accident is a fire caused by a short circuit, a fever, or an electric spark.
It should be noted that wires and wires, wires and switches, wires and wiring posts, wires and shelters of the electric carrier are peeled off at this point of the joint, resulting in an accident in which the two wires directly collide.

Fever due to excessive contact resistance
In the physical process of the connection head conduction, when the contact area is smaller than the conductor area, the joint heat is likely to be too high and the heat is generated, thereby causing the surrounding combustibles to be incinerated and becoming a fire accident.
Then, what are the reasons for the excessive contact resistance of the connector?

Poor quality of the product:

(1) If the connecting wire is not spliced according to strict regulations, the connection of the connector will not be firm and easy to loose, resulting in sparks and serious fire accidents.

(2) The wires and switches and the electrical appliances are connected through the wire column. Due to the construction sloppy rate, no gasket is added to the terminal, and the nut is not tightened. This will also increase the contact resistance, causing the conductor to melt and the molten beads to fall into flammability. On the item, it causes a fire accident.

(3) Copper wire and aluminum wire are not connected according to the prescribed implementation methods, which poses a safety hazard.

(4) The core of the wire is not twisted, and some of the filaments (core) are turned out. After each collision, a short circuit is formed, and a short circuit occurs after power-on, causing a fire accident.

(5) The phase line connectors are not staggered, the wire joints are broken, and the joints are short-circuited between each other, causing electric sparks, which may cause fire accidents. The long-term open joint is loose and the conductor joint is oxidized.

Measures to prevent accidents at the joint: To minimize the joint of the wire.
