The application of electronic wire processing and heat shrink tubing is paramount in the production of charging guns. Accurately cutting the electronic wire to the appropriate length ensures a rational internal layout, preventing excessive length that could cause entanglement or insufficient length that could hinder proper connection. Heat shrink tubing provides insulation protection for the electronic wires and enhances their mechanical strength, safeguarding them from external physical damage.
First, they provide the fundamental assurance of electrical connectivity. EV charging guns rely on electronic wires to transmit electrical energy. Properly cutting the wires to the correct length ensures an efficient internal layout. For instance, in the section connecting the charging gun to the charging station and the vehicle’s charging interface, precise cutting allows the wires to be neatly arranged within the limited space, facilitating assembly and subsequent maintenance.
Second, they ensure the accuracy of signal transmission. Besides transmitting electrical energy, the charging gun also needs to convey control signals. For example, in charging guns equipped with electronic locking mechanisms, signal wires transmit signals through accurately processed electronic wires, ensuring the charging gun can correctly lock and unlock, thereby guaranteeing the safety of the charging process.
1. Use a computer-controlled wire cutting and stripping machine to perform cutting and stripping operations on the electronic wires.
2. Then, organize the cut and stripped wires and send them to the next workstation.
Heat shrink tubing serves two primary functions in the production of electric vehicle (EV) charging guns.First, it provides insulation protection. Heat shrink tubing insulates electronic wires, which is crucial in EV charging that involves high voltage and large currents. If the insulation layer of the electronic wires is damaged, it could lead to electrical leakage, posing a risk of electric shock to users.
Second, it enhances mechanical protection and stability. Heat shrink tubing increases the mechanical strength of electronic wires, shielding them from external physical damage. During the daily use of charging guns, electronic wires may be subjected to bending, pulling, and other external forces. Heat shrink tubing can absorb these forces, reducing the likelihood of damage to the wire conductors. For instance, when users plug and unplug the charging gun, the electronic wires experience some pulling force, and heat shrink tubing can prevent the wires from breaking near the plug.
1. Prepare the appropriate terminals, then use a terminal machine to crimp the corresponding terminals onto each core wire.
2. Finally, wrap the heat shrink tubing around the connection between the terminals and the core wires, and use a Heat shrinkage to shrink it.
This is the first one.
