4. Materials don't match
Using mismatched wires and terminals can also result in over-crimping. Make sure to use wires and terminals of the correct specifications and follow the recommendations of the crimping tool.
Material mismatch is a potential problem in electrical connections, it can lead to over-crimping or other safety issues, in electrical connections, the use of mismatched wires and terminals can lead to over-crimping, this is because the size and shape of the wires and terminals do not fit, do not fit well. Overcrimping can cause an increase in temperature at the electrical connection point, which can damage insulation and lead to safety issues such as interruption or fire.
Therefore, the correct fittings that match the size and shape of the wires and terminals should always be used during electrical connections. If you are not sure which accessories to use, please consult a professional electrical engineer or professional with relevant qualifications, at the same time, should follow the correct electrical connection process, including the correct wire stripping, the correct terminal circumference and the correct electrical insulation, etc., to ensure that the electrical connection is safe and reliable.
5. The surface of the terminal before crimping is not clean, which affects the contact quality
If the surface of the terminal before crimping is not clean, the contact quality of the connection may be affected. Before crimping, use a cleaning tool, such as a clean cloth or detergent, to clean the dirt, grease, and dust on the surface of the front terminal. Ensure that the surface of the front terminal is clean and thorough. This ensures good contact quality and reduces the occurrence of connection failures and defects. During the crimping operation, the operator should maintain a clean working environment and regularly replace the cleaning tools to ensure the consistency and reliability of cleanliness.
6. The surface of the terminal is oxidized or corroded, which affects the contact quality
The oxidation layer or corrosion on the surface of the terminal will affect the contact quality. When there is an oxide layer or corrosion on the surface of the terminals, they increase the resistance and reduce the flow performance of the current. This can cause the resistance at the connection to become high, which can generate heat energy, damage the circuit or equipment, and may even cause a fire or explosion.
Therefore, when installing or using electronic equipment, it is necessary to ensure that the terminal surface is clean, free of oxidation layer and corrosion. Oxidation layers and corrosion can be removed by cleaning the terminal surface, such as cleaning with alcohol, an acidic solution, or a grinding appliance. In addition, the use of anti-oxidation treatment terminals, joints and wires can also reduce the occurrence of oxidation layers and corrosion.
7. The terminal size does not meet the requirements, resulting in improper crimping
Improper terminal size may result in a weak crimp, because if the size of the terminal is too small, a sufficient contact area may not be formed during crimp, resulting in easy loosening or disconnection of the connection point. On the contrary, if the size of the terminal is too large, it may be too difficult to achieve a sufficient degree of tightness when crimping, and it will also cause the connection point to loosen or disconnect easily.
Therefore, in order to ensure a good connection, it is necessary to select terminals that meet the specifications and use the appropriate tools and techniques to properly crimp them. If the terminal size does not meet the requirements, you should consider using a more suitable terminal or seek professional technical support.
8. The crimping tool is damaged or inappropriate, resulting in uneven crimping
Damaged or ill-fitting crimping tools can cause uneven crimping, which can cause the following problems:
Insufficient strength of the connection point: If the crimping tool applies pressure unevenly, the pressure in some areas may not be sufficient to ensure the strength of the connection point.
Lack of stability of the connection point: If the crimping is not uniform, the connection point may become unstable. This may cause the connection points to become loose or fall off during use.
Damage to the wire: Improper crimping tools may damage the wire during crimping. This may cause a short circuit or a break in the wire.
To avoid these problems, it is recommended to use appropriate crimping tools for crimping and ensure that these tools are kept in good working condition. If the crimping tool is damaged, it should be replaced in time. At the same time, before crimping, you should check that the crimping tool is compatible with the wire or connector to be crimped to ensure that the crimping can be applied evenly to all connection points.
