Brand reputation: Choose terminals of well-known brands, these brands usually have high product quality and good after-sales service. You can learn about brands and products by looking at product packaging, manuals and certifications.

Material quality: Choose high quality materials made of terminal, such as brass, copper, etc., these materials have good electrical conductivity and corrosion resistance. At the same time, pay attention to the quality of the material, such as whether there are impurities, whether the texture is uniform.

Electrical performance: The terminal should have good electrical performance, such as contact resistance, insulation resistance and voltage resistance. When selecting, it is necessary to select terminals with low and stable contact resistance, while ensuring that they have good insulation properties and voltage resistance.

Mechanical properties: Terminals should have good mechanical properties, such as strength, toughness and wear resistance. In the selection, to choose a terminal with sufficient mechanical strength to ensure that it can withstand a certain external force and impact.
