From the use point of view, Phoenix terminals should achieve the following functions: the contact part must be connected, and the contact is reliable. The place where the insulation should not be conducted must be reliably insulated. There are three kinds of common fatal faults of terminals

1.固定不好

1. Poor fixation

菲尼克斯端子固定不好，輕者影響接觸可靠造成瞬間斷電，嚴重的就是產品解體。由于設計不可靠，選材錯誤，成型工藝選擇不當，熱處理，模具，裝配，熔接等工藝質量差，裝配不到位等都會造成固定不好。

Phoenix terminal is not fixed well, light impact contact reliable, resulting in instant power failure, serious is product disintegration. Due to unreliable design, wrong material selection, improper molding process selection, poor quality of heat treatment, mold, assembly, welding and other processes, poor assembly will cause poor fixation.

2.接觸不好

2. Poor contact

菲尼克斯端子內部的金屬導體是端子的核心零件，它將來自外部電線或電纜的電壓，電流或信號傳遞到與其相配的連接器對應的接觸件上，所以要具備優良的結構。由于接觸件結構設計不合理，材料選用錯誤，熱處理電鍍等表面處理工藝不合理，組裝不當，貯存使用環境惡劣和操作使用不當等操作，都會在接觸件的接觸部位和配合部位造成接觸不好。

The metal conductor inside the Phoenix terminal is the core part of the terminal, which transmits the voltage, current or signal from the external wire or cable to the corresponding contact of its matching connector, so it should have excellent structure. Due to the unreasonable structure design of the contact, wrong material selection, unreasonable surface treatment process such as heat treatment and electroplating, improper assembly, bad storage and use environment, improper operation and use, poor contact will be caused at the contact and matching parts of the contact.

3.絕緣不好

3. Poor insulation

絕緣體的作用是使接觸件保持正確的位置排列，并使接觸件與接觸件之間，接觸件與殼體之間相互絕緣。由于絕緣體表面或內部存在金屬多余物，表面塵埃，吸潮，長霉，絕緣材料老化等原因，都會造成短路，漏電，擊穿，絕緣電阻低等絕緣不好現象。

The function of the insulator is to keep the contacts in the correct position, and to insulate the contacts and the shell from each other. Because there are metal residues on the surface or inside of the insulator, dust on the surface, moisture absorption, mildew, aging of insulating materials and other reasons, it will cause short circuit, leakage, breakdown, low insulation resistance and poor insulation.
