Terminals are generally the maximum current 10A, voltage 250V, refers to the electrical plug and socket contact, current flows through the heat, the maximum current 10A finger contact is good, the maximum current through the contacts; voltage 250V insulated maximum working voltage can withstand the wiring board, more than this value may be leakage. For the terminal multiple section level with uniform accessories, such as end plate, separating plate, etc.. Potential distribution by an access terminal central fixed bridge or insert wiring cavity side plug bridge to achieve.

 

Terminals must traverse with electric heater wire terminals of the one one corresponding, avoiding the pressure caused by short circuit accident. Terminal inside a metal conductor is the core part of the terminal voltage, it will come from external wires or cables, contact current or signal to the connector matched on the corresponding. The contact must have good structure, stable and reliable contact force and good conductive properties. Because the contact structure unreasonable design, material selection errors, die is not stable, the processing dimension tolerance, surface roughness, heat treatment, electroplating and other surface treatment process is not reasonable, inappropriate assembly, storage used in harsh environment and improper operations, will be in the contact portions of the contacts and the matched parts caused by poor contact. The three wires are positive, negative and shielding. XLR is called the "balanced terminal" and "the microphone plug", host is composed of three pole plug and cable connection.

 

In accordance with the mark pole plug on NL and symbol grounding wire, must lead with electric heater crimping terminal on the one one corresponding, short-circuit accident caused by avoiding the pressure line. As a quality engineer or reliability engineer's point of view, the reliability is defined as follows, under certain conditions, zero failure continued to perform operation or maximum likelihood, maximum likelihood or something in a given condition, in the certain period can play its due function.

Terminal storage environment is different from the control, clean, heating or air conditioning, wet warehouse, office or factory, the environment can not control. Will seriously affect the service life of the heating terminal, moisture or corrosion condition. Environmental factors relate to transportation due to vibration and impact of transport vehicles and other mechanical devices, pavement, loading and unloading tool produces in the process of operation problems. And temperature extremes are often combined and exacerbate the effects of vibration, collision. In business decisions, the reliability is very important factors to consider.
