Environmental Factors Of Copper Terminal Blocks

copper terminal block is usually faced with many different environmental factors, such as: during transportation and storage, during manufacturing, during installation, maintenance and end-customer use. These environmental factors can be understood as given conditions, which can be subdivided into temperature, humidity, corrosion, pollution, internal and external conditions and human factors. The duration of exposure to the changing conditions of these environmental factors must also be determined.
Reliability is a very important consideration in business decisions. From the perspective of a quality engineer or reliability engineer, reliability should be defined as: "a high probability of continuous performance or zero-failure operation under given conditions" or "a high probability of a specific time interval under given conditions" to perform its intended function normally within a period of time. "
The field of reliability involves the evaluation and optimization of various given factors, usually determined by stakeholders to adopt some standardized or upcoming methods. Some technical terms such as "derating" and "failure rate" are often used in the field of reliability.
The storage environment of high-current terminals is different, ranging from controlled clean, heated or air-conditioned, humid warehouses, offices or factories, to uncontrolled corresponding environments. High temperature, humidity or corrosion can seriously affect the service life of terminals. In these uncontrolled environments, the solderability storage life will be greatly reduced due to the intensification of intermetallic oxidation, corrosion and chemical coordination; the surface and function of metals will be affected by rust, copper rust and other forms of corrosion.; As an insulating material, plastics will also be affected by the deterioration of flexibility, strength and shape. The storage period of terminals can be long or short, ranging from a few months to a few years, as short as a few days or weeks. Some require We need to make long-term inventory plans for customers, and some will ship immediately after placing an order. The reliability and storage life of terminal blocks will be improved by adopting a first-in-first-out inventory strategy, a traceable date labeling system, appropriate packaging methods, anti-corrosion methods, improved storage conditions, and appropriate terminal materials and designs.
Transportation environmental factors involve problems caused by vibration, collision, etc. during the operation of transportation vehicles and other mechanical equipment, roads, and loading and unloading tools. However, extreme temperatures usually exacerbate the effects of vibration and collision. Terminals are often exposed to salt spray from seawater. Transportation time is usually predictable. Land and air transportation usually take a few days, while sea transportation takes a month or several months. If the terminals and packaging materials are to remain intact during transportation, they must be able to resist decomposition, deformation, corrosion, and extrusion. The following measures are usually taken to improve the reliability of transportation and ensure that the goods arrive at their destination smoothly.
