Terminal storage life can be long or short, long months years, short days, weeks, some need to make long-term inventory plan for customers, while others order production immediately out of storage. Terminal reliability and storage life can be improved by adopting a first-in, first-out inventory strategy, a traceability label system, proper packaging, corrosion prevention, improved storage conditions, and proper terminal material and design.
https://www.bossgoo.com/product-detail/insulated-female-connectors-connector-copper-lugs-61373843.html Terminals are often exposed to a number of 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 changing conditions from these environmental factors must also be defined. Storage, high-current terminal storage environments vary from controlled clean, heated or air-conditioned, damp warehouses, offices or factories to uncontrollable corresponding environments. The service life of the terminal is seriously affected by heat, humidity, or corrosion. In these uncontrolled environments, weldability storage life is greatly reduced by oxidation, corrosion, and increased metallization; The surface and function of metal devices are affected by rust, patina and other forms of corrosion; Plastic as an insulating material can also be affected by deterioration of its flexibility, strength and shape.
Wiring terminals are generally composed of shrapnel, conductive parts and insulating parts (plastic case). When wiring, the screwdriver import plastic shell on the right side of a square hole, upward tilt screwdriver, give a downward pressure shrapnel, shrapnel square hole can be aligned with the conductive wire frame of holes, again from plastic shell hole into the wire, make it into the conductive parts so as to realize the connection of wires and terminals, wire connection, then the terminal plug and fixed on the circuit board supporting the socket connection, Can realize the circuit board to transmit signal function. It should be pointed out that when the socket of the wiring terminal block is connected with the plug, the solder feet (or conductive parts) in the socket can achieve seamless contact with the conductive parts in the plug, so as to ensure good conductive effect. The unwiring process is similar to the wiring process. Press the spring downward with a screwdriver and pull out the conductor directly from the conductive part.
