Low mass connector bad problem lubricant on contacts?

Low quality connectors and other electronic components can cause significant problems for the purchaser, as connectors that are too low in quality will not meet the requirements of the application in terms of either performance or standards, and may cause equipment failure or damage when used. Lubricants can reduce mating forces between connector contacts and contact wear, but lubricants don't just reduce connector wear problems, they also bring a number of other effects to connector contacts.

Low quality connectors have poor mechanical properties.2, Low quality connectors have poor environmental properties.3, Low quality connectors have poor electrical and temperature properties.4, Low quality connectors are designed with materials that do not meet RoHS requirements.5, Low quality connectors are more haphazardly processed and have rough surfaces.6, Automotive connectors Low quality connectors do not have a standardized quality certificate, such as a UL certification.7, Low quality connectors have poor product consistency.8, Low quality connectors lack production and traceability.9, Low quality connectors are not manufactured in the same manner as other automotive connectors. Low quality connectors have poor product consistency.8, Low quality connectors lack production records and traceability. Metal contacts are often used in connectors for demanding applications, such as connectors that require high performance, reliability and high pin count, while high-performance and reliability connectors require low and stable contact resistance, and their high pin count automotive connectors require low and controlled mating force, in which case the contact lubricant must provide corrosion protection for resistance stability and reduce friction to minimize the mating force of the connector. In terms of corrosion, gold-plated or nickel-plated connectors, the source of corrosion is the copper alloy spring material, which is susceptible to a variety of corrosion mechanisms, connector contacts using a lubricant can be in the vicinity of the contact area of the plating and exposed copper alloy in the aperture to provide a protective layer. The tin-plated contact surface of the connector is susceptible to different corrosion mechanisms, namely for micro-motion corrosion factors, micro-motion refers to the small-scale movement that occurs as a result of mechanical (vibration/shock new energy automotive connectors) or thermal (thermal expansion mismatch) driving force, from a few microns to a few micrometers, the corrosion is due to the accumulation of micro-motion movement in the contact interface of the tin oxide abrasive debris, abrasive wear debris accumulation leads to an increase in the contact resistance over time The rate of increase depends on the number of micro-movements that occur. Micro-motion corrosion degradation can result in high resistance in as few as a few thousand cycles. In tin-plated connector applications, the primary purpose of a lubricant is to reduce the potential for micro-motion corrosion, which can be accomplished by providing a protective layer that reduces the likelihood of corrosion and by minimizing the amount of abrasion that occurs during each micro-motion cycle.
