Electronic connector products can be applied to connector systems in various industries, and an effective connector system should provide sufficient levels of contact force, maintain airtight connections at the contact interface, and help to replace particles and oxides during the mating cycle. In addition, the relative sliding degree between pairs should usually move the particles to one side to expose the metallurgical contact interface.
The balance between contact force and sliding action may have a significant impact on the reliability and cost of connector systems, while the number of contact interfaces may affect the time and rate of plug related failures. Increasing the number of contacts or using multi sided mating contacts can reduce the risk of failure. Although it may hinder signal capability, the tightness ratio between ground and signal contacts can further improve the reliability of electronic connectors.
In many applications, electronic connector products are connected to printed circuit boards while installing other components, which means that the connector must be able to withstand the chemical processes and temperatures involved in the connection process. Introducing resistant materials to make connectors compatible with the assembly process will increase the cost of the connector system and must be balanced with packaging density requirements.
