What is 2-Point Contact?
IRISO' 2-Point Contact refers to a connector design that has two contacts on the same line. By providing two contacts on a single terminal, the contact reliability of the connector is improved.
The benefits vary depending on the type of connector. FPC/FFC connectors offer stable conductivity through redundant connections, while Board to Board Connectors provide redundancy in addition to the benefit of removing foreign matter (self-cleaning).
2-Point Contact in FPC/FFC connectors
In FPC/FFC connectors, 2-Point Contact is primarily used for redundant connections. By providing two contacts, even if one contact becomes unstable, conductivity can be easily maintained through the other contact, contributing to connection stability.
Because FPC/FFCs use thin, flexible conductors for connection, careful consideration of the terminal structure is crucial to ensuring stable contact. 2-Point Contact is one effective method for improving contact reliability in such applications.
Advantages of adopting 2-Point Contact for FPC/FFC connectors
Using 2-Point Contact in FPC/FFC connectors makes it possible to solve a variety of problems.
- Redundant connections improve the stability of the connection.
- It ensures a stable contact state for thin, flexible conductors.
- Improved conductivity stability contributes to improved yield and cost reduction.
2-Point Contact in Board to Board Connectors
In Board to Board Connectors, 2-Point Contact is adopted not only for redundant connection but also for its effectiveness in removing foreign matter (self-cleaning).
Our 2-Point Contact refers to a structure in which two contacts are located on the same line.
What is foreign object removal (self-cleaning)?
This refers to the effect of removing foreign matter and oxide films by the friction between the terminals of a connector during Mating. This process is called wiping.
Even if foreign matter is attached to the other terminal, the first contact removes the foreign matter, and the second contact ensures conductivity to a better contact surface. This enables a stable connection that is less affected by minute foreign matter.
Advantages of adopting 2-Point Contact for Board to Board Connectors
Using 2-Point Contact in Board to Board Connectors makes it possible to solve a variety of problems.
- The two-point contact design contributes to improved connection stability.
- Foreign matter is removed during Mating even in environments where dirt is likely to occur.
- By reducing contact failures caused by foreign matter, this contributes to improved yield and reduced overall costs.
- We contribute to automation through robotic assembly.
