POGO PIN is a very fine probe. It has the characteristics of small size, light weight, beautiful appearance, long life, high current and high corrosion resistance, suitable for product structure engineers to design and use a variety of complex structures.
POGO PIN is a Spring-Type Probe Connector that is formed by riveting three parts of a needle tube (Tube), a needle, and a spring through a precision mold. Also known as Spring Loaded Pins, Spring-Loaded Connector, Probe, etc.
The bottom of the needle (Plunger) of the POGO PIN is usually inclined. The function of the inclined structure is to ensure that when the POGO PIN is working, it uses the spring force to push the needle to generate a lateral force so that the needle (Plunger) and the needle tube (Tube) ) Maintain stable contact with the inner wall, and let the current mainly pass through the gold-plated needle and the needle tube to ensure a stable and extremely low contact impedance.
POGO PIN is a very fine probe. It has the characteristics of small size, lightweight, beautiful appearance, long life, high current, and high corrosion resistance. It is suitable for product structure engineers to design and use a variety of complex structures, thereby broadening product design Designer’ design ideas and reduce product design cycles and costs.
POGO PIN is often used in the precision connection of mobile communication terminals, mobile phones, smartwatches, earbuds Bluetooth wireless headsets, automobiles, medical, aerospace, and other electronic products.
Needle oblique tail structure (standard products can pass 2A current)
The tail slope structure causes the needle axis to deviate to generate lateral force
The lateral force provides good and stable contact between the needle surface and the inner surface of the needle tube. At the same time, using the principle of current conduction to a conductor with low resistance and good conductivity, the current is mainly conducted through the gold-plated needle and the needle tube.
Built-in steel ball structure
The gold-plated steel ball makes the surface contact area larger for better performance and can pass more current. According to the size, the material and the electroplating are different, the current can pass 5A, 10A, 15A, or more.
The compression times of the mechanical motion of the spring, the corrosion resistance of the plating layer and the surface wear will affect the service life of the Pogo Pin. Rtench has developed and accumulated oval spring structure design technology, needle oblique tail structure design, original non-destructive riveting and closing technology and vacuum Blind hole plating technology greatly improves the service life of Pogo Pin.
Data collection mobile terminal host and battery are plugged in for 100,000 times.
Performance comparison of Pogo Pin mechanical motion compression times before and after life.
Before the life test of Pogo Pin, Observe dynamic force and impedance curve changes, Confirm whether the strength and contact resistance of the working stroke range are within the required range of the drawing.
After Pogo Pin life test, Observe dynamic force and impedance curve changes, Confirm whether the strength of the working stroke range and the contact impedance are within the scope of the drawing requirements.
Rtench not only sends materials and Pogo Pin samples to the authoritative testing and certification organization SGS of Switzerland for environmental protection certification such as ROHS & REACH SVHC every year. Samples will also be sent to SGS for environmental-related tests and verification. Environmental tests include adjustable temperature salt spray test, artificial sweat test, thermal shock test, electrochemical corrosion resistance test, and high temperature and humidity test.
