FAQ
Core challenges addressed by engineers:
Engineers are concerned that customization may sacrifice performance. Non-standard design may result in uneven contact force, coating wear, or material stress changes. Ultimately causing impedance fluctuations, heating, and decreased signal integrity. This is unacceptable in precision measurement or high current applications.
Johoty’s solutions:
Johoty ensures performance through a systematic collaborative design process, rather than post remediation:
Joint simulation of contact mechanics and impedance: During the structural design phase, Johoty uses simulation software to analyze the matching of plunger shape, spring force, and stroke. The goal is to maintain the optimal 50g-200g spring force within the defined work schedule. Calculate the theoretical contact impedance of the 2 pin connector.
Accurate selection of materials and coatings: Based on your current and durability requirements, Johoty will recommend the most economical coating combination and thickness. For high durability requirements, we recommend palladium cobalt alloy (Pd Co) plating tips instead of conventional gold coatings. Due to its higher hardness and corrosion resistance, 2 pin connector can maintain stable low impedance.
Process tolerance control and 100% electrical testing: Johoty will clarify key dimensions, including needle roundness and spring preload. Perform 100% contact impedance and instantaneous on-off testing on each pogo pin after production. Ensure that all 2 pin connector shipped meet simulation expectations.
Challenges to be solved:
Vibration can cause micro motion wear at the contact interface, damage the coating, form insulating oxides, and ultimately lead to connector failure. Temperature and humidity will accelerate corrosion, and engineers have to prepare quantitative and reliable protection plans.
Johoty’s solution:
Johoty focuses on eliminating the root cause of micro motion wear and providing comprehensive barrier protection:
Anti micro motion wear design:
High retention design: Johoty provides high standard insertion and extraction retention by adding harpoon spring or optimizing the shell buckle structure. In a vibrating environment, the male and female sockets of the 2 pin connector do not loosen.
Optimal contact geometry: Adopting a large radius spherical or inclined contact design to maximize the contact area. Johoty converts relative sliding into elastic deformation, fundamentally reducing wear.
Comprehensive sealing strategy:
Shell level sealing: The female seat can integrate silicone or fluororubber sealing rings to achieve IP67/IP68 protection.
Pogo pin sealing: using pre gold-plated spring loaded pin and LSR coated injection molding. Form a perfect seal between pogo pins and plastic housing to prevent moisture from entering from the roots.
Rigorous environmental verification: Johoty provides test reports based on MIL-STD vibration and IEC 60068 temperature and humidity cycling to demonstrate the reliability of the 2 pin connector with data.
Challenges to be solved:
When a 2 pin connector needs to transmit high-frequency signals of sensor readings or mix transmission power with sensitive signals. At this point, parasitic inductance, capacitance, and crosstalk between pins can seriously degrade signal quality.
Johoty’s solution:
Johoty designs the 2 pin connector as a miniature transmission line, rather than a simple mechanical conductive component:
Modeling and simulation first: Using 3D electromagnetic field simulation CST to extract the insertion/return loss and near-field coupling of pogo pins under customized layout. This can predict and optimize signal integrity in the early stages of design.
Targeted layout and shielding scheme:
High frequency signal: Johoty suggests using a 2 pin connector with a coaxial structure to wrap the signal pogo pin within a ground shielding layer. Provide a definite impedance control of 50Ω and excellent anti-interference ability.
Power and signal mixing: Johoty optimized the spacing and relative position of 2 pogo pins through simulation. Add a grounding isolation pillar or a shielding wall integrated into the plastic housing between two pogo pins. Johoty’s 2 pin connector reduces crosstalk to an acceptable level of <-40dB @ 1GHz.
