5 Pin Connector Challenges and Solutions:
Johoty’s 5 pin connector achieves the ultimate balance between power density and contact reliability
Engineer’s Challenges: Achieving up to 50A continuous current within a customized rectangular/circular housing. Ensure the ultra-low impedance and long lifespan of the plunger under vibration and impact. Traditional solutions often compromise between increasing contact area and maintaining contact force, which affects size, insertion and removal sensation, and wear.
Johoty’s solutions:
Technology: Johoty’s high current pogo pins use precise four finger or six finger contacts internally, rather than single point contacts. This increases the effective contact area, reduces the current density and contact resistance per unit area.
Material: Customized tempered beryllium copper or titanium copper alloy springs provide constant and optimal contact force. Far exceeding the yield strength and stress relaxation resistance of ordinary phosphor bronze. At -40 ° C to 125 ° C, the contact force attenuation rate is less than 5%, and the performance attenuation after 10000 insertions and removals is negligible.
5 pin connector solves the structural contradiction between IP67 protection and magnetic attraction alignment
Engineer’s challenges: The presence of strong magnets poses a challenge to the compression of the sealing ring and the structure of the shell. Imperfect magnetic alignment may cause distortion and wear of the sealing ring. Leakage occurs during harsh temperature cycling and pressure changes, resulting in IP67 waterproof failure.
Johoty’s solutions:
Mechanical design: Johoty designed the magnet to float axially, allowing for small adaptive movements within the housing cavity. Regardless of the angle at which the male and female 5 pin connector are attached, the magnet can prioritize precise alignment. Subsequently, the housing was perfectly closed, completely eliminating the shear of the sealing ring caused by misalignment.
Sealing system: using housing main seal, Pogo Pin secondary injection sealing, and PCB board level third layer sealant protection. Customize the main sealing ring material according to the oil resistance, high and low temperature resistance of the customer’s application. Under the action of magnetic attraction and housing mechanical locking, an impermeable barrier is formed.
Customized 5 pin connector for signal integrity and production consistency
Engineer’s challenges: Customization of single/double rows, rectangles/circles may lead to complex crosstalk and impedance control of high-speed signals.

FAQ
Engineer Challenge: You claim that the current is ≤50A per pogo pin. Is this continuous current or peak current? How to ensure that your 5 pin connector can still stably pass 50A current after 100,000 connections under continuous high load, high temperature rise, and unstable contact impedance? I also want to control its temperature rise within the safe range ΔT<30°C?
Professional solutions:
Materials and processes ensure stable, expected low contact resistance:
Core material: Pogo pins are made of C18150 chromium zirconium copper or equivalent high-strength, high conductivity copper alloy, rather than ordinary brass. The surface coating adopts a wear-resistant hard gold coating with a thickness of ≥ 1.27μm. The Plunger tip is coated with gold with a thickness of ≥2μm, ensuring low resistance and excellent corrosion resistance.
Key design: Adopting a multi-point or surface contact structure instead of a simple point contact pogo pin design. Increase effective contact area, reduce current density, and fundamentally suppress temperature rise. Internally, high-performance Elgiloy, Inconel, or SUS631 springs are used. The pre clamping force is precisely calculated to maintain a stable contact pressure even in a vibrating environment.
Thermal management and verification:
Design simulation: Use ANSYS or equivalent software for electrical thermal coupling simulation. Simulate the temperature field distribution of each part of the 5 pin connector under a continuous current of 50A. Optimize pogo pin layout and barrel heat dissipation design.
Actual test data: Johoty provides third-party certified test reports. Apply 50A DC at an ambient temperature of 25°C. Steady state temperature rise data after 2 hours, as well as comparison of current carrying capacity and temperature rise curve after 100,000 cycles. The data proves that the performance degradation of Johoty’s 5 pin connector is within the allowable range of the specifications.
Engineer Challenge: The non-standard dimensions of rectangles or circles, combined with magnetic attraction, pose a huge challenge for sealing. The installation slot of the magnet itself and the gap between the insulation of the pogo pin and the housing are potential leakage points. How do you achieve customized 5 pin connector without sacrificing magnetic attraction and flexibility? Realize truly reliable IP67 protection that can withstand 96 hours of salt spray testing?
Johoty’s solution:
Multi-level sealing:
Interface sealing: Precise silicone or fluorosilicone sealing rings are on the mating surfaces of the male and female ends. By optimizing the compression and deformation rate of the sealing ring through FEA, effective sealing is available within the tolerance range.
Structural sealing:
Pogo pin sealing: Using liquid silicone LSR encapsulation molding process, combining pogo pins with insulators at the molecular level. Completely eliminate leakage gaps along the pogo pins.
Magnet sealing: Johoty designs independent cavities for magnets, which are sealed and cured with epoxy resin or silicone to form a sturdy secondary barrier.
Housing sealing: Injection molding is effective at the housing joint to achieve body sealing. Between the housing and cable, achieve overmolding to form a complete IP67 and IP68 seal.
Strict verification standards:
Johoty performs air pressure tests including 85°C high-temperature hot water immersion test and high-low temperature cycling from -40°C to 125°C. As well as long-term salt spray corrosion testing, the aging performance and structural integrity of the sealing material are very high.
Engineer Challenge: The advantage of magnetic connectors is convenience, but the difficulty lies in how to reduce accumulated assembly tolerances and facilitate blind insertion smoothly? Can precise concentricity and axial alignment be achieved during each docking at this time? To avoid poor contact or damage to pogo pins caused by lateral shear forces?
Johoty solution:
Collaborative design of magnetic circuit and mechanical guidance:
Principle of leading and trailing suction: A guide cone or guide column is designed on the housing of the 5 pin connector. Before the magnet is fully attracted, the mechanical guide structure will first make contact and preliminarily correct its position. Guide the 5 pin connector to the final docking position. This avoids the possibility of misalignment caused by pure magnetic attraction.
Magnetic optimization: Through magnetic circuit simulation, accurately calculate engineers’ required magnetic force. A strong magnetic force can ensure the vibration/pulling resistance of the 5 pin connector connection. Cannot have excessive magnetic force to avoid affecting user experience or causing docking impact. Johoty will provide the optimal magnetic gradient curve for a 5 pin connector based on the weight and usage of the customer’s device.
Stress relief design for pogo pin:
- Pogo pin is designed with a floating margin within the housing of the 5 pin connector. Allow pogo pins to have slight adaptive displacement in the radial direction to absorb the alignment deviation of male/female 5 pin connectors.
- The sloping design of the o plunger tip helps the 5 pin connector slide smoothly into the correct position when slightly misaligned. Johoty provides a force stroke curve diagram for engineers to clearly understand the mechanical characteristics of the 5 pin connector docking process.
