The core of the spring pogo pin connector design
The design and material selection of the spring thimble connector are the key points for successful size reduction. The core of the design is the elastic pin. To become high contact strength, low contact resistance, and maintain performance in thousands of plugs and unplugs, beryllium copper materials with special tensile annealing properties must be selected. The main specifications of the thickness and length of the beryllium copper and the shape can ensure the long life and long performance of the spring thimble micro connector pin.
Spring pogo pin connector insulation shells are mostly injection molded liquid crystal polymer, and some old designs use polyphenylene sulfide. When the insulator between the spring pins is only 10~11 mils at the 0.025" pitch, this insulating material still has high retention and high electrical insulation strength. The high-reliability PogoPin thimble connector body can be used in plug-in and low-end Made of insulating material for vibration applications, but the highest vibration and high shock applications require a metal housing.
Durability is determined by a good installation design. Force and acceleration are key elements for testing the strength of spring thimble connectors in harsh applications. Because of the reasonable mounting bracket, the nano spring thimble connector can withstand vibration and shock of more than 10000Gs, such as under fire and launch conditions.
Compared with nano-circular pogo pin connectors and nano-circular pogo pin connectors, the mini-circular pogo pin connectors (0.050" pitch) are particularly large. When installing pins and sockets with a pitch of 0.025" In the same circular area, up to 4 times as many interconnected devices can be used. Most of the current requirements of the new circuit are less than 1A. Because of the digital processing, smaller wire gauge wires are used in the cable assembly to adapt to the nano circular connector. Therefore, the total weight and diameter of the interconnection system are greatly reduced. An additional benefit of nano cables is increased flexibility since cables with smaller diameters are easier to route in tightly restricted locations.
