4 Pole Measuring Aligator Clip for Milliohm Meter with seperate Current and Voltage Path
Description
This is a first implementation of my 4 pole milliohm meter test clamp. You see if you want to accurately test small resistance values you need to keep the current and the voltage path separated. Hence the need for 4 poles. Even though the clip can feature up to 4 poles each clip, likely most times I will use two pairs of clips for axial components. The clip is designed for 20mm long 7,5 mm diameter extruder springs like these I am selling in my Ebay store ( https://www.ebay.de/itm/183819685405 ) Note that you can use 2 identical pieces of each version (2 or 3), but version 2 components alone require a spring that is longer than 20 mm to grip tight! Use only a pair of version 3 to get a tight grip with the Springs I offer. A M3 20mm screw and M3 nut for each clamp or a piece of 3mm filament can be used to assemble each clamp. These clamps are going to be used in my open source component tester ( https://github.com/usertogo/NanoBatteryTester001 ) that eventually is supposed to be able to evaluate and sort all types of parts (Batteries, fuses, diodes, Solar cells, etc) required for solar electromobility applications. Anyhow if you want to follow my exploits and general project to advance clean solar muscle electric mobility you can do that at: https://www.patreon.com/SunTripToGo Comments, remixes (freeCAD source included) and questions are welcome...
