SPRING CONTACT PIN ARRANGEMENT.

摘要

The invention relates to a spring contact pin arrangement having a spring contact pin that comprises a pin housing in which a contact element is mounted so as to be longitudinally displaceable and is loaded by a spring device acting opposite to a displacement direction, wherein the contact element is connected to at least one first interface of the spring contact pin arrangement and protrudes from the pin housing with a contact region for electrical contacting of an electric test item. According to the invention the spring contact pin arrangement comprises a position sensor, wherein the contact element, in order to transfer the stroke thereof, is connected to a displaceable sensor element of the position sensor detecting the stroke position of the contact element. The aim of the invention is to prepare a particularly stable and highly concentrated solution or dispersion of at least one self-assembling protein, said solution or dispersion posing no health risk and/or being particularly environmentally friendly and allowing for efficient or improved production of molded articles or sheet material made of pure protein as well as protein impregnations or coatings in a large variety of fields of application. According to the invention, the protein solution or protein dispersion comprises, in an aqueous solution or dispersion, at least one physically stabilized self-assembling protein having a protein concentration of 5 to 35 wt.%, preferably 5 to 30 wt.%, especially preferably 5 to 25 wt.%, relative to the total weight of the stable solution or dispersion, in particular with a stability of at least 5 hours, preferably more than 12 hours, especially preferably more than 20 hours or even more than 48 hours. No added chemical stabilizer is included or required.
