A connector mechanism with the following features:- Constant (precise, accuracy < 1%) force throughout the working range.- The working range depends on the reinforcement of force. Current 3mm, can be changed to 2mm/1mm or any.- Fully mechanical.- Resistant to any shocks and accelerations.- Has the option of compensations for spring aging (over time and in the process of temperature changes).- Precise adjustment of the actually assembled device, to compensate for the inaccuracy of the spring manufacturing.- Multiple use, for testing, for force measurements.- Weight 800 grams, for the entire system.- The thickness can be increased to accommodate other springs if required.- The system uses two pairs (125N + 125N = 250N), which ensures uniformity and symmetry of the load in relation to the support points.- Different working springs are used for different forces (50-200, 250 in the example). Strength adjustment changes this partially by 10%- It has a transport position. Automatic unfolding when released from the container.- Generates a constant force, rather than rigidly fixing the parts. In the working range and the entire period of use.- If necessary, additional properties may not be implemented, which significantly simplifies the design.- Has an inertial shock mechanism. Which does not affect accuracy and does not create sticking. Strikes only at the moment of connection.
