As shown in the figure is a domestic acupoint electrotherapy instrument. The whole circuit is mainly composed of a six Schmitt trigger CD40106, which consists of Dl, Rl, VDl and C1 ultra-low frequency multivibrator, the oscillation frequency is 0.5 ~ 5Hz, adjusted by RPl.
Cold And Heat Shrinkable Tube
Cold shrink tubing is an open ended rubber sleeve, made primarily from rubber elastomers with high-performance physical properties, that has been factory expanded or pre-stretched, and assembled onto a supporting removable plastic core.Cold shrink tubing shrinks upon removal of the supporting core during the installation process and the electrician slides the tube over the cable to be jointed, terminated or abandoned and unwinds the core, causing the tube to collapse down, or contract, in place. Cold shrink tubing is used to insulate wires, connections, joints and terminals in electrical work. It can also be used to repair wires, bundle wires together, and to protect wires or small parts from minor abrasion. It needs storage in controlled environments with temperatures not exceeding 43 degrees celsius.
The heat shrink tubing is a shrinkable plastic tube used to insulate wires to provide wear resistance and environmental protection for stranded and solid wire conductors, connections, joints and terminals in electrical work. It can also be used to repair insulation on wires or bundle them together to protect wires or small parts from minor wear and create cable entry seals that provide environmental seal protection. Heat shrink tubing is typically made of nylon or polyolefin that shrinks radially (but not longitudinally) to between one-half and one-sixth of its diameter upon heating.
