Claim 1
Independent Claim
285 words
A contactless connector circuit comprising: first electric circuit means including a semiconductor switch which is adapted to be rendered on and off alternately in response to an input pulse signal; a first coil, connected in series with said semiconductor switch of said first electric circuit means, for generating a first magnetic flux when energized by the conduction of said semiconductor switch; a first case securely enclosing said first coil therein; a second coil for generating a first a.c. signal in response to the changes of sair first magnetic flux during the magnetic coupling with said first coil; a second case securely enclosing said second coil therein and detachably mating with said first case to cause the magnetic coupling between said first and second coils; conductor means connected to said second coil for transmitting said first a.c. signal; a third coil, connected to said conductor means, for generating a second magnetic flux in response to the changes of said first a.c. signal applied through said conductor means; a third case securely enclosing said third coil therein; a fourth coil for generating a second a.c. signal in response to the changes of said second magnetic flux during the magnetic coupling with said third coil; a fourth case securely enclosing said fourth coil therein and detachably mating with said third case to cause the magnetic coupling between said third and fourth coils; and second electric circuit means including another semiconductor switch connected to said fourth coil for reshaping said second a.c. signal into an output pulse signal, said another semiconductor switch being responsive to one of positive and negative polarities of said second a.c. signal such that said output pulse signal is synchronized with said input pulse signal.
