1. A device for measuring the electrical contact between two electrical conductors of an electrical circuit, comprising:

  • a frame formed of electrically insulating material and including two hollow cylinders each defining an axis, said frame adapted to be placed in a measuring position in which the conductors are received in said cylinders,two electrically conductive elements mounted on said frame adjacent respective ones of said cylinders and adapted to be electrically connected to a current generator, said elements mounted for movement toward and away from respective ones of said axes in directions transversely thereof, each of said elements including a concavely curved surface facing a respective one of said axes,first holding means for moving said elements toward said respective axes and against respective ones of said conductors when said frame is in said measuring position, for securing said frame to said conductors and establishing a current flow between said conductors when said elements are connected to said current generator,two electrically conductive pins mounted on said frame adjacent respective ones of said cylinders for movement toward and away from respective ones of said axes in directions transversely thereof,second holding means for moving said pins toward said respective axes and into electrical contact with respective ones of said conductors when said frame is in said measuring position, said pins contacting said conductors at locations in said electrical circuit disposed between said two elements, andmeans for measuring the difference in potential between said pins.
