An electrical signal taking-out device is disclosed which is less subject to external electromagnetic waves and which is capable of obtaining a proper wave form and a properly measured value. The device includes a pair of metal wires, a metal retaining member for holding the metal wires to permit grip portions of the metal wires disposed at distal ends thereof to be opened and closed, and an actuating mechanism for actuating the metal wires to open and close the grip portions of the metal wires, whereby electrical signals taken out by the metal wires are adapted to be inputted to measuring equipment through the retaining member.

Electrical signal taking-out device

An electric signal taking-out method and a device therefor capable of taking out electric signals for measurement easily from opposite ends of an arbitrary chip part soldered to a circuit board. A pair of contact elements having sharp distal ends and bent obliquely inward are arranged so that the distal ends thereof face each other. The contact elements are shifted inward by a holding member so that the distal ends bite into solder joints by which the chip part is soldered to the circuit board. The contact elements are held in the biting state so that electric signals are taken out independently from the respective contact elements.

Electrical signal read-out method and device therefor

A clip structure for extracting electric signals for measurement, which is improved in accuracy and reliability, and which can be handled easily. In the clip structure, an operating member is rotatably supported in a hollow base member with one end projecting from the base member, and urged in a specified direction. A cylindrical member is provided at the front end of the base member. Elastic wires are stored in the cylindrical member and grip portions are formed in the front portions of the elastic wires, while the rear portions are fixed to a lower portion of the operating member. The grip portions are configured to project from the front end of the cylindrical member when pushed in a direction opposite to an urging force and rotated. A contact pin member is disposed at a lower portion of the base member. One end of the contact pin member is engaged with the rear end of the cylindrical member while the other end is projected from the base member. The portion where the one end of the contact pin member and the rear end of the cylindrical member engage with each other is connected by welding such as soldering. A core material such as steel is inserted into the contact pin member.
