PURPOSE:To make brazing easy and efficient by providing a cam mechanism which operates clampers and performing operations such as change-over of a clamping state, press contact and movement of the clampers, conduction of electricity, etc. at prescribed timings in the process for turning a cam. CONSTITUTION:A cam body 35 is turned by a lever 37 to drop pins 25, 26 into cam grooves 41, 42 and to weaken springs 22-24, then clampers 1, 2 clamp a brazing material 66 between tentatively clamped metallic conductors 64 and 65 and set the conductors between grasping parts 3A-6A. The lever 37 is then turned to eject the pins 25, 26 from the grooves 41, 42 and to clamp thoroughly the clampers 1, 2 by means of the springs 23, 24. The lever 37 is further turned to press the cam body 35 toward the axial center direction by the effect of both cam faces 43, 44 of the cam bodies 35, 36 and the effect of a spring means 50. The lever 37 is again turned to conduct electricity to terminals 48, 49 by a switch operation 37A. Easy brazing is thus made possible without errors by a series of the operations. |
