PURPOSE:To connect a terminal pin at three positions to the printed board side at a high contact pressure by holding strongly the terminal pin, which is the central contact of a contact plug installed to an apparatus case by pressing in a holding piece of a screw device, with a feeder piece and a pair of feeder shafts connected to the feeder piece. CONSTITUTION:By pressing a holding piece 5 against a pair of springs 8 with a screw device 43, a pair of feeder shafts contacted to the holding piece 5 through a feeder piece 6 are guide by a guide device 44, compressing the springs 8 while narrowing the interval gradually, and contacted to the both side surfaces of the feeder piece 6 and the terminal pin 24. In this case, since the diameter of the feeder shafts 7 is larger than that of the terminal pin 24, the feeder shafts 7 contact the lower and side surface of the terminal pin 24, and the terminal pin 24 receives the depressing force of the feeder piece 6 and the upward component force of the pair of feeder shafts 7, denying the displacement substantially. And since the pressing forces in the three directions increase proportionally to the pressure to the holding piece 5, the contacts of the terminals can be connected securely with a high contact pressure. |
