CLAMPING DEVICE

PURPOSE:To allow the stable holding of many plates by fitting the hook parts at the front end of clamping bars consisting of slender cross members into the aperture part of receivers mounted at both side ends of the pole plates at both ends of a stacked body of pole plates, thereby integrating the stacked body of the pole plates. CONSTITUTION:The clamping device of the stacked body of the pole plates is constituted of the clamping bars 10 and the receivers 20. The receivers 20 are mounted to approximately the center of frames 50a, 50b, etc., mounted at both side ends of the pole plates 50, 51 at both ends of the stacked body of the pole plates and the apertures 25a, 26a are opened at the end plates 25, 26 thereof. Projecting parts 25c, 26c and supporting parts 25b, 26b are provided therein. On the other hand, the clamping bars 10 consist of the slender transverse members 11 and the hook parts 13, 15 projectingly provided at both side ends thereof. The front ends 13a, 15a of the hook parts 13, 15 are formed to the shape curving upward. The hook parts 13, 15 of the clamping bars 10 are inserted into the apertures 25a, 26a of the receivers of this constitution and the front ends 13a, 15a of the hook parts are engaged and fixed with the projecting parts 25c, 26c. The plate unit 30 which prevents the generation of the short circuiting of the pole plates by the oscillation and contact of the pole plates is formed in this way.
