PURPOSE:To adjust the parallelism of a clamping plate easily with high precision by extending or narrowing a slit between the nose sections of first and second fixed plates by a screw and adjusting the parallelism of the clamping plate. CONSTITUTION:When the opposed angles of clamping plates 6, 7 take a value shown in (a) after assembling a wire clamper, a male screw 15 is screwed to a female screw 14, and a slit 12 is expanded until the clamping plates 6 and 7 are made parallel and the positional relationship of the nose sections 2a, 2b of first and second fixed plates is changed. When the opposed angles of the clamping plates 6, 7 take a value shown in (c), a male screw 16 is screwed to a female screw 13 from the female 14 side together with a washer 17, and the slit 12 is narrowed until the clamping plates 6 and 7 are made parallel and the positional relationship of the nose sections 2a, 2b of the first and second fixed plates is altered. Accordingly, the parallelism of the clamping plates 6, 7 in the longitudinal direction of a wire 5 can be adjusted easily with high accuracy, thus preventing the damage of the wire on clamping, then improving the quality of wire bonding. |
