| 摘要 | PURPOSE: To improve the rigidity of a contact to prevent the contact from being damaged by the impact form generated when the contact is closed by providing a beam having a substantially thin section along the whole length, a means connected to the beam to mechanically connect a contact operating mechanism to a horizontal bar, and providing an insulating partitioning means. CONSTITUTION: A horizontal bar 10 has a molded part 12 and a horizontal bar beam 14, and the molded part 12 has four insulating barriers 16, three contact blade mounting parts 20 and two horizontal bar beam insulating parts 22 for insulating the horizontal bar between the insulating barriers 16. The beam 14 has two link mechanism connecting parts 18, a substantially I-shaped beam member 32 and a molding tub 34, and each link mechanism connecting part 18 has two tubs 36 mounted on the beam member 32. Thus, a lightweight type horizontal bar having sufficient rigidity can be provided. COPYRIGHT: (C)1990,JPO |
