PURPOSE:To electrically connect between each plug and plug blacket fittings under the condition that an oxide film of the connecting part between these fittings is broken by thrusting and impacting the plug in/to the sectional corner- like connecting part of the plug blacket fittings. CONSTITUTION:Connecting surfaces 3 of which sectional radiuses are gradually increased in proportion to the distance from the leading ends of rod-like plugs 1, 2 are formed on the external peripheries of these plugs 1, 2. Connecting parts 6 consisting of sectional corners as sharp as the oxide films on the connecting surfaces 3 are broken are formed on the inner surfaces of plug blacket fittings 4, 5. Moreover, elastic bodies 7 are fitted to the plugs 1, 2 or plug blacket fittigs 4, 5 and the plugs 1, 2 or the plug blacket fittings 4, 5 are thrusted in respective axial directions to impact between said connecting surfaces 3 and connecting parts 6. |
