Connecting device for anticorrosive titanium clad copper bar and positive plate connecting substrate

The utility model belongs to a connecting device for an anticorrosive titanium clad copper bar and a positive plate connecting substrate. The connecting device comprises the titanium clad copper bar and the positive plate connecting substrate, wherein the positive plate connecting substrate is positioned below the titanium clad copper bar, and titanium bolts are arranged on the titanium clad copper bar; an upper titanium gasket, a polytetrafluoroethylene gasket, a lower titanium gasket and a titanium screw cap are sequentially sleeved on each titanium bolt from top to bottom; the titanium clad copper bar and the positive plate connecting substrate are positioned between the polytetrafluoroethylene gaskets and the lower titanium gaskets. The connecting device disclosed by the utility model has the beneficial effects that the easily-corroded part of the titanium clad copper bar is isolated from a copper sulfate solution by using the polytetrafluoroethylene gaskets, so that the service life of the titanium clad
