Abstract
Voltage sample structure of electric leakage circuit breaker circuit board. The wire of mainly solving among the present voltage sample structure of electric leakage circuit breaker circuit board generally is directness and bimetallic strip welded, and in use breaks off easily like this, causes the problem of inefficacy. Its characterized in that: still including elastic component (5) that can electrically conduct, elastic component (5) one end with wire (4) are connected, the other end with the interference fit is supported in bimetallic strip (21). The utility model provides a voltage sample structure of electric leakage circuit breaker circuit board, the wire is connected with bimetallic strip through the elastic component that can electrically conduct, can provide the compensation at bimetallic strip deformation in -process, and the assembly is firm, simple structure, excellent in use effect.
