Abstract: A disconnector and a method for manufacturing the disconnector are disclosed in the present application. The disconnector includes conductive arms pivotally coupled with each other, and finger contacts. The finger contacts have two opposite ends and an elastic portion between the two opposite ends, each of the finger contacts being fixed to the respective conductive arm by fasteners at the two opposite ends such that the elastic portion presses against the conductive arm. In response to the conductive arms being pivoted toward each other and clamping an electrical contact hanged at a bus-bar above the disconnector, the conductive arms are electrically coupled with the electrical contact via the respective finger contacts. A method of manufacturing a disconnector is also disclosed.

Abstract: A disconnector (100) and a method for manufacturing the disconnector (100) are disclosed. The disconnector (100) includes conductive arms (110) pivotally coupled with each other, and finger contacts (111). The finger contacts (111) have two opposite ends (115, 116) and an elastic portion (113) between the two opposite ends (115, 116), each of the finger contacts (111) being fixed to the respective conductive arm (110) by fasteners (112) at the two opposite ends (115, 116) such that the elastic portion (113) presses against the conductive arm (110). In response to the conductive arms (110) being pivoted toward each other and clamping an electrical contact (200) hanged at a bus-bar above the disconnector (100), the conductive arms (110) are electrically coupled with the electrical contact (200) via the respective finger contacts (111). The disconnector (100) according to the present disclosure provides outstanding contact performances while the material costs as well as manufacturing and assembly costs are relatively low.
