Abstract

A contact device having a rotatable static contact (10) and of a circuit breaker comprises a static contact (10) that is embedded in a static contact support (40). The static contact support (40) is internally provided with a static contact spring (50) and a locating shaft used for mounting the static contact spring (50). The static contact support (40) is further internally provided with a shaft body passing through the static contact. The shaft body comprises a central shaft (71) passing through the axis of rotation of the static contact, and a bearing shaft (21) passing through the static contact (10) and limiting the static contact spring (50). A locating shaft (70) is sleeved with the static contact spring (50). Spring arms extending out from two ends are snapped to the bearing shaft passing through the static contact (10). The static contact (10) of the device of the utility model is rotatably mounted on the static contact support (40), a repulsive force is generated on the contact to allow a moving contact and the static contact (10) to overturn at the same time, and then an electric arc is prolonged and arc blow-out is accelerated. A step surface passing through the shaft body of the static contact (10) is used for limiting the two sides of the static contact (10) to effectively prevent the static contact (10) from moving in the axial direction of the shaft body, ensure a contact area of the moving contact and the static contact, effectively reduce assembling difficulty and improve assembling efficiency.
