Abstract
The invention discloses a shield structure of a contactor. The shield structure comprises a shield body, which has a first inner cavity with a downward opening for receiving a main contact circuit installed on a pedestal. An upward protruding projecting part is arranged in the upper middle part of the shield body, and has a second inner cavity communicating with the first inner cavity, and the second inner cavity are divided into vertically through first chambers according to tandem arrangement. A plurality of installation parts for installing auxiliary static contacts are arranged on the two sides of the projecting part of the shield cover respectively. When the auxiliary static contacts are installed on corresponding installation parts, the inner side ends of the auxiliary static contacts extend into corresponding first chambers and match with auxiliary moving contacts of the contactor. The number of parts is reduced, die investment is effectively reduced, and instability risk of parts due to connection is minimized. The shield structure facilitates realization of automatic line assembling, directly isolates a main circuit explosion chamber from auxiliary contacts, and effectively increases the electrical distance of the main circuit explosion chamber and the auxiliary contacts.
