Abstract
The invention discloses a novel overcurrent protector, comprising a housing, a first inserting sheet, a second inserting sheet, and a metal sheet. The front surface of the housing fastens a front cover, and the top is fastened with a pressing plate. The pressing plate supports a board in a cavity through springs on two lower sides. The board is provided with a guiding moving block which is provided with a moving groove inside. A moving sheet is installed in front of the guiding moving block through a rotating point. One end of an adjusting hook is joined with the pressing plate, and the other end is inserted in the moving groove of the guiding moving block. The first inserting sheet, the second inserting sheet, and a third inserting sheet are embedded in the bottom of the housing in sequence at equal interval. The top of the first inserting sheet is provided with an arc-shaped metal sheet through a fixed joint. The metal sheet is under the moving sheet, the end of the metal sheet is clamped in the hook formed on the tail of the moving sheet. The top of the second inserting sheet is disposed under the metal sheet, and the second contact on the top is connected with the first contact on the metal sheet in a contact manner. Beneficial effects of the novel overcurrent protector are that the protector is novel in structural design, complete in function, convenient in operation, and the protector effectively protects a circuit and prevents electric appliance element from being burnt out.
