Abstract
An electric-connection wire holder structure mainly solves problems that an output terminal of an existing small-size circuit breaker with an electric leakage protection function moves in a terminal block, and the existing small-size circuit breaker is poor in stability. The electric-connection wire holder structure is characterized in that a terminal block (5) consists of an upper terminal block (6) and a lower terminal block (7) which are fastened with each other, the lower terminal block (7) is provided with a slot (8), an inserting plate (9) is arranged on the upper terminal block (6), and a connecting plate (3) of an output terminal (4) is positioned inside the slot (8) of the lower terminal block (7) and pressed by the inserting plate (9) on the upper terminal block (6). Since the output terminal of the electric-connection wire holder structure is fixed into the terminal block and cannot move, the electric-connection wire holder structure is fine in stability and convenient in wiring, and is safe and reliable.
Description
Technical field
The utility model relates to a kind of miniature circuit breaker, is specifically related to a kind of electrical connection junction block structure.
