The present invention further sets: one end of the connecting sheet is bent downward to be electrically connected to the terminal, the other end of the connecting sheet extends horizontally toward the socket hole to the socket hole, and this end is provided with a resisting shrapnel, when the power-taking PCB When the board is inserted into the socket hole, the power-taking piece on the power-taking PCB board is electrically connected with the resisting shrapnel.

The present invention further provides that: the connecting piece is provided with a fixing groove, one end of the conflicting elastic piece is fixed in the fixing groove, and the other end is bent upward to form a conflicting portion.

Beneficial effects of the present invention: when power-taking needs to be assembled, one end of the power-taking PCB board is directly inserted into the socket hole of the housing, the power-taking piece on the power-taking PCB board is electrically connected to the connecting piece, and the power-taking PCB board The male plug on the other end is aligned with the female plug on the automatic reclosing switch to achieve power acquisition. Compared with the traditional technology, the power-taking piece on the power-taking PCB board is connected by plugging, and does not need to be welded to the terminal of the circuit breaker. At the same time, because the power-taking PCB board is placed in the socket hole, there is no need to cover the power-taking PCB board to protect it through the cover plate. At the same time, the power-taking PCB board is connected to the automatic reclosing module through the female plug and the male plug. The structure Simple and easy to assemble.
