Detailed Description
The utility model is further described below with reference to the accompanying drawings: as shown in the figure, the signal transmitting mechanism of the molded case circuit breaker comprises a base 1, a rotating shaft 2 is arranged in the base, a moving contact 21 is arranged on the rotating shaft, a switch assembly 3 is arranged in the base, the switch assembly comprises a switch 31, the rotating shaft is provided with a touch part 22, and the touch part is used for touching the switch when the rotating shaft rotates so as to transmit a signal of the position of the rotating shaft. The signal transmission device can be used for connecting the switch with the main circuit board of the molded case circuit breaker in a signal mode, so that the signal is transmitted to the main circuit board, the signal transmission device and the main circuit board can be connected through a wire, an indicator lamp can be arranged on the base, the indicator lamp can be controlled through the switch, and particularly, the switching-off touch or switching-on touch can be realized by setting the position of the switch according to actual conditions.
In this embodiment, as shown, the switch assembly further includes a gang board 32 that is detachably connected to the base. The switch assembly can be conveniently installed on the base, and the use is more convenient.
In this embodiment, the switch is mounted on the gang board as shown. The switch can be arranged on the group board in a plugging mode and the like.
In this embodiment, as shown in the figure, a supporting wall 11 is disposed in the base, a clamping groove 111 is disposed on the supporting wall, and the group board is in plug-in fit with the clamping groove. The thickness of the assembled plate is matched with the width of the clamping groove, positioning can be realized after the assembled plate is assembled, disassembly and assembly are convenient, and connecting pieces such as screws are not needed.
In this embodiment, as shown, the support wall is provided with an open slot 112 for receiving the switch. The switch is convenient to expose, and can be closer to the rotating shaft.
In this embodiment, as shown in the drawing, the touch portion is a boss disposed on a circumferential outer wall of the rotating shaft. Through boss touching switch, the contact surface of boss and switch can be the arcwall face to promote more smoothly.
In this embodiment, as shown in the figure, the switch is provided with an elastic piece 33, and the touch part is disposed opposite to the elastic piece and pushes the elastic piece when the rotating shaft rotates. The elastic sheet has elastic force for keeping an initial state, namely, as shown in fig. 1, the bottom of the elastic sheet can be provided with a button of a switch, when the elastic sheet is pushed by the touch part, the button is pressed down against the elastic force to realize the switch switching, and meanwhile, the elastic sheet can return to the initial position by virtue of the elastic force after no stress.
