Detailed Description

The utility model is further described below with reference to the accompanying drawings: as shown in the figure, the multifunctional key structure of the circuit breaker comprises a shell 1, wherein a control circuit board 2 is arranged in the shell, a micro switch 3 is arranged on the control circuit board, a movably matched button 4 is also arranged on the shell, a through groove 110 is arranged on the shell, the button comprises a main board 41, and the main board is movably matched with the through groove; the main board is provided with a contact arm 42, a first gear slot 411, a second gear slot 412 and a locking slot 44, a gear block 11 is arranged in the shell, the main board comprises a first position where the gear block is arranged in the first gear slot and the contact arm is contacted and pressed with the button, and a second position where the gear block is arranged in the second gear slot and the locking slot extends out and is used for locking outside the shell. The buttons on the control circuit board can be test buttons or other multifunctional buttons, such as long-press and short-press to realize different functions, such as short-press is test buttons, long-press is Bluetooth matching, the using method of the locking groove is that when the locking groove is exposed out of the shell, the buttons are prevented from being pressed down again through a pin shaft and the like (refer to CN216849816U in the prior art), when the locking groove is locked, the linkage plate is not rotatable, and therefore an operating mechanism of the circuit breaker cannot be switched on, and error switching on is prevented. And a reclosing mechanism is also arranged in the shell and is controlled by the control circuit board.

In this embodiment, as shown in the drawing, the first gear slot is an elongated slot. The long press, the short press and the like can be realized in a segmented manner.

In this embodiment, as shown in the figure, a linkage plate 5 is disposed in the housing, a linkage rod for connecting with an operating mechanism of the circuit breaker is disposed on the linkage plate, and a stop block 45 is disposed on the main board, and is used for blocking cooperation with the linkage plate when the main board is in the second position. When the main board is in the second position, the stop block is in blocking fit with the linkage plate, and at the moment, the linkage plate cannot rotate towards the closing direction of the circuit breaker.

In this embodiment, as shown, the gear block includes a base 111, and an arc-shaped convex surface 112 that mates with the first gear groove and the second gear groove is circumferentially provided on the base. The arc convex surface is matched with the inner walls of the first gear groove and the second gear groove to realize positioning, and the first gear groove and the second gear groove are communicated through the connecting groove, so that the arc convex surface is smooth when sliding.

In this embodiment, as shown in the figure, a baffle 113 is disposed on the top of the base, and the baffle is correspondingly disposed above the motherboard. The baffle can prevent that the mainboard from deviating from, makes overall structure more stable.
