In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention; the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance; furthermore, unless expressly stated or limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, as they may be fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example (b): referring to fig. 1, the integrated reset trip actuating mechanism includes a fixing base 1, a down-pressure spring 2, a reset pull rod 3, a fixed point cross arm 4, a winding coil 5, a fixed electrical connection point 6, a movable electrical connection point 7, an indication sheet 8 and a movable clip 9, wherein the reset pull rod 3 is disposed on the upper portion of the down-pressure spring 2, the fixed point cross arm 4 is connected with the winding coil 5, the fixed electrical connection point 6 is disposed below the fixed point cross arm 4, the indication sheet 8 is disposed on the movable clip 9, and one end of the indication sheet 8 is provided with the movable electrical connection point 7. The winding coil 5 further comprises an iron core 10.

The working principle is as follows:

each electrical connection point is in a tripped (separated) state:

the product is in the dropout (separation) state, and activity electrical connection point 7 is in the separation state with fixed electrical connection point 6, and the product does not circular telegram, and activity checkpost 9 is located fixing base 1 bottom, and reset pull rod 3 is in the off-state with activity checkpost 9.

The structure is in the on (bonded) state:

according to the technical scheme, the reset pull rod 3 is pressed, the movable clamp 9 is pushed by the iron core 10 when a certain position is pressed, the reset pull rod 3 and the reset pull rod 3 are buckled, when the reset pull rod 3 and the movable clamp 9 are buckled, the reset pull rod 3 is loosened, the reset pull rod 3 and the movable clamp 9 are upwards pulled due to the force of the spring 2 which is pressed downwards, the indication plate 8 is enabled to ascend to be connected to a movable electric connection point and a fixed electric connection point, and a product is in a conduction state.

The structure is about to trip (disconnect) state:

when the structure winding coil has an action signal, the winding coil generates electromagnetic force to pull the iron core 10 to move, the iron core 10 pulls the movable clamp 9 to trip, the indication sheet 8 has pressing elasticity on the movable clamp 9, so that the movable clamp 9 rapidly falls down, the movable electric connection point and the fixed electric connection point are separated instantly, the structure is tripped, and the state is recovered again.

The integral reset and tripping actuating mechanism structure provided by the utility model adopts a buckle type press-pull tripping, has the advantages of simple structure, sensitive action, short tripping execution time and few component parts, realizes large moment and small tripping force due to the selection of the buckle type movable clamp for tripping, and can effectively improve the reliability of a finished product and reduce the manufacturing cost.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
