In the figure: 1. a housing; 2. an electromagnetic coil; 3. a detection mechanism; 4. an electronic component board; 5. a feedback signal hole; 6. a live wire electricity taking hole; 7. a zero line power taking hole; 8. an arc extinguishing chamber; 9. an indicator light.
Detailed Description
Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model. In the description of the present utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "upper surface", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.
Referring to fig. 1, an embodiment of the present utility model is provided: the semi-automatic charge control miniature circuit breaker comprises a shell 1, wherein an arc extinguish chamber 8 is arranged in the shell 1, and an electronic component board 4 is arranged on one side of the arc extinguish chamber 8; the electronic component board 4 is provided with a feedback signal hole 5, a live wire power taking hole 6 and a zero line power taking hole 7; the electromagnetic coil 2 is further arranged above the electronic component board 4, the electronic component board 4 is used for controlling the starting of the electromagnetic coil 2 to complete tripping action, and the detection mechanism 3 arranged on the shell 1 provides an opening and closing signal for the electronic component board 4.
The external provides the on/off control level voltage signal to the chip, so that the chip provides the voltage signal to control the on and off of the controllable silicon, thereby controlling the starting of the electromagnetic coil.
In summary, by optimizing the layout of the electronic component board 4, the arc extinguishing chamber 8 and the electromagnetic coil 2 in the housing 1, the internal layout of the housing 1 is reasonable, the space utilization rate is high, and particularly, the internal structure of the housing 1 can be simplified and the volume of the housing 1 can be reduced while the automatic power-off is realized.
Further, since the light guide column 9 is further disposed on the housing 1, and the light guide column 9 is connected with the indicator light of the electronic component board 4, it is convenient for a user to observe the working state of the device through the light guide column 9, for example, when the switch is closed, the red light is displayed to be on, and when the switch is opened, the red light is displayed to be off.
On the basis of the scheme, the zero line electricity taking hole 7 is close to the arc extinguishing chamber 8 and is connected with the negative electrode of the power supply through a lead. Therefore, the device for controlling the opening and closing of the N-pole circuit breaker can directly take electricity from the inside of the N-pole circuit breaker. The external control equipment is convenient to take power; and secondly, the power line is exposed as little as possible, so that the external structure of the N-pole circuit breaker is optimized. Based on the above, the utility model has simple structure, but the utility model not only can simplify the power taking mode due to the simple structure, but also can reduce the processing and manufacturing cost of the N-pole circuit breaker.
