New description: [New technical field] [0001] This creation is about a bipolar automatic power-off safety switch, especially one that can cut off the power supply in addition to the preset circuit overload, and can be synchronously cut. Break the safety switch structure of its associated loop power supply. [Prior Art] [0002] At present, the most common electrical safety protection measures are between the power supply line and the electrical appliance, such as a fuse or a circuit breaker, to cut off the current when the current is too large, but Since the fuse must be replaced after each blow, it is extremely inconvenient to use and has been gradually eliminated. The circuit breaker is not suitable for being on each line or the power end of each appliance at the same time due to its complicated structure and high price. It is used and the traditional circuit breaker is installed at each power supply end. The installation and related circuits are too complicated. Therefore, the general circuit breakers are made into larger current specifications, and several currents are smaller. The circuit shares a circuit breaker, so that the sensitivity of the circuit breaker can not meet the safety requirements of various electrical circuits with different rated currents. At the same time, the power supply terminals of several circuits collectively share a circuit breaker to limit the overall load current. Structure, if the circuit breaker has an overload and power failure, the overloaded electrical or short circuit cannot be correctly known immediately, and must be separately Fee with the spirit of the time detection, parties can learn the above message, this does not have electrical knowledge for those who are extremely troubled by the matter.

However, since the button 7丄 and the interlocking piece 71 in the above structure are directly pivoted, If there is continuous overload or short circuit in the circuit, and the general user does not have the knowledge of professional power consumption, it will be re-tested again without warning. At this time, due to the linkage piece 711 Directly pressed by the button 71 and pressed down, without any protection measures, it is very likely to cause the possibility of sparking high heat when pressing. The user is in a very dangerous state and causes damage to the electrical device, and cannot In line with the current European protection measures for electrical safety, this is indeed a direction for improvement.

The upward and downward pressing force of the bimetal is maintained by the oscillating elastic piece, and in the overload or short circuit state, the bimetal is thermally deformed to be separated from the other conductive pin to cut off the power supply, and at the same time Push the swing The sheet is pushed against the top to push the toggle device to produce a bend, so that the pressing body can no longer drive the bimetal through the toggle device to maintain the state of tripping and disconnection before the overload condition is improved, thereby forming a safe and perfect circuit. Overload protection [0005] However, in many applications, there are often multiple different auxiliary power circuits that must be powered by a main power circuit (ie, when the main power circuit stops supplying power, it must The situation of cutting off the power supply of each auxiliary power circuit), but the above various protection switches with overload power-off function have not seen the structure and function of such synchronous power-off, forming an application deficiency and deficiency, and also In view of the above-mentioned shortcomings of the overloaded power-off safety switch, the creators have researched and improved the shortcomings of these shortcomings, and finally have this creation.
