Power supply inserted terminal with wave-projecting protection function

Abstract

The invention discloses a power cuttage grafting end provided with surge protection function, which can solve a surge produced by the switching of a power system load (Switching Surge), or a surge directly or indirectly produced by a lightening (Lightning Surge), and can further protect electric products from the damage of the surge. The power cuttage grafting end mainly comprises a cover layer formed between power and plugs, wherein, the cover layer is provided with a hollow space, an electrical escape orifice runs through the hollow space of the cover layer; two terminals are arranged in the cover layer apart from each other in certain distance; the tail ends of two terminals are respectively and electrically connected with the plug; when instantaneous high pressure and the surge happen, the hollow space and the electrical escape orifice form an electrical escape discharge path to protect load circuit by using the point discharge of the terminals.

Description

technical field [0001] The present invention relates to a plug-in terminal for a power supply, in particular, a covering layer with a hollow space and a terminal is formed between the transformer plugs, and the covering layer is matched with the discharge terminal to discharge the power supply of instantaneous high-voltage surge socket end. Background technique [0002] With the miniaturization of electronic components, semiconductor components have become processing and control circuit components in general electrical products or high-tech industries. Semiconductor components reduce the size of electrical products, but greatly improve their functions. However, limited by its own characteristics, it is relatively weak against power surges. Therefore, how to effectively protect electrical products will not cause function loss or damage due to surges, and even cause electric shocks and fires that endanger consumption. The personal safety of the victims has become the directio...

Problems solved by technology

Whether it is a load switching or a surge generated by lightning, it may have varying degrees of impact on indoor electrical appliances, ranging from damage to electrical products, to causing a short circuit in household appliances or causing a fire

[0003] In electrical appliances or power systems, it is common to use fuses or non-fuse switches as circuit breaker protection for electrical products during instantaneous high voltage or overload, and the response time of the aforementioned components is about 2 milliseconds (ms), but the surge The generation is extremely short in microseconds (us), and the energy generated by the surge has damaged electrical products before common protection components can react in time
