A New Type of Crystal Head Wiring Automatic Breaking Protection Plug

Abstract

The invention discloses a novel crystal head type wiring automatic open-circuit protection plug, belongs to the field of wiring plugs. According to the novel crystal head type wiring automatic open-circuit protection plug, by simulating the wiring mode of the net wire crystal head, under the action of a separated air bag and a heat conduction limiting rod, when a current is too high, the temperature of the wire rises, through a heat conduction mechanism and a transverse heat conduction rope, the heat conduction limiting rod is heated, so that the heat conduction rod is exploded through being heated, the compressed insulating gas at the internal portion of the heat conduction rod is released, the amount of the gas in the separated air bag is improved, the expansion of the separation air bagis remarkably accelerated, and a left magnetic plug and a right magnetic plug are separated towards the two sides under the longitudinal limiting effect of the heat conduction limiting rod; through cooperation with the self-fuse sheet, separation of the plug can be further accelerated, the plug is more sensitive to over-high current, and after separation of the plug and the self-fuse sheet, the laminated insulating sheet falls down between the plug and the self-fuse sheet, thereby effectively reducing the probability of accidental contact between the plug and the laminated insulating sheet, and reducing potential safety hazards.

Description

technical field [0001] The invention relates to the field of connection plugs, and more specifically relates to a novel crystal head type connection automatic circuit breaker protection plug. Background technique [0002] The amount of current that is allowed to pass continuously in an electrical circuit without overheating the wire is called the safe current carrying capacity or safe current. If the current flowing through the wire exceeds the safe current carrying capacity, it is called wire overload. Generally, the maximum allowable working temperature of the wire is 65°C. When overloaded, the temperature exceeds this temperature, which will cause rapid aging of the insulation and even burn the circuit. In machinery, when the shaft exceeds the load it can bear, the overload protection can prevent the damage of the equipment caused by overload. In microelectronics, when the current somewhere in the circuit is too large, the overload protection can automatically cut off ...

Problems solved by technology

[0003] In the prior art, for the protection of abnormal current, fuses are often used, and the protection of excessive current is achieved by blowing the fuse on the fuse. However, in this way, the blown fuse needs to be removed and reinstalled when it is used next time. For new fuses, this operation is too cumbersome and less convenient to use, and the fuses on existing fuses are usually connected by screw tightening or welding. During use, the wiring is easily corroded The situation will cause the fuse to loosen or even disconnect, which will affect the accuracy of the over-current protection and pose a great safety hazard.
