Abstract
A plug comprises an insulating casing and a pin and is so structured such that a protective tube and a button type self-locking switch serially connected in a circuit are arranged in the insulating casing, and two ends of the insulating casing are elastically stuck by two protective tube clips to ensure good contact. One pin is connected to an outer guiding wire via a protective tube, and the other pin is connected to another outer guiding wire via the switch. After a plugged power device is used, the switch on the plug is switched off to cut off power without frequently plugging plug. The plug is convenient for use and increases the service lifetime of the plug and the socket. When the consumption power is overloaded or short circuit occurs after the plug is used, the power can be automatically cut off to prevent damage of electric appliance or occurrence of fire hazard, to eliminate hidden trouble and to ensure power safety.
Description
Technical field
The utility model relates to a kind of electric elements, especially a kind of plug.
Background technology
Plug is the critical component that power consumption equipment is connected with power supply, applies very extensively, and current known plug, only plays the effect of circuit switch, there is no defencive function.When electric power after the plug is greater than the bearing capacity of plug or short circuit, can burn out plug, socket and other electrical equipment, or cause and cause heavy losses by fire.Existing plug does not have switch on the other hand, in daily life and work, be finished after electrical equipment, people's custom is closed the switch of power consumption equipment, but still charged between from plug to power consumption equipment, there is unsafe factor, relatively the way of insurance is to pull out plug, but it is very inconvenient often to plug plug, and easily damages plug and socket.
Summary of the invention
[0003] the purpose of this utility model is: a kind of plug with protective tube and switch is provided, in the time that the power consumption equipment after plug is stopped using, can close the switch circuit breaking on plug, do not need often to plug plug, and electric power after the plug is while being greater than the bearing capacity of plug or short circuit, can auto power off.
Scheme of the present utility model is: with the plug of protective tube and switch, comprise insulation crust and pin, its design feature is: in insulation crust, be provided with the protective tube and the push button self-lock switch that are connected in circuit, the two ends of protective tube are flexibly blocked by two Insulating tube clip, guarantee insurance pipe and good the contacting of protective tube clip.A pin of plug is connected on an outer guide line by protective tube, and another pin is connected to after by switch on the outer guide line of another root.
The beneficial effects of the utility model are: after power consumption equipment is finished, close the switch on plug, cut off the electricity supply, do not need often to plug plug, and easy to use, and the life-span of increase plug and socket.Moreover be electric power overload after the plug or circuit while being short-circuited, can auto power off, avoid damaging electrical equipment, even cause fire, remove a hidden danger, ensure Electrical Safety.
