Abstract
A plug with an overload protection function comprises a shell body composed of a shell body upper cover and a shell body lower cover, a cable conductor which is extended in the shell body, an L-pole pin, an N-pole pin and an E-pole pin, wherein the L-pole pin, the N-pole pin and the E-pole pin are arranged on the shell body lower cover, an overload protector is arranged in the shell body, an input end of the overload protector is connected with the L-pole pin through a jumper wire in a spot-welding mode, and an output end of the overload protector, the N-pole pin, the E-pole pin and the cable conductor are all correspondingly connected in spot-welding mode. As the overload protector is connected in series between the L-pole pin and a power line, the plug has the function of overload protection. When electrical appliances are electrically connected through the plugs, electrical appliance damage caused by overload can be avoided, and the plug has the advantages of function of protecting electrical appliances and extremely convenient use.
Description
(1) technical field
The utility model belongs to the power connector technical field, relates in particular to a kind of plug with overload protection function.
(2) background technology
Plugs and sockets is a requisite power connector spare in people's live and work.Existing plug directly is communicated with power supply when electrical equipment uses, when supply voltage has fluctuation or the bearing power that connected when surpassing plug rated power, cause circuit overheated easily, even cause fire.Therefore, there is potential safety hazard in this plug.
(3) summary of the invention
Have above-mentioned deficiency in the prior art in order to overcome, the utility model provides a kind of performance simple in structure, easy to use, safe the high plug with overload protection function.
The technical scheme in the invention for solving the technical problem is: a kind of plug with overload protection function; comprise the housing formed by case top lid and housing lower cover, stretch into the cable in the described housing and be located at L utmost point latch, N utmost point latch and the E utmost point latch that covers under the housing; also be provided with an overload protective device in the described housing; the input of described overload protective device is connected with the spot welding of described L utmost point latch by wire jumper, the output of described overload protective device, N utmost point latch, the spot welding connection all corresponding with cable of E utmost point latch.
The beneficial effects of the utility model are: since this plug at internal series-connection an overload protective device; this overload protective device is serially connected between L utmost point latch and the cable; when using the plug power taking; when circuital current surpasses rated current; overload protective device cuts off the power supply automatically; the electrical equipment that can avoid causing because of overload damages, thereby reaches protection electrical appliance and safety utilization of electric power purpose.Therefore, the utlity model has the high advantage of performance simple in structure, easy to use, safe.
