Abstract

A plug with an overload protection function, comprising a housing composed of an upper cover and a lower cover of the housing, a cable extending into the housing, and an L pole pin and an N pole arranged on the lower cover of the housing. The plug and the E-pole plug, the housing is provided with an overload protector, the input end of the overload protector is connected to the L-pole plug by spot welding through a jumper, the output end of the overload protector, the N-pole plug, The E-pole plug and the cable are both corresponding to the spot welding connection. Since an overload protector is connected in series between the L-pole plug and the power cord, the utility model has an overload protection function. When an electrical appliance is powered through this plug, it can avoid electrical damage caused by overload, and has the function of protecting the electrical appliance. The function of electrical appliances is very convenient to use.

Description

A plug with overload protection function

(一)技术领域(1) Technical field

本实用新型属于电源连接器技术领域，尤其涉及一种具有过载保护功能的插头。The utility model belongs to the technical field of power supply connectors, in particular to a plug with an overload protection function.

(二)背景技术(2) Background technology

插头插座是人们生活和工作中必不可少的电源连接器件。现有的插头，在电器使用时直接连通电源，当电源电压有大幅波动或所连接的负载功率超过插头额定功率时，容易造成电路过热，甚至引起火灾。因此，这种插头存在安全隐患。Plug and socket is an indispensable power connection device in people's life and work. The existing plug is directly connected to the power supply when the electrical appliance is in use. When the power supply voltage fluctuates greatly or the connected load power exceeds the rated power of the plug, it is easy to cause the circuit to overheat and even cause a fire. Therefore, there is a potential safety hazard in this plug.

(三)发明内容(3) Contents of the invention

为了克服现有技术中存在上述的不足，本实用新型提供一种结构简单、使用方便、安全性能高的具有过载保护功能的插头。In order to overcome the above-mentioned shortcomings in the prior art, the utility model provides a plug with overload protection function which is simple in structure, convenient to use and high in safety performance.

本实用新型解决其技术问题的技术方案是：一种具有过载保护功能的插头，包括由壳体上盖和壳体下盖组成的壳体、伸入所述壳体内的电缆线、以及设于壳体下盖上的L极插销、N极插销和E极插销，所述壳体内还设有一过载保护器，所述过载保护器的输入端通过跳线与所述L极插销点焊连接，所述过载保护器的输出端、N极插销、E极插销与电缆线均相对应的点焊连接。The technical solution of the utility model to solve the technical problem is: a plug with overload protection function, including a housing composed of a housing upper cover and a housing lower cover, a cable extending into the housing, and a The L-pole pin, the N-pole pin and the E-pole pin on the lower cover of the housing are also provided with an overload protector in the housing, and the input end of the overload protector is connected to the L-pole pin by spot welding through a jumper wire. The output end of the overload protector, the N-pole pin, the E-pole pin and the cables are all correspondingly connected by spot welding.

本实用新型的有益效果在于：由于这种插头在内部串联了一个过载保护器，该过载保护器串接在L极插销与电缆线之间，在使用插头取电时，当电路电流超过额定电流时，过载保护器自动断电，能够避免因过载而造成的电器毁坏，从而达到保护用电电器和安全用电目的。因此，本实用新型具有结构简单、使用方便、安全性能高的优点。The beneficial effect of the utility model is that: since the plug is connected in series with an overload protector inside, and the overload protector is connected in series between the L-pole pin and the cable, when the plug is used to take power, when the circuit current exceeds the rated current , the overload protector automatically cuts off the power, which can avoid the damage of electrical appliances caused by overload, so as to achieve the purpose of protecting electrical appliances and using electricity safely. Therefore, the utility model has the advantages of simple structure, convenient use and high safety performance.
