Description

Socket with resettable temperature protection

This creation is about a socket with resettable temperature protection, especially refers to a kind of not only can power off when the circuit is overloaded and heated, it really makes the electrical equipment more safe in use, and its structure is simple and small in size. The overall assembly is more simple and convenient, and can effectively reduce the production cost. It can reduce the probability of failure and damage and increase its service life. The innovative design of the socket with reversible temperature protection is more practical in its overall implementation. By.

According to the press, the use of electricity is inseparable from the lives of modern people. Most of the various electrical appliances are connected by using power plugs and mains sockets through the wires, and the electrical appliances are supplied by the wires to transmit electricity. Generally, wires, plugs, sockets, etc. have their rated voltage and current capacity. When the delivered voltage and current exceed their rated load, the metal parts of the wires, plugs, sockets, etc. will start to heat, which will cause burnout and cause dangerous accidents. Things happen, which poses a potential threat to the safety of people's lives and property.

However, most users have no idea about the electrical specifications, and they will not be equipped with instruments to measure whether the wires are overloaded. Therefore, when the wires are overloaded and overheated, the user will not be able to detect the frequent occurrence of fire due to the call line.

As a result, an industry has developed a bulletin No. I602361 “Power Plug with Intelligent Thermal Protection Mechanism” announced on October 11, 2017, which includes: a current sensing unit to sense a conductivity flowing through the power plug The current of the pin; a first temperature sensing unit, which is arranged inside a housing of the power plug, to measure the temperature of a conductive pin; a second temperature sensing unit, to measure an ambient temperature; and a control Unit, coupled to the current sensing unit, the first temperature sensing unit, the second temperature sensing unit and a controllable switch, wherein the controllable switch is electrically connected in series to the conductive pin, the control unit is based on the The current of the conductive pin measured by the current sensing unit and the ambient temperature measured by the second temperature sensing unit are calculated to obtain a temperature threshold, and the first temperature sensor is determined according to the temperature threshold Whether the temperature of the conductive pin measured by the measuring unit is over temperature; wherein, when the temperature of the conductive pin is judged to be over temperature, the control unit turns off the switch to disconnect the current flowing through the conductive pin Current.

However, the above "power plug with intelligent thermal protection mechanism" can achieve the expected effect of breaking the current when the temperature of the conductive pin is judged to be overtemperature, but it is also found in its actual operation and use. The overall component composition is more complicated, which not only causes it to be more inconvenient in assembly design, but also relatively prevents the manufacturing cost from being effectively reduced. In addition, due to the complicated component composition, the probability of failure and damage increases, resulting in improvements in the overall structural design. Space.
