Abstract
The utility model discloses a cable with detectable terminal temperature function. Increase temperature sensor on the plug insert with electrical apparatus connection cable, for the temperature protect function who provides the plug with electrical apparatus. Specific sketch map as follows: sense the temperature as temperature sensor and be greater than when setting for the temperature, can realize the cable auto -power -off, play the guard action. Setting up temperature sensor in plug department and can reducing the excess temperature time, reduced temperature is too high to the damage with electrical component. This kind of cable that has a terminal temperature sensing effect realize the virtual control that connects the condition from contact terminal, reaches to prevent because the virtual accident potential such as conflagration that cause that connect.
Description
Technical field
The present invention relates to cable and use the technical field of safety, particularly relate to that a kind of have can the cable of detection terminal temperature function.
Background technology
The plug virtual connection of electrical appliance can cause electrical appliance work abnormal, owing to contact resistance is big, having part power consumption on joint, sparkles and even burn, causing conductor joint heating, until blowing.The ground resistance per square of electric wire virtual connection is because greatly loose contact, real contact area reduces, be equivalent to wire cross-section area reduce, line can be that the sectional area with electric wire is directly proportional by the ability of electric current, the electric wire of each specification has specified size of current, meet and exceed this specified electric current, will be hot.The place of electric wire virtual connection, is not that complete electric wire connects, is simply increased by all electric currents, electric current density by sub-fraction copper cash, so heating.Contact resistance is very big, and heating is burnt red, not by occur overcurrent protective switch will not action because air switch only just meeting action in the case of overcurrent.The conductor joint heating caused due to electric wire virtual connection, the not phenomenon of overcurrent, so while virtual connection causes sparking at plug, produce arc light heating, belong to serious loose contact, form the personal injuries such as the excessive heating of instantaneous touch electric current, serious meeting initiation fire.
Summary of the invention
It is an object of the invention to for technological deficiency present in prior art, and provide that a kind of have can the cable of detection terminal temperature function.
For realizing the purpose of the present invention, the technical solution adopted in the present invention is: a kind of have can the cable of detection terminal temperature function, described cable includes plug, described plug includes plug upper casing, plug drain pan, a L pole inserted sheet, G pole inserted sheet and the 2nd L pole inserted sheet, a described L pole inserted sheet and the first temperature sensor contact, described 2nd L pole inserted sheet and the second temperature sensor contact, described first temperature sensor, the second temperature sensor are connected with controller, and described controller and line disconnection mechanism connect.
Wherein, described first temperature sensor and the second temperature sensor are critesistor.
Wherein, described line disconnection mechanism is the relay being connected in supply line, and described relay is connected with controller.
Wherein, described line disconnection mechanism includes relay and the neon lamp being in parallel with relay and is worth greatly resistance.
Compared with prior art, the invention has the beneficial effects as follows: this utility model discloses a kind of cable with terminal temperature sensing effect.The plug slice that electrical appliance connects cable increases temperature sensor, the temperature protection function of plug is provided for electrical appliance.Concrete schematic diagram is as follows: when temperature sensor senses to temperature is more than design temperature, can realize cable and automatically power off, play a protective role.Temperature sensor is set at plug and can reduce the excess temperature time, reduce the too high damage to electrical appliance components and parts of temperature.This cable with terminal temperature sensing effect realizes the control to virtual connection situation at contact terminal, reaches to prevent the accident potential such as the fire that causes due to virtual connection.

Wherein, described first temperature sensor and the second temperature sensor are critesistor.
Wherein, described line disconnection mechanism is the relay being connected in supply line, and described relay is connected with controller.
Wherein, described line disconnection mechanism includes relay and the neon lamp being in parallel with relay and is worth greatly resistance.
Compared with prior art, the invention has the beneficial effects as follows: this utility model discloses a kind of cable with terminal temperature sensing effect.The plug slice that electrical appliance connects cable increases temperature sensor, the temperature protection function of plug is provided for electrical appliance.Concrete schematic diagram is as follows: when temperature sensor senses to temperature is more than design temperature, can realize cable and automatically power off, play a protective role.Temperature sensor is set at plug and can reduce the excess temperature time, reduce the too high damage to electrical appliance components and parts of temperature.This cable with terminal temperature sensing effect realizes the control to virtual connection situation at contact terminal, reaches to prevent the accident potential such as the fire that causes due to virtual connection.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
