Description
Technical field
The utility model relates to electric equipment products field more particularly to a kind of safety plugs.
Background technique
With the improvement of living standards, the popularity rate of household electrical appliance is also higher and higher, the use of plug is also more and more extensive,
And there are many deficiencies for existing plug.
A kind of plug as disclosed in Chinese invention 105680241A, including header body and contact, the header body by
Plastics are made, and the contact number is two, and the contact is made of copper, and the contact is connected to external cable, the contact
It is located in the header body, the header body leading portion is simultaneously provided with protrusion, the protrusion close to the two sides of the contact
On be provided with sucker for locking-type plug, but the utility model is to reduce the generation of poor contact between plug and socket,
It is to be at a complete loss as to what to do to the raising of plug temperature anomaly caused by poor contact.
Utility model content
One, technical problems to be solved
For drawbacks described above present in the prior art, the lower problem of the safety in utilization of plug.
Two, technical solution
To solve the above problems, providing a kind of safety plug, including metal insert and power supply line, safety plug also wrap
It includes: thermistor, temperature-sensitive plastics and control module；
Metal insert includes firewire inserted sheet and zero curve inserted sheet；
Temperature-sensitive plastics are in contact with metal insert；
Control module detects the temperature value of temperature-sensitive plastics by thermistor, and is greater than default temperature in the temperature value detected
When angle value, the power-off signal for cutting off the power is cut off the power or issued to control module.
Wherein, safety plug further includes signal wire, and thermistor passes through signal wire and control module communication connection.
Wherein, control module is load control module.
Wherein, control module is earth leakage protective device control module.
Wherein, safety plug shell is made of fire proofing material.
Wherein, metal insert further includes ground wire inserted sheet.
Three, the beneficial effects of the utility model
Compared with prior art, the utility model takes full advantage of water heater controller, without being in addition plug configuration control
Device processed, reduces costs, but also the structure of plug is simpler.
The temperature that temperature-sensitive plastics are also detected by thermistor, when the temperature value that thermistor detects is more than preset value
When, water heater controller cuts off the power supply of water heater, improves the safety in utilization of water heater.
Detailed description of the invention
Fig. 1 is the perspective view of the utility model；
Fig. 2 is the module map of the utility model；
Fig. 3 is the internal structure chart of the utility model.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment cannot be used to limit the scope of the utility model for illustrating the utility model.
In a particular embodiment, the utility model is applied on water heater, thermistor is thermistor 1.
Embodiment 1:
As shown in Fig. 2, thermistor and control module communication connection；
In the present embodiment, control module is water heater controller.
As shown in figures 1 and 3,
L line and N line are electrically connected by metal insert with alternating current, and metal insert is in contact with temperature-sensitive plastics；
Water heater controller detects the temperature value of temperature-sensitive plastics by thermistor 1, and thermistor 1 and water heater control it
Between pass through 2 communication connection of signal wire.
When the temperature value that thermistor 1 detects is more than preset value, water heater controller cuts off the power supply of water heater.
And plug body has flame-retarded plastic to be made, even if plug temperature is excessively high, will not cause fire as common plastics
Calamity, so that the utility model is safer.
The present embodiment takes full advantage of water heater controller, is not necessarily to be in addition plug configuration controller, reduce costs,
So that the structure of plug is simpler.
The temperature that temperature-sensitive plastics are also detected by thermistor 1, when the temperature value that thermistor 1 detects is more than preset value
When, water heater controller cuts off the power supply of water heater, improves the safety in utilization of water heater.
Embodiment 2:
The present embodiment and the difference of embodiment 1 are, when the temperature value that thermistor 1 detects is more than preset value, heat
Water heater controller issues power-off signal to earth leakage protective device and cuts off the power after earth leakage protective device receives the signal.
It is thoroughly cut off the power by earth leakage protective device, improving is safety to be used.
Embodiment 3:
In the present embodiment, control module is earth leakage protective device control module；
Earth leakage protective device control module detects the temperature value of temperature-sensitive plastics by thermistor 1, when thermistor 1 detects
Temperature value be more than preset value when, earth leakage protective device control module control tripping coil cutting water heater power supply.
The control module of earth leakage protective device is made full use of, without being in addition plug configuration controller, reduces costs, also makes
The structure for obtaining plug is simpler
Embodiment 4:
The present embodiment is additionally arranged ground wire inserted sheet on the basis of embodiment 3, and the ground line of ground wire inserted sheet water heater is electrically connected
It connects, so that water heater effective grounding.
Embodiment of above is merely to illustrate the utility model, and is not limitation of the utility model, related technology neck
The those of ordinary skill in domain, in the case where not departing from the spirit and scope of the utility model, can also make a variety of changes and
Modification, therefore all equivalent technical solutions also belong to the scope of the utility model, the scope of patent protection of the utility model is answered
It is defined by the claims.
