The new demand of product, the requirement as the mating power supply line of electric equipment products are also higher and higher.However, existing power supply line product exists
Following deficiency: the current-carrying core wire that traditional two cores or multiple core cord are enclosed with insulating layer by more respectively is constituted, general household
Mating ac power cable usually has L, N, E the pole piece line for being purely by way of power delivery function, when due to poor contact or aging, short
The reasons such as road cause electric wire using that can not accomplish to power off in time when the temperature is excessively high, if continuing transferring high voltage or voltage to electric appliance
Equipment necessarily causes equipment to be undermined and brings unnecessary economic loss.
Summary of the invention
The object of the invention is that solving the disadvantages described above of the mating power supply line of electric equipment products, providing one kind has overheat certainly
The power supply line of disconnected defencive function being capable of intelligent-induction and general when power supply line temperature caused by unusual condition is more than set temperature
The electric wire that power supply line abnormal heating signal passes through special intelligent temperature sensor in time is transferred to equipment built-in controller, and controller is certainly
Dynamic cut-off equipment general supply, protection circuit use safe.
For this purpose, according to the present invention, providing a kind of power supply line with overheating protection function, the power supply line is coated on
Multiple current-carrying core wires in external insulation layer, each current-carrying core wire include the current-carrying conductor coated by insulating layer, wherein the power supply
Line further includes overheating protection unit, and the overheating protection unit and the multiple current-carrying core wire are arranged in the external insulation layer parallel
It is interior, and core wire is incuded including at least one temperature detection, the temperature detection induction core wire includes the temperature coated by insulating layer
Conductor is detected, wherein the outside of temperature detection induction core wire is coated with shielded layer.
According to above-mentioned technical concept, the present invention can further comprise any one or more following preferred forms.
In certain preferred forms, the overheating protection unit includes incuding core by two temperature detections of shielded layer cladding
Line.
In certain preferred forms, the current-carrying core wire and the overheating protection unit one that are coated by the external insulation layer
Body extrusion moulding.
In certain preferred forms, the shielded layer is made of copper foil, aluminium foil, tinfoil paper or conductive rubber.
In certain preferred forms, the temperature detection conductor is twisted by multiple conducting wires, and the size of the conducting wire is small
In the size of the conducting wire of the current-carrying conductor.
The defencive function that there is power supply line of the invention overheat to autotomy, when power supply line since poor contact, overcurrent etc. are abnormal
, can be with disconnecting circuit when situation causes power supply line temperature to be more than set temperature, protection circuit avoids temperature is excessively high from making using safe
At security hidden troubles such as the damage of circuit caused by the reasons such as power supply line aging circuit, short circuit and fire incidents.Meanwhile the power supply
Cable architecture is simple, it is low in cost, convenient for manufacture and use, can be widely applied to various household electrical appliance.
Detailed description of the invention
Other feature and advantage of the invention will be more preferable by the preferred embodiment being described in detail below in conjunction with attached drawing
Ground understands.Identical appended drawing reference identifies same or similar component in attached drawing, in which:
Fig. 1 is a kind of transverse sectional view of the power supply line with overheating protection function of preferred embodiment of the present invention；
Fig. 2 is the partial longitudinal sectional view of power supply line shown in Fig. 1.
Specific embodiment
The implementation and use of embodiment is discussed further below.It will be appreciated, however, that the specific embodiment discussed only shows
Illustrate to plasticity to implement and use ad hoc fashion of the invention, the range being not intended to limit the present invention.
As depicted in figs. 1 and 2, the power supply line according to the present invention with overheating protection function is coated on external insulation layer
Multiple current-carrying core wires in 1, such as two-phase or three-phase core wire.In the illustrated embodiment, L, N, E pole piece line are respectively corresponded including
Three current-carrying core wires 2,3,4, each current-carrying core wire include by insulating layer coat current-carrying conductor, wherein in figure with number 5,
6,7 mark current-carrying conductor.
The present invention be advantageously provided in external insulation layer 1 with current-carrying core wire 2,3,4 parallel arrangement and with current-carrying core wire one
The overheating protection unit of body extrusion moulding, which includes at least one temperature detection induction core wire, in shown reality
It applies in mode, illustrates two temperature detection induction core wires 8,9, each temperature detection induction core wire includes by insulating layer packet
The temperature detection conductor covered detects conductor with digital 10,11 scaling temps in figure.For current-carrying conductor 5,6,7, temperature inspection
Conductor 10,11 is surveyed to be twisted by the lesser more thin wires of size.Advantageously, the external packet of temperature detection induction core wire 8,9
It is covered with shielded layer 12, the current-carrying core wire 2,3,4 and transmission temperature for by the shielded layer 12 transmission telecommunications number being worked to electrical appliance
Degree signal is to the temperature detection induction core wire 8 of electrical appliance, the synchronization of 9 signals and does not interfere with each other, so that the power supply line is simultaneously
Have the function of that overheating protection and power delivery and signal are transmitted.
In some embodiments, shielded layer 12 is metal screen layer, such as is made of copper foil, aluminium foil, tinfoil paper；Alternatively,
Shielded layer can also be made of conductive rubber.
In alternate embodiments, external insulation layer 1, the insulating layer of cladding current-carrying conductor 5,6,7 and temperature of plate detection
The insulating layer of conductor 10,11 can by being made with the high-elastic abrasion-proof insulating material such as certain thickness PVC so that cored wire conductor it
Between mutually insulated and with power supply line exterior insulation.In addition, the outside of external insulation layer 1 can also be equipped with certain thickness protective case, example
Such as it is made of nylon, polyethylene, polypropylene.
After power supply line of the invention is applied to electrical appliance, if power supply input is excessively high, load current increases, electricity
Source line and electric appliance junction are heated up suddenly or temperature is raised to warning value, such as 40 DEG C~120 DEG C, and temperature detection conductor 10,11 will
Temperature signal can be transmitted to electrical appliance, electrical appliance is cut off the power, and then is reduced power supply line temperature and protected electrical equipment.If
Power supply line and electrical appliance poor contact lead to sparking, draw electric arc, generate the high current of short time and power supply line is caused rapidly to heat up,
When increasing climbing value more than preset temperature, temperature detection conductor 10,11 can send temperature signal to electrical appliance also with disconnecting circuit,
Protection circuit uses safe.
