Embodiment
Describe embodiments of the invention below in detail, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Be exemplary below by the embodiment being described with reference to the drawings, only for explaining the present invention, and can not be interpreted as limitation of the present invention.
As depicted in figs. 1 and 2, electric wire 2 of the present invention is at existing conductor wire core 26 and be coated between the external insulation layer 25 outside conductor wire core 26 and increased inner insulating layer 27 and conductive layer 24, and this inner insulating layer 27, conductive layer 24 and external insulation layer 25 are coated on outside conductor wire core 26 from inside to outside successively.For this kind of wire structure, in the time that external insulation layer 25 is worn, conductive layer 24 will contact with extraneous metal species support, if utilize this conductive layer 24 to form short-circuit alarming circuit, can make short-circuit alarming circuit because conductive layer 24 ground connection and form current return to report to the police, like this, even if just can repair by reminding user looking up the fault point, cause short circuit to prevent that electric wire from destroying to the position of conductor wire core 26.This conductive layer 24 adopts the metal conducting layer that is easy to form electric wire 2 of the present invention conventionally.
In order to strengthen the structural strength of electric wire 2, the inside surface of the inner insulating layer 27 of this electric wire 2 particularly fits with the outside surface of conductor wire core 26, i.e. gapless between the two.In like manner, the inside surface of this conductive layer 24 particularly fits with the outside surface of inner insulating layer 27.In like manner, the inside surface of this external insulation layer 25 particularly fits with the outside surface of conductive layer 24.
For the application scenario diameter of electric wire 2 to strict demand, in order not increase the diameter of origin wire 2, for electric wire 2 of the present invention, can make the thickness of the thickness sum of external insulation layer 25, conductive layer 24 and inner insulating layer 27 and the external insulation layer of origin wire suitable, in this kind of situation, can make the relative inner insulating layer 27 of external insulation layer 25 there is thicker thickness, to avoid the short-circuit alarming circuit of applying electric wire 2 of the present invention to produce prematurely warning, cause user to need the frequent alert event of processing.
For the ease of utilizing conductive layer 24 to form short-circuit alarming circuit, be convenient to conductive layer 24 to be connected to this short-circuit alarming circuit, electric wire 2 of the present invention can lead to wire harness connector 21 to the outside of external insulation layer 25 through conductive layer 24, can directly conductive layer 24 be connected to short-circuit alarming circuit by wire harness connector 21, and connect by the mode of destroying external insulation skin without the end from electric wire, and this kind of mode can also effectively be avoided occurring in junction problem in electrical contact separately because the destruction of syndeton causes conductive layer 24 and conductor wire core 26, and then can prevent that the phenomenon of false alarm from appearring in short-circuit alarming circuit.
For the ease of adopting electric wire 2 to form the current supply circuit of being powered for load 4 by power supply 1 as shown in Figure 4, can be provided for the joint in electric wire 2 places in circuit 22,23 at the two ends of electric wire 2, this joint and conductor wire core 25 are electrically connected, and electric wire 2 directly can be made to the finished product with jointing.
According to the applied environment that is connected to the accumulator positive polar curve between accumulator and automobile starter, this electric wire is particularly suitable for making accumulator positive polar curve, for accumulator positive polar curve, above-mentioned joint 22 can be the eyelet terminal that is connected with the power supply terminal of automobile starter be convenient to as shown in Figure 3, and joint 23 is battery positive voltage joint.
As shown in Figure 4, short-circuit alarming circuit of the present invention comprises the current supply circuit of being powered for load 4 by power supply 1, this short-circuit alarming circuit adopts above-mentioned any electric wire 2 to form this current supply circuit, short-circuit alarming circuit of the present invention also comprises the warning device 3 being connected between the positive pole of power supply 1 and the conductive layer 24 of electric wire 2, this warning device 3 is for example pilot lamp, also can be the warning devices 3 such as hummer, the embodiment of wire harness connector 21 is set for electric wire 2, and this warning device 3 can directly be connected with conductive layer 24 by wire harness connector 21.Be the embodiment of accumulator positive polar curve for electric wire 2, this power supply 1 is accumulator, and this load 4 is automobile starter M.
Now the principle of work that is set to example explanation short-circuit alarming circuit of the present invention for accumulator positive polar curve with this short-circuit alarming circuit: in the time that driver start-ups a car, accumulator is powered to automobile starter M by conductor wire core 26, external insulation layer 25 is for by conductor wire core 26 and vehicle frame, the metal electrical isolation such as support, therefore, in the time that external insulation layer 25 is not damaged, conductive layer 24 cannot be in electrical contact with metal species supports such as vehicle frames, therefore, be not configured to the current supply circuit that warning device 3 is powered, so electric wire 2 of the present invention is the same with common accumulator positive polar curve, play the effect by battery positive voltage alignment automobile starter M power supply, warning device 3 is in off-position.When electric wire 2 is because interfering while causing external insulation layer 25 to be worn with the metal species support such as vehicle frame, conductive layer 24 will contact with metal species support, now electric current can pass through battery positive voltage, warning device 3, conductive layer 24, metal species support is got back to battery terminal negative, be formed as the current supply circuit that warning device 3 is powered, warning device 3 will be reported to the police, remind driver's accumulator positive polar curve to interfere, need to process, now, because metal species support not yet galls inner insulating layer 27, conductor wire core 26 does not also contact with metal species support, therefore, can there are not conductor wire core 26 short circuits, problem on fire.
In order to increase the application flexibility of short-circuit alarming circuit of the present invention, make user can select to utilize this short-circuit alarming circuit to produce warning and make user after short-circuit alarming circuit produces warning, first to close warning again alert event to be processed, as shown in Figure 5, short-circuit alarming circuit of the present invention can also comprise and warning device 3 is connected in series in the Alarming control switch K between the positive pole of power supply 1 and the conductive layer 24 of electric wire 2.
Describe structure of the present invention, feature and action effect in detail according to the embodiment shown in graphic above; the foregoing is only preferred embodiment of the present invention; but the present invention does not limit practical range with shown in drawing; every change of doing according to conception of the present invention; or be revised as the equivalent embodiment of equivalent variations; when not exceeding yet instructions and illustrating contain spiritual, all should be in protection scope of the present invention.
