Patent documentation 1: the flat 10-335046 communique of Japanese open patent
Patent documentation 2: the flat 10-340778 communique of Japanese open patent
Patent documentation 3: the Japan Patent spy opens the 2005-183018 communique
In the heater wire shown in the patent documentation 1, have the very low economic problems of productivity owing to following three operations are the repetition operation: first operation, with the first heating silk thread helically twist with the fingers around, in its periphery first fuse layer is set; Second operation is twisted with the fingers around the second heating silk thread at the periphery helically of first fuse layer, in its periphery second fuse layer is set; And the 3rd operation, twist with the fingers around holding wire at the periphery helically of second fuse layer, and then insulating barrier is set in its periphery.In addition, in above-mentioned triplen, the covering that holding wire or heating wire tape are peeled off insulating barrier or fuse layer with damaging is not the work that needs very much proficiency, has the big problem of operating efficiency and poor reliability.
And then, in said structure, exist and to consider the situation that the first heating silk thread and the second heating silk thread must be connected in series and use from desired caloric value aspect.Reduce stray field for the magnetic field cancellation that will produce under this condition, need be with an end of the first heating silk thread and a terminal shortcircuit of the second heating silk thread, the first heating wire line end that consideration is derived from the other end of heating soft wire, the second heating wire line end, and the laying of two ends the heating utensil of holding wire are connected to the internal terminal of end connector.
For example under the situation of electric heating blanket, the requirement relevant with the arrangement architecture of the internal terminal of end connector is, two in the outside is used for heating soft wire, two of inboards is used for holding wire as standard, must make one of the first heating silk thread or the second heating silk thread to be quite long bare wire, this point lacks fail safe, the patchcord that needs insulation to cover is the work that needs very much proficiency and time.Like this, consider the laying in the heating utensil after, reliability high and economically with heating soft wire and holding wire endways in the internal terminal of connector wiring be unusual difficulty.
The described heater wire of first execution mode of above-mentioned patent documentation 2, to twist with the fingers at the periphery helically of heart yearn and be wound with the heating silk thread and carry out twisting with the fingers at two heating lines that its periphery is provided with fuse layer, be wound with holding wire at its periphery helically sth. made by twisting, and then be formed with insulating barrier in its periphery.Therefore, compare, repeat operation, increased a operation twisting with the fingers though reduced one with the execution mode of record in the above-mentioned patent documentation 1.In addition, two sections that sth. made by twisting is formed can not form circular, therefore exist to twist with the fingers the significant problem of the holding wire on the periphery of twisting with the fingers structure being cut off easily around two when forming the insulating barrier of most peripheral.And then in this section, holding wire not being brought the covering of peeling off insulating barrier with damaging is the work that needs very much proficiency, has the low big problem of operating efficiency and reliability.But, because two heating lines are insulated covering, therefore can be on the basis of the laying in having considered the heating utensil reliability high and carry out wiring in the internal terminal of connector endways economically.And then, in the described heater wire of the 3rd execution mode of above-mentioned patent documentation 2, to have the periphery helically twist with the fingers around the first heating line of holding wire and the second heating line to twisting with the fingers, and around two heating lines, be formed with the insulating barrier that section is a circular, therefore compare with the execution mode of above-mentioned patent documentation 1, repeat operation though reduced one, existing has increased a uneconomic problem to the operation of sth. made by twisting.The winding process of the heater wire of this structure, insulation cover and to extrude operation, the cloth line procedures in the internal terminal of connector all is reasonable and economic operations endways, but existence has increased this reason to the problem of sth. made by twisting operation to be, only on the first heating line, twist with the fingers and be wound with holding wire, therefore shielded the magnetic field that produces from this heating line to a certain extent, thereby generation is inhomogeneous on the intensity of the stray field of two heating lines.In order not eliminate reducing of this inhomogeneous stray field intensity that just can obtain to be scheduled to, need be to the structure of twisting with the fingers.
Patent documentation 3 described heater wires, to twist with the fingers the heating wire that is wound with the heating silk thread and is provided with insulating barrier in its periphery at the periphery helically of heart yearn, the line of return with above-mentioned heating wire same structure, and twist with the fingers at the periphery helically of heart yearn and to be wound with holding wire and to carry out Twist at the detection line that its periphery is provided with insulating barrier and close, perhaps the periphery at the wire harness that aligns is formed with whole insulating barrier for circular section profile shape, so three heating wires that constituted, the line of return, reach detection line and can make by unduplicated operation arranged side by side respectively, can realize the raising of production efficiency.In addition, this heating wire, the line of return, and detection line cover independently of one another, it is more or less freely therefore each silk thread not to be peeled off the covering of insulating barrier with bringing damage, does not have the big problem of bringing operating efficiency and reliability deterioration.
In addition, considered on the basis in the laying in the heating utensil wiring in the internal terminal of connector endways, also because above-mentioned heating wire, the line of return, and detection line cover independently of one another, therefore reliability is high and constitute economically easily.In this patent documentation 3, above-mentioned patent documentation 1 and 2 problem points are significantly improved.Yet this structure with three inner cover makes the external diameter chap of heating soft wire, produces other big problems of the mood variation of using the heating utensil of having laid.
Summary of the invention
The object of the present invention is to provide a kind of heating soft wire, can significantly reduce stray field, by heart yearn, heating silk thread, and the flexible cord element that constitutes of covering part will generate heat earlier effectively when the abnormal heating silk thread and detection line short circuit, two silk thread short circuits of generating heat in the time of can preventing to switch on afterwards.
And then other purposes of the present invention are to provide a kind of heating soft wire that can realize the raising of production efficiency and processability.
To achieve these goals, technical scheme 1 described heating soft wire of the present invention is characterised in that, have: the first flexible cord element, comprise first heart yearn, on first heart yearn with the first heating silk thread of predetermined spacing screw winding, will be above-mentioned first covering part that covers of the first heating silk thread insulation, reach detection line at the periphery screw winding of above-mentioned first covering part; The second flexible cord element, comprise second heart yearn, on above-mentioned second heart yearn than above-mentioned first heart yearn on screw winding the above-mentioned first heating silk thread sparsely screw winding the second heating silk thread, and will be above-mentioned second covering part of the second heating silk thread insulation covering; And outer cover, the above-mentioned first flexible cord element is become close in fact and has parallel portion with the second flexible cord arrangements of components, and covering this first flexible cord element and the second flexible cord element, when switching on above-mentioned first and second heating silk thread, the magnetic field that each silk thread that generates heat produces cancels each other out.
